Deashing device 10 uses overflow deashing and 12 two-stage substep stagewise deashing device 10 of cleaning door, that is, uses clear water clear
It washes and takes away part little particle dust, remaining bulk dust is removed by cleaning door 12.Deashing device 10 includes cavity, is set on cavity wall
There are water inlet 14, water outlet 16, nitrogen inlet 11, nitrogen outlet 9 and cleaning door 12, water inlet 14 to be placed in 16 lower section of water outlet,
Nitrogen inlet 11 is placed in the lower section of nitrogen outlet 9, and cleaning door 12 is placed in cavity bottom, when overflow deashing, closes cleaning door 12, water inlet
14 water fillings of mouth, little particle dust is as flow is from the discharge of water outlet 16, and nitrogen inlet 11 leads to nitrogen simultaneously for water filling, and agitation is sticked in device
Dust on wall, which incorporates in water, to be discharged；Finally, it opens cleaning door 12 and the dust for being accumulated in 10 bottom of deashing device, cleaning door is discharged
12 use hydraulic pressure valve port, and work of the long-range temperature probe 13 of hydraulic pressure valve port for monitoring hydraulic pressure valve port in real time is arranged at cleaning door 12
Temperature, the cleaning temperature of effective monitoring deashing device 10 help to reasonably select the deashing time, avoid valve port temperature is excessively high from causing
Harmful effect；
The course of work
Gas enters cyclone cylinder by air inlet 2, rotates in high-order cyclone cylinder 3, by centrifugal force by part dust
Barrel is detached and heaps, the dust of heap declines along barrel；When whirlwind reaches low order cyclone cylinder 7, high speed winds are by whirlwind
Speedup ventilation opening 5 is passed through, and improves the wind speed of whirlwind, and in the case where rotary inside diameter is smaller, centrifugal force increases, by formulaSimilarly, dust separation heaps to barrel and declines；When whirlwind arrival spiral shape backflows damping screen 6, flow velocity subtracts
It is small；So far, gas up flows among cyclone cylinder, and dust is along the second cone cylinder inner wall sinking heap below the damping screen 6 that backflows
Collection waits for the isolated electro hydraulic valve of interval to be opened every 8 valve of apparatus for ash and collects dust；The mistake that gas up flows among cylinder
Cheng Zhong, drives broken rotation to disturb the rotation of dirt device 4, and broken rotation disturbs dirt device 4 and rotates the residual dust particle disturbance so that in gas, part
Dust, which can enter in whirlwind, to be dusted；The gas stream intake and exhaust cylinder 1 that dirt device 4 is disturbed by broken rotation, through the drum on exhaust tube 1
Bubble, gas slows down when entering bubbling, and is accumulated at bubbling, sinks by gravity, carries out final dusting.
The dust of collection is stored in deashing device 10, is classified using overflow ash discharge and 12 ash discharge two ways substep of cleaning door
It carries out；Cleaning door 12 close when, 14 water filling of water inlet, little particle dust with flow from water outlet 16 be discharged, water filling simultaneously nitrogen
Gas entrance 11 leads to nitrogen, and agitation is sticked to be discharged in the involvement water of the dust on wall；Finally, cleaning door 12 is opened, discharge is accumulated in
The dust of 10 bottom of deashing device.
The preferred embodiment of the present invention is above are only, the present invention is not limited in the content of embodiment.For in this field
Technical staff for, can have various change and change within the scope of technical scheme of the present invention, made by it is any variation and
Change, within the scope of the present invention.
