[0002] The spiral nozzle is also called desulfurization nozzle, anti-clogging nozzle, high-flow nozzle, dust removal nozzle, corrosion-resistant nozzle. It is a solid cone or hollow cone spray nozzle. This compact nozzle has a smooth flow channel that can minimize liquid blockage and achieve the maximum flow rate of liquid on a pipe of a given size. The spiral nozzle can be installed or updated on most piping systems. The manufacturing materials of the spiral nozzle include brass, stainless steel, PVDF, silicon carbide, PP, etc. The spiral nozzle allows the liquid (or slurry) to pass through the spiral surface that continuously decreases with its spiral structure. After being tangent and collided, it becomes tiny liquid droplets and sprays out to form a mist. The streamlined design from the inlet to the outlet in the nozzle cavity minimizes the resistance coefficient, so the spiral nozzle is suitable for various positions. For example: chemical industry, environmental protection, electric power, textile and many other industrial fields, especially the exhaust gas flue gas desulfurization and dust removal industry is more widely used.
