Description

  The present invention relates to a method for introducing a fluid containing a workpiece into a cyclone body, a cyclone device, and a cyclone device in a cyclone that applies a swiveling motion to a fluid containing the workpiece to process the workpiece and the fluid. The present invention relates to a dust removing device, an incinerator, and an exhaust gas treatment method.

  A so-called cyclone (centrifugal force dust collector) that applies a centrifugal force to a fluid containing an object to be processed to process the object to be processed in the fluid is a pipe line to a fluid introduction port in a substantially cylindrical cyclone body. A fluid containing the object to be treated is introduced from the tangential direction toward the inner wall of the container body through this pipe line to generate a swirl speed component to give a centrifugal force, and the object to be treated has a higher specific gravity than the fluid. In general, an object is dropped onto the lower part of the container while pressing the object against the inner wall of the container body, and at the same time, the fluid from which the object to be processed is removed is discharged from a discharge pipe standing near the center of the container body.

  The principle of the cyclone device itself has already been invented in the 19th century, and various technologies applying the principle of the cyclone device have been developed in various fields (for example, Patent Documents 1 and 2).

JP-A-6-320055 Japanese Patent Laid-Open No. 10-34022

  However, in the conventional method of introducing a fluid through a pipe line, a physical load due to strain and vibration generated during the operation of the cyclone is concentrated on the joint part between the pipe line and the cyclone body, and therefore, cracks are generated at the joint part. There is a problem that damage is likely to occur.

  In general, as a conduit for introducing a fluid into the cyclone, a relatively thin pipe is used in order to improve the processing efficiency and not to disturb the swirling flow generated in the cyclone body. Preferably, therefore, the joint area between the pipe line and the cyclone body is reduced, and cracks and breakage are more likely to occur.

  Furthermore, when the inner diameter, size, shape, etc. are different between a so-called transfer pipe for transferring a fluid containing a workpiece generated in various industries to the vicinity of the cyclone and a pipe line for introducing the fluid into the cyclone body. However, the joining of the transfer pipe and the pipe line becomes complicated, and a special welding technique, a specially shaped connecting pipe, and the like are required.

  In particular, recently a so-called multi-cyclone system having a plurality of cyclones has been developed (for example, Patent Document 3). However, if the number of cyclones is increased, a pipe line for guiding fluid to each cyclone is required. There is a problem that the number of joints between the pipe line and the cyclone increases, and there is an increase in the number of portions where cracks or breakage may occur as many as the number of cyclones.

Japanese Patent Laid-Open No. 10-263439

  In addition, in such a multi-cyclone system, securing the installation location of the piping due to the increase in the number of piping for introducing the fluid into the cyclone main body becomes a problem, for example, the exhaust gas of automobiles, for example, It is physically impossible to install it on the vehicle body as a processing device or the like.

  Therefore, the present inventor has made extensive studies to solve such problems, and as a result, the object to be processed in the cyclone comprising the cyclone main body for fluid swirling, the fluid inlet for introducing fluid, and the discharge pipe for discharging fluid. A method of introducing a fluid containing a cyclone into a cyclone body, wherein at least a part or all of the cyclone is surrounded by an introduction container, the fluid introduction port is exposed in the introduction container, and the fluid containing an object to be processed is introduced. A method for introducing a fluid containing an object to be treated into a cyclone main body, characterized by introducing the fluid introduced into the introduction container into the cyclone main body without going through continuous piping by introducing the fluid into the container ( Hereinafter, this method is referred to as the method of the present invention).

  At the same time, the inventor is a cyclone comprising a cyclone body for fluid swirling, a fluid inlet for fluid introduction and a discharge pipe for fluid discharge, and a container surrounding at least a part or all of the cyclone, The cyclone device (hereinafter referred to as the device of the present invention) comprising: an introduction container for exposing the fluid introduction port; and an introduction pipe for introducing a fluid containing an object to be processed into the introduction container. It came to do.

  That is, the present inventor surrounds at least part or all of the cyclone with an introduction container, exposes the fluid introduction port in the introduction container, and introduces a fluid including an object to be processed into the introduction container. In other words, the fluid containing the object to be processed is introduced through the introduction container without directly joining the transfer pipe for transferring the fluid containing the object to be processed discharged from various industries to the vicinity of the cyclone and the fluid inlet in the cyclone. By introducing into the cyclone body, the joint part between the introduction pipe and the fluid introduction pipe is eliminated, and the physical load due to strain and vibration generated during the operation of the cyclone is concentrated on the joint part between the pipe line and the cyclone body. This solves the problem of cracks and breakage caused by hanging.

  In addition, the present inventor does not directly join the transfer pipe and the fluid introduction port in the cyclone, but introduces a fluid including an object to be processed into the cyclone main body through the introduction container. Even when the inner diameter, size, shape, etc. of the mouth are different, it has been found that a special welding technique, a connecting pipe and the like are unnecessary, and an extremely inexpensive introduction system can be constructed.

  Further, in a so-called multi-cyclone system using a plurality of cyclones, at least a part or all of each cyclone in the plurality of cyclones is surrounded by one introduction container and each fluid introduction port in the plurality of cyclones in the introduction container. By exposing this, it was found that complicated piping equipment is no longer required and a multi-cyclone system with a very simple configuration can be constructed.

  In addition, by constructing in this way, that is, by introducing the fluid containing the workpiece into the cyclone main body through the introduction container without directly introducing the fluid containing the workpiece into the cyclone main body, the workpiece in the fluid is introduced. It has also been found that a relatively rough fluid within the container and a relatively clean fluid can be introduced into the cyclone body, and as a result, the processing efficiency of the fluid can be improved.

  In particular, the introduction container has a substantially cylindrical shape, surrounds the periphery of the cyclone main body by the introduction container, introduces a fluid containing an object to be processed from the tangential direction of the introduction container, and swirls the fluid in the introduction container. As a result, the roughing efficiency in the introduction container of the object to be processed in the fluid is improved, and the silencing function can be imparted to the cyclone device.

  The present invention has been completed on the basis of the above-described knowledge, and has a simple and high physical strength and can improve the processing efficiency. It is another object of the present invention to provide a dust removing device, an incinerator, and an exhaust gas processing method provided with the device.

  The method of the present invention, which is a means for solving the above-described problems, includes a cyclone body for fluid swirling, a fluid inlet for fluid introduction, and a discharge pipe for fluid discharge. An introduction method, wherein at least a part or all of the cyclone is surrounded by an introduction container, the fluid introduction port is exposed in the introduction container, and a fluid including an object to be processed is introduced into the introduction container, The fluid introduced into the introduction container is introduced into the cyclone main body without passing through continuous piping.

  The apparatus of the present invention is a cyclone device that applies a swirling motion to a fluid containing an object to be processed to process the object to be processed in the fluid. The cyclone device includes a cyclone main body for fluid rotation, a fluid introduction A cyclone comprising a fluid inlet and a fluid discharge pipe, a container enclosing at least a part or all of the cyclone, wherein the container introduces the fluid inlet in the container, and an object to be processed It is characterized by comprising an introduction pipe for introducing a fluid containing it into the introduction container.

Furthermore, the dust removing device and the incinerator according to the present invention comprise the device according to the present invention, and the exhaust gas processing method according to the present invention is applied to an internal combustion engine using the device according to the present invention. The exhaust gas discharged is treated.
Hereinafter, the method of the present invention, the device of the present invention, the dust removing device provided with this device, the incinerator, and the exhaust gas processing method will be described in detail in order.

  The “fluid containing the object to be treated” that is the object to be treated by the method of the present invention has fluidity that can flow quickly without staying in the cyclone used in the method of the present invention. There is no particular limitation, and the state may be liquid or gas.

  Specifically, for example, emissions from various industries such as manufacturing, power generation, construction, waste disposal, and agriculture, and emissions from various transportations such as motorcycles, automobiles, trucks, buses, locomotives and ships. In short, the method of the present invention is intended for all fluids including the object to be processed that are generated by some production activity.

  In the method of the present invention, the cyclone into which the fluid containing the object to be treated is introduced is not particularly limited, and a cyclone main body for fluid swirling, a fluid inlet for introducing fluid, and a fluid discharging outlet. A conventionally known cyclone composed of a discharge pipe can be appropriately used.

  The method of the present invention is a method for introducing a fluid containing the object to be treated into the cyclone body, wherein at least part or all of the cyclone is surrounded by an introduction container and the fluid introduction is performed in the introduction container. The greatest feature is that the fluid introduced into the introduction container is introduced into the cyclone main body without passing through the continuous pipe by exposing the mouth and introducing the fluid containing the workpiece into the introduction container. Have

  That is, in the method of the present invention, first, at least a part or all of the cyclone is enclosed (sealed) with the introduction container, and the fluid introduction port for introducing the fluid into the cyclone body is exposed in the introduction container.

  In this state, if the fluid containing the object to be treated is introduced into the introduction container, there is no escape path for the introduced fluid other than the fluid introduction port in the introduction container. It is sent to the main body.

That is, the method of the present invention is a method for introducing an introduction container without directly connecting a pipe for transferring a fluid containing an object discharged from various industries to the vicinity of the cyclone and a fluid introduction port for introducing the fluid into the cyclone body. By introducing the fluid containing the object to be processed into the cyclone main body through the pipe, the joint portion between the pipe for transferring the fluid and the fluid introduction pipe is eliminated, and the physical load due to strain and vibration generated during the operation of the cyclone is affected. Problems such as cracks and breakage caused by concentrating on the joint between the pipe and the cyclone body can be solved.

  In the method of the present invention, since the fluid containing the object to be processed is introduced into the cyclone main body through the introduction container without directly joining the transfer pipe and the fluid introduction port in the cyclone, the transfer pipe Even if the inner diameter, size, or shape of the fluid introduction port is different, a special welding technique, a specially shaped connecting pipe, or the like is unnecessary, and an extremely inexpensive introduction system can be constructed.

  Furthermore, in a so-called multi-cyclone system that uses a plurality of cyclones, at least a part or all of each cyclone in the plurality of cyclones is collectively enclosed by one introduction container, and each fluid in the plurality of cyclones is contained in the introduction container. By exposing the introduction port, complicated piping equipment is not required, and a multi-cyclone system with a very simple configuration can be constructed.

  In addition, by constructing in this way, that is, by introducing the fluid containing the workpiece into the cyclone main body through the introduction container without directly introducing the fluid containing the workpiece into the cyclone main body, the workpiece in the fluid is introduced. Compared with the case where the fluid is roughly roughened in the container and the fluid is directly introduced into the cyclone via the pipe, a relatively clean fluid can be introduced into the cyclone body, and as a result, the processing efficiency of the fluid can be improved. It can be done.

  As for roughing in the introduction container, in the method of the present invention, it is preferable that the tip of the fluid introduction port protrudes in the introduction container. With this configuration, an object to be treated in the fluid is introduced into the fluid. In order to enter the cyclone main body from the mouth, certain kinetic energy, directionality, and the like are required, and the roughening effect of the object to be processed in the fluid in the introduction container is significantly increased.

  Furthermore, in the method of the present invention, when the tip of the fluid introduction port is protruded in the introduction container, the fluid passing through the fluid introduction port can be directed to be introduced from the tangential direction toward the inner wall of the cyclone body. As a result, the fluid that has passed through the fluid introduction port can quickly start a turning motion in the cyclone body, and the processing efficiency in the cyclone can be improved.

  In particular, in the method of the present invention, a substantially cylindrical hollow body is used as the introduction container, the periphery of the cyclone main body is surrounded by the introduction container, and further, a fluid containing an object to be processed from the tangential direction toward the introduction container inner wall. It is preferable that the fluid is swirled in the introduction container.

  That is, by introducing a swiveling motion in the introduction container before introducing the fluid containing the treatment object into the cyclone body, a part or all of the treatment object in the fluid moves to the upper part in the introduction container. In other words, the fluid can not reach the fluid inlet in the cyclone, and repeatedly turns in the lower or middle part of the introduction container. As a result, the workpiece is further roughened and relatively clean. Fluid can be introduced into the cyclone body.

  The “substantially cylindrical shape” is not only a literal cylinder (cylindrical body) that is a rectangular parallelepiped in front view with the same inner diameter of the bottom surface and the ceiling surface, but also those having different inner diameters of the bottom surface and the ceiling surface, for example, a cone In a shape (bell-shaped or inverted bell-shaped) cut in a horizontal plane, or a shape whose inner diameter changes continuously or stepwise, in short, in the method of the present invention, “substantially cylindrical” It means all hollow bodies in which the fluid can swirl, in other words, all hollow bodies whose horizontal cross section is substantially a circle.

  Next, the device of the present invention will be described.

  The device of the present invention is a cyclone device that applies a centrifugal force to a fluid containing an object to be processed to process the object to be processed in the fluid, and the cyclone device includes a cyclone main body for fluid rotation, a fluid `` Cyclone '' consisting of a fluid introduction port for introduction and a discharge pipe for fluid discharge, a container surrounding at least a part or all of the cyclone, `` an introduction container '' that exposes the fluid introduction port in the vessel, And an “introducing pipe” for introducing a fluid containing the object to be processed into the introducing container.

  The “cyclone” used in the apparatus of the present invention is not particularly limited. That is, the principle of processing the processing object such as dust by rotating the introduced fluid and utilizing the centrifugal force is used. A conventionally known cyclone, that is, a general cyclone including a cyclone main body for fluid swirling, a fluid introduction port for introducing fluid, and a discharge pipe for discharging fluid can be suitably used.

  The “introducing container” used in the apparatus of the present invention is a container that encloses (seals) at least a part or all of the cyclone in the cyclone, and exposes the fluid inlet in the container.

  Furthermore, the “introducing pipe” used in the apparatus of the present invention is for introducing a fluid containing an object to be processed into the introduction container. Generally, an object to be processed discharged from various industries or the like is used. A transfer pipe that transfers the contained fluid to the vicinity of the cyclone is used as the introduction pipe.

  And in this invention apparatus, the fluid containing a to-be-processed object is introduce | transduced in the said introduction container from the said introduction pipe.

Since the fluid introduced into the introduction container has no escape path other than the fluid introduction port that guides the fluid to the cyclone body in the introduction container, the introduced fluid is sequentially fed into the cyclone body.

  Then, the fluid containing the object to be processed sent to the cyclone main body is given a swiveling motion in the cyclone main body, and the object to be processed having a higher specific gravity than the fluid is pressed against the inner wall of the cyclone main body and dropped to the lower part of the cyclone main body. At the same time, the processed fluid is discharged from a discharge pipe standing for discharge near the center of the container body.

  That is, in the apparatus of the present invention, a transfer pipe (introduction pipe) for transferring a fluid containing a workpiece discharged from various industries to the vicinity of the cyclone and a fluid introduction port for introducing the fluid into the cyclone body are directly connected. Without introducing the fluid containing the object to be processed into the cyclone main body through the introduction container, thereby eliminating the joint between the transfer pipe (introduction pipe) and the fluid introduction port, and the distortion generated during the operation of the cyclone. It is possible to solve problems such as cracks and breakage caused by a physical load caused by vibration being concentrated on the joint.

  Further, in the apparatus of the present invention, an introduction container can be used without directly joining a transfer pipe (introduction pipe) for transferring a fluid containing an object discharged from various industries to the vicinity of the cyclone and a fluid introduction port in the cyclone body. Even if the transfer pipe (introduction pipe) and the fluid introduction port have different inner diameters, sizes, or shapes by introducing the fluid containing the object to be processed into the cyclone body through the special welding technique or special shape Therefore, an extremely inexpensive introduction system can be constructed.

  Therefore, in the device of the present invention, the radial cross-sectional area of the fluid inlet can be freely selected. For example, the radial cross-sectional area of the fluid inlet is larger than the radial cross-sectional area (inner diameter) of the transfer pipe (introducing pipe). In other words, when the diameter cross-sectional area of the fluid inlet is smaller than the diameter cross-sectional area of the transfer pipe (introducing pipe), the speed of introducing the fluid into the cyclone body is increased. On the other hand, when the radial cross-sectional area of the fluid introduction port is configured to be larger than the radial cross-sectional area of the transfer pipe (introduction pipe), the introduction speed of the fluid to the cyclone body can be reduced, that is, By providing a difference between the radial cross-sectional area of the fluid inlet and the radial cross-sectional area of the inlet, the introduction speed of the fluid into the cyclone body can be controlled.

  However, in general, in order to improve the processing capacity in the cyclone, it is preferable to increase the introduction speed of the fluid into the cyclone body. Therefore, in the present invention, the diameter cross-sectional area of the fluid introduction port is set to the transfer pipe. It is preferable to make it smaller than the radial cross-sectional area of the (introducing pipe).

  Furthermore, in the apparatus of the present invention, by introducing a fluid containing an object to be processed into the cyclone main body through the introduction container, the object to be processed in the fluid is roughly roughened in the introduction container, and is connected via a continuous pipe. As compared with the case where the fluid is directly introduced into the cyclone, a relatively clean fluid can be introduced into the cyclone body, and as a result, the fluid processing efficiency can be improved.

  In particular, in the case of constructing a so-called multi-cyclone system that uses a plurality of cyclones, at least a part or all of each cyclone in the plurality of cyclones is collectively enclosed by a single introduction container, and the plurality of cyclones are included in the introduction container. By exposing each fluid inlet in the cyclone, complicated piping equipment is not required, and a multi-cyclone system with a very simple configuration can be constructed.

  Here, in the case of constructing a so-called multi-cyclone system that uses a plurality of cyclones in the device of the present invention, the total number of the plurality of cyclones is an even number, and the direction of the swirling flow of half of the plurality of cyclones is the remaining. It is preferable that the direction of the swirl flow of half of the cyclones is opposite to the direction of the swirl flow, so that the phase of the noise generated in each cyclone is reversed between the cyclones with different swirl flow directions, and the noise of each other The noise generated by canceling out the noise is very small, and it can also be used as a silencer (silencer) such as a muffler that reduces the engine sound generated from an internal combustion engine such as an automobile.

  By the way, there is an extreme wave (width) in the introduction speed of the fluid to be processed, that is, the exhaust gas discharge speed is slow according to the engine speed, for example, exhaust gas exhausted from an automobile engine or the like. If a so-called multi-cyclone system that uses a plurality of cyclones is used for those that cause extreme differences due to becoming faster or faster, the introduced fluid is divided and introduced into each cyclone. When the introduction speed is low, the centrifugal force generated by the swirling fluid in each cyclone becomes weak, and the processing efficiency may decrease.

  Therefore, in the case of using a so-called multi-cyclone system that uses a plurality of cyclones in the device of the present invention, it is preferable to change the distribution of the amount of fluid introduced into each cyclone arbitrarily or according to the fluid introduction speed, With this configuration, it is possible to mitigate a decrease in processing efficiency when the fluid introduction speed is low.

  Here, the means for changing the distribution of the introduction amount of the fluid to each cyclone according to any or the fluid introduction speed is not particularly limited, but specifically, for example, the fluid introduction port of each cyclone. A valve that can be opened and closed is provided, or a partition plate that has a lid that can be opened and closed is provided on the introduction container, so that the distribution of the amount of fluid introduced to each cyclone can be changed by arbitrarily closing and opening the valve and lid. In addition, sensors such as velocimeters are installed in some or multiple parts of the cyclone device such as transfer pipes (introduction pipes) and fluid introduction pipes, and the valves and lids automatically open and close according to the reaction of the sensors. A means for changing the distribution of the amount of fluid introduced into each cyclone can be mentioned.

  In the device of the present invention, it is preferable that the tip of the fluid introduction port protrudes in the introduction container, and by configuring in this way, in order for the workpiece in the fluid to enter the cyclone main body from the fluid introduction port. A certain kinetic energy, directionality, etc. are required, and the rough removal effect of the object to be processed in the fluid in the introduction container is remarkably increased.

  Further, in the apparatus of the present invention, the tip of the fluid introduction port for introducing the fluid into the cyclone main body is protruded in the introduction container so that the fluid is introduced from the tangential direction toward the inner wall of the cyclone main body through the fluid introduction port. When connected, it is possible to determine the introduction direction of the fluid into the cyclone body while passing through the fluid introduction port, and from this, the fluid that has passed through the fluid introduction port can quickly start a swiveling motion within the cyclone body. Can do it.

  The degree of protrusion at the tip of the fluid inlet is not particularly limited. However, if the protrusion is made extremely long, damage or cracks may occur due to vibration during the cyclone operation or physical resistance such as wind pressure received from the fluid. May occur.

  Therefore, the degree (length) of protrusion at the tip of the fluid introduction port in the device of the present invention is generally set to a ratio of about 0.05 to 1.0 times compared to the inner diameter of the ceiling surface of the cyclone body. In addition, a ratio of about 0.1 to 0.5 times is preferable.

  If the degree of protrusion at the tip of the fluid inlet is less than 0.05 times compared to the inner diameter of the ceiling surface of the cyclone body, the degree of protrusion may be too small and the efficiency of roughing in the introduction container may decrease. On the other hand, if it is 1.0 times or more, there is a possibility that breakage or cracks may occur due to vibration during cyclone operation, physical resistance received from the fluid, or the like.

  By the way, in this invention apparatus, it is preferable to surround the circumference | surroundings of a cyclone main body with an introduction container.

  That is, if the periphery of the cyclone body is surrounded by the introduction container, the joining area between the cyclone body and the introduction container is increased, and the durability of the cyclone device of the present invention can be further improved.

  At this time, it is preferable that the ceiling surface of the cyclone main body and the ceiling surface of the introduction container are brought into surface contact with each other, or the ceiling surface of the cyclone main body and the ceiling surface of the introduction container are constituted by a common member, as described above. By configuring, the durability of the device of the present invention can be further improved.

  In addition, if the periphery of the cyclone body is surrounded by the introduction container, the fluid containing the workpiece to be treated can be given a degree of freedom to go around the cyclone before reaching the fluid introduction port. Further, the rough removal effect of the object to be processed in the fluid in the introduction container is further increased.

  Therefore, in the apparatus of the present invention, it is preferable to use a substantially cylindrical hollow body as the introduction container, and surround the cyclone main body by the introduction container, and introduce a substantially cylindrical hollow body as the introduction container. Thus, the fluid containing the treated object can easily go around the cyclone body.

  In particular, in the apparatus of the present invention, a substantially cylindrical hollow body is used as the introduction container, and the circumference of the cyclone main body is surrounded by the introduction container, and the fluid is tangent toward the inner wall of the introduction container as the introduction pipe in the introduction container. By using what is introduced from the direction, it is preferable that the fluid containing the workpiece to be introduced into the introduction container is actively swirled within the introduction container.

  That is, if the fluid containing the object to be processed is swung in the introduction container before being introduced into the cyclone body, part or all of the object to be processed in the fluid cannot move to the upper part in the introduction container. In other words, the fluid can not reach the fluid inlet in the cyclone, and repeatedly turns in the lower or middle part of the introduction container. As a result, the relatively clean fluid from which the workpiece is further roughened is removed from the cyclone. It can be introduced into the main body.

  Surprisingly, it has been confirmed that the noise generated from the cyclone device is remarkably reduced by such a configuration.

  The reason for this is not clarified at this stage, but the noise generated by the swirling motion in the introduction container and the noise generated by the swirling motion in the cyclone body cancel each other and are generated from the cyclone device. It is considered that the noise is reduced. Therefore, by configuring in this way, it is possible to impart a silencing function to the cyclone device of the present invention, for example, so-called silencing explosive sound generated from an internal combustion engine. It can also be used as a muffler.

  The “substantially cylindrical shape” is not only a literal cylinder (cylindrical body) that is a rectangular parallelepiped in front view with the same inner diameter of the ceiling surface and the bottom surface, but also those having different inner diameters of the ceiling surface and the bottom surface, for example, a cone In a shape (bell-shaped or inverted bell-shaped) cut in a horizontal plane, or a shape whose inner diameter changes continuously or stepwise, in short, in the device of the present invention, “substantially cylindrical” It means all hollow bodies in which the fluid can swirl, in other words, all hollow bodies whose horizontal cross section is substantially a circle.

Here, when the fluid containing the object to be processed is swirled in the introduction container in the apparatus of the present invention, it is preferable that the fluid introduction port in the cyclone faces the swirl flow generated in the introduction container.
The reason for this is as follows.

  That is, when a fluid is introduced from a fluid introduction port in a general cyclone, the object to be processed in the fluid that passes through the fluid introduction port is distributed almost uniformly in the cross section of the fluid introduction port, so Thus, a workpiece having a uniform distribution density is introduced.

  For this reason, the workpiece that enters the cyclone body from a position near the cyclone body at the fluid inlet has a smaller radius of rotation than the particles that enter from the position away from the cyclone body at the fluid inlet, and the necessary centrifugal force is sufficient. In addition, the swirl flow is disturbed by contact with the swirl flow of the cyclone main body, so that the processing efficiency is lowered.

  In this regard, when a swirling motion is given to the fluid containing the object to be processed in the introduction container, the object to be processed in the fluid is pressed against the inner wall of the introduction container, that is, the distribution of the object to be processed in the fluid. If the fluid that has reached this distribution state is introduced into the cyclone body as it is, the processing efficiency is reduced due to the distribution state of the object to be processed in the fluid. The disadvantage of the conventional cyclone device can be solved.

  Therefore, in the apparatus of the present invention, it is preferable that the fluid introduction port in the cyclone is opposed to the swirl flow in the introduction container, and by configuring in this way, the distribution of the object to be processed in the fluid is directed toward the inner wall of the introduction container. Thus, the fluid in a biased state can be introduced into the cyclone body as it is, and the processing efficiency resulting from the state of introduction of the workpiece in the fluid can be improved.

  Also, with this configuration, the object to be processed in the fluid introduced into the cyclone main body is sufficiently distributed to be processed in an extremely short time, so that the cyclone main body (and the introduction container) can be shortened. Therefore, the present invention can also be applied to a field where a long cyclone device cannot be installed, and for example, it can be installed on a vehicle body as an exhaust gas treatment device for an automobile.

  By the way, when the fluid containing the object to be treated is swirled in the introduction container, the object to be treated is pressed against the inner wall of the introduction container, so that the distribution density of the object to be treated is the highest in the vicinity of the inner wall of the introduction container, and the center of the introduction container The distribution density of the object to be processed is gradually lowered toward the surface.

  Therefore, in this state, when the tip of the fluid introduction port in the cyclone body is along the inner wall of the introduction container, a fluid having a relatively large content of the object to be processed is introduced into the cyclone body.

  On the other hand, in this state, when the fluid inlet in the cyclone body is positioned on the center side of the inner wall of the introduction container, a relatively clean fluid is introduced into the cyclone body.

  That is, for example, when processing a fluid with a low content of an object to be processed or when using a cyclone with a high processing capacity, the fluid introduction port in the cyclone main body is placed along the inner wall of the introduction container, and the cyclone is covered in the cyclone. If a large amount of processed material is introduced, a large amount of processed material can be processed in the cyclone. Conversely, when processing a fluid having a high content of processed material or using a cyclone having a low processing capacity. In such a case, by positioning the fluid introduction port in the cyclone body closer to the center side than the inner wall of the introduction container, a large amount of processing object can be processed (roughly removed) in the introduction container.

  In the apparatus of the present invention, it is preferable that the position of the fluid introduction port in the introduction container is arbitrarily changed or appropriately changed according to the amount of the object to be processed in the fluid.

  For example, normally, exhaust gas discharged from an internal combustion engine such as an automobile engine has a high content of an object to be processed such as PM during low speed operation, while the combustion efficiency becomes high during high speed operation. Low content of workpieces.

  Therefore, in the apparatus of the present invention, it is preferable that the position of the fluid introduction port in the introduction container is arbitrarily changed or appropriately changed according to the amount of the processing object in the fluid. It is possible to cope with any change in the content of the object to be processed in the fluid according to the state or the like.

  When the fluid including the object to be processed is swung in the introduction container in the apparatus of the present invention, the introduction container is moved from the position where the introduction pipe in the introduction container is provided to the position where the fluid introduction port in the cyclone body is provided. In other words, the inner diameter of the ceiling surface of the substantially cylindrical introduction container is preferably smaller than the inner diameter of the bottom surface of the introduction container. The swirling speed of the introduced fluid can be accelerated until it reaches the fluid inlet in the cyclone, so that a stronger centrifugal force can be applied to the workpiece in the fluid and the cyclone body The introduction speed of the fluid can be increased.

  In this case, the inner diameter of the introduction container may be decreased continuously (slowly) from the bottom surface toward the ceiling surface. However, in the apparatus of the present invention, in particular, the inner diameter of the introduction container is stepped from the bottom surface toward the ceiling surface. In this way, each stage in the introduction container becomes a barrier, and it becomes difficult for the object to be processed in the fluid to exceed each stage in the introduction container. The efficiency of roughing inside is further improved.

  As described above, the device of the present invention is configured such that a part or all of the cyclone is surrounded by the introduction container, and further, part or all of the introduction container is sequentially added by one or more other introduction containers. By providing a plurality of introduction containers in this way, the object to be treated in the fluid is roughly removed in each introduction container, so that the processing efficiency of the entire cyclone apparatus of the present invention can be improved. is there.

  Note that one or a plurality of other introduction containers surrounding the introduction container can be the same as the introduction container surrounding the cyclone main body described above, and the description thereof is omitted here to avoid repetition, but of course. Each of the other introduction containers is provided with an introduction port (fluid introduction port) for introducing a fluid, and these introduction ports are arranged so as to be exposed or protruded in another introduction vessel surrounding the introduction vessel. It is.

  In the apparatus of the present invention, the introduction container is partitioned by one or more partition plates so that the interior of the introduction container is divided into a plurality of rooms, and the partition plate is bypassed so that fluid can move between adjacent rooms. A passage may be provided, and in this way, by dividing the inside of the introduction container into a plurality of rooms, the object to be processed in the fluid is roughly removed in each room, and the processing efficiency of the entire cyclone apparatus of the present invention can be improved. It can be improved.

  By the way, in the device of the present invention, in addition to the fluid introduction means using the introduction container, a container that surrounds at least a part or all of the cyclone, and uses a discharge container that exposes a discharge pipe in the container, It is preferable to use a fluid discharge means for discharging the fluid discharged from the discharge pipe to the outside of the cyclone without going through a continuous pipe.

  That is, in the apparatus of the present invention, by adopting the discharge means having such a configuration in addition to the introduction means, in other words, by introducing the introduction pipe and the discharge pipe independently from other pipes, It is possible to eliminate the joint between the pipe and the discharge pipe and other pipes, so that the physical load due to strain and vibration generated during the operation of the cyclone is applied to the joint between the introduction pipe and the discharge pipe and other pipes. It is possible to solve the problem of cracks and breakage due to concentration.

  Further, in the apparatus of the present invention, the introduction pipe and the discharge pipe are made independent of other pipes, so that even when the inner diameter, size, or shape of the introduction pipe or the discharge pipe and other pipes are different, they are special. Welding technology and connecting pipes are unnecessary, and an extremely inexpensive introduction / discharge system can be constructed.

  Further, in a so-called multi-cyclone system that uses a plurality of cyclone devices in combination, in addition to the introduction means, by adopting such a discharge means, at least a part or all of each cyclone in the plurality of cyclones is obtained. By enclosing them together with one discharge container and exposing each discharge pipe in the plurality of cyclones in the discharge container, no complicated piping equipment is required, and a multi-cyclone system with a very simple configuration can be constructed. is there.

  In addition, in the apparatus of the present invention, by adopting the discharge means having such a configuration in addition to the introduction means, the cyclone apparatus can be made compact and the installation space can be reduced, and the entire cyclone apparatus is further introduced. By enclosing the container and a casing (cover) as a discharge container, it is possible to prevent the cyclone body from being dented or deformed when subjected to an external impact, and thereby processing caused by the cyclone body being dented or deformed. It is possible to prevent a decline in capacity.

  In the apparatus of the present invention, the object to be processed roughly collected in the introduction container is collected in the introduction container, while the object to be processed processed in the cyclone is collected in the cyclone.

  Then, it is necessary to remove the collected object to be processed at an appropriate time or periodically.

  At this time, if the object to be treated is harmless to the human body, there is no particular problem except that the removal work is complicated, but PM (particulate pollutant), graphite and other substances contained in the exhaust gas of the automobile In the case of fine dust, there is a risk that health injuries such as pneumoconiosis may occur in workers who have inhaled this, and there are reports that PM and graphite contain a large amount of carcinogenic substances.

  Therefore, in the apparatus of the present invention, it is preferable to provide a catalyst and / or an adsorbent for detoxifying or adsorbing an object to be processed in the introduction container and / or the cyclone body, and in the introduction container or the cyclone body. It is preferable to treat the object to be treated and the catalyst in contact with each other.

  In the apparatus of the present invention, a part (or all) of the object to be processed is repeatedly swirled in the introduction container or in the cyclone body, so that it is rubbed against the inner wall during the swiveling motion and becomes a so-called burnout state. Finally, it has been confirmed that it gasifies into a gas such as carbon dioxide.

  Therefore, gas components such as NOx or SOx contained in the gasified object or fluid are entrained in the flow at the center of the cyclone and discharged from the discharge pipe together with the fluid.

  Therefore, in the apparatus of the present invention, a catalyst and / or an adsorbent that renders the gas component and the like harmless or adsorbs in the discharge container, and the catalyst or adsorbent and the gas component are brought into contact with each other for processing. It is preferable.

  That is, in the apparatus of the present invention, the treatment efficiency can be further improved by providing the catalyst and / or the adsorbent in at least one place selected from the cyclone main body, the introduction container, and the discharge container. With only the mechanism, gas components such as NOx and SOx that are difficult to collect can be efficiently processed.

  In particular, by providing the catalyst and / or adsorbent in at least one location selected from the cyclone main body, the introduction container and the discharge container, that is, by providing the catalyst and / or adsorbent adjacent to or near the cyclone, The heat of the fluid such as exhaust gas and soot and the heat generated from the cyclone device during the cyclone operation can be efficiently transferred to the catalyst and the adsorbent. As a result, the activity of the catalyst and the adsorbent can be significantly improved. Can do it.

  Here, the catalyst used in the device of the present invention is particularly limited as long as it can process the object to be processed and the gas component in a substantially safe state by contacting the object to be processed or the gas component in the fluid. Specifically, for example, at least one metal oxide selected from titanium, vanadium, zinc, zirconium, niobium, molybdenum, tin, tantalum, lanthanum, cerium, etc., nickel catalyst, platinum catalyst, alumina A conventionally known inorganic catalyst represented by a catalyst or the like, a so-called three-way catalyst composed of platinum, rhodium and palladium, or a liquid or mist of urea crystal or ammonia can be appropriately selected and used.

  The adsorbent is not particularly limited as long as it can adsorb the object to be processed by contacting the object to be processed in the fluid. Specifically, for example, activated carbon, silica gel, zeolite Alternatively, a conventionally known adsorbent such as a porous ceramic powder or granule can be appropriately selected and used.

  In addition, in installing the catalyst and the adsorbent in at least one place selected from the cyclone main body, the introduction container, and the discharge container in the apparatus of the present invention, the catalyst and the adsorbent are directly used as the preliminary swivel main body, the cyclone main body, and the introduction container. And at least one place selected from the discharge container, and the catalyst or adsorbent is applied to at least one inner wall selected from the preliminary swivel body, the cyclone body, the introduction container, and the discharge container. It may be supported by adhesion, application, or other means.

  Furthermore, when the catalyst and adsorbent are provided in the introduction container and the discharge container, the introduction container and the discharge container are appropriately partitioned by a partition plate having a shape through which a fluid such as a filter, a net, or a punching metal can pass. The catalyst or adsorbent may be added, and the catalyst or adsorbent is appropriately supported on a support (for example, a plate, rod, sphere, network, or the like made of alumina, silica, ceramic, cordierite, titania, stainless steel, etc. Attached to the inner wall, floor surface or ceiling surface of the introduction container or discharge container by attaching, applying, fitting, etc. to a filter, honeycomb, columnar or cylindrical support) By laminating in the introduction container or the discharge container, or by appropriately partitioning the introduction container or the discharge container by a support carrying the catalyst or adsorbent. And than may be provided, if desired by, it's may be used in combination of these mounting means as appropriate.

  The dust removing device of the present invention is a novel dust removing device including the device of the present invention, that is, without containing a fluid containing dust discharged in various industries through a continuous pipe. Introduced into the cyclone main body and processed, it has excellent durability, high processing efficiency, and the time required to remove the collected material to be collected is significantly prolonged, or so-called maintenance-free is realized. It is a very good dust removal device that can.

  Further, the incinerator of the present invention is a novel incinerator having the above-mentioned apparatus of the present invention, that is, smoke containing incinerated ash containing harmful substances such as dioxin discharged from the incinerator. It is introduced into the cyclone body without processing through continuous piping, and has excellent durability and high processing efficiency.In particular, by giving repeated swirling motion in the introduction container, harmful substances such as dioxin can be removed. It can also be gasified into carbon dioxide and other gases, and it is extremely excellent in that it can remarkably prolong the interval required to remove the collected object to be processed, or realize so-called maintenance-free operation. It is an incinerator.

  The exhaust gas treatment method of the present invention is characterized in that exhaust gas discharged from an internal combustion engine is treated by using the apparatus of the present invention, that is, represented by an engine such as an automobile or a ship. Exhaust gas discharged from an internal combustion engine is introduced into the cyclone main body without going through continuous piping and processed, and it has excellent durability, high processing efficiency, and removal of collected objects to be processed It is possible to remarkably prolong the interval that requires maintenance, and to realize so-called maintenance-free, and it is possible to realize so-called maintenance-free, and it is unnecessary to install a silencer such as a muffler due to the silencing effect by using a plurality of cyclones. This is a gas processing method.

A dust removing device, an incinerator, and an exhaust gas processing method.

  The method of the present invention is a method for introducing fluid into a cyclone body including a workpiece in a cyclone comprising a cyclone body for fluid swirling, a fluid inlet for fluid introduction, and a discharge pipe for fluid discharge, The cyclone is introduced into the introduction container by enclosing at least a part or all of the cyclone in the introduction container, exposing the fluid introduction port in the introduction container, and introducing a fluid including an object to be processed into the introduction container. The fluid is introduced into the cyclone body without going through continuous piping.

  The device of the present invention is a cyclone comprising a cyclone main body for fluid swirling, a fluid inlet for introducing fluid, and a discharge pipe for discharging fluid, and a container surrounding at least part or all of the cyclone, And the introduction container for exposing the fluid introduction port and the introduction pipe for introducing the fluid containing the object to be processed into the introduction container.

  That is, the present invention can be rephrased by surrounding at least a part or all of the cyclone with an introduction container, exposing the fluid introduction port in the introduction container, and introducing a fluid containing an object to be processed into the introduction container. For example, the fluid containing the object to be processed through the introduction container without directly joining the transfer pipe for transferring the fluid containing the object to be processed discharged from various industries to the vicinity of the cyclone and the fluid introduction port in the cyclone. By introducing into the cyclone body, the joint part between the introduction pipe and the fluid introduction pipe is eliminated, and the physical load due to strain and vibration generated during the operation of the cyclone is concentrated on the joint part between the pipe line and the cyclone body. This solves the problem of cracks and breakage.

  In addition, the present invention is not intended to directly connect a transfer pipe for transferring a fluid containing an object to be processed discharged from various industries to the vicinity of the cyclone and a fluid introduction port in the cyclone via the introduction container. Even if the transfer pipe and the fluid introduction port have different diameter cross-sectional areas (inner diameter, size) or shape by introducing the fluid containing into the cyclone body, a special welding technique, a connecting pipe, etc. are not required. An extremely inexpensive introduction system can be constructed.

By exposing the tip of the inlet, complicated piping equipment is not required, and a multi-cyclone system with a very simple configuration can be constructed.

  In addition, by introducing the fluid containing the treatment object directly into the cyclone body through the introduction container without directly introducing it into the cyclone body, the treatment object in the fluid is roughly roughened in the introduction container. A clean fluid can be introduced into the cyclone body, and as a result, the processing efficiency of the fluid can be improved.

  In particular, the introduction container has a substantially cylindrical shape, surrounds the periphery of the cyclone main body by the introduction container, introduces a fluid containing an object to be processed from the tangential direction of the introduction container, and swirls the fluid in the introduction container. As a result, the roughing efficiency in the introduction container of the object to be processed in the fluid is improved, and a silencing function can be imparted to the cyclone device.

  The dust removing device of the present invention is a novel dust removing device including the device of the present invention, and has an excellent durability, high processing efficiency, and an operation for removing the collected object to be processed. It is a very good dust removing device that can significantly lengthen the required interval or realize so-called maintenance-free.

It is a very excellent method for treating exhaust gas that eliminates the need for mounting.

  Examples of the present invention will be described below, but the present invention is not limited to these examples.

  FIG. 1 is a schematic diagram showing a device 1 of the present invention according to Example 1, and the inside of the introduction container 3 can be visually recognized by showing the introduction container 3 in a transmissive state.

  The inventive device 1 according to this embodiment includes a cyclone 2, an introduction container 3, and an introduction pipe 4.

  The cyclone 2 is a conventionally known cyclone that utilizes the principle of rotating an introduced fluid and processing an object to be processed such as dust using its centrifugal force, and is a substantially cylindrical body portion 211 for fluid rotation. And a general cyclone comprising a cyclone main body 21 comprising a substantially conical body lower part 212 provided continuously at the lower part of the body part, a fluid introduction port 22 for introducing fluid, and a discharge pipe 23 for discharging fluid.

  The introduction container 3 surrounds at least a part or all of the cyclone in the cyclone, and exposes the fluid introduction port 22 in the container.

  Furthermore, the introduction pipe 4 is for introducing a fluid containing the object to be treated into the introduction container 3. Generally, the fluid containing the object to be treated discharged from various industries or the like is supplied near the cyclone. A transfer pipe that transports up to is used as an introduction pipe.

  In this embodiment, a fluid containing the object to be processed is introduced into the introduction container 3 from the introduction pipe 4.

  Since the fluid introduced into the introduction container 3 has no escape path other than the fluid introduction port 22 in the introduction container 3, the introduced fluid is sequentially fed into the cyclone body 21.

  Then, the fluid including the workpiece to be sent to the cyclone main body 21 is given a swivel motion in the cyclone main body 21, and the cyclonic main body 21 is pressed while pressing the workpiece having a higher specific gravity than the fluid against the inner wall of the cyclone main body 21. The fluid is dropped to the lower part, and the treated fluid is discharged from the discharge pipe 23 for discharge standing near the center of the cyclone main body 21.

  That is, in the present embodiment, the introduction pipe 4 and the fluid introduction port 22 are not directly connected to each other, but the introduction pipe and the fluid are introduced into the cyclone body 2 via the introduction container 3. The joint portion of the introduction port is eliminated, and problems such as cracks and breakage caused by concentration of physical loads due to strain and vibration generated during the operation of the cyclone 2 on the joint portion can be solved.

  Further, in this embodiment, the introduction pipe 4 and the fluid introduction port 22 are not directly joined to each other, but the introduction pipe 4 and the fluid are introduced into the cyclone main body 21 through the introduction container through the introduction container. Even when the diameter cross-sectional area (inner diameter, size) or shape of the introduction port 22 is different, a special welding technique, a connecting pipe or the like is not required, and an extremely inexpensive introduction system can be constructed.

  Furthermore, by providing a difference between the radial cross-sectional area of the introduction pipe 4 and the radial cross-sectional area of the fluid introduction port 22, the introduction speed of the fluid to the cyclone body 21 can be controlled. By making the diameter cross-sectional area of the fluid introduction port 22 smaller than the diameter cross-sectional area of 4, the introduction speed of the fluid to the cyclone body 21 can be increased, and as a result, the processing efficiency can be remarkably improved.

  Moreover, by comprising in this way, ie, not introducing the fluid containing a to-be-processed object directly into the cyclone main body 21, but introducing into the cyclone main body via the introduction container 3, the to-be-processed object in a fluid is obtained. Compared to the case where the fluid is roughly roughened in the introduction container 3 and the fluid is directly introduced into the cyclone via the pipe, a relatively clean fluid can be introduced into the cyclone main body 21 and, as a result, the fluid processing efficiency is improved. It can be made.

  In this embodiment, the tip of the fluid introduction port 22 protrudes in the introduction container 3 and the fluid introduction port 22 is connected so that the fluid is introduced from the tangential direction toward the inner wall of the cyclone main body 21. is doing.

  As shown in FIG. 2 (permeation view of the cyclone device 1 according to the present embodiment as viewed from above (on the discharge pipe 23 side)), when the tip of the fluid introduction port 22 protrudes in the introduction container 3, it is introduced. In order for an object to be processed in the fluid introduced from the port 4 into the introduction container 3 to enter the cyclone main body 21 from the fluid introduction port 22, certain kinetic energy and directionality are required. The roughening effect of the object to be processed in the fluid in 3 is remarkably increased.

  Further, when the fluid introduction port 22 is connected so that the fluid is introduced from the tangential direction toward the inner wall of the cyclone main body 21, the fluid introduction direction to the cyclone main body 21 while passing through the fluid introduction port 22. From this, the fluid that has passed through the fluid inlet 22 can quickly start a swiveling motion within the cyclone body 21.

  FIG. 3 is a schematic diagram showing the device 1 of the present invention according to the second embodiment. By showing the introduction container 3 in a transmissive state, the inside of the introduction container 3 can be visually recognized.

  The inventive device 1 according to this embodiment includes a cyclone 2a, a cyclone 2b, an introduction container 3 and an introduction tube 4.

  That is, the device 1 of the present invention according to the present embodiment is a so-called multi-cyclone system using a plurality of (two) cyclones 2a, 2b in combination, and each of the cyclones 21a, 21b in the plurality (two) cyclones 2a, 2b. At least a part or all of the fluid is surrounded by one introduction container 3 and the fluid introduction ports 22a and 22b in the plurality (two) of the cyclones 2a and 2b are projected in the introduction container 3. It is a multi-cyclone system with a very simple configuration that eliminates the need for complicated piping equipment.

  In the present embodiment, the direction of the swirling flow of one cyclone 2a among the plurality (two) of the cyclones 2a, 2b is opposite to the direction of the swirling flow of the other cyclone 2b. By configuring in this way, the phase of the noise generated in each cyclone is reversed between cyclones with different swirl flow directions, and the noise generated by canceling each other's noise becomes very small. It is.

  In the so-called multi-cyclone system using a plurality of cyclones 2a and 2b as in the present embodiment, if there is a significant range in the introduction speed of the fluid to be processed, each cyclone 2a, It is preferable to change the distribution of the introduction amount of the fluid to 2b. By configuring in this way, it is possible to mitigate a decrease in processing efficiency when the introduction rate of the fluid is low.

  Here, the means for changing the distribution of the introduction amount of the fluid to each of the cyclones 2a and 2b according to any or the fluid introduction speed is not particularly limited, but specifically, for example, each cyclone 2a. 2b is provided with a valve that can be opened and closed at the fluid introduction ports 22a and 23b, or a partition plate having a lid that can be opened and closed is provided on the introduction container 3, and the cyclone 2a can be opened and closed arbitrarily. The distribution of the amount of fluid introduced to 2b is changed, or an anemometer is provided in a part or a plurality of locations of the cyclone device 1 such as the transfer pipe (introduction pipe) 4 and the fluid introduction port 22, depending on the numerical value of the anemometer. And a means for changing the distribution of the amount of fluid introduced to each of the cyclones 2a and 2b so that the valve and the lid are automatically opened and closed.

  FIG. 4 is a schematic view showing the device 1 of the present invention according to the third embodiment. By showing the introduction container 3 in a transmissive state, the inside of the introduction container 3 can be visually recognized.

  The inventive device 1 according to this embodiment includes a cyclone 2, an introduction container 3, and an introduction tube 4, and the cyclone main body 21 is surrounded by a substantially cylindrical introduction container 3.

  That is, the device 1 of the present invention according to the present embodiment surrounds the periphery of the cyclone main body 2 by the substantially cylindrical introduction container 3, and the joining area between the cyclone main body 21 and the introduction container 3 is increased. The durability can be improved.

  In the present embodiment, the ceiling surface of the cyclone body 21 and the ceiling surface of the introduction container 3 are formed by a common member, that is, the ceiling surface of the cyclone body 21 and the ceiling surface of the introduction container 3 are partially used in common. As a result, the durability is further improved.

  And in this invention apparatus 1 which concerns on a present Example, while using the substantially cylindrical hollow body as the introducing | transducing container 3, the circumference | surroundings of the cyclone main body 21 are enclosed by this introducing | transducing container 3, and as the introducing | transducing pipe | tube 4 in the said introducing | transducing container 3 The fluid that introduces the fluid from the tangential direction toward the inner wall of the introduction container 3 is used, so that the fluid including the workpiece to be introduced into the introduction container 3 swirls in the introduction container 3. Is given.

  That is, the device 1 of the present invention according to the present embodiment actively rotates in the introduction container 3 before introducing the fluid containing the object to be processed into the cyclone main body 21, and is thus configured. Part or all of the object to be processed in the fluid cannot move to the upper part in the introduction container 3, that is, cannot reach the fluid introduction port 22 in the cyclone 2, and the lower part in the introduction container 3. As a result, a relatively clean fluid from which the workpiece is further roughened can be introduced into the cyclone main body 21.

  Furthermore, in the device 1 of the present invention according to the present embodiment, the fluid introduction port 22 in the cyclone 2 is opposed to the swirl flow in the introduction container 3.

  That is, as shown in the top view of the cyclone device 1 according to the present embodiment in FIG. 5 (from the discharge pipe 23 side), in this embodiment, a swirling motion is performed on the fluid containing the workpiece in the introduction container 3. Therefore, the object to be processed in the fluid is pressed against the inner wall of the introduction container, that is, the distribution of the object to be processed in the fluid is biased toward the inner wall of the introduction container.

  In the present embodiment, the fluid introduction port in the cyclone is opposed to the swirl direction of the fluid in the introduction container, so that the distribution of the object to be processed in the fluid is biased toward the inner wall direction of the introduction container 3. This fluid can be introduced into the cyclone main body 21 as it is, and the reduction in processing efficiency due to the state of introduction of the workpiece in the fluid can be eliminated.

  Also, with this configuration, the object to be processed in the fluid introduced into the cyclone main body 21 is sufficiently distributed to be processed in an extremely short time, and thus the cyclone main body 21 (and the introduction container 3). Therefore, it can be applied to a field where installation space for a long cyclone device cannot be secured. For example, it can be installed on a vehicle body as an exhaust gas treatment device for an automobile.

  By the way, as shown to Fig.6 (a) (permeation | transmission figure which looked at the cyclone apparatus 1 which concerns on a present Example from upper direction (discharge pipe 23 side)), in this Example, the fluid inlet opening front-end | tip 22 in the cyclone main body 21 is shown. Along the inner wall of the introduction container 3, a fluid having a relatively large content of the object to be processed is introduced into the cyclone main body 21.

  On the other hand, as shown in FIG. 6B (permeation view of the cyclone device 1 according to the present embodiment as viewed from above (the discharge pipe 23 side)), in this embodiment, the fluid introduction port 22 in the cyclone main body 21 is introduced. When it is located closer to the center than the inner wall of the container 3, a relatively clean fluid is introduced into the cyclone body.

  That is, when processing a fluid with a low content of the object to be processed or using a cyclone 2 having a high processing capacity, the fluid inlet 22 in the cyclone main body 21 extends along the inner wall of the introduction container 3 and the cyclone main body 21 It is sufficient to introduce a large number of objects to be processed into the cyclone 2 and to process a large number of objects to be processed in the cyclone 2, and on the contrary, when processing a fluid having a high content of the object to be processed or using a cyclone 2 having a low processing capacity. In this case, the fluid introduction port 22 in the cyclone main body 21 is positioned closer to the center side than the inner wall of the introduction container, and a large amount of the object to be processed is processed in the introduction container 3.

  In this embodiment, the position of the fluid inlet 22 is not fixed, and as shown in FIG. 7 (transmission diagram when the cyclone device 1 according to this embodiment is viewed from above (the discharge pipe 23 side)), The position of the fluid introduction port 22 in the introduction container 3 can be arbitrarily or arbitrarily changed according to the amount of the object to be processed in the fluid, and by configuring in this way, It is possible to cope with any change in the content of the object to be processed.

  FIG. 8 is a schematic view showing the device 1 of the present invention according to the fourth embodiment. By showing the introduction container 3 in a transmissive state, the inside of the introduction container 3 can be visually confirmed.

  The device 1 of the present invention according to the present embodiment is composed of a cyclone 2, an introduction container 3 and an introduction tube 4, and the circumference of the cyclone main body 21 is surrounded by the substantially cylindrical introduction container 3.

  The substantially cylindrical introduction container 3 used in the present embodiment is configured such that the inner diameter of the introduction container 3 gradually decreases from the bottom surface toward the ceiling surface. The swirling speed of the fluid introduced from the introduction pipe 4 into the introduction container 3 can be accelerated until it reaches the fluid introduction port 22 in the cyclone, and sufficient centrifugal force is applied to the workpiece in the fluid. And the speed of introduction of the fluid into the cyclone body 21 can be increased.

  Further, in this embodiment, since the inner diameter of the introduction container 3 is configured to decrease stepwise from the bottom surface toward the ceiling surface, each step in the introduction container 3 serves as a barrier, It becomes difficult for the object to be processed to exceed each stage in the introduction container 3, and the roughing efficiency in the introduction container 3 is further improved.

  FIG. 9 is a schematic view showing the device 1 of the present invention according to the fifth embodiment. By showing the introduction container 3 in a transmissive state, the inside of the introduction container 3 can be visually recognized.

  The inventive device 1 according to this embodiment includes a cyclone 2, a substantially cylindrical introduction container 3 and an introduction pipe 4. In particular, the inside of the introduction container 3 is partitioned by a partition plate 7 and a bypass passage 71 is provided in the partition plate. Is provided.

  That is, the device 1 of the present invention according to this embodiment is configured such that the introduction container is divided into two chambers 3a and 3b by the partition plate 7, and the object to be processed in the fluid is roughly removed in each of the chambers 3a and 3b. Therefore, the processing efficiency of the entire cyclone device can be improved.

  In addition, the movement of the fluid from the room 3a to the room 3b is performed through the bypass passage 71 provided in the partition plate 7. In this embodiment, the bypass passage 71 is given a swiveling motion in the room 3a. The fluid is made to flow out from the tangential direction and to flow in from the tangential direction toward the inner wall of the room 3b.

  Therefore, in this embodiment, the fluid in a state where the distribution of the object to be processed in the fluid is biased toward the inner wall of the room 3a is introduced into the room 3b as it is, and then in the room 3b, The fluid in which the distribution of the object to be processed is biased toward the inner wall of the room 3b can be introduced into the cyclone main body 21 as it is.

  In the present embodiment, the introduction speed of the fluid can also be controlled by providing differences in the radial cross-sectional areas of the introduction pipe 4, the bypass passage 71 and the fluid introduction port 22.

  FIG. 10 is a schematic view showing the device 1 of the present invention according to the sixth embodiment. By showing the introduction container 3 in a transmissive state, the inside of the introduction container 3 can be visually confirmed.

  The device 1 of the present invention according to the present embodiment is composed of a cyclone 2, an introduction container 3 and an introduction tube 4, and the circumference of the cyclone main body 21 is surrounded by the substantially cylindrical introduction container 3.

  The substantially cylindrical introduction container 3 used in the present embodiment is configured such that the inner diameter of the introduction container 3 gradually decreases from the bottom surface toward the ceiling surface, and is further introduced at each stage. The container 3 is partitioned by a partition plate 7 (7a, 7b) and a bypass passage 71 (71a, 71b) is provided in the partition plate.

  That is, the device 1 of the present invention according to the present embodiment is configured by dividing the introduction container 3 into three rooms 3a, 3b, 3c by the partition plates 7 (7a, 7b). Since the object to be processed in the fluid is roughly removed, the processing efficiency of the entire cyclone apparatus can be improved.

  In addition, the substantially cylindrical introduction container 3 used in the present embodiment is configured such that the inner diameter of the introduction container 3 gradually decreases from the bottom surface toward the ceiling surface. The swirling speed of the fluid introduced from the introduction pipe 4 into the introduction container 3 can be accelerated until it reaches the fluid introduction port 22 in the cyclone, and sufficient centrifugal force is applied to the workpiece in the fluid.
