Abstract

畜禽用多功能气体分析仪属畜禽气体分析技术领域,本发明氮气袋与6个电磁阀入口连接;6个电磁阀出口与另6个电磁阀常开口连接;6个气体回流进气管一端与各6个发酵罐、呼吸代谢室入口连接;6个气体回流进气管另一端与6个电磁阀常闭出口连接;6个气体回流出气管一端与各6个发酵罐、呼吸代谢室、畜禽舍出口连接;传感器组输出端与微机连接;传感器组进气口分别与6个电磁阀出气口连接;传感器组的出气口经流量计、微型气泵、气压表分别与6个电磁阀的进气口连接;6个电磁阀的常闭进气口连接;本发明可6通道同时在线测定瘤胃液体外发酵、动物呼吸代谢,监测畜禽舍环境中二氧化碳、甲烷和氨气含量,还可进行甲烷、二氧化碳减排试验。
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.
