[0002] With continuous economic progress, environmental issues, especially water pollution, have become key problems facing people today. Membrane treatment technology is favored in the field of wastewater treatment due to its stable operation and strong adaptability.
[0003] In the production and manufacturing process of wastewater treatment membranes, a large amount of hot water is often required to treat the membranes. For example, heat stabilization treatment can improve the membrane's heat resistance and chemical resistance, while cleaning treatment can improve the membrane's flux and retention performance. This hot water is generally obtained through electric heating.
[0004] However, the method of obtaining hot water by electric heating is not only energy-intensive, but also wastes a lot of water resources because the hot water usually contains harmful substances after treatment and is not usually reused. Utility Model Content
[0005] Therefore, the purpose of this utility model is to provide a steam heating and recycling system, which aims to produce the required hot water through a steam heating membrane, while recovering and reusing the steam to improve the utilization rate of water resources.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] Furthermore, the condensate collection unit includes a first water tank and a second water tank. The first water tank is connected to the heat exchanger and the steam generator through a pipe to store and keep the condensate output by the heat exchanger warm.

[0017] Furthermore, a fourth delivery pump is connected in series with the pipeline between the fourth water tank and the steam generator.
[0018] The beneficial effects of this utility model include at least the following: steam is generated by a steam generator, and then the steam exchanges heat with the production water in the membrane preparation device through a heat exchanger, so that the production water is heated to the temperature required for production, while the steam is cooled and liquefied into condensate.

[0026] In the manufacturing process of wastewater treatment membranes, hot water for production is typically obtained through electric heating. However, electric heating is energy-intensive, and the used production water often contains harmful substances, thus preventing its reuse and resulting in significant water waste. Therefore, this application proposes a method that uses steam to heat the membrane to produce the required hot water while simultaneously recovering and reusing the steam, thereby improving water resource utilization.
[0027] Specifically, please refer to Figure 1 The present invention provides a steam heating and recycling system, which is applied in a membrane preparation device 100. The steam heating and recycling system includes a steam generator 200, a heat exchanger 300, and a condensate collection unit 400.
[0028] In this system, a steam generator 200 heats liquid water to produce steam at a preset temperature. For example, the steam generator 200 can heat water in a boiler by burning fossil fuels to obtain production steam. A heat exchanger 300 is connected to the steam generator 200, allowing the steam generated by the steam generator 200 to enter the heat exchanger 300. The heat exchanger 300 then comes into contact with the production water in the membrane fabrication apparatus 100, resulting in heat exchange. The steam transfers heat to the production water in the membrane fabrication apparatus 100, heating the water to the required production temperature, while the steam cools and liquefies into condensate. A condensate collection unit 400 is connected to both the heat exchanger 300 and the steam generator 200. The condensate in the heat exchanger 300 is transported to the condensate collection unit 400 for storage. Furthermore, to improve water resource utilization, a portion of the condensate stored in the condensate collection unit 400 is transported to the steam generator 200 as a raw material for steam.
[0029] In some alternative embodiments, such as Figure 1 As shown, the condensate collection unit 400 includes a first water tank 410 and a second water tank 420.
[0030] Specifically, the first water tank 410 is connected to the heat exchanger 300 via a pipe. The condensate in the heat exchanger 300 is transported to the first water tank 410 for storage. To fully utilize the heat contained in the condensate, the first water tank 410 can be insulated, for example, by installing an insulation layer. The first water tank 410 is also connected to the steam generator 200 via a pipe. The condensate in the first water tank 410 is transported to the steam generator 200 for heating to generate steam. Because the condensate in the first water tank 410 is insulated, the energy required for heating in the steam generator 200 is correspondingly reduced. Furthermore, since some steam is reused, the water consumption of the steam generator 200 can also be reduced.
[0031] The second water tank 420 is connected to the first water tank 410 and the membrane preparation device 100 via a pipeline. The condensate in the first water tank 410 is transported to the second water tank 420 for temporary storage. When it is necessary to replenish the production water in the membrane preparation device 100, the second water tank 420 transports the stored water to the membrane preparation device 100 as raw material for production water. In this way, the steam can be reused, reducing the water consumption of the membrane preparation device 100.
[0032] In some alternative embodiments, such as Figure 1As shown, a first delivery pump 500 is connected in series with the pipeline between the first water tank 410 and the steam generator 200. The kinetic energy provided by the first delivery pump 500 orderly delivers the cooling water in the first water tank 410 to the steam generator 200, providing the steam generator 200 with the raw material for steam generation and enabling the reuse of steam. Optionally, the first delivery pump 500 can be a centrifugal pump or other power device.
[0033] In some alternative embodiments, such as Figure 1 As shown, a second transfer pump 600 is connected in series with the pipeline between the second water tank 420 and the first water tank 410. The cooling water in the first water tank 410 is orderly transported to the second water tank 420 by the kinetic energy provided by the second transfer pump 600. Optionally, the second transfer pump 600 can be a centrifugal pump or other power device.
[0034] In some optional embodiments, a third transfer pump (not shown in the figures) is connected in series with the pipeline between the second water tank 420 and the membrane preparation apparatus 100. The kinetic energy provided by the third transfer pump orderly transports the cooling water in the second water tank 420 to the membrane preparation apparatus 100, replenishing the membrane preparation apparatus 100 with production water and enabling the reuse of steam. Optionally, the third transfer pump can be a centrifugal pump or other power device.
[0035] In some alternative embodiments, such as Figure 1 As shown, the steam heating recycling system also includes a third water tank 700, which is connected to the membrane preparation device 100 via a pipeline. In this way, the production water used by the membrane preparation device 100 can be transported to the third water tank 700 for storage so that it can be treated later and prevented from being directly discharged and polluting the environment.
[0036] In some alternative embodiments, such as Figure 1 As shown, the steam heating and recycling system also includes a wastewater treatment device 800, which is connected to a third water tank 700 via a pipeline. In this way, the production water containing harmful substances in the third water tank 700 is transported to the wastewater treatment device 800, which purifies the water to obtain relatively clean water.
[0037] In some alternative embodiments, such as Figure 1 As shown, the steam heating recycling system also includes a fourth water tank 900, which is connected to the sewage treatment device 800 via a pipeline. In this way, the relatively clean water obtained after treatment by the sewage treatment device 800 is transported to the fourth water tank 900 for storage so that it can be reused later.
[0038] In some alternative embodiments, such as Figure 1As shown, the fourth water tank 900 is also connected to the steam generator 200 through a pipe, so that the relatively clean water stored in the fourth water tank 900 is transported to the steam generator 200, thereby providing the steam generator 200 with raw materials for generating steam and realizing the reuse of steam.
[0039] In some optional embodiments, a fourth transfer pump (not shown in the figures) is connected in series with the pipeline between the fourth water tank 900 and the steam generator 200. The kinetic energy provided by the fourth transfer pump orderly transports water from the fourth water tank 900 to the steam generator 200. Optionally, the fourth water tank 900 can be connected in parallel with the pipeline between the first water tank 410 and the steam generator 200, thus sharing the first transfer pump 500 and reducing equipment costs. Furthermore, the fourth transfer pump can optionally be a centrifugal pump or other power unit.
