Description
A kind of light oil recovery apparatus for oil tank, it belongs to Petro-Chemical Machinery, can be used for the various large-scale oil storage tanks of oil production, transportation and oil depot etc., is a kind of energy saver.
In petroleum collection, transportation and storage process, all need to use various tuns that crude oil is loaded.For various tuns, for safety and stressed consideration, all can only adopt normal pressure to store, and tun is communicated with the external world, serve as zero substantially with the pressure reduction inside and outside the maintenance storage tank.But owing in the crude oil multiple hydrocarbon component is arranged, when storing, there is quite a few lightweight oil from crude oil, to evaporate, do not increase for keeping pressure of storage tank, must be with its exhaust to atmosphere.Based on crude character and gathering and transferring process different, this waste be from ten thousand/ do not wait to one of percentage.This not only causes waste, and contaminated environment.There is other petrol storage tank to adopt a big jar air extractor to solve this problem now.But since the equipment complexity, the operation requirements height, and management control difficulty adopts few in practice.Because the development of petrochemical complex, the commodity value of lighter hydrocarbons improves day by day in recent years, and reclaiming lighter hydrocarbons from big jar will put on the agenda.
The objective of the invention is to invent a kind of light oil recovery apparatus for oil tank.It need not the personal management, can handle the lightweight oil that volatilizees in the petrol storage tank automatically and also be reclaimed, and is simple in structure, reliable operation.
Structure of the present invention as shown in Figure 1.It has electrical motor 1, compressor 2, intercepting basin 3, it is characterized in that: also have housing 4, refrigerating coil 5, radiator coil tube 6, air restrictor 7, in refrigeration screwed pipe 5, radiator coil tube 6 and compressor 2 the freon refrigeration medium is arranged.
Accompanying drawing 1 is structure of the present invention and the scheme drawing that is connected with the oil storage jar.Except that above-mentioned regenerative apparatus is formed, also have oil storage upper end opening 11, fly net 9 and rain retaining canopy 10.
In the present invention, electrical motor 1, compressor 2, refrigerating coil 5, radiator coil tube 6 and air restrictor 7 have been formed a fefrigerator, housing terminates at oil storage upper end opening 11 places for 4 times, and housing 4 upper ends are connected to the fly net 9 and the rain retaining canopy 10 at ancestral petroleum holding vessel top end opening 11 places.The light hydrocarbon gas of being discharged by opening 11 enters in the housing 4 of the present invention, refrigerating coil 5 is because freon refrigeration medium wherein produces low temperature after the adiabatic expansion in air restrictor 7, the light hydrocarbon gas that enters is cooled off, lighter hydrocarbons cooling back liquefaction is lightweight oil, is transported to by intercepting basin 3 and goes storage in the light oil storage tank.
The present invention is simple in structure, and it reclaims the light hydrocarbon gas liquefaction of oil storage jar discharge by the method for refrigeration.It need not the personal management, can handle the lightweight oil that volatilizees in the petrol storage tank automatically and be reclaimed reliable operation.
In the present invention, electrical motor 1, compressor 2, radiator coil tube 6 can use the movement of existing air-conditioning machinery or refrigerator-freezer to reequip, and the present invention does not have specific (special) requirements.Can put into the explosion-proof shell that can be added with to electrical motor 1 and compressor 2, explosion-proof shell makes electrical motor 1 and compressor 2 sealings, only stays refrigerant to import and export and cable port, can satisfy the present invention like this and use in the working environment of requirement of explosion proof is arranged.
Refrigerating coil 5 among the present invention can use the copper pipe coiling, can affixed heat absorption fin for strengthening area of contact, and the light hydrocarbon gas that is discharged from contacts cooling liquid with it, falls into following intercepting basin 3.The temperature of the fefrigerator cold junction among the present invention (refrigerating coil 5 ends) can remain on-5 ℃ to+5 ℃, and the hydrocarbon components condense of carbon more than 5 in the exhaust got final product.Radiator coil tube 6 among the present invention can be a water cooled, and also the form of coiled screwed pipe is put into one section water pipe that joins with cooling water pipeline.Radiator coil tube 6 among the present invention also can be an air cooling, adds radiating fin on radiator coil tube 6, increases dissipating area.The start and stop control of refrigerating compressor of the present invention can be used the control method of refrigerator-freezer or air-conditioning, puts into temperature element in housing, by the start and stop of temperature automatic compensation compressor, does not need the personal management.
Can be at a distance adjunction heat pipe 8 of refrigerating coil 5 upper and lower sides of the present invention, as shown in Figure 2.When work, by the exhaust of refrigerating coil 5, after condensing, most of lighter hydrocarbons wherein fall into intercepting basin 3, and the remaining gas that can not liquefy is discharged in the outside air.Because the residual gas that is discharged in the outside air is cooled, temperature is lower, and for reclaiming this part energy, available heat pipe 8 is connected across a distance, two ends up and down of refrigerating coil 5.Absorb the heat of just from oil storage upper end opening 11, discharging gas with heat pipe 8, and it is passed to the residual gas that will be discharged in the outside air by heat pipe 8.Heat pipe 8 can be a gravity assisted heat pipe, is added with heat radiation and heat absorption fin at the two ends of heat pipe.Heat transfer medium in the heat pipe 8 can be ethanol, ether or fluorine Lyons.
For common large-scale storage tank, the use motor is that 2～5 kilowatts fefrigerator just can meet the demands.In the more occasion of processed gas, can use the method for many playscripts with stage directions contrive equipment and coupling to solve.
