Embodiment Construction

[0021] Below in conjunction with accompanying drawing and embodiment the present invention is described in detail.

[0022] Such as Figure 1a , 1b As shown in the figure, it is used for the anti-wall flow nozzle of the cooling tower, which consists of two parts: the main body of the nozzle and the fixed sleeve. The main body of the sprinkler head includes a water inlet 1, a fixed pin 3, a conical central diversion channel 2, a splash plate 4 on the back of the sprinkler head, a first layer splash plate 5, a second layer splash plate 6, a third layer splash plate 7, The fourth floor splash board 8, edge sawtooth 9.

[0023] Such as Figure 4a , As shown in 4b, the fixed sleeve includes a coupling port 13 connected with the water distribution pipeline, a handle 10, a guide pin groove 11, and a fixing hole 12.

[0024] The fixed sleeve is cylindrical, with a total length of 45~60mm. It is divided into two parts, the upper part and the upper part. 3mm, connected with the wate...

Abstract

The invention relates to a nozzle for cooling tower wall-defense flow. The upper part of the fixed sleeve is fixedly connected with the water distribution pipe, and the lower part is positioned and fixedly connected with the water inlet at the upper end of the nozzle main body. There is a back water baffle, and in the middle of the back water baffle, four splash boards are sequentially arranged from top to bottom, and each splash board is provided with a sawtooth edge of the splash board. The spraying area of ​​the nozzle is semicircle, and a circle of anti-wall flow nozzles is arranged directly above the edge of the cooling tower packing, and the position of the nozzle is fixed so that the spraying area falls on the packing. The combination of the two nozzles can effectively reduce the generation of wall flow , At the same time, it can avoid the problem of no spray water in some areas of the filler due to the change of the flow rate of the nozzle. The invention can avoid the occurrence of wall flow, even if the flow rate changes, there will be no wall flow, the possibility of no spray water area is greatly reduced, the overall spray is more uniform, and the cooling capacity of the tower is obviously improved.

Description

technical field [0001] The invention relates to a spray head of a cooling tower, in particular to a spray head for preventing wall flow. Background technique [0002] The cooling tower industry has developed well in China and has been widely used in national life and industrial production. According to the contact mode between cooling water and air, it can be divided into open cooling tower and closed cooling tower, referred to as open tower and closed tower, whether it is The main heat dissipation methods of open tower or closed tower include contact heat dissipation and evaporative heat dissipation, among which evaporative heat dissipation is dominant. [0003] The quality of the spraying effect is an important factor determining the cooling capacity of the cooling tower. The generation of wall flow will reduce the cooling effect of the cooling tower. The spray water along the wall does not participate in the heat dissipation of the filler, and basically does not get coole...
