Problems solved by technology
[0003] In the waste gas and flue gas desulfurization and dust removal industry, a number of spiral nozzles are generally installed in the waste gas scrubber for waste gas treatment. According to the number of turns of the spiral structure of the spiral nozzle, the adjustment range of the jet flow angle is generally 50°-170°, which is To strengthen the effect of desulfurization and dust removal, the installation in the exhaust gas scrubber is generally achieved by setting up multi-layer and multi-type PP spiral nozzles, but limited by factors such as equipment structure, design cost, processing cost and maintenance cost, it is impossible to clean the exhaust gas. There are too many spiral nozzles with different spray angle parameters in the tower, so it is inevitable that there will be a certain amount of dead spray angle in the space structure in the exhaust gas scrubber, which will affect the desulfurization and dust removal effect

Embodiment
[0034] Such as Figure 1-4The shown PP spiral nozzle for exhaust gas treatment system includes a spray column 1 and a spiral nozzle 2, which is characterized in that: the spiral nozzle 2 includes a nozzle ring 21 connected to the spray column, and a nozzle ring connected to the nozzle ring The lower part of 21 is a tapered four-turn spiral structure 22. The spray column 1 includes an inner spray column 11 and an outer spray column 12 that cooperate with each other. The inner spray column 11 is located in the outer spray column 12, and the inner spray column 11 It is connected with the outer spray column 12 through threads, wherein the outer surface of the inner spray column 11 and the inner surface of the outer spray column 12 are respectively provided with external threads and internal threads that cooperate with each other.
[0035] The inner spray column 11 has a cylindrical hollow chamber, and the outer spray column 12 is radially provided with a receiving platform 3 with ...

The invention provides a PP spiral nozzle for a waste gas treatment system and a spraying method of the PP spiral nozzle. The PP spiral nozzle comprises a spraying column and a spiral nozzle and is characterized in that a tension spring tube is connected to an adapting stage which is arranged in the spraying column, the tension spring tube is connected with a tension spring which is connected witha slide rod, the slide rod penetrates the tension spring tube to connect with a spiral structure, and the spiral nozzle is slidably connected in a hollow cavity of the spraying column through a nozzle ring. The PP spiral nozzle for the waste gas treatment system and the spraying method have advantages that own number of turns can be changed according to inflow water pressure regulation, a spraying angle and spraying flow are further adjusted, troubles of setting large-range multi-parameter spiral nozzles of different types in a waste gas washing tower are avoided, spraying without dead corners is realized, desulfurization and dedusting effects of spraying are improved, enterprise design cost and later maintenance cost are reduced.
Description
technical field [0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to a PP spiral nozzle used in a waste gas treatment system and a spraying method thereof. Background technique [0002] Spiral nozzles are also called desulfurization nozzles, anti-clogging nozzles, high-flow nozzles, dust removal nozzles, and corrosion-resistant nozzles. They are solid cone or hollow cone spray nozzles. This compact nozzle has an unobstructed flow path that minimizes liquid clogging and maximizes liquid flow for a given size of pipe. Spiral nozzles can be installed or retrofitted on most plumbing systems. The manufacturing materials of the spiral nozzle include brass, stainless steel, PVDF, silicon carbide, PP, etc. The spiral nozzle makes the passing liquid (or slurry) tangent and collide with the spiral surface which becomes smaller continuously with its spiral structure, and then becomes tiny droplets and sprays out to form a mist. The...
