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
Inside, for example, a plurality of gas filtration structures consisting of a metal mesh 24 having a mesh size of 2 to 25 mm and a filter plate 25 having an appropriate thickness are provided, and the gas filtration structure is guided through the filtration structures to the inlet tube 6 to the main body of the deodorizer. Is becoming In this case, the cross-sectional shape when the first half 20 and the second half 21 of the inlet side chamber 2 are combined is an ellipse 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 uniformly 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 side drum 2 at high speed and high pressure separates smoke particles and solid matter such as tar while deodorizing. 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 device 9 through the deodorant 34 as a clean gas in which almost no odor and offensive odor are removed, and the pressure is reduced only by the inlet side fan device 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 has been conventionally required, but it has been confirmed that the deodorizer can be effectively deodorized in most of the odor-producing environments that have been left unattended because of its small scale. As the malodorous component, for example, ammonia 30%, toluene 40%, methanol 50%, acetic acid 30 to 32%, methyl ethyl ketone 40%, butyl acetate 50%, butanol 60%, etc. are completely converted to the contents in the aqueous solution. It was neutralized and deodorized, and when garlic was crushed and heated at the inlet of the deodorizer, it was able to function completely.

[0020]

As described above, the present invention enables extremely effective deodorization. Further, due to its characteristic structure, (1) Since it has a double structure, it does not explode even if it is ignited by static electricity when treating flammable gas odor. (2) Since the casing for the deodorant is a cartridge type for each unit structure, repair and replacement are extremely easy. (3) Easy to assemble. (4) It should be noted that the deodorant replacement period is 3000 to 10
6 to 10 months at 10,000 ppm, 10,000 to 30,000
It was confirmed that it is good if it is within 6 months in ppm.
