Description
Technical field
The present invention relates to Investigation of Petroleum Vapor Recovery Technology field, more particularly, to a kind of gas recovery system for oil.
Background technology
Because oil product is very easy to volatilization, during gas station's oil storage tank is stored and receives and dispatches oil product, oil storage tank breathing
Caused exhaust of oil includes two kinds of forms of Big and Small Breath：Big breathing and small breathing.Small breathing refers to the heat caused by temperature changes
Swollen shrinkage, environment temperature causes pressure inside the tank change suction air and exhaust of oil；When big breathing refers to oil storage tank transmitting-receiving operation, tank
Interior gas pressure change causes oil storage tank to discharge oil gas and suction air.
Existing gasoline station oil gas discharge Treatment process is roughly divided into a stage petroleum vapor recovery, two-stage petroleum vapor recovery and three ranks
Section petroleum vapor recovery.One stage petroleum vapor recovery for oil truck to during oil storage tank emptying, the increase of oil storage pressure tank, the oil of generation
Gas is recycled to oil truck, and this process also results in the big breathing of oil storage tank and breather valve opens exhaust of oil；Two-stage petroleum vapor recovery
During referring to automobile fuel filler, the petroleum vapor recovery that automotive oil tank is produced to oil storage tank, due to national standard require gas liquid ratio be more than
1：The volume that 1, i.e. oil storage tank send liquid oil is less than petroleum vapor recovery volume, causes the increase of oil storage pressure tank to produce oil gas row
Put；Three stage petroleum vapor recoveries are also known as " reinforcement petroleum vapor recovery ", and size is exhaled caused by oil storage tank pressure change during solution transmitting-receiving
Suction is put, including Tank's Breather Valve exhaust of oil caused by a stage and two-stage recovery system, equipment.
The problem of existing following tank of oil storage tank flattens weighing apparatus and breather valve exhaust of oil：
1st, during oil storage tank transmitting-receiving operation, gas pressure change causes oil storage tank to discharge oil gas and suction air in tank.Due to
The gas liquid ratio of two-stage gas recovery system for oil is more than 1：1, the oil-gas ratio returned in tank adds the oil many, adds the oil of nature volatilization
Gas, pressure inside the tank can gradually rise, and also cause breather valve to discharge oil gas；
2nd, due to environmental change, phenomenon of expanding with heat and contract with cold, when oil storage tank system temperature is reduced, breather valve can suck air,
When oil storage tank system temperature is raised, oil evaporation aggravation, pressure inside the tank increase will；Oil storage tank carries out transmitting-receiving operation process
In, when oil tank oil-feed, due to the increase of pot liquid volume, gas pressure increases in tank, when pressure increases to breather valve pressure pole
In limited time, breather valve automatically turns on to surrounding environment and discharges gas.

Air is discharged into by the 3rd valve 53, abat-vent 6.
When in the gas that the floss hole for detecting petroleum vapor recovery exhaust unit 200 is discharged contained hydrocarbon components it is dense
When degree reaches concentration preset value, the first adsorption tanks 21 and the second adsorption tanks 22 carry out adsorption desorption alternating.Specifically, when concentration is sensed
Device, which detects the first adsorption tanks 21 and is discharged in the gas in air the concentration of contained hydrocarbon components, reaches that concentration is preset
During value, the first valve 51 and the 3rd valve 53 are closed, and the second valve 52, the 4th valve 54 and the 5th valve 55 are opened.Now,
The excessive oil gas that one adsorption tanks 21 are carried out in desorption processing, oil storage tank 1 is discharged into the second absorber, is inhaled by the second adsorption tanks 22
Attached processing.
Open in the desorption process of the first adsorption tanks 21, open the vavuum pump 3 and cooler 4 of petroleum vapor recovery exhaust unit 200, will
Hydrocarbon components on adsorption tanks are parsed, and by cooler 4 cool down after, be recovered into oil storage tank 1.In resolving
Latter end, open the 7th valve 57, introduce extraneous air adsorption tanks are purged, the carbon that will be adsorbed in the first adsorption tanks 21
Hydrogen compound composition is fully retrieved in oil storage tank 1, and makes to reclaim normal pressure in the first adsorption tanks 21, and the first adsorption tanks 21 recover to inhale
Attached ability.
When the second 22 adsorption saturation of adsorption tanks, the second valve 52 and the 4th valve 54 are closed, the first valve 51 and the 3rd
Valve 53 is opened, and it is transferred to detachment status, and the first adsorption tanks 21 for recovering adsorption capacity are switched to adsorbed state again.Specifically
Adsorption desorption process can be found in preceding sections, no longer be described in detail herein.
Gas recovery system for oil in the application, due to provided with petroleum vapor recovery exhaust unit 200, when oil storage tank 1 in storage and
, can be in advance by the petroleum vapor recovery exhaust unit 200 by oil storage tank 1 when receiving and dispatching oily pressure inside the tank moment rise during oil product
Interior unnecessary oil gas composition discharge, without directly being discharged by breather valve 9, it is to avoid the waste of oil gas and be directly discharged into big
Gas.During exhaust of oil, the hydrocarbon components that oil gas is first passed around in adsorption tanks absorption, oil gas are recovered to oil
Tank, is clean gas by the gas componant of adsorption tanks, can be directly discharged into air, realize non-pollution discharge.
Therefore, during the gas recovery system for oil integrally solves the current oil product of gas station's oil storage tank 1 storage and transmitting-receiving,
The exhaust of oil of 1 breather valve of oil storage tank 9 caused by temperature, pressure change and a stage petroleum vapor recovery and two-stage petroleum vapor recovery
