QX swirling atomizing nozzle is a new type of jet element. The design utilizes swirling atomization to integrate the internal and external mixing and collision mechanisms of gas-liquid two-phase flow. It uses liquid mist flow to inject the atmosphere to enhance the spray effect. The spray injector is designed in a critical state. Therefore, it has a series of advantages such as good atomization effect, large injection air volume, low working water pressure (0.03~0.15Mpa), large flow rate, large flow channel that is not easy to be blocked, stable working performance, and easy installation and disassembly. Compared with ordinary pneumatic atomizing nozzles, this nozzle does not require an external air source and can form good water mist by relying on its own self-priming gas. ； Compared with pressure centrifugal nozzles, it has the advantage of low working water pressure. At the same time, it has the advantages of large flow, simple structure and low price that the two do not have. Because it does not require external compressed air and high working water pressure, and has the advantage of atomization under large flow conditions, the QX-type nozzle opens up new application areas for spray technology and makes some heat transfer equipment look brand new. It can be widely used in spray cooling, evaporation, gas-liquid reaction, wet dust removal, degassing and other equipment systems. Since the advent of this nozzle, it has been rapidly applied in equipment and processes such as gas scrubbers, desulfurization towers, spray cooling towers, jet condensers, vacuum deoxygenation, and condensate water recovery. High-tech products such as spray propulsion atomization devices have been developed, which have achieved the effect of increasing production and saving energy, creating great social and economic benefits, and have won praise from users. Nozzle structure and working principle: Low-pressure water enters the spherical swirl chamber tangentially from the water inlet pipe. The rotating water is ejected in the form of a rotating jet through a carefully designed water nozzle. The rotating jet is a hollow film flow that injects air from the air inlet for air-water mixing. Under the action of centrifugal force and gravity of the ejection air rotation, the liquid film is torn apart to form a spray flow.
