Description
Technical field
The present invention relates to a kind of production technique and specific equipment thereof of coal water slurry.This coal water slurry can replace the heavy oil or the dregs of fat to use at all kinds of oil-firing boilers.
Background technology
Coal water slurry be a kind of coal-based liquid state for oil fuel, be divided into conventional coal water slurry, Coal Slurry and low heat value coal water slurry.Why coal slurry fuel can substitute oil, and its important characteristic is exactly to atomize rapidly with pump delivery with in stove as oil.
In the prior art, the production line of production coal water slurry and technical process are as shown in Figure 1.Raw coal utilizes jaw crusher to be broken into that coal dust is laggard goes into feed bin after the coal washing magnetic separation; The coal dust thin up that transports with belt from feed bin is after little ball milling is levigate, and through the sieve-bend screen screening, salable product enter vacuum extractor and dewater then; Coal dust after the dehydration is delivered to malaxator with belt, mediates add water and dispersion agent in malaxator after, and extruding is delivered to stirred pot and stirs then; After coal slurry after stirring is sent into big ball mill and carried out ball milling, deliver to the filter pulp jar again and carry out filter pulp; Salable product are sent in the slaking jar after maturation process, deliver to the finished product hold-up vessel and store.The shortcoming that this technology and equipment thereof exist is, operational path is fixed, and use equipment is more, and energy consumption is bigger; In addition, the coal slurry of making is because contained coal powder size is bigger, and it is higher to cause into slurry viscosity, and flowability is not good, and combustion conditions is comparatively harsh during use.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of coal water slurry production unit of technical process simple and flexible, utilizes the coal water slurry of this device fabrication, and contained coal powder size is less, becomes slurry viscosity lower.
The present invention adopts following technical scheme:
A kind of multistage once with multistage coal slurry apparatus production line repeatedly, comprise the coal washing magnetic separator successively, jaw crusher, mediate stirred pot, slaking jar and finished product hold-up vessel, between jaw crusher and slaking jar, configuration 2 covers in parallel or the above meticulous autogenous mill of 2 covers, mediate stirred pot, mixing and grinding machine and super grinder, the operation of optionally connecting each other between the mixing and grinding machine more than 2 or 2, the operation of optionally connecting each other between the super grinder more than 2 or 2, be the operation of optionally connecting, every suit mixing and grinding machine between jaw crusher and each meticulous autogenous mill, super grinder, be the operation of optionally connecting between the slaking jar.
The present invention is compared with prior art: saved operations such as little ball milling, sieve-bend screen, vacuum extractor and big ball milling, meticulous autogenous grinding, mixed grinding and extra-fine grinding operation have only been increased, therefore technical process is comparatively simple, use equipment is less, survey factually, production energy consumption is reduced to 27 kilowatts/ton by original 62 kilowatts/ton; Among the present invention, because the operation of optionally connecting each other between the mixing and grinding machine more than 2 or 2, the operation of optionally connecting each other between the super grinder more than 2 or 2 is so technical process is flexible.In addition, through the coal slurry that the present invention produces, the mean particle size of its contained coal dust is reduced to the 15-35 micron by 50 microns, thereby the one-tenth slurry viscosity that makes original coal slurry is reduced to 450-580 Ni Bo about by 1000 Buddhist nuns pool, has improved flowability, has reduced the combustion conditions when using.
