Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorizing apparatus for removing various malodorous substances, and more particularly, to a process in which a processing gas and a regeneration gas are passed through a rotor while a honeycomb-shaped rotor is rotationally driven, thereby causing malodor. The present invention relates to a deodorizing device for decomposing and removing components.

[0002]

2. Description of the Related Art Heretofore, malodorous substances have been removed by an adsorption rotor composed of only an adsorbent such as zeolite or activated carbon. In this conventional deodorizing apparatus, when the object to be removed is a gas containing an aromatic hydrocarbon such as phenol, a part of the gas component adsorbed on the rotor is thermally polymerized in the regeneration step, and the inside of the micropower of the rotor is removed. And the adsorbability of the rotor is reduced.

[0003] In order to solve this drawback and extend the life of the adsorbent, there is a deodorizing apparatus in which a filter that can be easily replaced is installed upstream of the adsorption rotor in the flow direction of the processing gas. However, this conventional apparatus has a drawback that the cost of replacing the filter causes an increase in running cost.

Further, in a conventional deodorizing apparatus using an adsorption rotor, in order to regenerate an adsorbent, heated air is passed through the rotor, and the rotor is heated to deodorize odor components adsorbed on the rotor. . However, the gas after the regeneration of the rotor, that is, the gas containing the high-concentration odor component after the deodorization component has been desorbed from the rotor, must be treated by another device, which has led to an increase in the size of the device.

On the other hand, in a deodorizing apparatus in which a rotor is constituted only by a catalyst and a gas containing a malodorous component is decomposed and removed by the catalyst, the malodorous substance on the catalyst is decomposed in the regeneration step, so that the life of the rotor is not extended. Although it is possible, since the specific surface area of the catalyst is small, there is a drawback that the adsorption capacity for malodorous substances is small, and substances having strong odor cannot be sufficiently deodorized.

Accordingly, the present inventors have already proposed a deodorizing apparatus using a mixture of a catalyst and an adsorbent for a rotor (Japanese Patent Laid-Open No. 7-256048). FIG. 4 shows this conventional deodorizing device. The deodorizing rotor 1 has a cylindrical shape, and is rotatably supported around its central axis. The rotor 1 is driven to rotate in one direction by appropriate driving means. In addition, the front and rear surfaces of the rotor 1 face rooms divided into three by partitions, and in these three zones, a predetermined gas can be passed in the thickness direction of the rotor 1 without mixing with other zones. I can do it. As shown in FIG. 3, this zone includes an adsorption treatment zone 1a, a purge zone 1b, and a regeneration zone 1c.
Degrees and 45 degrees.

The deodorizing rotor 1 has a structure in which a hydrophobic zeolite as an adsorbent and an oxidation catalyst as a catalyst are mixed, and this mixture is supported on a honeycomb ceramic substrate.

After the dust to be deodorized is removed by the filter 2, the air is introduced into the processing zone 1 a of the rotor 1 through the pipe 6. This processing air is sent into the rotor 1 by the blower 3 provided in the pipe 6. The air that has exited the processing zone 1a is discharged to the outside via the pipe 7.

A part of the odorless air after the deodorization treatment discharged into the pipe 7 is introduced into the purge zone 1b of the rotor 1 through the pipe 8.

On the other hand, the regeneration air is circulated to the regeneration zone 1c of the rotor 1 by a pipe 9, and is driven by a blower 4 provided in the pipe 9 so that the regeneration air is supplied to the regeneration zone of the rotor 1. 1c is circulated. On the upstream side of the regeneration zone 1c of the pipe 9, a regeneration air heater 5 is disposed. The regeneration air is heated to about 350 ° C. by the heater 5 and then introduced into the regeneration zone 1c of the rotor 1. You. Thus, the air after passing through the purge zone 1b is supplied to the recycled air circulation pipe 9 via the pipe 9a. Further, a pipe 10 is connected to a position on the downstream side of the blower 4 in the pipe 9, and a part of the regenerated air is extracted through the pipe 10 and mixed with the processing air before passing through the rotor. I have.

Next, the operation of the conventional deodorizing apparatus configured as described above will be described. The processing air containing the offensive odor gas is sent to the processing zone 1a of the deodorizing rotor 1, and the offensive odor component is adsorbed and removed by an adsorbent portion made of a hydrophobic zeolite constituting a part of the rotor 1. The air after passing through the processing zone is discharged as purified air.

Then, the rotor 1 having absorbed the malodorous component rotates to the regeneration zone 1c. Then, in the regeneration zone 1c, the malodorous component adsorbed on the rotor 1 becomes
By heating the rotor 1 with high-temperature air heated by the regeneration heater 5, the rotor 1 is detached from the adsorbent portion of the rotor 1. Regenerated air containing a high concentration of malodorous components desorbed from the rotor 1 circulates through the regeneration path via the pipe 9 and is introduced into the heater 5. Then, the regeneration air containing the malodorous component at a high concentration passes through the rotor 1 at a high temperature in the regeneration zone 1c, and the catalytic portion of the rotor 1 oxidizes and decomposes the malodorous component.

Next, the rotor 1 heated to a high temperature in the regeneration zone 1c rotates to the purge zone 1b. The rotor 1 is cooled by the passage of the clean air after the adsorption process in the purge zone 1b. As a result, the ability of the rotor 1 to adsorb bad odor components is restored, and the rotor 1 is subjected to the next adsorption process in the processing zone 1a.

In this apparatus, the heat after the purging is recovered from the air after the purging, in which the heat of the rotor is transferred, without discharging the purged air to the outside air as it is or returning it to the processing inlet air. The air after the purge is introduced into the pipe 9 of the circulation regeneration air path. Then, air of substantially the same amount as the purged air introduced into the pipe 9 is extracted from the pipe 9,
This is returned to the upstream side of the processing blower 3 via the pipe 10 and mixed with the air before the processing. The air extracted from the pipe 9 is returned to the pipe 6 because the extracted air contains a trace amount of undecomposed malodorous gas.

As described above, according to this embodiment, a gas containing a malodorous component can be deodorized with high efficiency.
That is, even when a gas containing an aromatic hydrocarbon such as toluene, xylene, and phenol is deodorized, the adsorbed substance is decomposed by the catalyst in the regeneration zone 1c, and the adsorbed substance remains on the rotor due to thermal polymerization. And the life of the rotor is not shortened. In addition, regardless of the form in which the catalyst is added to the adsorbent, the catalyst is constituted by a honeycomb-shaped rotor, so that its specific surface area is large and a substance having a strong odor can be sufficiently deodorized. Furthermore,
Since the deodorizing treatment is performed only by the rotor 1, the apparatus does not become large and the running cost is low.

[0016]

However, since this conventional deodorizing apparatus uses clean air after processing as a purge gas, the cooling efficiency of the rotor is low, and
There is a disadvantage that the processing capacity is small.

That is, the treated clean gas in the pipe 7 cools the rotor in the purge zone 1b, but the purge gas passes through the treatment zone 1a and has a relatively high temperature. Is low. Further, in the conventional apparatus, the rotor is divided into three, a processing zone 1a, a regeneration zone 1c, and a cooling zone (purge zone 1b) by a partition plate on a processing air inlet side. For this reason, the processing air volume decreases.

The present invention has been made in view of such a problem, and by improving the processing flow, even when deodorizing a gas containing an aromatic hydrocarbon such as phenol, the thermal polymerization of the adsorbed substance can be carried out. The performance of the rotor is not reduced, the running cost is low, the processing of gas after rotor regeneration is unnecessary, the odor can be strongly removed, and the cooling efficiency of the rotor is high, An object of the present invention is to provide a deodorizing device capable of increasing the capacity.

[0019]

According to the present invention, there is provided a deodorizing apparatus comprising: a honeycomb-shaped rotor; driving means for driving the rotor to rotate about its central axis; Dividing means for dividing the processing air into first and second regeneration zones and a purge zone in this order; processing air introducing means for passing processing air through the rotor in the processing zone; and a part of the processing air in the purge zone. Means for passing purge gas as a purge gas, heating air circulating means for circulating the heating air for regeneration to the second regeneration zone, and supplying a part of the heating air for regeneration to the first regeneration zone. Heating air supply means for regeneration, return means for returning the regenerated gas from the first regeneration zone to the inlet side of the processing zone, and purging after passing through the purge zone And a means for introducing a gas into the circulation path of the regeneration heating air.

The first invention of the present application is characterized in that, in the deodorizing apparatus, the honeycomb-shaped rotor is formed by molding a mixture of a catalyst and an adsorbent or a honeycomb substrate with the mixture.

Further, the second invention of the present application is the deodorizing apparatus, wherein the honeycomb-shaped rotor is formed by superposing a portion constituted by a catalyst and a portion constituted by an adsorbent in a gas flowing direction. Features.

In the present invention, the rotor that has absorbed the malodorous component in the processing air in the processing zone is heated by receiving the flow of the regeneration-use heating air in the first and second regeneration zones to desorb the malodorous component. . Then, the rotor receives the flow of the purge gas in the purge zone in order to increase the adsorption efficiency, receives the cooling and purges the residual malodorous components, and then rotates to the processing zone. Therefore, a high-temperature gas heated by a heater or the like is used as the regeneration gas, and the post-regeneration gas contains a high concentration of malodorous components.

In the present invention, since a residual gas component in the rotor is purged and a part of the processing air to be deodorized from now on is used as the purge gas for cooling the rotor instead of the air after the deodorization processing. The cooling efficiency is improved, the adsorption efficiency is increased, and the processing capacity is increased. In addition, since a part of the processing air flows through the purge zone, the same processing air flows as the processing zone, and a partition between the purge zone and the processing zone is unnecessary.

The regeneration zone is supplied with a heating gas for regeneration in the circulation path. The exit of the regeneration zone is divided into two, and the post-regeneration gas that has passed through the rotor at the initial stage of the regeneration of the rotor is treated. Return to the entrance side of the zone. The rotor exiting the processing zone is relatively cool, and in a first regeneration zone adjacent to the processing zone, the heat of the hot regeneration air is mostly used to heat the rotor. Therefore, the temperature of the post-regeneration gas exiting the first regeneration zone is relatively low. Therefore, even if the post-regeneration gas exiting the first regeneration zone is returned to the inlet of the processing zone, the temperature of the processing air is not increased and the adsorption efficiency of the rotor is not reduced. Since the post-regeneration gas contains a large amount of malodorous components, it is subjected to adsorption treatment again in the treatment zone.

In the present invention, the rotor is formed by molding a mixture of a catalyst and an adsorbent, or by impregnating the mixture with a honeycomb substrate, or by passing a catalyst portion and an adsorbent portion in a gas flow direction. Therefore, the rotor of the present invention exhibits the effects of both the adsorbent and the catalyst.

Therefore, when an aromatic gas represented by phenol is passed through the rotor in the treatment zone, the malodorous components in the gas are adsorbed by the adsorbent portion of the rotor and decomposed by the catalyst portion. You. Thus, by adsorbing and decomposing the aromatic gas, the life of the deodorizing rotor can be extended as compared with the case of using only the adsorbent.

In addition, even for a gas having a strong odor, the adsorbent portion can remove malodorous substances with high efficiency by taking advantage of its adsorption capacity, and furthermore, can be decomposed by a catalyst to deodorize in one apparatus. Since the substance can be processed, the size of the device can be reduced.

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a block diagram showing a deodorizing device according to an embodiment of the present invention, FIG. 2 is a diagram showing a structure around the rotor, and FIG. 1 and 2, components having the same functions as those in FIG. 3 are denoted by the same reference numerals, and detailed description thereof will be omitted. The deodorizing rotor 1 has a cylindrical shape, is rotatably supported around its central axis, and is driven to rotate in one direction by a suitable driving means. And the rotor 1 is in the processing zone 1
a, a first regeneration zone 1d, a second regeneration zone 1e, and a purge zone 1b. As shown in FIG. 2, a first regeneration zone 1
A regeneration zone entrance chamber 20 is provided at a position facing both the first regeneration zone d and the second regeneration zone 1e, and a purge zone exit chamber 21 is located at a position facing the purge zone 1b.
Are arranged. Also, on the other surface side of the rotor 1,
An outlet chamber 22 of the first regeneration zone 1d and an exit chamber 23 of the second regeneration zone 1e are provided. Each chamber allows a predetermined gas to pass in the thickness direction of the rotor 1 without mixing with other zones.

At least one component selected from the group consisting of zinc and nickel. The rotor 1 of the present embodiment is, for example, C
It is an oxidation catalyst containing uO: 15 to 30% and MnO: 40 to 60% as main components. Further, the adsorbent is not limited to hydrophobic zeolite, and various substances such as activated carbon can be used. Also, the catalyst is not limited to an oxidation catalyst,
Noble metal catalysts such as platinum and palladium can also be used.

The rotor 1 may be one in which the mixture is directly formed into a honeycomb rotor shape without supporting the mixture on a ceramic base material. Further, as shown in FIG. 3, the rotor 1 is also used in which two rotors of an adsorbent portion 32 of hydrophobic zeolite and an oxidation catalyst portion 31 are overlapped. In this case, the catalyst part 3
The rotor can be arranged such that 1 is on the upstream side of the flow direction of the gas to be treated (downstream of the regeneration gas) and the adsorbent portion 32 is on the downstream side of the gas to be treated (upstream of the regeneration gas). . This is because, in the regeneration zones 1d and 1e, first, a thermopolymerizable component such as phenol adsorbed on the adsorbent portion 32 is desorbed by a high-temperature regeneration gas, and then the malodorous component is removed from the catalyst portion at the high temperature Into the catalyst part 31
This is for removing the catalyst by decomposition. However, the present invention is not limited to this, and the arrangement of the adsorbent portion 32 and the catalyst portion 31 may be reversed.

After the dust to be deodorized is removed by the filter 2, the air is introduced into the processing zone 1 a of the rotor 1 through the pipe 6. This processing air is sent into the rotor 1 by the blower 3 provided in the pipe 6. The air that has exited the processing zone 1a is discharged to the outside via the pipe 7.

A part of the processing air flowing through the pipe 6
It is introduced into the purge zone 1 b of the rotor 1 by a pipe 11 branched from the pipe 6. The purged gas that has passed through the purge zone 1b once enters a purge outlet chamber 21 arranged on one surface side of the rotor 1, and then, via a pipe 12, upstream of a blower 4 of a pipe 13 described later. Will be returned. As is clear from FIG. 2, the branch pipe 11 is provided for convenience of explanation in FIG. 1, and in actuality, the pipe 6 is connected to a portion other than the chambers 22 and 23 of the rotor 1 to process air. The chambers 22, 2 of the rotor 1
It is sufficient to supply to parts other than 3. That is, it is only necessary to connect the pipe 6 as it is to a portion other than the chambers 22 and 23 of the rotor 1 without specially providing the pipe 11 branched from the pipe 6.

On the other hand, in the second regeneration zone 1e of the rotor 1, heated air for regeneration is circulated by a pipe 13 and a branch pipe 13b thereof, and is driven by a blower 4 provided in the pipe 13. The heating air for regeneration is circulated and supplied to the second regeneration zone 1e of the rotor 1. In addition, the heating air for regeneration flowing through the pipe 13 is introduced into the first regeneration zone 1d by the pipe 13a branched from the pipe 13. Further, the post-regeneration gas that has passed through the first regeneration zone 1d is returned to the pipe 6 upstream of the blower 3 via the pipe 14. As shown in FIG.
a and 13b are both the regeneration inlet chamber 20 of the rotor 1.
The regeneration heating air is supplied into the regeneration inlet chamber 20. Heated air for regeneration is supplied from the chamber 20 to the first and second regeneration zones 1d and 1e of the rotor 1.
Supplied to As is clear from the above description, the branch pipes 13a and 13b are provided for convenience of description in FIG. 1, and as is clear from FIG. It suffices to supply the gas to the chamber 20, and it is not necessary to branch into two pipes. On the other hand, the outlet chamber 22 of the first regeneration zone and the outlet chamber 23 of the second regeneration zone are disposed on the outlet side of the post-regeneration gas of the rotor 1 as described above.
The pipe 13 is connected to the outlet chamber 23 of e.
The pipe 14 is connected to the outlet chamber 22 of the first regeneration zone 1d. The pipe 14 is connected to the pipe 6 so that the post-regeneration air after passing through the first regeneration zone is returned to the pipe 6.

On the upstream side of the regeneration zone 1d of the pipe 13,
A regeneration air heater 5 is provided. The regeneration air is heated to about 350 ° C. by the heater 5 and then introduced into the regeneration zones 1 d and 1 e of the rotor 1.

Next, the operation of the deodorizing device configured as described above will be described. The treated air containing odorous gas is
The odor component is sent to the processing zone 1a of the deodorizing rotor 1, and the malodorous component is adsorbed and removed by an adsorbent portion made of a hydrophobic zeolite constituting a part of the rotor 1. The air after passing through the processing zone is discharged as purified air.

Then, the rotor 1 adsorbing the offensive odor component rotates into the first regeneration zone 1d and the second regeneration zone 1e. Then, in the first regeneration zone 1d and the second regeneration zone 1e, the rotor 1 is heated by the high-temperature air heated by the regeneration heater 5, and the malodorous component adsorbed on the rotor 1 is removed by the adsorbent of the rotor 1. Detachable from part. The regenerated air containing a high concentration of malodorous components desorbed from the rotor 1 is then oxidatively decomposed by the catalyst portion of the rotor 1. In this manner, the air after the odorous components are oxidized and decomposed is supplied to the outlet chamber 22 of the first regeneration zone 1d and the outlet chamber 23 of the second regeneration zone 1e.
And the regenerated air in the outlet chamber 22
Is returned to the pipe 6 on the inlet side of the processing zone. On the other hand, the regenerated air in the outlet chamber 23 is discharged to the pipe 13 and circulated to the rotor 1 via the pipe 13.

The rotor 1 has a relatively low temperature immediately after passing through the processing zone 1a. Therefore, the post-regeneration air passing through the first regeneration zone 1d is deprived of heat by the rotor 1 and has a relatively low temperature. Therefore, even if the post-regeneration air after passing through the first regeneration zone 1d is returned to the pipe 6, the adsorption efficiency in the processing zone is not reduced. On the other hand, the post-regeneration air after passing through the second regeneration zone 1e has a relatively high temperature since the rotor 1 has passed through the first regeneration zone 1d, so that the degree of cooling by passing through the rotor is low. is there. Therefore, the post-regeneration air after passing through the second regeneration zone 1e is supplied to the circulation path through the pipe 13, so that the amount of heat required for heating the regeneration gas by the heater 5 is reduced.

Next, the rotor 1 heated to a high temperature in the regeneration zones 1d and 1e rotates into the purge zone 1b. Then, the rotor 1 is cooled by receiving the passage of the processing air introduced from the pipe 11 in the purge zone 1b. As a result, the ability of the rotor 1 to adsorb bad odor components is restored, and the rotor 1 is subjected to the next adsorption process in the processing zone 1a.

In this embodiment, the heat after the purging is transferred from the purged air to which the heat of the rotor is transferred without being discharged to the outside air as it is or returned to the processing inlet air. In order to collect the air, the air after the purge is introduced into the pipe 13 of the circulation regeneration air path. And piping 1
A substantially equal amount of air after the purged air introduced into 3 is extracted from the pipe 13, returned to the upstream side of the processing blower 3 via the pipe 14, and mixed with the air before the processing. In addition,
Returning the air extracted from the pipe 13 to the pipe 6
This is because the extracted air contains a small amount of undecomposed malodorous gas.

As described above, according to this embodiment, the gas containing the malodorous component can be deodorized with high efficiency.
That is, even when deodorizing a gas containing aromatic hydrocarbons such as toluene, xylene and phenol, the adsorbed substances are decomposed by the catalyst in the regeneration zones 1d and 1e.
It does not remain on the rotor due to thermal polymerization and does not shorten the life of the rotor. In addition, regardless of the form in which the catalyst is added to the adsorbent, the catalyst is constituted by a honeycomb-shaped rotor, so that its specific surface area is large and a substance having a strong odor can be sufficiently deodorized. Further, since the deodorizing process is performed only by the rotor 1, the apparatus does not become large and the running cost is low.

Further, in the present invention, since the processing air is used as the purge gas, a chamber for separating the processing air and the purge gas on the inlet side of the rotor 1 is not required, and the conventional deodorizing apparatus shown in FIG. Therefore, the device is simplified. Furthermore, since a chamber for separating the processing air and the purge gas is not required, the processing capacity is increased.

When the rotor made of the material of the present invention is used, the regeneration temperature is considered to be high, and there is a possibility that the adsorption effect may be reduced due to insufficient cooling of the rotor. However, according to the processing flow of the present invention, Since the processing air in the pipe 6 is supplied to the purge zone 1b and cooled, the flow rate of the cooling air passing through the purge zone 1b can be increased without increasing the flow rate in the circulation path, and the rotor 1 can be sufficiently cooled. To maintain the adsorption effect at a high level.

[0043]

As described above, according to the present invention,
Since the processing air before the adsorption processing is used as the purge gas, a partition member between the processing zone and the purge zone at the rotor inlet becomes unnecessary, and the apparatus is simplified.

In addition, although the post-regeneration air is returned to the processing air piping, in the present invention, the regeneration zone is divided into a first regeneration zone and a second regeneration zone, and relatively low-temperature post-regeneration air flows out. Since the post-regeneration air from the first regeneration zone coming back is returned to the processing air piping, the temperature of the processing air supplied to the processing zone is not increased and the adsorption efficiency of the rotor is not degraded.

Further, in the present invention, since the rotor is constituted by mixing the adsorbent and the catalyst or by overlapping the adsorbent portion and the catalyst portion, the thermopolymerizable gas containing aromatic hydrocarbons is deodorized. In this case, the rotor performance is not reduced, the life is long, and the odor component can be removed and deodorized with high efficiency and low running cost.
