Mixed-flow type spray propulsion cooling device

Abstract

The invention discloses a mixed-flow type spray propulsion cooling device which comprises a variable-speed cylinder. A water inlet pipe communicating with the variable-speed cylinder is arranged at the lower end of the variable-speed cylinder; a rotating cylinder is rotatably connected to the inner wall of the variable-speed cylinder through a sealing bearing; multiple spray pipes communicating with the interior of the rotating cylinder are installed on the side wall of the rotating cylinder; a liquid inlet pipe and a liquid outlet pipe communicating with the interior of the variable-speed cylinder are installed on the variable-speed cylinder; the ends, away from the variable-speed cylinder, of the liquid inlet pipe and the liquid outlet pipe jointly communicate with a liquid storage tank; a liquid discharging device for discharging liquid to the variable-speed cylinder is installed in the liquid storage tank; and a baffle is connected into the variable-speed cylinder in a sealed and sliding mode. According to the mixed-flow type spray propulsion cooling device provided by the invention, by arranging the liquid storage tank, the liquid discharging device, the liquid inlet pipe, the liquid outlet pipe and other components, part of water can be guided into the liquid storage tank so as to be stored when the water flow pressure is large, and when the water flow pressure is small, a push plate is pushed through a second spring so as to extrude out water in the liquid storage tank, so that the water flow pressure can be kept stable and balanced, and the cooling tower obtains a stable and effective cooling effect.

Description

technical field [0001] The invention relates to the technical field of cooling tower related equipment, in particular to a mixed-flow spray propulsion cooling device. Background technique [0002] The mixed-flow spray cooling tower is a common cooling equipment in the chemical industry. It can spray cooling water into mist to quickly evaporate and absorb heat. Wherein the spray propulsion device is a very important part, which mainly drives the spray head and the spray propeller connected to it to rotate around the central axis through the kinetic energy of the sprayed water. [0003] This driving method is very dependent on the kinetic energy of the sprayed water flow, that is, the water flow pressure. In the actual use process, the water flow rate changes greatly and the water flow pressure fluctuates. When the water flow pressure is high, the speed of the spray propulsion device is fast and the water body The atomization effect is good and the water mist spraying area is...

Problems solved by technology

[0003] This driving method is very dependent on the kinetic energy of the sprayed water flow, that is, the water flow pressure. In the actual use process, the water flow rate changes greatly and the water flow pressure fluctuates. When the water flow pressure is high, the spray propulsion device rotates fast and the water body The atomization effect is good and the water mist spraying area is wide, but when the water pressure is low, the water mist effect is poor and the spraying area is small, so that the cooling effect of the cooling tower also changes continuously, and the cooling effect is unstable, especially when the water pressure is small, the cooling The effect is very unsatisfactory
