螺旋喷嘴又叫脱硫喷嘴、防堵塞喷嘴、大流量喷嘴、除尘喷嘴、耐腐蚀喷嘴，是一种实心锥形或空心锥形喷雾喷嘴，喷流角度范围可为50°-170°。，液体流率范围为5.5-4140升/分。这种结构紧凑的喷嘴有着畅通的流道可以最大程度地减少液体阻塞，使液体在给定尺寸的管道上达到最大流量。
The spiral nozzle is also called desulphurization nozzle, anti blockage nozzle, large flow nozzle, dust removal nozzle and corrosion resistant nozzle. It is a solid cone or hollow cone spray nozzle, and the jet angle range can be 50 degrees -170 degrees. The liquid flow rate ranges from 5.5 to 4140 L / min. This compact nozzle has a smooth flow passage, which can minimize liquid blockage and maximize liquid flow in a given size pipe.
工作原理
working principle
液体（或料浆）通过与连续变小的螺旋面相切和碰撞后，变成微小的液珠喷出而形成雾状。喷嘴腔体内从进口至出口的流线型设计使得阻力系数降至最低，因而螺旋喷嘴适用于各种岗位。例如：化工、环保、电力、纺织等众多工业领域，特别是烟气脱硫除尘行业应用更为广泛。其耐磨性、耐腐性、成雾性、防堵性已被该行业众多用户所接受。
After the liquid (or slurry) is tangent to and collided with the continuously decreasing spiral surface, it turns into tiny droplets and ejects into mist. The streamline design from the inlet to the outlet of the nozzle cavity reduces the resistance coefficient to the minimum, so the spiral nozzle is suitable for various posts. For example: chemical industry, environmental protection, power, textile and many other industrial fields, especially flue gas desulfurization and dust removal industry is more widely used. It has been accepted by many users.
