Description

Technical Field

[0001] This utility model relates to the field of hydrolysis alkaline washing technology, specifically to a hydrolysis alkaline washing device with energy recovery function. Background Technology

[0002] Under the dual pressures of global energy structure transformation and increasingly stringent environmental protection requirements, energy conservation and emission reduction have become core issues for sustainable industrial development. As a crucial unit operation in many industrial sectors such as chemical, pharmaceutical, and dyeing industries for material purification and product refining, the operating efficiency, energy consumption, and environmental performance of hydrolysis-alkali washing systems directly impact a company's economic benefits and social responsibility.

[0003] The traditional hydrolysis alkaline washing process, which has been used for a long time, generally has the problem of wasting energy. Since the alkaline washing reaction usually needs to be heated to nearly 100°C, the waste alkaline liquid still carries a lot of residual heat after the reaction. If it is discharged directly, the residual heat of the waste alkaline liquid is not utilized, resulting in the waste of thermal energy. Utility Model Content

The waste alkali tank 1 and the alkaline washing tank 3 are connected by a connecting pipe 4. The bottom of the waste alkali tank 1 has a waste discharge port 5, and both the waste discharge port 5 and the connecting pipe 4 are equipped with control valves. The waste alkali solution discharged from the alkaline washing tank 3 enters the waste alkali tank 1 through the connecting pipe 4 for subsequent utilization.

[0026] In order to recover and reuse the residual heat in the waste alkali solution, combined with the attached Figure 2 and attached Figure 3 A waste heat recovery component is installed inside the waste alkali tank 1 to recover the waste heat carried in the waste alkali solution. The waste heat recovery component includes heat recovery pipes 6; multiple sets of heat recovery pipes 6 are installed inside the waste alkali tank 1. One end of each heat recovery pipe 6 extending to the outside is equipped with an input connector 7, and the other end is equipped with an output connector 8. Through the heat recovery pipes 6, the input connector 7, and the output connector 8, the waste heat in the waste alkali solution after the reaction can be recovered and utilized for preheating new alkali solution or for use in other process stages, promoting resource recycling and energy efficiency improvement.

[0027] In order to filter the waste alkaline solution, combined with the attached Figure 3 and attached Figure 4The waste alkali tank 1 and the alkali washing tank 3 are connected by a connecting pipe 4. The filter screen 9 is located at the top of the waste alkali tank 1 and is used in conjunction with the connecting pipe 4. A striking component is provided on the side of the filter screen 9 to accelerate the entry of waste alkali liquid into the waste alkali tank 1. The striking component includes a striking block 10 and a guide component. The striking block 10 is inserted into one side of the waste alkali tank 1.

Pull the striking block 10 back and forth repeatedly to manually strike the filter screen 9, preventing impurities from entering the mesh of the filter screen and accelerating the filtration of waste alkali liquid.

[0028] In specific implementation of this utility model:

[0029] First, the waste alkali liquid discharged from the alkali washing tank 3 passes through the connecting pipe 4 and then through the filter screen 9, which can preferentially filter the impurities in the waste alkali liquid. The filtered waste alkali liquid then enters the waste alkali tank 1.

[0030] Then, connect the input connector 7 and the output connector 8 to the external delivery pipe. The residual heat in the waste alkali solution after the reaction can be recovered and utilized through the heat recovery pipe 6. This heat can be used to preheat new alkali solution or for use in other process steps, promoting resource recycling and improving energy efficiency. Open the control valve, and the waste liquid after the residual heat has been recovered will be discharged directly through the waste outlet 5.

[0031] During use, pulling the pull ring outwards moves the striking block 10, and the L-shaped rod 12 slides in the groove 11. The striking block 10 is pulled back and forth repeatedly to manually strike the filter screen 9, preventing impurities from entering the mesh of the filter screen and accelerating the filtration of waste alkali liquid.
