Description
Technical field
The present invention relates to a kind of resinous shale technical field of comprehensive utilization, the de-technique except lightweight oil and device before being specifically related to oil shale oil-refining emission power generation.
Background technology
The coal mine gas that dry distillation apparatus for oil shale produces does the obtained raw gas of vaporized chemical with the gas mixture of air and water vapour, containing various impurity. Use to coal gas is brought serious harm by existing of these impurity, it is necessary to by removals totally, power generation needs could be met. So tail gas must carry out preprocessing process before generating, the impurity such as hydrogen sulfide, tar in coal mine gas can be removed by pre-treatment. Much the detar device of oil shale oil-refining surplus gas generating enterprise routine adopts electrical tar precipitator at present, and the coal tar removal effect that electrical tar precipitator produces for coking of coal industry is very good. But not only containing mink cell focus in the tail gas that dry distillation apparatus for oil shale produces, also containing a certain amount of lightweight oil. These lightweight oils exist with the form of gas molecule, cannot change into liquid molecule at normal temperatures and pressures. Electrical tar precipitator cannot lightweight oil in effective elimination coal mine gas. In coal mine gas, the existence of lightweight oil causes sweetening agent in follow-up sulfur removal technology poisoning, and sweetening effectiveness is deteriorated, and the thionizer cycle of operation shortens, and desulfuration efficiency reduces.
Summary of the invention
It is an object of the invention to solve electrical tar precipitator cannot the problem of lightweight oil in effective elimination coal mine gas. The present invention proposes that a kind of technique is advanced, cost is low first, the de-technique except lightweight oil and device before scientific and reasonable oil shale oil-refining emission power generation.
The technical scheme of the present invention is: a kind of de-device except lightweight oil in resinous shale refining tail gas, comprise the eddy flow plate spray catcher, whirlwind trap for oil, high pressure positive blower, pressure-reducing cushioning cabinet and the thionizer that are connected successively by pipeline, described eddy flow plate spray catcher is all connected with storage tank with the bottom of whirlwind trap for oil, is connected a light oil tank in the air port that goes out of high pressure positive blower by high pressure valve.
A kind of de-technique except lightweight oil in resinous shale refining tail gas, comprise the following steps, oil shale oil-refining tail gas is first through an eddy flow plate spray catcher, again by a whirlwind trap for oil, again through high pressure positive blower, finally entering pressure-reducing cushioning cabinet, enter thionizer and carry out desulfurization after gaseous tension is stable, the gas after desulfurization is used for generating set generating; High pressure positive blower goes out air port and is provided with high pressure valve to light oil tank pipeline, closes high pressure valve after the full lightweight oil of light oil tank storage, and high pressure valve opened again by light oil tank lightweight oil after removing.
The lower liquid that described eddy flow plate spray catcher, whirlwind catch tar device enters storage tank through water seal and collects the de-mink cell focus removed.
The de-tail gas except mink cell focus is pressurized to after certain pressure value de-except lightweight oil through high pressure positive blower, and this force value is 110-130Kpa.
The de-tail gas except lightweight oil enters pressure-reducing cushioning cabinet, and after gaseous tension is stable, the force value after stable is that 6-7Kpa enters thionizer and carries out desulfurization.
It is an advantage of the invention that: not only solve in refining tail gas lightweight oil be difficult to de-except and easily cause that sweetening agent in FGD-Flue gas desulphurization process is poisoning and the problem such as the long-pending carbon of methane electrical generation machine, reclaim again a large amount of lightweight oil, add business economic benefit, significantly reduce the production cost of enterprise, economize on resources, oil shale resources utilising efficiency is further enhanced. There is significant economy, environmental protection and social benefit

Embodiment
Further describing the present invention below in conjunction with specific embodiment, the advantage and disadvantage of the present invention will be more clear along with description. But these embodiments are only exemplary, the scope of the present invention is not formed any restriction. Those skilled in the art should understand that, the details of technical solution of the present invention and form can be modified or replace lower without departing from the spirit and scope of the present invention, but these amendments and replacement all fall within the scope of protection of the present invention.
See Fig. 1, the present invention relates to a kind of de-device except lightweight oil in resinous shale refining tail gas, comprise the eddy flow plate spray catcher 1, whirlwind trap for oil 2, high pressure positive blower 3, pressure-reducing cushioning cabinet 4 and the thionizer 5 that are connected successively by pipeline, described eddy flow plate spray catcher 1 is all connected with storage tank 7 with the bottom of whirlwind trap for oil 2, is connected a light oil tank 8 in the air port that goes out of high pressure positive blower 3 by high pressure valve 9.
Also relate to a kind of de-technique except lightweight oil in resinous shale refining tail gas, comprise the following steps, oil shale oil-refining tail gas 10 is first through an eddy flow plate spray catcher 1, again by a whirlwind trap for oil 2, again through high pressure positive blower 3, finally entering pressure-reducing cushioning cabinet 4, enter thionizer 5 and carry out desulfurization after gaseous tension is stable, the gas after desulfurization is used for generating set 6 and generates electricity; High pressure positive blower 3 goes out air port and is provided with high pressure valve 9 to light oil tank 8 pipeline, closes high pressure valve after the full lightweight oil of light oil tank storage, and high pressure valve opened again by light oil tank lightweight oil after removing.
The lower liquid that described eddy flow plate spray catcher, whirlwind catch tar device enters storage tank through water seal and collects the de-mink cell focus removed, can liquid macromole mink cell focus in effective elimination tail gas.
The de-tail gas except mink cell focus is pressurized to after 110-130KPa de-except lightweight oil through high pressure positive blower.
