Novel spraying nozzle without air-resistance and spray forming method thereof

Abstract

The invention relates to a novel spraying nozzle without air-resistance and a spray forming method thereof. The novel spraying nozzle comprises a nozzle base and a jet flow ejector, wherein the nozzle base comprises a base body and a cavity, and the cavity comprises a first fluid channel and a second fluid channel which are formed in the nozzle base; the jet flow ejector comprises a jet pipe bodyand a Raoul pipe type jet pipe cavity thereof, wherein the jet pipe cavity comprises a reducing tapered drainage section, a narrow mixed section and a diverging inverted tapered jet section; the first fluid channel and the second fluid channel are collected on the tail end of the reducing tapered drainage section of the jet pipe cavity, and first fluids of the first fluid channel and second fluids of the second fluid channel are sufficiently mixed on the narrow mixed section of the jet pipe cavity and are jetted by the diverging inverted tapered jet section in an atomizing way, therefore the invention has the effects of no blockage and no air-resistance and is suitable for freely regulating mixed media in any proportion.

Description

technical field [0001] The present invention relates to a new air mist nozzle without air resistance and an air mist forming method, especially relates to the use of air-water mixture as a medium in iron and steel metallurgy and machinery manufacturing industries for cooling, cooling, dust removal, and humidification in metallurgical solidification and heat treatment processes An aerosol nozzle and an aerosol forming method for other occasions. Background technique [0002] The air mist nozzle has been widely used in the cooling control of the secondary cooling zone of metallurgical continuous casting, spray quenching, dust removal, and humidification in the heat treatment process of large castings and forgings. The cooling intensity and humidification amount can be adjusted by adjusting the gas-water ratio in proportion. indicators, and has become a very convenient and reliable method. [0003] The working principle of traditional aerosol nozzles is usually to mix two flui...

AI Technical Summary

Problems solved by technology

However, for the production of alloy steel and high-carbon steel, due to the weak cooling intensity required by the process, the amount of water spray is low, and the high-pressure air creates a barrier to the cooling water, that is, an air barrier, which often prevents the cooling water from flowing out normally.

[0005] In addition, as the most common cooling medium, industrial production water is used in a large amount, and the application environment is poor, resulting in relatively poor water quality. In addition, the presence of inherent mineral salts in the water makes it very difficult even if comprehensive circulating water treatment and filtration are adopted. It is difficult to ensure that the faucet will not be blocked when there is an air barrier. In the high-temperature environment of metallurgical production, especially under low-flow and weak cold conditions, impurities and scale in the water often cause the faucet to be blocked.
