Jet Hybrid Scrubber Tower
A next-generation wet scrubber utilizing jet-ejection fluid dynamics to self-inhale process gases and generate intensive turbulent mixing, delivering acid-gas and dust removal efficiencies of >=95% with zero clogging.
Designed around actual process conditions
Traditional packed-bed scrubbers often suffer from high pressure drops, narrow operational turn-down ratios, and frequent packing calcification or clogging. The FluxFine Jet Hybrid Scrubber Tower bypasses these limitations by leveraging advanced venturi jet-ejection. By using high-velocity liquid sprays to induce a natural draft, the tower self-inhales process gas without requiring an upstream draft fan under low-resistance conditions. This fluid dynamic mechanism generates intense gas-liquid contact, creating large interfacial surface area for high-efficiency absorption and particulate scrubbing (>=95%) while completely eliminating internal packing-bed clogging.

How it works
The scrubber leverages venturi fluid dynamics. High-pressure scrubbing liquid is pumped through specialized spray nozzles, ejecting a high-velocity, wide-angle water cone. This fast-moving liquid stream creates a strong localized negative pressure (draft) within the venturi chamber, drawing the raw process gas into the jet-ejection throat. As gas and liquid merge at high velocity, the organic mist, acid fumes, and particulates are forcefully impacted, absorbed, and hydrated. The mixed fluid then enters a tangential cyclonic separator. Centrifugal forces separate the liquid slurry (which drains to the sump) from the clean, stripped gas, which rises to the demister and exits the stack.
- 01Raw process gas draft induction via the venturi throat negative-pressure zone.
- 02High-velocity liquid ejection forming a dense mist cone to envelop incoming process air.
- 03Intense turbulent mixing and hydration, capturing acid gases and particulate matter.
- 04Tangential cyclonic separation to split the clean gas from the pollutant-laden scrubbing liquid.
- 05Gravity draining of spent liquid into the recirculation sump for filtration or pH dosing.
- 06Venting of purified, de-misted clean gas directly to the atmosphere.
- Inlet air conditioning of explosive, sticky, or highly particulate-laden streams (such as metal polishing dusts, foundry emissions, or paint overspray).
- Abatement of highly soluble acid fumes (HCl, HF, HNO3, SO2, NH3) in chemical and metallurgical processes.
- Pre-filtration of tar and oil droplets to protect downstream thermal oxidizers or carbon beds.
- Plants requiring compact scrubbing units with minimum mechanical components and low maintenance.
- Nozzle condition must be monitored; particulate buildup in the scrubbing loop can clog the high-pressure nozzles, requiring robust primary liquid filtration.
- Proper liquid-to-gas ratios (L/G) must be maintained; a drop in recirculation pump pressure will reduce gas suction capacity and compromise efficiency.
- System pH must be dynamically adjusted (e.g., adding NaOH for acid gases) to ensure consistent chemical absorption.
- For abrasive dusts, periodic wall-thickness checks of the venturi throat are recommended to manage localized erosion.

When is a wet scrubber used before VOC treatment?
It can cool or remove acid/alkali gas, soluble contaminants and certain mist/particulate so that the downstream adsorption or oxidation equipment is protected.
What happens to the scrubber liquid?
It is recirculated with controlled make-up and blowdown. The project must define chemical dosing, wastewater treatment and disposal responsibilities.
Source basis: VOCs equipment source. Materials, reagent and performance are selected from the gas chemistry.
Specific product Q&A
How does a jet scrubber remove sticky particulate better than a packed tower?
Standard packed towers rely on high surface area packing media (like Pall rings) to facilitate gas-liquid contact. However, sticky particulates or viscous aerosols will quickly agglomerate on this media, causing severe plugging and skyrocketing pressure drops. A Jet Scrubber operates completely without internal packing. Instead, it utilizes high-pressure venturi-style jet nozzles to atomize the scrubbing liquid, creating a dense curtain of high-velocity micro-droplets that physically collide with and encapsulate the sticky particulate before washing it into the sump.
What is the liquid-to-gas ratio for a high-velocity jet hybrid scrubber?
Because a Jet Scrubber relies on extreme turbulence and droplet collision rather than wetted surface area, it typically requires a significantly higher Liquid-to-Gas (L/G) ratio compared to standard packed beds. Ratios often range from 3 to 10 L/m³ depending on the target pollutant's solubility, the required scrubbing efficiency, and the density of the particulate loading. FluxFine precisely engineers the recirculation pump sizing to optimize this ratio while minimizing power consumption.
Can a jet scrubber handle high-temperature industrial flue gas?
Yes. Jet Scrubbers are exceptional as primary quenchers for high-temperature flue gas (often exceeding 500°C) from industrial boilers, incinerators, or furnaces. The high-volume liquid jets instantly cool the gas through adiabatic evaporation, simultaneously scrubbing out acid gases (like SO2 and HCl) and heavy particulates. For these extreme applications, FluxFine constructs the scrubber using specialized high-temperature, corrosion-resistant alloys (e.g., Hastelloy, Titanium) or heavily lined carbon steel.
