Abstract

The invention relates to the technical field of gas detection. The invention discloses a gas detection device and a gas detection method. The detection device comprises a mixer, to-be-detected gas conveying equipment, catalysis assisting gas conveying equipment and a catalytic combustion sensor. A flow guide area and a mixing area are arranged in the mixer; a premix area, a first gas guide area and a second gas guide area are formed in the mixing area; the to-be-detected gas conveying equipment is connected with the first gas guide area, the catalysis assisting gas conveying equipment is connected with the second gas guide area and can convey catalysis-assisting gas into the premix area, the to-be-detected gas and the catalysis-assisting gas are mixed in the premix area to form mixed gas,and the mixed gas is guided to the catalytic combustion sensor through the flow guide area. The detection method comprises the following steps: S1, conveying to-be-detected gas and catalysis-assistinggas into a mixer for mixing to obtain a to-be-detected gas sample; and S2, detecting the to-be-detected gas sample through a catalytic combustion sensor to obtain a combustible gas concentration value.

Description

technical field [0001] The invention relates to the technical field of gas detection, in particular to a gas detection device and a detection method. Background technique [0002] In order to ensure safety in industrial production and testing, it is necessary to detect the concentration of some gases in the flue used in industrial production. When the traditional technology detects the gas concentration of the gas in the flue, infrared gas detectors are often used. However, due to the high gas concentration in the flue during use, it is easy to cause the gas concentration data detected by the infrared gas detector to be different from the real gas. Concentration produces a large error. Contents of the invention [0003] The first object of the present invention is to provide a gas detection device, so as to overcome the problem in the prior art that direct detection of high-concentration gas is prone to large errors. [0004] In order to achieve the above object, the bas...
