| description | The utility model discloses a drying and filtering device for gas chromatography pretreatment, which is characterized by comprising a gas-water separator (1), and a pressure reducing valve (2), a condenser (3) and a drying filter (4) which are sequentially connected with the gas-water separator (1), sample gas enters the gas-water separator (1) from the sampling port (6) through the sampling valve (5) for first moisture removal; and the condenser (3) is positioned behind the pressure reducing valve (2). A three-stage dewatering, filtering and pressure reducing method is adopted, the sample gas dewatering and drying functions are achieved, compared with the prior art, the mounting position of the pressure reducing valve is improved, the drying filter is added, the molecular sieve is filled, and the remarkable technical effect of drying and filtering is achieved.
