Background technology
Along with the continuous increase of China's raw coal selective ratio, especially take washing as main, wash rear fine cleaned coal and need processed generation more.Fine cleaned coal is pulverous cleaned coal, and cleaned coal is exactly the coal washing of raw coal process, removes spoil in coal, is cleaned coal.2012,20.5 hundred million tons of the selected amounts of China's raw coal, selective ratio 56%, according to < < energy development " 12 planning " > >, 2015, China's raw coal selective ratio reached more than 65%.After raw coal enters to wash, when washing rear quantity of cleaned coal raising, also produce a large amount of high-moisture fine cleaned coals, or even fine cleaned coal muddy water.The fine cleaned coal product of these high-moistures must pass through processed, otherwise can cause serious environmental pollution.Fine cleaned coal reaches that again to utilize most important requirement be exactly that moisture reaches requirement, at present, background technology employing fine cleaned coal drying equipment (such as: roller drier etc.) fine cleaned coal is dried to processing, but fine cleaned coal produces a large amount of hot flue gases after drying, its dustiness is large, seriously polluted, be to hinder the dry key link of fine cleaned coal, how process the pollution problem of fine cleaned coal dried dust, become the dry field of fine cleaned coal technical problem urgently to be resolved hurrily.
Utility model content
The utility model provides a kind of fine cleaned coal drying system dust treatment plant, and simple in structure, Operation and maintenance are convenient, service time is long, reclaim hot waste gas recycling, solve the problems referred to above that background technology exists.
The technical solution of the utility model is:
A kind of fine cleaned coal drying system dust treatment plant, comprise roller drier, removal device, cyclone dust collectors, conveying worm, material envelope pump, the blower fan of delivering coal, atomizing fan, coal-powder boiler and coal-powder boiler burner, the material outlet of roller drier arranges removal device, the outlet of removal device top connects cyclone dust collectors, the dust outlet of cyclone dust collectors below connects conveying worm, conveying worm coupling has material envelope pump, material envelope pump connects coal-powder boiler burner by transport pipeline, and pipeline is provided with deliver coal blower fan and atomizing fan; Coal-powder boiler is arranged on coal-powder boiler with burner, and the exhanst gas outlet of coal-powder boiler connects the dry-heat air import of roller drier.
Described conveying worm is also provided with electric control valve, and removal device below is provided with discharging transporting equipment, and electric control valve connects discharging transporting equipment.
Described coal-powder boiler below is provided with slag transporting equipment.
The exhanst gas outlet of described cyclone dust collectors top is provided with air-introduced machine, is connected with follow-up cleaner.
It is the fine cleaned coal drying equipment system that coal-powder boiler, dust are dried dust that the utility model is applicable to heating system.The dust reclaiming can meet coal-powder boiler burning, provides hot flue gas to supply with drying system and uses.Operation principle is as follows: the dust of fine cleaned coal drying system is through cyclone dust collectors depositing dust, by series of steps such as coal powder conveyer, pipeline reprinting, motorized adjustment valve regulation coal dust amounts, by the blower fan of delivering coal, send into coal-powder boiler burner, more fully burn after atomizing fan atomization; The dust of not removing through cyclone dust collectors enters follow-up cleaner after dust delivering tube route air-introduced machine is extracted out, and after filtering, the steam of meet the requirement of environmental protection enters atmosphere.If the dust of falling through cyclone dust collectors exceeds coal-powder boiler use amount, can enter coal-powder boiler coal supply pipeline by a bifurcated pipeline part, the dust having more in addition part can drying system discharging equipment, transports together with fine cleaned coal after dry.
The beneficial effects of the utility model are: the hot dust recycling that the utility model produces roller drier, be directly used in coal-powder boiler burning and produce hot blast, feed roller drying machine uses as dry-heat air, form a benign cycle, both saved the expense of background technology outsourcing coal dust, energy-conserving and environment-protective again, simple in structure, Operation and maintenance are convenient, service time is long, reclaim hot waste gas recycling, effectively solved dry after the problem of fine cleaned coal dust pollution.
