Description

Technical Field

[0001] This application belongs to the field of wastewater treatment, specifically a solution separation system. Background Technology

[0002] Wastewater treatment often involves various toxic substances that require closed-loop disposal. In practice, the high water content of these chemicals leads to excessively high treatment costs and discharge risks. This system was designed to reduce the volume of wastewater discharged. Furthermore, this system can be upgraded to provide a reference for other gas-liquid separation applications. Utility Model Content

[0003] The purpose of this application is to address the shortcomings of existing technologies by designing a solution separation system that reduces the weight of light wastewater through evaporation, thereby solving the problem of how to reduce the amount of wastewater discharged and treated.

[0004] To achieve the above objectives, the following technical solution is adopted: A solution separation system includes an evaporator, a heat exchange shell, a water inlet pipe, a heat exchange tube, a reflux pipe, and a discharge pipe. The outer wall of the water inlet pipe penetrates the heat exchange shell and is fixedly connected to the inner wall of the heat exchange shell. The outer wall of the heat exchange tube penetrates the heat exchange shell and is fixedly connected to the inner wall of the heat exchange shell. The outer wall of the water inlet pipe contacts the outer wall of the heat exchange tube. The discharge end of the water inlet pipe is fixedly connected to the feed end of the evaporator. The feed end of the heat exchange tube penetrates the evaporator and is fixedly connected to the upper outer wall of the evaporator. The middle part of the bottom end of the evaporator penetrates the water inlet pipe and is fixedly connected to the outer wall of the discharge pipe. The outer wall of the evaporator near the bottom end penetrates the evaporator and is fixedly connected to the outer wall of the reflux pipe. The end of the reflux pipe away from the evaporator penetrates the evaporator and is fixedly connected to the inner wall of the water inlet pipe. The interior of the reflux pipe communicates with the interior of the water inlet pipe.

[0005] Preferably, it includes a water pump, wherein the outlet end of the water pump is fixedly connected to the inlet end of the water inlet pipe.

[0006] Preferably, a second water pump is included, which is disposed between the two ends of the inlet pipe.

[0007] Preferably, an air pump is included, which is disposed between the two ends of the heat exchange tube.

[0008] Preferably, it includes an electrical control box, which is signal-connected to water pump one, water pump two, air pump, and evaporator.

[0009] Preferably, the heat exchange tube is located in a spiral-shaped region inside the heat exchange shell.

[0010] Preferably, the height of the discharge pipe is lower than the height of the return pipe.

[0011] Compared with the prior art, the beneficial effects of this application are: 1. This application uses an evaporator to evaporate light wastewater, thereby causing some of the water in the light wastewater to form water vapor and separate from the wastewater. This allows enterprises to send only the remaining, lighter, heavy wastewater for treatment, thus solving the problem of how to reduce the amount of wastewater discharged and treated.

[0012] 2. This application adopts a method of exchanging heat between the water vapor generated during the evaporation of light wastewater and the untreated light wastewater, so that the light wastewater already has a certain amount of heat before entering the evaporation zone, thereby reducing the resources required to evaporate the light wastewater.

[0014] The components include: 1. Evaporator; 2. Heat exchange shell; 3. Water inlet pipe; 4. Heat exchange tube; 5. Water pump one; 6. Water pump two; 7. Return pipe; 8. Discharge pipe; 9. Air pump; and 10. Electrical control box. Detailed Implementation

[0015] Reference Figures 1-3 A solution separation system includes an evaporator 1, a heat exchange shell 2, an inlet pipe 3, a heat exchange tube 4, a reflux pipe 7, and a discharge pipe 8. The outer wall of the inlet pipe 3 penetrates the heat exchange shell 2 and is fixedly connected to the inner wall of the heat exchange shell 2. The outer wall of the heat exchange tube 4 also penetrates the heat exchange shell 2 and is fixedly connected to the inner wall of the heat exchange shell 2. The outer wall of the inlet pipe 3 is in contact with the outer wall of the heat exchange tube 4. Through this contact, the heat from the heat exchange tube 4 is transferred to the inlet pipe 3 via heat conduction, and then the inlet pipe 3 heats the light wastewater inside the inlet pipe. The discharge end of the inlet pipe 3 is connected to the inlet of the evaporator 1. The feed end is fixedly connected. Evaporator 1 is used to evaporate light wastewater. The feed end of heat exchange tube 4 passes through and is fixedly connected to the upper outer wall of evaporator 1. The bottom middle of evaporator 1 passes through and is fixedly connected to the outer wall of discharge pipe 8. The outer wall of evaporator 1 near the bottom passes through and is fixedly connected to the outer wall of return pipe 7. The end of return pipe 7 away from evaporator 1 passes through and is fixedly connected to the inner wall of water inlet pipe 3. By mixing the light wastewater inside return pipe 7 with the light wastewater outside, the effect of heating the light wastewater outside is achieved. The inside of return pipe 7 is connected to the inside of water inlet pipe 3.

[0016] In this embodiment, during use, external light wastewater enters the heat exchange shell 2 through the water inlet pipe 3, and after heat exchange, it enters the evaporator 1 along the water inlet pipe 3 and is evaporated by the evaporator 1. After evaporation, the generated water vapor flows along the heat exchange tube 4. When the water vapor moves to the position where the heat exchange tube 4 contacts the water inlet pipe 3, its heat is absorbed by the water inlet pipe 3 and the light wastewater inside it. At the same time, the water vapor condenses into water droplets and flows out along the heat exchange tube 4. Meanwhile, during the evaporation process, the impurities in the light wastewater inside the evaporator 1 are located at the lower position due to gravity. This results in the water flowing out along the discharge pipe 8 being heavy wastewater, while the water at the upper position flows into the return pipe 7 and then merges into the inlet pipe 3, eventually returning to the evaporator 1 for secondary evaporation. This ensures that the water is lighter after evaporation, at which point only the heavy wastewater needs to be treated. The amount of heavy wastewater is equal to the amount of light wastewater minus the amount of water that has been evaporated, thus solving the problem of how to reduce the amount of wastewater discharged and treated.

[0017] As a preferred embodiment, a water pump 5 is included, the outlet end of which is fixedly connected to the inlet end of the inlet pipe 3. The water pump 5 is used to draw external light sewage into the equipment.

[0018] As a preferred embodiment, a second water pump 6 is provided, which is disposed between the two ends of the inlet pipe 3. The second water pump 6 is used to draw sewage from the return pipe 7 into the inlet pipe 3.

[0019] As a preferred embodiment, an air pump 9 is included, which is used to draw out the water vapor evaporated by the evaporator 1. The air pump 9 is disposed between the two ends of the heat exchange tube 4.

[0020] As a preferred embodiment, an electrical control box 10 is included, which provides the power required by the equipment. The electrical control box 10 is connected to water pump 5, water pump 6, air pump 9, and evaporator 1.

[0021] As a preferred approach, the heat exchange tube 4 is located in the internal region of the heat exchange shell 2 in a spiral and meandering shape. The shape of the heat exchange tube 4 ensures that the hot water condensed from the steam can flow slowly inside the heat exchange tube 4, and the flow path is extended to ensure that the heat it contains can be fully absorbed.

[0022] As a preferred method, the height of the discharge pipe 8 is lower than the height of the return pipe 7. By setting the height, it is ensured that impurities in the sewage can flow out of the discharge pipe 8 more easily due to gravity, thus ensuring that the water flowing out of the discharge pipe 8 is heavy sewage.
