Description

Technical Field

[0001] This utility model relates to the field of LDS system technology, and in particular to a gas extraction mechanism for LDS systems. Background Technology

[0002] LDS (Liquid, Gas, and Digester) supply systems are chemical material conveying systems that include the conveying of liquid and gas materials. When processing some chemicals that require high purity, it is necessary to separate the gas from the liquid to ensure the purity of the materials. This requires a gas-liquid separation mechanism to separate the gas and liquid. After gas-liquid separation, the liquid will be discharged through the drain pipe at the bottom of the gas-liquid separator, while the gas will be discharged through the exhaust pipe at the top of the gas-liquid separator, as shown below.

[0003] A search revealed a patent with authorization announcement number CN222489306U, which discloses a gas-liquid separation device for an LDS supply system. The device includes a gas-liquid separation tank, a motor at the bottom of which is fixedly connected to a limiting cylinder at the top of its output shaft. A rotating rod is mounted on the limiting cylinder, and a spiral fan blade is fixedly connected to the outside of the rotating rod. This gas-liquid separation device for an LDS supply system receives a gas-liquid mixture through a gas-liquid mixture inlet pipe into the gas-liquid separation tank. The motor drives the limiting cylinder, rotating rod, spiral fan blade, limiting rod, and scraper to rotate. The rotation of the spiral fan blade generates centrifugal force, separating the gas and liquid in the gas-liquid mixture. The liquid is thrown onto the inner wall of the gas-liquid separation tank, while the gas rises and is discharged through an exhaust pipe. The rotating scraper scrapes off the liquid adhering to the inner wall of the gas-liquid separation tank, and the liquid is discharged from the gas-liquid separation tank through a drain pipe, thus automatically cleaning the liquid from the inner wall.

[0004] However, the aforementioned gas-liquid separation device still has the following areas for improvement. For example, after gas-liquid separation, the gas is discharged through the exhaust pipe on its own, and the gas discharge speed is relatively slow. This makes it easy for the gas to mix with the liquid again when it stays in the gas-liquid separation tank, which reduces the purity of the liquid and affects the gas-liquid separation effect. Furthermore, the gas is not pre-purified during exhaust, and there are many harmful substances in the gas. If a leak occurs during subsequent processing, it is very likely to cause significant pollution to the surrounding environment and harm to personnel. Therefore, there is an urgent need for a gas extraction mechanism for LDS systems to solve the above technical problems. Utility Model Content

[0005] This utility model discloses a gas extraction mechanism for an LDS system. It incorporates a gas extraction and purification mechanism, allowing a gas-liquid mixture to be added to a gas-liquid separator tank via an inlet pipe during operation. The gas-liquid separator then separates the mixture, and the separated liquid is discharged through a drain pipe. Simultaneously, a fan operates, working in conjunction with the purification chamber, inlet pipe, and extraction pipe to generate negative pressure suction at two gas collection hoods. This suction quickly extracts the gas from the gas-liquid separator tank and transports it to the purification chamber. Inside the purification chamber, activated carbon filters adsorb and purify the gas, removing a large amount of harmful substances. Then, through the exhaust end of the exhaust fan and the external conveying pipe connected to the exhaust end, the purified exhaust gas is transported to the next treatment equipment for further treatment. Because the exhaust fan can extract the gas after gas-liquid separation from the gas-liquid separator in a timely and rapid manner, the gas is less likely to mix with the liquid material again, thereby effectively improving the purity of the liquid. It can also effectively adsorb, filter and purify a large number of harmful substances in the gas, thus effectively avoiding significant pollution to the surrounding environment and harm to personnel in the event of an accidental gas leak. In summary, the problems in the background technology are solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model discloses a gas extraction mechanism for an LDS system, including a base, a gas-liquid separator tank fixedly mounted on the top of the base, two drain pipes with valves at the bottom of the gas-liquid separator tank, a feed pipe on one side of the gas-liquid separator tank, and a gas-liquid separation mechanism inside and at the bottom of the gas-liquid separator tank.

[0008] The exhaust purification mechanism includes a mounting base, an exhaust fan, a purification box, and an exhaust pipe. The mounting base is fixedly installed on one side of the gas-liquid separator. The exhaust fan and the purification box are both fixedly installed on the top of the mounting base. The exhaust end of the exhaust fan is connected to one side of the purification box. An activated carbon filter plate is movably installed inside the purification box. An air inlet pipe is connected to the side of the purification box away from the exhaust fan. One end of the exhaust pipe is sealed to the air inlet pipe through a pipe connector. The other end of the exhaust pipe passes through the top of the gas-liquid separator and extends into the interior of the gas-liquid separator.

[0009] An electrostatic conductive mechanism is located inside the extraction pipe and at the pipe connection.

[0010] Furthermore, the other end of the extraction pipe consists of two branch pipes, the bottom ends of which both branch pipes penetrate the top of the gas-liquid separator. The bottom ends of the branch pipes are connected to a gas collection hood, and a waterproof and breathable membrane is fixedly connected inside the gas collection hood.

[0011] Furthermore, a door is hinged to one side of the purification box, and the door is sealed to the purification box when closed.

[0012] Furthermore, a support plate is fixedly connected to the bottom of the mounting base, and the bottom of the support plate is fixedly connected to the top of the base.

[0013] Furthermore, the electrostatic conductive mechanism includes a conductive mesh, connecting wires, bridging wires, grounding wires, and a grounding electrode. The conductive mesh is attached and fixed to the inner wall of the suction pipe, and the conductive mesh is connected to the pipe connector through the connecting wires. The two ends of the bridging wires are fixedly connected to the top and bottom of the pipe connectors, respectively. One end of the grounding wire is connected to the bridging wire, and the top of the grounding electrode is connected to the bottom end of the grounding wire.

[0014] Furthermore, both the exhaust pipe and the intake pipe are made of copper, and the pipe connectors are copper flange connectors.

[0015] The present invention has the following advantages over the prior art:

[0016] 1. This technical solution incorporates an exhaust purification mechanism. During operation, a gas-liquid mixture is added to the gas-liquid separation tank through the feed pipe. The gas-liquid separation mechanism then separates the mixture, and the separated liquid is discharged through the drain pipe. Simultaneously, the exhaust purification mechanism rapidly extracts the gas from the gas-liquid separation tank and transports it to a purification chamber. Inside the purification chamber, activated carbon filter plates adsorb and purify a large number of harmful substances in the gas. Finally, the purified exhaust gas is transported to the next processing equipment for further treatment via the exhaust fan's outlet and an external conveying pipe. Because the exhaust fan can quickly and promptly extract the separated gas from the gas-liquid separation tank, the gas is less likely to mix with the liquid, thus effectively improving the purity of the liquid. Furthermore, it effectively adsorbs, filters, and purifies a large number of harmful substances in the gas, thereby effectively preventing significant pollution and harm to personnel in the event of an accidental gas leak, greatly improving the practicality of the device.

[0017] 2. This technical solution incorporates an electrostatic conductivity mechanism, which guides the static electricity generated during gas transport and friction with the inner wall of the exhaust and intake pipes to the ground. This effectively releases static electricity inside the pipes, preventing excessive static electricity buildup that could lead to fire or explosion, thus improving the safety of the device.

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "surface", "side", "gap", "peripheral", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific Implementation Example 1:

[0028] Reference Figures 1-4 A gas extraction mechanism for an LDS system includes a base 1, a gas-liquid separator 2 fixedly mounted on the top of the base 1, two drain pipes 3 with valves at the bottom of the gas-liquid separator 2, a feed pipe 4 on one side of the gas-liquid separator 2, and a gas-liquid separation mechanism 5 inside and at the bottom of the gas-liquid separator 2.

[0029] The exhaust purification mechanism 6 includes a mounting base 601, an exhaust fan 602, a purification box 603, and an exhaust pipe 604. The mounting base 601 is fixedly installed on one side of the gas-liquid separator 2. The exhaust fan 602 and the purification box 603 are both fixedly installed on the top of the mounting base 601. The exhaust end of the exhaust fan 602 is connected to one side of the purification box 603. An activated carbon filter plate 605 is movably installed inside the purification box 603. An air inlet pipe 606 is connected to the side of the purification box 603 away from the exhaust fan 602. One end of the exhaust pipe 604 is sealed to the air inlet pipe 606 through a pipe connector 607. The other end of the exhaust pipe 604 passes through the top of the gas-liquid separator 2 and extends into the interior of the gas-liquid separator 2. The electrostatic conductivity mechanism 7 is located inside the exhaust pipe 604 and at the pipe connector 607.

[0030] The other end of the exhaust pipe 604 consists of two branch pipes 608. The bottom ends of the two branch pipes 608 penetrate the top of the gas-liquid separator 2. The bottom ends of the branch pipes 608 are connected to the gas collection hood 609. A waterproof and breathable membrane 610 is fixedly connected inside the gas collection hood 609. A door 611 is hinged to one side of the purification box 603. When the door 611 is closed, it is sealed to the purification box 603. A support plate 612 is fixedly connected to the bottom of the mounting base 601. The bottom of the support plate 612 is fixedly connected to the top of the base 1.

[0031] In the specific implementation process, during operation, the gas-liquid mixture can be added to the gas-liquid separator 2 through the feed pipe 4, and the gas-liquid mixture is separated by the gas-liquid separation mechanism 5. The liquid after gas-liquid separation is discharged through the drain pipe 3. At the same time, the exhaust fan 602 works in conjunction with the purification box 603, the air inlet pipe 606, and the exhaust pipe 604 to generate negative pressure suction at the two gas collection hoods 609, which helps to quickly extract the gas from the gas-liquid separator 2 and transport it to the purification box 603. The activated carbon filter plate 605 inside the purification box 603 adsorbs and purifies a large number of harmful substances in the gas. Finally, through the exhaust end of the exhaust fan 602 and the external conveying pipe connected to its exhaust end, the purified exhaust gas is transported to the next treatment equipment for further treatment. Since the exhaust fan 602 can extract the gas after gas-liquid separation from the gas-liquid separator 2 in a timely and rapid manner, the gas is not easy to mix with the liquid material again, thereby effectively improving the purity of the liquid. It can also effectively adsorb, filter and purify a large number of harmful substances in the gas, thereby effectively avoiding significant pollution to the surrounding environment and harm to personnel in the event of subsequent accidental gas leakage.

[0032] Among them, the two branch pipes 608 can work with the two gas collecting hoods 609 to draw gas from the gas-liquid separator 2 more evenly and widely, thereby improving the gas extraction and separation effect and efficiency.

[0033] The door 611 is provided to facilitate the replacement of the activated carbon filter plate 605. When the door 611 is closed, it is sealed to the purification box 603 to ensure the airtightness of the connection between the door 611 and the purification box 603 and to prevent exhaust gas leakage.

[0034] The support plate 612 can improve the stability of the mounting base 601, making it less prone to shaking. Specific Implementation Example 2:

[0036] Reference Figure 3 and Figure 5 In a preferred embodiment, the electrostatic conductivity mechanism 7 includes a conductive mesh 701, a connecting wire 702, a bridging wire 703, a grounding wire 704, and a grounding electrode 705. The conductive mesh 701 is attached and fixed to the inner wall of the suction pipe 604, and the conductive mesh 701 is connected to the pipe connector 607 through the connecting wire 702. The two ends of the bridging wire 703 are fixedly connected to the top and bottom of the pipe connector 607, respectively. One end of the grounding wire 704 is connected to the bridging wire 703, and the top of the grounding electrode 705 is connected to the bottom end of the grounding wire 704.

[0037] Both the exhaust pipe 604 and the intake pipe 606 are made of copper, and the pipe connector 607 is a copper flange connector.

[0038] In the specific implementation process, during operation, the conductive mesh 701, in conjunction with the connecting wire 702, pipe connector 607, jumper wire 703, grounding wire 704, and grounding electrode 705, can guide the static electricity generated in the exhaust pipe 604 and intake pipe 606 due to friction with the inner wall of the pipe during gas transportation to the ground, thereby effectively releasing the static electricity inside the pipe. This effectively prevents the accumulation of static electricity inside the pipe from causing fire or explosion, thus improving the safety of the device.

[0039] The extraction pipe 604 and the inlet pipe 606 are both made of copper, which ensures that the extraction pipe 604 and the inlet pipe 606 have good electrical conductivity and good corrosion resistance. The pipe connector 607 is a copper flange connector, which also ensures that the flange connector has good electrical conductivity and corrosion resistance.

[0040] Working Principle: During operation, a gas-liquid mixture is added to the gas-liquid separator 2 through the feed pipe 4. The gas-liquid separator 5 separates the mixture, and the separated liquid is discharged through the drain pipe 3. Simultaneously, the exhaust fan 602 works in conjunction with the purification chamber 603, the air inlet pipe 606, and the exhaust pipe 604 to generate negative pressure suction at the two gas collection hoods 609. This suction helps to quickly draw the gas away from the gas-liquid separator 2 and transport it to the purification chamber 603. Inside the purification chamber 603, the activated carbon filter plate 605 adsorbs and purifies the gas, removing a large amount of harmful substances. Finally, the exhaust gas after purification is transported to the next treatment equipment for further treatment through the exhaust end of the exhaust fan 602 and the external conveying pipe connected to the exhaust end. Since the exhaust fan 602 can extract the gas after gas-liquid separation from the gas-liquid separator 2 in a timely and rapid manner, the gas is not easy to mix with the liquid material again, thereby effectively improving the purity of the liquid. It can also effectively adsorb, filter and purify a large number of harmful substances in the gas, thereby effectively avoiding the large pollution and harm to personnel in the event of subsequent gas accidental leakage.

[0041] Furthermore, during operation, the conductive mesh 701 inside the extraction pipe 604, in conjunction with the connecting wire 702, pipe connector 607, jumper wire 703, grounding wire 704, and grounding electrode 705, can guide the static electricity generated in the extraction pipe 604 and intake pipe 606 due to friction with the inner wall of the pipe during gas transportation to the ground. This effectively releases the static electricity inside the pipe, thereby effectively preventing the accumulation of static electricity inside the pipe from causing fire or explosion, and improving the safety of the device.
