一种用于检测筒仓内可燃气体浓度的设备
摘要：
本发明公开了一种用于检测筒仓内可燃气体浓度的设备，该设备包括：气体采集装置，该气体采集装置包括用于从至少一个筒仓中采集气体的至少一个采气头(11)、气泵(12)、第一电磁换向阀(13)，所述至少一个采气头(11)经由管路与所述气泵(12)的入口连接，该气泵(12)的出口连接到所述第一电磁换向阀(13)的入口；气体分析装置(20)，该气体分析装置(20)用于接收从所述第一电磁换向阀(13)的出口输出的由所述至少一个采气头(11)采集的气体，检测该气体中可燃气体的成分及浓度，并输出指示该成分及浓度的信号。本发明提供的设备能够检测筒仓内可燃气体的浓度。
摘要（英）：

The invention discloses equipment for detecting the concentration of combustible gas in a silo. The equipment comprises a gas collection device and a gas analysis device (20), wherein the gas collection device comprises at least one gas collection head (11) for collecting gas from at least one silo, a gas pump (12) and a first electromagnetic directional valve (13); the at leas one gas collection head (11) is connected with the inlet of the gas pump (12) through a pipeline; the outlet of the gas pump (12) is connected with the inlet of the first electromagnetic directional valve (13); the gas analysis device (20) is used for receiving the gas output by the outlet of the first electromagnetic directional valve (13) and collected by the at least one gas collection head (11), detecting the composition and concentration of the combustible gas in the gas, and outputting a signal indicating the composition and concentration. The equipment provided by the invention can detect the concentration of the combustible gas in the silo.
