[0002] The spray heat exchange tower is a common heat exchange equipment used for heat exchange operations in chemical, electric power, metallurgical and other industrial fields. The spray heat exchange tower is usually composed of a tower body, a spray device, a packing layer, a feed port and a discharge port. The liquid is sprayed to the top of the tower and contacts with the gas, so that the liquid is cooled or heated to achieve heat transfer and mass transfer, and the heat or substance in it is transferred to the gas. In the existing spray heat exchange tower, the nozzle can only work in a single position, which may cause uneven wetting of the packing layer or insufficient contact area. In some cases, the fixed nozzle may cause a dead corner to form in the tower, so that the gas cannot fully contact with the liquid, thereby reducing the heat transfer efficiency.

[0014] The beneficial effects of the utility model are as follows:

[0015] The utility model provides spiral blades in the water outlet pipe, so that during the transmission of liquid, the spiral blades exert a deflection force on the liquid to realize the rotation of the atomizing nozzle.
