As for the slag discharge device of the gasification furnace provided by the utility model, the functions of screening and slag crushing are integrated by arranging the slag crushing disk and the ash slag lattice in the slag receiving container, thereby effectively avoiding the blockage caused by ash slag and improving the slag discharge efficiency.
Description
Technical field
The utility model relates to a kind of slag discharging device, and relating in particular to a kind of is the vapourizing furnace slag discharging device of raw material with coal, refinery coke etc.
Background technology
In the equipment for gasification that with coal, refinery coke etc. is raw material, must the lime-ash that produce in time be discharged, and because ature of coal is different, it is also very big that lime-ash forms yardstick difference.The not enough 1mm of little particle diameter, big has hundreds of millimeters.Remove the ash fusion point of this part vapourizing furnace institute incendiary coal when higher; Also will produce gasifier temperature fluctuation slagging scorification or vapourizing furnace has the suspension slag that leaks chilling slagging scorification and cinder notch accumulation down to come off, and also exists temperature fluctuation refractory brick to peel off " the brick slag " of formation for Texaco's stove.Such slagging scorification will make down slag not smooth greater than following slag passage or when building bridge, then can't deslagging in the time of seriously.And cross when low at gasifier temperature when low-ash-fusion coal, incomplete combustion, before chilling just part to begin to form ash granular, ash content is higher; Make particulate state on the low side, water cut is too much, becomes the mud shape; Viscosity is big, can deposit in lock bucket bottom, builds bridge after the deposition compacting and blocks slag-drip opening.Produce stifled slag and will influence the vapourizing furnace ordinary production.Therefore the efficient of slag discharging device has become one of problem that influences the Coal Gasification Technology development.
Summary of the invention
The utility model technical problem to be solved provides a kind of vapourizing furnace slag discharging device, can effectively avoid lime-ash to stop up, and improves deslagging efficient.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to provide a kind of vapourizing furnace slag discharging device; Comprise and receive slag container, slag-drip opening and slagging coutrol valve; Wherein, saidly receive to be provided with in the slag container disintegrating slag dish and grey ballast screen lattice, said disintegrating slag dish is through central rotating shaft and wheel box connection.
Above-mentioned vapourizing furnace slag discharging device, wherein, said disintegrating slag dish is fan type, is made up of 4～6 disintegrating slag blades.
Above-mentioned vapourizing furnace slag discharging device, wherein, said disintegrating slag blade is provided with the disintegrating slag nail that is polygon pyramid shape.
Above-mentioned vapourizing furnace slag discharging device, wherein, said grey ballast screen lattice are square intersection grid, said grid spacing is 10mm～150mm.
Above-mentioned vapourizing furnace slag discharging device wherein, is provided with at least two agitating vanes on the said central rotating shaft.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe.
Fig. 1 is the utility model vapourizing furnace slag discharging device structural representation.
See also Fig. 1, the vapourizing furnace slag discharging device that the utility model provides comprises and receives slag container 9, slag-drip opening 7 and slagging coutrol valve 8, wherein, saidly receives to be provided with in the slag container 9 disintegrating slag dish 1 and grey ballast screen lattice 2, and said disintegrating slag dish 1 connects through central rotating shaft 3 and wheel box 5.
When lime-ash is tiny, can directly fall into and receive slag container 9 bottoms through grey ballast screen lattice 2.When the lime-ash that forms is bigger, can't when falling, grey ballast screen lattice 3 perhaps take place to build bridge when stopping up, and can start disintegrating slag dish 1 and regulate rotating speeds through wheel box 5 and carry out the disintegrating slag operation.
Above-mentioned vapourizing furnace slag discharging device, wherein, disintegrating slag dish 1 is fan type, is made up of 4～6 disintegrating slag blades 10; Can be provided with the disintegrating slag nail 11 that is polygon pyramid shape on the disintegrating slag blade 10, shown in Fig. 2 a and Fig. 2 b.
Above-mentioned vapourizing furnace slag discharging device, wherein, grey ballast screen lattice 2 are square intersection grid, said grid spacing is 10mm～150mm, and is as shown in Figure 3.
The vapourizing furnace slag discharging device that the utility model provides can further receive slag container 9 inwalls circumferentially evenly to arrange 8 or above water coolant nozzle 6; Water coolant nozzle 6 is positioned at disintegrating slag dish 1 top; Can cool off lime-ash like this, again because the turbulance of water has strengthened the disintegrating slag effect.
In addition, the above-mentioned vapourizing furnace slag discharging device central rotating shaft 3 of grey ballast screen lattice below 2 simultaneously is provided with agitating vane 4, and when the disintegrating slag operation was carried out in 1 rotation of disintegrating slag dish, agitating vane 4 synchronous stirrings can be avoided the deposition compacting of mortar, are difficult for stopping up.
The slag discharging device working process that the utility model provides is following: when receiving slag, can close slagging coutrol valve 8, can directly fall into lower bank cinder notch 7 places through grey ballast screen lattice 2 as suffered grey solid impurity particle is comparatively tiny.When grey solid impurity particle more greatly can't be when grey ballast screen lattice 2 fall; Just will be collected at above the disintegrating slag dish 1; This moment, disintegrating slag dish 1 rotated under the control of wheel box 5 through center rotating shaft 3, the macrobead lime-ash will be constantly and the disintegrating slag on the disintegrating slag dish blade 10 follow closely 11 and touch, reach the disintegrating slag purpose.When lime-ash fell, central rotating shaft 3 drove agitating vane 4 simultaneously and together rotates, and mortar is stirred, and avoid the mortar compacting to stop up, and lime-ash produced arch formation.Receive slag necessarily advance between after, can reduce central rotating shaft 3 rotating speeds, central rotating shaft 3 is stopped operating, open slagging coutrol valve 8 and carry out deslagging.The water of water coolant nozzle 6 ejections not only can reduce cindery temperature when receiving slag, in the disintegrating slag operation, also can strengthen the disintegrating slag effect because of the turbulence of water.Simultaneously when deslagging, also can reduce flying dust, alleviate air pollution.
Though the utility model discloses as above with preferred embodiment; Right its is not in order to limit the utility model; Any those skilled in the art; In spirit that does not break away from the utility model and scope, when can doing a little modification and perfect, so the protection domain of the utility model is when being as the criterion with what claims defined.
