Description
The present invention relates to a kind of new forms of energy, fresh fuel and manufacturing technology thereof of synthetic, particularly a kind of high viscous crude system oil-water-coal slurry and technology thereof.
High viscous crude is the very big natural energy source of a kind of resource, because its composition is special, be not suitable for resembling and refine various lightweight oil plants and petrochemicals other the crude oil, under the prerequisite of market economy, its best economic outlook is to convert electric energy and heat energy as fuel to by burning.Owing to high viscous crude zero pour height, viscosity is big, and rheological is poor, can not directly burn as fuel, though simple the processing can be used for burning reluctantly, be directed at that waste is big, thermo-efficiency is low because burn-off rate is low, and can tie charcoal and smolder and discharge various objectionable impurities contaminate environment.Coal is the known natural energy source of people especially, and people come direct incendiary to coal as a kind of natural fuel without any processing for a long time, and its consequence is not only wasted greatly.Thermo-efficiency is low, and the problem atmosphere that has been the serious pollution of the flue dust that discharged has destroyed physical environment, this severity of harm humans survival and development has been arrived in atmospheric pollution and environment damage, demands urgently fundamentally solving.
The purpose of this invention is to provide a kind ofly by synthetic, exist with the form of slurry, burn in the mode of mist, heat is big, efficient is high, and save energy does not discharge harmful flue dust, oil-water-coal slurry fuel free from environmental pollution.
Another purpose of the present invention provides a kind of method of producing oil-water-coal slurry.
Above-mentioned purpose of the present invention adopts following technical proposals to realize, that is:
Oil-water-coal slurry fuel is to be mixed with by the oil of 20-30%, the water of 7-30%, the coal dust of 40-70%, the oil-in-water type tensio-active agent of 1-2%, the decentralized tensio-active agent of 1-5 ‰ and the stablizer of 1-5 ‰.
The oil-in-water type tensio-active agent can adopt fatty acid loss water sorbit ester, polyvinyl chloride ether etc.
The decentralized tensio-active agent can adopt the hydrocarbonylation acid waste liquid.
Stablizer can adopt polyacrylamide flocculant, carboxymethyl cellulose etc.
Embodiment one
Oil-water-coal slurry fuel is to be mixed with by 30% viscous crude, 28% water, 39% coal dust, 2% lipid acid anhydrous sorbitol fat, 5 ‰ hydrocarbonylation acid waste liquid, 5 ‰ carboxymethyl celluloses.
Embodiment two
Oil-water-coal slurry fuel is to be mixed with by-35# diesel oil 40%, 10% water, 48% coal dust, 1% polyvinyl chloride ether, 5 ‰ hydrocarbonylation acid waste liquid, 5 ‰ polyacrylamide flocculants.
The production method of oil-water-coal slurry fuel:
The manufacturing process of oil-water-coal slurry of the present invention is such: at first the feed coal for preparing is become particle below 10 millimeters (if the granularity of feed coal is that face coal below 10 millimeters or coal slime are just without this procedure) with artificial or crusher in crushing, then that fragmentation is good coal is put into coal pulverizer and is added a certain amount of water simultaneously and carries out wet-milling and become coal dust, and the fineness of coal dust will reach 80%-90% by 200 eye mesh screens.Grind qualified band water and coal dust through coal pulverizer and send floatation device to and carry out floatation purification this afterwards, remove the ash content and the sulphur content of the overwhelming majority in the coal dust by floatation purification.Coal dust through floatation purification will filter it by strainer, gets rid of underproof coal grain and other impurity by filtering.Afterwards coal dust is carried out processed, the coal dust after processed will be made the coal dust cake of relatively dry with standby.What more than say is processing treatment process to feed coal, and what say below is processing treatment process to high viscous crude, because high viscous crude be at normal temperatures for colloidal can not flow, so adds at first will heat to it man-hour it is dissolved.The temperature of high viscous crude should remain on about 80-90 ℃ after heating, afterwards temperature is poured in the oil at a certain amount of hot water of 80-90 ℃, and simultaneously a certain amount of oil-in-water type tensio-active agent is added wherein, make water and oily emulsification hand over the slurries of melt into water-in-oil-type through stirring.Stir in the slurries that a certain amount of coal dust cake that will prepare after this and a certain amount of decentralized tensio-active agent are added to this water-in-oil-type, make water, oil, these three kinds of materials of coal hand over the preliminary oil-water-coal slurry of melt into mutually by stirring.Again this preliminary oil-water-coal slurry is delivered to afterwards in the ultrasonic wave refinement diverting device and also will be added a certain amount of chemical stabilizer simultaneously, starting recycle pump allows preliminary oil-water-coal slurry circulate fast repeatedly in this device, this flowing generally will have 3 to 4 circulations to get final product, by this circulate fast repeatedly allow preliminary oil-water-coal slurry repeatedly accept certain frequency, the ultrasonic irradiation of certain intensity, make the globule by ultrasonic irradiation, oil droplet, the particle of coal is thinner more equal, makes water, oil, coal is handed over more uniformly and is dissolved in together and makes water under the effect of chemical stabilizer, oil, coal does not break away from quite long period mutually.So far this new forms of energy of the oil-water-coal slurry of appellation of the present invention, fresh fuel have just been manufactured.Qualified oil-water-coal slurry product can store with hold-up vessel and plastics bag can carton case packing, then according to the needs of user and Bu field respectively by underground pipeline, special-purpose tank car and general various vehicles drive to the user use there with market on sell.
This pulpous state fuel of oil-water-coal slurry, has the same flowability of water, the inflammableness that oil is the same, its burn-off rate, thermo-efficiency are greater than coal and oil, can replace various coals and oil fuel for power station, Industrial Boiler fully, Industrial Stoves, civilian all size heating boiler, water heater, tea furnace etc. use.Oil-water-coal slurry is compared not only with coal fuel, and its thermal value, burn-off rate, thermo-efficiency are far longer than coal fuel, the more important thing is that oil-water-coal slurry has fundamentally overcome coal fuel discharges flue dust, contaminate environment in atmosphere when burning hazardness, also overcome coal fuel in transportation, load and unload, deposit, shortcoming such as link is many when using, occupation of land is many, waste is many, equipment amount is big, labour intensity is big, and expense is big.Oil-water-coal slurry is compared with oil fuel, not only can be carried out spray burning by nozzle as oil firing fully; and than the burn-off rate of oil fuel; the thermo-efficiency height; just be lower than oil fuel especially from far away as for price; so not only saved a large amount of oils energy, protected environment, also can make industries such as generating, heat supply economic benefit is significantly improved simultaneously by reducing fuel cost.
Can keep the rare matter oil plant of mobile at normal temperatures, when making the water-in-oil slurries, oil and water can be heated, and certain water gaging are directly poured into to stir in a certain amount of oil get final product.
Accompanying drawing one is the process flow sheet of feed coal processing link of the present invention.
Accompanying drawing two is process flow sheets of high viscous crude processing link of the present invention.
Accompanying drawing three is product synthesis process flow diagrams of the present invention.
What fuel had on external form is solid-state, as coal.What have is liquid as oil.What have is gaseous state, as Sweet natural gas.Though the external morphology of fuel is different, but the material property of various fuel all is the same with the intrinsic chemical ingredients, be that various fuel all are the polymer hydro carbons materials that belongs to complicated, all form by C (carbon), H (hydrogen), O (oxygen), N (nitrogen), S (sulphur), A (ash content), W chemical ingredientss such as (moisture).Have same material property, same chemical ingredients, be used for various fuel of incendiary such as coal and wet goods equally again and handle, external morphology by changing them, keep and develop their strong points separately through remarkable science and technology, abandon and overcome their weakness separately, and the complementarity of utilizing them to exist is mutually come the more reasonably ratio of combusting component of artificial arrangement, be fully can be from new synthetic a kind of new forms of energy that more help human survival and development need, fresh fuel.The present invention considers again that according to above-mentioned mechanism organic oils liquid fuel, organic coal class solid fuel and water are (from the chemical ingredients H of water
2Can burn; O can say on combustion-supporting this meaning; water also is a kind of fuel) be storage capacity maximum on the earth, the easiest obtain, use the most general, also maximum to the influence of save energy and environment protection, therefore selected water, oil, these several energy substances of coal starting material as oil-water-coal slurry of the present invention.Comprehensive condition from all respects such as safety, storage, transportation, energy-saving and environmental protection, burning, expenses, the external morphology of fuel is that flowable liquid form is the most desirable, and the external morphology of fuel is for can not the mobile solid form being the most worthless, so the external morphology of oil-water-coal slurry of the present invention is designed to flowable liquid pulpous state form.From making things convenient for burning, burn-off rate, heat release efficient, energy conservation, environment protection; aspects such as labour intensity are considered; it is the most desirable being vaporific burning by nozzle by fuel; the combustion system of high-grade combustion system, so oil-water-coal slurry of the present invention the most is designed to carry out with nozzle the mode of spray burning.In order to realize that oil-water-coal slurry of the present invention can exist with the form of slurry, mode with mist is burnt, at first will can not carry out artificial change by the solid-state external morphology of the fast shape of mobile to feed coal is the sort of, the process of this change is exactly by a series of mechanical means, requires the process that feed coal is carried out a series of processing according to certain quality.Accompanying drawing one is the process flow sheet that feed coal is carried out a series of processing, according to the coal that this process flow sheet machines, can reach the processing quality requirement of oil-water-coal slurry of the present invention to coal fully.This process flow sheet has designed six procedures and has guaranteed processing to coal, because feed coal all is some irregulars basically, and the block brittle solid that differs in size, therefore first procedure is designed to the fragmentation to feed coal.Because coal is a kind of crumbly mass, therefore just can easily irregular feed coal be broken into the particle below 10 millimeters of comparison rule with artificial and crusher.Why require first procedure feed coal will be broken into particle below 10 millimeters, this mainly is to carry out the desired regular particle size of works better for the coal-grinding function that guarantees second operation work.This technology second operation work is first procedure to be processed the coal grain below 10 millimeters that gets off by coal pulverizer, grinding into fineness after adding a certain amount of water is the coal dust that 80%-90% passes through 200 eye mesh screens, at the such coal dust of microscopically is the combination of countless thin buckwheat coals, the diameter dimension of average 75% coal particle is below 50 microns, and maximum particle diameter size also is no more than 200 microns.Why feed coal will be ground so regular so combustion powder of fineness, one of reason is the flame mechanism of making every effort to meet more fuel.Prove that through scientific experiment the process of fuel combustion promptly is that the combustible element of fuel such as carbon (C), hydrogen (H) etc. and airborne oxygen carry out violent chemical combination, emit the chemical reaction process of a large amount of heat energy under quite high temperature.Therefore under the constant prerequisite of unit mass, by a bulk of coal being become thousands of even tens thousand of relatively independent tiny coal particles, this has just increased the outer surface area of the coal of certain mass greatly, outer surface area has increased, the contact surface of air and coal has also just increased so, will make the chemical combination degree of fuel and airborne oxygen more violent like this, more thorough, the burn-off rate of the combustible element in the fuel will improve greatly as a result, the burn-off rate of fuel has improved, liberated heat has also just improved, liberated heat has improved, the thermo-efficiency of fuel has also just fundamentally improved, and the thermo-efficiency that improves fuel is fuel economy, i.e. the basic place of save energy.In second operation work, why to grind into the fineness that 80%-90% passes through 200 eye mesh screens to coal, the particle that also is coal except above-mentioned first reason is thin more more little, the weight of himself will be light more, so just can make in the particle suspension Yu Shui and oil of coal, reaching can be with flow purpose with spray burning of water and oil, promptly reach oil-water-coal slurry of the present invention and exist, with the mode incendiary purpose of mist with the form of starching.Entering three process through the qualified coal dust of wet-milling is 3 floatation purification operations in the accompanying drawing one, and the purpose of this procedure is that the ash content (A) and the sulphur (S) of the overwhelming majority in the feed coal are removed.The ash content (A) of 50%-75% and the sulphur (S) of 40%-90% are removed in the coal dust of scientific experiment proof 80-90% by 200 eye mesh screens can be with feed coal behind floatation purification, will realize that like this oil-water-coal slurry of the present invention significantly reduces the purpose to atmosphere and environmental pollution when burning.It is 4 filtration operation in the accompanying drawing one that coal dust behind floatation purification enters next process, and the purpose of this operation is bring the foreign material of difficulty to remove by filter possible for some coal grains that require greater than fineness of pulverized coal and some storing and burning.Coal dust after filtering enters next process, i.e. 5 these procedures of dehydration in the accompanying drawing one, and purpose is that redundant moisture in the coal dust is got rid of, and generally just can be easy to unnecessary water eliminating with the vacuum concentration strainer.Coal dust after processed enters next process, i.e. 6 these procedures of system coal dust cake in the accompanying drawing one, by this procedure with coal dust make water content suitably and the pie coal dust of cleaning with standby.So far feed coal has been enough to satisfy manufacturing oil-water-coal slurry of the present invention to the specification of quality of coal through a series of processing.
Accompanying drawing two is the processing process figure to high viscous crude, because the zero pour height of high viscous crude, therefore be the solid shape of colloid at normal temperatures, be to be difficult to it is carried out process and remould under these circumstances, therefore 7 these procedures have designed high viscous crude have been heated in the accompanying drawing two, its objective is to make by heating to dissolve into liquid.Oil temperature after the heating should remain on about 80 ℃, oily complete liquid state in a flowable at this moment.If according to user's needs with the stock oil of lightweight oils such as diesel oil kerosene, just needs do not heat this procedure to oil.Enter next process afterwards, i.e. 8 Jia Shui and add this procedure of oil-in-water type tensio-active agent in the accompanying drawing two, wherein the temperature of added water should be between 80-90 ℃, added oil-in-water type tensio-active agent, its parent hates the equilibrium value (HLB) should be between 2-6.Why will add a certain amount of water in oil, one of reason is because the molecular structure of high viscous crude is too tight, viscosity is big, the burn-off rate of combustible element when needed rheological was with burning when this situation was unfavorable for burning very much.Therefore obtain loose, viscosity and obtain decline by in oil, adding molecular structure that this natural dispersion agent of a certain amount of water just can make oil.A certain amount of water and under the effect of tensio-active agent can make oil form water in oil form.Oil droplet is heated in combustion processes, temperature constantly rises, because the boiling point of oil is than the boiling point height of water, water will be vaporized prior to oil like this, continuous rising along with temperature, the expansion that this water of having vaporized is will be in oil droplet rapid, can break through encirclement and the constraint of oil film with the form of microexplosion at last to it, the result just splits into many thinner littler oil droplets to an oil droplet, will improve the fuel atomizing fineness like this and then efficiency of combustion is improved, especially various oil droplets is uninterrupted microexplosion in the combustion chamber, splash, can improve the turbulivity of combustion zone, the combustion processes that this extremely helps further strengthening oil-water-coal slurry of the present invention makes this fuel of oil-water-coal slurry of the present invention easily by thorough after-flame.Oil-water-coal slurry of the present invention reduces by this after-flame completely just and eliminates the generation of carbon black and outwards discharging.Because the existence of steam in this fuel of oil-water-coal slurry of the present invention can cause the decline of flame temperature, will suppress objectionable impurities nitrogen oxygen (NO so in addition
x) change the generation of thing and outwards discharging.Prove that through scientific experiment add 20% water in oil, this not only helps improving efficiency of combustion, suppresses smoking of the exhaust effectively, can also realize fuel-economizing about 12%; Reducing the carbon black discharging puts about 70-80%; Reduce nitrogen oxygen (NO
x) change thing quantity discharged about 70%.This is very important very favourable to save energy, protection atmosphere, protection environment.In accompanying drawing 28 these procedures, not only in oil, add a certain amount of water, and when adding water, also to add a certain amount of oil-in-water type tensio-active agent, as fatty acid loss water sorbit ester, Soxylat A 25-7 etc., this is because water and oily as two kinds of different materials, they are immiscible under general situation, if but among them, add certain amount of surfactant and stir by certain device, so just can make moisture be cleaved into various trickle droplets and be suspended in uniformly in the oil, make water and oil form the stabilized uniform water-in-oil type emulsion.
Accompanying drawing three is oil-water-coal slurry product synthesis process flow diagrams of the present invention.This procedure of this flow process Figure 10 is by stirrer a certain amount of water-in-oil-type slurries that the coal dust cake of a certain amount of accompanying drawing one coal processing link generation, accompanying drawing two oily processing links produce to be mixed together.In order to make among coal particle energy even and stable the dispersion suspension Yu Shui and oil, also to add a certain amount of decentralized tensio-active agent during stirring.Its effect is after the decentralized tensio-active agent is adsorbed to each coal particle surface, can form very thin one deck active agent molecule and water oiling film on the surface of each coal particle, so just can reduce the interfacial tension between coal particle and water and the oil greatly, hinder between each coal particle possible coalescent, and then play and reduce the internal friction of oil-water-coal slurry when flowing, reduce viscosity, make coal particle can be in water and oil dispersed uniform and stable effect.Processing by accompanying drawing 3 10 these procedures, at this moment water, oil, coal have been stirred and have been mixed into preliminary oil-water-coal slurry, enter next process then, be these procedures of accompanying drawing 3 11 ultrasonication, at first in preliminary oil-water-coal slurry, add a certain amount of chemical stabilizer in this procedure, as polyacrylamide flocculant, carboxymethyl cellulose etc.Because these chemical stabilizers have make in the oil-water-coal slurry dispersive coal particle can with other coal particle around it and around water and oil be combined into a kind of more weak but the three-dimensional empty isostructural effect of certain intensity is arranged, thereby stop the precipitation of coal particle effectively and prevent coal and water and oil separating.Can start recycle pump after adding chemical stabilizer, allow preliminary oil-water-coal slurry carry out several flowing fast repeatedly in the ultrasonic wave refinement diverting device of ultrasonic equipment being equipped with, make preliminary oil-water-coal slurry blended more evenly and accept certain frequency, the ultrasonic irradiation of certain intensity by flowing.Because ultrasonic wave has trickle and the intensive porphyrization, therefore big relatively coal particle, the globule and oil droplet can be pulverized even more and fine and smooth in the preliminary oil-water-coal slurry, again because ultrasonic wave has the inaccessible dissemination of other method, therefore can be the water in the preliminary oil-water-coal slurry, oil, dispersive such as coal and tensio-active agent and chemical stabilizer are more even, more stable.So far preliminary oil-water-coal slurry just has been processed to the final product of the oil-water-coal slurry of the present invention of accompanying drawing 3 12 after having passed through accompanying drawing 3 11 ultrasonication.The final product of oil-water-coal slurry can promptly produce promptly and use, also can be according to accompanying drawing 3 13 these procedures hold-up vessel and plastics bag cans, and the carton case packing stores in order to allocation and transportation.
The starting material of oil-water-coal slurry of the present invention are except water, and the kind of stock oil and the kind of feed coal can be selected and allocate according to user's practical situation and actual needs.As suburb in the city and the also unnumbered numerous small users of vast rural area number, just can be according to their scattered dispersion, multi-point and wide-ranging, characteristics that combustion equipment does not generally possess heating unit, adopt light-weight diesel oil, kerosene etc. are stock oil, in winter of cold for the numerous small users that are mainly used in winter heating for antifreeze, stock oil can adopt negative sign diesel oil.Will satisfy this class user's needs so easily.Though the oil-water-coal slurry of Chu Liing has consumed a certain amount of lightweight oil plant like this; but see it also is very suitable, very necessary from social benefit, environment protection angle; because the also unnumbered numerous small users of these numbers cause topsoil just because of coal-fired flue dust and the objectionable impurities that discharges; the important source of pollution of environmental degradation; and be the most scabrous source of pollution; therefore the present invention adopts the lightweight oil plant to aim at oil-water-coal slurry that these small users manufacture at the protection atmosphere, has the particularly important meaning on the protection environment.Because the lightweight oil plant is hydrogeneous higher, so just can utilize hydrogeneous less hard coal or low grade coal to be feed coal in addition, make between them to make up for each other's deficiencies and learn from each other, so just make hard coal, the low grade coal that resource is big, price is honest and clean that the ample scope for abilities has been arranged.Though the starting material of oil-water-coal slurry of the present invention are defined as water, oil, three kinds of materials of coal from total aspect in a word, in particular case, the kind of oil and the kind of coal can change flexibly in face of the particular user.
Oil-water-coal slurry of the present invention is as a kind of New-type fuel of synthetic, and its quality guaranteed period was designed to about 100 days, and promptly the final product of oil-water-coal slurry the longlyest can not surpass 100 days from the incendiary shelf lives of dispatching from the factory, otherwise water, oil, the isolating situation of coal may occur.
This new forms of energy of oil-water-coal slurry of the present invention, the high-order calorific value of new right material is by the intrinsic calorific value decision of concrete stock oil that adopts and feed coal, and its high-order calorific value is lower than oil fuel in general, is higher than coal fuel; Its low heat value not only is higher than the low heat value of coal fuel far away, unlike the low heat value difference of oil fuel what.
