Description
Technical field
The utility model relates to oil shale resources comprehensive utilization technique field, is a kind of resinous shale drying, heating, oil refining, coal-char combustion integrated apparatus.This integrated apparatus also can be used for coal, oil-sand, junked tire, refinery coke, organic waste materials and biomass.
Background technology
Resinous shale is a kind of important Energy resources.The resinous shale mineral deposit has all been found in different continents, and its quantity has surpassed 600 resinous shale basins.Worldwide, oil shale reserves is converted into thermal value and is only second to coal and is at the second place; Being converted to shale oil and being equivalent to 4,750 hundred million tons, be 5.4 times of the natural oil workable reserve, is the desirable substitute energy of current oil, coal, Sweet natural gas.Approximately 2,000,000,000,000 tons of oil shale in China Prospective resources, 80,000,000,000 tons of folding shale oil, be 32 times of 2,500,000,000 tons of oil residual recoverable reserves, occupies the 4th, the world.315.67 hundred million tons of the reserves of verifying in 1989, in nearest new round of resources evaluation, China confirms 7,199 hundred million tons of total resourcess, 47,600,000,000 tons of folding shale oil.
Resinous shale is a kind of organic matter that is rich in, and has fine bedding, the pulveryte that can burn.The overwhelming majority organic in resinous shale is the one-tenth oil substances that is insoluble to ordinary organic solvents, is commonly called as oil female.Therefore, resinous shale claims again oil shale.
As a kind of Energy resources, resinous shale develops main technological route, the one, destructive distillation oil refining, the 2nd, direct combustion power generation.Oil shale retorting oil refining belongs to the low-temperature pyrolysis technology, in the situation that heating resinous shale rear pyrolysis in gas retort, isolated air or oxygen produces shale oil and fuel gas, and shale oil can directly be used as oil fuel, but also precision work is the liquid fuels such as gasoline, diesel oil.The Heating temperature general control is in 450～550 ℃ of scopes.
Existing oil shale distillation technology is mainly gaseous heat-carrier retorting technique and solid thermal carriers retorting technique.The gaseous heat-carrier retorting technique be in gas retort by the macrobead resinous shale of 15～75mm by with the heating gas direct contact heat transfer, realizing low-temperature pyrolysis.Must additionally supplement the gases such as coal gas when the coal gas amount of oil shale distillation generation is inadequate.This technology major advantage is for saving the comminution energy conssumption of resinous shale.Existing deficiency is: 1) due to the macrobead resinous shale that is destructive distillation 15～75mm, making in mining or shattering process the following short grained resinous shale of 15mm not send in gas retort is utilized, this part shale amount accounts for 20%～25% of gross recovery, so the wasting of resources is huge; 2) heating gas of gaseous heat-carrier need to be heated to 700～800 ℃, and this need to consume part coal gas or other fuel; 3) due to what adopt, be the macrobead resinous shale, the destructive distillation time is quite long, generally needs 12～24 hours, and there is evil mind in macrobead inside usually, causes that dry distillation efficiency is low, oil yield is low, utilization ratio is low; 4) the semicoke heat after destructive distillation accounts for 35～45% of resinous shale heat, and energy dissipation is large, and the semicoke after destructive distillation can not directly be made material of construction, the further calcination process of needs; 5), if the semicoke after destructive distillation continues as the boiler oil utilization, first cooling rear fragmentation is to be applicable to the requirement of boiler oil particle, if wet method must first be used water cooling except semicoke, drier, more broken, therefore, consume energy larger; 6) need to realize low-temperature pyrolysis with macrobead resinous shale direct contact heat transfer because of gaseous heat-carrier coal gas, cause by gas retort oil and gas content out to strengthen, subsequent condensation equipment not only volume increases, and arranges also relative complex.
The solid thermal carriers retorting technique be in gas retort by the granule wax shale below 25mm or below 15mm or below 8mm or below 6mm by with the grey direct contact heat transfer of solid carrier heat, realizing low-temperature pyrolysis.Existing solid thermal carriers destructive distillation mainly adopts horizontal circle tubular gas retort, and the source of solid thermal carriers is that the coal-char combustion that gas retort generates produces, or sets up separately gas-fired process furnace heating porcelain ball etc. as thermal barrier.Solid thermal carriers and gaseous heat-carrier relatively, because the oil shale particle degree required is little, and with the solid thermal carriers good mixing, therefore, the destructive distillation time is short, in common 30 minutes, can complete, the shale utilization ratio of exploitation can reach 100%, and oil yield is high, the Energy resources less wastage.
Although the method is mainly for the treatment of short grained resinous shale, but its main drawback is to need extra solid particulate process furnace, device is complicated huge, serious wear, short, the remaining semicoke of continuous operating time and lime-ash are abandoned in a large number, capacity usage ratio is low, and because roasting kiln just is used to provide the heat ash of solid thermal carriers, so can not realize the purpose (Galator technology) of generating.Open (bulletin) CN101117584 of Chinese invention patent application discloses the applicant, denomination of invention is: " oil shale retorting oil refining, coal-char combustion power generation integrated technique ", it can be realized in oil shale retorting oil refining, the semicoke generating of burning destructive distillation, due to the residing conceptual phase of this technique from now different, do not consider at that time the flue gas drying wet oil shale that utilizes circular fluid bed to produce, do not consider that the hot lime-ash of circulating fluidized bed boiler bottom part sends in destructive distillation and the shale HYBRID RETORTING as solid thermal carriers simultaneously yet, so, this technique has limitation, not yet realize the maximization of resinous shale comprehensive utilization.
