[0022] Specifically, the separator 100 is used to separate the material into water and ester substances, the deesterifier 200 is used to deesterify the ester substances, and the heat exchanger 300 is used to heat the deesterified substances; a material inlet 120 is provided at the bottom of the separator 100, and the waste liquid enters the pipeline from the main feed inlet 110, and then enters the separator 100 through the material inlet 120. A primary material outlet 130 is provided on one side of the separator 100. After the waste liquid is separated, the material flows out from the primary material outlet 130. The primary material outlet 130 is connected to the deesterification feed inlet 230 at the top of the deesterifier 200, and the material flows out from the primary material outlet 130 to the deesterifier 200. ; An ester discharge port 210 and a water outlet 220 are provided on one side of the deesterifier 200. The ester discharge port 210 is used to discharge ester substances, and the high brine produced by the material in the deesterifier 200 is discharged from the water outlet 220; the heat exchanger 300 is used to heat water, and the water outlet at the top of the heat exchanger 300 is connected to the material inlet 120 by a pipeline. Such an arrangement allows the hot water in the heat exchanger 300 to enter the separator 100 together with the waste liquid, and the water inlet at the bottom of the heat exchanger 300 is connected to the secondary material outlet 240 by a pipeline. Other substances obtained after the material is deesterified in the deesterifier 200 enter the heat exchanger 300 through the secondary material outlet 240, and then enter the separator 100 through the heat exchanger 300 for circulation.
[0023] In a possible implementation, the material outlet 130 is disposed at a height equal to the liquid level in the separator 100 .
[0024] Specifically, Figure 1 As shown, after the material is separated in the separator 100 , water and ester substances are obtained. In order to facilitate the ester substances to flow into the deesterifier 200 , the material outlet 130 on the separator 100 is set at a height equal to the liquid level in the separator 100 .
[0025] In a possible implementation, a central tube 250 is disposed in the deesterifier 200 , the top of the central tube 250 is connected to the deesterification feed port 230 , and the bottom of the central tube 250 is immersed under the liquid surface in the deesterifier 200 .
[0026] Specifically, Figure 1 As shown, the ester substance enters the deesterification feed port 230 through a pipeline, and the central tube 250 is connected to the deesterification feed port 230. The ester substance enters the deesterifier 200 through the central tube. In order to prevent the ester substance from falling directly from the top of the deesterifier 200 and impacting the ester substance layer in the deesterifier 200, the bottom of the central tube 250 is immersed under the liquid surface in the deesterifier 200, so that the ester substance flowing out of the separator 100 directly avoids the ester substance layer in the deesterifier 200.
[0027] In a possible implementation, the ester discharge port 210 is arranged at a height equal to the liquid level in the deesterifier 200 .
[0028] Specifically, Figure 1 As shown, in order to facilitate the discharge of the ester materials in the deesterifier 200 out of the device, the height of the ester discharge port 210 is set to be equal to the liquid level in the deesterifier 200.

[0030] Specifically, Figure 1 As shown, the deesterifier 200 also includes a gathering net 260. The ester substances continue to move downward into the gathering net 260 in the deesterifier 200. The gathering net 260 is composed of cross-shaped baffles commonly used in evaporative separators. Small particles of oil ester remaining in the water collide here to form large particles of oil ester and then float to the liquid surface, thereby increasing the extraction effect of ester substances.

[0032] Specifically, Figure 1 As shown, a circulation pump 400 is provided between the deesterifier 200 and the heat exchanger 300 in order to circulate the deesterified material from the deesterifier 200 to the heat exchanger 300 to start heating and ice circulation.
[0033] In one possible implementation, the separator 100 includes an inlet pipe, a defoaming component and a reflux circulation pipe, which are connected in sequence; the heat exchanger 300 includes a shell, a tube bundle, a tube sheet and a baffle, and a plurality of parallelly arranged tubes are placed in the tube bundle, and both ends of the tube bundle are fixedly connected to the shell through the tube sheet; and a salt leg is provided at the bottom of the separator 100.
[0034] Specifically, the separator 100 is used to separate the material into water and ester substances, and the function of the heat exchanger 300 is to heat the deesterified material; wherein the separator 100 can be a separator without a salt leg, and can also be a separator with a salt leg.
[0035] In a possible implementation, the internal material of the separator, the internal material of the deesterifier, and the internal material of the heat exchanger are all polytetrafluoroethylene.
[0036] Specifically, polytetrafluoroethylene is selected because metal materials are very susceptible to corrosion and ester substances are easily adhered to the metal pipe wall. The use of polytetrafluoroethylene solves the corrosion and adhesion problems.
[0037] When the present application is used, the waste liquid enters the pipeline from the main feed port 110, and then enters the separator 100 through the material liquid inlet 120 for separation. The separated ester substance flows into the deesterifier 200 through the primary material liquid outlet 130, and then the ester substance is directly transported to below the liquid surface in the deesterifier 200 through the central tube 250 for deesterification. After deesterification, an ester substance layer is obtained, and the ester substance layer is discharged from the device through the ester discharge port 210. The water obtained after deesterification enters the heat exchanger 300 for heating, and is circulated to the separator again after heating.
[0038] The present application sets a separator 100 for separating materials into water and ester substances, the deesterifier 200 is used to deesterify the ester substances, and the heat exchanger 300 is used to heat the deesterified substances; a material inlet 120 is set at the bottom of the separator 100, and the waste liquid enters the pipeline from the main feed inlet 110, and then enters the separator 100 through the material inlet 120. A primary material outlet 130 is set on one side of the separator 100. After the waste liquid is separated, the material flows out from the primary material outlet 130. The primary material outlet 130 is connected to the deesterification feed inlet 230 at the top of the deesterifier 200, and the material flows out from the primary material outlet 130 to the deesterifier 20 0; one side of the deesterifier 200 is provided with an ester discharge port 210 and a drain port 220, the ester discharge port 210 is used to discharge ester substances, and the high brine generated by the material in the deesterifier 200 is discharged from the drain port 220; the heat exchanger 300 is used to heat water, and the water outlet at the top of the heat exchanger 300 is connected to the material inlet 120 by a pipeline. Such a setting is that the hot water in the heat exchanger 300 enters the separator 100 together with the waste liquid, and the water inlet at the bottom of the heat exchanger 300 is connected to the secondary material outlet 240 by a pipeline. The other substances obtained after the material is deesterified in the deesterifier 200 enter the heat exchanger 300 through the secondary material outlet 240, and then enter the separator 100 through the heat exchanger 300 for circulation;
[0039] The primary material liquid outlet 130 is arranged at the liquid surface in the separator 100, and the ester discharge port 210 is arranged at the liquid surface in the deesterifier 200, so as to facilitate the discharge of the deesterified material; a central tube 250 is arranged, and the ester material flowing out of the separator 100 directly enters below the liquid surface in the deesterifier 200 through the central tube 250, and then the small particles of oil ester remaining in the water are collided here by the gathering net 260 to form large particles of oil ester and then float to the liquid surface, thereby increasing the extraction effect of the ester material; through the above arrangement, the present application reduces the water content by evaporation to increase the salt content, and finally increases the water density to complete the extraction of esters, thereby solving the problem that a large amount of salting-out agent must be added to achieve the effect of most of the ester material precipitation, which means that a large amount of cost needs to be invested.

In fact, the user can flexibly set various parameters according to personal preferences and / or actual application scenarios, as long as the design is reasonable.
