System and method for controlling odor and smoke in livestock and poultry farms

Abstract

Provided are a system and a method for livestock and poultry farm odor and flue gas treatment, comprising a solid high temperature aerobic fermentation system, a liquid high temperature aerobic fermentation system fermentation odor and boiler combustion flue gas treatment system (002), and a detection control system. The solid high temperature aerobic fermentation system fermentation odor treatment system (001) comprises an odor heat exchange condenser A, a draft fan (102) and a biological deodorization filter (103). The liquid high temperature aerobic fermentation system fermentation odor and boiler combustion flue gas treatment system (002) comprises a multi-functional biomass combustion boiler (202), a three-way electrical regulating valve (203), an aeration fan (204), an odor heat exchange condenser B, a draft fan (205) and a biological deodorizing filter (206). Sensors of the detection control system are provided in each of the systems to detect key parameters, and to detect the control system's connection to and control of the described systems.

Description

technical field [0001] The invention belongs to the technical field of pollution control, and specifically relates to a system and method for controlling odor and smoke from livestock and poultry farms. , placenta, domestic garbage and straw and other rural organic waste pollutants, as well as the flue gas produced by the combustion of fossil fuels. Background technique [0002] In the process of fermenting and composting livestock and poultry manure in livestock and poultry farms, under aerobic or anoxic conditions, the organic components in the material, such as protein, are decomposed by microorganisms, producing a large amount of toxic and harmful odor gases. Disposal and direct discharge into the atmosphere will seriously affect the atmospheric environment of the composting plant and its surroundings. Therefore, the deodorization project in the composting process has become an indispensable part of the high-temperature composting process of organic solid waste. [000...

AI Technical Summary

Problems solved by technology

[0005] There are many technologies for controlling odor and combustion flue gas, such as absorption and adsorption, incineration, chemical conversion, condensation and biological methods, but among these methods, the most economical and effective is the biological deodorization method, the biological deodorization method It is an odorless and harmless process method, that is, using the microbial flora with deodorization function to convert hydrogen sulfide, reduced sulfide and other odorous substances in the waste gas, with high removal rate, low operating cost, and easy operation and management. It is simple and does not produce secondary pollution. However, the deodorization effect of the biological deodorization method depends on the activity of deodorizing microorganisms. Too high or too low air intake temperature for deodorization will affect the growth and reproduction of microorganisms, thereby reducing the deodorization effect. When the deodorizing intake air temperature is higher than 40°C or lower than 15°C, the growth and reproduction of deodorizing microorganisms will be inhibited; when the deodorizing intake air temperature is higher than 60°C, a large number of deodorizing microorganisms will die, and the deodorizing effect will be lost
