Description

Technical Field

[0001] This utility model relates to the field of gas-liquid separator technology, specifically to a gas-liquid separator. Background Technology

[0002] In chemical production, the non-condensable gases from each column of the distillation system, as well as the exhaust gases from each batching pump and reflux pump, need to be sent to an absorption tower for absorption using an absorbent. The unabsorbed tail gas is then continuously discharged to subsequent processes. However, the existing absorption towers have the problem of poor absorption efficiency, and the vent gas often carries absorbent and effective solutes. When the vent volume reaches the design limit, the entrainment of effective components becomes more severe, causing liquid accumulation in subsequent processes and potentially leading to significant safety and environmental hazards. Therefore, a gas-liquid separator is needed to recover the effective solutes from the non-condensable gases. However, traditional gas-liquid separators mostly use gravity separation. When the flow rate of the non-condensable gases containing effective solutes is too high, the gas-liquid separation becomes incomplete, affecting the separation effect. The solutes are carried away with the tail gas, increasing material loss and causing serious waste of effective solutes. Utility Model Content

[0003] The purpose of this invention is to provide a gas-liquid separator to solve the problem mentioned in the background art that when the non-condensable gas flow rate is too fast, the effective solute is not easily recovered and reused, resulting in waste.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a gas-liquid separator, comprising: 1. a gas-liquid separator, including a tank body, a top cover fixedly installed on the outer surface of the tank body, and an exhaust port fixedly installed on the outer surface of the top cover, the exhaust port and the top cover being concentrically designed; an air inlet pipe being installed through the side surface of the tank body; a sewage pipe being fixedly installed on the outer surface of the tank body, the sewage pipe being concentrically designed with the tank body; a liquid drain pipe being installed through the side surface of the tank body, the liquid drain pipe being L-shaped; an air inlet pipe being fixedly installed on the side surface of the tank body, the air inlet pipe being inclined; a baffle plate being fixedly installed on the outer surface of the top cover, the baffle plate being frustum-shaped; a deflector plate being fixedly installed on the outer surface of the top cover, the deflector plate being inverted frustum-shaped; and the deflector plate, the baffle plate, and the top cover being concentrically designed.

[0005] Preferably, an arc-shaped baffle is fixedly installed on the outer surface of the baffle, and the arc-shaped baffle is arranged around the exhaust port as the center. A baffle plate is fixedly installed on the outer surface of the deflector plate, and the baffle plate is tapered and located outside the baffle.

[0006] Using the above technical solution, after the non-condensable gas is injected between the shielding plate and the deflector plate, it will be blocked and guided again by the arc-shaped baffle, so that the non-condensable gas can move in the same direction to prolong its time in the temporal part of the tank and improve the separation effect of gaseous solvent and effective components.

[0007] Preferably, an anti-reverse wind baffle is fixedly installed inside the tank, and the anti-reverse wind baffle is a semi-circular design, and the anti-reverse wind baffle and the deflector plate are concentrically designed.

[0008] By adopting the above technical solution, the discharged non-condensable gas will continue to flow downward along the inclined surface of the baffle plate. At the same time, it can prevent the non-condensable gas and the gaseous solvent separated at the bottom from being carried away by the non-condensable gas and discharged from the exhaust port, thus reducing the probability of the gaseous solvent being carried out of the tank.

[0009] Preferably, a connector is inserted and installed on the outer surface of the tank, and the connector is located at the upper and lower ends of the tank. A clamping nut is slidably installed on the outer surface of the connector, and the clamping nut is tightly fitted to the outer surface of the connector. The clamping nut is threaded to the tank.

[0010] By adopting the above technical solution, the tank body and the connector can be easily connected and fixed, allowing for easy replacement of the connector when it becomes clogged or damaged.

[0011] Preferably, a glass tube is inserted and installed on the outer surface of the connector, and both ends of the glass tube are respectively attached to the outer surface of the connector. A sealing ring is provided between the connector and the glass tube. A through hole is opened inside the connector, and the glass tube is connected to the tank body.

[0012] By adopting the above technical solution, the connection between the installed glass tube, plug-in socket and tank body allows maintenance personnel to clearly see the volume of liquid separated inside the tank from the outside, and enables operators to have a clearer understanding of the tank's operation status during inspections.

[0013] Preferably, a magnetostrictive sensor is inserted and installed on the outer surface of the connector, and one end of the magnetostrictive sensor passes through the outer surface of the connector. A mounting nut is threaded onto the outer surface of one end of the magnetostrictive sensor, and the mounting nut is in close contact with the outer surface of the magnetostrictive sensor and the outer surface of the connector. A float is slidably mounted on the outer surface of the magnetostrictive sensor, and the float and the glass tube are concentrically designed. The outer surface of the glass tube is not in contact with the outer surface of the float, and a magnetic ring is fixedly mounted on the outer surface of the float.

[0014] By adopting the above technical solution, the connection between the plug and the glass tube can be made tighter through the installation of the magnetostrictive sensor and the mounting nut, reducing the probability of liquid leakage from the plug and the glass tube. At the same time, the float is set inside the glass tube, which can effectively prevent the up and down fluctuations caused by the non-condensable gas discharged from the air inlet pipe impacting the liquid phase in the tank, and can effectively improve the accuracy of the magnetostrictive sensor measurement.

[0015] Preferably, a first gate valve is fixedly installed on the outer surface of the sewage pipe, and a second gate valve is fixedly installed on the outer surface of the liquid discharge pipe.

[0016] By adopting the above technical solution, the independent setting of the first gate valve and the drain pipe, and the second gate valve and the liquid discharge pipe, can strictly distinguish between the "clean liquid phase to be recovered" and the "impurity phase to be discharged": when discharging liquid, only the second gate valve is opened to ensure that the recovered liquid phase is not contaminated by impurities in the drain pipe, thereby improving the purity of material recovery; when discharging wastewater, only the first gate valve is opened to prevent impurities from entering the recovery system with the liquid phase. At the same time, with the detection of the magnetostrictive sensor, the first and second gate valves can be opened and closed automatically, blocking the risk of "impurities affecting absorption efficiency" from the source, reducing material loss, improving the recovery effect, and enabling automated operation to prevent excessive release of liquid phase, which would cause non-condensable gases to be discharged from the liquid discharge pipe.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the gas-liquid separator:

[0018] 1. When non-condensable gas enters the tank through the inclined inlet pipe, it will first come into contact with the deflector plate and be blown back to the outer surface of the baffle plate. The arc-shaped baffle plate on the outer surface of the baffle plate intercepts and guides the blown non-condensable gas, allowing it to enter the lower end of the tank along the anti-backflow baffle plate. This allows the non-condensable gas to remain in the tank for a longer time and separate the entrained effective solute, thus improving the quality and effect of separating the effective solute.

[0019] 2. By tightening the plug-in base and the clamping nut to the tank body, the plug-in base can be easily installed and fixed. The use of the magnetostrictive sensor and the mounting nut makes the connection between the plug-in base and the glass tube tighter, improving the convenience of cleaning and maintaining the glass tube, and ensuring the sealing between the plug-in base and the glass tube. This ensures convenient installation and maintenance while reducing the chance of effective solute leakage from the tank.

[0020] 3. The glass tube and magnetostrictive sensor are installed on the outside of the tank. As the effective solute in the tank rises, the liquid level in the glass tube also rises and falls accordingly. At the same time, the float can also monitor the rise and fall of the liquid level. The glass tube can effectively prevent the magnetostrictive sensor from being inaccurate due to liquid level fluctuations, which greatly improves the monitoring accuracy of the magnetostrictive sensor and realizes automatic detection of the liquid level in the tank, reducing the frequency of worker inspections.

[0028] 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.

[0029] Please see Figure 1-6 This utility model provides a technical solution: a gas-liquid separator, including a tank body 1, a top cover 2 fixedly installed on the outer surface of the tank body 1, and an exhaust port 9 fixedly installed on the outer surface of the top cover 2. The exhaust port 9 and the top cover 2 are concentrically designed. An air inlet pipe 3 is installed through the side surface of the tank body 1. A sewage pipe 10 is fixedly installed on the outer surface of the tank body 1, and the sewage pipe 10 is concentrically designed with the tank body 1. A liquid drain pipe 11 is installed through the side surface of the tank body 1, and the liquid drain pipe 11 is L-shaped. The air inlet pipe 3 is fixedly installed on the side surface of the tank body 1 and is inclined. A baffle plate 4 is fixedly installed on the outer surface of the top cover 2. Furthermore, the shielding plate 4 is a frustum-shaped design, and an arc-shaped baffle 7 is fixedly installed on the outer surface of the shielding plate 4. The arc-shaped baffle 7 is arranged around the exhaust port 9 as the center. An anti-reverse wind baffle 8 is fixedly installed inside the tank body 1. The anti-reverse wind baffle 8 is a semi-arc design, and the anti-reverse wind baffle 8 and the deflector plate 5 are concentrically designed. A shielding plate 6 is fixedly installed on the outer surface of the deflector plate 5. The shielding plate 6 is a conical design and is located outside the shielding plate 4. A deflector plate 5 is fixedly installed on the outer surface of the top cover 2. The deflector plate 5 is an inverted frustum-shaped design, and the deflector plate 5, the shielding plate 4, and the top cover 2 are concentrically designed.

[0030] Firstly, during use, non-condensable gas enters the interior of tank 1 through inlet pipe 3 and is blown towards deflector plate 5, baffle plate 4, and top cover 2. The baffle plate 4 allows the non-condensable gas to move between the baffle plate 4 and deflector plate 5, while the arc-shaped baffle plate 7 blocks and obstructs the non-condensable gas, reducing its velocity and prolonging its residence time inside tank 1. Simultaneously, the baffle plate 6 separates the non-condensable gas and prevents falling droplets from directly entering the deflector plate 5, allowing the droplets to better adhere to the outer surfaces of the baffle plate 4 and deflector plate 5. The air discharged along the arc-shaped baffle plate 7 will contact the anti-reverse wind baffle plate 8, allowing excess air to contact the inner wall of tank 1, further enabling the effective solute to contact and roll off. At the same time, it effectively prevents the air from carrying away the organic solute stored in tank 1 when it is discharged from exhaust port 9, and prevents it from dripping back into tank 1, thus improving the separation of effective solute and reducing waste caused by exhaust gas discharge.

[0031] A connector 12 is inserted and installed on the outer surface of the tank body 1. The connector 12 is located at the upper and lower ends of the tank body 1. A clamping nut 18 is slidably installed on the outer surface of the connector 12, and the clamping nut 18 is tightly fitted to the outer surface of the connector 12. The clamping nut 18 is threadedly connected to the tank body 1. A glass tube 13 is inserted and installed on the outer surface of the connector 12, and both ends of the glass tube 13 are respectively fitted to the outer surface of the connector 12. A sealing ring is provided between the connector 12 and the glass tube 13. A through hole is opened inside the connector 12, and the glass tube 13 communicates with the tank body 1. A magnetostrictive sensor 14 is inserted and installed on the outer surface of the connector 12, and one end of the magnetostrictive sensor 14 passes through the outer surface of the connector 12. A mounting nut 17 is threaded on the outer surface of one end of the magnetostrictive sensor 14, and the mounting nut 17 is in close contact with the outer surface of the magnetostrictive sensor 14 and the outer surface of the connector 12. A float 15 is slidably mounted on the outer surface of the magnetostrictive sensor 14, and the float 15 and the glass tube 13 are concentrically designed. The outer surface of the glass tube 13 is not in contact with the outer surface of the float 15, and a magnetic ring 16 is fixedly mounted on the outer surface of the float 15.

[0032] Secondly, the plug-in 12 and the clamping nut 18 are used together to allow the plug-in 12 to be quickly and easily installed on the side surface of the tank 1. After the magnetostrictive sensor 14 and the mounting nut 17 are installed and tightened, the glass tube 13 and the plug-in 12 are connected more tightly, reducing the risk of leakage after disassembly and maintenance. The liquid level in the tank 1 can be easily viewed through the glass tube 13, and the fluctuation of the liquid level caused by wind can be eliminated. The float 15 and the magnetic ring 16 can move up and down stably, which greatly reduces the measurement error of the magnetostrictive sensor 14. The liquid level in the tank 1 can be directly viewed through the glass tube 13, which greatly improves the convenience of the separation tank installation and the accuracy of the measurement.

[0033] A first gate valve 19 is fixedly installed on the outer surface of the sewage pipe 10, and a second gate valve 20 is fixedly installed on the outer surface of the liquid drain pipe 11.

[0034] Furthermore, with the use of the magnetostrictive sensor 14, automated operation can be achieved, allowing the second gate valve 20 to be remotely controlled. With the detection of the magnetostrictive sensor 14, the opening degree of the second gate valve 20 can be adjusted at any time, so that the amount of effective solute discharged through the drain pipe 11 can be adjusted to ensure the pressure inside the tank 1. When sewage discharge is required, the first gate valve 19 is opened, so that effective solute containing impurities can be discharged from the sewage pipe 10, preventing impurities from flowing back into the recovery system through the drain pipe 11 due to excessive amounts, greatly improving the convenience of using the separator.

[0035] Working principle: As non-condensable gas enters the interior of tank 1 through inlet pipe 3, the inclined design of inlet pipe 3 allows the non-condensable gas to directly contact the deflector plate 5 and be blocked by the baffle plate 4, so that the non-condensable gas can move along the direction of the arc-shaped baffle plate 7 and slow down, allowing the effective solute in the non-condensable gas to be better separated. Then the gas directly impacts the anti-reverse wind baffle plate 8 and continues to move, continuing to contact the inner wall of tank 1, further removing the effective solute. Afterwards, the anti-reverse wind baffle plate 8 reduces the probability of the separated effective solute escaping from the exhaust port 9.

[0036] Secondly, as the effective solute liquid phase in tank 1 rises, the liquid level in glass tube 13 also rises, causing the float 15 and magnetic ring 16 to move together inside glass tube 13. This effectively reduces the inaccuracy of the magnetostrictive sensor 14 caused by the fluctuation of the liquid phase in tank 1, allowing the drain pipe 11 and drain pipe 10 to accurately discharge the required amount of liquid, reducing the probability of non-condensable liquid being discharged from drain pipe 11.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
