Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of chemical equipment, and specifically to a distillation kettle gas-liquid separation device. BACKGROUND

[0002] In the chemical production process, distillation is a common method of separating mixtures. Distillation kettle is the key equipment in the distillation process, which heats the mixture to boiling, evaporates the components with different boiling points, and then condenses the steam into liquid through the condensing system to achieve separation. In the distillation process, the efficiency of gas-liquid separation directly affects the distillation effect and product quality. Traditional distillation kettle usually uses simple baffle or gravity settling method to realize gas-liquid separation, but these methods have low separation efficiency and are easy to cause product loss and equipment blockage. SUMMARY

[0003] The utility model aims at providing a distillation kettle gas-liquid separation device to solve the problems raised in the background technology.

[0004] To achieve the above purpose, the utility model provides the following technical scheme: a distillation kettle gas-liquid separation device mainly consists of a separation tank body, which is carefully designed with multiple separation plates inside. Multiple through holes are evenly distributed on these separation plates to facilitate the separation of gas-liquid two-phase.

[0005] On the upper side of the separation tank body, we set the gas inlet and gas outlet to facilitate the smooth entry of the steam generated by the distillation kettle and the discharge of the separated gas. At the same time, we design the liquid outlet at the lower side of the separation tank body for the discharge of the separated liquid.

[0006] In order to further process the separated gas, the gas outlet is connected with a condensing tank, and a spiral condensing pipe is installed inside the condensing tank to promote the condensation process of the gas.

[0007] Inside the separation tank body, we also add a heating pipe to provide the necessary heat and ensure the smooth progress of the separation process. In addition, the lower end of the separation tank body is equipped with a support frame, which is provided with a vacuum pump and an air compressor, both of which are connected with the inside of the separation tank body to facilitate the adjustment of the pressure and temperature in the tank.

[0008] In order to accurately control the separation process, the separation tank body is also equipped with temperature sensor and pressure sensor, which can monitor and feedback the temperature and pressure conditions in the tank in real time.

[0009] In terms of structural design, the separation tank body can be cylindrical or conical, which helps to improve the separation efficiency and stability of the equipment.

[0010] Regarding the design of the through holes, they can be circular holes, elliptical holes or rectangular holes, and the edges of the through holes can be smooth or jagged, which can increase the contact area of the gas-liquid two-phase, thereby improving the separation efficiency.

[0011] In order to better control the liquid discharge in the condensing tank, an electromagnetic valve is arranged on the liquid outlet of the condensing tank, and the discharge amount of the liquid can be accurately adjusted through the control of the electromagnetic valve.

[0012] Compared with the prior art, the beneficial effects of the utility model are that: by arranging multiple separation plates in the separation tank body and multiple through holes on the separation plates, the gas-liquid contact area can be increased, thereby improving the efficiency of gas-liquid separation.

[0013] The temperature sensor and the pressure sensor arranged in the separation tank body can monitor and control the temperature and pressure in the separation process in real time, ensuring that the separation process is carried out under the best conditions.

[0014] By connecting the condensing tank and the spiral condensing pipe, the separated gas can be effectively condensed, further improving the separation efficiency and purity.

[0015] The lower end of the separation tank body is provided with a support frame, and the support frame is provided with a vacuum pump and an air compressor, which can flexibly adjust the vacuum degree in the separation tank body and adapt to the separation requirements of different materials.

[0016] The separation tank body is designed as a cylinder or a cone, which can reduce the space occupation and make the whole device more compact.

[0017] The smooth or jagged edge design of the through hole can reduce the resistance of the liquid passing through, while increasing the contact area of the liquid and the gas, further improving the separation efficiency.

[0018] The electromagnetic valve arranged on the liquid outlet of the condensing tank can realize automatic control of liquid discharge, improving the convenience and safety of operation. BRIEF DESCRIPTION OF DRAWINGS
