The apparatus comprises a resort, a saturation tower, a cooling tower, a decoking tower and a desulfurizing tower which are communicated successively through pipelines, wherein the pipeline between the resort and the saturation tower is provided with a collecting tube which is communicated with a mud-collecting tube; the saturation tower is communicated with a sink; the mud-collecting tube and the sink are communicated with an oil-water separation pool; the oil-water separation pool is successively communicated with a measuring tank, an intermediate tank and a finished product tank; the desulfurizing tower is communicated with a heating furnace and a gas-fired boiler respectively; the heating furnace is communicated with the resort; and the saturation tower is communicated with a main air blower. The apparatus makes full use of raw materials, can be used circularly, reduces obviously production cost for enterprises and saves resource, allowing resource utilization efficiency of the oil shale to be further improved, so that the apparatus has significant economic benefits, environmental benefits and social benefits.
Description
Technical field
The present invention relates to a kind of method and device of 8mm-40mm granularity oil shale retorting oil refining.
Background technology
At resinous shale after exploitation processing, granularity only accounts for about 30% of whole output at the resinous shale of 20～125mm, because the limitation of gas retort technology, annual still have more than 100 ten thousand ton of 70% small-particle shale less than 20mm can't be used for refining oil, caused the significant wastage of oil shale resources, therefore, carrying out the following oil shale oil-refining of 20mm is a problem demanding prompt solution.
Summary of the invention
The method and the device that the purpose of this invention is to provide a kind of 8mm-40mm granularity oil shale retorting oil refining are to overcome the defective of prior art.Technical scheme of the present invention is: a kind of method and device of 8mm-40mm granularity oil shale retorting oil refining, it is characterized in that: comprise successively the gas retort by pipeline communication, saturator, cooling tower, decoking tower and thionizer, be provided with the set tank on the pipeline between described gas retort and the saturator, this set tank connected set mud tank, described saturator is communicated with wash trough, described wash trough and collection mud tank are connected with oil-water separation tank, described oil-water separation tank successively with test tank, tundish and finished pot are connected, described thionizer is connected respectively at process furnace and gas fired-boiler, and described process furnace is connected with gas retort.
Advantage of the present invention is: take full advantage of starting material, recycle methane gas, reduced significantly the production cost of enterprise, economize on resources, the oil shale resources utilising efficiency is further enhanced.Have significant economy, environmental protection and social benefit.

Embodiment
Referring to Fig. 1, the present invention relates to a kind of method and device of 8mm-40mm granularity oil shale retorting oil refining, it is characterized in that: comprise the gas retort 1 that passes through successively pipeline communication, saturator 9, cooling tower 10, decoking tower 11 and thionizer 12, be provided with set tank 2 on the pipeline between described gas retort 1 and the saturator 9, these set tank 2 connected set mud tanks 3, described saturator 9 is communicated with wash trough 4, described wash trough 4 and collection mud tank 2 are connected with oil-water separation tank 5, described oil-water separation tank 5 successively with test tank 6, tundish 7 and finished pot 8 are connected, described thionizer 12 is connected respectively at process furnace 13 and gas fired-boiler 14, and described process furnace 13 is connected with gas retort 1.
Principle of work of the present invention is as follows: through fragmentation, it is that the resinous shale of 8-40mm at first enters gas retort top ore pocket that screening obtains particle diameter, the logical thermal circulation gas gas of two-layer arch abutment is set in the gas retort, two-layer arch abutment is conducive to improve the ventilation property of oil shale layer, increase retort section height and destructive distillation time, enter in the stove by double disc intermittent type apparatus for distributing, advance the resinous shale of gas retort through the battle array umbrella, periphery from stove falls uniformly, basin by the gas retort bottom constantly rotates, by residue extraction machine semicoke is transported continuously, the resinous shale that gas retort is newly advanced on top falls slowly naturally by deadweight.The circulating mash gas gas of heat enters in the gas retort from middle part arch abutment and bottom arch abutment.
Resinous shale temperature from the process that the top retort section moves down constantly raises, the shale surface-moisture evaporates when temperature is elevated to 120 ℃, when being raised to 150 ℃-180 ℃, temperature emits the inner adsorbed gas of shale, organic pitch, shale oil and the carbonization gas of beginning in shale when temperature surpasses 180 ℃.Shale oil discharges complete substantially in the shale when shale continuation intensification reaches 500 ℃.This moment, shale became the shale semicockes of high heating value by low-temperature pyrolysis, go out and emit internal heat by the furnace bottom water logging, after the cooling wet semicoke by gas retort at the bottom of residue extraction mechanism discharge out of the furnace, concentrate through crawler belt to be transported to stockpile, transport to the contiguous Coal gangue thermo-power station of providing for oneself by automobile and carry out the coal blending burning generating.
The oil gas that oil shale distillation produces is extracted out through gas retort top battle array umbrella delivery line and is entered the set tank.Oil gas is recycled water washing in the set tank, enter saturator again and continue washing, and twice washing process gets off the oil of the part in the destructive distillation oil gas, dirt, and oil, water and the dirt in the set tank flows into collection mud tank; The You Heshui that flows down in the washing saturator enters wash trough; In oil-water separation tank, You Heshui carries out the first time to be separated; Part water after the washing saturator upper wash with enter the heat exchange of stove main air after enter in the wash trough.
Coal mine gas after the washing saturator washing is advanced the two-stage indirect cool tower and is cooled off after gas dispatch machine is discharged.Coal mine gas after cold tower cooler is processed through decoking tower and thionizer again, and coal mine gas is divided into three the tunnel: the one tunnel and goes recuperative heater to do fuel afterwards; One the road delivers to gas fired-boiler makes fuel; It is personal that the methane electrical generation unit generation is delivered on another road.
Condensate recovery system is collected the oil, water and the dirt that get off and is entered wash trough and carry out the first step and separate, the oil that separates enters collection mud tank with dirt to carry out separating the second time, entering at last oil-water separation tank separates for the third time, shale oil after settlement separate is sent into test tank by oil pump, again through tundish, after tundish are used for deposition dehydrating, check moisture, quantity, deliver to factory's finished pot by oil pump after qualified to store.
Water enters condensate recovery system and recycles after the water cooling tower cooling after separating in wash trough, the collection mud tank, and basin was used for water seal at the bottom of unnecessary water was delivered to gas retort.Water in the distillation system is all accomplished the internal recycling use, has both saved valuable water resources, has reduced simultaneously sewage discharge, protection of the environment.
