Abstract
Disclosed is a long-distance coarse particle coal transportation pipeline terminal storage device and method. The long-distance coarse particle coal transportation pipeline terminal storage device comprises a pipeline heater, a coal transportation pipeline, a sedimentation filtration type centrifuge, a slurry storage tank, a thickener and a sewage disposal plant. Coal slurry in the coal transportation pipeline enters the sedimentation filtration type centrifuge for dewatering after being heated by the pipeline heater, and the dewatered product is transported to the slurry storage tank. Filtrate of the sedimentation filtration type centrifuge enters a sedimentation centrifugal liquid cylinder and is conveyed to the thickener through a pump for concentration. Bottom flow of the thickener is conveyed to a mixing cylinder through the pump, and coal slurry in the mixing cylinder is conveyed to the slurry storage tank through the pump after being mixed. Overflow of the thickener is conveyed to the sewage disposal plant through a pipeline. The high-concentration coal slurry in the slurry storage tank can be directly supplied to a coal chemical industry user for using. The long-distance coarse particle coal transportation pipeline terminal storage device has the characteristics of being simple in structure, convenient to install and use, and good in concentration effect and concentration difference controllability and is widely applied to the long-distance pipeline coal transportation industry.
Description
Technical field
The present invention relates to convey coal pipe terminal storage device, be specifically related to a kind of long distance coarse particle convey coal pipe terminal storage device and method.
Background technology
The coal slurry weight concentration of long distance coarse particle convey coal pipe conveying is generally 50% to 60%, and maximum particle size is greater than 6 millimeters, and mean grain size is greater than 1 millimeter.Because fed distance is long, freight volume is large, so the fender system of larger capacity need be arranged in long distance coarse particle convey coal pipe terminal, be generally a few ten thousand stere, sometimes can reach hundreds of thousands of cubic meter.But, manage in defeated coal slurry the coarse particle fall velocity being greater than 1 millimeter very fast, when adopting mechanical agitation mode in storage process in slurry can, need very large kinetic energy coarse particle could be held up to suspend, therefore, very high in the energy consumption of the storage facility of terminal setting, in long term storage whipping process, cause great energy dissipation.
Summary of the invention
The object of this invention is to provide a kind of structure simple, process procedure is few, easy to install, the long distance coarse particle convey coal pipe terminal storage device that energy consumption is low.
Another object of the present invention is to provide convey coal pipe terminal storage method.
In order to overcome the deficiencies in the prior art, technical scheme of the present invention solves like this: a kind of long distance coarse particle convey coal pipe terminal storage device, comprise screen bowl centrifuge, filtrate stirred pot, coal slurry pump, manage defeated coal slurry stirred pot, slat conveyer, coal yard, to weigh band conveyor, special character of the present invention is that described screen bowl centrifuge filtrate product is connected with described filtrate stirred pot, the tank skin outlet at bottom of described filtrate stirred pot is connected with described coal slurry pump by pipeline, described coal slurry pump outlet is connected by the defeated coal slurry stirred pot of pipeline and described pipe, described screen bowl centrifuge dehydrating prods is connected with the feeding end of described slat conveyer, the discharge end of described slat conveyer is connected with described coal yard, described coal yard is connected with described band conveyor of weighing.
A convey coal pipe terminal storage method for described device, carries out successively in the steps below:
1), manage defeated coal slurry enter screen bowl centrifuge dehydration after filtrate product enter buffer storage in filtrate stirred pot;
2), filtrate enters coal slurry pump force (forcing) pump from the tank skin outlet at bottom of filtrate stirred pot by pipeline and delivers in the defeated coal slurry stirred pot of pipe;
3) the coal slime product, after screen bowl centrifuge dehydration is delivered in coal yard through slat conveyer and stores;
4), coal slime from coal yard, enters in the defeated coal slurry stirred pot of pipe, is uniformly mixed together with filtrate after band conveyor Weighing of weighing.
The beneficial effect of this length distance coarse particle convey coal pipe terminal storage device: adopt coal yard form to store by being separated by coarse particle in defeated for pipe coal slurry, save the energy consumption between the storage life, apparatus structure is simple, process procedure is few, easy to install, be widely used in long distance coarse particle convey coal pipe industry.
