Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a high-efficiency and energy-saving wastewater distillation device. Background Technology

[0002] In the fields of industrial production and environmental protection, wastewater distillation treatment technology is widely used. Currently, common distillation processes mainly involve heating materials in equipment such as reaction vessels or heating tanks to raise the material temperature above its boiling point, and then cooling it through a condenser to collect the product. Some processes are used to remove solvents by heating the solvent to its boiling point and then collecting it through a condenser. In addition, although multi-effect evaporation technology can utilize the residual temperature during the heating process for reheating, this technology has a complex equipment structure and is difficult to operate and maintain.

[0003] Existing distillation processes have many obvious drawbacks. On the one hand, the heating process consumes a huge amount of energy, with a large amount of energy being used to heat materials or solvents to their boiling points, resulting in serious energy waste. This not only increases production costs but also does not conform to the environmental protection concept of energy conservation and emission reduction. On the other hand, the condenser requires a large amount of cooling water to achieve the cooling effect during operation. This not only increases water consumption but may also cause secondary pollution to the environment due to the discharge of cooling water. At the same time, the use of a large amount of cooling water also increases the operating costs of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency and energy-saving wastewater distillation device to solve the problems mentioned in the background art, such as high energy consumption for heating, large amount of cooling water required for condensers, resulting in energy waste, increased production costs, and potential environmental pollution.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency and energy-saving wastewater distillation device, comprising a distillation tank, a first condenser and a second condenser are provided on one side of the distillation tank, a first steam inlet is fixedly installed on the upper outer surface of one side of the distillation tank, and a first steam outlet is fixedly installed on the lower outer surface of the other side of the distillation tank, a first material inlet is fixedly installed on the upper outer surface of the distillation tank above the first steam outlet, and a first material outlet is fixedly installed on the outer surface of the distillation tank above the first material inlet, a solenoid valve is fixedly installed at the end of the first material inlet facing the first condenser, a flow guiding cavity is opened inside the side surface of the first condenser and the second condenser, and a heat exchange tube is fixedly installed inside the first condenser and the second condenser.

A steam reflux port is fixedly installed on the outer surface of the first condenser and the second condenser below the second material outlet, and a steam exhaust port is fixedly installed on the outer surface of the first condenser and the second condenser above the second material inlet.

[0007] By adopting the above technical solution, the connection between the first condenser and the second condenser in terms of material inlet and outlet and steam inlet and outlet is more reasonable, which helps to realize the orderly flow of materials and steam in the equipment and creates conditions for multi-stage utilization of heat and efficient condensation of materials.

[0008] Preferably, one end of the first material outlet is fixedly connected to the discharge pipe, and the other end of the discharge pipe penetrates the inner top surface of the first condenser. The lower end of the first condenser penetrates the inner top surface of the second condenser through a tubular outlet, and the lower end of the second condenser is provided with a tubular outlet.

[0009] By adopting the above technical solution, the material discharged from the distillation tank is made to flow in an orderly manner between the first condenser and the second condenser, which further optimizes the condensation process of the material and improves the overall processing efficiency of the equipment.

[0010] Preferably, one end of the solenoid valve is fixedly connected to one end of the feed pipe, and the other end of the feed pipe is fixedly connected to the second material outlet at the upper end of the first condenser. The ends of the second material outlet and the second material inlet facing the inside of the first condenser penetrate the inner surface of the first condenser and the second condenser. The ends of the second material outlet and the second material inlet located inside the first condenser and the second condenser are respectively fixedly connected to the two ends of the heat exchange tube, and the heat exchange tube is designed in a spiral shape.

[0011] By adopting the above technical solution, a circulation path is formed in which the material enters the distillation tank from the second condenser through the first condenser. The spiral heat exchange tube can increase the contact area and time between the material and the steam, improve the heat exchange effect, and reduce the dependence on cooling water.

[0012] Preferably, one end of the first steam outlet is fixedly connected to a guide pipe, and the other end of the guide pipe is fixedly connected to the steam return port at the upper end of the first condenser.

[0013] By adopting the above technical solution, a channel is provided for the steam after the distillation tank is used to enter the first condenser, so that the waste heat of the steam can be used to heat the material in the first condenser, thereby achieving the purpose of heat recovery and utilization and reducing energy consumption.

[0014] Preferably, a steam transfer pipe is fixedly connected between the steam outlet of the first condenser and the steam return port of the second condenser, and a material transfer pipe is fixedly connected between the second material inlet of the first condenser and the second material outlet of the second condenser.

At the same time, the steam outlet on the first condenser is connected to the steam return port on the second condenser through the steam transfer pipe, so that the steam can be recycled between the two condensers. This realizes multi-stage utilization of heat. Compared with the traditional distillation process, it greatly reduces the energy consumption during the heating process, which is in line with the environmental protection concept of energy conservation and emission reduction, and effectively reduces production costs.

[0029] Please see Figures 1-6 This utility model provides a technical solution: a high-efficiency and energy-saving wastewater distillation device.

[0030] Example 1: This example discloses a distillation tank 1, with a first condenser tank 2 and a second condenser tank 3 on one side.

A flow guiding cavity 18 is opened inside the side surface of the first condenser tank 2 and the second condenser tank 3, and a heat exchange tube 19 is fixedly installed inside the first condenser tank 2 and the second condenser tank 3.

[0031] Steam enters the distillation tank 1 through the first steam inlet 4, while the material is injected into the distillation tank 1 through the first material inlet 6 after the solenoid valve 8 is opened. The material is heated by steam after entering the distillation tank 1, and the distilled material is discharged through the first material outlet 7. The heat-exchanged steam is discharged outward through the first steam outlet 5. The discharged material enters the first condenser 2 and the second condenser 3. The waste heat of the steam and the flow of the material are used to achieve preheating and condensation of the distilled material, respectively.

[0032] The distillation tank 1 can be replaced with a distillation kettle according to the actual working conditions. The first condenser tank 2 and the second condenser tank 3 can be replaced with condensers according to the actual working conditions. At the same time, if the condensation effect or preheating effect of the material after passing through the first condenser tank 2 and the second condenser tank 3 is insufficient, a multi-stage processing structure can be formed by increasing the number of the first condenser tank 2 and the second condenser tank 3 to ensure that the condensation and preheating effect meets the requirements of the production process.

[0033] Example 2: This example discloses the following based on Example 1: A second material inlet 9 is fixedly installed on the lower outer surface of the side of the first condenser 2 and the second condenser 3 facing away from the distillation tank 1, and a second material outlet 10 is fixedly installed on the upper outer surface of the side of the first condenser 2 and the second condenser 3 facing the distillation tank 1. A steam reflux port 11 is fixedly installed on the outer surface of the first condenser 2 and the second condenser 3 below the second material outlet 10, and a steam exhaust port 12 is fixedly installed on the outer surface of the first condenser 2 and the second condenser 3 above the second material inlet 9.

[0034] The first material outlet 7 is fixedly connected to one end of the discharge pipe 13, and the other end of the discharge pipe 13 penetrates the inner top surface of the first condenser 2. The lower end of the first condenser 2 penetrates the inner top surface of the second condenser 3 through a tubular outlet. The lower end of the second condenser 3 is provided with a tubular outlet.

The ends of the second material outlet 10 and the second material inlet 9 facing the inside of the first condenser 2 and the second condenser 3 penetrate the inner surface of the first condenser 2 and the second condenser 3. The ends of the second material outlet 10 and the second material inlet 9 located inside the first condenser 2 and the second condenser 3 are respectively fixedly connected to the two ends of the heat exchange tube 19, and the heat exchange tube 19 is designed in a spiral shape.

[0036] The first steam outlet 5 is fixedly connected to one end of the guide pipe 15, and the other end of the guide pipe 15 is fixedly connected to the steam return port 11 at the upper end of the first condenser 2.

[0037] A steam transfer pipe 16 is fixedly connected between the steam outlet 12 on the first condenser 2 and the steam return port 11 on the second condenser 3, and a material transfer pipe 17 is fixedly connected between the second material inlet 9 on the first condenser 2 and the second material outlet 10 on the second condenser 3.

[0038] The ends of the steam return port 11 and the steam discharge port 12 facing the interior of the first condenser 2 and the second condenser 3 both penetrate the inner surface of the guide cavity 18.

[0039] During the distillation process, the material to be distilled first enters the heat exchange tube 19 in the second condenser 3 through the second material inlet 9. The heat exchange tube 19 is injected into the heat exchange tube 19 in the first condenser 2 through the second material outlet 10, the material transfer pipe 17 and the second material inlet 9 on the first condenser 2. The heat exchange tube 19 in the first condenser 2 injects the material into the distillation tank 1 through the second material outlet 10 and the feed pipe 14, and through the first material inlet 6 and the solenoid valve 8 for distillation. The gaseous material after distillation is injected downward into the first condenser 2 and the second condenser 3 through the first material outlet 7 and the discharge pipe 13.

[0040] The steam distilled in the distillation tank 1 is injected into the guide cavity 18 inside the side surface of the first condenser tank 2 through the first steam outlet 5, the guide pipe 15 and the steam return port 11. The steam in the guide cavity 18 of the first condenser tank 2 is discharged to the guide cavity 18 inside the side surface of the second condenser tank 3 through the steam outlet 12 and the steam transfer pipe 16.

[0041] When the material to be distilled spirals upward in the heat exchange tube 19, it exchanges heat with the gaseous material evaporated inside the first condenser 2 and the second condenser 3, so that the gaseous material can be condensed and the use of cooling water is eliminated. The condensed material can be discharged downward through the tubular opening at the lower end of the second condenser 3, while the steam in the guide cavity 18 can be collected and reused to preheat the subsequent material.
