Referring to fig. 1, an oil gas recovery device provided by an embodiment of the present invention includes two major components: an oil gas recovery tower 10 and an adsorption tower 20. The oil gas recovery tower 10 is used for collecting oil gas mixture generated in the loading, unloading and carrying processes of the oil tank truck 1; the adsorption tower 20 separates the oil gas molecules from the air molecules in the oil gas mixture to obtain pure oil gas molecules, and converts the oil gas into oil products to be transmitted to the oil storage tank 2. Therefore, the oil gas recovery tower 10 can be communicated with the oil tank truck 1, and the oil gas mixture generated by the oil tank truck 1 can be transported into the oil gas recovery tower 10 through a pipeline; the adsorption tower 20 is communicated with the oil gas recovery tower 10, and the collected oil gas mixture can be transported to the adsorption tower 20; the adsorption tower 20 is communicated with the oil storage tank 2, and the recovered oil can be transported to the oil storage tank 2 after the adsorption tower 20 completes adsorption.
The oil tank truck 1 is communicated with the oil gas recovery tower 10 through a pipeline, so that the oil gas mixture in the oil tank truck 1 can be collected into the oil gas recovery tower 10 through the pipeline. Because oil gas recovery tower 10 and adsorption tower 20 intercommunication, the oil gas mixture accessible pipeline discharges in adsorption tower 20, and adsorption tower 20 can be through inside adsorption, with the oil gas material adsorption to the adsorbed substance on, remaining air molecule can not be adsorbed and live, can discharge the air to the atmosphere in the way, and the adsorbed oil gas then breaks away from the adsorbed substance through analytic effect, forms liquid oil, is being in with liquid oil recovery to oil storage tank 2 afterwards. The oil gas recovery device has simple result, but can recover a large amount of oil gas recyclable oil gas energy sources into the oil storage tank 2, thereby not only saving the energy sources and realizing the recycling, but also avoiding the environmental pollution to the atmosphere caused by the discharged oil gas mixture.
Referring to fig. 1, in some embodiments of the present invention, the oil and gas recovery apparatus further comprises a first vacuum pump 11, a second vacuum pump 21, and a third vacuum pump 41. In order to quickly collect oil gas molecules generated by the oil tank truck 1 into the oil gas recovery tower 10, the first vacuum pump 11 is arranged between the oil gas recovery tower 10 and the oil tank truck 1; similarly, in order to rapidly transport the collected oil gas molecules to the adsorption tower 20, the second vacuum pump 21 is arranged between the oil gas recovery tower 10 and the adsorption tower 20; finally, in order to liquefy the gas-phase oil gas molecules into liquid-phase oil gas molecules, a third vacuum pump 41 is arranged between the adsorption tower 20 and the oil storage tank 2, the third vacuum pump 41 forms a vacuum negative pressure environment in the adsorption tower 20, and can liquefy the adsorbed oil gas molecules into liquid oil products and convey the liquid oil products into the oil storage tank 2.
Referring to fig. 1, in some embodiments of the present invention, the oil gas recovery tower 10 may communicate with at least one tank truck 1, so in order to increase the recovered oil gas and improve the efficiency of recovering the oil gas, the oil gas recovery tower 10 may be provided with a plurality of pipelines to communicate with a plurality of tank trucks 1, such as two, three, etc. It should be understood that the first electromagnetic valve 12 should be provided on each pipeline for recovering oil gas, and when the first vacuum pump 11 is operated, each pipeline for recovery is operated at the same time, but in order to avoid that some recovery pipelines are not communicated with the tank wagon 1, so that air is sucked or the pipelines are damaged due to unstable air pressure, the first electromagnetic valve 12 is provided on each pipeline for recovery, that is, the first electromagnetic valve 12 is provided between the oil gas recovery tower 10 and the tank wagon 1. If the number of the recovery pipelines is two, and one of the recovery pipelines is in an idle state, the first electromagnetic valve 12 on the recovery pipeline is closed under the control of electricity, and the first electromagnetic valve 12 on the other recovery pipeline is controlled to be opened, so that the oil-gas mixture from the oil tank truck 1 can be collected.
Further, when the first vacuum pump 11 continuously pumps the oil-gas mixture in the tank truck 1 to the oil-gas recovery tower 10, in order to detect the air pressure value in the recovered pipeline, a first pressure sensor 13 may be disposed between the oil-gas recovery tower 10 and the first electromagnetic valve 12, and the first pressure sensor 13 may be connected to a pointer instrument, which displays the pressure in the pipeline, so that a technician can conveniently read data and know the pressure condition in the pipeline in real time.
Referring to fig. 1, in some embodiments of the present invention, in order to recover oil and gas molecules without interruption and improve the efficiency of recovery and adsorption, the number of the adsorption towers 20 is two or more, and may be three, or four, or even more, and may be determined according to the molecular weight of the recovered oil and gas. A second electromagnetic valve 22 is arranged between the adsorption tower 20 and the oil gas recovery tower 10, and the second electromagnetic valve 22 can control the connection and disconnection of the pipeline between the adsorption tower 20 and the oil gas recovery tower 10, so that oil gas molecules can be controlled to enter the adsorption tower 20. That is, if the number of the adsorption towers 20 is two, and one of the adsorption towers is in an analytic state, the work of adsorbing the oil gas molecules cannot be completed, the second electromagnetic valve 22 is used to block the communication between the oil gas recovery tower 10 and the adsorption tower 20, and the second electromagnetic valve 22 between the other adsorption tower 20 and the oil gas recovery tower 10 is opened to transfer the oil gas molecules in the oil gas recovery tower 10 to the adsorption tower 20. Therefore, it can be understood that the adsorption towers 20 can continuously adsorb the oil gas molecules by more than two adsorption towers 20, and the purpose of improving adsorption recovery is further achieved.
Further, the end that produces oil of adsorption tower 20 is provided with second pressure sensor 23, and second pressure sensor 23 can show the oil pressure of the end that produces oil of adsorption tower 20 on the scale instrument of being connected with it, makes things convenient for the technical staff to read oil pressure data for the technical staff is controllable to know the oil pressure condition in the adsorption tank a lot, avoids the oil pressure in the adsorption tower 20 too high, damages adsorption tower 20.
In some embodiments of the present invention, a layer of regenerable activated carbon (not shown) is disposed within adsorption column 20. Because adsorption tower 20 is in the confined state, be unfavorable for the change of active carbon, so adopt can palingenetic active carbon layer, avoid often changing active carbon layer to reduce the change time, improve adsorption efficiency. The coal-based activated carbon can be adopted, has strong renewable capability and good analytic effect, is more renewable, and can reduce the frequency of replacing the activated carbon; carbon tetrachloride may also be used as the material in the activated carbon layer, but it is emphasized that the activated carbon material of the activated carbon layer listed herein is not particularly limited.
Further, in some embodiments of the present invention, the adsorption tower 20 is provided with an exhaust gas pipe (not shown) which is communicated with the adsorption tower 20, and the exhaust gas pipe is provided with a gas concentration detector (not shown). After the oil gas molecules are adsorbed by the activated carbon layer in the adsorption tower 20, air is left in the adsorption tower 20 finally due to the fact that the activated carbon has no adsorption capacity on the air, and therefore the air can be discharged into the atmosphere from the exhaust pipeline.
Referring to fig. 1, in some embodiments of the present invention, an oil and gas amount sensor (not shown) is disposed inside an oil and gas recovery tower 10, a graduated scale 14 is disposed outside the oil and gas recovery tower 10, and the graduated scale 14 is electrically connected to the oil and gas amount sensor. In the oil gas source constantly sent into oil gas recovery tower 10, in order to observe the oil gas volume in the oil gas recovery tower 10 more directly perceivedly, accessible scale 14 direct observation reachs, the inside oil gas volume sensor of oil gas recovery tower 10 is more sensitive to scale 14 can show its inside oil gas volume accurately. When the oil gas amount reaches the preset value, the second electromagnetic valve 22 can be opened, and the oil gas mixture is sent into the adsorption tower 20 for sufficient adsorption. If the oil gas amount does not reach the preset value, the adsorption effect in the adsorption tower 20 is reduced.
Referring to fig. 1 and 2, in some embodiments of the utility model, the lower ends of the oil and gas recovery tower 10 and the adsorption tower 20 are each provided with a cavity 24, and the cavity 24 may accommodate a piping installation. It is conceivable that since the oil gas recovery tower 10 and the adsorption tower 20 are arranged up and down, the outlet is arranged at the lower end to better discharge the residual substances in the tower, and therefore, a cavity 24 is provided at the bottom of the tower bottom, and a pipe communicating with the outlet at the bottom of the tower is installed in the cavity 24 to directly discharge the substances in the tower. If the opening is arranged at the side end of the tower bottom, the discharge of the substances in the tower is not facilitated. Particularly, the oil-phase oil-gas molecules in the tower contents of the adsorption tower 20 need to be discharged through the bottom opening of the tower bottom, while the openings on the side of the tower bottom are very unfavorable for discharging the oil-phase substances.
Referring to fig. 1 and 3, the above embodiment will be specifically described by taking a complete oil and gas recovery process as an example. The description is as follows:
the oil tank truck 1 is communicated with an oil gas recovery tower 10, the oil gas mixture in the oil tank truck 1 is pumped into the oil gas recovery tower 10 through a first vacuum pump 11, if the oil tank truck is two oil tank trucks 1, two recovery pipelines are arranged, two first electromagnetic valves 12 independently control the recovery pipelines are opened, two first electromagnetic valves 12 are opened simultaneously, the oil gas mixture can be pumped into the oil gas recovery tower 10 through the first vacuum pump 11, the oil gas pressure in the recovery pipelines is monitored in real time through a first pressure sensor 13, and the oil gas amount in the oil gas recovery tower 10 is monitored in real time through an oil gas amount sensor in the oil gas recovery tower 10. If the oil tank truck 1 is adopted, one of the first electromagnetic valves 12 is closed, and the closing of the recovery pipeline is realized.
When the oil gas volume in the oil gas recovery tower 10 reaches the preset value, the second vacuum pump 21 and the second electromagnetic valve 22 can be opened, the oil gas mixture in the oil gas recovery tower 10 is pumped to the adsorption tower 20 by the second vacuum pump 21, oil gas molecules in the oil gas mixture can be adsorbed in the reproducible active carbon layer, and unadsorbed air molecules or other waste gases are discharged to the atmosphere by the exhaust pipeline. The gas concentration detector on the exhaust pipeline can detect whether the discharged waste gas meets the discharge standard, if not, the exhaust pipeline needs to be closed to continue adsorption treatment, which means that oil gas molecules are not completely adsorbed; otherwise, the exhaust gas is discharged. After the oil gas is completely discharged, the exhaust pipeline is closed, the third vacuum pump 41 is started, the third vacuum pump 41 creates a vacuum negative pressure environment for the adsorption tower 20, the oil gas molecules adsorbed on the activated carbon can be separated, the activated carbon is analyzed and regenerated, the separated oil gas molecules are absorbed by the liquid oil in the tower to form liquid oil, and the liquid oil is sucked by the third vacuum pump 41 and discharged into the oil storage tank 2. When one of the adsorption towers 20 is in analysis operation, the new oil-gas mixture is prohibited from being discharged, so the second electromagnetic valve 22 connected with the adsorption tower 20 is closed, and the second electromagnetic valve 22 of the other adsorption tower 20 is opened to complete the operation of charging the adsorption tower 20 for adsorbing oil-gas molecules. Therefore, it can be understood that when one of the adsorption towers 20 performs desorption operation, the other adsorption tower 20 may perform adsorption operation, and the adsorption and desorption operations of two or more adsorption towers 20 may be controlled only by electrically operating the second solenoid valve 22 remotely. Therefore, the process of oil gas recovery can be continuously realized, and the efficiency of oil gas recovery is further improved.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
