Forage processing peculiar smell treatment method and equipment

Abstract

The invention discloses a forage processing peculiar smell treatment method and an equipment. The forage processing peculiar smell treatment method comprises following steps: S1, spray washing, wherein in a pre-washing tank, water spraying washing is adopted to remove water soluble smell substances in waste gas generated in forage processing process, and adjust the physicochemical properties of the air; S2, biofiltration, wherein air is introduced into a biofiltration tank from the bottom of the biofiltration tank, is driven to move upward uniformly along a first air distribution plate arranged at the middle part of the biofiltration tank, and is contacted with a biological filling material with a certain humidity on the first air distribution plate fully, so that the smell substances are absorbed by the biological filling material firstly, and then are degraded by microorganisms in the biological filling material via oxidation, smell is eliminated, and deodorizing of waste gas is realized; and S3, UV photolysis, wherein a UV photolysis device is used for further deodorizing of air discharged from the biofiltration tank, and then the air is discharged to the outside using a rear-induced draught fan.

Description

[0001] Technical field: [0002] The invention relates to a feed processing peculiar smell treatment process and equipment thereof. [0003] Background technique: [0004] Feed processing plants produce peculiar smell and malodorous gas due to anaerobic fermentation in the process of drying, stacking and cooling. Domestic and foreign treatment technologies for malodorous gas mainly include: activated carbon adsorption method, thermal oxidation method, physical chemical method, low temperature plasma method, plant Extraction method, UV photolysis method, biological method, etc. [0005] Each deodorization method has different characteristics, and has its scope of application and limitations. Chemical washing can achieve a good deodorizing effect, but it has defects such as high operating costs, complicated follow-up treatment, and secondary pollution, and is rarely used now; chemical deodorization technologies such as air oxidation and chemical oxidation do not have high operat...

AI Technical Summary

Problems solved by technology

Chemical washing can achieve a good deodorizing effect, but it has defects such as high operating costs, complicated follow-up treatment, and secondary pollution, and is rarely used now; chemical deodorization technologies such as air oxidation and chemical oxidation do not have high operating costs, Disadvantages such as complex management and operation are secondary pollution and fewer types of gas to be processed.
