Embodiment Construction

[0025] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] Such as figure 1 As shown, the online analysis system for harmful gas detection in livestock and poultry farms of the present invention includes a sampling unit 1 , a purification unit 2 , an analysis unit 3 and a calibration unit 4 connected in sequence.

[0027] The sampling unit 1 includes a sampling pipe 11 , a first ball valve 12 , a second ball valve 13 and a jet pump 14 ; In this embodiment, the sampling pipe 11 is perpendicular to the ventilation duct to sample from the side; the jet pump 14 is a dry steam jet pump, and the steam with a pressure of 0.4 MPa is passed into the jet pump 14 through the second ball valve 13 . The steam provides sufficient sampling pressure and sampling temperature for livestock and poultry farms under various working conditions to ensure good fluidity of the gas.

Abstract

The invention discloses an online analysis system for monitoring harmful gases in a livestock and poultry farm. The online analysis system comprises a sampling unit, a purifying unit and an analytic unit connected in turn. Steam with a constant pressure is introduced into the sampling unit, is sent into the purifying unit by an injection pump and then is passed into the gas analytic unit. Through multiple times of filtration and dehumidification treatments, the gasses exhausted by a ventilation opening of the livestock and poultry farm can be stably sampled under various working conditions, and the sampled gasses automatically undergo dust removal, dehumidification drying, pressure and flow stabilization, fine filtration, flow measurement and quantitative analysis. Besides, measurement range calibration and zero point calibration are performed on a gas analyzer through a standard gas connected with the analytic unit to realize online calibration of the analysis system. The invention also discloses an online analysis method for monitoring the harmful gasses in the livestock and poultry farm. Through the online analysis system and the online analysis method, hydrogen sulfide, ammonia gas, carbon dioxide, carbon monoxide and methane exhausted by the ventilation opening of the livestock and poultry farm can be accurately and reliably detected and analyzed online.

Description

technical field [0001] The invention relates to an online real-time monitoring system, in particular to an online analysis system for real-time monitoring of harmful gases in livestock and poultry farms. Background technique [0002] Hydrogen sulfide, ammonia, carbon dioxide, carbon monoxide and methane are common harmful gases in livestock and poultry farms. Excessive concentration of these harmful gases will not only threaten the health of livestock, poultry and people, but also have a great impact on the surrounding environment. Taking ammonia as an example, livestock and poultry are particularly sensitive to ammonia. Low concentrations of ammonia can cause inflammation of the conjunctiva of livestock and poultry, upper respiratory tract mucosal hyperemia, edema, and increased secretions. Sustained high concentrations of ammonia can damage the respiratory tract of livestock and poultry. Epithelial tissue destroys its natural barrier, reduces resistance to bacteria and vi...
