Abstract

The invention discloses a double-fluid differential pressure-free backflow spray gun. The double-fluid differential pressure-free backflow spray gun comprises a gas-liquid mixing three-stage atomization outlet, a liquid phase two-stage atomization outlet, a liquid phase inner pipe, a gas phase inlet, a liquid phase inlet, a gas phase outer pipe and a liquid phase first-stage atomization outlet. The double-fluid differential pressure-free backflow spray gun is characterized in that the liquid phase first-stage atomization outlet is formed in the lower left end of the liquid phase inlet, the gasphase outer pipe is arranged at the left end of the liquid phase first-stage atomization outlet, and the gas phase inlet is formed in the upper end of the gas phase outer pipe. The problem of differential pressure backflow of a double-fluid atomization spray gun in the prior art is completely solved while the atomization effect is not affected. According to the spray gun, the mode that gas and water enter and are separated and are mixed at the outlets is adopted, the inner pipe and outer pipe structure is adopted, compatibility is high, compressed air of the outer pipe can cool a spray head,the temperature resistance is greatly improved, and the service life is greatly prolonged.

Description

technical field [0001] The invention relates to the field of spray gun equipment, in particular to a two-fluid non-differential pressure return spray gun. Background technique [0002] The two-fluid spray gun uses compressed air to atomize water, and the water pressure is relatively low. During normal operation, the air pressure is constant at about 4.5bar, and the water volume is adjusted according to the temperature of the flue gas. [0003] At present, the atomization effect of the existing two-fluid non-differential pressure backflow spray gun is poor, and the problem of differential pressure backflow of the two-fluid atomization spray gun cannot be effectively solved. Contents of the invention [0004] The purpose of the present invention is to provide a two-fluid non-differential pressure return spray gun to solve the problem of poor atomization effect of the existing two-fluid non-differential pressure return spray gun. [0005] In order to achieve the above object...
