Abstract

The invention discloses an explosion-proof high and low temperature damp and heat test device, relating to the technical field of high concentration combustible gas sensor online climate testing. Thedevice mainly comprises four parts: an explosion-proof box body, an indirect heating refrigerating system, an air exchange system and a control circuit, wherein the explosion-proof box body is an inside-outside dual-layer shell, a box door is provided with an observation window and a security lock, the observation window is sealed for many layers, an LED lamp is installed in the box body, an explosion-proof methane gas sensor and a temperature sensor are installed in the LED lamp, the indirect heating refrigerating system comprises an evaporator, a humidifying water tray and a refrigerating unit, a heating unit, a humidifying unit, and a silicon oil tank, the air exchange system comprises an air supply system supplying air for the interior of the explosion-proof box body and an exhaust fanat the top of the box body, and the control circuit is arranged at the back of the box body and is a circuit safe in nature. The explosion-proof high and low temperature damp and heat test device protects operators in test, makes online environment measurement test more reliable, and controls methane gas concentration so as not to cause explosion.

Description

technical field [0001] The invention relates to the technical field of high-concentration combustible gas sensor online climate environment test, in particular to an explosion-proof high and low temperature damp heat test device. Background technique [0002] With the wide application of coalbed methane, the mining of coalbed methane requires more and more large-scale and high-concentration methane sensors. Environmental performance testing is an important technical indicator of methane sensors. How to complete the testing of methane sensors in a safe, accurate and standardized manner Environmental performance testing plays a vital role in its quality. [0003] In the standards of "AQ6204-2006 Thermal Conductivity High Concentration Methane Sensor for Gas Drainage", "AQ6206-2006 High and Low Concentration Methane Sensor for Coal Mine", and "AQ6211-2008 Non-dispersive Infrared Methane Sensor for Coal Mine", the low temperature working test and The high-temperature work test ...
