Multi-point-location on-line automatic collection system for gas in livestock and poultry field area

Abstract

The invention relates to a multi-point-location on-line automatic collection system for gas in a livestock and poultry field area. The automatic collection system comprises a plurality of groups of gas production heads, a plurality of groups of gas inlet pipelines, a gas collection box and a gas backwashing system. Gas samples at all monitoring point locations of a farm enter the gas inlet pipelines through the gas production heads arranged at the top end of a telescopic supporting frame and then are conveyed into the gas collection box through the gas inlet pipelines, and the collected gas samples are switched in a gas sampling box through a gas inlet switching valve and then sequentially enter a gas monitoring instrument. According to a multi-point-location on-line automatic collection method for gas in a livestock and poultry field area, automatic online continuous collection of gas samples at a plurality of monitoring point locations in a livestock and poultry farm can be realizedautomatically and real-time continuous measurement of a gas on-line monitoring instrument can be realized. Compared with a conventional method, the method has the advantages that the gas collection process of the livestock and poultry farm is simplified, labor is saved, and the gas detection precision is improved.

Description

technical field [0001] The invention belongs to the technical field of livestock and poultry breeding environment monitoring, and relates to a multi-point automatic collection system for online gas monitoring in livestock and poultry farms. Background technique [0002] With the rapid development of intensive livestock and poultry breeding industry, more and more attention has been paid to the air pollution caused by livestock and poultry breeding. Livestock and poultry farms generally have a large area, including pens, manure sheds, sewage treatment areas and other facilities. The pens can be divided into different areas such as exhaust area, window area, air intake area, and corridor area. There are many types of gas pollutants, including ammonia, hydrogen sulfide, nitrous oxide, VOCs, PM2.5, PM10, etc. In order to clarify the characteristics of pollutants in livestock and poultry farms and evaluate the degree of air pollution caused by livestock and poultry farming, It i...
