Description
Technical field
The utility model belongs to the solid waste treatment facility scope, is specifically related to a kind of washing pretreatment system flying dust storage tank that domestic garbage incineration flyash is handled.
Background technology
Along with the fast development of waste incineration in China, as the inevitable outcome in the waste incineration, the output of flying dust is also soaring year by year in recent years.Incineration of refuse flyash has heavy metal and leaches the high and big dual hazard profile of dioxin toxic equivalent of concentration, belongs to dangerous waste, and it is numbered HW18 in China's " national dangerous waste register ".
The chemical constitution of flying ash is similar to the siliceous or calcareous raw material of cement, can substitute the part natural material, also can partly or entirely replace siliceous or calcareous raw material.Temperature of charge is up to 1450 ℃ in the cement rotary kiln, gas temperature then up to 1750 ℃ about, can thoroughly decompose bioxin, an effectively fixing huge sum of money belongs in the grog lattice, the product that the incineration fly ash cement kiln coexistence is put is a cement, does not have waste residue to produce.At the difficult problem of present flying dust disposal and the environmental hazard that brings, utilize the cement kiln synergic processing flying dust to save natural material for cement industry, reducing emission of carbon dioxide, and the disposal and the operating cost of reduction flying dust are realized changing waste into resources and innoxious high unity.
Flying dust advances the chlorine that needs to remove through the washing pretreatment too high levels before kiln is handled, and the flying dust storage tank is as the temporary transient flying dust that stores, and the container that supplies raw material is used widely.Flying dust washing or the laggard landfill yard of pickling are disposed and are also needed to use the flying dust storage tank in addition.At present, storage bin for flyash that flying dust pretreatment system or cure system are used or storage tank, generally be provided with inlet point on the top, utilize inlet point in storage tank, to transmit flying dust, bottom bucket type discharging, with the surplus of flying dust in the artificial judgment storage tank, thereby whether decision is augmented flying dust or is stopped charging in storage tank.This structure can't effectively prevent airborne dust, and subsidiary dioxin can suck human body by the skin contact in the flying dust, easily the operator is caused health hazard.Light owing to flying dust density in addition, fine size, bridging in container, bridge formation or caking easily.
The utility model content
The purpose of this utility model is to be provided with inlet point at flying dust characteristic and existing storage tank on the top, utilize inlet point in storage tank, to transmit flying dust, bottom bucket type discharging, with the surplus of flying dust in the artificial judgment storage tank, thereby whether decision is augmented flying dust or is stopped charging in storage tank.This structure can't effectively prevent airborne dust, and subsidiary dioxin can suck human body by the skin contact in the flying dust, easily the operator is caused health hazard.In addition because flying dust density is light, fine size, bridging in container easily, the defective that storage tanks such as bridge formation or caking exist, and a kind of washing pretreatment system that provides flying dust storage tank, it is characterized in that, the tank body main body top of described flying dust storage tank is cylindrical, the bottom is conical, flying dust storage tank top is inlet point and feed pipe, duct cyclone and sack cleaner are set on the top cover, there is the double-deck frame that stirs at the tank body center, and first visor is installed on tank body top and conical base is installed second visor, at the flying dust storage tank conical base hopper wall vibrator of connecting successively from top to bottom, the bottom butterfly valve, Pneumatic conveyer, discharging opening and discharge nozzle; Bracket leg is held in flying dust storage tank tank body outer conical surface middle part.
Described flying dust storage tank tank body material adopts carbon steel, in be coated with epoxy glass squama antiseptic paint.
Advantage of the present utility model: the flying dust storage tank withstanding corrosion that this patent provides, anti-bridging bridge formation, convenient demonstration material level, input and output material sealing, supporting closely with flying dust washing pretreating process, the Pneumatic conveyer of cement bulk car is used in charging, discharging also is transported in the washing process underwater in the washing pool with Pneumatic conveyer with flying dust, effectively prevents airborne dust.This patent is with the safe storage of lower cost realization flying dust, and input and output material effectively prevents secondary pollution, and can prevent a jar interior flying dust bridging, bridge formation or caking, has reduced workman's working strength and health hazard.
Description of drawings
Fig. 1 is the structural representation of the utility model example.
The specific embodiment
The utility model provides a kind of washing pretreatment system flying dust storage tank.Shown in Figure 1 is the structural representation of the utility model example.Below in conjunction with Fig. 1 the utility model example is introduced.
As shown in Figure 1, the tank body main body top of the flying dust storage tank that the utility model provides is cylindrical, the bottom is conical, flying dust storage tank top is inlet point and feed pipe 1, duct cyclone 2 and sack cleaner 3 are set on the top cover, there is two-layer stirring frame 4 at the tank body center, and second visor 6 of first visor 5 and conical base is installed on the tank body, at flying dust storage tank conical base connect successively from top to bottom hopper wall vibrator 7, bottom butterfly valve 8, Pneumatic conveyer 9, discharging opening 10 and discharge nozzle 11; Support 12 is supported in flying dust storage tank tank body outer conical surface middle part.Because the flying dust strong basicity, flying dust storage tank tank body material adopts carbon steel, in be coated with epoxy glass squama antiseptic paint.
The input and output material of flying dust storage tank all adopts Pneumatic conveyer to pass through long progress/discharge nozzle and carries, charging by cement bulk car air pressure discharging finish, discharging is controlled by butterfly valve, Pneumatic conveyer is carried, through discharge nozzle to the washing equipment underwater.Duct cyclone and bag dust collector are installed in the tank body top simultaneously, and airborne dust in the time of can reducing input and output material to greatest extent reduces the health hazard to the operator.
Flying dust storage tank tank body top and the bottom all are equipped with visor, to show material level.When the flying dust material level is higher than the top visor, stop charging, when material level is lower than the bottom visor, should feed supplement.
The double-deck frame that stirs is housed in the flying dust storage tank jar, in the storage tank conical base hopper wall vibrator is installed simultaneously, to prevent bridge formation, bridging or obstruction in the flying dust storage tank.
Flying dust is moved flying dust pretreatment place, cement mill from garbage burning factory to by the cement bulk car, feed pipe is linked to each other with the cement bulk car, when reaching certain pressure, open the discharging butterfly valve, the cement bulk car blows flying dust to the flying dust storage tank by pressurized air, when stop charging by 5 controls of first visor, duct cyclone 2 and bag dust collector 3 can effectively prevent dust pollution.Directly flying dust is transported to the water scrubber underwater by Pneumatic conveyer 9 by discharge nozzle 11 during discharging, effectively prevents airborne dust.Two-layer stirring frame 4 in the tank body intermittently stirs, and the hopper wall vibrator 7 of pot bottom passes through effectively to prevent bridging, bridge formation and caking at the bottom of the vibration flying dust storage tank jar.Judge whether need charging by second visor 6.
