Embodiment 1
[0034] figure 1 It is an underground ventilation and dust removal safety system for coal mines according to the present invention. The system includes two bellows, two parallel bellows, the first bellows (1) and the second bellows (2), which are respectively arranged inside the mine. On both sides, the bellows are coated with self-luminous paint, and the two bellows extend from the outside of the mine to the bottom of the well;
[0035] The first bellows is connected with the blast device (3) outside the mine, and the blast device blows the purified air into the first bellows, and several tees (4) are arranged at intervals on the first bellows. ), the branch pipe of the three-way pipe perpendicular to the bellows is connected with an exhaust device (5), which blows the air in the bellows into the mine;
[0036] The second corrugated pipe is arranged in parallel with the first corrugated pipe, and several tees (4) are arranged at the place corresponding to the first corrugated...
Embodiment 2
[0039] Such as figure 2 As shown, it is the integrated filter and dust removal device of the present invention in the daily working state, the integrated filter and dust removal device for coal mine safety of the present invention, and the integrated filter and dust removal device includes a fan, a housing, an adsorption filter part, a water vapor dust removal part, a bag dust removal part and dust Entrance;
[0040] After the dust inlet, the water vapor dust removal parts, bag dust removal parts, fan and adsorption filter parts are arranged in sequence, and the housing is located outside the entire integrated filter dust removal device;
[0041] The water vapor dedusting part is used for preliminary water vapor dedusting of the dust collected from the dust inlet into the integrated filter dedusting device; the bag dust removal part is used for bag dedusting of the dust particles that still exist in the gas after being treated by the water vapor dedusting part ;
