Water rotating gas direct spraying type pole plate spraying washing device

Abstract

The invention discloses a water rotating gas direct spraying type pole plate spraying washing device which comprises an outer pipe and a center pipe. The outer pipe is connected with a water tank. The center pipe is connected with a compressed air storage tank. The outer pipe and the center pipe are of a jacket type structure. A gas spraying port is formed in the front end of the center pipe. Compressed air in the center pipe is directly sprayed into a Rafal curved face expansion chamber from the rear portion to the front portion; the conical part of the center pipe is coaxially embedded in the outer pipe in a non-full-contact manner; the inner flow guiding cross section of the outer pipe has a changing process where shrinkage and magnification are sequentially conducted; pressurizing water flows forwards in a conical-cylinder-shaped throttling channel between the outer pipe and the center pipe and enters the Rafal curved face expansion chamber in a rotary spraying manner through a spiral flow channel between a cyclone device and the center pipe; gas and water mixed gas is conveyed to a spraying pipe in front of the gas spraying port due to the Rafal effect; and finally, the mixed gas is jetted out of a spraying port in front of the spraying pipe at high speed. The water rotating gas direct spraying type pole plate spraying washing device is simple in structure, reliable, ingenious and low in cost, the kinetic energy of compressed air can promote gas and liquid to be homogenized and converted into jetting flying power most effectively, and efficient and high-quality electrolysis pole plate spraying washing operation is achieved.

Description

technical field [0001] The invention relates to a polar plate spray cleaning device, in particular to a water cyclone direct injection type polar plate spray cleaning device utilizing the working principle of a Lafal nozzle. Background technique [0002] The spray washing of the electrolytic plate is an indispensable process step in the electrolysis industry. It is currently a more popular way to wash with high-pressure water and chemicals. Its advantages are good washing effect and high water pressure, but there are also problems of large water consumption and energy consumption. Defects, do not conform to the energy conservation and emission reduction policies advocated by our country at this stage. [0003] Therefore, we try to use the working principle of the Rafal nozzle flexibly, and combine the working principle of the rifle barrel to improve the bullet exit velocity, to carry out the direct injection of water cyclone and gas, and realize the direct injection of water...
