Description
Technical field
The present invention relates to a kind of alumina producer gas producer gas station coal handling system dedusting ash discharging system device.
Background technology
In alumina producer gas station coal handling system, dust collecting system produces a lot of coal dusts, but in the dust collecting system of in the past gas station coal handling system, often directly feed back the coal belt, enter the gas furnace system, because the coal particle size that gas station requires is 13～50mm by the dust exhaustor ash-unloading tube, and the dust size that dust collecting system is received is＜1mm, entering the next stage coal handling system not only can increase the Dust Capacity of next stage coal handling system, also can have a strong impact on the gas production rate of gas furnace, has wasted fuel.And dust collecting system is collected the production requirement that coal dust just in time satisfies thermoelectric power station.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of alumina producer gas station coal handling system dedusting ash discharging system device is provided, this device can not only significantly reduce the amount of gathering dust of coal handling system next stage, improve the gas furnace factor of created gase, and effectively utilize coal dust, saved the energy, to overcome the deficiency that prior art exists.
Technical scheme of the present invention is: defeated coal dust collection cover is set on coal conveyer belt, and defeated coal dust collection cover is connected with dust exhaustor by pipeline, and dust exhaustor is connected with the surge bunker that gathers dust, and sets gradually the device of push-pull valve, reducing raising dust in loading powder in the lower end of surge bunker; Above the surge bunker that gathers dust dust collection cover is set, dust collection cover is connected with dust exhaustor by pipeline.
On the connecting tube of defeated coal dust collection cover and dust exhaustor, volume damper is arranged.
On dust collection cover and dust exhaustor bonded assembly pipeline, volume damper is arranged.
The dust collection cover of installing on the surge bunker that gathers dust is in order that collect the reentrainment of dust of the surge bunker that gathers dust.
Push-pull valve control is installed under the surge bunker that gathers dust regularly unloads ash, effectively regulate the volume of the surge bunker that gathers dust.
The device of reducing raising dust in loading powder is installed under the surge bunker push-pull valve that gathers dust, for the minimizing dust from flying.
During work, the dust of collecting from coal conveyer belt enters dust exhaustor by volume damper, and dust exhaustor unloads ash to the surge bunker that gathers dust, and on the surge bunker that gathers dust dust collection cover is set, and the dust that the pipe that gathers dust is collected returns dust exhaustor air intake house steward.There is push-pull valve the gather dust lower end of surge bunker, and the device of reducing raising dust in loading powder is installed under push-pull valve, regularly pulls away with car again and transports the thermoelectric power station utilization to.
The present invention compared with prior art provides a kind of alumina producer gas station processing method that ash is unloaded in the coal handling system dedusting, in treating process, not only significantly reduced the amount of gathering dust of coal handling system next stage, improve the gas furnace factor of created gase, and effectively utilized coal dust, saved the energy.
