ABSTRACT:
The present invention relates to a gas filtering-buffering device, which comprises at least one gas filtering unit; a gas inlet, the gas to be processed flows into the at least one gas filtering unit from the gas inlet; and a gas outlet, the gas processed by the at least one gas filtering unit is discharged out of the at least one gas filtering unit via the gas outlet, wherein the at least one gas filtering unit comprising: a gas buffering cavity for performing buffering function for the gas, and a gas filtering part for performing filtering function for the gas. In the present invention, it is not only provided with a gas filtering part which is able to filter the moisture and organic substance in the gas, but also provided with a gas buffering cavity, which integrate the filtering and buffering functions together. The buffering cavity may expand the capacity and stabilize the pressure of the gas, and balance the concentration, pressure and flow rate of the gas, it is advantageous to reduce the on-way pressure lost and partially pressure lost, decrease fluctuation of the flow current and the pressure thus, the detecting performance of the detector is improved.
