Description

Technical Field

[0001] This application relates to the field of cooling tower technology, specifically a cooling tower with heat recovery function. Background Technology

[0002] A cooling tower is a heat exchange device used to cool circulating water in various industrial or air conditioning systems. Its main function is to dissipate the heat in hot water to the atmosphere through heat and mass exchange between water and air, thereby reducing the water temperature and allowing the circulating water to be used again for cooling purposes.

[0003] The cooling tower equipment we currently use consists of a tower body with nozzles inside. External hot water can be introduced into the tower body and sprayed out through the nozzles, allowing the hot water to come into contact with the air and achieve a cooling effect. However, while cooling the hot water, a large amount of hot steam is discharged from the tower body. This hot steam contains moisture, and it is usually difficult to recover and collect, resulting in energy waste.

[0004] Therefore, it is necessary to provide a cooling tower with heat recovery function to solve the above problems. Utility Model Content

[0005] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a cooling tower with heat recovery function, which achieves the effect of recovering the hot steam discharged from the cooling tower.

[0006] The technical solution adopted by this application to solve its technical problem is as follows: It includes a cooling tower assembly, characterized in that: the cooling tower assembly includes a tower body, on which a hot water pipe is fixedly installed. The hot water pipe can introduce external hot water that needs to be cooled. The hot water pipe extends to the middle of the inner side of the tower body. Several sets of nozzles a are fixedly installed on the hot water pipe inside the tower body. A sealing cover is fixedly installed on the tower body. The sealing cover is used to centrally guide the hot steam discharged by the fan a. A fixing plate is fixedly installed on the sealing cover. A drain pipe is fixedly installed on the fixing plate. The fixing plate is used to fix and support the drain pipe. The bottom of the drain pipe extends to the bottom of the tower body. An upper water pipe is fixedly installed on the tower body. A water pump is fixedly installed on the upper water pipe. The end of the upper water pipe extends to the top of the inner side of the tower body. Several sets of nozzles b are fixedly installed on the upper water pipe. The end of the upper water pipe is located above the nozzles a.

[0007] Furthermore, a sleeve is fixedly installed on the drain pipe, and an inlet pipe and an outlet pipe are fixedly installed on the inner side of the sleeve. A copper pipe is fixedly installed between the inlet pipe and the outlet pipe, and a heat-conducting plate is fixedly installed on the drain pipe.

[0008] Furthermore, a fixing plate is fixedly installed on the outer side of the copper tube, and the fixing plate is fixedly installed on the inner wall of the sleeve.

[0009] Furthermore, a ventilation opening is fixedly installed on the tower body, which is used to introduce external air.

[0010] Furthermore, packing material is fixedly installed inside the tower body, and several sets of gaps are opened inside the packing material.

[0011] Furthermore, a ladder is fixedly installed on the tower body, and the ladder is located on the outside of the tower body.

[0012] The beneficial effects of this application are:

[0013] This application provides a cooling tower with heat recovery function. Through the cooperation between nozzle a and packing, hot water can be cooled and the generated high-temperature steam can be dispersed upward, thereby cooling the hot water. At the same time, through the cooperation between fan a and fan b, the hot steam discharged upward inside the tower can be guided into the drain pipe and the inside of the sleeve, so that some of the hot steam can be collected and finally form condensate that re-enters the inside of the tower, thereby enabling the condensate to be recycled.

[0014] This application provides a cooling tower with heat recovery function. The tower body can store a certain amount of water, and a water pump allows the water to enter the water inlet pipe. Then, the water is discharged above the nozzle a through nozzle b. This allows the cold water sprayed by nozzle b to come into contact with the hot water in nozzle a while the hot water is being discharged from nozzle a, thereby accelerating the cooling of the hot water and improving the efficiency of the equipment.

Detailed Implementation

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0025] like Figures 1-5 As shown, this application provides a cooling tower with heat recovery function, including a cooling tower assembly 10. The cooling tower assembly 10 is used to cool external hot water after it is introduced, allowing the hot water to be reused later. The cooling tower assembly 10 includes a tower body 11, on which a hot water pipe 12 is fixedly installed. The hot water pipe 12 can introduce external hot water that needs to be cooled, and extends to the inner middle of the tower body 11. Several sets of nozzles a14 are fixedly installed on the hot water pipe 12 located inside the tower body 11. When hot water is introduced through the hot water pipe 12, the hot water is sprayed inside the tower body 11 through the nozzles a14, and the sprayed water falls inside the tower body 11, allowing the hot water to be in contact with the air for a long time, thereby cooling the hot water.

[0026] Meanwhile, a vent 15 is fixedly installed on the tower body 11. The vent 15 is used to introduce external air. A fan a110 is fixedly installed on the tower body 11. When the fan a110 is turned on, the fan a110 can exhaust the hot steam formed after the heat dissipation inside the tower body 11. At the same time, the fan a110 can quickly introduce the vent 15 into the interior of the tower body 11, so that the external air can come into contact with the falling hot water, thereby improving the heat dissipation effect of the hot water. After cooling, the water will be collected at the bottom of the inner side of the tower body 11.

[0027] Meanwhile, a packing material 16 is fixedly installed inside the tower body 11. The packing material 16 has several sets of gaps inside. When the nozzle a14 sprays hot water, the hot water will pass through the gaps of the packing material 16. The packing material 16 can increase the contact area and contact time between water and air, thereby improving the heat exchange efficiency.

[0028] A sealing cover 18 is fixedly installed on the tower body 11. The sealing cover 18 is used to centrally guide the hot steam discharged by the fan a110. At the same time, a fixing plate 19 is fixedly installed on the sealing cover 18, and a drain pipe 17 is fixedly installed on the fixing plate 19. The fixing plate 19 is used to fix and support the drain pipe 17. The fan b111 is fixedly installed inside the drain pipe 17, and the bottom of the drain pipe 17 extends to the bottom of the tower body 11. When the fans a110 and b111 are turned on, some hot steam will be introduced into the interior of the drain pipe 17. The hot steam is collected through the drain pipe 17, and the hot steam will continuously form liquid inside the drain pipe 17. Eventually, it will re-enter the interior of the tower body 11, thus achieving the work of recovering and reusing the hot steam.

[0029] A heat-conducting plate 112 is fixedly installed on the drain pipe 17, so that when superheated steam is introduced, the drain pipe 17 will dissipate heat through the heat-conducting plate 112, thereby improving the efficiency of the hot steam in forming liquid.

[0030] Furthermore, a sleeve 113 is fixedly installed on the drain pipe 17. An inlet pipe 114 and an outlet pipe 115 are fixedly installed on the inner side of the sleeve 113. A copper pipe 116 is fixedly installed between the inlet pipe 114 and the outlet pipe 115. The inlet pipe 114 can introduce external cold water. When the drain pipe 17 collects hot steam, the hot steam will pass through the inside of the sleeve 113 and enter the inside of the copper pipe 116. At the same time, the inside of the copper pipe 116 contains cold water. The hot steam is gaseous water. When it encounters cold air or objects, the temperature of the steam will drop rapidly. Thus, when the hot steam comes into contact with the copper pipe 116, it can further improve the efficiency of liquid forming and cool down the superheated steam. The water inside the copper pipe 116 can be circulated through the outlet pipe 115.

[0031] A fixing plate 117 is fixedly installed on the outside of the copper tube 116, and the fixing plate 117 is fixedly installed on the inner wall of the sleeve 113, so that the copper tube 116 can be fixedly installed inside the sleeve 113 through the fixing plate 117.

[0032] A water inlet pipe 118 is fixedly installed on the tower body 11, and a water pump 121 is fixedly installed on the water inlet pipe 118. The end of the water inlet pipe 118 extends to the inner top of the tower body 11, and several sets of nozzles b120 are fixedly installed on the water inlet pipe 118. The end of the water inlet pipe 118 is located above the nozzles a14, so that the water collected inside the tower body 11 can be introduced into the water inlet pipe 118 through the water pump 121, and then the nozzles b120 can discharge this water inside the tower body 11. In this way, when the nozzles a14 discharge hot water, the cold water sprayed by the nozzles b120 can come into contact with the hot water of the nozzles a14, thereby accelerating the cooling of the hot water and further improving the use effect of the equipment. It can also be recycled.

[0033] A ladder 13 is fixedly installed on the tower body 11. The ladder 13 is located on the outside of the tower body 11, so that the cooling tower assembly 10 can be easily and safely accessed by workers to the top of the cooling tower assembly 10 and other parts that need maintenance.

[0034] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
