Description

[Detailed description of the invention] This invention relates to a deodorizing device using an adsorbent.

FIG. 1 is a diagram showing an example of the configuration of a conventional adsorption type deodorizing device. In this figure, reference numeral 1 is a deodorizing chamber, and a wire mesh is provided in the vertical center of this deodorizing chamber parallel to the floor surface, and the adsorbent 2 is placed on this wire mesh at a predetermined thickness. has been done. The malodorous gas introduced below the adsorbent 2 from the gas inlet 3 provided on the lower side of the deodorizing chamber 1 is deodorized by passing through the adsorbent 2, and this deodorized gas is transferred to the deodorizing chamber 1. The gas is discharged to the outside from a gas exhaust port 4 provided on the upper side surface of the gas.

The work of refilling the adsorbent in this deodorizing device is carried out as follows. First, an empty bag is set below the adsorbent outlet 5. Next, the used adsorbent 2 is scraped into the bag through the outlet 5. next,
A worker enters the deodorizing chamber 1 and scrapes out what cannot be scraped out from the take-out port 5. Next, workers clean the wire mesh. Next, the bag containing the new adsorbent is lifted onto the deodorizing chamber 1. Next, the lid 6 provided on the top plate of the deodorizing chamber 1 is removed, and the adsorbent is introduced into the deodorizing chamber 1. Next, a worker enters the deodorizing chamber 1 and smooths out the adsorbent.

By the way, the conventional deodorizing device described above has the following problems.

Refilling the adsorbent is difficult and time consuming.

It is necessary to work in the deodorizing chamber 1 filled with adsorbent dust, which is not favorable for the health of the workers.

The generation of adsorbent dust will stain surrounding equipment, walls, etc.

Space for maintenance is required above the deodorizing room.

Next, a deodorizing apparatus shown in FIG. 2 can be considered as a solution to the drawbacks of the conventional deodorizing apparatus. This deodorizing device has a cartridge-type adsorbent mounting section, and when replacing the adsorbent, first open the door 9 provided on the side of the deodorizing chamber 8, enter the maintenance space 10, and enter the square adsorbent container 1.
1, 11, . . . are sequentially carried outside the room using a chain block 12. Next, the adsorbent containers 11, 11, . . . containing new adsorbents are sequentially placed on the mounting table 13 using the chain block 12.
According to this deodorizing device, all of the above-mentioned problems can be solved. However, this deodorizing device still has the following problems. That is, if it is desired to increase the amount of air processed per unit time in this deodorizing device, it is necessary to increase the area of the adsorbent or increase the thickness of the adsorbent layer. However, in order to increase the adsorbent area, there is a drawback that the floor area of the deodorizing chamber 8 must be increased.Also, when the thickness of the adsorbent layer is increased, the flow resistance due to the adsorbent increases, and therefore the gas There is a drawback that the capacity of the exhaust blower connected to the exhaust port 4 must be increased.

Therefore, this invention can solve each of the above-mentioned problems, and can also increase the processing air volume per unit time without increasing the floor area of the deodorizing chamber or the flow resistance due to the adsorbent. This provides a deodorizing device in which the adsorbent placement part is of a cartridge type, and the container for storing the adsorbent is comprised of an outer cylinder made of a net-like body, and a net-like body arranged inside the outer cylinder. The container is composed of an inner cylinder formed by and a lid that closes off the upper part of the inner cylinder.

A mounting table 18 is installed on the bottom of this deodorizing chamber, and adsorbent containers 19, 19, . . . are placed on this mounting table 18. There are 11 sets in total, stacked in three tiers. In addition, below, 3
Each set of adsorbent containers 19 stacked in tiers is referred to as a container set 20. FIGS. 5A and 5B are a plan view and a front view of the adsorbent container 19, respectively, and as shown in these figures, the adsorbent container 19 has a hollow cylindrical shape. That is, this adsorbent container 19 has an outer cylinder 22 made of a net-like body such as a wire mesh or a punching plate.
It is composed of an inner cylinder 23 made of a similar net-like body, and an annular upper plate 24 and a bottom plate 25 that respectively close the upper and lower parts between the outer cylinder 22 and the inner cylinder 23. Further, as shown in FIG. 6, the upper plate 24 is formed with an adsorbent inlet 26 for introducing or discharging the adsorbent, and this inlet 26 is closed by a lid 27. In addition, in FIG. 5, reference numeral 28 is a frame, and 29 is a metal fitting for lifting.

FIG. 7 is an exploded perspective view of the container set 20, and as shown in this figure, the container set 20 includes three adsorbent containers 1.
9 and a lid 30 placed and fixed on top of the adsorbent container 19 at the top. Further, in this figure, reference numeral 18a is the upper plate of the mounting table 18, and this upper plate 18a is provided with a container guide 31, and a circular hole 32 is provided at a position corresponding to the hollow part of the adsorbent container 19. It is formed.

Next, in the upper part of the deodorizing chamber 17 shown in FIG.
3 are provided respectively, and these trolley beams 3
A trolley beam 35 is attached to the trolley beams 3, 33 via hand carriers 34, 34 so as to be movable in the left and right directions, and a chain block 36 is attached to the trolley beam 35 so as to be movable in the front and back directions (see FIG. 2). Further, a filter chamber 38 is connected to the right side of the deodorizing chamber 17. This filter chamber 3
A filter 39 is installed inside the filter 8, a gas introduction port 40 is formed on the top surface of the filter 39, and a door 41 for closing the filter exchange port is provided on the front surface of the filter 39. Then, the malodorous gas introduced from the gas inlet 40 passes through the filter 39 and is then led downward to the adsorbent containers 19, 19, . . . . A gas exhaust port 43 is formed at the rear left side of the deodorizing chamber 17, and one end of a duct 44 is connected to this gas exhaust port 43.
The other end of this duct 44 is an exhaust blower (not shown)
connected to the air intake. In addition, a maintenance entrance is provided at the front of the left side of the deodorizing chamber 17.
A door 46 is attached to this entrance. and,
The operator who replaces the adsorbent container 19 must open this door 4.

In the above configuration, the adsorbent containers 19, 19...
The foul-smelling gas introduced into the lower part of... is guided to the hollow part of each adsorbent container 19, passes through each adsorbent from this hollow part as shown by the arrow in FIG. 4, and exits from the gas outlet 43. is discharged to. Here, the adsorbent area is the sum of the areas of the inner cylinders 23 of each adsorbent container 19, 19..., and therefore the adsorbent area is much larger than that shown in FIG. It becomes possible to increase the processing air volume. In addition, the adsorbent area can be easily changed by changing the number of stages of the adsorbent container 19, and therefore even if the processing air volume changes, it can be dealt with immediately. Furthermore, even when the number of adsorbent containers is increased and the processing air volume is increased, the thickness of the adsorbent layer does not increase, and therefore the gas flow resistance due to the adsorbent does not increase significantly.

Next, when replacing the adhesive, the operator enters the maintenance space 47, attaches the fiber belt 50 to the metal fitting 29 of the adsorbent container 19 as shown in FIG. Hook it onto the fishing fitting 51, then pull up the fishing fitting 51, and then attach it to the chain block 36.

After all the adsorbent containers 19 have been carried out, the adsorbent containers 19 containing new adsorbents are sequentially set on the mounting table 18 using the chain block 36.

As explained above, according to the present invention, since the adsorbent placement section is of a cartridge type, the adsorbent can be replaced efficiently in a short time.

Almost no adsorbent dust is generated when the adsorbent is replaced, resulting in a better working environment, and surrounding walls and equipment are not contaminated by adsorbent dust.Maintenance equipment such as an electric hoist is installed above the deodorizing room. Benefits include: and no space required. Further, according to the present invention, since the adsorbent container is composed of an outer cylinder and an inner cylinder made of a net-like body, a bottom plate, and a lid, processing can be carried out without increasing the floor area of the deodorizing chamber or the flow resistance due to the adsorbent. This provides the advantage of being able to significantly increase the air volume, in other words, it provides the advantage of making the equipment more compact, and it also provides the advantage of being able to take immediate action even when the processing air volume changes.

That is, according to the present invention, the number of deodorizer containers can be adjusted by stacking deodorizer containers in multiple stages to form the container set 20, so the adsorbent area can be easily changed as necessary. Therefore, even if the processing air volume changes, it is possible to respond immediately.
