Description

The present invention relates to processing apparatus.

  It is desirable that the air deodorized by the deodorizing device is exhausted to the atmosphere without being mixed with the odor remaining air. For example, in a waste treatment apparatus that treats waste such as garbage, moisture (water vapor) removed from the waste is discharged as exhaust gas to the outside of the apparatus. It is exhausted after deodorizing. For deodorization, a deodorization apparatus including a catalyst such as an oxidation catalyst and a heater for heating air to a temperature suitable for the catalyst is usually used.

  Patent Document 1 discloses a garbage treatment device that includes a deodorization device, deodorizes the air in the treatment tank, and discharges the air outside the device. When the air heated by the heater of the deodorizing apparatus is exhausted, the heat energy is exhausted wastefully. Therefore, in the garbage disposal apparatus of Patent Document 1, a part of the air that has passed through the deodorizing apparatus is exhausted to the outside of the apparatus, and the rest is returned to the apparatus to be used for heating waste.

JP 2003-320358 A

  The air deodorized by the deodorizing device is not necessarily deodorized uniformly, and the degree of deodorization may vary depending on the discharge site. For example, in the case of using a catalyst such as an oxidation catalyst, heat is relatively high at the center of the catalyst and relatively low at the outer periphery due to heat radiation on the outer peripheral surface of the catalyst. For this reason, the catalyst is not sufficiently activated at the outer peripheral portion, and the air that has passed through the outer peripheral portion may not be sufficiently deodorized. As a result, the scented air may be exhausted to the atmosphere.

  An object of the present invention is to classify and exhaust air having different degrees of deodorization so that only air having a higher degree of deodorization is exhausted to the atmosphere.

According to the present invention, the treatment apparatus is a treatment tank that heats the object to be treated, a heater part to which air in the treatment tank is supplied, and an inlet to which air that has passed through the heater part is introduced. And a deodorizing part for deodorizing air passing from the inlet part to the outlet part, and air discharged from the outlet part. First exhaust that communicates with the part of the outlet part and exhausts the air out of the processing apparatus so that only the air discharged from the part of the outlet part having a relatively high temperature is introduced. Of the air exhausted from the passage and the outlet part, the part is a part other than a part of the outlet part, and is exhausted from another part having a relatively lower temperature than the part of the outlet part. In communication with the other part of the outlet, so that all air is introduced, Comprising a second exhaust passage for recirculating air to serial processing bath, and the downstream side of the outlet portion, wherein the first exhaust passage and the second exhaust passage, the second exhaust passage of the first exhaust There is provided a processing apparatus characterized by having a double pipe structure surrounding a passage .

  According to the present invention, air having different degrees of deodorization can be classified and exhausted so that only air having a higher degree of deodorization is exhausted to the atmosphere.

In the figure, the arrow Z indicates the vertical direction (the height direction of the processing apparatus A), the arrows X and Y are orthogonal to each other (the X direction is the width direction of the processing apparatus A, and the Y direction is the depth direction of the processing apparatus A). ). The processing device A is a waste processing device that treats waste such as garbage as a processing target and reduces the amount thereof.

<Outline of device>
As shown in FIG. 1, a door 1 for opening and closing a loading port 1a for loading garbage is rotatably provided on the upper surface of the processing apparatus A. When the door 1 is closed, a sealing member (not shown) is provided around the door 1 so that the inside of the processing apparatus A is kept airtight.

  An operation unit 3 is provided in front of the processing apparatus A. The operation unit 3 is provided with a lamp or the like for the user to instruct the processing apparatus A to start and stop processing. Further, a discharge port 2 for discharging the processing object that has been subjected to the weight reduction process, and a door 2a for opening and closing the discharge port 2 are rotatably provided.

  Referring to FIG. 2, processing apparatus A includes a bottom plate 4, and a caster 5 is attached to the lower surface of the processing apparatus A to facilitate the movement of processing apparatus A. On the bottom plate 4, partition walls 6 to 8 spaced from each other in the X direction are provided upright in the Z direction. The partition walls 6 to 8 are fixed to the bottom plate 4 and are partition walls that partition the processing apparatus A. In the processing apparatus A, for example, waste such as garbage is heated as a processing target. In detail, it is a weight reduction process of the processing target object by the fermentation process used as the pre-processing of a processing target object, and the drying process used as a post-process.

  The space between the partition wall 6 and the partition wall 7 forms the first processing tank 10, and the space between the partition wall 7 and the partition wall 8 forms the second processing tank 11, and continues in the X direction. These disposed first treatment tank 10 and second treatment tank 11 constitute a treatment tank for reducing garbage. In addition, in this embodiment, although the processing tank is divided roughly and it is set as 2 tank structure, it is good also divided and it is good also as a structure of 3 tanks or more.

  A storage tank 12 partitioned by a partition wall 8 is formed on the side of the second processing tank 11 in the X direction. The storage tank 12 is introduced from the second processing tank 11 with the processing object subjected to the weight reduction process. The storage tank 12 communicates with the discharge port 2, and the processing object that has been subjected to the weight reduction process can be taken out from the storage tank 12 by opening the door 2 a.

  The processing apparatus A includes a drive unit 20. The drive unit 20 includes a drive shaft 21 that traverses the first treatment tank 10 and the second treatment tank 11. The drive shaft 21 extends in the X direction and is rotatably supported by bearings 22 provided on the partition walls 6 to 8 respectively. The drive unit 20 also includes a sprocket 23 fixed to one end portion of the drive shaft 21 and a motor 24. A belt transmission mechanism is configured by winding a belt around the sprocket 23 and a sprocket fixed to the output shaft of the motor 24. The drive shaft 21 is rotated by driving the motor 24.

  In the first treatment tank 10, a plurality of stirring rods 25 extending in the radial direction are attached to the drive shaft 21. Due to the rotation of the drive shaft 21, the processing object in the first processing tank 10 and the second processing tank 11 is stirred by the stirring rod 25. A communication hole 71 for communicating the first processing tank 10 and the second processing tank 11 is formed below the partition wall 7, and the first processing tank 10 to the second processing tank 11 are stirred by the stirring rod 25. The object to be processed is movable.

  The object to be treated in the second treatment tank 11 falls over the partition wall 8 to the storage tank 12 due to an increase in the amount of deposition, and accumulates in the storage tank 12. In the present embodiment, the processing object can be moved from the second processing tank 11 to the storage tank 12 beyond the partition wall 8, but other methods can also be adopted. For example, the processing object may be movable by providing a communication hole (communication part) in the lower part of the partition wall 8 and underflowing the processing object from the second processing tank 11 to the storage tank 12.

  The first treatment tank 10 is provided with a blower 35. The blower 35 sucks and blows air in the first processing tank 10 in a direction indicated by an arrow in FIG. 2 to circulate the air in the first processing tank 10. In the upper space of the storage tank 12 and the second treatment tank 11, a deodorizing device 100 accommodated in the case member 30 is disposed. The case member 30 has a box shape, and air from the blower 31 is introduced into the inside. The introduced air passes through the outer peripheral portion of the passage of the air deodorized by the deodorizing apparatus 100 described later. Therefore, the introduced air is heated by exchanging heat with the heat-deodorized air.

  The blower 31 sucks the air in the treatment tank 10 through the duct 31 a passing through the partition wall 7 and blows it into the case member 30. The air heated in advance by heat exchange blown into the case member 30 is introduced into the deodorizing apparatus 100 from the introduction port 104 c of the deodorizing apparatus 100. Thereby, the air in the processing tank 10 is supplied to the heater unit 101 of the deodorizing apparatus 100. Since the supplied air is preheated by heat exchange, the load on the heater unit 101 can be reduced. The deodorizing apparatus 100 will be described with reference to FIG. 3A in addition to FIG. FIG. 3 (A) is an explanatory view of the deodorizing apparatus 100, and shows an outline thereof in a perspective view.

  The deodorizing apparatus 100 includes a heater unit 101 and a deodorizing unit 102, which are arranged in the X direction within the case member 104. The air introduced into the case member 104 from the introduction port 104c passes through the heater part 101 and the deodorizing part 102 in this order, and is deodorized. In the case of the present embodiment, the deodorizing unit 102 is made of a catalyst such as an oxidation catalyst carrying platinum, and the heater unit 101 uses the air introduced into the case member 104 from the introduction port 104c to the activation temperature of the deodorizing unit 102. Warm up.

  The configuration of the heater unit 101 may be any configuration as long as air can be heated, but in the present embodiment, the following configuration is adopted. 4A and 4B are explanatory views of the heater unit 101, FIG. 4A shows a cross-sectional structure of the heater unit 101, and FIG. 4B shows a line II in FIG. 4A. FIG.

  In the case of this embodiment, the heater unit 101 includes a heater element 101a in which a linear heating element is formed in a spiral shape. The heater element 101a is disposed so as to surround a central portion RT of an air passage defined by the case member 104. Further, the end of the case member 104 on the introduction port 104c side, which serves as the inlet of the heater part 101, has a guide part 104b. The introduction port 104c is formed correspondingly. Thereby, the air outside the case member 104 can be efficiently heated by the heater unit 101.

  The guide part 104b prevents air from passing through the outside of the heater element 101a and reaching the deodorizing part 102 without being sufficiently heated, as indicated by an arrow d2. Due to the presence of the guide portion 104b, the air in the case member 30 is guided to the central portion RT and passes between the heater portions 101 while contacting the heater element 101a from the inside to the outside of the heater element 101a as indicated by an arrow d1. Become.

  As a result, the air passing through the heater unit 101 is more reliably heated, and the temperature distribution of the air discharged from the heater unit 101 can be made more uniform by generating turbulent flow during mixing and mixing. This is useful for improving the degree of deodorization by heating the entire air introduced into the deodorization unit 102 to the activation temperature. For the purpose of positively generating turbulent flow, a turbulent flow generation plate that disturbs the airflow and stirs may be provided inside the heater unit 101.

  In the present embodiment, the heater element 101a is formed in a spiral shape, but the shape is not limited thereto. For example, a plurality of heater elements formed in an annular shape are arranged at a predetermined distance from the wall surface of the case member 104, such as by arranging them in the airflow direction, so that air can pass through the inside. What is necessary is just to be comprised.

  Returning to FIG. 2 and FIG. 3 (A), the deodorizing apparatus 100 will be further described. The deodorization part 102 has the inlet part 102a in which the air which passed the heater part 101 is introduce | transduced, and the outlet part 102b of the other side from which the air introduced in the inlet part is discharged | emitted. In the present embodiment, the inlet portion 102a and the outlet portion 102b are both flat, and the deodorizing portion 102 has a rectangular parallelepiped shape.

  The air discharged from the outlet portion 102b of the deodorizing unit 102 is introduced into either the discharge passage 103a or the discharge passage 104a. The exhaust passage 103a is formed by a tubular duct member 103, and communicates with a part of the air exhausted from the outlet part 102b so that only the air exhausted from a part of the outlet part 102b is introduced. ing. In the present embodiment, the exhaust passage 103a communicates with the central portion of the outlet portion 102b. The communication between the exhaust passage 103a and the outlet portion 102b may be realized by airtightly contacting the end portion of the tubular member 103 with the outlet portion 102b, or may be realized by fixing the airtightly.

  The exhaust passage 104a is formed by the case member 104, and communicates with the other part of the outlet part 102b so that air discharged from other parts other than a part (center part) of the outlet part 102b is introduced. In this embodiment, the exhaust passage 104a is formed by the case member 104, but another duct member may be provided. However, cost reduction can be achieved by using a structure in which the case member 104 serves as the case of the deodorizing apparatus 100 and the duct of the exhaust passage 104a.

  In the case of this embodiment, in the deodorizing apparatus 100, the duct member 103 and the case member 104 have a double-pipe structure on the downstream side of the deodorizing unit 102. Only the air discharged from the central portion of the outlet portion 102b is introduced into the discharge passage 103a, and the air discharged from the remaining portion of the outlet portion 102b is introduced into the discharge passage 104a. The advantages are as follows.

  When air passes through the deodorizing unit 102, the temperature distribution near the outlet of the deodorizing unit 102 is relatively high at the center of the deodorizing unit 102 due to heat radiation from the outer peripheral surface of the deodorizing unit 102, and the temperature decreases as the outer periphery is reached Tend to. That is, in the vicinity of the central portion where the temperature is relatively high, the activation temperature is maintained and a sufficient deodorizing effect is obtained, so that the air introduced into the exhaust passage 103a is introduced with air having a high degree of deodorization. Become.

  On the other hand, since the air introduced into the exhaust passage 104a is air in a portion excluding the central portion of the deodorizing portion 102, the activation temperature of the deodorizing portion 102 cannot be maintained due to the temperature drop, and the odor cannot be completely removed. May be included. Since the exhaust passage 103a and the exhaust passage 104a are each configured as an independent passage, the air introduced into the exhaust passage 103a may be mixed with air that has a clear smell in the exhaust passage 104a. Absent. Thus, in the present embodiment, air having different degrees of deodorization can be classified and exhausted or recirculated.

  In the present embodiment, the exhaust passage 103a is communicated with the central portion of the outlet portion 102b. However, the communicating portion is not limited to the central portion, and may be other portions as long as the degree of deodorization is high. For example, if it is a site | part with a high deodorizing degree, as shown to FIG. 3 (B), the corner vicinity of the exit part 102b may be sufficient. Further, a configuration other than the catalyst can be employed as the deodorizing unit 102.

  In the case of this embodiment, the air introduced into the exhaust passage 103 a is sucked by the blower 33 and exhausted to the outside of the processing apparatus A through the duct 33 a and the ventilation hole 34. That is, the exhaust passage 103a is a first exhaust passage for exhausting air out of the processing apparatus A. Since only the deodorized air can be exhausted to the atmosphere outside the processing apparatus A, it is possible to prevent a strange odor from drifting around the processing apparatus A.

  The processing tank 10, the processing tank 11, and the storage tank 12 are configured to maintain airtightness except for the ventilation hole 34, and outside air corresponding to the amount of air exhausted from the duct 33 a is passed through the ventilation hole 34 into the processing apparatus A. Naturally inhaled. Therefore, ventilation in the processing apparatus A is promoted, and a strange odor in the processing apparatus A is also reduced.

  Since the air introduced into the exhaust passage 104a is recirculated to the treatment tank 11, it remains in the treatment apparatus A, is circulated to the deodorization apparatus 100, and is deodorized again. That is, the exhaust passage 104a is a second exhaust passage for returning air to the inside of the processing apparatus A, particularly to the processing tank 11. The air recirculated from the exhaust passage 104a to the processing tank 11 is blown to the processing object RD2 in the processing tank 11, and the drying thereof is promoted. Furthermore, since the air in the exhaust path 104a is the air that has passed through the deodorizing unit 102, the odor in the atmosphere in the treatment tank can be reduced.

  In addition, a communication hole 72 that allows the processing tank 10 and the processing tank 11 to communicate with each other is formed in the upper part of the partition wall 7, and the air guided from the exhaust passage 104 a to the processing tank 11 passes through the communication hole 72. It flows into the tank 10. Thus, the heated and deodorized air is not exhausted, and is used for heating in the processing tank 10 and the processing tank 11, so that the heat energy of the heater unit 101 of the deodorizing apparatus 100 can be more effectively processed. It can also be used for heating treatment.

<Control unit>
FIG. 5 is a block diagram of the control unit 40 of the processing apparatus A. The control unit 40 includes a CPU 41, a ROM 42, a RAM 43, and an I / F (interface) 44. CPU41 acquires the operation state of the operation part 3 via I / F44, and controls the air blowers 31, 33, 35, the heater element 101a, and the motor 24. The ROM 42 stores control programs executed by the CPU 41 and data. The RAM 43 stores temporary data. The ROM 42 and RAM 43 may employ other types of storage means.

<Weight loss treatment>
A process for reducing waste such as garbage by the processing apparatus A will be described with reference to FIG. Known methods for reducing food waste include a method of simply dehydrating food waste, a method of drying food waste, and a decomposition treatment (fermentation treatment) using microorganisms. In the present embodiment, the weight loss process is a combination of the decomposition process and the drying process, but other methods may be used.

  The garbage thrown in from the loading port 1a enters the treatment tank 10 first. The processing object RD1 containing a large amount of moisture in the processing tank 10 is decomposed by the action of a base material that becomes a fungus bed such as microorganisms present in the processing object RD1 or pre-loaded large sawdust. At that time, the heated air exhausted from the exhaust passage 104a is introduced into the treatment tank 10 through the communication hole 72, whereby the inside of the treatment tank 10 is maintained at a temperature and humidity suitable for activating microorganisms. . Further, the uniform decomposition of the processing object RD1 is promoted by the stirring by the stirring rod 25 and the circulation of the air by the blower 35.

  Although the air in the processing tank 10 has a strange odor due to fermentation of the processing object RD1, it is deodorized by the deodorizing device 100 and exhausted to the outside of the processing device A, and the outside air naturally enters the processing device A from the ventilation hole 34. Since it is inhaled, the degree is reduced. Since the air exhausted to the atmosphere outside the processing apparatus A is only air having a high degree of deodorization, it is possible to prevent the generation of a strange odor around the place where the processing apparatus A is installed.

  The processing object RD <b> 1 in the processing tank 11, which has been reduced in weight as the decomposition process proceeds, moves from the processing tank 10 to the processing tank 11 through the communication hole 71 in the lower part of the partition wall 7. The processing object RD2 in the processing tank 11 is dried mainly by blowing heated air exhausted from the exhaust passage 104a. The processing object RD2 that has been dried and accumulated in the processing tank 11 overflows from the processing tank 11 and moves to the storage tank 12. Garbage residue RD3 generated by such weight reduction processing is accumulated in the storage tank 13.

  In addition, as in the embodiment of the present invention, when the air supplied to the heater unit is configured to be heated by heat exchange in advance with heat-deodorized air, the load on the heater unit is reduced and the air is exhausted out of the processing apparatus. Reduce the temperature of the air. That is, the possibility that the heat of the exhaust gas adversely affects the external environment can be reduced. On the other hand, a temperature drop tends to occur at the outer periphery of the catalyst. Therefore, the possibility of exhausting the odor to the outside can be further reduced by recirculating the air passing through the outer peripheral portion of the catalyst to the inside and discharging the air passing through the center portion to the outside.

  In the above-described embodiment, the waste processing apparatus that processes waste such as garbage is illustrated as an example of the processing target. However, the processing apparatus of the present invention is not limited to this, and for example, heat treatment The present invention can be applied to an apparatus, a stirring treatment device, a mixing treatment device, a reduction solution treatment device and the like. Moreover, the deodorizing apparatus of this invention can be utilized for various apparatuses other than a waste disposal apparatus.
