In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.

Accompanying drawing is a kind of structural representation of seperator of ash and water

This seperator of ash and water because in the tank body bottom, the water inlet pipe place is equipped with tubular type injection of separation device, in the separator, nozzle 1 is in hydroecium 2, the port of export that its input is connected with water inlet pipe 16, trunnion 3 is installed in hydroecium constitutes first reative cell; Anemostat 4, water cover 5 are installed in the port of export of trunnion successively, constitute second reative cell.Like this, the dense grey pulp-water that contains the suspension object height, by ash pump from the water inlet pipe input nozzle, spray at a high speed by nozzle, nozzle place in the hydroecium forms vacuum, negative pressure occurs on every side, a large amount of dense grey pulp-waters are sucked repeatedly from the through hole 6 on the hydroecium wall, promptly are in the high-speed stirred state at first reative cell; Dense grey pulp-water enters anemostat through trunnion with high speed simultaneously, carry out violent and mixing fully, collision and power conversion at this, the buck that sprays at a high speed through anemostat is subjected to stopping of water cover again, keep the high-speed stirred state at second reative cell, grey molecule is separated rapidly with hydrone, and then changed the moving law of electronics on its track of grey molecule, and make grey molecule attract each other, flocculate into bulky grain, be deposited in the slag bucket very soon.Dense grey pulp-water by twice high-speed stirred separate, post precipitation, the filtration of device after filtration again, the Ash Water Separator effect obviously improves.

Among the embodiment of seperator of ash and water shown in the accompanying drawing, it also is provided with the expansion chamber 7 that is made of the filler swash plate on the top of tubular type injection of separation device.The grey particulate of sedimentation does not rise in the expansion chamber of being made up of four strata vinyl chloride filler swash plates further separated, sedimentation.

Among the seperator of ash and water embodiment, be provided with the absorption clarifying chamber 8 that constitutes by expandable polystyrene filter pearl again on the top of expansion chamber.Make remaining grey particulate be adsorbed, clarify, tentatively filter at this.

In order to improve the filter effect of filter in this seperator of ash and water, be positioned at the filter on top, adsorption clarification chamber, be cast iron chimney filter 9 to be fixed on the structure that overflow plate 10 bottoms are constituted with flange.The cast iron chimney filter is by an end cast iron pipe porose on flange, the tube wall to be arranged, the every structure that cast iron pipe outer cover nylon wire constitutes.Make grey particulate continue to be adsorbed, to clarify, be filtered once more, the water after the processing overflows through overflow plate, and filter effect is good.
