Livestock and poultry breeding waste gas treatment device and deodorizing process thereof

Abstract

The invention discloses a livestock and poultry breeding waste gas treatment device and a deodorizing process thereof. The device mainly includes low-pressure exhaust fans, a sewage collection pit, annular water spraying devices and a biological deodorization device. The low-pressure exhaust fans are multiple and are mounted in exhaust pipes near an air outlet of a livestock and poultry farm. Theannular water spraying devices are mounted in the exhaust pipes at air outlets of the low-pressure exhaust fans. An A part of the sewage collection pit is connected to the annular water spraying devices through water pump pipelines, and a B part is connected to a spraying system of the biological deodorization device through a lifting pump pipeline. The air outlets of the low-pressure exhaust fanscommunicate with the biological deodorization device through the exhaust pipes. The middle parts of the exhaust pipes communicate with the A part of the sewage collection pit through pipelines. The bottom of the biological deodorization device communicates with the A part of the sewage collection pit through a pipeline. The device of the invention has the advantages of low energy consumption, strong controllability, good deodorization effect and simple and efficient process during operation.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a livestock and poultry breeding waste gas treatment device and a deodorizing process thereof. Background technique [0002] In recent years, in order to reduce the biosecurity risks brought by retail and small-scale livestock and poultry breeding sites, my country has provided a series of preferential policies for standardized-scale livestock and poultry breeding, making livestock and poultry farming gradually move towards a planned and intensive production model. It has promoted the development of the entire industry and brought huge economic benefits to the society. However, the environmental pressure brought about by the highly intensive development of livestock and poultry and the large amount of breeding will also increase, and the pollution situation will become increasingly severe, especially the problem of air pollution. Harmful gases such as ammonia, hydroge...

AI Technical Summary

Problems solved by technology

However, there are several problems in the existing biological method applied to the treatment of waste gas from livestock and poultry breeding: (1) The power source of the system is a high-power blower, which consumes a lot of energy during operation; (2) The wind pressure generated by the blower is high and cannot be directly For internal air replacement in livestock and poultry breeding plants

In order to ensure the normal and healthy growth of livestock and poultry, it is necessary to add an additional low-pressure air supply system, which will undoubtedly increase the cost; (3) The amount of exhaust gas produced in different periods and seasons of the livestock and poultry growth process is different, and the area with adjustable air volume of the blower is used Smaller, in order to ensure compliance with emission standards, high power must be used to process lower exhaust gas volumes, thus increasing operating costs
