Spiral spray nozzles provide clog-resistant, wide-area liquid distribution for gas scrubbing, cooling, dust control and process washing. Select the pattern, flow, material and connection from verified operating data.
Description
The spiral nozzle is a solid cone or hollow cone spray nozzle, the spray angle can range from 60 degrees to 170 degrees. Generally used for waste gas washing, flue gas desulfurization, and dust removal industry. Spiral nozzles are also called desulfurization nozzles, anti-clogging nozzles, high-flow nozzles, dust removal nozzles, and corrosion-resistant nozzles. More basic information about nozzles can be found on Wikipedia.
Jeltecn Spraying is a factory with more than 15 years of experience in industrial spray nozzles, we produce full-size spiral spray nozzles and various materials. The production of spiral nozzles has exceeded 1,000,000pcs, advanced machines, mature technology, fast delivery, product quality inspection, etc. are all our advantages.
Spiral nozzles have an unobstructed flow channel design that minimizes liquid blockage and maximizes liquid flow in a given size pipe. Spiral spray nozzles can be installed or retrofitted on most piping systems. Nozzles are available in NPT or BSPT (external) thread types. However, in actual operation, attention should be paid to the selection standard of the length of the nozzle. The impurities in the waste gas and wastewater can pass through the nozzle in large quantities without clogging, which is undoubtedly the best gospel for waste gas and wastewater. Both waste gas and wastewater contain a large number of impurities, and the use of spiral nozzles just solves this problem.

Typically 1/4 inch to 4-inch nozzles can be fabricated from brass, 316 stainless steel casting, PVDF, silicon carbide, TEFLON, or polyvinyl chloride, respectively. For special applications, other materials can also be used. we can also mark your logo on nozzles.

How to Select Spiral Spray Nozzles for Gas Scrubbing
Spiral spray nozzles use a compact spiral impact surface to break liquid into full-cone or hollow-cone coverage with an open flow path. They are commonly evaluated for gas scrubbing, flue-gas desulfurization, gas cooling, dust suppression and wash-down duties where flow capacity, coverage and resistance to plugging are important.
Selection criteria for reliable spray performance
- Liquid and solids: identify chemistry, temperature, suspended-solids size and concentration, specific gravity and viscosity.
- Hydraulic duty: state required flow per nozzle, available pressure at the nozzle inlet and the acceptable turndown range.
- Coverage: define vessel or duct geometry, nozzle quantity, spray angle, overlap and the permitted wall-wetting area.
- Connection and installation: confirm NPT or BSPT thread, male or female connection, orientation, insertion length and maintenance clearance.
- Material: select stainless steel, brass or engineering polymer only after checking corrosion, erosion, temperature and mechanical-load conditions.
Full-cone versus hollow-cone spiral patterns
A full-cone spiral nozzle is generally considered when liquid must be distributed throughout a three-dimensional volume. A hollow-cone spiral nozzle concentrates liquid toward the outside of the cone and may suit perimeter contact or rapid gas cooling. Final selection should be based on the required distribution, droplet behavior and installed geometry rather than spray angle alone.
Engineering and RFQ checklist
For an accurate quotation, provide the process liquid, operating and maximum pressure, target flow, spray angle, connection standard, material preference, solids information, operating temperature, quantity and a drawing or photo of the installation. Jeltecn can then review the requested duty against available industrial spray nozzle types and relevant FGD nozzle selection guidance.
Frequently asked questions
Are spiral spray nozzles clog-proof?
No nozzle is universally clog-proof. The open spiral geometry can improve free passage, but strainers, solids characteristics, nozzle size, cleaning access and operating pressure still determine reliability.
What information is needed to size a spiral nozzle?
At minimum, specify liquid properties, flow per nozzle, pressure at the nozzle, spray angle, connection, material, operating temperature and the required coverage distance.
Spiral Spray Nozzles for Gas Scrubbing: Engineering Decision Guide
Spiral spray nozzles use an open spiral geometry to break liquid into broad full-cone or hollow-cone patterns with relatively unobstructed passages. They are especially valuable in gas scrubbing, flue-gas treatment, quenching and dust control where wide coverage, high flow or reduced clogging sensitivity can outweigh the distribution smoothness of a conventional vane nozzle.
When this nozzle is the right fit
This product is a strong candidate when its spray mechanism matches the process objective and the site can maintain the required utilities, liquid quality, installation geometry and inspection routine. Use the following decision points to qualify the application before selecting a connection or ordering quantity.
| Decision variable | What to confirm |
|---|---|
| Full-cone or hollow-cone duty | Choose a filled pattern for volumetric coverage or a hollow pattern when perimeter interaction and gas-liquid contact are preferred. |
| Droplet requirement | Balance mass transfer or capture efficiency against evaporation, drift, carryover and pressure demand. |
| Spray angle and vessel geometry | Check wall clearance, lance position, overlap and residence path at real operating conditions. |
| Flow and pressure | Confirm liquid availability and pressure at the nozzle after elevation and piping losses. |
| Solids and plugging risk | Provide particle size, concentration and filtration limits; open passages reduce risk but do not eliminate deposition. |
| Corrosion and erosion | Select material from chemistry, temperature, abrasive loading and expected maintenance life. |
How it compares with alternative spray technologies
Compared with a conventional full cone nozzle, a spiral nozzle often provides a more open internal path and can deliver broad coverage with fewer internal components. Conventional vane designs may offer a smoother distribution profile for applications where uniformity is the primary criterion. The best choice depends on plugging risk, distribution tolerance, droplet spectrum, pressure, material and access for maintenance.
Common performance problems and diagnostic checks
| Observed problem | What to investigate first |
|---|---|
| Wall wetting or dry zones | Review angle, lance position, overlap, gas flow and actual spray development. |
| Excess carryover | Evaluate droplet spectrum, gas velocity, nozzle orientation and downstream separation. |
| Erosion or flow drift | Inspect the spiral surface and orifice; compare flow at a controlled pressure with baseline data. |
| Deposit buildup | Review slurry chemistry, shutdown flushing, temperature zones and cleaning access. |
Recommended validation before production release
For scrubber or quench duty, evaluate the nozzle inside the system context: gas velocity, temperature profile, liquid-to-gas requirement, residence time, vessel diameter, lance arrangement and downstream eliminator capacity. Water testing can confirm coverage and flow, but process-liquid properties and hot-gas conditions may change droplet behavior. Final design should be reviewed by the system engineer.
Core-product RFQ checklist
Send the liquid name and concentration, temperature, viscosity, solids or water-quality information, target flow per nozzle, available pressure, air data where applicable, spray distance, coverage geometry, duty cycle, connection preference, material restrictions, installation drawing and photos of the spray zone. State the process result you need and the failure mode you want to avoid. Jeltecn can then review the application and identify points requiring test confirmation.
