Description of drawings
Accompanying drawing is that film separates the structure chart that reclaims petroleum system with transformation absorption overlapping method.
The specific embodiment
Film as shown in the figure separates the recovery petroleum system with transformation absorption overlapping method, the outlet of the oil tank 9 in this system is connected with the import of compressor 2 through the first magnetic valve V1 by pipeline, pressure transmitter 1 is connected between the first magnetic valve V1 and oil tank 9 outlets, the outlet of compressor 2 is connected through the import of piping with diffusion barrier 3, first gas outlet of diffusion barrier 3 is connected on the air inlet of vavuum pump 4 through piping, the import of the outlet of vavuum pump 4 and oil tank 9 is joined, second outlet of diffusion barrier 3 is connected with the import of absorber 5 by the second magnetic valve V2, and first outlet of absorber 5 is connected with drain valve 7 by check valve 6.Second outlet of absorber 5 is connected with the import of vavuum pump 4 by the 3rd magnetic valve V3.Pressure transmitter 1 is used for the oil-air pressure of monitoring system, and this signal is transferred to electric cabinet 8, and negative 8 duties of electric cabinet are responsible for the signal controlling of whole system, and the startup of decision systems is still closed.The oil gas that compressor 2 will need to separate compresses, and diffusion barrier 3 carries out primary Oil-gas Separation with high-concentration oil vapor, and vavuum pump 4 will carry out the gasoline that high concentration after the Oil-gas Separation sees through oil gas and self-solidifying through diffusion barrier 3 and draw back oil tank 9.Absorber 5 will carry out secondary Oil-gas Separation through the saturating residual air body of diffusion barrier 3, and drain valve 7 will drain in the atmosphere through the cleaned air after twice Oil-gas Separation.
Serial connection air inlet spark arrester 10 between the first magnetic valve V1 and oil tank 9 outlets, the air inlet of air inlet spark arrester 10 is connected by pipeline with oil tank 9 outlets, and the gas outlet of air inlet spark arrester 10 is connected with the first magnetic valve V1.Air inlet spark arrester 10 can effectively reduce disaster hidden-trouble, improves the security of system.
Serial connection return-air spark arrester 11 between the outlet of vavuum pump 4 and oil tank 9 imports, the air inlet of return-air spark arrester 11 is connected with the outlet of vavuum pump 4, and the gas outlet of return-air spark arrester 11 is connected by the import of pipeline with oil tank 9.Serial connection return-air spark arrester 11 between vavuum pump 4 outlets and oil tank 9 imports, the security that further improves system.
When pressure transmitter 1 monitors oil-air pressure greater than 0.8 breather valve, 12 upper limit pressure P max signal is transferred to electric cabinet 8, electric cabinet 8 sends the signal of telecommunication to other elements, and system starts automatically.The first magnetic valve V1, the second magnetic valve V2 opens, and the 3rd magnetic valve V3 closes, compressor 2, vavuum pump 4 starts.After compressor 2 is compressed to 130Kpa enters gas separation membrane 3 and carry out the Oil-gas Separation first time, the gasoline cooled via return air spark arrester 11 that the high concentration that vavuum pump 4 is extracted out sees through oil gas and self-solidifying returns oil tank 9 to high-concentration oil vapor by air inlet spark arrester 10; Saturating residual air part gas concentration this moment of diffusion barrier 3 has dropped to and enters active carbon adsorption device 5 about 2-4% and further adsorb, realizes the Oil-gas Separation of low secondary, and the air that reaches discharge standard after adsorbing is discharged in the atmosphere by drain valve 7 through check valve 6.One thief hatch 13 is set between check valve 6 and drain valve 7, can monitors the composition of the air of discharge at any time.
Along with system starts, the oil-air pressure in the oil tank 9 constantly descends, and after oil-air pressure was less than-0.8 breather valve 12 threshold pression Pmin, system entered holding state automatically, the first magnetic valve V1, and the second magnetic valve V2 closes.Compressor 2, vavuum pump 4 is out of service.After oil-air pressure was once more greater than 0.8 breather valve, 12 upper limit pressure P max, system can start once more.
Because it is very low to enter the gas concentration of active carbon adsorption device 5, absorber 5 saturated preceding working time design loads were much larger than 24 hours, therefore only need desorb once to get final product every day. system enters desorption state automatically behind the morning every day 3:00, the first magnetic valve V1, the second magnetic valve V2 closes, and compressor 2 is out of service, vavuum pump 4 starts automatically, the 3rd magnetic valve V3 opens, and after absorber 5 desorbs were finished, system entered holding state once more automatically.
