Atomization system based on flow focusing technology

Abstract

The invention discloses an atomization system based on a flow focusing technology, and relates to the technical field of atomization. The atomization system includes a liquid storage tank, a peristaltic pump, an air pump and a two-fluid spray head device; the bottom of the liquid storage tank communicates with one end of a first connecting pipe; and the other end of the first connecting pipe penetrates through the peristaltic pump and communicates with an liquid inlet pipe of the two-fluid spray head device. According to the atomization system based on the flow focusing technology, spray liquid in the liquid storage tank is delivered to the two-fluid spray head device by the peristaltic pump, while the air pump delivers gas to the two-fluid spray head device, the spray liquid flowing fromthe two-fluid spray head device is driven by the high-speed flowing gas, and a micro jet is formed at the top of the cone, the micro jet is broken into monodisperse micro drops at a certain distance outside a small hole, and thus atomized droplets on the micro nanometer scale are formed; the process can be applied to all kinds of liquid with different viscosity and fluidity, the dispersion effectof the spray liquid is effectively improved, the absorption efficiency of animals and plants for small droplets is facilitated, and the action effect of the liquid is enhanced.

Description

technical field [0001] The invention belongs to the field of atomization technology, in particular to an atomization system based on flow focusing technology. Background technique [0002] Sprayer or atomizer is a method that disperses the continuous supply of spray liquid into a number of tiny droplets to act on the surface of animals and plants or in the air to achieve functions such as beauty, watering or skin surface sterilization; and tiny droplets It is conducive to the full absorption and utilization of animals and plants, and has a strong effect, so it provides certain convenience for people's life. [0003] There are two ways for the sprayer on the market: 1. Atomization by using a common two-fluid nozzle device: When the spray liquid is discharged through the two-fluid atomizing nozzle and flows through the edge of the nozzle hole, it expands into a liquid spray layer, because the aerodynamic force is not enough. Stable, the spray liquid layer is cracked into elon...

Problems solved by technology

[0006] The purpose of the present invention is to provide an atomization system based on flow focusing technology, which continuously and stably transports the spray liquid in the liquid storage tank to the two-fluid nozzle device through a peristaltic pump, and at the same time, the air pump delivers the gas to the two-fluid nozzle device. In the nozzle device, the spray liquid flowing out of the two-fluid nozzle device is driven by the high-speed flowing gas, and after focusing through the small hole, it forms a stable cone in the conical nozzle, and forms a micro jet at the top of the cone. It is broken into monodisperse droplets at a certain distance outside the small hole, thus forming atomized droplets and particles of micro-nano scale; The problem of atomizing spray liquid into micro-nano-scale droplet particles
