Description

Technical Field

[0001] The utility model relates to the technical field of esterification reaction devices, in particular to a water separator for esterification reaction. Background Art

[0002] The esterification reaction refers to the reaction of an alcohol with a carboxylic acid (or an oxygen-containing inorganic acid) under the action of a catalyst to form an ester and water. The remaining mixed liquid after the esterification reaction contains not only water but also an organic solvent used to remove water from the reaction system. Currently, the water separator requires manual drainage of the generated water from the water separator, and the operation process is cumbersome.

[0003] In view of the above problems, the patent document with the authorization announcement number CN218854250U discloses a water separator device for esterification reaction. The device is provided with a liquid level bucket connected to a water separation container, and a floating ball device is arranged on the liquid level bucket. The density of the floating ball device is greater than the density of the first liquid and less than the density of water. A travel tube corresponding to a limiting rod is arranged on the liquid level bucket, and a first magnetic control switch corresponding to a magnet is arranged on the travel tube. The first magnetic control switch and a water outlet valve located at the water outlet are electrically connected to a controller. The position of the density ball is automatically controlled according to the water layer of the water separator, and then a signal is sent by the magnetic control switch to control the opening of the water outlet valve to achieve automatic water separation in the esterification reaction.

[0004] However, although the above device can realize the automatic separation of water and the water-carrying agent, its structural form is complex, making its maintenance and cleaning processes more complicated. It is easy to leave impurities in the water separation container, affecting the service life of the water separation container. Moreover, it only has a water outlet at the bottom, and the separated water and residual impurities are discharged together through the water outlet, unable to realize the secondary utilization of the separated water, resulting in poor environmental protection. Summary of the Utility Model

[0005] The utility model provides a water separator for esterification reaction to solve the technical problems in the prior art that the complex structural form of the water separator leads to complicated maintenance and cleaning processes, and the poor environmental protection due to the inability to secondary utilize the separated water.

[0006] To solve the above problems, the water separator for esterification reaction provided by the utility model adopts the following technical solutions:

[0007] A water separator for esterification reaction, comprising:

[0008] A water separator main body, which includes a tank body extending vertically, and a head is rotatably installed at the top of the tank body;

[0009] A liquid inlet is opened at the top of the head, and the liquid inlet is used to connect with the liquid discharge port of the condenser. A water outlet and a liquid outlet are opened at the side of the tank body, and a drain port is opened at its bottom;

[0010] The opening height of the liquid outlet is greater than that of the water outlet;

[0012] Valves are provided at the drain port, the water outlet and the liquid outlet.

[0013] The beneficial effects of the esterification reaction water separator provided by the present utility model are as follows:

[0014] 1. By providing a main body of the water separator including a head and a tank body, and rotatably connecting the head to the tank body, there are few components contained in the tank body.

[0015] 2. By providing a liquid inlet on the head, a water outlet and a liquid outlet on the side of the tank body, a drain port at the bottom thereof, and making the opening height of the liquid outlet greater than that of the water outlet. Since the density of the organic solvent is less than that of water, after the two are statically separated, water will sink to the bottom of the tank body, and the organic solvent is located above the water. The separated organic solvent is discharged from the liquid outlet, and water flows to the water outlet through the water outlet pipe under the action of the liquid level difference and is finally discharged from the water outlet. The water mixed with impurities is located at the bottom of the tank body and is discharged through the drain port, realizing the separation and classified recovery of the organic solvent, water and impurities. The organic solvent and the water discharged from the water outlet can be reused, thereby improving its environmental protection performance.

[0016] In summary, the structure of the present utility model is simple, the number of components to be cleaned is small, it is convenient to quickly clean the inside of the tank body, and the separation of the organic solvent, water and impurities is realized, so that the secondary utilization of the organic solvent and water can be achieved, effectively solving the technical problems in the prior art that the structure of the water separator is complex, resulting in a complex maintenance and cleaning process, and the poor environmental protection performance due to the inability to reuse the separated water.

[0017] Further, flange plates are correspondingly provided at the connection part of the head and the tank body. A plurality of clamp bolts are provided on the flange plates. The clamp bolts include two clamp bodies that cooperate up and down and a bolt passing through the clamp bodies. A nut is screwed on the bolt to adjust the distance between the two clamp bodies by the screwing position of the nut on the bolt, thereby realizing the fixation between the two flange plates.

[0018] Further, a plurality of the clamp bolts are circumferentially and evenly distributed along the outer circumference of the head.

[0019] Further, the water outlet and the liquid outlet are respectively opened on two opposite sides of the tank body.

[0020] Further, a drain pipe and a liquid outlet pipe are respectively connected to the drain port and the liquid outlet port.
