Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas-liquid separation technology, and in particular to a gas-liquid separation device for the recycling of furanyl dicarboxylic acid solvent. Background Technology
[0002] Furan dicarboxylic acid is a chemical raw material extracted from natural raw materials such as plant straw and fructose. It is often used to produce biodegradable plastics, which can reduce the pollution caused by traditional plastics. It is difficult to dissolve in water at room temperature, but it will slowly dissolve when heated to above 80 degrees Celsius. Therefore, hot water is often used to purify it. After cooling, it will crystallize and precipitate. It dissolves well in organic solvents such as alcohol. These solvents are often used to complete chemical reactions, such as the synthesis of biodegradable plastics. When making biodegradable plastics, high-boiling-point solvents are required because the reaction temperature is high, the solvent will not easily evaporate, and it can also make the raw materials mix evenly, thus successfully synthesizing plastics.
[0003] In the prior art, when recycling furanyl dicarboxylic acid solvent, since it exists in the form of a liquid in the gas, a rotary separator is required for gas-liquid separation. Most gas-liquid separators have fixed air guide mechanisms, which cannot adjust the airflow separation time. When the gas contains a large amount of liquid, it is often not fully separated, affecting the working efficiency of the device. Therefore, in order to solve the above problems, this utility model proposes a gas-liquid separation device for the recycling of furanyl dicarboxylic acid solvent. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a gas-liquid separation device for the recycling of furanyl dicarboxylic acid solvent. By using a servo motor to drive the transmission mechanism, the angle of the air guide plate is adjusted to change the rotation time of the airflow, thereby fully separating the gas and liquid, improving the separation effect, enhancing the working efficiency of the device, and facilitating adaptation to different media, thus improving the applicability of the separation device.
[0005] This utility model provides the following technical solution: a gas-liquid separation device for the reuse of furanyl dicarboxylic acid solvent, comprising a separation tank, with a housing first fixedly installed on the left and right sides of the separation tank. A servo motor is fixedly installed at the bottom of the inner cavity of the housing first. A rotating shaft first is fixedly connected to the output shaft of the servo motor via a coupling. Three helical gears first are uniformly fixedly sleeved on the rotating shaft first. Helical gears second are meshed on the outer side of the helical gears first. A rotating shaft second is fixedly sleeved on the helical gear second. The rotating shaft second is movably sleeved with the inner cavity of the separation tank. A rubber sealing gasket is provided at the connection between the rotating shaft second and the inner cavity of the separation tank. A guide plate is fixedly installed at one end of the rotating shaft second located in the inner cavity of the separation tank. An exhaust pipe is fixedly sleeved at the top of the inner cavity of the separation tank. A baffle is fixedly installed at the bottom of the inner cavity of the separation tank. By adjusting the angle of the guide plate by the servo motor, the airflow rotation time is changed to achieve full separation, improve the separation effect, enhance the working efficiency of the device, and facilitate the separation of different media, thereby improving the applicability of the separation device.
[0006] Preferably, an air inlet pipe is fixedly installed on the left side of the separation tank, and a housing second is fixedly installed on the rear side of the air inlet pipe. An electric actuator is fixedly installed on the rear side of the inner cavity of the housing second. There are two electric actuators, which are symmetrically distributed on the left and right. A movable block is fixedly installed on the telescopic end of the electric actuator. The movable block is movably connected to the air inlet pipe. The telescopic end of the electric actuator drives the movable block to move forward, reducing the space of the air inlet pipe and thus increasing the flow velocity of the airflow. This avoids the gas from failing to settle effectively due to insufficient inertial force.
[0007] Preferably, a humidity sensor is fixedly installed on the upper part of the air inlet pipe, and three probes are evenly fixedly installed on the bottom of the humidity sensor. The probes are fixedly sleeved on the upper part of the inner cavity of the air inlet pipe and located to the left of the moving block. The humidity of the gas is detected in real time by the probes on the humidity sensor, so as to facilitate the adjustment of the separation mechanism, which is conducive to the device accurately matching the optimal gas flow rate and improving the separation efficiency of the device.
[0008] Preferably, a storage tank is fixedly installed at the bottom of the separator, and a valve is fixedly installed on the right side of the storage tank. During the gas rotation, the solvent carried is thrown onto the inner wall of the separator cavity. The solvent falls into the storage tank cavity from the gap between the separator cavity and the baffle. When a certain amount is collected, the solvent can be discharged by opening the valve.
[0009] Compared with the prior art, the present invention has the following beneficial effects:
[0010] 1. The transmission mechanism driven by the servo motor adjusts the angle of the air guide plate in the inner cavity of the separator, making the angle between the air guide plate and the horizontal line smaller. This increases the rotation time of the airflow in the inner cavity of the separator, allowing the gas and liquid in the airflow to be fully separated, improving the separation effect of the device, enhancing the working efficiency of the device, reducing the pressure of subsequent gas purification, and the separator can be adapted to different media by adjusting the air guide plate, thus improving the applicability of the separation device.
[0011] 2. The humidity of the gas is detected by the probe on the humidity sensor. When the humidity is high, the extension end of the electric actuator drives the moving block to move forward, reducing the space of the air inlet pipe and increasing the flow velocity of the airflow. This prevents the droplets from failing to settle effectively due to insufficient inertial force, which helps the device to accurately match the optimal gas flow rate and prevents separation failure caused by improper flow rate. The inlet flow rate can be controlled in the optimal range in real time, improving separation efficiency. The device has a simple structure, saves costs, and is easy to maintain later.

Gas containing furanyl dicarboxylic acid solvent is introduced into the air inlet pipe 12 to open the humidity sensor. Sensor 16 detects the humidity of the gas via probe 17. When the humidity is high, the telescopic end of electric actuator 14 drives moving block 15 forward, reducing the space of air inlet pipe 12 and increasing the flow velocity of the passing air. This prevents droplets from failing to settle effectively due to insufficient inertial force, which helps the device accurately match the optimal gas flow rate and prevents separation failure caused by improper flow rate. The inlet flow rate can be controlled in real time within the optimal range, improving separation efficiency. The device has a simple structure, saves costs, and is easy to maintain.

[0020] Working principle: Gas containing furanyl dicarboxylic acid solvent is introduced into the air inlet pipe 12. The humidity sensor 16 is turned on to detect the humidity of the gas through the probe 17. When the humidity is high, the extension end of the electric actuator 14 drives the moving block 15 to move forward, reducing the space of the air inlet pipe 12 and thus increasing the airflow velocity. At the same time, the servo motor 3 drives the rotating shaft 4 to rotate. The rotating shaft 4 drives the rotating shaft 7 to rotate through the meshing between the helical gear 5 and the helical gear 6.
