Description

Feed production exhaust treatment system

Technical Field

The utility model relates to a waste gas treatment technical field especially relates to a fodder production exhaust treatment system.

Background

The feed has high requirements on protein content, and squid paste, fish meal, fish soluble paste and the like are common raw materials in the processing process. From conventional physical knowledge, it is known that the higher the temperature, the more vigorous the molecular motion, the more easily the odor is spread and the higher the concentration. In the granulating or puffing process, the squid paste and fish meal are heated and cured, and the fishy smell of the high-protein substances is easy to be emitted in the heating and curing process. The waste gas discharged in the processing process of the feed has the characteristics of large waste gas amount, high concentration, high temperature (about 70-90 ℃), high humidity (more than 90%), large dust concentration and the like. Although the dedusting process in the cooling and drying sections is basically cyclone dedusting (commonly called as cyclone brake), powder leakage or instant discharge of a large amount of dust is often caused by material blockage of an air seal, improper operation, mechanical failure and the like. Therefore, if the waste gas with odor and dust generated in the production and processing processes of the feed is directly discharged to the atmosphere, the pollution to the surrounding environment can be caused, and the health of people is seriously threatened.
