Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a deodorizing device and a waste treatment system.

[0002]

2. Description of the Related Art A deodorizing device is a device for deodorizing a gas containing an odor component to deodorize it. Some of the deodorizing devices perform heat exchange between the pretreatment gas before passing through the treatment section for performing the deodorization treatment and the posttreatment gas after passing through the treatment section. Since such a deodorizing device heats the untreated gas by the heat contained in the treated gas discharged from the deodorizing device, it is possible to effectively use the exhaust heat to save energy.

A waste treatment system is also used in which such a deodorizing device is combined with a waste treating device for treating wastes to deodorize a gas containing an odorous component generated when the wastes are treated by the deodorizing device. There is.

[0004]

On the other hand, in such a waste treatment system, when a gas containing an odorous component is sent to the deodorizing device, the components contained in this gas may condense to produce a liquid. is there. In the waste treatment system,
A liquid may be generated together with the gas containing the odorous component discharged from the waste treatment device. For example, in the garbage processing apparatus, water contained in the garbage is often released in order to reduce the amount of the garbage. In particular, in a microbial type garbage treatment device that decomposes garbage by the action of microorganisms, water may be generated even when the microorganisms decompose the garbage. Even if the generated liquid is vaporized and mixed with the gas to be deodorized, it may be condensed and appear as a liquid before being processed by the processing unit in the deodorization processing apparatus. Such liquid tends to obstruct the passage of the gas sent to the deodorizing device and hinder the sending of the gas to the deodorizing device. Further, in the waste treatment system, discharge of gas from the waste treatment apparatus is hindered, and a problem such as being unable to continue the treatment of the waste easily occurs.

An object of the present invention is to provide a deodorizing device and a waste treatment system capable of treating gas and liquid containing odorous components.

[0006]

According to a first aspect of the present invention, there is provided a deodorizing device for treating a gas and a liquid containing an odor component, which comprises a treating portion, a heating means, a heat exchange portion, and a liquid. And a charging section. The processing part is a part that has a processing means for processing the odorous component contained in the gas and allows the gas to pass therethrough. The heating means heats the processing means. The heat exchange unit causes heat exchange between the pre-treatment gas before passing through the treatment unit and the post-treatment gas after passing through the treatment unit. The liquid charging unit charges the liquid to the gas whose temperature has risen through the heat exchange unit.

In this deodorizing device, since the liquid charging unit charges the liquid to the gas whose temperature has passed through the heat exchange unit, the charged liquid receives heat from the gas and evaporates. In this way, the liquid evaporates and becomes a gas, and is discharged as a gas together with the gas that has passed through the heat exchange section. On the other hand, the gas containing the odor component is deodorized and discharged to the outside. A second aspect of the present invention is the deodorizing device according to the first aspect, wherein the liquid feeding unit feeds the liquid to the pretreatment gas before passing through the treatment unit.

In this deodorizing device, since the liquid is fed to the untreated gas before passing through the processing unit, the liquid is vaporized into a gas, and then passes through the processing unit and is deodorized by the processing means. For this reason, even when the liquid contains an odor component and the odor component remains after vaporization, the odor component is deodorized, and the possibility of the bad odor of the discharged gas becoming a problem becomes smaller.

According to a third aspect of the present invention, there is provided a waste treatment system including a waste treatment device for treating waste and a deodorizing device. The deodorizing device is the deodorizing device according to claim 1 or 2, which deodorizes gas and liquid containing an odor component discharged from the waste treatment device. In a waste treatment device for treating waste, a bad smell generated when treating the waste becomes a problem. Since this waste treatment system includes the waste treatment device and the deodorizing device, the waste treatment device can treat the waste and the odorous gas and liquid generated when the waste is treated. In particular, even when a liquid is generated when treating the waste, the liquid can be evaporated and discharged from the deodorizing device to the outside together with the gas after the deodorizing treatment.

According to a fourth aspect of the present invention, there is provided a waste treatment system, wherein the waste treatment apparatus treats the waste, and
Alternatively, the deodorizing device described in 2 and the pipe are provided. The pipe is for sending the gas containing the odorous component discharged from the waste treatment device to the deodorizing device. The deodorizing device processes gas and liquid generated in piping. In the waste treatment device, when the waste is treated, it is often heated, and a warm gas is discharged. In addition, when liquid such as water contained in waste is processed, it may be released and contained in the discharged gas. In this case, when the discharged gas is sent to the deodorizing device through the pipe, the components contained in the gas may condense and a liquid may be generated in the pipe. This liquid clogs the piping, hinders the discharge of gas from the waste treatment device, and causes the waste treatment of the waste treatment device.

In this waste treatment system, the liquid generated in the pipe is introduced into the pretreatment gas before passing through the treatment section by the deodorizing device. Then, the liquid evaporates and becomes a gas and is discharged. Therefore, it is prevented that the liquid is generated in the pipe and the processing of the waste in the waste processing apparatus is hindered. The invention according to claim 5 is the waste treatment system according to claim 4, wherein the pipe is high on the waste treatment device side and low on the deodorization device side, and is continuously inclined.

In this waste treatment system, the pipe is high on the waste treatment device side and low on the deodorization device side, and since it is continuously inclined, the liquid generated in the pipe flows to the deodorization device side by gravity. It is processed by a deodorizing device.
Therefore, it is possible to prevent the liquid generated in the pipe from flowing to the waste treatment device side and hindering the discharge of gas from the waste treatment device.

The invention according to claim 6 is the invention according to claim 4 or 5.
In the waste treatment system described in (1), the pipe has a drain trap that discharges the drain to the liquid input unit of the deodorizing device. In this waste treatment system, the liquid generated in the pipe is stored in the drain trap and then treated by the deodorizing device. Therefore, it is possible to prevent the liquid generated in the pipe from flowing back to the waste treatment device side.

Is. [Operation and Characteristics of Raw Waste Processing System] The operation and characteristics of the raw garbage processing system 100 according to the present embodiment will be described mainly with reference to FIGS. 1 and 4.

First, in FIG. 1, when garbage is introduced into the processing chamber 10 of the garbage treating apparatus 1, the garbage is decomposed by the action of microorganisms. At this time, odorous gas containing various odorous components such as nitrogenous compounds such as ammonia, aldehydes such as acetaldehyde and isovaleraldehyde, and sulfur compounds such as hydrogen sulfide and methyl disulfide is generated. Also, water contained in raw garbage is released,
A large amount of water is contained in the derived odorous gas due to the generation of water during decomposition of garbage.

The generated gas passes through the exhaust path 12 and is discharged from the garbage processing device 1 to the pipe 3. In the raw garbage processing device 1, when the raw garbage is processed, heat treatment is performed in order to activate the microorganisms or release the moisture of the raw garbage, and the gas discharged is, for example, 30 The temperature is about 40 ° C. The gas discharged from the garbage disposal 1 passes through the pipe 3 and is sent to the deodorizer 2. At this time, the odorous gas passing through the pipe 3 is cooled, and the moisture contained in the odorous gas is condensed to generate drain water. By the way, since the heaters 84a and 84b for heating are provided in the deodorizing device 2, the temperature in the deodorizing device 2 is usually higher than that in the outside air. Therefore, drain water often occurs in the pipe 3 rather than in the deodorizer 2 having a high temperature. In this garbage processing system 100, since the pipe 3 is high on the garbage processing device 1 side and low on the deodorizing device 2 side, the drain water generated in the pipe 3 flows to the deodorizing device 2 side. Therefore, drain water flows into the garbage processing device 1 and the exhaust path 12 of the garbage processing device 1
Occurrence of defects that block the

As described above, the drain water generated in the pipe 3 and the odorous gas discharged from the garbage treatment device 1 are supplied from the air supply section 41 of the drain trap 4 to the drain trap body 40.
It flows in (see FIG. 3). Drain trap body 40
The odorous gas that has flowed in flows out through an exhaust unit 42 provided on the opposite side of the air supply unit 41. Then, the drain water is stored in the drain trap body 40. When the amount of drain water stored in the drain trap body 40 increases and the water level reaches the same height as the upper end of the drain pipe 6, the amount of drain water further increased from the state is the drain pipe 6
Is discharged inside.

The odorous gas flowing out from the exhaust portion 42 of the drain trap 4 is sent to the exhaust tower 7 by the air blower 5. In the exhaust tower 7, heat moves as indicated by the white arrow A1 in FIG. 4, and heat is generated between the pretreatment odor gas before passing through the catalyst heating chamber 81 and the posttreatment odor gas after passing through the catalyst heating chamber 81. Exchange will take place. The odorous gas flows from the second path R2 in the exhaust tower 7 into the gas path R3 in the deodorization processing unit section 8. At this time, the temperature of the odorous gas is heated by performing heat exchange, and is about 100 to 150 ° C. In addition, in FIG. 4, a solid arrow A2 represents the flow of the odorous gas.

The drain water stored in the drain trap body 40 flows from the drain trap body 40 through the drain pipe 6 into the gas path R3 in the deodorizing unit unit 8. That is, drain water is thrown into the odorous gas heated by heat exchange. Since the odorous gas has a high temperature of 100 degrees or more, the drain water evaporates and becomes a gas, which is mixed with the odorous gas. Note that FIG.
In, the dashed arrow A3 indicates the flow of drain water.

The mixed gas of the odorous gas and the evaporated drain water is sent to the catalyst heating chamber 81 through the gas path R3. The mixed gas sent to the catalyst heating chamber 81 is the catalyst 83 heated by the heaters 84a and 84b for heating.
When passing through a and 83b, the odorous components are oxidatively decomposed and deodorized. For this reason, even if the drain water contains an odorous component, it is deodorized by the catalysts 83a and 83b together with the odorous gas, so that the odor is prevented from flowing to the outside.

The mixed gas at this time is the catalyst 83.
It is heated by heaters 84a and 84b for heating a and 83b to a high temperature of about 360 ° C. The deodorized mixed gas is discharged from the exhaust port 82 to the second pipe member 72.
Of the second pipe member 72 and discharged to the outside. At this time, the mixed gas is the second pipe member 7
When passing through 2, heat is exchanged with the untreated odorous gas passing through the second route R2, and heat is given to the untreated odorous gas by applying heat.

As described above, the garbage processing system 100 according to the present embodiment deodorizes the gas containing odor during the garbage processing and evaporates the drain water generated in the pipe 3 to deodorize it. Can be discharged. Therefore,
The occurrence of the problem that the pipe 3 is clogged with drain water is reduced. Thus, this garbage processing system 100 is
The odorous gas containing the odorous component and the drain water generated in the pipe 3 can be deodorized and treated. And
The heat used to treat the drain water is originally the heat released to the outside together with the exhaust gas. Therefore, in the garbage processing system 100, the exhaust heat is effectively used, and energy saving is realized.

[Other Embodiments] (a) In the above-described garbage processing system 100, the deodorizing device 2 is provided outside the garbage processing device 1 and is separate from the garbage processing device 1. The deodorizing device 2 may be incorporated in the garbage processing device. (B) The liquid treated in the deodorizing device 2 is not limited to the drain water generated in the pipe 3, but, for example, by providing a liquid flow path for sending the liquid generated in the garbage processing device 1 to the gas path R3. The liquid generated in the raw garbage processing device 1 can also be processed.

(C) In the above-described embodiment, the deodorizing device 2
Is combined with the raw garbage processing apparatus 1, but is not limited to the raw garbage processing apparatus 1, and may be combined with an apparatus for processing commercial waste or household waste other than raw garbage. Even when odorous gas and liquid are generated when such dust is treated, the odorous gas and liquid can be treated as in the above-described embodiment.

(D) By connecting the other end of the drain pipe 6 to the inside of the second pipe member 72, it is possible to guide the drain water to the high-temperature treated gas after passing through the catalyst heating chamber 81. is there. In this case, the drain water is vaporized and discharged without lowering the temperature of the pretreatment gas.

[0037]

In the deodorizing apparatus according to the first aspect of the present invention, since the liquid charging unit charges the liquid to the gas whose temperature has passed through the heat exchange unit, the charged liquid evaporates by receiving heat from the gas. . In this way, the liquid evaporates and becomes a gas, and is discharged as a gas together with the gas that has passed through the heat exchange section. On the other hand, the gas containing the odor component is deodorized and discharged to the outside.

In the deodorizing apparatus according to the second aspect, since the liquid is added to the unprocessed gas before passing through the processing unit, the liquid is vaporized into gas and then passes through the processing unit and is deodorized by the processing means. It For this reason, even when the liquid contains an odor component and the odor component remains after vaporization, the odor component is deodorized, and the possibility of the bad odor of the discharged gas becoming a problem becomes smaller.

Since the waste treatment system according to claim 3 comprises the waste treatment device and the deodorizing device, the waste treatment device treats the waste and at the same time, the odorous gas and liquid generated during the treatment of the waste. Can be processed.
In particular, even when a liquid is generated when treating the waste, the liquid can be evaporated and discharged from the deodorizing device to the outside together with the gas after the deodorizing treatment.

In the waste treatment system according to claim 4,
The liquid generated in the pipe is put into the pretreatment gas before passing through the treatment section by the deodorizing device. Then, the liquid evaporates and becomes a gas and is discharged. Therefore, it is prevented that the liquid is generated in the pipe and the processing of the waste in the waste processing apparatus is hindered. In the waste treatment system according to claim 5, since the pipe is high on the waste treatment device side and low on the deodorizing device side and continuously inclined, the liquid generated in the pipe is directed to the deodorizing device side by gravity. It flows and is processed by the deodorizing device. Therefore, it is possible to prevent the liquid generated in the pipe from flowing to the waste treatment device side and hindering the discharge of gas from the waste treatment device.

In the waste treatment system according to claim 6,
The liquid generated in the pipe is stored in the drain trap and then processed by the deodorizing device. Therefore, it is possible to prevent the liquid generated in the pipe from flowing back to the waste treatment device side.
