Description

  The present invention relates to an activated carbon gas treatment apparatus that can be used for deodorization from outside air by bringing outside air into contact with an activated carbon group, and further, for removing harmful substances and volatile gas as necessary.

  Patent Document 1 includes a carrier packed tower whose inside is a sealed air passage, and a plurality of carrier storage boxes (cartridges) in which microbial groups are stored are provided inside the tower, and the carrier storage box Are supported by a guide track formed between the inner surface of the carrier packed tower and can be pulled out laterally of the carrier packed tower through the opening and closing port of the carrier packed tower. A microbial deodorizing apparatus is disclosed.

  In this microbial deodorization apparatus, the carrier storage box is of a horizontal drawer type, so that the labor for replacing microorganisms is reduced, but the carrier storage box has a structure for directly storing a bare microbial group. Therefore, when exchanging microorganisms, it is inevitable that workers and the surrounding environment are polluted and it takes a lot of time to take out and put in a bare microorganism group. In addition, since the plurality of carrier storage boxes are arranged in series in the air passage, the outside air sequentially passes through each of the microorganism groups stored in the plurality of carrier storage boxes, and the pressure loss when passing the microorganism groups is reduced. Therefore, it is necessary to increase the discharge pressure of the blower fan for flowing outside air, and as a result, the power consumption and noise of the blower fan are increased, and the installation space in plan view is also increased. is there.

  Further, Patent Document 2 discloses activated carbon in which activated carbon is stored in a plurality of stages and fixed with screws, and external air passes through each of these cartridges simultaneously in parallel. An adsorption tower is disclosed.

  In this activated carbon adsorption tower, the capacity of deodorizing treatment can be conveniently changed by arbitrarily changing the number of cartridge stages. However, when replacing the activated carbon in each cartridge, the screwing between the cartridges is released and the cartridge to be replaced is replaced. It takes a lot of trouble to move the to the floor.

  Further, Patent Document 3 discloses an adsorbent in which adsorbent groups are arranged in two upper and lower stages in a filter frame, and gas flows in parallel and vertically symmetrically with respect to these adsorbent groups. A deodorizing device is disclosed in FIG. However, this document does not mention exchange of adsorbent groups.

Further, in the conventional gas treatment apparatus that performs deodorization using activated carbon as described above, for example, when the amount of the activated carbon is relatively large such that it exceeds approximately several m ³ , Special knowledge is required due to the necessity of using a vacuum machine, etc., so it is difficult or impossible to implement by inexperienced people, and it can be said about almost everything that contains bare activated carbon in the cartridge However, there is a problem that fine powder of the activated carbon group in the cartridge flows out of the apparatus when starting the apparatus immediately after replacement of the activated carbon.

  On the other hand, nowadays, with the improvement of living standards, there are many problems of bad odor pollution in densely populated areas such as urban areas and dining spaces, stores, etc., and this situation can be reasonably addressed. The advent of gas treatment equipment is desired.

Japanese Patent Laid-Open No. 9-19622 JP 2001-129345 A Japanese Utility Model Publication No. 5-49023

  The present invention was devised in view of the above-mentioned problems and demands, that is, it does not take much time to contaminate workers and the surrounding environment when replacing activated carbon, It is another object of the present invention to provide an activated carbon gas treatment apparatus that reduces power consumption and noise of the blower fan and reduces the installation space in plan view.

In order to achieve the above object, the activated carbon gas treatment apparatus according to the present invention is a box having an air circulation port for sucking air and an air circulation port for letting it out and a ventilation space inside as described in claim 1 . A casing having a shape, a blower fixed to the inside of the casing and allowing air in the casing to flow between the two air circulation ports, and an arbitrary number of cartridges in which activated carbon groups are accommodated by the blower And a cartridge through which flowing air flows in / out, and can be pulled out to the front outside of the casing through the opening / closing port of the casing in a state where the cartridge is supported by a guide track formed between the casing and the casing. a charcoal gas processing devices that are So設as such, the cartridge, the upper surface is opened, horizontally long face latter of the side peripheral surface is above the height center Has a through hole, and made to that bottom portion is hooked to the intermediate support plate having a large number of vent holes in a specific height position of the body the housing frame provided with a housing frame body having a large number of vent holes The activated carbon package having a specific thickness in which the activated carbon group is wrapped with a packaging material is loaded on each of the upper surface portion of the bottom surface portion and the upper surface portion of the intermediate support plate, and is pushed backward into the casing. The cartridge in a state where the bottom surface portion and the top surface of the cartridge communicate with one of the air circulation ports, while the activated carbon package and the intermediate support plate loaded at the top surface portion of the bottom surface portion. A space formed between the activated carbon packages loaded in the upper surface portion communicates with the other air circulation port via the horizontally long through hole, and is forcedly guided into the casing by the blower. It was outside air It is characterized in that the flow out the activated carbon package loaded on the upper surface portion of the bottom portion, or to the housing casing passes through one of the intermediate support plate activated carbon package loaded on the upper surface portion of the .

The present invention is preferably embodied as follows.
That is, as described in claim 2, the activated carbon package is wrapped with a packaging material that prevents the fine powder of the activated carbon group from flowing out.

Further, the packaging material functions as a filter for removing dust .

Also as described in claim 3, according to the active carbon package exchange method of the activated carbon gas treatment device, in a state in which the cartridge is pulled out forward outside of the casing is supported on the guide track portion, in the housing frame against the activated charcoal package of the upper, intermediate support plate, and, extracting the respective lower side of the active carbon package upwardly separately, and restoring by inserting individually from above after thus withdrawn .

Further, as defined in claim 4 , the other air circulation port is formed on one surface of the two surfaces of the casing facing each other in the guide direction of the guide track portion, corresponding to each of the cartridges. In addition, in the casing in the vicinity of the other surface, there is provided a press-fixing means for pressing the through hole of the side peripheral surface portion of the housing frame of the cartridge against the other air circulation port in the casing. The opening / closing port is provided on the other surface.

According to the present invention described above, the following effects can be obtained.
That is, according to the first aspect of the present invention, even if the activated gas treatment apparatus has a flow rate of the gas to be treated exceeding, for example, about 5 m 3 / min, the activated carbon group that has been broken through in the apparatus is detected. When exchanging, open the opening / closing port, pull out the side of the box-shaped casing while supporting the cartridge through the guide track through this, and in this state, first take out the upper activated carbon package from the inside of the cartridge, then the intermediate support plate removed from the cartridge upward, then Ru can be processed to retrieve the bottom of the activated carbon package upward.

  In addition, parallel processing is performed in which the outside air guided into the box-shaped casing is individually guided to the upper and lower activated carbon packages, and passes through the corresponding one activated carbon package and flows out of the box-shaped casing. Therefore, when the same processing capability is exhibited, the outside air is processed in a state where the pressure loss is small, and the blower is reduced in size, power saving and noise reduction.

In addition, by increasing or decreasing the number of cartridges, the processing capacity can be changed to an arbitrary size while ensuring the above-mentioned effects, and the type, component, mixing ratio, etc. of the activated carbon group in the activated carbon package are specified by the specialized manufacturer. By changing it, even if an activated carbon replacement operator or the like does not have expertise in activated carbon, the replacement can be easily performed and any kind of gas can be purified.
As described above, it is possible to conveniently and rationally remove various bad odors and their combined odors in densely populated areas such as urban areas, living spaces such as canteens and stores.

According to the second aspect of the present invention, particularly immediately after replacement of the activated carbon group, a phenomenon in which fine dust in the activated carbon group in the activated carbon package is mixed into the purified fluid and flows out into the atmosphere. It can be surely prevented to an arbitrary fixed level or less .

Also, since dust in the gas to be treated is removed by a filter before the gas to be treated enters the activated carbon group in the activated carbon package, clogging of the activated carbon group is prevented and deterioration of the purification function of the activated carbon group is suppressed. In addition, the dust contained in the air that permeates the activated carbon package is removed by the filter.

According to the third aspect of the present invention, a pulling force is applied to the cartridge supported by the casing via the guide track portion, and the cartridge is pulled out to the lateral side of the casing. By pulling out each of the packaging body, the intermediate support plate, and the lower activated carbon packaging body separately, replacing the activated carbon packaging body on each of the upper and lower sides with a new one, and performing the reverse procedure described above, It becomes capable of performing replacement attachment of activated carbon not lift the cartridge. Also, since the upper activated carbon package, the intermediate support plate, and the lower activated carbon package are extracted from the cartridge and the cartridge is emptied, maintenance inside the cartridge can be easily performed. .

According to the fourth aspect of the invention, the through hole in the side peripheral surface portion of the housing frame of each cartridge and the air circulation port 6 that communicates the inside and outside of the casing are pressed regardless of the weight of the cartridge. By press-contacting with a pressing force by fastening means (in addition to screws, an elastic body such as a patchon lock, a spring, or a rubber is considered), the sealed space g1 in the cartridge and the air circulation port 6 are Can be communicated in an airtight manner, so that even if the weight of the cartridge is small, a structure in which the air flowing through the casing surely permeates the activated carbon package on the upper and lower sides of each cartridge is formed. In addition, the pressing and fastening means can be conveniently operated under the condition that the opening / closing port is opened.

The blower 9 includes an electric motor 9a and an impeller 9b that is rotationally driven by the motor 9a. Through the operation of the electric motor 9a, the blower 9 passes through the upper air circulation port 3, the upper space c1, and the through hole d1 of the partition plate 8. The outside air is sucked and sent out downward in the box-shaped casing 1.

  In the vicinity of the lower side of the blower 9, a horizontal baffle plate 10 that is a state in which the inner space of the box-shaped casing 1 is vertically divided except for the front portion thereof is formed integrally with the box-shaped casing 1. Is provided.

  Reference numeral 11 denotes a cartridge disposed in the lower space of the baffle plate 10. As shown in FIG. 5, the cartridge 11 includes a housing frame 12 having a side peripheral surface portion 12a having an open top surface and a flat plate, and a bottom surface portion 12b in which a large number of vent holes e1 are formed.

Then, activated carbon packages 14 and 14 having a specific thickness and having a weight of about 10 kg or less are densely loaded on the upper surface portion of the bottom surface portion 12b of the cartridge 11 and the upper surface portion of the intermediate support plate 13, respectively. ing.

  Between the cartridge 11 and the left and right side surfaces 1e and 1f of the box-shaped casing 1, as shown in FIG. 4, the cartridge 11 is moved to the front outer side of the box-shaped casing 1 with little resistance while being supported horizontally. Specifically, for example, while the slide rails 15a are fixed to the left and right portions of the side peripheral surface portion 12a of the housing frame 12, the left and right sides of the box-shaped casing 1 are fixed, for example. A support guide means 15b for supporting the slide rail 15a so as to be movable back and forth is provided on the inner surface of the slider.

  In the box-shaped casing 1 in the vicinity of the front surface portion 1a, screw pressing and fastening means 16 for pressing the rear surface portion of the side peripheral surface portion 12a of the cartridge 11 against the lower air circulation port 6 (front end surface of the guide tube member 6a). Is provided. The screw pressing and fastening means 16 may be arbitrarily formed, but in the illustrated example, two screw pressing and fastening means 16 and 16 are formed in a symmetrical pair in the vicinity of the front surface portion 1a.

  Each of the screw pressing fixing means 16 includes an operation mechanism portion 17 provided at the left and right end portions of the front surface portion of the side peripheral surface portion 12a of the housing frame 12, and an engagement hole formed at the front portion of the support guide means 15b. It consists of 18. As shown in FIG. 5, the operation mechanism portion 17 is inserted into the bag-shaped guide member 17a fixed to the side peripheral surface portion 12a, and the guide member 17a is displaceable in the left-right direction a2 and displaceable in the front-rear direction a1.

On the other hand, the engaging hole 18 is relatively deeply fitted to the distal end portion of the movable plate 17b that is displaced outward in the left-right direction a2 by applying the operating force in the left-right direction a2 to the push bolt 17c, and thus the movable plate 17b is fitted. It is supposed to be fixedly supported.

  Accordingly, when the cartridge 11 is pushed rearward and the push bolt 17c is screwed in a state where the tip of the movable plate 17b is fitted in the engagement hole 18, the state in which the cartridge 11 is fixedly supported by the engagement hole 18 is obtained. The push bolt 17c pushes and moves the cartridge 11 rearward through the movable plate 17b, whereby the horizontally elongated through hole e3 at the center of the rear surface of the housing frame 12 is located at the front end surface b2 of the cylinder member 6a. It will be in the state pressed through packing 7. In this state, the sealed space g1 in the cartridge 11 formed inside the housing frame 12 and between the upper and lower activated carbon packaging bodies 14 and 14 is airtight with the lower air circulation hole 6 through the through hole e3. Communicated with

Here, the activated carbon package 14 will be described with reference to FIGS. 4 and 5.
The activated carbon package 14 is obtained by wrapping the outer surface of the activated carbon group in which the small activated carbons 14a are aggregated with a packaging material 14b such as a cloth material having appropriate air permeability so that the activated carbon 14a does not leak. A bag body is formed as the packaging material 14b, and the activated carbon 14a is accommodated therein, and finally, the accommodation opening is sealed.

  At this time, the total weight of the activated carbon package 14 is preferably about 8 kg in consideration of carrying. The activated carbon 14a group is adapted to the odor of the object to be treated, and may be only general charcoal, or mixed with basic charcoal or acid gas at an appropriate ratio. There is no problem. The packaging material (bag body) 14b is preferably formed by a thin layer of a flexible filter. In this way, the activated carbon group performs a gas removal process, and the packaging material 14b performs a dust removal process. To be executed.

  The activated carbon package 14 in this embodiment has a square shape in plan view for easy lifting and movement, the dimensions are 500 to 650 mm in length and about 400 to 500 mm in width, and the thickness is further activated carbon 14a. It is determined in connection with the planned value of the replacement frequency.

  By the way, as shown in FIG. 6A, in the conventional large-sized filling type deodorizing apparatus, in general, a large amount of activated carbon 14a is filled in order to reduce the replacement frequency of the activated carbon 14a. In this conventional apparatus, when the state of property change in the use process of the filled activated carbon 14a is seen, when the use time elapses after the activated carbon 14a is replaced, the adsorption capacity is already consumed as shown in FIGS. 6A and 6B. The three layers of the layer f1 in the post-adsorption state, the adsorption band f2 that is the layer that exhibits the adsorption capability, and the layer f3 in the pre-adsorption state that is not yet exhibiting the adsorption capability As a result, the layer f1 in the post-adsorption state gradually increases as the usage time elapses, and finally the layer f3 in the pre-adsorption state disappears as shown in FIG. 6C. . It should be noted that the layer thickness dimension of the adsorption band layer f2 hardly changes at any time in such a changing process. The layer thickness dimension of the adsorption band f2 is determined by the amount of gas to be processed and the amount of adsorbed components contained therein.

  In the activated carbon package 14 in the embodiment of the present invention, the planned value of the replacement frequency of the activated carbon 14a is about four times a year, and the layer thickness of the activated carbon 14a group is all in the adsorption state f2 when not in use. The size is about several percent to several tens of percent larger than the functioning state. Therefore, the total thickness of the activated carbon package 14 is obtained by adding the total thickness of the cloth (bag) 14b in which the activated carbon 14a group is wrapped to the layer thickness of the activated carbon 14a group.

Next, the usage example of the above-mentioned activated carbon gas processing apparatus and the operation of each part will be described.
For example, the apparatus is installed on a floor in a space where a countermeasure against bad odor is required at a small-scale establishment such as a restaurant service industry.

  As shown in FIG. 3, after the door body 5b is closed to make each part usable, when the blower 9 is started, the outside air first passes through the prefilter 4 due to the suction action of the blower 9, and the inside of the upper space c1. Sucked into. At this time, the pre-filter 4 removes coarse dust in the outside air.

  The blower 9 sends out the sucked outside air below the partition plate 8. The sent outside air is made uniform in flow through the baffle plate 10, guided to the lower front part in the casing 1, and then flows toward the space on the upper and lower sides of the cartridge 11. Then, the fluid flowing into the upper space permeates through the activated carbon 14a group of the upper activated carbon package 14 and flows into the sealed space g1 in the cartridge 11, while the fluid flowing into the lower space is the lower side. The activated carbon package 14 of the activated carbon package 14 passes through the activated carbon 14a group and flows into the sealed space g1 in the cartridge 11 in the same manner.

  At this time, almost all layers of the activated carbon 14a group (general charcoal, impregnated charcoal) in each activated carbon packaging body 14 function as an adsorption zone f2, and the odor and harmfulness in the outside air due to adsorption and chemical reaction due to intermolecular force Remove gas components such as substances.

  Moreover, when the packaging material 14b of the activated carbon packaging body 14 is designed to function as a filter, the packaging material 14b prevents the activated carbon 14a fine powder in the activated carbon 14a group encased therein from flowing out. Stop. Such an action of the packaging material 14b is particularly effective in preventing the outflow of fine activated carbon 14a from the inside of the activated carbon packaging 14 immediately after the activated carbon packaging 14 is replaced with a new one. .

  The purified outside air that has reached the sealed space g1 in the cartridge 11 is pushed by the outside air that reaches after this, and flows out to the atmosphere through the through hole e3 and the lower air circulation port 6.

  For example, when such an operation is performed for about 8 hours every day, the activated carbon 14a group of the activated carbon package 14 is in a breakthrough state after a lapse of usage time of about 3 to 4 months. Replace as follows.

  First, the door 5b is opened as shown in FIG. Next, the push bolts 17c of the pair of left and right operation mechanism portions 17 and 17 are turned to be loosened and then moved by sliding the push bolts 17c toward the center of the left and right width of the cartridge 11 within the range of the long hole d2. The plate 17b is detached from the engagement hole 18. Next, the cartridge 11 is moved outward on the front side of the casing 1 by pulling the handle 12c. At this time, since the guide member 15 supports the weight of the cartridge 11, the cartridge 11 smoothly moves forward with only a small pulling force. Under this state, the upper activated carbon package 14 is first taken out and then taken upward, and then the intermediate support plate 13 is taken up and taken up so that the lower activated carbon package 14 can be seen from above. Later, holding the lower activated carbon package 14 and taking it out upward. Next, in place of the used activated carbon package 14 that has been taken out, a new one is prepared, and the cartridge 11 is restored to the state shown in FIG. Tighten 5b to make it ready for use.

  The replacement operation of the activated carbon package 14 performed as described above is that the shape and weight of the activated carbon package 14 are suitable for manual operation, the intermediate support plate 13 is lightweight, and these members Can be removed by manual operation with a relatively small force without using a tool and restored to the original state.

  Next, in the present invention, an arrangement is adopted in which the upper activated carbon package 14 and the lower activated carbon package 14 are provided, and the outside air is guided to each of the activated carbon packages 14 and 14 and transmitted only once. Mention the utility of.

  In such a configuration, the two activated carbon packaging bodies 14 and 14 are densely stacked to form an integrated body, and when the outside air passes through the activated carbon packaging body 14 as compared with a case where the outside air is permeated once therethrough, The pressure loss can be greatly reduced, which contributes to energy saving and promotion of noise reduction. In order to confirm the degree of this contribution, the inventors set and compared two virtual devices.

As shown in FIG. 7A, one virtual apparatus (corresponding to a conventional apparatus) includes an activated carbon group 14A corresponding to a unitary structure in which the two activated carbon packages 14 and 14 are densely stacked. The other conditions are as follows. That is, the activated carbon group 14A has a length of 650 mm, a width of 400 mm, and a layer thickness of 120 mm, and passes through the activated carbon group 14A. The air volume is 5 m ³ / min, and the layer pressure loss of the activated carbon group 14A is 850 Pa / mBED. The pressure loss of the apparatus under this condition is 102 Pa.

Another virtual device (corresponding to the device of the present invention) includes an upper activated carbon package 14 and a lower activated carbon package 14 as shown in FIG. , 14 are guided separately and transmitted only once, and the other detailed conditions are as follows. That is, each activated carbon group 14B has a length of 650 mm, a width of 400 mm, and a layer thickness of 60 mm. The air volume permeating through the activated carbon group 14B is 5 m ³ / min, and the layer pressure loss of the activated carbon group 14B is 250 Pa / mBED. The pressure loss of the apparatus under this condition is 15 Pa.

  As is clear from the comparison of these two virtual devices, the thickness of the activated carbon group 14A of the former device shown in FIG. 7A is halved and divided into two, and the two activated carbon groups 14B and 14B thus divided into two are divided. In the latter apparatus shown in FIG. 7B arranged in two stages, the pressure loss of the latter apparatus is about 1/7 that of the former apparatus if the air volume (the flow rate of the fluid to be treated) is the same. This is because the pressure loss is reduced by 70% by reducing the passage speed of the fluid in the activated carbon group 14B by 50%, and the pressure loss is reduced by 50% by reducing the layer thickness of the activated carbon group 14B by half. .

As a result of the reduction in pressure loss, when the blower 9 in the former device has an air volume of 5 m ³ / min, a discharge side static pressure of 200 Pa, a rotational speed of 3000 rpm, a power of 100 w, and a noise of 50.5 dB, the latter device is the same as the former device. The air blower 9 used for setting the processing capacity to the extent is sufficient, for example, having an air volume of 5 m ³ / min, a discharge-side static pressure of 100 Pa, a rotation speed of 2400 rpm, a power of 50 w, and a noise of 45 dB.
Therefore, by using the latter device corresponding to the device of the present invention, the power consumption is reduced by half and the noise is reduced by about 6 dB.

Next, a modification of the above-described embodiment apparatus according to the present invention will be described.
