Detailed Description
Referring to fig. 1-15, the present invention provides a technical solution: comprises a self-scraping communicating pipe 1 communicated between an exhaust port of an absorption tower 17 and an air inlet of a bag-type dust collector 18;
a scraper part driven by hot air pressure and an agitation part driven by the scraper part are arranged in the self-scraping communicating pipe 1;
the scraper part comprises two scraper plates 4 which are symmetrically arranged and can be turned over, the outer side walls of the scraper plates 4 are connected with the inner walls of the ventilation channels 10 of the self-scraping communicating pipes 1 in a sliding mode, the two scraper plates 4 are arranged on one side of an exhaust port of the absorption tower 17 and cover the ventilation channels 10 in the self-scraping communicating pipes 1, when the air pressure in the absorption tower 17 is enhanced, hot air pressure drives the two scraper plates 4 to slide towards one side of an air inlet of the bag-type dust collector 18 in a covering mode through the rotating sliding part, the rotating sliding part comprises a turning mechanism for triggering the scraper plates 4 to be turned over or covered and a reset mechanism for automatically returning to one side of the air inlet of the absorption tower 17, and the two sides of the exhaust direction of the ventilation channels 10 are respectively provided with trigger mechanisms for keeping the scraper plates 4 to be turned over and covered;
the stirring part comprises suction fan blades 20 and back blowing fan blades 21 which are rotatably arranged at the axial center position of the ventilation channel 10, the back blowing fan blades 21 and the suction fan blades 20 are respectively arranged at the front side and the back side of the wall scraping plate 4 along the exhaust direction, the suction fan blades 20 are arranged at one side of the exhaust port of the absorption tower 17, the back blowing fan blades 21 are arranged at one side of the air inlet of the bag-type dust remover 18, when the wall scraping plate 4 moves towards one side of the bag-type dust remover 18 in a covering state, the suction fan blades 20 and the back blowing fan blades 21 coaxially rotate, the suction fan blades 20 suck air flow towards the air inlet of the bag-type dust remover 18, and the back blowing fan blades 21 blow air flow towards the exhaust port of the absorption tower 17;
when the dust remover works, when the absorption tower 17 exhausts air towards the inside of the bag-type dust remover 18, the self-scraping communicating pipe 1 is wholly blocked by the scraping plate 4, hot smoke which upwards surges is blocked and flows backwards into the absorption tower 17 to be sprayed and desulfurized, meanwhile, the air pressure inside the absorption tower 17 is enhanced, the air pressure pushes the covered scraping plate 4 towards the air inlet of the bag-type dust remover 18, the outer side wall of the scraping plate 4 carries out dust scraping operation on the inner wall of the ventilation channel 10 in the pushing process, meanwhile, the scraping plate 4 drives the suction fan blades 20 and the back-blowing fan blades 21 of the stirring part to rotate in the moving process, at the moment, the suction fan blades 20 suck air towards the air inlet of the bag-type dust remover 18, the air flow in the bag-type dust remover 18 is reversely stirred, dust

opening state and return to one side of an exhaust port of the absorption tower 17 again, at the moment, the trigger mechanism at one side of the exhaust port of the absorption tower 17 covers the two scraping wall plates 4 on the exhaust port of the absorption tower 17 again through the opening and closing mechanism, so as to perform reciprocating circulation action, in the return process of the scraping wall plates 4, the stirring part is integrally reversed, the suction fan blades 20 blow air in the bag-type dust collector 18, the back blowing fan blades 21 suck air in the absorption tower 17, the speed of the flue gas passing through the self-scraping communicating pipe 1 is improved, namely, in the process of opening the inside of the ventilating channel 10 through the scraping wall plates 4, the arranged stirring part does not interfere the flue gas passing, but promotes the air flow passing efficiency, therefore, the invention blocks the ventilating channel 10 inside the self-scraping communicating pipe 1 through the two foldable scraping wall plates 4, and converts the hot-pressing scraping of the air flow into the moving thrust of the scraping wall plates 4 in a mode of higher hot air flow air pressure in the absorption tower 17, the automatic transverse movement ash scraping operation of the scraping plate part can be realized, in the ash scraping process, the set stirring part can reversely stir the flue gas in the absorption tower 17 to improve the desulfurization efficiency of the flue gas when the scraping plate part scrapes the ash, the set suction fan blade 21 can reversely pump the interior of the bag-type dust collector 18 to reduce the dust attachment rate of a dust collection bag in the bag-type dust collector 18, in the return stroke process of the stirring part, the suction fan blade 20 and the reverse blow fan blade 21 can also improve the flue gas passing efficiency, therefore, the flue gas in the ventilation channel 10 integrally passes through in the form of pulse air flow, the self-cleaning in the ventilation channel 10 is realized in the air flow passing process, the desulfurization efficiency in the absorption tower 17 and the dust collection efficiency in the bag-type dust collector 18 are reversely promoted, and the integral driving is driven by the air pressure form of hot air flow in the absorption tower 17, the damage of heat flow dust to the dust removal cloth bag in the cloth bag dust remover 18 is reduced, meanwhile, the heat energy of the smoke is utilized to the maximum extent, and the
