The specific embodiment
Below in conjunction with the accompanying drawing in the utility model, the technical scheme in the utility model is clearly and completely described.
Please refer to Fig. 1 and Fig. 2, the utility model intelligence secondary gas recovery system for oil comprises fuel charger 1, controller 2, nozzle 3, gauge pressure transducer 5, suction solenoid valve 6, vacuum chamber 7, vacuum pump 10, reservoir for condensation 12, canister 16, gas concentration sensor 17, circulating electromagnetic valve 18 and exhaust solenoid valve 19, fuel charger 1 is connected by the oil gas pipe with nozzle 3, and controller 2 is arranged in the fuel charger 1.
The oil gas Through Flow Line (TFL) 22 that links to each other with vacuum chamber 7 is set on the housing of nozzle 3, is connected with first check valve 4, gauge pressure transducer 5 and suction solenoid valve 6 on the oil gas Through Flow Line (TFL) 22 in turn, gauge pressure transducer 5 is connected with controller 2 by cable.Vacuum chamber 7 links to each other with reservoir for condensation 12 by vacuum pump 10, vacuum chamber 7 is provided with pressure sensor 8, reservoir for condensation 12 links to each other with canister 16, between vacuum chamber 7 and vacuum pump 10, dryer 9 can be set, between vacuum pump 10 and reservoir for condensation 12, second check valve 11 can be set, between reservoir for condensation 12 and canister 16, the 3rd check valve 15 can be set.
Reservoir for condensation 12 is provided with pressure sensor 13 and temperature sensor 14, be respectively applied for detecting uncooled pressure and temperature that becomes liquid oil gas in the reservoir for condensation 12, the oil gas that reaches the critical value (this critical value can guarantee the oil gas condensation liquefaction more than 90% separates be converted into gasoline) of baroceptor 13 and temperature sensor 14 defineds on the reservoir for condensation flows out from reservoir for condensation 12.The outlet of canister 16 links to each other with freeing pipe 20, freeing pipe 20 is provided with gas concentration sensor 17 and exhaust solenoid valve 19, the oil gas circulating pipe 21 that the node setting of freeing pipe 20 between gas concentration sensor 17 and exhaust solenoid valve 19 links to each other with vacuum pump 10, during concrete enforcement, one end of oil gas circulating pipe 21 is communicated with freeing pipe 20, and the other end is communicated with dryer 9.Oil gas circulating pipe pipe 21 is provided with circulating electromagnetic valve 18.
During work, when fuel charger 1 refueled to self-propelled vehicle by nozzle 3, the oil gas collection that produces in the refueling process was in nozzle 3.When gas concentration in the nozzle 3 reached the air pressure critical value that presets, first check valve 4 on the oil gas Through Flow Line (TFL) 22 was opened, and oil gas is by first check valve 4.5 pairs of oil gas Through Flow Line (TFL) 22 internal gas pressures of gauge pressure transducer that first check valve, 4 backs are provided with are measured, and information is passed to controller 2.During concrete enforcement, digital signal is measured and be converted to the pressure of oil gas in 5 pairs of oil gas Through Flow Line (TFL)s of gauge pressure transducer 22, sends controller 2 then to.If gauge pressure transducer 5 records in the oil gas Through Flow Line (TFL) 22 the oil gas pressure and reaches preset value (this preset value can be according to the practical experience setting, the average pressure value of the oil gas that produces when for example nozzle 3 refuels), show that this moment, nozzle 3 was in fueling state, then controller 2 control suction solenoid valve 6 and reservoir for condensation 12 are in opening; Oil gas pressure does not reach preset value in the oil gas Through Flow Line (TFL) 22 if gauge pressure transducer 5 records, and then controller 2 control suction solenoid valve 6 and reservoir for condensation 12 are in closed condition.Pressure is not negative pressure in the vacuum chamber if the pressure sensor 8 on the vacuum chamber 7 records, and then controller 2 control vacuum pumps 10 are started working, and when the pressure in making vacuum chamber 10 is negative pressure, send information to controller 2 immediately, and controller 2 cuts out vacuum pump 10.
Because vacuum pump 10 starts, at this moment oil gas flows to the reservoir for condensation 12 after being positioned at vacuum pump 10 in the 9 dry backs of process dryer under the driving of draught head, reservoir for condensation 12 bottoms have a hydraulically-controlled one-way valve to lead to recovery bin, and (this recovery bin can be arranged on the appropriate location as required, does not indicate among the figure.), oil gas flows to recovery bin by hydraulically-controlled one-way valve after reservoir for condensation 12 condensations, can prevent that fluid oil from refluxing, and liquid gasoline will be stored in the recovery bin, realize that thus the condensation of oil gas is reclaimed.
The oil gas major part is condensed into liquid state and stays in reservoir for condensation 12, the oil gas that small part reaches baroceptor on the reservoir for condensation 12 13 and the critical value of temperature sensor 14 defineds flows out from reservoir for condensation 12.At this moment through being positioned at the canister 16 behind the reservoir for condensation 12,16 pairs of oil gas of canister adsorb further reduces oil gas pressure to the oil gas of Liu Chuing again.The oil gas of canister 16 absorption blows out under the flow air effect, can prevent that canister 16 from absorbing oil gas and can not work after saturated, and the oil gas that blows out can carry out oil gas and reclaims circulation and be recovered, and specifically sees also following description.
The freeing pipe 20 that links to each other with canister 16 is provided with gas concentration sensor 17, and the gas concentration that flows out in 17 pairs of canisters 16 of gas concentration sensor is measured and sent the gas concentration value that records to controller 2 immediately.When concentration reaches when allowing to be discharged into the value of atmosphere, then controller 2 control exhaust solenoid valves 19 are opened, and circulating electromagnetic valve 18 is closed, and oil gas is discharged to atmosphere through exhaust solenoid valve 19; When concentration does not reach the value that allows release, then controller 2 control exhaust solenoid valves 19 are closed, circulating electromagnetic valve 18 is opened, with hydrocarbon flow to reservoir for condensation 12, pass through above-mentioned oil gas condensation adsorption process once more, reach the critical value that allows discharging until gas concentration, oil gas flows out from exhaust solenoid valve 19.When gauge pressure transducer 5 was sensed nozzle 3 and stopped to refuel, controller 2 control suction solenoid valve 6 are closed and reservoir for condensation 12 quits work.
Whether the utility model can start working according to the pressure Auto-Sensing nozzle of oil gas in the oil gas Through Flow Line (TFL), thereby start gas recovery system for oil automatically by the open and-shut mode of controller control suction solenoid valve and reservoir for condensation; In addition, the canister behind the reservoir for condensation of setting can further adsorb condensed oil gas, sends reservoir for condensation back to and further recycles through freeing pipe, circulating electromagnetic valve again through the oil gas of canister absorption, thereby improve the oil gas recovery utilization rate; Cooperate by gas concentration sensor and controller, make that the oil gas when concentration reaches the value that allows release just can be discharged in the air, reduce exhaust emissions.
The above; it only is the specific embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly belong to those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
