Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a closed cooling tower spray pipe which can be automatically cleaned. Background Art

[0002] The principle of a closed cooling tower is to circulate the working fluid in the coil of the closed cooling tower. The heat of the working fluid is dissipated through the coil into the spray water flowing through the outer surface of the coil. At the same time, the air outside the unit enters from the air inlet grille on the chassis, opposite to the flow direction of the water, and flows upward through the coil. A small part of the water evaporates and absorbs heat. The hot and humid air is discharged into the atmosphere by the fan at the top of the cooling tower, and the rest of the spray water falls into the water pan at the bottom, which is recirculated to the water distribution system by the spray pump and then sprayed back onto the coil.

[0003] During the long-term operation of the closed cooling tower, dirt such as mud, scale, etc. will appear inside the spray pipe, causing blockage to the spray pipe and the spray head, affecting the spraying effect of the spray water, and further affecting the cooling temperature of the working fluid. Therefore, after the spray pipe has been used for a period of time, it is usually necessary to disassemble the spray pipe for cleaning. This will make it inconvenient to clean and discharge the spray pipe. For this reason, we propose a closed cooling tower spray pipe that can be automatically cleaned. Utility Model Content

[0037] The dredging assembly 3 includes an installation cavity 31 symmetrically opened at the side end of the cleaning block 210, and after the cleaning block 210 moves down to the upper side of the orifice plate 212, each installation cavity 31 corresponds to the position of the water outlet 15, and a dredging block 32 adapted to the water outlet 15 is slidably arranged in the installation cavity 31, and the end face of the dredging block 32 is arranged in an arc shape, so that the dredging block 32 slides into the water outlet 15 and slides out of the water outlet 15. A spring 33 is fixedly arranged between the dredging block 32 and the inner end of the installation cavity 31. Initially, the inner wall of the spray pipe 13 resists the action of the spring 33. Under use, the dredging block 32 is located in the installation cavity 31, and the spring 33 is in a compressed state. After the cleaning block 210 moves down to the upper side of the orifice plate 212, the installation cavity 31 corresponds to the position of the water outlet hole 15. Under the elastic force of the spring 33, the dredging block 32 slides into the water outlet hole 15 to dredge the water outlet hole 15 and further prevent the water outlet hole 15 from being blocked. When the cleaning block 210 moves up, under the resistance of the spray pipe 13 on the dredging block 32 and the setting of the arc-shaped end face of the dredging block 32, the dredging block 32 slides into the installation cavity 31.
