Description

Technical Field

[0001] This utility model relates to the field of oil and gas recovery technology, specifically a multi-stage adsorption oil and gas recovery device. Background Technology

[0002] Oil and gas recovery is an energy-saving and environmentally friendly new technology. It utilizes this technology to recover oil and gas emitted during storage, transportation, and loading / unloading, preventing air pollution caused by oil and gas volatilization, eliminating safety hazards, and improving energy utilization efficiency while reducing economic losses, thus yielding substantial economic benefits. Common methods include adsorption, absorption, condensation, and membrane separation systems.

[0003] Existing oil and gas recovery systems typically employ multi-stage adsorption. However, during actual operation, the oil and gas contain particulate matter that requires adsorption and filtration. Current operating methods generally involve directly adsorbing particulate matter through filters and using other methods to adsorb other impurities. However, adsorption using multiple layers of filters alone can easily cause large particles to get stuck in the filter mesh. Furthermore, the degree of oil and gas particle removal can severely affect the service life of the materials used in subsequent oil and gas impurity adsorption, filtration, and recovery equipment. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a multi-stage adsorption oil and gas recovery device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage adsorption oil and gas recovery device, comprising...

[0006] The recycling tank has a filter cover fixedly connected inside and a tank cover fixedly connected to the top of the recycling tank. A set of symmetrical conveying pipes is set at the top of the recycling tank. A slot is opened at the top of the recycling tank and a slag discharge port is fixedly connected to the bottom of the recycling tank.

[0007] A press-to-filter mechanism is located directly above the can lid;

[0008] The bottom of the press-to-filter mechanism extends into the interior of the filter cover;

[0009] The bottom end of the conveying pipe extends through the tank cover to the inner bottom end of the filter cover, and the slag discharge port is funnel-shaped. The aforementioned pressing filter mechanism includes a servo motor, a connecting shaft, a bracket, a movable ring, and a filter screen. The bracket is movably connected to the top end of the connecting shaft via bearings, and the output end of the servo motor passes through the bracket and is fixedly connected to the connecting shaft. The movable ring is movably connected to the outside of the connecting shaft via threads, and the filter screen is fixedly connected to the outside of the movable ring.

[0010] As mentioned above, both ends of the bracket are fixedly connected to the top of the recycling tank, and the bottom end of the connecting shaft is movably connected to a fixing strip through a bearing. The two ends of the fixing strip are respectively fixedly connected to the outside of the conveying pipe.

[0011] As described above, the filter screen is circular and fits the filter cover. The bottom end of the conveying pipe extends through the filter screen to the inside of the slag discharge port, and the connection between the conveying pipe and the filter screen is slidably connected.

[0012] As described above, the slot is arc-shaped, and an installation strip is engaged inside the slot. The installation strip is also arc-shaped, and several adsorption rods are connected to the bottom of the installation strip in a circular arrangement via a rotating shaft. The adsorption rods are made of activated carbon.

[0013] As mentioned above, several adsorption grooves are opened on the outer side of the adsorption rod, and the bottom end of the adsorption rod is movably connected to the bottom of the recovery tank through a bearing. The adsorption rods are all located on the opposite side of the recovery tank and the filter cover.

[0014] As mentioned above, the bottom of the recycling tank is fixedly connected to a discharge trough, and the inner side of the discharge trough is fixedly connected to the outer side of the slag discharge port. Several connecting pipes are fixedly connected to the bottom of the discharge trough.

[0015] Compared with existing technologies, this multi-stage adsorption oil and gas recovery device has the following advantages:

[0016] I. This utility model utilizes a press-and-filter mechanism, with a servo motor driving the connecting shaft to rotate. At this time, the connecting ring moves the filter screen towards the slag discharge port, while the filter screen slides on the outer wall of the conveying pipe. This facilitates the pushing of particles attached to the filter cover and the outer wall of the conveying pipe into the slag discharge port, preventing particles from clogging the filter screen and escaping from the inside of the filter cover. Furthermore, during the descent of the filter screen, the rising oil and gas undergo initial filtration, improving the initial filtration efficiency of the oil and gas, reducing the adsorption load of the oil and gas, and extending the service life of the adsorption material.

[0017] II. This utility model, through the setting of adsorption rods and discharge tanks, allows oil and gas to undergo primary filtration through a filter screen and filter cover before entering the recovery hood and filter cover. At this time, the adsorption rods are driven by the oil and gas flow to rotate slowly, adsorbing extremely small particles and harmful gases in the oil and gas. Subsequently, the oil and gas after adsorption and filtration are transported to other equipment through the discharge tank and connecting pipe for further processing. This is beneficial for quickly filtering particles and some easily absorbed harmful substances in the oil and gas, reducing the difficulty of subsequent oil and gas adsorption and recovery.

[0018] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-4 As shown, this utility model provides a technical solution: a multi-stage adsorption oil and gas recovery device, including a recovery tank 1, a filter cover 2 fixedly connected inside the recovery tank 1, and a tank cover 3 fixedly connected to the top of the recovery tank 1. A pressing filter mechanism 4 is provided directly above the tank cover 3, and the bottom end of the pressing filter mechanism 4 extends into the interior of the filter cover 2. A set of left and right symmetrical conveying pipes 5 are provided at the top of the recovery tank 1, and the bottom end of the conveying pipes 5 extends through the tank cover 3 to the bottom of the interior of the filter cover 2. A slot 6 is opened at the top of the recovery tank 1, and a slag discharge port 7 is fixedly connected to the bottom of the recovery tank, and the slag discharge port 7 is funnel-shaped.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the pressing filter mechanism 4 includes a servo motor 401, a connecting shaft 402, a bracket 403, a movable ring 404, and a filter screen 405. The bracket 403 is movably connected to the top of the connecting shaft 402 via a bearing, and the output end of the servo motor 401 passes through the bracket 403 and is fixedly connected to the connecting shaft 402. The movable ring 404 is movably connected to the outside of the connecting shaft 402 via a thread, and the filter screen 405 is fixedly connected to the outside of the movable ring 404. Both ends of the bracket 403 are fixedly connected to the top of the recovery tank 1. The bottom end of the connecting shaft 402 is movably connected to a fixing strip 8 via a bearing, and both ends of the fixing strip 8 are fixedly connected to the outside of the conveying pipe 5. The filter screen 405 is circular and fits the filter cover 2. The bottom end of the conveying pipe 5 passes through the filter screen 405 and extends into the interior of the slag discharge port 7, and the connection between the conveying pipe 5 and the filter screen 405 is slidably connected.

[0027] The servo motor 401 drives the connecting shaft 402 to rotate. At this time, the connecting ring drives the filter screen 405 to move towards the slag discharge port 7. Simultaneously, the filter screen 405 slides on the outer wall of the conveying pipe 5, which helps to push the particles attached to the filter cover 2 and the outer wall of the conveying pipe 5 into the slag discharge port 7, preventing the particles from clogging the filter screen 405 and escaping from the interior of the filter cover 2. Secondly, during the descent of the filter screen 405, the rising oil and gas are initially filtered, improving the initial filtration efficiency of the oil and gas, reducing the oil and gas adsorption load, and extending the service life of the adsorption material.

[0028] After the oil and gas undergo primary filtration through the filter screen 405 and the filter cover 2, they enter the recovery cover and the filter cover 2 relative to each other. At this time, the adsorption rod 10 is driven by the oil and gas flow to rotate slowly, adsorbing extremely small particles and harmful gases in the oil and gas. Subsequently, the oil and gas after adsorption and filtration is completed is transported to other equipment through the discharge tank 11 and the connecting pipe 12 to wait for further processing. This is beneficial for quickly filtering particles and some easily absorbed harmful substances in the oil and gas, reducing the difficulty of subsequent oil and gas adsorption and recovery.

[0029] like Figure 2 , Figure 3 and Figure 4 As shown, the slot 6 is arc-shaped, and an installation strip 9 is inserted inside the slot 6. The installation strip 9 is also arc-shaped. Several adsorption rods 10 are movably connected in a ring through a rotating shaft at the bottom end of the installation strip 9. The adsorption rods 10 are made of activated carbon. Several adsorption grooves are opened on the outer side of the adsorption rods 10. The bottom end of the adsorption rods 10 is movably connected to the bottom end of the recovery tank 1 through a bearing. The adsorption rods 10 are all located on the opposite side of the recovery tank 1 and the filter cover 2. The bottom end of the recovery tank 1 is fixedly connected to the discharge trough 11, and the inner side of the discharge trough 11 is fixedly connected to the outer side of the slag discharge port 7. Several connecting pipes 12 are fixedly connected to the bottom end of the discharge trough 11.

[0030] Working principle: During use, the oil and gas pipeline is connected to the conveying pipe 5, and the slag discharge pipe with a valve is fixedly connected to the slag discharge port 7. The pipeline transports the oil and gas through the conveying pipe 5 to the inside of the filter cover 2. At the same time, the servo motor 401 is started to drive the connecting shaft 402 to rotate. At this time, the connecting ring drives the filter screen 405 to move towards the slag discharge port 7. Meanwhile, the filter screen 405 slides on the outer wall of the conveying pipe 5, pushing the particles attached to the outer wall of the filter cover 2 and the conveying pipe 5 into the slag discharge port 7, preventing the particles from clogging the filter screen 405 and escaping into the inside of the filter cover 2. Secondly, the filter screen 405 performs initial filtration on the rising oil and gas during its descent. When the oil and gas enter the recovery cover and the filter cover 2 after primary filtration through the filter screen 405 and the filter cover 2, the adsorption rod 10 is driven by the oil and gas flow to rotate slowly, adsorbing the extremely small particles and harmful gases in the oil and gas. Subsequently, the oil and gas after adsorption and filtration is completed is transported to other equipment through the discharge tank 11 and the connecting pipe 12 to wait for further processing.
