Description
Technical field
The utility model relates to a kind of fume dust remover, specifically relates to the fume dust remover in a kind of alumina producing
Background technology
In alumina producing, the recirculating fluidized bed roaster is one of a kind of industrial equipment that the typical case who obtains the product aluminium oxide after the high-temperature roasting of wet hydrogen alumina material is used, one of characteristics of this roasting system are exactly that the high-temperature flue gas that roasting master stove comes out is sloughed attached water with the wet hydrogen alumina material that enters after venturi drier 2 is mixed preheating, enter then in the electrostatic precipitator 4 solid material is collected, adopt gas-phase transport in expansion storehouse 7 with air lift mud pump 5, send into again and carry out roasting in the roasting master stove and obtain product.But this kind flue gas ash removal flow process is owing to only adopted 4 one dust collection devices of electrostatic precipitator, so the ability of gathering dust of its electrostatic precipitator 4 is bigger, and the complete machine electrical power is bigger, the energy consumption height.Because all material all enters in the electrostatic precipitator 4, so dustiness is higher in the discharged flue gas, influential to environment, loss of material is more relatively.And through electrostatic precipitator 4 collected whole materials again by air lift mud pump 5 gas-phase transport to expansion storehouse 7, and the power of air lift mud pump 5 provides by high pressure positive blower 6, so the load of high pressure positive blower 6 is higher, energy consumption is also higher.
Summary of the invention
Problem to be solved in the utility model provides a kind of ciculation fluidized fume dust remover, and its dust-collecting efficiency height, energy consumption is low and economic, easy enforcement, has both reduced the energy consumption of cleaner, has improved in the fume emission dust concentration again to the influence of surrounding environment.
In order to address the above problem, the utility model provides a kind of ciculation fluidized fume dust remover, it comprises feed bin 1, venturi drier 2, electrostatic precipitator 4, feed bin 1 connects venturi drier 2, the upper end of venturi drier 2 connects the top of electrostatic precipitator 4 by pipeline, the lower end of electrostatic precipitator 4 connects air lift mud pump 5 through pipeline, air lift mud pump 5 links to each other with high pressure positive blower 6, air lift mud pump 5 connects 7 tops, expansion storehouse through the gas-phase transport pipeline, 7 bottoms, expansion storehouse are connected recirculating fluidized bed roaster system 8 with the upper end by pipeline, and the upper end of recirculating fluidized bed roaster system 8 connects the lower end of venturi drier 2 again by pipeline.Between venturi drier 2 and electrostatic precipitator 4 by cyclone dust collectors 3, the import of cyclone dust collectors 3 links to each other through the upper end of pipeline with venturi drier 2, the upper end outlet of cyclone dust collectors 3 links to each other with electrostatic precipitator 4 through pipeline, and the lower end of cyclone dust collectors 3 exports on the gas-phase transport pipeline that is connected between air lift mud pump 5 and the expansion storehouse 7.
Electrostatic precipitator 4 is provided with flue gas discharge opening.
Compared with prior art, the utility model is by increasing one-level cyclone dust collectors 3, make the load that gathers dust that enters electrostatic dust collection equipment significantly reduce, thereby specification of equipment, complete machine electrical power and the energy consumption of electrostatic precipitator 4 have been reduced, saved investment and operating cost, and made the exhaust gas dust concentration of discharging atmosphere much smaller than discharging standards.After adopting device for modifying of the present utility model, significantly reduce from electrostatic precipitator 4 collected materials, the feasible load of the air lift mud pump 5 of this material of carrying reduces, and provides the ability and the power of motor of the high pressure positive blower 6 of power also can correspondingly to reduce, thereby has reduced energy consumption.In addition, the cyclone dust collectors 3 of increase are without any need for extra power, and only the flow velocity by flue gas itself can carry out dedusting, and the drag losses of cyclone dust collectors is less, can ignore in the line loss of flue gas.
