Description
Technical field
The present invention relates to environmental protection and field of energy-saving technology, refer in particular to a kind of based on solar photovoltaic powered and reclaim the system of the various organic vapors such as oil gas by condensation and absorption integrated technique.
Background technology
In fields such as oil, petrochemical industry, paint (coating), traffic, because being very easy to volatilization in the processes such as production, storage, transportation, sale, use, the various volatile organic matters (VOCs) such as gasoline produce very serious organic vapor discharge.The a large amount of evaporations of this organic vapor are also directly discharged into atmosphere, not only cause serious quantity loss and Quality Down (thereby having brought great economic loss), and have seriously polluted atmospheric environment and left great disaster hidden-trouble.The improvement of organic exhaust gas and recycling treatment, the first key technology is how to separate VOCs and air.The separation method of VOCs and air has absorption process, absorption method, condensation method and embrane method etc. at present.Various VOCs recovery methods all have pluses and minuses and the scope of application.For example, absorption process oil-gas recovery method contacts with absorbent by oil gas, air Mixture, different solubility according to different component in absorbent, be that oil-gas component is dissolved in this absorbent formation solution (rich absorbent), undissolvable constituent of air is retained in gas phase, so the component of former mist is separated.Therefore absorption process has obvious advantage for the oil gas of processing high concentration, large flow, the quality of recovering effect depends primarily on absorbent.Absorption method is conducive to control in recovery system tail gas gas concentration in very low level, but its exist heat of adsorption obviously, desorb is more difficult, reach the problems such as time of equilibrium adsorption is long, therefore be particularly suitable for reclaiming the oil gas of low concentration, low discharge, and should serve as the subsequent treatment of some group technology.Absorption method reclaims high-concentration oil vapor or other VOCs, while being particularly useful for reclaiming ketone, ester class, alcohols and unsaturated hydrocarbons, active carbon layer deteriorated (charing) may occurring and even catch fire.Condensation method can directly be recovered to oil product, for the oil gas of processing high concentration, middle flow, has obvious advantage.But simple condensation method condensation temperature will be lower than below-70 ℃, just can guarantee that the rate of recovery reaches 90% left and right, correspondingly refrigeration system is more complicated.Meanwhile, also use low temperature material and increase the links such as insulation, defrosting, cost of investment and operating cost are all higher.Membrane separation process Investigation of Petroleum Vapor Recovery Technology, as a new technology, is in research and development, especially high performance membrane material is developed.At present, domestic and international useful organic film separates and reclaims VOCs, but film is short service life, and investment and operating cost are larger.For this reason, the integrated technology of different recovery methods is just becoming the emphasis of people's research.Integrated technology, because combine rightly the advantage of two or more technology, reaches the technology complementation of height, not only can relatively easily realize effective control of exhaust of oil, technical costs can also be reduced greatly.
In current oil-gas recovery method, no matter be single method or integrated approach, the relevant device in its retracting device is as refrigeration compressor, vavuum pump, and its power resources such as watch-dog are the electric main adopting mostly, energy consumption is larger, and the operating cost that oil gas reclaims is higher.And solar energy is to utilize clean reproducible energy the most widely, it is ripe that solar photovoltaic powered technology has been tending towards, and cost is in continuous reduction, this technology can less or not rely on civil power, both can complete oil-gas recovery device supply of electric power, can also provide electric power to systems such as the air-conditioning of affiliated structures, illuminations.In short of electricity or there is no the place of civil power, more can bring into play the effect of its uniqueness.Utilize the VOCs retracting device of Driven by Solar Energy more energy-conservation, because solar energy power generating is just in time synchronizeed with the running time of petrochemical industry, oil VOCs retracting device.
At present, adopt condensation adsorption integrated technology to reclaim the system of oil gas at home and abroad, its oil-gas recovery device power resources are all to adopt electric main.Chinese Patent Application No. is 200710060342.2 disclosed petrol station photoelectric complementary absorption condensation adsorption variable frequency oil gas recycling methods, and its oil gas removal process is comprised of 2 links of 3 techniques of 2 kinds of energy.2 kinds of energy are solar energy and the conventional electric power energy, solar energy provides the energy for the oil gas absorption vacuum equipment of recovery process and the circulating pump of solvent absorption process, and the conventional electric power energy is to provide the energy for refrigeration plant and other equipment of condensation recovery process, the direct current that solar panel is converted to still needs to convert to alternating current and is supplied to consumer again.3 techniques are solvent absorption, condensation absorption, the absorption of the oil gas degree of depth.The one-level oil gas of centralized recovery when 2 links are RTC unloading reclaims link and the nozzle secondary oil gas that oiling is reclaimed to client vehicles reclaims link, and it is to enter solvent absorption device, condensation absorption plant, oil gas degree of depth adsorbent equipment through oil collecting pipe to reclaim successively that one-level reclaims the oil gas that link collects, and the oil gas that secondary recovery link produces only enters oil gas degree of depth adsorbent equipment through oil collecting pipe and reclaims.Separately having Chinese Patent Application No. is the adsorption variable frequency oil gas recycling method of 200710060338.6 disclosed moving condensations and light-electricity complementary, the method is that an oil gas that produces oil gas while utilizing the oil truck of Tape movement condensed oil-gas reclaimer to complete by oil truck to gas station's tank unloading reclaims, the fixed absorption oil-gas recovery device in gas station complete to through absorb, condensed oil-gas reclaimer tail gas after treatment carries out that secondary oil gas reclaims and nozzle is the oil gas recovery that user produces while refueling, and solar energy is only also to provide energy for gas station's absorption oil-gas recovery device, also need to be supplied to again consumer after DC-AC conversion.
