Conventional physical and chemical deodorization techniques include combustion methods, catalyst methods, chemical absorption acid methods, ozone oxidation methods, adsorption methods, etc., but each of these methods is not a versatile technology. There is no method that can remove bad odors, and each has its own advantages and disadvantages.One of these adsorption methods, activated carbon adsorption method, is widely used because it is a dry method and is easy to operate. When necessary, it is often used in combination with a wet method (chemical absorption oxidation method, etc.) for finishing and deodorizing.

ところで活性炭吸着方式は、比較的高分子の臭気成分を

By the way, the activated carbon adsorption method is suitable for deodorizing gases that contain relatively high-molecular odor components, but when moisture or mist is adsorbed on the surface of the activated carbon, the surface of the activated carbon is covered with a liquid surface and the odor components are removed. It stops adsorbing. Therefore, before the gas to be treated enters the activated carbon adsorption tower, it is necessary to remove moisture or mist in the gas by pretreatment. Furthermore, activated carbon has a large deodorizing ability (adsorption ability) when the temperature is low and the humidity is low, but the deodorizing ability decreases when the temperature is high and the humidity is high.

Therefore, in the conventional activated carbon adsorption method, before the gas to be treated enters the adsorption tower, a mist separator is used to remove mist of more than 10 Nm, and the gas to be treated is heated to 4 to 8℃ using a heater.
The temperature was raised and the relative humidity was lowered.

〔発明が解決しようとする問題点〕[Problem that the invention seeks to solve]

In the conventional activated carbon adsorption method as described above, the gas to be treated is heated before entering the adsorption tower, so the adsorption tower cannot adsorb odor components at low temperatures. There is a problem in that an extra energy cost is required to raise the temperature of the gas to be treated by 4 to 8° C., and the energy cost accounts for a large proportion of the running cost, resulting in an increase in the running cost.

The present invention was made to solve these problems, and its object is to provide a deodorizing device that adsorbs treated gas with activated carbon at low temperature and low humidity.
