Abstract
A concentration-increasing system device for coal slurry at the end of a long-distance coal conveying pipeline comprises a pipeline heater, a coal conveying pipeline, a sedimentation filtration type centrifuge, a slurry storage tank, a thickener and a sewage treatment plant. Coal slurry in the coal conveying pipeline is heated by the pipeline heater, enters the sedimentation filtration type centrifuge to be dehydrated, and the dehydrated product is conveyed to the slurry storage tank; filter liquor of the sedimentation filtration type centrifuge enters a sedimentation centrifugation liquid bucket, and is conveyed to the thickener by a pump to be concentrated; underflow of the thickener is conveyed to a stirring bucket by a pump; coal slurry in the stirring bucket is stirred and conveyed to the slurry storage tank by a pump; overflow of the thickener is conveyed to the sewage treatment plant through a pipeline; high-concentration coal slurry in the slurry storage tank can be directly supplied to users in the coal chemical industry for use. The concentration-increasing system device has the characteristics of being simple in structure, convenient to mount and use, good in concentration-increasing effect and good in concentration difference controllability, thereby being widely applied to the long-distance pipeline coal conveying industry.
Description
Technical field
The present invention relates to coal slurry concentration unit, be specifically related to a kind of long distance convey coal pipe terminal coal slurry upgrading system device and method.
Background technology
The coal slurry of long-distance transportation through pipeline is generally middle concentration coal slurry, weight concentration is 45% to 55%, and the coal slurry that Coal Chemical Industry user uses is generally high concentration coal slurry, and weight concentration is 60% to 65%, therefore, need to carry out concentrate to long-distance transportation through pipeline to the coal slurry of terminal.Before apparatus of the present invention are made, there is no special device and method for the coal slurry concentrate of terminal, so cause long distance convey coal pipe to be subject to great restriction when being applied to the Coal Chemical Industry that terminal use is use high concentration coal slurry, time serious, the coal slurry causing terminal a large amount of cannot be processed.
Summary of the invention
The object of this invention is to provide a kind of structure simple, easy to install, concentrate is effective, the long distance convey coal pipe terminal coal slurry upgrading system device that concentration difference controllability is good.
Another object of the present invention is to provide terminal coal slurry concentrating 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 convey coal pipe terminal coal slurry upgrading system device, comprise pipeline heater, convey coal pipe, screen bowl centrifuge, slurry can, thickener, sewage treatment plant, special character of the present invention is that described pipeline heater is arranged on convey coal pipe, described convey coal pipe one end is connected with described screen bowl centrifuge, after described screen bowl centrifuge dehydration, product is connected with described slurry can by ribbon conveyer, described screen bowl centrifuge underflow product is connected with described thickener by a pump and pipeline, described thickener underflow one end is connected with described slurry can by two pumps and pipeline, described thickener overflow one end is connected with described sewage treatment plant by pipeline.
A terminal coal slurry concentrating method for described device, carries out successively in the steps below:
1) coal slurry, in convey coal pipe is after pipeline heater heating, and enter screen bowl centrifuge dehydration, after dehydration, product is transported to slurry can;
2), the filtrate of screen bowl centrifuge enters sedimentation centrifugate bucket, concentrated to thickener by transport pump, thickener underflow by transport pump to agitator, the coal slurry in agitator after stirring by transport pump to slurry can;
3), thickener overflow by Cemented filling to sewage treatment plant.
The beneficial effect of this long distance convey coal pipe terminal coal slurry upgrading system device: concentrate is effective, concentration difference controllability is good, convey coal pipe is installed coal slurry heater and further enhancing concentrate effect, the concentration difference improving concentration effectively can be controlled by the underflow and overflow ratio controlling thickener, apparatus structure is simple, easy to install, be widely used in long-distance pipeline coal industry.
