The invention have the advantage that and take full advantage of raw material, recycle methane gas, it will be apparent that reduce the production cost of enterprise, economize on resources, make oil shale resources utilization ratio be further enhanced.There is significant economy, environmental protection and social benefit.
Accompanying drawing explanation
Fig. 1 is the agent structure schematic diagram of the present invention.
Detailed description of the invention
See Fig. 1, the present invention relates to the method and device of a kind of 8mm 20mm granularity oil shale retorting oil refining, it is characterized in that: include passing sequentially through the gas retort 1 of pipeline communication, saturator 9, cooling tower 10, decoking tower 11 and desulfurizing tower 12, set tank 2 it is provided with on pipeline between described gas retort 1 and saturator 9, this set tank 2 connected set mud tank 3, described saturator 9 connects kitchen sink 4, described kitchen sink 4 is connected with oil-water separation tank 5 with collection mud tank 2, described oil-water separation tank 5 successively with measuring tank 6, pans 7 are connected with finished pot 8, described desulfurizing tower 12 is connected with gas fired-boiler 14 respectively at heating furnace 13, described heating furnace 13 is connected with gas retort 1.
The operation principle of the present invention is as follows: through broken, screening obtains the oil shale that particle diameter is 8-20mm and initially enters gas retort top ore pocket, two-layer arch abutment is set in gas retort and leads to thermal circulation gas gas, two-layer arch abutment is conducive to improving the breathability of oil shale layer, increase retort section height and retorting time, enter in stove by double disc batch (-type) apparatus for distributing, enter the oil shale of gas retort through battle array umbrella, uniform periphery from stove falls, constantly rotated by the basin of gas retort bottom, by slag extractor, semicoke is transported continuously, top is newly entered the oil shale of gas retort and is the most naturally fallen by deadweight.The circulating mash gas gas of heat enters in gas retort from middle part arch abutment and bottom arch abutment.
Oil shale temperature during top retort section moves down constantly raises, when temperature is increased to 120 DEG C, shale surface moisture evaporates, release the internal adsorbed gas of shale when temperature is raised to 150 DEG C-180 DEG C, when temperature is more than 180 DEG C, in shale, organic matter starts Colophonium, shale oil and carbonization gas.When shale continuation intensification reaches 500 DEG C, in shale, shale oil discharges complete substantially.Now shale becomes the shale semicockes of high heating value by low temperature distillation, gone out by furnace bottom water logging and release internal heat, after cooling, wet semicoke is discharged out of the furnace by residue extraction mechanism at the bottom of gas retort, concentrates through crawler belt and is transported to stockpile, automobile transports to neighbouring Coal gangue thermo-power station of providing for oneself and carry out coal blending burning generating.
The oil gas that oil shale retorting produces is extracted out through gas retort top battle array umbrella delivery line and is entered set tank.Oil gas is washed by recirculated water in set tank, enters back into saturator and continues washing, and the part oil in dry distilling oil gas, dirt are got off by twice washing process, and oil, water and the dirt in set tank flows into collection mud tank；The oil flowed down in washing saturator and water enter kitchen sink；In oil-water separation tank, You Heshui carries out separating for the first time；Part water after washing saturator upper wash enters in kitchen sink after entering stove main air heat exchange.
Device in Gas after the washing of scrubbed saturator, after gas dispatch machine is discharged, is entered two-stage indirect cool tower and is cooled down.Device in Gas after cold tower cooler processes through decoking tower and desulfurizing tower again, and device in Gas is divided into three tunnels afterwards: a road goes recuperative heater to do fuel；One road is delivered to gas fired-boiler and is made fuel；Another road is delivered to gas electricity unit generation and is used by oneself.
Oil, water and dirt entrance kitchen sink that condensate recovery system is collected carry out the first step and separate, the oil separated and dirt enter collection mud tank to carry out separating for the second time, finally enter oil-water separation tank to carry out separating for the third time, shale oil after settlement separate sends into measuring tank by oil pump, again through pans, pans after the deposition dehydrating, check moisture, quantity, qualified after delivered to factory's finished pot by fuel circulating pump and store.
After separating in kitchen sink, collection mud tank, water is after cooling tower cools down, and enters condensate recovery system and recycles, and unnecessary water delivers to gas retort bottom water basin for water seal.Water in distillation system all accomplishes that inner loop uses, and has both saved the water resource of preciousness, decreases sewage discharge simultaneously, protects environment.
