Description
Technical field
The utility model relates to power plant production field, is specifically related to a kind of power plant coal dust process regenerative apparatus.
Background technology
Thermal powerplant is when carrying coal cinder or coal dust, and coal conveyer belt layer is the main place of mass transport, one of dirt source point that Ye Shi coal-burning power plant is main.Pollution caused by coal dust is mainly at belt receiving opening, discharge port, transfer point and when adopting belt plow or scraper-type discharger that the coal on belt is discharged into the blanking port of coal bunker, because drop is larger, a large amount of dust can be produced when belt feeder is separated with coal, at the blanking port place of coal bunker, along with coal position in storehouse raises, dusty gas is discharged and diffusion from coal dropping port, causes pollution in wide area.Even, because the temperature of damping coal is higher, coal dust splashes to it operating personal, can cause the safety misadventures such as scald.
Summary of the invention
The purpose of this utility model is to provide a kind of power plant coal dust process regenerative apparatus, has effectively to collect coal dust, reduce the function kicked up of coal dust.
The technical matters that the utility model solves can realize by the following technical solutions: a kind of power plant coal dust process regenerative apparatus, described coal dust process regenerative apparatus is arranged on above coal conveyer belt, comprise holder device, dust-reduction device and regenerative apparatus, described dust-reduction device is connected with holder device, regenerative apparatus is connected with dust-reduction device, described dust-reduction device comprises dust removal by ventilation mechanism and water spray dedusting mechanism, dust removal by ventilation mechanism is by main pipeline, several branch pipe(tube)s, blower fan, seal closure and exhaust hood composition, branch pipe(tube) is connected with main pipeline, exhaust hood is connected with a shroud, be connected with coal conveyer belt bottom seal closure, seal closure top is connected with exhaust hood, blower fan is arranged in main pipeline.
Preferably, described water spray dedusting mechanism is provided with several sprinklers, and sprinkler is connected on holder device by peg.
Preferably, described regenerative apparatus is provided with dust exhaustor, and main pipeline fan installation place is other is provided with joint, and dust exhaustor is connected with joint.
Preferably, described holder device is made up of strut bar and crossbeam, and crossbeam is connected with strut bar.
Preferably, described dust exhaustor adopts fiber bag precipitator.
Beneficial effect: collection, the process of this power plant coal dust process regenerative apparatus by adopting centralized ventilating and purifying air system to carry out belt layer dust.The technical program controls the diffusion of coal dust by adopting seal closure at belt transport point place, and owing to there is coal plough in coal spout place, in order to overhaul conveniently, hood is adopted to carry out the collection of dust, region between transfer point and coal spout and each branch pipe(tube), when belt normally runs, large vibrations can not be produced, so we adopt the method for water spray dust to suppress airborne dust in these regions, can reach preferably except coal dust effect, the coal dust produced in course of conveying can not spill in air, decreases the waste of coal resources; Described dust exhaustor adopts conventional fiber bag precipitator, except under dust through rapping apparatus regularly by flue-dust retainer, ash-unloading tube discharge or directly drain on belt or in coal bunker, the efficiency of dust collection of this dust exhaustor is also higher, can reach more than 99%, and the coal dust of dedusting gained can recycle.
