The spiral nozzle shoots the liquid in the spiral into a spiral metal protruding into the outer hole. This breaks the traditional fluid flow into relatively fine many concentric rings would form complete cone-shaped spray patterns. The resulting is an uneven distributed spray pattern rather than a full conical spray pattern.
Spiral nozzles with injection purposes are suitable for injecting fluid into a gas stream rather than into the liquid stream. The flow can be as low as 0.534 l / minute. The design of the spiral nozzle is very natural, and it has the characteristics of anti-blockage resistance, but in practice, we should pay attention to the selection of the nozzle length standards.
Introduction: stainless steel spiral nozzle is also called desulfurization nozzle, anti-blockage nozzle, large flow nozzle, dust removal nozzle, corrosion resistant nozzle, is a solid cone or hollow cone spray nozzle, spray Angle range can be 50-170. Liquid flow rates range from 5.5-4140 litres / min. Such compact nozzles with open flow channels can minimize fluid obstruction and achieve a maximum fluid flow rate on a pipe of a given size.
Spiral nozzles can be installed or updated on most plumbing systems. Nozzles are NPT or BSPT (outer) type. Usually a 1 / 4-inch and 1 / 4-inch nozzle can be manufactured from brass, 316 stainless steel casting, PVDF, silicon carbide, TEFLON PTEF, or PVC materials, respectively. If required to be used in special fields, other materials can also be used.
Structure: the nozzle has internal and external threads. Usually 1 / 4 inch to 6 inch spray heads can be made from brass, 316 stainless steel casting, TEFLON PVC, or PVC material, respectively. If required to be used in special fields, other materials can also be used.
Working principle: liquid (or slurry) through the continuous small spiral surface shear and collision, into a small liquid beads ejected and form a fog. The streamlined design of the nozzle cavity is inlet to minimize 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 flue gas desulfurization and dust removal nozzle is more widely used. Its wear resistance, corrosion resistance, fog resistance, blocking resistance has been accepted by many users in the industry.
Scope of application: 1, waste gas washing; 2, gas cooling; 3, washing and bleaching process; 4, fire prevention and fire fighting; 5, used in flue gas desulfurization system; 6, used in dust removal and dust removal system.
Characteristic: 1. Different from the conventional: the conventional solid nozzle has a blade inside, let the liquid through the diversion of the blade to form a clockwise or counterclockwise flow in the same direction, and the water pressure makes the liquid centrifugal force, resulting in a conical spray. The spiral nozzle is different, the spiral nozzle is a typical impact dispersion spray, no structure inside the nozzle, is a smooth channel, the water flow is through the layered interface of hitting the spiral, so that the product layered spray. 2. Not easy to plug: just because the spiral nozzle does not have an internal structure, the impurities in the waste gas and waste water can be greatly passed through the nozzle without causing blockage, which is undoubtedly the best Gospel for the waste gas and waste water, the waste gas and waste water contains a large number of impurities, and the use of the spiral nozzle just solves this problem.3. Multi-layer spray: Regular 120-degree spiral nozzles have three to four spray layered interfaces, and some other angles even have many layers. The effect of spray is: each interface forms a cone spray surface, just think, a spiral nozzle is less than 3-4 cone spray surface, more than 6-7 spray surface, this is the effect of ordinary solid cone nozzle. 4. Many models: in terms of the injection Angle, The spiral nozzle has 60 degrees, 90 degrees, 120 degrees, 150 degrees, 170 degrees, etc.; In terms of the spray mode, Plastic Spiral nozzle has hollow taical direct injection, solid tapered direct injection, hollow tapered tangential type, hollow tapered double injection; In terms of size and size, Plastic Spiral nozzle from 1 / 4 inch to 4 inch; In terms of traffic size, From 5.5 l / min to 4,140 l / min under 3 kg pressure; In terms of materials, Spiral nozzles include PP, PVC, Nylon, PE, Sai Steel, PVDF, PTFE, TELFON, F4, ceramic, 304 stainless steel, 316 stainless steel, 316L stainless steel, silicon carbide, etc.
5. Low cost: the cost of using the spiral nozzle is low, the spiral nozzle mostly uses injection molding, casting, kiln sintering and other processes, in the final analysis is the use of mold manufacturing products, much cheaper than the ordinary metal nozzle cost, and easy to produce large quantities of goods.
