The evaporative heat exchanger rotary nozzle developed by Luoyang Longhua Heat Transfer Energy Saving Co., Ltd. has recently obtained a national utility model patent.
This rotatable nozzle makes the spray water form a uniform water film on the surface of the heat exchange tube and exchange heat with the process fluid in the tube. The utility model solves the problems of poor water atomization effect, small water area, and unequal thickness of the water film formed on the surface of the heat exchange tube, etc., and a cloth that is commonly used in the evaporative heat exchange equipment, such as a spiral nozzle or a basket type nozzle. The uneven distribution of water caused by uneven water quality and poor heat transfer problems.

There have two type screw pumps: 1. Single Screw Pump. 2. Three Screw Pump 1. single screw pump usually been used to transfer sludge, mud, sauce etc thick liquid. 2. three screw pump usually beed usde to transfer the temperature not higher than 150 degree diesel fuel oil, lubricating oil etc oil. and heat insulation triple Screw Pump beed used to transfer bitumen, heavy oil etc, pump can bear 300 degree high temperature.
