Description
The utility model relates to a kind of positive positive-pressure cloth bag back suction deduster, a kind of specifically positive-pressure industrial dust source device positive-pressure cloth bag circulating flue gas back air suction deashing dust cleaner.
At present, when particularly high-temperature flue gas adopts sack cleaner for positive-pressure industrial dust source device, its purge mode can not adopt back suction wind deashing, can only use mode deashings such as mechanical vibrator, pulse jet, and the mechanical vibrator deashing is because filter bag often is subjected to the effect of horizontal or vertical mechanical force, the filter bag cracky, the workload that has increased maintenance and changed bag; Or adopt synthetic fibers such as high-temperature nylon, special teflon etc. to make filter bag, then cost is higher.
The purpose of this utility model provides a kind of positive-pressure industrial dust source device positive-pressure cloth bag circulating flue gas back air suction deashing dust cleaner.
The utility model is to realize its goal of the invention by the following technical solutions, a kind of positive positive-pressure cloth bag back suction deduster, it comprises the ash-laden gas inlet, the ash-laden gas pipeline, the smoke inlet valve, the back suction air valve, card, filter bag, the pure qi (oxygen) outlet, dust hopper, back suction airduct road, gas inlet and outlet, air blast, the deduster body, the ash-laden gas that the industrial dust source device produces enters the mouth by ash-laden gas, the ash-laden gas pipeline, the smoke inlet valve, gas inlet and outlet enters the deduster body and is discharged by the pure qi (oxygen) outlet after filter bag purifies, filter bag is fixed on the card, air blast is positioned on industrial dust source device front end, between ash-laden gas inlet and ash-laden gas pipeline, be provided with air deflector, back suction airduct road is linked to each other with air deflector.
If the dust concentration height in the ash-laden gas, the airflow stability of industrial dust source device inside requires high, is provided with the back suction blower fan between back suction airduct road and air deflector.
Be installation, operation, easy to process, reliable operation, smoke inlet valve, back suction air valve adopt reversing ball central layer valve.
Because adopt above technical scheme, the utility model has more ideally been realized goal of the invention, realized that positive-pressure industrial dust source device with the positive-pressure cloth bag dedusting and adopt circulating flue gas back suction wind deashing, has characteristics such as simple in structure, easy to use, reliable operation.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in further detail: as can be known by accompanying drawing, it comprises ash-laden gas inlet 2 the utility model, ash-laden gas pipeline 4, the smoke inlet valve, the back suction air valve, card 6, filter bag, pure qi (oxygen) outlet 10, dust hopper 13, back suction airduct road 16, gas inlet and outlet 22, air blast 18, deduster body 8, the ash-laden gas 17 that industrial dust source device 1 produces is by ash-laden gas inlet 2, ash-laden gas pipeline 4, the smoke inlet valve, gas inlet and outlet 22 enters deduster body 8 and is discharged by pure qi (oxygen) outlet 10 after filter bag purifies, filter bag is fixed on the card 6, air blast 18 is positioned on industrial dust source device 1 front end, be provided with air deflector 19 between ash-laden gas inlet 2 and ash-laden gas pipeline 4, back suction airduct road 16 links to each other with air deflector 19; If the dust concentration height in the ash-laden gas 17, the airflow stability of industrial dust source device 1 inside requires high, is provided with back suction blower fan 20 between back suction airduct road 16 and air deflector 19; Be installation, operation, easy to process, reliable operation, smoke inlet valve, back suction air valve adopt reversing ball central layer valve 21.
Ash-laden gas 17 is under the thrust of air blast 18, enter ash-laden gas pipeline 4 by industrial dust source device 1 through ash-laden gas inlet 2, at this moment be negative pressure in the air deflector 19, back suction general mood stream 15 enters air deflector 19, converge by ash-laden gas pipeline 4 to ash-laden gas pipeline 4 and ash-laden gas 17, the smoke inlet valve, gas inlet and outlet 22 purifies through filter bag, this moment, filter bag was in bag house filtration state 11, purifying back gas 9 is discharged by pure qi (oxygen) outlet 10, when a certain filter bag needs deashing, close the smoke inlet valve, open the back suction air valve, because back suction airduct road 16 links to each other with air deflector 19 negative pressure ends, the filter bag for the treatment of deashing is in negative pressure state, make filter bag become flat, this moment, filter bag was in bag house deashing state 7, the keying of closing valve is arranged by control, filter bag expands several times flat, make filter bag inwall dust releasing, a part falls into dust hopper 13, discharge by dust-exhausting port 14, fraction enters other filter bags purified treatment again through back suction airduct road 16 with back suction general mood stream 15 after air deflector 19 and ash-laden gas 17 converge.
Reversing ball central layer valve 21 is reciprocating by the valve plate of being furnished with the ball core on the push rod, during toward a direction motion, link to each other with the import in back suction airduct road 16, during toward another direction motion, link to each other with the outlet of ash-laden gas pipeline 4, reach the purpose that control back suction general mood stream 15 and ash-laden gas 17 debouch gas inlet and outlet 22.Replace back suction air valve and smoke inlet valve by a reversing ball central layer valve 21, can reduce the deduster cost, simplify and install, reduce the control program and the maintenance of valve.
