Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-2, an explosion-proof bag collector, including dust removal box 1, the inside of dust removal box 1 is provided with filter bag 8, the top of filter bag 8 is provided with pulse dust collector 7, the bottom of dust removal box 1 is provided with grey hopper 2, the both sides of dust removal box 1 are provided with air-supply line 3 and play tuber pipe 4 respectively, still be provided with elimination room 5 between air-supply line 3 and the dust removal box 1, be provided with spark eliminator 6 in the elimination room 5, the inside top of dust removal box 1 is provided with multiunit face downward protection shower nozzle 9, the outside of dust removal box 1 is provided with protection device, protection device includes equipment box 10, the inside of equipment box 10 is provided with liquid nitrogen storage bottle 11, liquid nitrogen storage bottle 11 is connected with protection shower nozzle 9 through communicating pipe 15, still be provided with solenoid valve 12 on the communicating pipe 15, air-vent valve 13 and manometer 14.
Aiming at the potential safety hazard of fire and explosion existing in the suction filtration and ash removal processes of the existing dust remover, the scheme is provided with an elimination chamber 5 at the connection position of the air inlet pipe 3 and the dust removal box body 1, a spark eliminator 6 is arranged in the elimination chamber 5, and the spark eliminator 6 can eliminate sparks in the sucked air, so that the spark is prevented from igniting dust or causing explosion; in the ash removal process, the protection device can spray low-temperature nitrogen into the dust removal box body 1 through the liquid nitrogen storage bottle 11, the communicating pipe 15 and the protection spray nozzle 9, the sprayed nitrogen can effectively reduce the internal temperature of the dust removal box, and meanwhile, the oxygen content can also be reduced, so that the probability of dust explosion in the ash removal process is greatly reduced.
