Double-fluid atomization sprayer

Abstract

The invention belongs to the filed of design and manufacturing of a hydraulic mechanical sprayer, in particular to a double-fluid atomization sprayer. The double-fluid atomization sprayer comprises more than one nozzle arranged at the front end of the sprayer, wherein each nozzle comprises a fluid flow hole and a gas hole positioned in the nozzle, the fluid flow hole extends to the end surface exposed out of the nozzle of the sprayer to form fluid outlets, the gas hole extends to the end surface exposed out of the nozzle of the sprayer to form gas outlets, both the fluid outlets and the gas outlets are arranged adjacently, the sprayer is provided with fluid inlet holes and gas inlet holes, and the gas inlet holes and the gas holes as well as the fluid inlet holes and the fluid flow holes are connected with each other through respective and independent gas channels or fluid flow channels. By directly spraying high-pressure water and high-pressure gas out of the nozzle, then disturbing the sprayed water by means of the high-pressure gas and producing a gas-in-water effect after water-gas mixing so as to diffuse the water fog, the atomization covering range of the sprayer is wide, and the sprayer can effectively reduce friction among fog particles and has high spray momentum.

Description

Technical field [0001] The invention belongs to the field of design and manufacture of hydraulic mechanical nozzles, and specifically relates to a two-fluid atomized nozzle. Background technique [0002] Two-fluid atomization nozzles are widely used in disinfection, fire protection, pesticide spraying and other fields. The existing two-fluid atomizing nozzles mostly adopt a single nozzle or linearly arranged multi-nozzle structure, which has the following shortcomings: (1) The spray coverage of a single nozzle is small. If you want to use it in a wide range, the amount of on-site pipe network is large. (2) The momentum of the mist is small, and it is often difficult to overcome the air resistance to reach the surface of the spray object. (3) Since the existing nozzles generally adopt the principle of air-assisted water promotion, the negative pressure is formed in the nozzle by the air pressure spray from the air cavity through the nozzle to the outside to absorb the water in th...

Problems solved by technology

[0005] The beneficial effect of the present invention is that: after adopting the above-mentioned structure, the problems of small spray coverage and large pipe network consumption of the existing air-push water nozzles are solved, and the design of multiple liquid outlets and air outlets makes water unnecessary After mixing in the nozzle, the air is forced to push out, but the high-pressure water and high-pressure gas are directly sprayed out of the nozzle, and then the sprayed water is disturbed by the high-pressure gas, and the water-gas is mixed to produce a water-in-water effect to spread the water mist. Go out to form a single nozzle to produce multiple double-flow atomization effects
