DETAILED DESCRIPTION

[0019] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] Reference Figure 1 As shown, the embodiment of the present application discloses a high-temperature closed cooling tower with a precooling device, including: a bracket 11, which is arranged on the outer wall of the closed cooling tower 1; a device body 2, which is made of a material that can transfer heat and is arranged on the bracket 11; a water flow channel, which is turned back and opened in the device body 2 and connected to the closed cooling tower 1 for high-temperature water to flow; a shell 3, the device body 2 is arranged in the shell 3, and the inner wall surface of the shell 3 and the outer wall surface of the device body 2 have a gap of a fixed distance; a blower, which is used to supply air between the shell 3 and the device body 2.

[0021] In the utility model, a device body 2 is provided. Before the high-temperature water to be treated enters the closed cooling tower 1, it needs to be first introduced into the water flow channel in the device body 2; at the same time, the blower (not shown in the figure) is started, and the blower conveys a flowing airflow between the shell 3 and the device body 2. The flowing airflow takes away a large amount of heat on the device body 2, and the high-temperature water flowing through the device body 2 is cooled by air.

[0022] By using the utility model, high-temperature water can be pre-cooled before being sent into the closed cooling tower 1, which can effectively reduce the temperature of the high-temperature water entering the closed cooling tower 1, reduce the processing load of the rear-end closed cooling tower 1 on the high-temperature water, ensure the cooling efficiency of the closed cooling tower 1, and ensure the normal operation of the closed cooling tower 1.

[0023] Specifically, the device body 2 includes: an inner core 21; a plurality of first through holes 211 arranged in parallel, which penetrate the inner core 21 at a fixed angle inclined to the central axis of the inner core 21; a plurality of second through holes 222 arranged in parallel, which penetrate the inner core 21 at a fixed angle inclined to the central axis of the inner core 21; wherein the first through holes 211 and the second through holes 222 are arranged alternately and connected in pairs to form a water flow channel; an outer tube 22, the outer wall surface of the outer tube 22 and the inner wall surface of the inner core 21 are in interference contact; end covers 23, which are arranged at both ends of the outer tube 22 and abut against the inner core 21; and a rubber ring 24, which is arranged between the outer tube 22 and the end covers 23.

[0024] It is worth mentioning that the first through hole 211 and the second through hole 222 can be processed by electrospark machining to form a returning water flow channel. The returning water flow channel can delay the storage time of high-temperature water in the device body 2, increase the heat exchange time between the high-temperature water and the device body 2, improve the heat exchange efficiency, and ensure the cooling pretreatment effect of the high-temperature water.

[0025] Reference Figure 2As shown, the device body 2 can be made of copper to ensure heat exchange efficiency; the end cover 23 can be installed on the outer cylinder 22 by screws and press the rubber ring 24 to prevent high-temperature water from leaking out.

[0026] Specifically, the device body 2 also includes: a water supply hole and a water outlet hole 26, which penetrate the end cover 23 along the axial direction of the inner core 21 and connect to the water flow channel; wherein the water supply hole is connected to the water pump through a pipe, and the water outlet hole 26 is connected to the closed cooling tower 1 through a pipe.

[0027] Reference Figure 3 , Figure 4 and Figure 5 As shown, the utility model also includes: a loading component 4, which is U-shaped, arranged on the inner wall surface of the shell 3, and extends a fixed length along the outer wall surface of the device body 2, for carrying the device body 2 to ensure the installation stability of the device body 2 in the shell 3.

[0028] Among them, several loading components 4 are staggeredly arranged on the upper and lower sides of the device body 2 along the axial direction of the device body 2, so as to form a return airflow channel. Through the return airflow channel, the storage time of the airflow delivered by the blower in the shell 3 can be delayed, and the contact time between the airflow and the device body 2 can be increased, thereby further improving the heat exchange efficiency and ensuring the cooling pretreatment effect of the high-temperature water.

[0029] It is worth mentioning that the shell 3 can also adopt the installation method of the above-mentioned device body 2, which will not be repeated here. The user can take the device out of the shell 3 along the axial direction.

[0030] The utility model also includes balls 5. On the carrying part 4, a plurality of balls 5 are rotatably installed along the outer contour of the device body 2. By arranging the balls 5 to support the device body 2, it is convenient for users to take and place the device body 2 from the shell 3 along the axial direction, which is convenient for the later maintenance of the device body 2.

[0031] The utility model also includes: a rubber curtain 6, which is installed on the loading part 4 and extends toward the device body 2, and is located on both sides of the ball 5, for blocking the gap between the ball 5 and the outer wall of the device body 2, reducing air leakage in the axial direction, and guiding the airflow to flow along the return airflow channel.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.
