Multifunctional gas analyzer for livestock

Abstract

The invention discloses a multifunctional gas analyzer for livestock, and belongs to the technical field of livestock gas analysis. In the multifunctional gas analyzer provided by the invention, a nitrogen sack is connected with inlets of six electromagnetic valves, and outlets of the six electromagnetic valves are connected with normal open holes of another six electromagnetic valves; one ends of six gas backflow air inlet pipes are connected with inlets of six fermentation tanks and respiratory metabolism chambers, and the other ends of the six gas backflow air inlet pipes are connected with normal closed outlets of the six electromagnetic valves; one ends of six gas backflow air outlet pipes are connected with six fermentation tanks, the respiratory metabolism chambers and livestock room outlets, an output end of a sensor group is connected with a microcomputer, and an air inlet of the sensor group is connected with air outlets of the six electromagnetic valves; an air outlet of the sensor group is respectively connected with air inlets of the six electromagnetic valves through a flowmeter, a minitype air pump and a barometer, and the normal closed air inlets of the six electromagnetic valves are connected. The multifunctional gas analyzer provided by the invention has the advantages that six channels can simultaneously on-line measure rumen liquor invitro fermentation and animal respiratory metabolism, the contents of carbon dioxide, methane and ammonia in a livestock room environment are monitored, and methane and carbon dioxide emission reduction tests are performed.

Description

technical field [0001] The invention belongs to equipment for on-line monitoring of animal exhaled gas (oxygen consumption, carbon dioxide production, methane production), gas produced by external fermentation of rumen liquid (carbon dioxide production, methane production) and for monitoring the air environment in livestock and poultry houses. The technical field of oxygen, carbon dioxide, methane and ammonia, specifically related to the gas circuit device of the system. Background technique [0002] In the past, the on-line determination of the amount of oxygen consumption, carbon dioxide and methane produced in the exhaled gas of animal respiratory metabolism required a special gas analyzer; the gas produced by the external fermentation of rumen liquid mainly included the amount of carbon dioxide and the amount of methane produced, which also required a specific dedicated It is used to monitor the carbon dioxide, methane and ammonia in the air environment in the livestock ...

AI Technical Summary

Problems solved by technology

[0003] At present, there is no multifunctional gas analyzer for livestock and poultry that can be used to monitor (1) the oxygen consumption, carbon dioxide and methane production of animal respiratory metabolism and exhaled gas on line; (2) measure the carbon dioxide produced by external fermentation of rumen liquid (3) Monitor the ambient (harmful gas) carbon dioxide, methane and ammonia levels in the air in livestock houses
