Description
Technical field:
The utility model relates to the water-coal-slurry device of a kind of employing with the high efficiency that is different from traditional coal-water-slurry technology of raw coal " in small, broken bits+pre-grinding+two stage grinding ", high concentration, high rheological characteristic, can realize many variety production of water-coal-slurry.
Background technology:
The coal new high-tech product that water-coal-slurry occurs when being late 1970s international petroleum crisis, it is the fluid that is formed by the microchemistry additive preparation about the water of the coal dust of 65%-70% and 29%-34% and 1%.The outward appearance picture oil of water-coal-slurry, accumulating picture oil blazes up also as oil.Water-coal-slurry can be stable fire burns, both kept the burning of coal characteristic, possessed the liquid fuel application characteristic of similar heavy oil again.Water-coal-slurry is the most real a kind of a, coal based fluid fuel efficiently, also be that a kind of preparation is simple relatively, be convenient to carry store, safe and reliable, oligosaprobic novel clean fuel, the best alternative fuel of " to starch ", energy savings, reduction fuel cost especially for coal.The newcomer who belongs to fuel family, the important component part of current clean coal technology.
Relatively under the situation of shortage, replace oil with coal is fit to the national conditions of China in the China's oil resource, and the water-coal-slurry optimal coal product that is replace oil with coal.Water-coal-slurry has the concentration height, and fine size, characteristics such as rheology is good, long term storage does not precipitate can replace fuel oil to give full play to potential fully on heating equipments such as Industrial Boiler, chemical industry boiler, station boiler, Industrial Stoves.Water-coal-slurry also can be as the fuel oil pumping, atomizing.It successfully rises to the combustion rate of former coal 60% more than 98%, and the carbon content in the slag then drops to 0.59% of the coal slurry of heating up water by 13.7% of burning coal.Thereby demonstrated fully environmental protection, energy-conservation theme.The exploitation of water-coal-slurry simultaneously and applying makes users walk out costing an arm and a leg of fuel oil, and the shade that burns not rise reduces the operating cost of boiler, guarantee user's economic benefit, social benefit and environmental benefit.
The characteristic of water-coal-slurry: (1), efficiency of combustion height (more than 98%), pollutant emission are low.(2), has the same flowability of oil and stable.(3), can pumping, atomizing and stable ignition burning, but not spontaneous combustion.(4), the caloric value of water-coal-slurry is at 4500-4800 kilocalorie/kilogram, about two tons of water-coal-slurry can replace one ton of heavy oil.
At present in the world, the preparation of water-coal-slurry the dry method pulping process arranged, do wet method combined pulping process, high concentration ore grinding pulping process, middle concentration ore grinding pulping process, senior middle school's concentration ore grinding grating pulping process, in conjunction with pulping process of coal separation or the like.Reasons such as some pulping process is low because of the efficient of slurrying, energy consumption is high,, particle packing efficient tight to the moisture requirement of raw coal and bad adaptability are seldom used.Because the production technology of existing water-coal-slurry is uneven, is subjected to the restriction of market and investment, is difficult to form scale and benefit in a short time.
The utility model content:
The purpose of this utility model is to solve that the present technology of water-coal-slurry industry that existing middle-size and small-size water-coal-slurry user or water-coal-slurry manufacturing enterprise face exists that project investment is too high, input-output ratio imbalance and unstable product quality, can't production high-quality high-concentration coal-water slurry etc. significant deficiency or deficiency, rely on " many broken few mills ", " deposition efficiency " scheduling theory, and high efficiency, the high concentration of " in small, broken bits+pre-grinding+two stage grinding " of a kind of high efficiency, high concentration, high rheological characteristic, the water-coal-slurry device of high rheological characteristic are provided.
The purpose of this utility model is achieved in that
The water-coal-slurry device of a kind of high efficiency, high concentration, high rheological characteristic, the pre-grinding machine that comprises the fine crusher that has input port, connects with fine crusher, first slag remover of connecting with pre-grinding machine, the Pulverized Coal Bin of connecting with first slag remover, it is characterized in that: have measuring equipment in Pulverized Coal Bin, measuring equipment is connected through batcher and slurrying grinding machine, and water storage tank, dispersant storage tank and stabilizing agent storage tank are also connected through batcher and slurrying grinding machine respectively simultaneously; The slurrying grinding machine is connected through second slag remover and technology storage tank again, and the technology storage tank is connected through vertical screw pump and coal slurry grader; Pipeline of coal slurry grader and the 3rd slag remover are connected, and connect with shearing the slaking jar through the 3rd slag remover, and another pipeline of coal slurry grader is connected with atomizer mill, and through the 3rd slag remover with shear the connection of slaking jar.
Charging equipment is connected with former feed bin, and former feed bin lower part outlet place is connected with the raw coal feeding machine, and the outlet of raw coal feeding machine connects the input port of fine crusher.
The blower fan that is provided with dust-precipitator and matches at the Pulverized Coal Bin place with dust-precipitator.
The utlity model has following good effect: flow process is simple, integral layout is compact, and total installation of generating capacity is little, the production overall process can realize automation control; Invest low, the completion time of project is very short (calculates synchronously by project civil engineering and device fabrication, installation, can go into operation in 3～4 months, can up to standardly reach product in one month), can satisfy the production of multi-assortment production, to the adaptability strong (granularity, moisture, grindability index etc.) of raw coal.Can produce high-concentration coal-water slurry, can produce ultra-thin slurries again, can also realize " the bimodal grating " of water-coal-slurry particle.Deposition efficiency height (more than 74%), excellent in stability, good fluidity.
Check the relevant technologies parameter of water-coal-slurry product as follows through the production instance of this pulping process: concentration 63.5%～70%, particle mean size 30 μ m～50 μ m, ash content ACWM≤7%, dry ash free basis volatile matter Vdaf about 33%, sulphur content St, CWM≤0.47%, low heat valve Qnet 4334～4628Kcal/Kg, every index all meets GB GB/T18855---2002 " COAL-WATER SLURRY TECHNOLOGY condition " requirement.Water-coal-slurry is wanted concentration height and good fluidity, mainly realizes by rational size distribution in the coal slurry.Size particles filling mutually reduces empty gap, is that deposition efficiency improves thereby make the solid occupation rate.The technology that deposition efficiency is improved claims " grating " technology, is one of key technology of water-coal-slurry preparation.The grating of water-coal-slurry is the mill inner structure by selecting suitable pulping process, slurrying grinding machine and reasonably grind Jie's grating and realize mainly, comprises the interpolation control that mill is situated between in the running.
