The utility model discloses an air bores gas - solid separator device, the grounding case comprises a case body, the air inlet pipeline, the gas discharge tube way, ball valve and a plurality of baffle, the air inlet pipeline intercommunication sets up the one side at the box, box upper portion is equipped with the roof lid, the lower part is equipped with bottom of the case board, the roof is covered and is equipped with the gas discharge tube way, this roof is covered and still is equipped with humidity transducer and pressure sensor, bottom of the case board bottom intercommunication is equipped with the ball valve, a plurality of baffle sets up downwards in the mutual slope in turn in the inside both sides of box, and the air inlet pipeline setting is in the below of the baffle of bottommost. The utility model discloses an air bores gas - solid separator device has a plurality of baffles in box the inside design, gaseous cutting carring dust entering back, because the effect of baffle leads to the gas flow rate to reduce, the bottom of the case is dropped to the detritus dust gravitate that carries, and arrange to blowdown combustion cell on the gaseous gas discharge tube way of following, opens the bottom ball valve when getting the detritus, takes out the detritus, has realized the gas -solid separation with the mechanical separation principle.
