The working principle of the spiral nozzle is: liquid (or slurry) is sprayed out as fine droplets to form a mist after tangentially contacting and colliding with a continuously shrinking spiral surface. The streamlined design of the spiral nozzle cavity from the inlet to the outlet minimizes the resistance coefficient, making spiral nozzles suitable for various applications. For example, they are widely used in many industrial fields such as chemical, environmental protection, power, and textile industries, particularly in flue gas desulfurization and dust removal. Their wear resistance, corrosion resistance, misting performance, and anti-clogging properties have been widely accepted by many users in the industry. Based on the medium sprayed by the spiral nozzle, spiral nozzles are divided into three categories: ceramic, plastic, and metal. Their performance characteristics and application scenarios are listed as follows:

Material Category	Material Name	Characteristics	Application Scenarios
Engineering Ceramic	Alumina Al₂O₃	Density 2.5, bending strength 280, hardness HRA85, temperature resistance 300°C, acid resistance, alkali resistance, temperature resistance	Spraying various corrosive clear liquids or corrosive slurries below 150°C
Engineering Ceramic	Silicon Carbide SiC	Density 3.1, bending strength 320, hardness HRA88, temperature resistance 400°C	Spraying various corrosive clear liquids or corrosive slurries below 300°C, especially in applications requiring high strength and wear resistance.
Plastic	Ultra-High Molecular Weight Polyethylene UHMWPE	Resistant to general acids and alkalis, good wear resistance	Spraying corrosive slurries below 80°C
	Polypropylene PP	Resistant to general acids and alkalis	Spraying corrosive clear liquids below 85°C
	Polytetrafluoroethylene F₄	Excellent corrosion resistance, good self-lubricating properties	Spraying various corrosive clear liquids below 200°C and low-concentration slurries
Metal	304 Stainless Steel	High strength, high temperature resistance, moderate price	Spraying general acid and alkali solutions or slurries (except hydrochloric acid media)
	316, 316L	High strength, good corrosion resistance, higher price	Spraying various highly corrosive clear liquids or slurries
	Cobalt-Chromium Alloy	High strength, high temperature resistance, excellent corrosion resistance, high price	Spraying high-temperature, highly corrosive, and highly abrasive slurries. For example, spraying sulfuric acid agents in thermal power plants
