Because the development history of nozzles is relatively short, there are no national standard parameters and names for nozzles now. Air atomizing nozzles are also called dual-fluid atomizing nozzles. Usually, two parts of air and liquid work together, and then according to the internal structure design of the nozzle, the liquid is It is evenly…
In the fire protection system, the water mist nozzle uses high pressure to make nitrogen and water rotate at high speed in the nozzle to form water particles or water mist. Water mist is easy to gasify after encountering fire. Everyone knows that nitrogen does not support combustion, so the water mist containing nitrogen can…
Siphoning is a hydrodynamic phenomenon that draws liquids without the use of a pump. A siphon atomizing nozzle produces a finer droplet spray by increasing the gas pressure or decreasing the liquid pressure, resulting in a higher gas flow rate to liquid flow rate ratio. The fine droplet spray produced by the siphon atomizing nozzle…
The reason why the atomizing nozzle does not spray is analyzed. The atomizing nozzle is designed according to its working under a variety of different spraying conditions. Therefore, only by selecting the appropriate atomizing nozzle can good spray performance be obtained during use. The characteristics of an atomizing nozzle are mainly reflected in its spray…
There are many types of nozzles, the core components of the atomization system, and the degree of atomization is different. Generally, the customer requirements are that the smaller the atomized particles, the better, so how to get the desired degree of atomization? Two aspects of the nozzle will talk about how to reduce the particle…
To put it bluntly, the environmental protection dust-removing and dust-removing fog cannon uses high pressure to break the liquid water into very fine particles, which are as fine as the floating dust particles in the air, so that they are held together into a ball, so as to achieve the effect of dust removal. The…
Coal loading and unloading dust production points: 1) Dock belt conveyor belt head. The material falls into the downstream chute along the belt. Due to the release of the potential energy of the falling material, the material rebounds after the side wall of the chute, and continuously collides with the material that falls later, generating…
High-pressure water mist, also known as micro-water mist, has a pressure greater than 10MPa. It is based on a positive displacement pump, usually a plunger pump, and the system pressure can reach up to 100-200MPa. The high-pressure water mist system and device are generally safe, economical and efficient, and the pressure is usually 10-20MPa. High-pressure…
The performance of the nozzle has an important influence on the desulfurization rate. At present, 5 kinds of nozzles are usually used in the wet spray layer desulfurization tower: hollow cone tangent nozzle, solid cone tangent nozzle, double hollow cone tangent nozzle, solid cone nozzle and spiral nozzle. There are two types of commonly used…
1. Single-fluid nozzle: The nozzle of this structure is designed to use the pressure difference of the ejected medium to accelerate the ejected medium to a certain ejection speed at the nozzle mouth, so that the liquid is blown away under the eddy current effect and the interaction with the surrounding air. It erupted, perhaps…
