Material warehouse (31) stores the carbon dust for preparing, when bringing into operation, all valves are in closing condition, at first valve A opens, enter feed pot A(32 by the action of gravity material), close etc. the reinforced back valve A that finishes, carry the pressurization of air to open beginning, when being forced into transfer pot (34) uniform pressure, stop pressurization, valve C opens, by gravity, material enters transfer pot (34), during this blanking, feed pot B(33) reception is from the material of material warehouse (31), as feed pot A(32) after discharging finishes, shut-off valve C, and open valve E and give feed pot B(33 with the overbottom pressure of the inside) punching press, valve E closes after the pressure equalization, and valve F opens pressure release to normal pressure, carry gas to continue to feed pot B(33 simultaneously) continue to be forced into and transfer pot (34) equipressure, valve D opens by gravity dumping to transfer pot (34) then, and transfer pot (34) convey materials is constantly given in the continuous operation that goes round and begins again like this, transfer pot is connected with conveying gas in (34), carry the moving carbon dust of the band of gas to carry, a variable valve is arranged at transfer pot (34) bottom, thereby by the mass transport amount in the aperture size adjusting unit time of regulated valve;
Mass transport is to the module that gasifies (4), and material powder combined vaporizing agent is here carried out high-temperature gasification at this, generates product in the gasification and comprises: effective gas, lime-ash, and cooling waste water;
Lime-ash enters deslagging module (5), deslagging module (5) top and the bottom all are connected with the gasification module, during normal the operation, upper valve is opened, the bottom valve closes, after lime-ash is full of, upper valve is closed, outside the valve open discharge system of bottom, after discharge finishes, lower valve closes closes valve open, continues the lime-ash of a new round and collects;
The effective gas of dust-laden from gasification module (4) is sent to wash module (6), at first gas enters Venturi meter (61), wash, gas-liquid-solid mixture after the washing enters cyclonic separation (62) to be separated, get rid of oarse-grained lime-ash and waste water here, and then entering washing tank (63) again washs, washing tank (63) bottom is water-bath, the middle part is column plate (632), the top is scum dredger (631), scrubbing body to be washed enters the bottom water-bath via sedimentation gas distribution pipe (633) lower end aperture, gas is separated into small bubbles through broken bulb apparatus (634) and rises, enter separating tank (64) after the washing of small bubbles process water-bath and column plate hydrops and the foam removal, separating tank (64) has a bearing shell, the sinuous coil (641) that inside has the several layers of certain wall thickness steel tube of usefulness to make, the outside recycle pump that connects of sinuous coil (641), recycle pump forces the cold water in the sinuous coil (641) constantly to flow, the gas that is full of water vapour through the cooling of sinuous coil (641) after temperature reduce and condensation goes out a part of liquid, the gas comparison drying that becomes relatively, send system after the scum dredger (631) that condensed liquid continues to rise to the top is removed fine droplet, wherein the water that flows in the sinuous coil (641) is taken heat out of for the production of low-pressure steam;
High Temperature High Pressure waste water from gasification installation enters water treating module (7), High Temperature High Pressure waste water at first enters hydraulic turbine (71), by hydraulic turbine (71) recovery high pressure potential energy wherein, and then enter flasher (72) and carry out flash distillation, the pressure and temperature reducing water that generates after the flash distillation is recycled, the steam that generates enters heat recovery tower (73) and carries out heat recuperation, cold water injects from top tray in the heat recovery tower, steam sprays from cloth gas cap (731), carry out heat exchange at column plate (632), low temperature waste gas after the heat exchange discharges, and the hot water reservoir (732) that the hot water after the heat exchange enters at the bottom of the tower is recycled.
