Abstract
The utility model discloses a production device for fly ash flotation carbon, which comprises a screen separation module, a stirring module, a flotation module, a dehydration module and a conveying mechanism, wherein, the screen separation module and the stirring module can filter the granularity of flay ash; the flotation module and the dehydration module can separate fine coal and tail ash; and the conveying mechanism organically connects the modules into a whole in sequence. The utility model has simple structure and can achieve the purpose for sufficiently utilizing the resources.
Description
Technical field
The utility model relates to a kind of flyash flotation charcoal process units.
Background technology
Along with the develop rapidly of industrial economy, and people are to the continuous enhancing of environmental protection consciousness, and people very pay attention to the influence to environment of solid emission that coal-fired station produces.In these emissions, flyash accounts for major part.Flyash is the product after the powdery burning in the coal-burning boiler combustion process.All produce a large amount of flyash in the coal-burning power plant.How these flyash are used for landfill or brickmaking at present, fail effectively to utilize unburnt surplus charcoal.As fly ash charcoal-removing is handled, make smart charcoal and ash content of coal can make fuel or raw material usefulness again from, then smart charcoal, then concrete mixing plant and the cement plants of being used for of tail ash by extensively good and employing more.The present domestic two kinds of fly ash charcoal-removing methods that have: the high resultant effect of firing method energy consumption is not good, and electrical concentration requires limitation bigger to grey source, and fails to put into production in a large number.
Summary of the invention
The utility model purpose is to overcome original technical deficiency part, and a kind of efficient, high-quality, the energy-conservation process units that utilizes flyash are provided.
Goal of the invention of the present utility model is achieved in that a kind of flyash flotation charcoal process units, it is characterized in that: described flyash flotation charcoal process units comprises the screening module that can screen the flyash granularity, stirs module, can cleaned coal and tail ash content from flotation module, dehydration module and the conveying mechanism that becomes integral body with upper module organic connections successively.
Described screening module comprises the screen drum that is connected with conveying mechanism.
Described stirring module comprises agitator and the chemicals dosing plant that is connected with the flotation module, and conveying mechanism is connected with the stirring module.
Be provided with delivery pump between described stirring module and the flotation module.
Described flotation module comprises flotation column and bubble generator.
Be provided with enrichment facility between described flotation module and the dehydration module.
Described dehydration module is the dewatering machine device.
The utility model takes off the charcoal technology to the flyash flotation of prior art to be improved, the flotation of flyash is divided into four module in process units finish, flyash enters screening module, stirring module, flotation module and dehydration module in turn by conveying mechanism, and cleaned coal and tail ash are separated in flyash.Flyash flotation charcoal process units of the present utility model, simple in structure, reach the purpose that resource makes full use of.
Description of drawings
Accompanying drawing 1 is the principle schematic of the utility model most preferred embodiment.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Shown in 1, flyash flotation charcoal process units of the present utility model comprises screening module, stirring module, flotation module and dehydration module 8 with reference to the accompanying drawings.The screening module can be screened the granularity of the flyash that enters by conveying mechanism 1, and the screening module mainly comprises screen drum 2, and screen drum 2 is communicated with conveying mechanism 1, and this screen drum 2 can be rotary screen.The screening module can be sifted out impurity in the coal ash and particle, and 1 of conveying mechanism is connected with the stirring module.Stir module and comprise agitator 3 and chemicals dosing plant 4, chemicals dosing plant 4 is connected with agitator 3, and wherein agitator 3 is connected with the screening module.Be provided with delivery pump 5 between flotation module and the stirring module.The flotation module comprises flotation column 6 and bubble generator 7, and this flotation column 6 and bubble generator 7 interact and overflow bubble, thereby separate to deviate from cleaned coal and tail ash.Be provided with enrichment facility 9 between flotation module and the dehydration module, dehydration module 8 is the dewatering machine device, also is provided with the tube 81 that degass that is connected with enrichment facility 9 in the dehydration module 8.
During work, flyash enters the screening module by conveying mechanism 1, the screening module is sifted out impurity in the flyash and particle, flyash through screening enters agitator 3 by conveying mechanism 1,4 pairs of agitator 3 dosings of chemicals dosing plant, flyash forms coal ash pulp through the stirring of agitator 3, and coal ash pulp enters the flotation module through delivery pump 5, flotation column 6 in the flotation module and bubble generator 7 interact and overflow bubble, thereby separate to deviate from cleaned coal and tail ash.Separated cleaned coal and the tail ash of deviating from enters enrichment facility 9 by conveying mechanism 1, cleaned coal and tail ash are through the concentration of enrichment facility 9, enter the dehydration module 8 that is connected with enrichment facility 9, cleaned coal directly draws dried cleaned coal by dehydration module 8, and the tail ash draws dried tail ash by degas tube 81 and dehydration module 8.The charcoal process units is taken off in coal ash flotation of the present utility model, having solved coal-fired thermal power factory will take over the large tracts of land soil for use and build the problem of environmental pollution that the fine coal dust heap is filled out the storehouse and caused, precision by extracting flyash with separate the tail ash, reach reasonable and make full use of resource, improved utilization of coal ash value.
