Description

Device for removing impurities in bio gas

The present invention relates to a device for removing impurities from digestion gas generated in an anaerobic digester for biological treatment of wastewater, and more particularly, a state in which impurities contained in digestion gas are removed by receiving digestion gas generated in the digester. It relates to a device for removing impurities from extinguishing gas that can be transferred to a gas treatment device, which is the next process.

In general, the treatment of high-concentration organic wastes such as food waste, sewage sludge, wastewater sludge, agricultural waste, livestock manure, etc., which are generated in large quantities as material life becomes prosperous with industrial development, is roughly classified as incineration, landfill, and recycling. It can be divided into technology, and recycling technology is divided into feed and composting.

First of all, incineration of organic wastes requires that organic wastes contain a large amount of moisture and must be pretreated before incineration to remove moisture from organic wastes or to incinerate after lowering the moisture content. There is an increasing problem, and there is a serious problem that causes secondary environmental pollution due to the generation of dioxins due to incomplete combustion due to low calorific value and moisture content.

And, in the case of landfilling of organic waste, it is a matter that is prohibited nationally in terms of secondary pollution of the soil by the leachate of the buried organic waste while generating odor, and in terms of efficient use of limited land and waste of recyclable resources. to be.

In addition, as a recycling technology, feed conversion is the most popular technology from the viewpoint of recycling of resources, but it is a technology that requires very strict procedures in the processing process, and there are many problems recently. Composting has an aerobic method and an anaerobic method, but the aerobic method is aerobic microorganisms. It requires the use of moisture regulators (sawdust, etc.) to facilitate the breathing of the body, so economical efficiency is low and there is a drawback of causing problems in the atmosphere, whereas the anaerobic treatment method is blocked from the atmosphere to solve the odor problem as well as anaerobic treatment. Biogas (about 70% of methane) is generated during the process, which has an advantage in terms of energy use.

In more detail with respect to biogas, technologies related to the utilization of energy resources using organic wastes have been continuously developed in recent years, and an example is a method of producing biogas by anaerobic digestion of organic wastes.

This can be used by converting the produced biogas into electricity and thermal energy, and since it can be used as fertilizer as a by-product, its utilization is high and continuous development is required.

In particular, as part of the process of converting food waste into resources, research on recycling food waste into methane gas as a resource, i.e., anaerobic digestion, is being actively conducted. Anaerobic digestion refers to various complex symbiotic microbial communities that are anaerobic. It is the process of decomposing organic substances into methane and carbon dioxide in the state.

Theoretically, about 90% of biodegradable organic matter in the waste can be converted to methane. Moreover, the sludge generated after the anaerobic digestion process by stabilizing organic waste does not pose any environmental harm to the soil and water. Since it can be used as a fertilizer, another energy saving is possible.

In addition, methane, a major component of biogas, is a flexible type of renewable energy that can be converted into heat and electricity, and can be used as fuel for vehicles.

On the other hand, scum, an impurity generated in the digester, is known to occur when an imbalance in digestion occurs due to overloading of organic matter in the digester, a sudden decrease in temperature, improper agitation in the digester, and the introduction of poisons or heavy metals. , It reduces the effective capacity in the digester, and at the same time causes the problem of inhibiting the upper movement for the discharge of the digestion gas.In the event of excessive scum, it enters the passage of the digestive gas and obstructs the movement of the digestive gas or blocks the passage of the digestive gas. Since it is completely closed, it causes a problem that prevents the movement of the extinguishing gas, so it is essential to remove the scum properly.

As a conventional technique for appropriate removal of such scum, a scum layer formed in the gas-liquid boundary layer of the anaerobic digestion tank while being installed on the stirring shaft inside the anaerobic digestion tank in Korean Patent Application Publication No. 2010-0112430 (20101019) Disclosed is a scum removal device including a scum pulverization unit for pulverizing and a discharge unit through which the scum pulverized by the scum pulverization unit is introduced and discharged to the outside of an anaerobic digester.

However, in the past, scum is not effectively removed, and part of the scum gradually accumulates inside the connecting pipe in the process of moving along the connecting pipe along with the extinguishing gas, eventually preventing the movement of the extinguishing gas, and some scum passes through the connecting pipe. Therefore, there is a problem in that it affects the digestion gas storage tank and gas treatment equipment such as a desulfurization facility or a dehumidification device.

In addition, throughout the specification, when a certain part "includes" a certain component, this means that other components may be further included, not excluding other components unless otherwise stated.

Hereinafter, the configuration of the present invention will be described in more detail with reference to the illustrated drawings.

First, the apparatus for removing impurities from extinguishing gas according to the present invention includes a body connected to the digester, a gas inlet pipe provided on one side of the body part, a gas discharge pipe provided on the other side of the body part, and installed inside the body part. An impurity detection unit that detects impurities in the extinguishing gas flowing through the gas inlet pipe, and a water spray unit installed inside the body to remove impurities from the extinguishing gas by spraying water into the extinguishing gas when impurities in the extinguishing gas are detected. And a trap portion installed under the body portion, and each configuration will be described in detail with reference to the illustrated drawings below.

First, the body portion 100,

It is connected to the digester of an anaerobic digester for biological treatment of wastewater, and provides a space for temporarily storing digestion gas flowing from the digester.

The body portion 100 may be in the shape of a cylindrical tank having a closed space so that pressure can be maintained, and may be preferably configured to have a predetermined height, and the height is preferably approximately 5 m.

Here, the height of the body portion 100 need not be set to 5m, may be configured to be lower or higher than 5m, the inner diameter of the body portion 100 may also be configured in various ways according to the configured height.

The lower part of the body part 100 is provided with a trap part 600, which will be described later, so that water used to remove impurities contained in the extinguishing gas and impurities separated from the extinguishing gas can be discharged to the outside together. The lower portion of the body portion 100 may have a conical shape whose inner diameter gradually decreases toward the bottom so that excess impurities can be effectively discharged to the outside through the trap portion 600.

Meanwhile, at least one partition wall 110 and 120 may be provided inside the body part 100 so that impurities contained in the extinguishing gas can be separated from the extinguishing gas while delaying the movement of the introduced extinguishing gas.

The partition walls 110 and 120 are formed to protrude from one inner surface of the body part 100 in a direction perpendicular to the longitudinal direction, and are spaced apart from the other inner surface of the body part 100 facing the protruding end and the passage 111 (121) is formed, and the extinguishing gas is moved through these passages (111, 121).

Therefore, when the extinguishing gas is moved inside the body part 100, it moves while making contact along the back surface of the partitions 110 and 120, and then exits through the passages 111 and 121, and thus the extinguishing gas is Impurities contained in the extinguishing gas may be separated from the extinguishing gas in the process of making contact with the rear surfaces of the partition walls 110 and 120.

Preferably, the protruding end of the partition wall 110, 120, which is spaced apart from the other inner surface of the body portion 100 to form the passage 111, 121, is inclined downward to form the inclined portion 110a, 120a. By constituting, the fire extinguishing gas moving toward the passages 111 and 121 along the back surface of the partition walls 110 and 120 sufficiently contacts the inclined portions 110a and 120a and then exits through the passages 111 and 121 Therefore, when impurities contained in the extinguishing gas are separated while being moved along the rear surfaces of the partition walls 110 and 120, they can be intensively separated from the inclined portions 110a and 120a.

In addition, impurities separated from the inclined portions 110a and 120a do not remain in the inclined portions 110a and 120a as they are, and flow down along the inclined portions 110a and 120a and fall downward, so that the inclined portions 110a ) It is possible to prevent a phenomenon in which the passages 111 and 121 are blocked by impurities as impurities remain and accumulate in 120a.

In addition, as another embodiment, the partition walls 110 and 120 may be configured to be inclined downward by a predetermined angle rather than horizontally, and when the partition walls 110 and 120 are configured to be inclined, the extinguishing gas is transferred to the partition walls 110 and 120 120) can be moved with sufficient and maximal contact with the back surface, so that impurities contained in the extinguishing gas can be removed more effectively.

In the present invention, as a preferred embodiment of the partition walls 110 and 120, the first partition wall 110 and the second partition wall 120 spaced apart from each other are installed in a two-stage structure, and the second partition wall 120 is a body part 100 ) Is installed to be spaced a predetermined distance downward from the upper surface of the first partition wall 110, the first partition wall 110 is installed to be spaced a predetermined distance downward from the second partition wall 120, and the upper surface of the body portion 100 and the second partition wall 120 The distance between the two partitions and the distance between the second partition wall 120 and the first partition wall 110 need not be determined by any one, but the design conditions of the body part 100 or the amount and movement speed of the extinguishing gas flowing into the body part 100 It can be designed in various forms in consideration of the like.

Although not illustrated in the drawings, the partition walls 110 and 120 are installed to be movable along the inner surface of the body portion 100 by installing either or both of the first partition wall 110 or the second partition wall 120 as another example, In consideration of the amount or movement speed of the extinguishing gas introduced into the interior, the distance between each other may be configured to be simply adjusted while forming various combinations.

When the partition walls 110 and 120 are composed of the first partition wall 110 and the second partition wall 120, the first passage 111 and the second partition wall 120 formed on one side of the first partition wall 110 Although the second passage 121 formed on one side of the may be configured to be located on the same line, preferably the first passage 111 and the second passage 121 are located in opposite directions, not on the same line. By configuring to be in a state, the fire extinguishing gas passing through the first passage 111 of the first partition wall 110 does not directly escape to the second passage 121 of the second partition wall 120 It is preferable that it is configured to move while making maximum contact with the rear surface and then exit through the second passage 121.

In addition, if necessary, repeated unevenness or a plurality of grooves may be provided on the rear surfaces of the barrier ribs 110 and 120 through which the extinguishing gas is moved to further increase the contact area with the extinguishing gas.

On the other hand, at least one bypass pipe 130 connected to the inside of the body portion 100 from the outside of the body portion 100 may be installed in the body portion 100, and the bypass pipe 130 contains impurities. When the removed extinguishing gas is moved inside the body part 100, if it is stagnant or clogged in a specific section, a problem may occur in the internal pressure of the body part 100, so this is to solve this.

That is, after the extinguishing gas introduced into the body part 100 passes through the first passage 111 of the first partition 110, it moves along the surface of the second partition wall 120, and then moves along the second passage 121 When discharged to the outside of the body portion 100 through the passage, if impurities separated from the digestive gas gradually accumulate in the second passage 121, the second passage 121 eventually becomes a state in which the second passage 121 is blocked by the impurities. ), it may be difficult to control the internal pressure, and this problem can be solved through the bypass pipe 130.

The bypass pipe 130 is installed outside the body part 100 as an example, and the upper end of the bypass pipe 130 is the point where the second partition wall 120 is installed from the outside of the body part 100 and the body part ( It penetrates at any one point between the upper surface of 100) and is connected to the inner space of the body part 100, and the lower end of the bypass pipe 130 is at the point where the second partition wall 120 is installed from the outside of the body part 100 By penetrating at any one point between the points where the first partition wall 110 is installed and connected to the inner space of the body part 100, the first passage of the first partition wall 110 is blocked even if the second passage 121 is blocked by impurities. As the extinguishing gas passing through 111 passes through the second partition wall 120 through the bypass pipe 130 and is discharged to the outside of the body part 100, the internal pressure of the body part 100 is adjusted and the extinguishing gas Can be easily discharged.

The gas inlet pipe 200,

It is a means for introducing the extinguishing gas generated from the digester into the interior of the body portion 100 described above.

The gas inlet pipe 200 may be a tube shape having a substantially straight shape and a predetermined length, and the upper side is connected to the digester, and the lower side passes through the upper surface of the body part 100 to It can be configured to extend to one point.

The gas inlet pipe 200 is preferably installed through the upper surface of the body portion 100 through the center, and at this time, the lower side positioned inside the body portion 100 is the second partition wall 120 and the first partition wall 110 ), and the lower end outlet of the gas inlet pipe 200 that penetrates through the first partition wall 110 is formed to be inclined or configured in the form of an expansion pipe for effective discharge of the extinguishing gas, or in a specific direction. A guide may be provided to be guided.

Accordingly, the extinguishing gas discharged from the lower side of the gas inlet pipe 200 descends to some extent and then rises again, and the first passage 111 of the first partition 110 and the second passage 121 of the second partition 120 It is discharged to the outside of the body portion 100 through.

The gas discharge pipe 300,

It is a means for discharging the extinguishing gas from which impurities are removed from the inside of the body part 100 to the outside of the body part 100 and moving it to a gas treatment device such as a desulfurization device or a dehumidifying device, which is a subsequent process.

The gas discharge pipe 300 has one side passing through the upper surface of the body part 100 and its end is located inside the body part 100, and the other side is connected to the gas treatment device through a connection pipe or the like.

One end of the gas discharge pipe is located at a point spaced apart from the surface of the second partition wall 120 so as not to interfere with the second partition wall 120 inside the body part 100, and the second passage of the second partition wall 120 It is preferably located on the same line as (121).

Here, it is obvious that the position, length, inner diameter, and material of the gas inlet pipe 200 and the gas outlet pipe 300 described above do not need to be set to any one, and may be modified in various forms depending on the extinguishing gas to be treated. .

The impurity detection unit 400,

It is a means for determining whether impurities are contained in the digestion gas introduced into the body part 100.

When the extinguishing gas contains impurities in the process of contacting the extinguishing gas, the impurity detection unit 400 detects impurities contained in the extinguishing gas on the surface of the impurity detection unit 400 and the extinguishing gas contains impurities. To the control unit.

The impurity detection unit 400 may be configured as a sensing device such as a sensor that can effectively determine impurities according to the type of impurity, and is located at the lower end of the gas inlet pipe 200 to effectively detect impurities in the extinguishing gas. It is preferable to be installed so as to be adjacent.

For example, the impurity detection unit 400 is adjacent to the lower end of the gas inlet pipe 200, but is installed horizontally while maintaining a right angle with respect to the inner surface of the body portion 100, so that at the lower end of the gas inlet pipe 200 The exhausted extinguishing gas can effectively contact the surface of the impurity detection unit 400

The control unit connected to the impurity detection unit 400 determines whether there are impurities contained in the extinguishing gas through the impurity detection unit 400, and then controls the water spraying unit 500 to be described later to remove the impurities included in the extinguishing gas. .

The water spray unit 500,

When the extinguishing gas contains impurities, it is a means for separating the impurities contained in the extinguishing gas from the extinguishing gas by injecting a predetermined amount of water toward the extinguishing gas at a predetermined speed.

The water spray part 500 is installed inside the body part 100, and is formed on the outer circumference of the water supply pipe 510 to which water is supplied from the outside of the body part 100 and to the outside. It may be configured to include a spray nozzle 520 to spray water.

The water spraying unit 500 is connected to the above-described control unit, and when the control unit determines that the extinguishing gas contains impurities by receiving the signal from the impurity detection unit 400, the control unit operates the water spraying unit 500 to spray water. By supplying water to the water supply pipe 510 of the thread part 500, water is sprayed from the spray nozzle 520 provided in the water supply pipe 510.

For example, the water spray unit 500 is installed adjacent to the lower side of the impurity detection unit 400, and is installed horizontally while maintaining a right angle with respect to the inner surface of the body 100 so as to be parallel to the impurity detection unit 400. As a result, when the extinguishing gas containing impurities discharged from the lower end of the gas inlet pipe 200 comes into contact with the impurity detection unit 400 and then is directed to the water spraying unit 500, the signal of the impurity detection unit 400 As the control unit receives the water injection unit 500 immediately operates, the water of the water injection unit 500 is sprayed vertically or vertically, left and right, and impurities contained in the extinguishing gas may be separated from the extinguishing gas by the sprayed water.

The spray nozzle 520 formed on the outer circumference of the water spraying part 500 may be at least one or more, preferably forming a radial shape along the outer circumference of the water supply pipe 510 and along the longitudinal direction of the water supply pipe 510 It can be installed in multiple spaced apart.

Here, the spray nozzle 520 formed in the water supply pipe 510 may be variously modified and implemented without the need to set the spray amount, spray angle, installation position or number of water to any one.

The trap part 600,

It is a means for temporarily storing impurities separated from the extinguishing gas introduced into the body part 100 by being installed under the body part 100 and water used in the process of removing these impurities and then discharging them to the outside. .

One side of the trap part 600 is installed on the bottom surface of the body part 100 and connected through the body part 100, and the other side is formed by being bent in a U shape, and the other side removes impurities and such impurities. A discharge port 610 is provided so that the water used in the process of being discharged can be discharged together.

Therefore, impurities and used water remain filled in the trap part 600 to some extent, and when impurities and used water are added to the lower part of the body part 100, the existing impurities and used water are discharged as much as the added amount. By being discharged through the 610, the trap part 600 always maintains a state in which a certain amount of impurities and used water are stored, and the internal pressure of the body part 100 is maintained through the trap part 600. It can be.

Meanwhile, an overflow part 620 may be provided at the other end of the trap part 600. When a problem occurs in the discharge port 610, the overflow part 620 is used in the process of removing impurities and impurities. Used water is to be discharged through the overflow unit 620, and the water used together with impurities is always stored inside the trap unit 600, so that the internal pressure of the body unit 100 can be maintained. Therefore, when water is insufficient in the trap unit 600, water can be automatically or manually supplied through the overflow unit 620 to fill water in the trap unit 600.

Looking at the process of removing the impurities of the extinguishing gas through the impurity removal apparatus of the extinguishing gas of the present invention configured as described above,

First, in the apparatus for removing impurities according to the present invention, the upper side of the gas inlet pipe 200 drawn out from one upper surface of the body portion 100 is connected to the digester, and the upper side of the upper surface of the body portion 100 is drawn out to the outside. The upper side of the gas discharge pipe 300 is configured to be connected to a gas processing device which is a subsequent process.

Therefore, the extinguishing gas generated from the digester is introduced into the body part 100 through the gas inlet pipe 200, and the extinguishing gas discharged from the lower end of the gas inlet pipe 200 is lower than the gas inlet pipe 200. It comes into contact with the impurity detection unit 400 installed adjacent to the end.

If the impurity detection unit 400 does not detect the impurity while the extinguishing gas contacts the impurity detection unit 400, it is determined that the impurity does not exist in the extinguishing gas and the water spray unit 500 is not operated, The gas rises and is moved to the gas treatment device through the gas discharge pipe 300.

At this time, the extinguishing gas is discharged to the first passage 111 through the back surface of the first partition wall 110, and then through the second passage 121 through the second passage 121 to the gas discharge pipe 300. It is moved, and impurities of the digestion gas that are not detected by the impurity detector 400 may be removed through contact with the rear surface of the first partition wall 110 and the rear surface of the second partition wall 120.

On the other hand, in the process that the extinguishing gas generated in the digester flows into the body part 100 through the gas inlet pipe 200 and contacts the impurity detection part 400, the impurities of the extinguishing gas When detected, the control unit immediately operates the water injection unit 500, and a predetermined amount of water is injected into the extinguishing gas through the injection nozzle 520 of the water injection unit 500, and thus impurities contained in the extinguishing gas are used. The extinguishing gas from which the impurities are removed passes through the back surface of the first partition wall 110 and passes through the first passage 111 and then passes through the back surface of the second partition wall 120. And is discharged to the gas discharge pipe 300 through the second passage 121, and at this time, the extinguishing gas remains in the extinguishing gas in the process of contacting the rear surfaces of the first and second partitions 110 and 120. Possible impurities may be removed.

In addition, impurities that have fallen to the lower part of the body part 100 along with the used water are gradually accumulated in the trap part 600, and the used water and impurities that have been previously stored as accumulated are automatically transferred to the outside through the discharge port 610. Is discharged.

Therefore, the extinguishing gas of the digester is moved to the gas treatment device which is a subsequent process from the state where the impurities contained therein are effectively removed during the process of passing through the impurity removal device. It is possible to prevent problems in advance.
