Gas phase auxiliary atomizing nozzle with built-in magnetization structure and atomizing method

Abstract

The invention discloses a gas phase auxiliary atomizing nozzle with a built-in magnetization structure and an atomizing method. The gas phase auxiliary atomizing nozzle comprises a cylindrical shell. A liquid inlet is formed in the first end of the shell, and a cyclone outlet is formed in the second end of the shell. An air inlet is formed in the middle of the side wall of the shell, the liquid inlet is provided with a tapered inner flow channel, the tapered inner flow channel communicates with the liquid inlet and a bubble-shaped flow outlet, an aeration hole is formed in the side wall of a diffusion section of the tapered inner flow channel, a magnetization cavity is formed in the outer side of the diffusion section, and a magnetization ring is arranged in the magnetization cavity. An air cavity is formed at the outer side of the magnetization cavity and the outer side of the aeration hole section, the air cavity communicates with the air inlet and the cyclone outlet, and the aeration hole communicates with the air cavity and the tapered inner flow channel. The bubble-shaped flow outlet communicates with the cyclone outlet. Rotational flow channels are uniformly arranged in the air cavity in the circumferential direction. The volume of a pre-magnetizer placed at the liquid inlet of the nozzle is reduced, the magnetization distance is shorter, the application scene is more flexible, the physical and chemical effect is better, and the gas phase auxiliary atomization condition and cost are reduced.

Description

technical field [0001] The invention belongs to the technical field of gas-liquid two-phase flow atomization, and in particular relates to an atomization method of a gas-phase auxiliary atomization nozzle with a built-in magnetization structure. Background technique [0002] As an efficient liquid breaking technology, atomization technology has been widely used in various fields. For example, atomization therapeutic devices are widely used in the medical process to produce easily absorbed drug particles; dust suppression spray technology is used in mines to reduce air particles that are extremely harmful to workers; spray technology is used in the artificial cooling process, and the cooling speed is faster than that of air conditioners , with a larger range. [0003] The atomization technology mainly relies on the design of the atomization nozzle, and the pros and cons of the atomization nozzle largely determine the advancement of the atomization technology.

Problems solved by technology

[0006] For the existing gas-phase atomization nozzles, the air pressure of the bubble atomization nozzle is relatively high, and the air consumption of the pneumatic atomization nozzle is relatively large, neither of which can achieve low-cost and high-efficiency atomization

However, the existing magnetization equipment is large in size and high in cost, and cannot be applied on a large scale.
