Nozzle capable of achieving atomization under synergy of bubbles

Abstract

The invention belongs to the technical field of nozzles, and particularly relates to a nozzle capable of achieving atomization under synergy of bubbles. The nozzle comprises a shell, at least one rotational flow flow channel and at least one gas injection channel, wherein the shell is provided with at least one liquid inlet and at least one jetting port communicating with the liquid inlet, the rotational flow flow channels communicate with the portion between the liquid inlet and the jetting ports, one ends of the gas injection channels communicate with the flow channel bodies, located betweenthe liquid inlet and the jetting ports, of the rotational flow flow channels, and the other ends of the gas injection channels are suitable for communicating with a gas source. The rotational flow flow channels and the gas injection channels are arranged between the liquid inlet and the jetting ports, atomizing gas is injected in the process that fluid enters the rotational flow flow channels andgenerates rotational flow, after the atomizing gas meets the fluid, the two substances continue rotating and mixing along the rotational flow flow channels, then uniform and stable bubble two-phase flow is generated, the bubbles break up when expanding due to pressure reduction at the jetting ports, and then surrounding liquid forms fine water mist under the shearing and crushing effect of the bubbles. Since the atomizing gas is injected in the rotational flow process, loss of momentum caused during mixing of the atomizing gas and fluid is effectively lowered, and the atomizing efficiency andthe atomizing effect are improved.

Description

technical field [0001] The invention belongs to the technical field of nozzles, and in particular relates to a nozzle capable of cooperative atomization of air bubbles. Background technique [0002] The generation method of fine water mist is generally to achieve the atomization effect by designing a specific mechanical structure in the nozzle shell or the nozzle that can be atomized by air bubbles or by pressurizing the liquid. Common nozzles for fine water mist and bubble cooperative atomization include rotary core, coil spring, obstacle blocking structure, etc., among which the rotary core is the most important spray structure. Its essential function is to make the fluid rotate strongly, and under the action of shear force and centrifugal force, it will generate atomization. [0003] Commonly used spraying methods include direct pressure spraying, gas-liquid two-phase, rotary, hedging, vibrating, and electrostatic atomization. For the direct pressure spraying method, in...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to overcome the defects in the prior art that the nozzles in the prior art use gas-liquid mixing to spray them out directly, resulting in insufficient power of the two-phase flow of the bubbles, resulting in poor atomization effect of the bubbles and insufficient spray intensity, thereby providing a A nozzle capable of synergistic atomization with bubble two-phase flow with sufficient power, good bubble atomization effect and high spray intensity
