Description

Technical Field

[0001] This utility model relates to the technical field of heat energy recovery from winery wastewater, specifically a device for the recovery and reuse of heat energy from winery wastewater. Background Technology

[0002] Wastewater such as yellow water produced during the brewing of baijiu is characterized by high temperature, usually 40~60℃. If this type of wastewater is directly discharged into the biochemical unit of the sewage treatment system, it will have an adverse effect on the microorganisms in the biochemical unit, reduce the activity of biochemical reactions and make it difficult to meet the standards for effluent discharge. It also results in the waste of heat energy. Therefore, the heat in the wastewater can be recovered and reused with the help of corresponding heat recovery devices.

[0003] As disclosed in CN209991825U, a wastewater heat exchanger includes a shell and a heat exchange coil located within the shell and rotatable about the axis of the shell. The shell has an intermediate inlet pipe connected to the inlet end of the heat exchange coil and an intermediate outlet pipe connected to the outlet end of the heat exchange coil. A wastewater inlet pipe is inclinedly positioned on the side wall of the shell, and a wastewater outlet is provided at the bottom end of the shell. The angle between the tangent at the intersection of the wastewater inlet pipe and the shell and the wastewater inlet pipe is 0-30 degrees, so that the wastewater entering the shell forms a vortex that drives the heat exchange coil to rotate. This design solves the problems of scale buildup and blockage of the heat exchanger when wastewater flows through it, leading to a decrease in heat exchange capacity and increased operation, management, and maintenance of the wastewater source heat pump.

[0004] However, in actual use, existing wastewater heat recovery and reuse devices suffer from the accumulation of impurities in the wastewater into the heat exchanger. Long-term use leads to a large amount of impurities accumulating in the heat exchanger or adhering to the heat exchange tubes, affecting heat exchange efficiency and making it inconvenient to filter impurities in the wastewater. Moreover, the contact area between the heat exchange tubes and the wastewater is limited, resulting in low heat exchange efficiency.

[0005] For example, the comparative patents listed above have this problem;

[0006] Therefore, we provide a device for recovering and reusing heat energy from winery wastewater to solve the problems mentioned above. Utility Model Content

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Please see Figures 1-7 The present invention provides the following technical solution.

[0043] Example 1: To address the problem in existing technologies where impurities from wastewater enter the heat exchanger, leading to a buildup of impurities in the heat exchanger or adhering to the heat exchange tubes and affecting heat exchange efficiency over long-term use, this example provides a wastewater heat energy recovery and reuse device for wineries. The device includes a heat exchange box 1, a filter box 2, a wastewater inlet pipe 3, a filter screen 4, a geared motor 5, and a cleaning brush 6. The filter box 2 is fixedly connected to the upper left end of the heat exchange box 1, and the wastewater inlet pipe 3 is installed at the lower left end of the filter box 2. The geared motor 5 is fixedly installed at the left end of the filter box 2, and the output end of the geared motor 5 is fixedly connected to the cleaning brush 6. The geared motor 5 drives the cleaning brush 6 to rotate within the filter box 2. The filter screen 4 is inserted and installed in the middle of the filter box 2, and a sealing gasket is fitted between the filter screen 4 and the bottom of the filter box 2. A cleaning brush 6 is fitted to the left side of the filter screen 4 for cleaning. Figure 1 , Figure 2 and Figure 4 As shown, the high-temperature wastewater generated during the liquor production process enters the filter box 2 through the wastewater inlet pipe 3. The filter screen 4 in the filter box 2 can filter the impurities in the wastewater to prevent them from entering the heat exchange box 1 and accumulating, and to avoid the impurities adhering to the heat dissipation pipes, which would affect the actual heat exchange efficiency. During the filtration process, the geared motor 5 drives the cleaning brush 6 to rotate slowly in the filter box 2, thereby scraping and cleaning the impurities adhering to the filter screen 4, preventing the impurities from clogging the filter screen 4, and thus ensuring the smooth flow of the entire filtration process.

[0044] Example 2: To address the problem of inconvenience in filtering impurities in wastewater in existing technologies, this example provides a wastewater heat energy recovery and reuse device for wineries. The device includes a fixing mechanism 7. Fixing mechanisms 7 are located on both the front and rear sides of the lower end of the filter screen 4. Each fixing mechanism 7 consists of a protrusion 8, a support plate 9, a support rod 10, a connecting plate 11, and a connecting cap 12. The fixing mechanism 7 drives the filter screen 4 to form a disassembly structure within the filter box 2. The protrusion 8 is fixedly connected to the lower end of the filter screen 4, and the lower end of the filter screen 4 is fitted with a support plate 9 for support and positioning. The protrusion 8 is inserted into the middle of the support plate 9, and support rods 10 are fixedly connected to both the left and right ends of the support plate 9. The support rods 10 are engaged with the middle of the connecting plate 11, which is fixedly connected to the lower end of the filter box 2. A connecting cap 12 for locking and positioning is threaded onto the outer surface of the support rod 10, and the connecting cap 12 is engaged with the side of the connecting plate 11. Figure 3 , Figure 5 and Figure 6 As shown, after use, the connecting cap 12, which is threaded onto the outer surface of the support rod 10, can be rotated to disengage the support rod 10, thereby loosening the limit between the support rod 10 and the connecting plate 11. Then, the support plate 9 can be pulled down to disengage from the protrusion 8, and the support plate 9 can also cause the support rod 10 to disengage from the connecting plate 11, thereby loosening the pressure limit on the filter screen 4. Then, the filter screen 4 can be pulled down to facilitate cleaning of the filter screen 4 and the filtered material.

[0045] Example 3: To address the problem of limited contact area between the heat exchange tube and wastewater, resulting in low heat exchange efficiency in existing technologies, this example provides the following technical solution: a wastewater heat energy recovery and reuse device for a winery, equipped with a heat exchange tube and a wastewater discharge pipe 17. The heat exchange tube consists of a heating tube 13, an inlet pipe 14, an outlet pipe 15, and heating fins 16. The wastewater discharge pipe 17 is fixedly connected to the upper right end of the heat exchange box 1. The heating tube 13 is fixed inside the heat exchange box 1, with an inlet pipe 14 at the upper end and an outlet pipe 15 at the lower end. Multiple sets of heating fins 16 are evenly spaced on the outer side of the heating tube 13. Figure 2 and Figure 7 As shown, the filtered high-temperature wastewater enters the heat exchange box 1, while cold water enters the heating tube 13 through the inlet pipe 14. The wastewater heats the cold water in the heating tube 13 before it is discharged out through the outlet pipe 15. In addition, the heating fins 16 increase the contact area between the wastewater and the heating tube 13, thereby improving the actual heat exchange efficiency. The wastewater after heat exchange is then discharged out through the wastewater discharge pipe 17.

[0046] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
