Description
Technical field:
The utility model relates to a kind of high-efficiency high-quality container moving type water-coal-slurry device that is different from the employing of traditional coal-water-slurry technology with raw coal " in small, broken bits+pre-grinding+two stage grinding " or separation coal " pre-grinding+two stage grinding ".
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 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 and exists project investment 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, a kind of high-efficiency high-quality container moving type water-coal-slurry device is provided on this basis, has proposed a kind of brand-new " in small, broken bits+pre-grinding+two stage grinding " and the high-efficiency high-quality container moving type water-coal-slurry device of " pre-grinding+two stage grinding ".
The purpose of this utility model is achieved in that
A kind of high-efficiency high-quality container moving type water-coal-slurry device, first slag remover that comprises pre-grinding machine, connects through elevator and pre-grinding machine, connect Pulverized Coal Bin with the first slag remover end opening, it is characterized in that: have burden balance in Pulverized Coal Bin, burden balance are 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; Through second slag remover and horizontal technology pump and technology agitator tank connection, through vertical technology pump and cyclone connect again by the technology agitator tank for the slurrying grinding machine; Pipeline of cyclone and the 3rd slag remover are connected, and through the 3rd slag remover and the connection of shearing slaking jar, another of cyclone pipeline is connected with shearing the shaping mill, and connects with shearing the slaking jar through the 3rd slag remover, and above-mentioned each equipment constitutes whole production line and is installed on the vehicle frame dish.
Charging equipment is connected with run coal bin, and the lower part outlet of run coal bin connects the raw coal feeding machine, and the raw coal feeding machine is connected with efficient pre-grinding machine.
Have additional dust-precipitator and supporting with it dust collecting fan on Pulverized Coal Bin, the fine powder of withdrawal is then directly into Pulverized Coal Bin, and this section is promptly finished raw material processing.
The utlity model has following good effect: flow process is simple, integral layout is compact, total installation of generating capacity is little, investment is low, the completion time of project very short (can go into operation in 3～7 days), 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.When being installed on whole production line on the vehicle frame dish, can realize portable production, be very favourable for manufacturing enterprise's service equipment with making things convenient for some small-sized water-coal-slurry users.
