It is widely used in various heat exchange equipment, such as cooling tower, condenser, heat exchanger, etc. to maintain the normal working temperature of these devices. The circulating cooling water absorbs the heat generated by the equipment, so that the equipment is kept in the appropriate working temperature range, thereby ensuring the continuity and stability of the production process. However, with the absorption of heat, the temperature of the cooling water gradually rises, and if it is not cooled, it will affect the cooling effect and equipment performance.
[0003] However, the traditional circulating cooling water cooling method is mainly to send high-temperature cooling water to the cooling tower, and through natural or forced ventilation, the heat is dissipated to the atmosphere, so that the cooling water temperature is reduced and then recycled. This method is simple and effective, but a large amount of heat energy contained in the cooling water is directly discharged to the atmosphere during the heat dissipation process, which cannot be effectively utilized, resulting in energy waste. To solve the above problems, the present application provides a circulating cooling water heat energy recovery device. UTILITARIAN CONTENT

[0028] Example 1:
[0029] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a circulating cooling water heat recovery device includes:
[0030] The housing mechanism 1 and the heat exchange mechanism 2 assembled inside the housing mechanism 1;
[0031] The housing mechanism 1 includes a protective box 11, and a heat recovery box 15 is fixedly installed inside the protective box 11;
[0032] The heat exchange mechanism 2 includes a heat exchange box 21 that is slidably installed inside the heat recovery box 15. The top and bottom of the heat exchange box 21 are provided with water storage chambers 27, which are connected to each other through a conveying pipe 28. A heat exchange chamber 211 is provided at the center of the heat exchange box 21. Heat-conducting fins 29 are fixedly installed inside the heat exchange box 21, penetrating the water storage chamber 27 and the heat exchange chamber 211. A flow divider 22 is installed at the front end of the heat exchange box 21, and a water inlet pipe 25 is connected to the front end of the flow divider 22.
[0033] As can be seen from the above, by placing the device in a suitable position during use, high-temperature cooling water is introduced into the diversion shroud 22 through the water inlet pipe 25, allowing the high-temperature cooling water to flow into the heat exchange chamber 211. The heat exchange box 21 is made of a heat-conducting material, which facilitates the transfer of heat from the high-temperature cooling water in the heat exchange chamber 211 to the water storage chamber 27, thereby heating the water in the water storage chamber 27. Since the multiple heat exchange chambers 211 are interconnected, the high-temperature cooling water can flow in a flat manner.
[0034] The water storage chambers 27 distributed vertically allow for water circulation, facilitating the replacement of heating positions for the water within the chambers. This allows for the full absorption of heat energy from the high-temperature cooling water in the heat exchange chamber 211, effectively improving the heat exchange efficiency. Simultaneously, the heat-conducting fins 29 enable the high-temperature cooling water in the heat exchange chamber 211 to flow along the fins, absorbing heat from the cooling water and transferring it to the water storage chamber 27 for heating.
[0035] After use, the heat exchange box 21 can be pulled out of the heat recovery box 15, which makes it easy to separate the entire heat exchange mechanism 2 from the heat recovery box 15. At the same time, the diversion hood 22 can be disassembled and separated from the heat exchange box 21, which allows the staff to easily clean the scale accumulated inside the water storage chamber 27 and the heat exchange chamber 211, so that the heat exchange box 21 can maintain a good heat exchange effect and bring more convenience to maintenance.
[0036] Depend on Figure 3 It can be seen that a circulation pump 17 is fixedly installed on the top of the heat energy recovery box 15, a water supply pipe 18 is connected between the water outlet of the circulation pump 17 and the bottom of the heat energy recovery box 15, and a water suction pipe 19 is connected between the water suction end of the circulation pump 17 and the top of the heat energy recovery box 15.
[0037] As can be seen from the above, the circulating pump 17 can extract water from the upper water storage chamber 27 through the suction pipe 19, and the extracted water can be sent into the lower water storage chamber 27 through the delivery pipe 18. With the help of the delivery pipe 28, the water in the upper and lower water storage chambers 27 can be circulated, and the contact position with the heat exchange chamber 211 can be easily replaced, so as to uniformly heat the water in the water storage chamber 27.
[0038] For details, please refer to Figure 1 and Figure 3 As shown, the top of the heat recovery box 15 is connected to a water inlet pipe 14 that extends out of the protective box 11, and the bottom of the heat recovery box 15 is connected to a water outlet pipe 13 that extends out of the protective box 11.
[0039] As can be seen from the above, water can be easily injected into the heat recovery tank 15 through the water injection pipe 14, and the injected water can enter the water storage chamber 27. The heated water in the water storage chamber 27 can be easily discharged for use through the water outlet pipe 13.
[0040] For details, please refer to Figure 2 As shown, the rear end of the heat recovery box 15 is connected to a drain pipe 16 extending out of the protective box 11, and the front end of the protective box 11 is hinged to a protective door 12.
[0041] As can be seen from the above, after the high-temperature cooling water exchanges heat through the heat exchange chamber 211, the high-temperature cooling water can be cooled and discharged through the drain pipe 16, which can conveniently continue to provide cooling effect to the mechanical equipment. By opening the protective door 12, the heat exchange mechanism 2 can be easily pulled out from the heat recovery box 15 for cleaning and maintenance operations.
[0042] Example 2:
[0043] refer to Figure 4 and Figure 5 As shown, the surface of the heat-conducting fins 29 is provided with through holes 210 and flow ports 212. The through holes 210 are located inside the water storage cavity 27, and the flow ports 212 are located inside the heat exchange cavity 211.
[0044] As can be seen from the above, the heat exchange chambers 211 can be connected through the flow port 212, so that the high temperature cooling water can flow in each other in multiple heat exchange chambers 211 when it flows, and the high temperature cooling water can flow in a flat manner. The water in the water storage chamber 27 can be circulated laterally by using the through hole 210.
[0045] refer to Figure 4 and Figure 5 As shown, the flow divider 22 is fixed to the heat recovery box 15 by the second fixing knob 26, and the flow divider 22 is fixed to the heat exchange box 21 by the first fixing knob 24.
[0046] As can be seen from the above, the second fixing knob 26 can be used to easily fix and seal the flow distribution cover 22 and the heat recovery box 15 to prevent them from falling off. It can also be used to easily disassemble and separate the flow distribution cover 22 and the heat recovery box 15. By inserting the front end of the heat exchange box 21 into the flow distribution cover 22, it can be easily assembled. The first fixing knob 24 can be used to easily fix the heat exchange box 21 and the flow distribution cover 22. It can also be used to easily disassemble and clean the heat exchange box 21 and the flow distribution cover 22.
[0047] refer to Figure 4 and Figure 5 As shown, a handle 23 is fixedly installed at the front end of the diversion shroud 22, and the handle 23 is distributed on both sides of the water inlet pipe 25.
[0048] As can be seen from the above, by using the handle 23, the diversion shroud 22 can be easily pulled forward, the heat exchange box 21 can be easily pulled out from the heat recovery box 15, and the entire heat exchange mechanism 2 can be easily pulled out, making it convenient for staff to perform maintenance and installation operations.
