Description
Technical field
The utility model relates in coal-fired power station boiler flying dust collection process a kind of blockage-eliminating device, particularly a kind of dust conveying system blockage-eliminating device after there is stifled ash.
Background technology
Current China coal-fired power station boiler flying dust generally adopts the mode of malleation thick and thin phase burner to collect, quality because of Boiler Ash differs or equipment deficiency fault, easily cause the stifled ash of pneumatic transport equipment pipeline, system is caused not run, existing fly ash carry equipment pipe blockage-eliminating device mostly realizes automatically controlling in conjunction with PLC, although automatically tackling blockage during flying dust blocking can be realized, but cost is higher, and coal-fired power station boiler operating mode is severe, be unsuitable for the work of electronic machine, automatically controlled blockage-eliminating device needs to safeguard frequently, in addition, existing fly ash carry equipment pipe unimpeded measure also comprises artificial unloading's equipment and pipeline unimpeded, waste time and energy, considerably increase the production and operation cost of coal fired power plant.
Utility model content
The purpose of this utility model is to provide a kind of dust conveying system blockage-eliminating device, the deficiency of automatically controlled blockage-eliminating device can be overcome, do not need frequent maintenance, simple and feasible, can effectively utilize that dust collector ash hopper is inner carries out unimpeded for negative pressure, when ash conduit generation plugging, open unimpeded pipe bottom valve, dust collector ash hopper internal negative pressure is utilized to bleed, because dust collector ash hopper top is inserted on unimpeded pipe top, and higher than the high charge level meter on dust collector ash hopper, thus ensure that the outlet of unimpeded pipe can not be covered by dust stratification in dust collector ash hopper, can to be loosened the grey bolt gathered in ash conduit by negative pressure ventilation like this, realize unimpeded function.
The technical solution of the utility model is as follows: a kind of dust conveying system blockage-eliminating device, comprise transmission pump, dust collector ash hopper and high charge level meter, ash conduit after transmission pump is connected with unimpeded pipe, unimpeded pipe bottom is connected with valve, unimpeded pipe end is connected with ash conduit pipe top, dust collector ash hopper top is inserted on unimpeded pipe top, and higher than the high charge level meter on dust collector ash hopper, ensures that the outlet of unimpeded pipe can not be covered by the dust stratification in dust collector ash hopper.
In aforesaid dust conveying system blockage-eliminating device, described unimpeded pipe upper angled section and horizontal plane angle are not less than 60 degree, the angle of unimpeded pipe top section crossing with dust collector ash hopper and vertical direction is not more than 30 degree, make the ash entering unimpeded pipe from ash conduit to fall back ash conduit under gravity, unimpeded blockage can not be caused.
In aforesaid dust conveying system blockage-eliminating device, the caliber of described unimpeded pipe is determined according to the specification of ash conduit, the valve that unimpeded pipe bottom connects is manually-operated gate or operated pneumatic valve, when ash conduit generation plugging, open unimpeded pipe bottom operated pneumatic valve or manually-operated gate, utilize dust collector ash hopper internal negative pressure to bleed, the stifled ash in loose ash conduit, coordinate defeated ash to supply gas simultaneously, realize unimpeded function.
Compared with prior art, the utility model structure is simple, when blocking occurs ash conduit, opens valve and effectively can remove stifled ash, coordinate defeated ash to supply gas simultaneously, realize unimpeded function; Can not alleviate can multiple switching operated pneumatic valve or manually-operated gate attempt as plugging; Because unimpeded pipe upper angled section and horizontal plane angle are not less than 60 degree, the ash entering unimpeded pipe from ash conduit can fall back ash conduit under gravity, can not cause unimpeded blockage; In addition because dust collector ash hopper top is inserted on unimpeded pipe top, and higher than the high charge level meter on dust collector ash hopper, thus ensure that the outlet of unimpeded pipe can not be covered by dust stratification in dust collector ash hopper, can be loosened unimpeded pipe by negative pressure ventilation like this, realize unimpeded function; In addition, the utility model structure is simple, does not need frequent maintenance, is easy to manufacture, and low cost of manufacture, can effectively reduce production and operation cost.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Being labeled as in accompanying drawing: 1-transmission pump, 2-ash conduit, 3-unimpeded pipe, 4-valve, 5-dust collector ash hopper, 6-high charge level meter.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is further described.
Embodiment 1 of the present utility model: as shown in Figure 1, a kind of dust conveying system blockage-eliminating device, comprise transmission pump 1, dust collector ash hopper 5 and high charge level meter 6, ash conduit 2 after transmission pump 1 is connected with unimpeded pipe 3, unimpeded pipe 3 bottom is connected with valve 4, unimpeded pipe 3 end is connected with ash conduit 2 pipe top, and dust collector ash hopper 5 top is inserted on unimpeded pipe 3 top, and higher than the high charge level meter 6 on dust collector ash hopper 5; Unimpeded pipe 3 upper angled section and horizontal plane angle are 60 degree, and unimpeded pipe 3 top is 30 degree with the crossing section of dust collector ash hopper 5 and the angle of vertical direction; The caliber of described unimpeded pipe 3 is determined according to the specification of ash conduit 2, and the valve 4 that unimpeded pipe 3 bottom connects is manually-operated gate.
Embodiment 2 of the present utility model: as shown in Figure 1, a kind of dust conveying system blockage-eliminating device, comprise transmission pump 1, dust collector ash hopper 5 and high charge level meter 6, ash conduit 2 after transmission pump 1 is connected with unimpeded pipe 3, unimpeded pipe 3 bottom is connected with valve 4, unimpeded pipe 3 end is connected with ash conduit 2 pipe top, and dust collector ash hopper 5 top is inserted on unimpeded pipe 3 top, and higher than the high charge level meter 6 on dust collector ash hopper 5; Unimpeded pipe 3 upper angled section and horizontal plane angle are 75 degree, and the angle of unimpeded pipe 3 top section crossing with dust collector ash hopper 5 and vertical direction is 15 degree; The caliber of described unimpeded pipe 3 is determined according to the specification of ash conduit 2, and the valve 4 that unimpeded pipe 3 bottom connects is operated pneumatic valve.
Unimpeded principle of the present utility model: because dirt pocket ash bucket 5 inside is negative pressure, when there is plugging in ash conduit 2, open the valve 4 of unimpeded pipe 3 bottom after transmission pump 1, utilize the negative pressure ventilation of dust collector ash hopper 5 inside, stifled ash in loose ash conduit 2, coordinate defeated ash to supply gas simultaneously, realize unimpeded function; Can not alleviate can attempt by multiple switching valve 4 as unimpeded pipe; Because unimpeded pipe 3 upper angled section and horizontal plane angle are not less than 60 degree, the ash entering unimpeded pipe 3 from ash conduit can fall back ash conduit 2 under gravity, and unimpeded pipe 3 can not be caused to block; In addition because dust collector ash hopper 5 top is inserted on unimpeded pipe 3 top, and higher than the high charge level meter 6 on dust collector ash hopper 5, thus ensure that the outlet of unimpeded pipe 3 can not be covered by dust stratification in dust collector ash hopper 5, can be loosened ash conduit 2 by negative pressure ventilation like this, realize unimpeded function.
