Abstract
The utility model discloses a boiler lime -ash cooling arrangement's dust collector belongs to boiler cooling dust removal technical field. Including the conveyer belt that is used for carrying the lime -ash, the top of conveyer belt is provided with cooling sediment unloading pipe and covers the baffle box in cooling sediment unloading pipe department, the top of baffle box is connected with the pipe that removes dust, the dust removal union coupling has the boiler flue, install the negative pressure pipe on the boiler flue. The utility model discloses simple structure, convenient to use can solve the raise dust problem of the cold sediment in -process of boiler, improves the inside environment of mill, reduces the expense and the management of environment clearance.
Description
Technical field
The utility model relates to a kind of dust arrester of boiler ash cooling device, belongs to boiler cooling and dedusting technical field.
Background technology
In power industry, the improvement of boiler airborne dust is a great problem all the time, because the characteristic of coal, ash causes boiler plant production scene dust pollution serious.In boiler desmutting and deslagging system, after boiler slag removal is cooled by slag cooler, enter defeated slag crust band deflector chute by slag cooler discharging opening, then be delivered to ash residue storehouse by defeated slag crust band.At deflector chute place, the lime-ash gravity flow out of reason slag cooler enters deflector chute, causes deflector chute place flue dust serious.
Utility model content
For solving the problem, the utility model provides a kind of structure simple, the dust arrester of boiler ash cooling device easy to use.
The technical scheme that the utility model adopts for its problem of solution is:
A kind of dust arrester of boiler ash cooling device, comprise the conveyer belt for ash-slag delivery, the top of described conveyer belt is provided with cooling slag tremie pipe and covers the deflector chute at cooling slag tremie pipe place, the top of described deflector chute is connected with dust removing tube, described dust removing tube is connected with boiler flue, and described boiler flue is provided with negative tube.
Preferably, described dust removing tube has two, lays respectively at the both sides of cooling slag tremie pipe.
Preferably, the top of described conveyer belt, the below that is positioned at cooling slag tremie pipe are provided with buffer roll.
The beneficial effects of the utility model are: structure is simple, easy to use, can solve the airborne dust problem in boiler slag-cooling process, improve inside plants environment, reduce expense and the management of environment cleaning.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
In figure: 1, conveyer belt; 2, slag tremie pipe is cooled; 3, deflector chute; 4, dust removing tube; 5, boiler flue; 6, negative tube; 7, buffer roll.
Detailed description of the invention
The dust arrester of a kind of boiler ash cooling device as shown in Figure 1, comprise the conveyer belt 1 for ash-slag delivery, the top of described conveyer belt 1 is provided with cooling slag tremie pipe 2 and covers the deflector chute 3 at cooling slag tremie pipe 2 place, described deflector chute 3 is substantially in lid, be connected with dust removing tube 4 above it, it is inner that cooling slag tremie pipe 2 inserts deflector chute 3.Described dust removing tube 4 is connected with boiler flue 5, and described boiler flue 5 is provided with negative tube 6.Utilize the negative pressure of boiler back end ductwork, before the airborne dust at deflector chute 3 place is collected deduster, then processed by electrostatic precipitator or sack cleaner.
Due to cooling slag fall time, can kick up to both sides, in order to more fully siphon away dust, described dust removing tube 4 has two, lays respectively at the both sides of cooling slag tremie pipe 2.
The top of described conveyer belt 1, the below being positioned at cooling slag tremie pipe 2 are provided with buffer roll 7, to alleviate the impulsive force to conveyer belt 1 when cooling slag falls.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and utility model design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
Claims (3)
