[0003]

That is, the source of malodor is not limited to large-scale factories, but is also a drying furnace or heating furnace in small-scale factories, processing in food processing factories, animal husbandry, and even malodors from hospitals, etc. As for the above, deodorization of these substances is being urgently required.

The present invention is intended to provide a simple device for effectively removing the odor emitted from the above-mentioned relatively small-scale odor source.

[0005]

To achieve the above object, the present invention provides a tubular frame-shaped casing unit having connecting flanges on the inlet side and the outlet side, and a barrel that fits in the tubular frame of the casing unit. It has a wall, and at least one of both ends that are substantially open is an end flange that is joined to at least one of the connecting flanges, and for protection facing each open end in the cylindrical wall. At least one unit structure consisting of a mesh and a filter plate adjacent to the inside of the mesh, and a cartridge unit consisting of a filter unit filled with a deodorant is used, and each unit structure is flanged to the front and rear structures. A deodorizer main body is formed, and an inlet side chamber for pressurizing a gas to be treated is connected to one end opening of the main body, and the inlet side chamber has its axis centered on the axis of the deodorizer body. Made from the matching caused to the drum-shaped,
A spiral guide plate is provided in the first half drum portion having an air inlet for treatment in the outer peripheral portion, and the latter half drum portion detachably connected to the first half drum portion is further provided with an inlet of the deodorizer body connected to this latter half drum portion. Is equipped with a pair of at least one stage mesh plate and filter plate facing each other, and the outlet side chamber has a drum shape with its axis aligned with the axis of the main body of the deodorizer. The first half drum part detachably connected to the first half drum part is equipped with a guide plate having a ventilation hole in the peripheral edge part, and the rear half part having the rear end edge of the first half drum part and the peripheral part removably joined to the peripheral edge of the guide plate. A high-speed deodorizer is constructed by inserting a tip of an exhaust pipe into a drum portion and filling a space inside the drum surrounding the exhaust pipe with a deodorant.

The present invention also has the following basic configuration.
It is characterized in that a high pressure air flow compulsion means composed of a multi-stage fan device is connected to at least one of the air inlet of the inlet side chamber and the rear portion of the exhaust tube inserted into the outlet side chamber.

[0007]

According to the basic configuration of the present invention, when the introduced gas having an odor passes through each unit structure including the casing unit and the cartridge unit, the filled deodorizing agent completely removes the organic gas component and the offensive or offensive odor. Can be removed. In this case, since the unit structure is a double structure, by making the tubular frame-shaped casing unit made of metal such as stainless steel, the highly flammable gas component such as the gas emitted from the organic solvent may be affected by static electricity. Even if it catches fire
It is possible to ensure the safety that it does not explode due to its shield effect.

Moreover, since each unit structure is easily repaired, the deodorant and the filter can be replaced in a short time.
It has an advantage that it can be easily assembled regardless of the arrangement of the whole apparatus such as vertical type or horizontal type.

Further, by using the inlet side drum, the introduced gas is guided and accelerated as a swirl flow, and at the same time, various smoke particles and dust tar-like substances are passed through the filter and the protective net on the latter half side of the drum, so that the deodorizer main body. It is separated and blocked by the time it enters, and the final gas purification can be performed by using the outlet drum.

The deodorizer structure is inserted and fastened between the deodorizer and 5a, and is sequentially added.

The inlet side chamber 2 comprises a front half drum portion 20 as shown in FIG. 8 and a rear half drum portion 21 as shown in FIG. In FIG. 8, a spiral guide plate 22 is formed in the first half drum portion 20, and the gas to be processed fed from the gas inlet 23 at a high pressure from the multi-stage fan device is guided and accelerated in a spiral manner, so It guides the latter half drum portion 21 while separating the solid matter. Second half drum section 21
For example, a plurality of gas filtration structures including a wire mesh 24 having a mesh size of 2 to 25 mm and a filter plate 25 having an appropriate thickness are provided in a plurality of stages, and the inlet cylinder 6 to the deodorizer body is passed through these filtration structures.
It is supposed to lead to. In this case, the inlet chamber 2
The cross-sectional shape of the first half 20 and the second half 21 is an elliptical shape as shown in FIG.

The gas substantially deodorized through the deodorizer main body 3 is introduced into the outlet side chamber 8 through the outlet cylinder 7 having a gas filtering and deodorizing structure similar to the unit structure. The outlet side chamber 8 is composed of a front half drum portion 26 and a rear half drum portion 27 which are integrated so as to have an elliptical cross-sectional shape similar to that of the inlet side chamber 2, and the joining portion between them is as shown in FIG. The shade-shaped guide plate 28 is inserted. The shade-shaped guide plate 28 is composed of an obtuse-angled cone portion 29 at the center and an annular flat plate portion 31 having a large number of vent holes 30 formed around the obtuse-angled cone portion 29. In this case, the apex of the conical portion 29 is aligned with the axial center of the deodorizer main body 3 in the first half drum portion 26, so that the gas discharged from the outlet cylinder 7 is evenly spread and moved to the peripheral portion by the conical portion 29. And vent 3

The inlet cylinder 33 of the multi-stage fan unit 9 having a large number of ventilation holes 32 is fed into the inside of the inside 7 of the drum 7, and the tip of the inlet cylinder reaches the inside of the drum front half portion 26. A deodorant 34 for final deodorization assistance is filled in the rear portion of the shade-shaped guide plate 28 of the drum 26 and the outside of the inlet cylinder 33 in the drum rear half portion 27.

Since the high-speed deodorizer of the embodiment is constructed as described above, the gas to be treated introduced into the inlet drum 2 at high speed and high pressure is capable of deodorizing while separating solid matter such as smoke particles and tar. Deodorization and dust removal are sequentially performed through each unit structure in the container body 3. Finally, when it reaches the outlet-side drum 8, it is introduced into the outlet-side multi-stage fan unit 9 as a clean gas from which almost no odor and offensive odor has been removed, and is introduced into the outlet-side multi-stage fan unit 9 to reduce the pressure only by the inlet-side fan unit 1. Can be discharged to the outside air while being supplemented by suction force. In this way, when the gas to be processed passes through the inside of the deodorizer main body 3 at high pressure and high speed, the temperature becomes considerably high due to compression and friction, and the adsorption and separation of the malodorous component and the foreign matter to the deodorant is promoted.

Experimental Results A high-speed deodorizer having a substantially six-stage structure as in the embodiment was constructed, and the motor output on both the inlet side and the outlet side was 2.2 KW, the rotation speed was 2850 to 3450 rpm, and the static pressure was 810. ~ 1370mHg, and wind speed 7m / sec ~ 16
As a result of driving at m / sec, a deodorizer was conventionally required, but it was confirmed that the deodorizer can be effectively deodorized in most odor-producing environments that have been left unattended because of its small scale. Examples of malodorous components are ammonia 30%, toluene 40%, methanol 50%, acetic acid 30-32%, methyl ethyl ketone 40%, butyl acetate 50%, butanol 60%, etc. It was neutralized and deodorized, and when garlic was crushed and heated at the inlet of the deodorizer, it was able to function perfectly.

[0018]
