Description
Technical field
The utility model relates to a kind of sludge circulating fluid bed CIU, belongs to Sludge Disposal Techniques field.
Background technology
Along with the discharge capacity of urban industry waste water and sanitary sewage is increasing, treatment rate of domestic sewage also improves year by year, the sludge yield of municipal sewage plant also sharply increases, a large amount of excess sludges will discharge in sewage treatment plant, the mud of enormous amount need to be done further processing, if mud can not get reasonable processing, will cause secondary pollution.The composition of sewage sludge is very complicated, except containing a large amount of moisture, also containing a large amount of useful resources.For urban sludge treating method, have at present multiplely, generally have landfill, burning and comprehensive utilization, but before recycling, need carry out pretreatment to mud, nurse one's health, comprise concentrated, dehydration, dry.Because sludge quantity is larger, mummification need to consume the energy, and cost is very high, and landfill is wasted again land resource, and mud self has certain calorific value, therefore can burn the disposal that realizes mud.
Utility model content
The purpose of this utility model is to provide a kind of sludge circulating fluid bed CIU, utilizes the combustion-supporting material of a small amount of high heating value, and mud is easy to burning in recirculating fluidized bed, effectively utilizes waste-gas heat for generating, and is being provided with deduster and absorber purifying exhaust air.
The purpose of this utility model is achieved through the following technical solutions: a kind of sludge circulating fluid bed CIU, mainly by sludge bin, coal bunker, entry mixers, circulating fluidized bed incinerator, device for igniting, ash bucket conveyer, cyclone separator, waste heat boiler, steam turbine generator, air-introduced machine, deduster and absorber, formed, it is characterized in that: described circulating fluidized bed incinerator bottom is provided with taper bucket, and is provided with device for igniting in the side of taper bucket; Described circulating fluidized bed incinerator top vent connects cyclone separator, waste heat boiler, air-introduced machine, deduster and absorber successively.
The bottom of described cyclone separator is provided with ash bucket conveyer, and ash bucket conveyer is connected with entry mixers.
Described entry mixers is connected with the taper bucket of circulating fluidized bed incinerator bottom.
In sum, the beneficial effects of the utility model are: mud enters circulating fluidized bed incinerator inside from sludge bin by entry mixers, by coal bunker, add combustion-supporting material, utilize the combustion-supporting material of a small amount of high heating value; Because mud mobility is better, mud is easy to burning in recirculating fluidized bed; Effectively utilize waste-gas heat for generating; And be provided with deduster and absorber purifying exhaust air.
