Independent combustible gas detection apparatus

Abstract

The invention discloses an independent combustible gas detection apparatus. The independent combustible gas detection apparatus comprises a gas collection tank, wherein an air inlet is arranged at a lateral part of the gas collection tank, the air inlet is positioned outside the gas collection tank and communicated with a filter tube; a connection bench, wherein a pipeline is fixedly arranged in the connection bench; a casing, wherein a top board is arranged at the top of the casing, baffle rods are symmetrically and fixedly arranged at two sides of the top board; an analysis apparatus which comprises a first detection chamber, a second detection chamber and a third detection chamber vertically and downwardly and fixedly arranged at the top board, and sensors are fixedly arranged at the top of the first detection chamber, the second detection chamber, and the third detection chamber; a purifying case, wherein several steel plates are horizontally and fixedly arranged at internals up and down in the purifying case, and the steel plates are filled with a gas purifying material; and a cycle apparatus which comprises a gas case, a first exhaust pipe and a second exhaust pipe fixedly arranged at a side wall of the casing. The independent combustible gas detection apparatus has the advantages of simple structure and high data detection accuracy, the purified gas is used for repellingthe residual gas in the independent combustible gas detection apparatus, and the protection effect on the sensor is realized.

Description

technical field [0001] The invention relates to the technical field of gas detection. More specifically, the present invention relates to a self-contained combustible gas detection device. Background technique [0002] With the serious decline of air quality and the frequent occurrence of toxic gas leakage incidents, more and more people pay attention to the detection and analysis of gas composition and concentration. Nowadays, gas detection devices are usually used to detect the presence of harmful gases in a certain space. Composition and concentration, commonly used gas detection devices usually include a sensor for sensing the composition and content of the gas and a display for displaying the detection results. The sensitivity of the sensor is high, but its sensitivity is greatly affected by the external environment. [0003] Traditional gas detection devices are mostly single-gas detectors, which detect a single type of gas, and few gas detection devices involve the ...

The sensitivity of the sensor is high, but its sensitivity is greatly affected by the external environment

[0003] Traditional gas detection devices are mostly single-gas detectors, which detect a single type of gas, and few gas detection devices involve the treatment of residual gas remaining in the device after detection. Residual gas will not only affect the sensitivity of the sensor , reduce the accuracy of the next test result, and if the gaseous gas is detected, it will cause certain harm to the staff
