Description

Technical Field

[0001] This utility model relates to the field of heat exchange technology, specifically to a heat exchange device for pharmaceutical wastewater. Background Technology

[0002] Pharmaceutical wastewater is a general term for all types of wastewater generated during the pharmaceutical production process. Because pharmaceutical processes involve a large number of raw materials, intermediates, solvents, and byproducts, pharmaceutical wastewater is characterized by complex composition, high pollutant concentrations, large fluctuations in water quality and quantity, and high treatment difficulty. The wastewater may contain dozens or even hundreds of organic pollutants, including salts, antibiotics, hormones, alkaloids, nitro compounds, benzene compounds, and organic solvents (such as DMF, DMSO, methanol, ethanol, acetone, and diethyl ether).

[0003] In the heat exchange process of pharmaceutical wastewater, various solid substances in the wastewater easily adhere to the outer wall of the heat exchange pipes, affecting the heat exchange efficiency. Therefore, regular cleaning of the heat exchange pipes is necessary. However, since the heat exchange tubes of current heat exchangers are generally fixed inside the heat exchange equipment, cleaning requires personnel to enter the equipment. The space inside the equipment is often very narrow, causing many inconveniences for the cleaning work. Utility Model Content

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] To address the technical problem of difficult cleaning of heat exchange tubes, this utility model provides a pharmaceutical wastewater heat exchange device that allows for easy and quick removal and cleaning of the heat exchanger.

[0019] It should be noted that the pharmaceutical wastewater heat exchange equipment described in this utility model is used for, but not limited to, heat exchange of pharmaceutical wastewater. It can also be applied to heat exchange of other types of wastewater. The principle of applying the pharmaceutical wastewater heat exchange equipment to other types of wastewater is essentially the same as that applied to pharmaceutical wastewater, and will not be elaborated here.

[0020] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of the pharmaceutical wastewater heat exchange equipment provided in this embodiment of the utility model. The pharmaceutical wastewater heat exchange equipment includes a heat exchange tank 1 and a heat exchanger 2.

[0021] The heat exchange tank 1 is an open structure, allowing wastewater to be introduced into it through the top opening. An outlet 11 is located at the bottom of the heat exchange tank for discharging the wastewater after heat exchange.

[0022] The heat exchanger 2 includes an inlet pipe 21, an outlet pipe 22, and a heat exchange plate 23. The heat exchange plate 23 is detachably connected to the inlet pipe 21 and the outlet pipe 22. The heat exchange plate 23 is arranged inside the heat exchange pool 1 and is also detachably connected to the heat exchange pool 1. The inlet pipe 21 and the outlet pipe 22 can be fixed to a suitable position above the heat exchange pool 1 by fixing devices such as fixing brackets.

[0023] Driven by external equipment such as a pump, the heat exchange medium flows from the inlet pipe 21 into the heat exchange plate 23. After heat exchange, it flows from the heat exchange plate 23 to the outlet pipe 22. The outlet pipe 22 guides the heat exchange medium to other equipment. For example, when the heat exchange medium absorbs heat, the outlet pipe 22 guides the heat exchange medium to a radiator or heat-using equipment. When the heat exchange medium releases heat, the outlet pipe 22 guides the heat exchange medium to a heating device.

[0024] When cleaning of the heat exchange plate 23 is required, the heat exchange plate 23 is separated from the inlet pipe 21 and the outlet pipe 22. The heat exchange plate 23 is then removed from the heat exchange tank 1 using lifting equipment for cleaning. This provides a spacious cleaning area, making cleaning easier.

[0025] Please see Figure 2 , Figure 2 yes Figure 1 Top view of the heat exchange plate.

[0026] In some embodiments, a heat exchange pipe 231 is formed inside the heat exchange plate 23, and multiple interfaces 231A are formed on the surface of the heat exchange plate 23. The liquid inlet pipe 21 and the liquid outlet pipe 22 are respectively connected to different interfaces 231A. The heat exchange medium flows along the heat exchange pipe 231 inside the heat exchange plate 23.

[0027] Based on the above embodiment, the heat exchange pipe 231 includes two main pipes 231B and multiple branch pipes 231C. The branch pipes 231C are arranged side by side at intervals, and both ends of the branch pipes 231C are respectively connected to the two main pipes 231B. The interface 231A is located on the main pipe 231B. The inlet pipe 21 and the outlet pipe 22 are respectively connected to different main pipes 231B. The heat exchange medium flows into the main pipe 231B from the inlet pipe 21, then splits into different branch pipes 231C, and then converges into another main pipe 231B, and flows out from the outlet pipe 22.

[0028] Based on the above embodiment, the heat exchange plate 23 also forms a flow hole 231D between the branch pipes 231C. The flow hole 231D connects the upper surface and the lower surface of the heat exchange plate 23, allowing sewage to flow through the heat exchange plate 23.

[0029] Based on the above embodiment, a float 3 is also provided between the branch pipes 231C. The float 3 is fixedly connected to the heat exchange plate 23, providing buoyancy to the heat exchange plate 23 to reduce the load at the connection between the heat exchange plate 23 and the heat exchange tank 1. The float 3 can be an air bag or a low-density material, such as foam blocks. Ideally, the float 3 should be evenly distributed on the heat exchange plate 23 to ensure uniform stress distribution and maintain a horizontal posture in the sewage. Furthermore, the amount of float 3 should be appropriate; under operating conditions, the overall weight of the heat exchange plate 23 and the float 3 should be slightly greater than the buoyancy it experiences. This minimizes the load at the connection between the heat exchange plate 23 and the heat exchange tank 1 while preventing the heat exchange plate 23 from floating on the water surface.

[0030] In some embodiments, the heat exchanger 2 includes a plurality of heat exchange plates 23 and connecting pipes 24. The heat exchange plates 23 are arranged side by side at intervals along the height direction, and the connecting pipes 24 connect the interfaces 231A of two adjacent heat exchange plates 23. The connecting pipes 24 are flexible pipes. The flexible connecting pipes 24 provide greater flexibility when cleaning the heat exchange plates 23.

[0031] Based on the above embodiment, the uppermost heat exchange plate 23 is detachably connected to the inlet pipe 21 and the outlet pipe 22 via a connecting pipe 24. The connecting pipe 24 can be quickly connected and disconnected from the inlet pipe 21, the outlet pipe 22, and the interface 231A via quick connectors.

[0032] In some embodiments, the heat exchanger 2 further includes a chain 25, and a connecting ring 26 is provided on the surface of the heat exchange plate 23. Adjacent heat exchange plates 23 are connected to the connecting ring 26 via the chain 25. Under the action of gravity, each heat exchange plate 23 is located at a different height in the heat exchange pool 1, and they exchange heat together. The flexible connection of the chain 25 provides flexibility to the heat exchange plate 23. Under the combined action of gravity, buoyancy, and the tension of the chain 25, the heat exchange plate 23 is suspended at a suitable depth in the heat exchange pool 1.

[0033] Based on the above embodiment, the uppermost heat exchange plate 23 is detachably connected to the heat exchange pool 1 via a chain 25.

[0034] Please see Figure 3 , Figure 3 yes Figure 1 Enlarged view of point A in the middle.

[0035] In some embodiments, the heat exchanger 2 further includes a connecting rod 27, and a placement seat 12 is provided on the upper surface of the heat exchange pool 1. The placement seat 12 forms a placement groove, and the uppermost heat exchange plate 23 is connected to the connecting rod 27 by a chain 25. The connecting rod 27 can be placed in the placement groove. During cleaning, after disconnecting the pipe, the connecting rod 27 can be lifted using a lifting device to remove the heat exchange plate 23 from the heat exchange pool 1.

[0036] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
