Description

Technical Field

[0001] The utility model relates to the technical field of production and processing of concentrated evaporators, in particular to a concentrated evaporator that can effectively reduce the loss of organic solvents. Background Technique

[0002] A concentrated evaporator is a device that concentrates a liquid using the evaporation principle. Its principle is to utilize the boiling point difference between the solute and the solvent. By heating, the solvent is evaporated, and then the steam is condensed to obtain a concentrated solution and pure solvent.

[0003] When the existing evaporator is in use, due to the high volatility of organic solvents, during the evaporation process, the solvent is easily volatilized by heat and flows out of the system along with the steam, resulting in loss. When the heating tank heats the solution, the temperature fluctuates continuously, causing improper control of the vacuum degree inside the tank body. Moreover, the existing condensation system uses a single-tube condenser, and the contact surface with the steam is small, unable to condense the steam into liquid in time, resulting in a large loss of organic solvents.

[0004] The reason for this problem is that the raw material liquid is transported into the heating tank body through a conduit. After heating is completed, the steam enters the evaporation tube along the conduit, and the raw material liquid is supplemented into the heating tank along the conduit, causing the temperature inside the tank body to decrease. To heat the raw material liquid, the heating plate has to be in a heating state all the time, resulting in overheating of the raw material liquid, leading to too low or too high vacuum degree inside the tank body. The solvent is easily volatilized by heat and flows out of the system along with the steam, resulting in loss. In addition, the single condenser in the condensation system has poor instantaneous condensation effect on a large amount of steam, which will cause most of the organic solvents to be discharged from the tank body as a whole, resulting in a large loss of organic solvents. Therefore, aiming at the deficiencies of the existing technology, we propose a concentrated evaporator that can effectively reduce the loss of organic solvents to solve the above problems. Content of the Utility Model

When the heating tank heats the solution, the temperature fluctuates continuously, causing improper control of the vacuum degree inside the tank body. Moreover, the existing condensation system uses a single-tube condenser, and the contact surface with the steam is small, unable to condense the steam into liquid in time, resulting in a large loss of organic solvents.

[0006] To achieve the above purposes, the utility model is realized through the following technical solutions: A concentrated evaporator that can effectively reduce the loss of organic solvents, including an evaporator, which is composed of a heating tank, an evaporation tank, and a condensation tank. A loss reduction mechanism is arranged at one end of the evaporator, and the loss reduction mechanism includes a raw material tank, a first steam pipe, a second steam pipe, and a heat conduction pipe;

[0007] The heat conduction pipe is fixedly connected inside the raw material tank. The two ends of the heat conduction pipe are respectively connected to the first steam pipe and the second steam pipe. The other end of the first steam pipe is fixedly connected to the evaporation tank, and the second steam pipe is fixedly connected to the condensation tank;

[0008] A plurality of condenser pipes are fixedly connected inside the condensation tank.

[0010] Preferably, a water inlet pipe is fixedly connected to the other end of the first adapter, and a water outlet pipe is fixedly connected to the other end of the second adapter.

[0012] Preferably, a fan is fixedly connected to one side of the heat dissipation box.

[0013] Preferably, a water tank is arranged at one end of the condensation tank, and the other ends of the water inlet pipe and the water outlet pipe are fixedly connected to the water tank.

[0014] The present utility model discloses a concentration evaporator that can effectively reduce the loss of organic solvents, and the beneficial effects thereof are as follows: By preheating the temperature of the organic solvent, the heating plate inside the heating tank can heat at a constant temperature, ensuring the vacuum degree inside the tank.

Apparently, the described embodiments are some but not all of the embodiments of the present utility model.

[0023] The embodiment of the present application provides a concentrated evaporator that effectively reduces the loss of organic solvents, solving the problems that in the existing evaporator during use, due to the high volatility of organic solvents, during the evaporation process, the solvent is easily volatilized by heat and flows out of the system with the steam, causing loss; when the heating tank heats the solution, the temperature fluctuates continuously, resulting in improper control of the vacuum degree inside the tank body; and the existing condensation system uses a single-tube condensation pipe, with a small contact area with the steam, and it is unable to condense the steam into a liquid in time, causing a large amount of loss of organic solvents.

[0024] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0025] The embodiment of the present utility model discloses a concentrated evaporator that effectively reduces the loss of organic solvents.

[0026] According to the attached Figures 1-5 As shown, it includes an evaporator 1, which is composed of a heating tank 101, an evaporation tank 102 and a condensation tank 103. A loss reduction mechanism 2 is provided at one end of the evaporator 1. The loss reduction mechanism 2 includes a raw material tank 201, a first steam pipe 202, a second steam pipe 203 and a heat conduction pipe 204;

[0027] When the device is in use, the raw material liquid is injected into the heating tank 101 through the raw material tank 201. After the raw material liquid is heated, it is sprayed into the evaporation tank 102 through a nozzle. The evaporation tank 102 heats the original liquid, so that the steam is discharged from the inside of the evaporation tank 102 along the first steam pipe 202 and enters the raw material tank 201. The heat conduction pipe 204 inside the raw material tank 201 is fixedly connected to the first steam pipe 202, so that the temperature of the original liquid is preheated. The steam enters the inside of the condensation tank 103 along the second steam pipe 203. Through the condensation of the double condensation pipe 205, the steam is instantaneously condensed, reducing the loss of the solvent and completing the concentration of the solvent. The original liquid that cannot be evaporated exists at the bottom of the evaporation tank 102. Through the valve port at the bottom of the evaporation tank 102, the discharge of the concentrated liquid is controlled. After the evaporation and purification of the original liquid are completed, the valve port is opened to obtain the concentrated liquid.

[0028] The heat conduction pipe 204 is fixedly connected inside the raw material tank 201. The two ends of the heat conduction pipe 204 are respectively connected to the first steam pipe 202 and the second steam pipe 203. The other end of the first steam pipe 202 is fixedly connected to the evaporation tank 102, and the second steam pipe 203 is fixedly connected to the condensation tank 103;

[0029] Multiple groups of condensation pipes 205 are fixedly connected inside the condensation tank 103.

[0030] One end of multiple groups of condensation pipes 205 is fixedly connected with a first adapter 206, the other end of multiple groups of condensation pipes 205 is fixedly connected with a second adapter 207, the other end of the first adapter 206 is fixedly connected with a water inlet pipe 208, and the other end of the second adapter 207 is fixedly connected with a water outlet pipe 209.

[0031] A heat dissipation box 210 is sleeved on the outer surface of the water outlet pipe 209. A heat conduction sheet 211 is fixedly connected inside the heat dissipation box 210. The inner wall of the heat conduction sheet 211 abuts against the outer surface of the water outlet pipe 209. A fan 212 is fixedly connected to one side of the heat dissipation box 210.

[0032] A water tank 213 is arranged at one end of the condensation tank 103. The water inlet pipe 208 and the other ends of the water outlet pipe 209 are fixedly connected to the water tank 213. Through the water pump on one side of the water tank 213, the coolant is injected into the first adapter 206 through the water inlet pipe 208. The coolant enters the inside of the condensation pipe 205 along the first adapter 206. The heated coolant enters the water outlet pipe 209 along the second adapter 207. When the coolant passes through the heat dissipation box 210, the heat conduction sheet 211 inside it discharges the temperature of the coolant, and the fan 212 cools the coolant, so that the coolant can always produce a cooling effect. When the steam enters, the hot gas reacts with the pipe wall, so that the water inside the steam falls along the condensation pipe 205 to the tank body, completing the condensation of the steam.

[0033] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments. The above-mentioned embodiments and the descriptions in the specification only illustrate the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
