Description

Technical Field

[0001] The invention relates to the technical field of cooling towers, in particular to an improved spray pipeline and a cooling tower containing the same. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to lower the water temperature. It uses the principles of evaporative heat dissipation, convection heat transfer, and radiation heat transfer to dissipate excess heat generated in industry or refrigeration and air conditioning to lower the water temperature through evaporative heat dissipation to ensure the normal operation of the system.

[0003] The spray pipe is an important part of the cooling tower. After the water enters the spray pipe, some of the impurities it carries will be deposited in the pipe, and some will be attached to the nozzle, thereby causing the flow of water to be obstructed and the nozzle to be blocked. As a result, the spray pipe needs to be cleaned or repaired regularly during use, reducing the use value of the cooling tower. Summary of the Invention

[0004] The present invention discloses an improved spray pipe and a cooling tower containing the same, aiming to solve the technical problem that the spray pipe is an important part of the cooling tower. After the water enters the spray pipe, some of the impurities it carries will be deposited in the pipe, and some will adhere to the nozzle, thereby causing the flow of the water to be obstructed and the nozzle to be blocked, thereby causing the spray pipe to need to be regularly cleaned or maintained during use.

[0006] By providing a water treatment mechanism, when the water entering the main pipe 1 and the main pipe 2 passes through the treatment box, the filter plate filters it. After the filter plate has been used for a period of time, the hydraulic cylinder 2 is adjusted to drive the sealing semicircles at the upper and lower ends to seal the water guide holes and the water inlet holes, and then the drive motor 1 is started to drive the filter plate to rotate in the treatment box. During the rotation, the water retained in the treatment box flushes the filter plate, thereby removing the impurities attached to it.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] The improved spray pipe and cooling tower containing the same disclosed in the present invention are mainly used in cooling towers where the spray pipe is an important part. After the water enters the spray pipe, some of the impurities it carries will be deposited in the pipe, and some will adhere to the nozzle, thereby causing the flow of the water to be obstructed and the nozzle to be blocked, resulting in the need for regular cleaning or maintenance of the spray pipe during use.

[0035] Reference Figure 1-Figure 4 , an improved spray pipe, including a main pipe 1, a main pipe 2 13 and a water treatment mechanism 7, the main pipe 1 and the main pipe 2 13 are stacked and arranged, and the outer wall of the main pipe 1 facing downward is annularly opened with a branch hole 1, the inside of the branch hole 1 is fixedly connected to a branch pipe nozzle 1 4, the outer wall of the main pipe 2 13 facing downward is annularly opened with a branch hole 2, and the inside of the branch hole 2 is fixedly connected to a branch pipe nozzle 2 11, the branch pipe nozzle 2 11 and the lower spray surface of the branch pipe nozzle 1 4 are at the same height, the water treatment mechanism 7 includes a treatment box 701, and one side of the treatment box 701 A motor frame 707 is fixedly connected to the inside of the motor frame 707, and a driving motor 702 is fixedly connected to the inside of the motor frame 707. The output shaft of the driving motor 702 is fixedly connected to the rotating shaft 712 through a coupling. One end of the rotating shaft 712 is connected to the inner wall of one side of the processing box 701 through a bearing. The outer wall of the rotating shaft 712 is fixedly connected to the filter plate 706. A water guide hole is opened on the side of the processing box 701 facing the main pipe 1, and a diversion pipe 8 is fixedly connected to the inside of the water guide hole. The two diversion ports of the diversion pipe 8 are respectively plugged into the inside of the main pipe 1 and the main pipe 2 13.

[0036] In a specific application scenario, when the water entering the main pipe 1 and the main pipe 2 13 passes through the treatment box 701, the filter plate 706 filters it. After the filter plate 706 has been used for a period of time, the hydraulic cylinder 2 709 is adjusted to drive the upper and lower ends of the blocking semicircle 710 to block the water guide hole and the water inlet hole, and then the drive motor 1 702 is started. The drive motor 1 702 drives the filter plate 706 to rotate in the treatment box 701. During the rotation, the water retained in the treatment box 701 flushes the filter plate 706, thereby removing the impurities attached to it. At the same time, during the rotation of the filter plate 706, the filter plate 70 6 contacts and squeezes the brush plate 705 at the corner, thereby further improving the scrubbing effect of the filter plate 706. After the scrubbing is completed, the hydraulic cylinder 1 708 drives the triangular guide plate 703 to move downward, and the impurities and water in the processing box 701 fall from the processing box 701, completing the cleaning of the filter plate 706.

The filter plate 706 can continue to be put into use to filter the water, avoiding impurities in the water from causing blockage of the branch nozzle 2 11 and the branch nozzle 1 4, thereby improving the use value of the spray pipe.

[0037] Specifically, during the contact between the brush plate 705 and the filter plate 706, the return spring rod 711 is compressed. After the brush plate 705 contacts and squeezes the filter plate 706, the filter plate 706 separates from the brush plate 705, and the return spring rod 711 drives the brush plate 705 to reset, so that the brush plate 705 can continue to brush the filter plate 706, while also avoiding damage to the brush plate 705 and the filter plate 706 caused by excessive contact and squeezing force between the brush plate 705 and the filter plate 706.

A pulling spring rod 2313 is fixedly connected to the side of the top opening piece 2306 facing the inside of the ring frame 2301 at equal distances, and one end of the pulling spring rod 2313 is fixedly connected to the inside of the ring frame 2301. A middle hole is opened at the bottom of the ring frame 2301, and an air intake pipe 21 is fixedly connected to the inside of the middle hole. The open end of the air intake pipe 21 is located outside the tower body 17, and the outer wall of the air intake pipe 21 is connected to the air valve 29 through a flange.

[0045] Specifically, after the gas is introduced into the ring frame 2301, the drive motor 2311 is started, and the drive motor 2311 drives the two rotating plates 2312 to rotate. The gas gradually flows into the packing layer 28 through the gap between the two rotating plates 2312, so that the gas flows evenly to various positions of the packing layer 28, achieving uniform distribution of the gas and ensuring that the gas can fully contact the water in the packing layer 28.

[0046] It should be noted that when the interior of the tower body 17 is cleaned, the packing layer 28 is removed from the tower body 17, the hydraulic cylinder 3 12 is adjusted to drive the expansion guide cloth 5 to move below the main pipe 1 and the main pipe 2 13, the electric telescopic rod 14 is adjusted to drive the extension expansion rod 16 to move outward, and the expansion guide cloth 5 is gradually expanded. Then, the cylinder 1 2302 is adjusted to drive the limiting slider 2303 to move in the limiting guide rail 2304, and the telescopic sealing belt 2305 is expanded to seal the open ends above the two rotating pieces 2312. Then, the cleaning liquid is introduced into the main pipe 1 and the main pipe. In the pipe 2 13, the cleaning liquid flows to the inner wall of the tower body 17 under the action of the unfolded guide cloth 5. At the same time, the gas is continuously introduced into the ring frame 2301 through the long air inlet pipe 21. The upper part of the ring frame 2301 is in a sealed state, and the gas impacts the top opening piece 2306, pulling the spring rod 2313 to be stretched, and the gas flows out along the top opening piece 2306. The gas is directed to the inner wall of the tower body 17. Along the inner wall of the tower body 17, the cleaning liquid from top to bottom and the gas from bottom to top cooperate to achieve effective cleaning of the inner wall of the tower body 17, thereby improving the use value of the cooling tower.

[0047] Working principle: When in use, open valve 1 and valve 2, and water is sprayed out through branch nozzle 1 4 and branch nozzle 2 11. Part of the water falls directly into the packing layer 28, and part of the water is collected by the water collecting bucket, and then slides down the slope of the middle guide cone 2204 to various positions of the water distribution bucket 2201 to achieve preliminary dispersion. Part of the water falls along the middle position through the through hole 2211. At the same time, the air pump 2205 is started. The air pump 2205 guides the gas located at the periphery of the water distribution bucket 2201 into the middle leakage cover through the air collecting ring pipe 2202, and then through each inclined upward nozzle The air hole 2210 sprays out, causing the water sliding down the slope of the middle guide cone 2204 to fall in a parabolic curve, further improving the uniformity of water distribution, and the water falls evenly into various positions of the packing layer 28. After the gas is introduced into the ring frame 2301, the drive motor 2311 is started, and the drive motor 2311 drives the two rotating pieces 2312 to rotate. The gas gradually flows into the packing layer 28 through the gap between the two rotating pieces 2312, so that the gas flows evenly to various positions of the packing layer 28, the gas is fully in contact with the water, and the cooling tower starts to work.
