The specific embodiment
Below in conjunction with accompanying drawing deduster is done further description: like Fig. 1, shown in 2; The offline model low pressure pulse bag filter is by air intake flue collector 1, blast pipe 2, end bucket 3, cloth bag chamber 4, air-purifying chamber 5, by-pass flue 6, smoke outlet flue 7, upper cover plate 8, casing 9, advance mouth flap valve 10, blast pipe flap valve 11, current-equalizing system 12, filtration system 13, injection system 14, by-pass flue flap valve 15, form.It is characterized in that: casing 9 struggled against for 3 airtight connections the end of with; End bucket 3 goes out to be connected current-equalizing system 12 with casing 9 transition; Upper cover plate 8 is fixedly connected on casing 9 tops, and casing 9 tops one side is an air-purifying chamber 5, and air-purifying chamber 5 belows are connected with cloth bag chamber 4 through filtration system 13 injection systems 14; In the cloth bag chamber 4 with air-purifying chamber 5 get a measuring point respectively; Pressure difference transmitter is arranged between cloth-bag type 4 and the air-purifying chamber 5, and air-purifying chamber 5 is connected with smoke outlet flue 7, has on the end bucket 3 and measures level meter (two level meter), electric heater, the air bubble of depositing the ash height; Air intake flue collector 1 is horizontal in casing 9 one sides; In import department's flue of air intake flue collector 1, connect to advance mouth flap valve 10, the thermocouple of measuring flue-gas temperature is arranged on the sidewall of air intake flue collector 1, air intake flue collector 1 lower end is communicated with end bucket 3 through blast pipe 2; Connect blast pipe flap valve 11 in the blast pipe place pipe; Air intake flue collector 1 upper end connects by-pass flue 6, connects by-pass flue flap valve 15 in by-pass flue 6 flues, and by-pass flue 6 other ends are connected with smoke outlet flue 7; Described current-equalizing system 12 is arranged for the angle steel bilayer of Q235 material; Advance mouth flap valve 10, blast pipe flap valve 11, by-pass flue flap valve 15 through the control of PLC control system.
When sack cleaner normally moved: flue gas (subsidiary dust) was by air intake flue collector 1 process blast pipe 2; Through bucket 3 at the bottom of 11 arrival of blast pipe flap valve; Get into cloth bag chambers 4 through current-equalizing system 12 and get into the clean entering air-purifying chamber 5 of filtration system 13, big dust particle gets into end bucket 3, and the pure qi (oxygen) of air-purifying chamber 5 is discharged through smoke outlet flue 7; The dust of air-purifying chamber 5 gets into end bucket 3, and bucket 3 passes through the transport discharge to impurity the end of at.
During abnormal running: flue gas is by by-pass flue flap valve 15 → by-pass flue 6 → smoke outlet flue 7
When deduster normally moves; By-pass flue flap valve 15 cuts out; Flue gas gets into air intake flue collector 1, tells corresponding blast pipe 2 according to the end 3 quantity differences that struggle against, and flue gas is gone into each cloth bag chamber by equal five equilibriums; The blast pipe flap valve 11 of this chamber of (outputing signal to PLC through pressure difference transmitter) PLC control cuts out when the cloth bag of one of them chamber reaches deashing and requires, and injection system 14 begins to jet.
The deduster design advantage: flue gas is through just contacting with cloth bag after air intake flue collector 1, blast pipe 2, end bucket 3, the current-equalizing system 12; Flue gas is through distribute layer by layer; Can pass through every cloth bag filtration uniformly, make cloth bag can not cause damage because of the uneven overload of smoke distribution.Flue gas is struggled against the end of by and contacts the surface of cloth bag from bottom to top, filters fully.Other sack cleaner flue gases directly get into cloth bag chamber and cloth bag contacts side surfaces, filter insufficient and easy damaged cloth bag.
The by-pass flue design advantage: advance to be equipped with on the mouth sidewall thermocouple (measurement flue-gas temperature) at deduster, carry signal to control system to PLC through the thermocouple measurement data, PLC controls into mouth flap valve 10, by-pass flue flap valve 15.When flue-gas temperature just often, PLC controls into mouth flap valve 10 and opens, by-pass flue flap valve 15 cuts out simultaneously, deduster gets into normal automatically operation; When flue-gas temperature was lower than or surpass the cloth bag rated temperature, PLC controlled into mouth flap valve 10 and closes, and by-pass flue flap valve 15 is opened simultaneously, and the deduster flue gas is directly discharged through by-pass flue without the cloth bag filtration, the protection filter bag.
Soot cleaning system, injection system design advantage: when one of them chamber laying dust of deduster reaches winding-up when requiring; Carry signal to give PLC by pressure difference transmitter; The blast pipe flap valve 11 of this chamber of PLC control cuts out; Make this chamber form a confined space (ash-removal effect is good), injection system begins the bag of whenever arranging is jetted successively simultaneously.When the cloth bag of this chamber all through after the winding-up once, PLC control injection system stops, and opens through airduct flap valve 11, makes this chamber get into the filtration state again.
The upper cover design advantage: some large-scale sack cleaner is arranged on outdoor, and for preventing that sleet from getting into deduster cloth bag is caused damage, upper cover design becomes ridge-roof type, and both sides are designed with tank, make things convenient for rainwater to discharge smoothly.
