Novel rotational flow atomization apparatus and application technology

Abstract

The invention relates to a novel rotational flow atomization apparatus and an application technology. The structure characteristics of a core unit, namely a novel rotary sprayer is that the upper part, connected with fluid, of the rotary sprayer is fixed, the lower part of the rotary sprayer is connected with the upper part through one or a plurality of nozzles by virtue of bearings, the lower part of the sprayer is pushed to rotate at high speed by reactive force formed when a part of kinetic energy of the fluid under pressure is ejected from the nozzles, and meanwhile, most of kinetic energy can be effectively converted into surface energy which can facilitate water flow atomization when impacting the bevel or oblique seam of the sprayer or passing through a hole. The novel sprayer has the advantages that the use pressure is low, the rotating speed is rapid, fogdrops are small and uniform, and the fog spraying coverage area is large. The novel rotational flow atomization apparatus can be applied to extinguishment, black smoke can be instantaneously eliminated, fire head is suppressed in seconds, and big fire can be extinguished within ten seconds; when the novel rotational flow atomization apparatus is applied to flue gas purification, rotational flow like tornado can be produced in a tower, and high-efficient desulfurization dust removal is realized; the novel rotational flow atomization apparatus can be widely applied to city purification, park green space watering, landscape decoration, and crop watering, fertilization, pesticide application and industrial mixing, separating, mass transfer and heat transfer processes, and the circumjacent PM 2.5 and other gaseous pollutant can be effectively removed.

Description

technical field [0001] The invention relates to a new type of swirl atomization device and application technology that can generate high-speed rotation and atomization by means of the fluid's own power, which can significantly improve the process intensification effect, and can be widely used in fluid atomization, flue gas and air purification, spray drying or Industrial and agricultural fields such as concentration, smoke elimination and fire extinguishing. Background technique [0002] Spray technology is widely used in mass transfer and heat transfer processes such as concentration, drying, absorption, flue gas and air purification. The traditional atomization technology uses gas as the continuous phase and liquid as the dispersed phase. Pressurized fluid is pressed into the pores of the nozzle to cause high-speed flow atomization. This technology has a large kinetic energy loss due to the frictional resistance generated by the liquid passing through the pores. There are...

AI Technical Summary

Problems solved by technology

The kinetic energy loss of various existing fixed atomizing nozzles is large, and the atomization effect is not ideal

Although the use of high-speed rotation of the motor can improve the dispersion effect, there are many problems such as high cost, complex structure, high energy consumption, and limited application range, making it difficult to popularize
