Description
Technical field
The utility model belongs to power station environmental technology field, is specifically related to a kind of power station dust removing appts. of coal conveying system, and it can effectively be applied in the elimination of dust contamination project of power station.
Background technology
The dust harzard such as thermal powerplant, central heating stations, colliery is more greatly a common problem, and in coal handling system design, general pulsed jet cloth filter and the multi-pipe impact dust collector of using is as dust removal installation.Thermoelectric power station uses spoil in a large number, coal handling plant dust severe overweight, causes each belt cleaner work load of coal handling system large, there is dust pelletizing system plant maintenance complexity, fault is many, the problems such as dust pollution is serious, have a strong impact on the work efficiency of coal handling system and the healthy of workman.
Summary of the invention
The utility model provides a kind of power station dust removing appts. of coal conveying system, solves the problems such as the energy consumption existed in the elimination of dust contamination of power station is high, repair and maintenance work capacity large, material consumption expense is high.
The technical solution of the utility model is:
A kind of power station dust removing appts. of coal conveying system, comprise defeated coal support, be arranged at the coal conveyer belt on defeated coal support and be arranged at the arc deflector chute above coal conveyer belt, arc deflector chute is disposed with ash bucket, rapping device for reducing dust, coal spout, overlay film flat bag filter, shower nozzle and double-deck check apron along defeated coal direction; Edge seal is provided with, at ash bucket be provided with two W type telescopic rubber sealing band between rapping device for reducing dust and coal conveyer belt between described arc deflector chute and coal conveyer belt.
Described ash bucket and rapping device for reducing dust are arranged at the front end of arc deflector chute, and described double-deck check apron is arranged at the end of deflector chute.
Described edge seal is fixed on the side plate of arc deflector chute both sides, and it comprises the interpolation sealing band of ground floor and the sealing band that turns up of the second layer.
The beneficial effects of the utility model:
1, the sealed environment created of the utility model, make that the induction that produces (between coal spout and deflector chute) between equipment and material in material conveying process is distinguished and admirable, air-shock wave is distinguished and admirable and distinguished and admirable the producing in dirt region equipment of belt feeder traction creates tiny structure, reaches the object of negative pressure dust control.
2, the utility model adopts soft seal application engineering, and the moving law according to different equipment and equipment is designed: the edge seal arranged between arc deflector chute and coal conveyer belt; The double-deck check apron of deflector chute end; The two W type telescopic rubber sealing bands arranged between rapping device for reducing dust and coal conveyer belt; Carry out actv. edge seal between equipment gap, reach stifled dirt, the dust-proof effect with negative pressure dust control.
Accompanying drawing explanation
Fig. 1 is integral structure schematic diagram of the present utility model.
In figure, the defeated coal support of 1-, 2-coal conveyer belt, the arc deflector chute of 3-, 4-ash bucket, 5-rapping device for reducing dust, 6-coal spout, 7-overlay film flat bag filter, 8-shower nozzle, the double-deck check apron of 9-, 10-edge seal.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further detailed, a kind of power station dust removing appts. of coal conveying system as shown in Figure 1, comprise defeated coal support 1, be arranged at the coal conveyer belt 2 of on defeated coal support 1 and be arranged at the arc deflector chute 3 above coal conveyer belt 2, arc deflector chute 3 is disposed with ash bucket 4, rapping device for reducing dust 5, coal spout 6, overlay film flat bag filter 7, shower nozzle 8 and double-deck check apron 9 along defeated coal direction; Edge seal 10 is provided with, at ash bucket 4 be provided with two W type telescopic rubber sealing band between rapping device for reducing dust 5 and coal conveyer belt 2 between arc deflector chute 3 and coal conveyer belt 2; Edge seal 10 and two W type telescopic rubber sealing band carry out actv. edge seal between equipment gap, finally reach stifled dirt, the dust-proof effect with negative pressure dust control.Ash bucket 4 and rapping device for reducing dust 5 are arranged at the front end of arc deflector chute 3, and double-deck check apron 9 is arranged at the end of deflector chute 3.
Edge seal 10 is fixed on the side plate of arc deflector chute 3 both sides, and edge seal 10 is " dovetail type " interpolation outer rotating edge rubber seal tape, and it comprises the interpolation sealing band of ground floor and the sealing band that turns up of the second layer.
Overlay film flat bag filter 7 of the present utility model adopts the multiple film flat bag filter of LFD series, dusty gas in arc deflector chute 3 is sucked filter chamber by bottom ventilation inlet by it, more broadcast on filter bag, dust, by filter bag detention, purifies air and to discharge from exhaust outlet through fan house through bag wall.It is asynchronous to bat vibration that automatic sensing detection rapping apparatus makes odd even two produce between the flat cloth bag of group insertion greatly, when patting cloth cover, timesharing is closed, anticyclonic pressure is generated between cloth cover when being harmonious, infrabar is generated between cloth cover during separation, each cloth cover two side draught head constitutes blowback air pulse, make laying dust more thoroughly peel off cloth cover, reach the object of optimum filtration deashing.
Overlay film flat bag filter 7 is arranged on arc deflector chute 3 upper end of double containment, after being peeled off by the dust be adsorbed on cloth bag, directly falls on coal conveyer belt, does not produce second time dust pollution by Automatic-falling and beating.The blower fan of this dusting equipment and the work of bent axle rapping are carried out by PLC programming control and with coal conveyer belts and are interlocked, and whole work runs and all carries out automation.
Content of the present utility model is not limited to cited by embodiment, and the conversion of those of ordinary skill in the art by reading the utility model specification sheets to any equivalence that technical solutions of the utility model are taked, is claim of the present utility model and contains.
