Description

Technical Field

[0001] The utility model relates to the technical field of chemical engineering, in particular to a device for balancing the internal pressure of equipment. Background Art

[0002] In chemical processes, some products are often synthesized through reactors. When these products reach a certain boiling point, the gases of the desired products are generated and discharged from the reactor through pipelines.

[0003] However, it still has the following disadvantages in actual use:

[0004] Under the existing technology, in areas with high altitudes, due to the decrease in atmospheric pressure, the boiling point of the reaction materials is reduced, resulting in a decrease in the boiling point of the gas products in the synthesis reaction. The tail gas from the synthesis reactor is directly discharged, and the gas components in the reaction materials that have not completely reacted may not be fully utilized, thereby reducing the conversion rate of the system.

[0005] Therefore, a device for balancing the internal pressure of equipment is provided to solve the above problems. Utility Model Content

[0006] The utility model provides a device for balancing the internal pressure of equipment, comprising:

[0007] The main body assembly includes a first air inlet pipe and a second air inlet pipe;

[0008] A pressure balance assembly, comprising a second solenoid valve connected to the first air intake pipe, a third air intake pipe connected to the first air intake pipe, a third solenoid valve connected to the second air intake pipe, a fourth air intake pipe connected to the second air intake pipe, a sealing tank connected to the third air intake pipe and the fourth air intake pipe, an exhaust pipe connected to the sealing tank, a first solenoid valve connected to the exhaust pipe, and a liquid discharge pipe connected below the sealing tank;

[0009] The uniform component includes a circulation pump fixed to the outer surface of the top of the sealed tank by screws, a liquid extraction pipe connected to the circulation pump, a liquid outlet pipe connected to the circulation pump, and a delivery pipeline connected to the other end of the liquid outlet pipe. The lower end of the liquid extraction pipe is located below the liquid level of the reaction solvent in the sealed tank, and the delivery pipeline is fixed to the top surface of the sealed tank by screws.

[0010] Furthermore, the first air inlet pipe is connected to the exhaust pipe, and the second air inlet pipe is connected to the exhaust pipe. The gas discharged from the first reactor can be directly transported to the exhaust pipe through the first air inlet pipe, and the gas discharged from the second reactor can be directly transported to the exhaust pipe through the second air inlet pipe.

[0011] Furthermore, the main assembly further includes a first reactor connected to the other end of the first air inlet pipe and a second reactor connected to the other end of the second air inlet pipe.

[0012] Furthermore, the reaction solvent in the sealed tank is the same as the reaction solvent in the first reactor and the second reactor. The sealed tank is used to store the reaction solvent, and the reaction solvent in the first reactor, the second reactor and the sealed tank is the same to ensure that the tail gas can fully react.

[0013] Furthermore, the uniform component also includes a nozzle connected to the delivery pipeline, and the nozzles are in a total of several groups, evenly distributed on the delivery pipeline. The nozzles can make the liquid spray evenly from the top of the tank downward, so that the contact area between the liquid and the gas is increased.

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] 1. The utility model forms a liquid sealing device by setting a pressure balance component and cooperating with the same reaction solvent as that in the reactor. Through liquid sealing, the seal is formed by using liquid, which can maintain the pressure balance of the system and improve the conversion rate of the system.

[0016] Second, the device balances the impact of high altitude on the synthesis reaction through the adjustment of liquid injection. It can even conduct some micro-positive pressure reactions through liquid injection adjustment. The liquid seal uses the reaction solvent to avoid the impact of backflow caused by human operating errors on the reaction.
