Abstract
The present invention relates to a superfine high-density coal water slurry production system which is composed of a superfine crusher, a stirring feeder, a tower type colloidal mill, a coal slurry pump, a fine powder collector and a rationing powder feeder. The present invention changes the production method of the existing coal water slurry, integrates dry milling and wet milling, and regulates the concentration of coal slurry so as to realize that milling and pulping can be finished once in a production system; the fineness of coal powder can reach more than 600 meshes. The present invention has the advantages of small occupation areas, high safety, no pollution and high efficiency, and is ideal environmental protection equipment.
Description
The present invention relates to superfine high-density coal-water fluid producing system.
At present, a large amount of exploitations along with subterranean resource, make fuel resource shortage day by day, and coal water slurry is the ideal substitute of fuel oil, and the concentration of contained fineness of pulverized coal of coal water slurry and coal water slurry directly influences the effect that coal water slurry substitutes fuel oil, cause above-mentioned reason with the equipment and the production technique of current production coal water slurry direct reason to be arranged again,, but all do not have better method for the concentration problems of the fineness that better solves coal dust and coal water slurry also is both at home and abroad all in the problem of research.
The making of coal water slurry at first is the grinding of coal, at present, the grinding coal dust has two kinds of dry method and wet grindings, though the dry method grinding can improve the fineness of coal dust, fineness of pulverized coal also can only reach 180 orders-300 order, and the equipment that is used for dry method grinding coal dust in process of production, seriously exists inflammable and explosive unsafe factor, though wet grinding is than imitating safety, but its device fabrication goes out fineness of pulverized coal is difficult to reach requirement, and produce complexity, and the coal dust behind the grinding is made coal water slurry, all adopt settling process and centrifugal filtration process both at home and abroad, settling process is carried out sedimentation with mixture of coal exactly in settling bowl, this kind method floor space is big, and sedimentation is long cycle time, and efficient is extremely low, and centrifugal filtration process, then can make coal dust when centrifuging, loss part coal dust, nor the requirement of adaptation industrialized production.
The objective of the invention is to overcome the problems referred to above, provide a kind of the grinding of coal and the making of coal water slurry are integrated, and connection and reasonable arrangement, floor space is little, can realize the superfine high-density coal-water fluid producing system of industrialized production.
To achieve these goals, technical solution of the present invention is a superfine high-density coal-water fluid producing system, its production system is by the ultrafine powder pulverizer, and agitator-conveyor, tower colloidal mill, coal slurry pump, dispersator, fine powder collector, quantitative powder feeding equipment constitute.Slurry relief outlet, coal slurry pump, tower colloidal mill, dispersator pipe connection on dried fine powder relief outlet on the ultrafine crusher 1 body top and fine powder collector pipe connection, agitator-conveyor and the intravital cone of ultrafine crusher machine, coal slurry pump is installed in tower colloidal mill both sides respectively.Quantitatively powder feeding equipment is used to regulate the fine powder amount that enters dispersator, quantitatively powder feeding equipment top interface and fine powder collector pipe connection, bottom interface and agitator-conveyor pipe connection.
Owing to adopted above technical scheme, production system of the present invention can change the mode of production of existing production coal water slurry, its collection dry method grinding and wet method are one, and adjustable water saving coal-water fluid concentration, and grinding, slurrying are once finished in production system, and fineness of pulverized coal can reach more than 600 orders, its floor space is little, and security is good, and is pollution-free, the efficient height is the ideal environmental protection equipment.
Below in conjunction with drawings and Examples the present invention is described in further detail.
Accompanying drawing is a production system synoptic diagram of the present invention.
See accompanying drawing 1:
Superfine high-density coal-water fluid producing system, by ultrafine crusher 1, agitator-conveyor 2, tower colloidal mill 4, coal slurry pump 3,5, disperse agitator 6, fine powder collector 7, quantitatively powder feeding equipment 8 constitutes, dried fine powder relief outlet 9 and fine powder collector 7 pipe connection on the ultrafine crusher 1 body top, slurry relief outlet 18 on agitator-conveyor 2 and the intravital cone 10 of ultrafine crusher 1 machine, coal slurry pump 3,5, tower colloidal mill 4, dispersator 6 pipe connection, coal slurry pump 3,5 are installed in tower colloidal mill 4 both sides respectively, quantitatively powder feeder 8 is used to regulate the fine powder amount that enters dispersion agitator 6, quantitative agitator 8 top interface pipe connection fine powder collectors 7, bottom interface pipe connection disperses agitator 6.Agitator-conveyor 2 is installed in ultrafine crusher 1 body.Tower colloidal mill 4 and dispersion agitator 6 tops also are respectively equipped with the external interface 15,16 for water filling or additive, and ultrafine crusher 1 body inner cone 10 is provided with the external interface 14 for water filling or additive.
Embodiment:
The making production of superfine high-density coal-water fluid: ultrafine crusher adopts the DJM900 ultrafine crusher.Dried raw coal opening for feed 17 from the DJM900 ultrafine crusher body enters in the machine, and in machine, feed fire-retardant gas, it is broken under the Thumper 11 of high speed rotating impacts, and formation rotation stock column upwards, wherein contain a large amount of fine powders, when fine powder runs into material distributing plate 13, fine powder continues upwards, classified device 12 fine powders enter fine powder collector 7 along the dried fine powder relief outlet on the body top 9 along pipeline and collect, undesirable meal then falls in the cone 10, in cone, inject water and additive by the external interface 14 that is located on the cone 10, and make coal dust and the water that falls in the cone 10, additive is sent into agitator-conveyor 2 together, through the helical stir pulp and send outside the machine, enter coal slurry pump 3 through pipeline, by coal slurry pump 3 slurry is injected tower colloidal mill 4 again, inject additive from being located at tower colloidal mill 4 top external interfaces 15, slurry reaches ultra-fine coal slurry greater than 600 order fineness through tower colloidal mill 4 multistage fine grindings, for improving coal-water fluid concentration, with coal slurry pump 5 ultra-fine coal slurry is injected dispersator 6, open quantitative machine supplying powder 8 simultaneously, by the requirement of high density coal slurry coal slurry is regulated, quantitatively add dispersed with stirring devices 6 in through quantitative powder feeding equipment 8 microfine coal of collecting from the DJM900 main frame in advance, disperse agitator 7 top external interfaces 16 to inject additive through being located at again, fully dispersed with stirring becomes superfine high-density coal-water fluid.
