In FIG. 1, reference numeral 41 is a replenishment pipe for deodorizing liquid to the deodorizing liquid tank 5, and reference numeral 42 is a discharge pipe for removing waste liquid and sludge from the deodorizing liquid tank 5.

The deodorizing device of the illustrated embodiment operates as follows.

When the motors M ₁ , M ₂ and the pressure pump 26 are driven, the hollow shafts 15 , 16 , 31 , 32 rotate while spouting the deodorizing liquid from the small holes 20 formed on the entire circumference of the shafts. The deodorizing liquid that has been removed is
8, 19, 35, 36, and is scattered in a mist form, filling the boxes 1, 6, and riding on the rotating airflow generated by the rotation of each brush, each flat brush 29, 30, It also adheres and accumulates on the brush surfaces 37 and 38.

In this state, when the foul-smelling exhaust gas, etc. is forced into the box 1 of the first unit from the inlet 2, the exhaust gas, etc. mixes with the mist of the deodorizing liquid, and the brush 18,
It is forcibly rotated in the directions of arrows A and B while being stirred by Group 19, and between the hollow shafts 15 and 16, it becomes a high-speed flow as shown by arrows A' and B' due to the action of brushes 18 and 19. It collides with the flat brush 29. The collided exhaust gas, etc. flows again in the directions of arrows A and B by the rotation of the brushes 18 and 19, but most of the exhaust gas flows in the direction of arrows B by the rotation of the brush 19, and flows into the hollow shaft of the second unit. 31 brushes 35
Due to the action of the brush 19 of the first unit, the flow becomes a high-speed flow as shown by arrows ``L'' and ``A'' and collides with the flat brush 30. The exhaust gas, etc. undergoes the action explained above also in the second unit, and flows to the final end as shown by the arrows C, D, H, and F, and flows through the opening 1.
1. It is released into the atmosphere through the exhaust duct 13 and the exhaust stack 14.

In the above-described operation, exhaust gas, etc. is flowed into an atmosphere in which a deodorizing liquid is constantly ejected and diffused in the form of a mist, and in that atmosphere, the brushes 18, 19, 35, and 36 moistened with the deodorizing liquid are stirred, Flat brush 29, 3 also moistened with deodorizing liquid
0, 37, and 38, the gas-liquid contact ratio is extremely high, and an excellent deodorizing effect is exhibited.

The ejected deodorizing liquid adsorbs odor components, dust, etc. contained in exhaust gas, etc., flows down into the deodorizing liquid tank 5, is again forced to be fed by the pressure pump 26, and is ejected.

In the illustrated example, two units are combined, but if the amount of exhaust gas, etc. is small, the concentration is low, and the odor is light, it may be sufficient to use only one unit; When the amount and concentration of odor is large and the odor is strong, the purpose of deodorization can be achieved by combining multiple units such as 3 or 4 units.

The deodorizing device according to the present invention has the configuration described above,
The deodorizing liquid is sprayed out to form a mist, the brush is rotated in an atmosphere filled with this, and the exhaust gas, etc. is mixed with the mist, and the brush or flat plate is moistened with the deodorizing liquid. Since it is brought into contact with the brush and collided with it, it has the effect of significantly increasing the gas-liquid contact rate and achieving a sufficient deodorizing effect.

Furthermore, it has a relatively simple structure, can be supplied at low cost, and has the advantage of being easy to maintain and manage.

Furthermore, since the combined structure of the box, the hollow shaft with a brush, and the flat brush constitutes one unit, the required number of units can be combined depending on the amount, concentration, and type of exhaust gas, etc. to be treated. It has the advantage that a single model can be used for a variety of purposes.
