Description
Technical Field
[0001] This utility model belongs to the field of oil and gas recovery and separation technology, and in particular to an oil and gas recovery and separation device. Background Technology
[0002] Oil and gas recovery refers to the process of collecting, processing, and reusing volatile organic gases (such as gasoline vapor) during the production, storage, transportation, and sale of petroleum and its derivatives.
[0003] Oil and gas recovery and separation equipment is a complete system that uses physical / chemical methods to collect, enrich, separate components, and utilize oil and gas (such as gasoline vapor) that escapes during industrial production, storage, transportation, and sales. Its core objective is to achieve the dual functions of resource recovery and pollution control of volatile organic compounds.
[0004] Existing oil and gas recovery and separation devices generally use wire mesh demisters to filter out mist entrained in the gas. In this case, the wire mesh demister utilizes a dense structure formed by multiple layers of metal wire mesh to trap droplets with a diameter >5μm through inertial collision, diffusion interception, and gravity settling. The purified gas passes through the gaps in the wire mesh. The wire mesh demister is generally fixedly installed in the separation chamber. After the raw liquid enters the separation chamber, the oil falls into the oil tank, while the separated gas rises in the separation chamber and is filtered by the wire mesh demister. Since the wire mesh demister is located directly above the oil, the mist (containing liquid hydrocarbons, condensate, and trace impurities) captured by the wire mesh flows back to the oil zone due to gravity, forming a "backmixing" phenomenon. This causes the originally separated small particles (such as rust and polymer colloids) to re-enter the oil phase, reducing product quality.
[0005] The purpose of this invention is to provide an oil and gas recovery and separation device to solve the problems mentioned in the background art. Utility Model Content
[0006] The purpose of this invention is to provide an oil and gas recovery and separation device to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, the present invention provides the following technical solution: an oil and gas recovery and separation device, comprising an oil storage tank, a supporting frame connected to the upper end of the oil storage tank, a collection frame provided in the supporting frame, an airflow hole provided on the collection frame, a wire mesh demister provided inside the supporting frame and above the collection frame, and a plurality of top blocks provided at the upper end of the wire mesh demister, each set of top blocks having a smooth arc shape at the upper end; The upper end of the support frame is provided with a defoaming mechanism; The hydraulic telescopic arm in the defoaming mechanism extends, causing the motor in the defoaming mechanism to move downward. When the motor moves downward, it drives each set of impact plates and sealing blocks in the defoaming mechanism to move downward until the lower end of the impact plate moves to fit against the upper end of the wire mesh demister, and at the same time until the sealing block moves to the airflow hole and closes it. When the motor shaft rotates, it drives each set of support plates in the demister mechanism to rotate. When each set of support plates rotates, it drives the lower end of each set of impact plates to rotate against the upper surface of the wire mesh demister. After each set of impact plates rotates and contacts each set of top blocks in sequence, each set of impact plates moves upward and stretches each set of springs in the demister mechanism. After each set of impact plates disengages from each set of top blocks, each set of springs rebounds, causing each set of impact plates to instantly reset and impact the wire mesh demister, causing the wire mesh demister to vibrate. Furthermore, the collection frame is equipped with a scraping mechanism. When the motor shaft rotates, it drives the telescopic rod in the scraping mechanism to rotate. When the telescopic rod rotates, it drives the scraper in the scraping mechanism, which perfectly matches the shape of the collection frame, to rotate. When the scraper rotates along the surface of the collection frame and passes through the drain pipe, it moves the dirt on the surface of the collection frame into the drain pipe. The inclined drain pipe causes the dirt to move downwards until it falls into the collection box in the scraping mechanism, making it easy to collect the dirt.
[0008] Furthermore, the demister mechanism includes a hydraulic telescopic arm, a motor, a sealing block, a support plate, an impact plate, and a spring. The upper end of the support frame is provided with a hydraulic telescopic arm, and the telescopic end of the hydraulic telescopic arm is provided with a motor. The shaft of the motor extends into the support frame and passes through the wire mesh demister. A sealing block is rotatably provided at the end of the motor shaft located below the wire mesh demister. Multiple sets of support plates are provided on the section of the motor shaft located above the wire mesh demister and inside the support frame. An impact plate is vertically slidably provided on each set of support plates. Each set of impact plates is connected to the support arm by a spring, and the lower end of each set of impact plates is smoothly arc-shaped, which facilitates the instantaneous impact of the impact plate on the surface of the wire mesh demister, thereby generating vibration in the wire mesh demister and thus shaking and cleaning it.
[0009] Furthermore, the scraping mechanism includes a telescopic rod, a slide rail, a scraper, a drain pipe, and a storage box. An annular slide rail is provided on the side wall of the collection frame, and a scraper is installed inside the slide rail. A telescopic rod is provided at the upper end of the scraper, and the end of the telescopic rod away from the scraper is connected to the motor shaft. The collection frame is provided with a drain pipe, and a support frame extends from the outlet end of the drain pipe. A storage box is provided on the outer wall of the oil storage tank and below the drain pipe to facilitate the scraping and cleaning of stains on the surface of the collection frame.
[0010] Furthermore, the upper end of the support frame is provided with an exhaust pipe, and the upper end of the oil storage tank is provided with an oil inlet, so as to facilitate the discharge of filtered gas from the support frame.
[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model features a demisting mechanism installed on the upper end of a support frame. A hydraulic telescopic arm extends, causing a motor to move downwards. As the motor moves downwards, it drives a sealing block downwards until the airflow holes are closed. Simultaneously, the lower end of each set of impact plates comes into contact with the upper surface of the wire mesh demister. The motor is then activated, causing each set of impact plates to rotate and sequentially contact each set of top blocks. This causes each set of impact plates to move upwards and stretch the connected springs. When each set of impact plates detaches from the top blocks, the stretched springs rebound, causing each set of impact plates to instantly reset and impact the upper surface of the wire mesh demister. This causes the wire mesh demister to vibrate, thus solving the problem in the prior art where previously separated microparticles (such as rust and polymer colloids) re-enter the oil phase, reducing product quality.
[0012] 2. This utility model uses a scraping mechanism installed in the collection box. When the motor is started, the scraper rotates in the slide rail via a telescopic rod. At this time, the scraper rotates in contact with the surface of the collection box and scrapes away the stains on the surface of the collection box until the stains are moved to the drain pipe. The stains will then fall into the storage box through the drain pipe, which can effectively collect the stains in the collection box and prevent the stains from accumulating in the collection box.

[0016] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.
[0017] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.
[0018] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.
[0019] Please see Figures 1 to 5 As shown, this utility model provides an oil and gas recovery and separation device, including an oil storage tank 1 for storing oil. A support frame 2 is provided at the upper end of the oil storage tank 1. A collection frame 3 is provided in the support frame 2. An airflow hole 4 is provided on the collection frame 3 to allow the gas to flow to a wire mesh demister 5. A wire mesh demister 5 is provided inside the support frame 2 and above the collection frame 3 to separate the mist contained in the gas. Multiple sets of top blocks 7 are provided at the upper end of the wire mesh demister 5 to allow the impact plate 605 to move upward. The upper end of each set of top blocks 7 is in a smooth arc shape to reduce the friction generated when in contact with the impact plate 605.
[0020] Among them, the upper end of the support frame 2 is equipped with a defoaming mechanism 6; The hydraulic telescopic arm 601 in the demisting mechanism 6 extends, causing the motor 602 in the demisting mechanism 6 to move downward. When the motor 602 moves downward, it drives each set of impact plates 605 and sealing blocks 603 in the demisting mechanism 6 to move downward until the lower end of the impact plate 605 moves to fit against the upper end of the wire mesh demister 5, and at the same time until the sealing block 603 moves to the airflow hole 4 and closes it. This is to prevent dirt falling from the wire mesh demister 5 from falling into the airflow hole 4.
[0021] When the motor 602 shaft rotates, it drives each set of support plates 604 in the demister mechanism 6 to rotate. When each set of support plates 604 rotates, it drives the lower end of each set of impact plates 605 to rotate against the upper surface of the wire mesh demister 5. After each set of impact plates 605 rotates and contacts each set of top blocks 7 in sequence, it causes each set of impact plates 605 to move upward and stretch each set of springs 606 in the demister mechanism 6. After each set of impact plates 605 disengages from each set of top blocks 7, each set of springs 606 rebounds, causing each set of impact plates 605 to instantly reset and impact the wire mesh demister 5, causing the wire mesh demister 5 to vibrate. It is used to ensure that after each set of impact plates 605 detaches from the top block 7, each set of stretched springs 606 rebounds, causing each set of impact plates 605 to instantly reset and impact the upper surface of the wire mesh demister 5, thereby causing the wire mesh demister 5 to vibrate. It can effectively store elastic potential energy through the energy storage stage of the springs 606. When released instantaneously, the peak acceleration of the impact plates 605 can reach tens of times the acceleration of gravity, forming a high impact kinetic energy similar to the "hammering effect", which effectively destroys the adhesion between stubborn dirt and the wire mesh (such as electrostatic adsorption and condensation adhesion).
[0022] A scraping mechanism 8 is provided on the collection frame 3. When the shaft of the motor 602 rotates, it drives the telescopic rod 801 in the scraping mechanism 8 to rotate. When the telescopic rod 801 rotates, it drives the scraper 803 in the scraping mechanism 8, which is completely in line with the shape of the collection frame 3, to rotate. This is to facilitate complete contact with the surface of the collection frame 3. When the scraper 803 rotates in contact with the surface of the collection frame 3 and passes through the drain pipe 804, it moves the dirt on the surface of the collection frame 3 into the drain pipe 804. The inclined drain pipe 804 causes the dirt to move downward until it falls into the collection box 805 in the scraping mechanism 8. It is used to collect stains in the collection box 3 in a concentrated manner, so as to prevent stains from accumulating in the collection box 3.
[0023] The demisting mechanism 6 includes a hydraulic telescopic arm 601, a motor 602, a sealing block 603, a support plate 604, an impact plate 605, and a spring 606. The upper end of the support frame 2 is equipped with a hydraulic telescopic arm 601, which controls the vertical movement of the motor 602. The telescopic end of the hydraulic telescopic arm 601 is equipped with a motor 602, which rotates each set of support plates 604. The shaft of the motor 602 extends into the support frame 2 and passes through the wire mesh demister 5. A sealing block 603 is rotatably installed at the end of the motor 602 shaft located below the wire mesh demister 5. This sealing block 603 closes the airflow holes 4 during cleaning of the wire mesh demister 5, preventing dirt from falling into the airflow holes 4. Multiple sets of support plates 604 are installed on the section of the motor 602 shaft located above the wire mesh demister 5 and inside the support frame 2. Each set of support plates 604 has vertical... An impact plate 605 is slidably installed, which is used to instantly impact the surface of the wire mesh demister 5 to generate vibration, thereby shaking and cleaning the dirt on the wire mesh demister 5. Each set of impact plates 605 is connected to the supporting arm by a spring 606. The spring 606 stores energy in the impact plate 605 through tension, and then the spring 606 rebounds to make the impact plate 605 instantly reset and impact the wire mesh demister 5. The lower end of each set of impact plates 605 is smooth arc-shaped. The smooth arc surface makes the contact between the impact plate 605 and the wire mesh demister 5 more uniform, avoiding local high pressure points caused by sharp corners or irregular shapes. This uniform pressure distribution helps to reduce cutting, scratching and excessive stretching of the wire mesh material, thereby extending the service life of the wire mesh.
[0024] The scraping mechanism 8 includes a telescopic rod 801, a slide rail 802, a scraper 803, a drain pipe 804, and a collection box 805. An annular slide rail 802 is provided on the side wall of the collection frame 3 to ensure the stability of the scraper 803 during rotation. The scraper 803 is installed inside the slide rail 802 to adhere to the surface of the collection frame 3, thereby scraping and cleaning the dirt on the surface of the collection frame 3. A telescopic rod 801 is provided at the upper end of the scraper 803 to accommodate the motor 602. The shaft moves vertically back and forth. The end of the telescopic rod 801 away from the scraper 803 is connected to the shaft of the motor 602. The collection frame 3 is equipped with the same drain pipe 804, which is used to discharge the dirt scraped by the scraper 803 into the collection frame 3, thereby avoiding the accumulation of dirt in the collection frame 3. The drain end of the drain pipe 804 extends out of the support frame 2. A storage box 805 is provided on the outer wall of the oil storage tank 1 and below the drain pipe 804, which is used to collect the dirt in a centralized manner.
[0025] The upper end of the support frame 2 is provided with an exhaust pipe 9, which is used to discharge gas from the support frame 2. The upper end of the oil storage tank 1 is provided with an oil inlet 10, which is used to add oil to the oil storage tank 1.
[0026] Working principle: When the wire mesh demister 5 needs to be cleaned, the hydraulic telescopic arm 601 first extends, causing the motor 602 to move downward. When the motor 602 moves downward, it drives the sealing block 603 to move downward until the airflow hole 4 is closed. At the same time, when the motor 602 moves downward, it drives each set of support plates 604 to move downward. When each set of support plates 604 moves downward, it drives the impact plate 605 to move downward until the lower end of each set of impact plates 605 is in contact with the upper surface of the wire mesh demister 5. Next, the motor 602 is started to make each set of support plates 604 rotate. When each set of support plates 604 rotates, it drives the impact plate 605 to rotate and contact each set of top blocks 7 in turn. This causes each set of impact plates 605 to move upward and stretch the connected spring 606. When each set of impact plates 605 is separated from the top block 7, the stretched spring 606 rebounds and causes each set of impact plates 605 to instantly reset and impact the upper surface of the wire mesh demister 5, thereby causing the wire mesh demister 5 to vibrate. When the motor 602 starts, the telescopic rod 801 drives the scraper 803 to rotate in the slide rail 802. At this time, the scraper 803 rotates against the surface of the collection frame 3 and scrapes off the stains on the surface of the collection frame 3 until the stains are moved to the drain pipe 804. At this time, the stains will fall into the storage box 805 through the drain pipe 804.
