Abstract
The invention discloses a method for power generation and for making cement clinker with oil shale residue and flue gas, wherein, oil shale is fed into the an oil shale separator for heating and dry distillation to produce shale oil-gas, then shale oil, flue gas and oil shale residue can be obtained through treatment in a shale oil condenser. The oil shale residue and cement addictive can be crushed and mixed with flue gas prior to injecting into the combustion chamber of furnace, and then thermal energy can be generated through combustion to drive the generating unit for generating purpose. The shale slag following the combustion can be used as cement clinker directly. The invention employs directly the flue gas and shale oil residue generated in the process of dry distillation as the solid and gas flue to achieve thermal generation and cement clinker, thereby allowing comprehensive utilization of oil shale, avoiding environmental pollution and land consumption, which is suitable for shale oil extracting, cement clinker making and power generating application.
Description
Technical field
The present invention proposes is utilizing oil shale waste and combustible gas generating and producing the method for cement clinker of the energy and building materials field.
Background technology
Before patent of the present invention proposed, the shale slag air storage behind the resinous shale extraction shale oil not only land occupation also can influence surrounding enviroment.Utilize that it makes that cement clinker also needs to transport, feed proportioning and calcining, economy is bad, causes the cost height, has influenced its use.
In the process of carrying oil, also produce a large amount of combustible gases, can't directly utilize, can not directly discharge again, cause the waste of the energy and the pollution of environment.
Summary of the invention
In order to utilize shale slag generating calcination of cement clinker simultaneously, the present invention proposes the method for utilizing oil shale waste and combustible gas generating and producing cement clinker.This method will be by carrying oil shale waste behind the oil and pulverize the back and put forward combustible gas in the oily process obtains electric power and cement clinker simultaneously in the stove internal combustion as the thermal source of generating technical problem.
The scheme that technical solution problem of the present invention is taked is: resinous shale joins and heats destructive distillation in the oil shale distillation oil extraction plant, resinous shale is subjected to the volatilization of Temperature Influence organic volatile and forms shale oil gas, shale oil gas obtains shale oil by the shale oil condenser condenses, and combustible gas is told from condenser.From destructive distillation device, take out the shale slag after the destructive distillation, shale slag and cement additire are crushed into powder and combustible gas through pulverizer and are mixed into shale slag and combustible gas mixed flow and are injected in the combustion chamber of the fluidizing furnace that generates electricity and burn, the evolution of heat, heating furnace body makes water form steam, the generating of pushing generator group.The shale slag is fully burned in the combustion chamber, makes solid carbon content be reduced to the degree that the cement clinker technical requirements allows and makes it produce activity directly as cement clinker.The fluidizing furnace flue gas enters atmosphere through handling.
Because the present invention directly obtains heat and cement clinker as solid and gas fuel combustion with combustible gas and the oil shale waste that the oil shale distillation process is produced, utilize the heat generating that is produced, realized that the whole of resinous shale raw material make full use of, stop oil shale residues, waste gas and boiling furnace combustion fuel waste residue to the pollution of environment with to appropriation of land, obtained dual economic benefit and social benefit and environmental benefit.The suitable resinous shale that utilizes simultaneously of the inventive method is put forward oil and calcining cement clinker and power generation applications.

Embodiment
According to shown in Figure 1, resinous shale joins in the oil shale distillation oil extraction plant 1 and heats destructive distillation, resinous shale is subjected to the volatilization of Temperature Influence organic volatile and forms shale oil gas 2, and shale oil gas obtains shale oil 4 by 3 condensations of shale oil condenser, and combustible gas 5 is told from condenser.From destructive distillation device, take out shale slag 6 after the destructive distillation, shale slag and cement additire 8 is crushed into powder and combustible gas through pulverizers 7 and is mixed into shale slag and combustible gas mixed flow 9 and is injected to the evolution of heat of burning in the combustion chamber 10 of the fluidizing furnace 11 that generates electricity, heating furnace body makes water form steam, 13 generatings of pushing generator group.The shale slag is fully burned in the combustion chamber, makes solid carbon content be reduced to the degree that the cement clinker technical requirements allows and makes it produce activity directly as cement clinker.Fluidizing furnace flue gas 12 enters atmosphere through handling.
Cement additire comprises active reinforcing agent, smoke prevention and dust control agent, fusing point depressant and cement composition supplement.Wherein active reinforcing agent can be Aluminosilicates; The smoke prevention and dust control agent can be oxysalt; The fusing point depressant can be calcium, sodium matter alkaline metal salt; The cement composition supplement can be replenished necessary mineralogical composition according to the physical and chemical composition of shale slag ash, for example increase its early strength and need add gypsum.
The component of the cement additire that is added according to the different places of production and quality and moiety decision is to reach the cement physicochemical property effect of best type.
The inventive method in the oil shale retorting oil extraction plant, extract simultaneously obtain shale oil, can Combustion gas and shale slag; Directly utilize combustible gas and shale slag as the thermal source fuel of generating, logical Cross the generating of boiling furnace combustion generation Steam Actuation generator and obtain electric energy; Be added with cement adding Resulting shale slag ash can be directly as clinker after the shale slag burning of agent. Fully Utilized the organic principle in the oil shale to be converted into utility and the energy that can directly utilize Amount takes full advantage of again the mineral matter resource in the oil shale and has reduced shale slag and flyash Environmental emission, have the technique effect of obvious energy-saving and environmental protection.
