Problems solved by technology
If there is too much moisture and dust in the sampling gas path, it will increase the wear of the pump, and it will also cause the pump to be stuck and damaged
At the same time, moisture and dust in the gas path will also easily damage various sensors in the sampling instrument and reduce the service life
Conventional desiccant water removal method, after the desiccant absorbs water, needs to be replaced regularly by the sampler or reused after drying the desiccant, which is inconvenient to use

The invention discloses a gas filtering device for gas detection, which comprises a driving mechanism, a dehumidification mechanism and a dust removal mechanism, the dehumidification mechanism comprises a plurality of water absorption permeable plates, a turntable I, a plurality of through holes I, a moisture absorption area, a drying area and a shell I. The turntable I is arranged in the shell I, and the through holes I distributed in a circumferential shape are formed in the turntable I; a water absorption and ventilation plate is arranged in each through hole I, a moisture absorption area and a drying area are arranged on the shell, the rotating disc I rotates under the driving of the driving mechanism and drives the water absorption and ventilation plates to sequentially pass through the moisture absorption area and the drying area, and compared with the prior art, the filtering effect is good, and use is convenient.
Description
【Technical field】 [0001] The invention relates to the technical field of gas detection, in particular to the technical field of a gas filter device for gas detection. 【Background technique】 [0002] During the gas sampling process, the moisture content and dust content of the working gas have a certain impact on the service life of the pump. If there is too much moisture and dust in the sampling gas path, it will increase the wear of the pump, and it will also cause the pump to be stuck and damaged. At the same time, moisture and dust in the gas path will also easily damage various sensors in the sampling instrument and reduce the service life. In the conventional desiccant water removal method, after the desiccant absorbs water, it needs to be replaced regularly by the sampler or reused after drying the desiccant, which is inconvenient to use. Therefore, there is a need for a gas filtering device for gas detection with good filtering effect and easy to use. 【Content of ...
