Description

Chemical washing and deodorizing apparatus

The present invention relates to a chemical cleaning and deodorizing apparatus, and more particularly, to a chemical cleaning and deodorizing apparatus for efficiently controlling deodorization of malodorous gas according to malodor concentration.

In general, odor refers to an unpleasant odor that can be detected by humans, and there are many types of source materials of odor that are normally generated in the surrounding environment. Odor is caused by the complex action of various odor substances, and each source is gaseous pollutants such as complex odors and volatile organic compounds from sewage treatment plants, sanitary treatment plants, excreta treatment plants, and petrochemical-related plants, except for general plants. This is a problem, and also food waste recycling facilities, which have been a continuous problem in recent years, are mentioned.

In recent years, the number of complaints due to such odors is increasing, and it is a reality that the facilities that are the source of the odor are having difficulties in responding to the surroundings, so efforts are being made from various angles on how to remove the odor. Currently, 22 specific odor substances such as ammonia, methyl mercaptan, and hydrogen sulfide are designated and managed as odor control substances in Korea.

Methods for removing these odor substances are largely divided into physical and chemical odor removal and biological odor removal. Physical odor removal includes washing with water or adsorption and removal with an adsorbent such as activated carbon, zeolite, silica gel, or activated clay. , Chemical odor removal methods include mastering and neutralization methods, and biological methods include biofilters. Among these, the most widely used method is a method that combines physical odor removal and chemical odor removal, and the application of various types of complex deodorization methods that combine additional technologies with acid/alkali chemical cleaning methods to improve deodorization efficiency cases are increasing.
