Gas Cleaning Nozzles:
Gas cleaning involves removing foreign substances from a gas stream by spraying a responding liquid into the vent gas. Different types of scrubbers require different spray properties, so nozzle selection is critical.
Dust Suppression Nozzles:
Dust contamination is a common hazard in many manufacturing processes. Careful nozzle selection is required to use fine sprays to capture dust once it is in the air or to prevent it from forming in the first place.
Foam-Control Nozzles:
Foam is a common type of contamination that can be controlled by using an appropriate spray. The nozzles required will need to knock back the foam while also providing a healthy level of atomization so that the choking liquid can act on the foam.
Odor Control Nozzles:
Unpleasant odors are a common type of contamination. When located near residential areas, the problem is particularly acute as legislation may require the issue to be resolved. Sprays are a common method for eliminating odors, either by spraying a substance that masks the smell or by capturing and removing odor-causing particles.

Contamination Control through Spray Application - Gas Cleaning
Gas cleaning is a process that involves spraying a liquid into a gas stream to remove impurities or contaminants from the gas. This technique is commonly used in pollution control applications to eliminate gases like CO2 or SO2 from power plant emissions.
In order to maximize contact and reaction speed, fine sprays with large surface area-to-volume ratios are typically required. For smaller gas cleaning applications, P or PJ impingement nozzles may be suitable, as they produce the largest droplets among all direct pressure nozzles. For finer and more responsive sprays, air-atomizing nozzles should be used. However, the XA range of air atomizers may not be effective for gas cleaning applications as they operate at low flow rates. Instead, the twisting air high flow rate air atomizers are a better choice.
Large Gas Cleaning Applications
For larger gas cleaning applications, such as power plant vent gases or when cleaning fast-moving gas streams, the range and energy of the spray must be taken into account. If the spray does not reach the entire gas stream, areas of contaminated gas may form. It is a basic law of physics that sprays with heavier, larger drops have greater reach than finer sprays, which conflicts with the need for large surface area to volume ratio sprays. A possible solution to this problem is to use TF series twisting nozzles, which produce a relatively fine spray with some larger droplets for extended reach.
The basic principle of gas cleaning involves spraying a lime slurry into the gas stream, which reacts with the SO2 to form gypsum that falls to the ground. Our spray nozzles are used in gas scrubbers worldwide, removing thousands of tons of sulfur dioxide from emissions every year. We take pride in our contribution towards preserving the earth's climate and continuously strive to improve the effectiveness of our cleaning nozzles.
Key Spray Applications for Contamination Control - Foam Suppression
Foam is a common contamination in chemical and biological processes. Sprays of foam retardant can be used to suppress the foam. In food production processes, only pure water is typically used as a foam retardant. A suitable nozzle for foam suppression should produce a relatively fine spray with some degree of spray impact.
Examples of foam include:
● Foam from sewage and water treatment plants
● Foam from mixing tanks
● Foam from paper pulp mulches
A common problem in foam-forming conditions is nozzle clogging. Nozzles that are resistant to clogging are recommended for most anti-foam spray applications.
Nozzle Selection
The TF series of twisting full cone nozzles can be considered for foam control, as they provide a wide range of droplet sizes, including some heavier ones that assist with impact, and they are highly resistant to clogging. Alternatively, other axial spin full cone nozzles may also be suitable.
Key Spray Applications for Contamination Control - Dust Suppression
Dust is a common pollutant in many industrial processes that can have severe health effects on workers. Spray nozzles can be used in two broad dust suppression applications. Firstly, sprays can be used on wet surfaces prone to dust production to prevent dust formation (prevention). Secondly, a fine spray can be used to absorb and capture airborne dust (curative dust suppression).
Key Spray Applications for Contamination Control - Odor Control
Odor control is similar to dust control in many respects. A fine liquid spray is used to capture odor-causing molecules instead of dust particles. As odor-causing particles are generally much smaller than dust, the sprays used to capture them require better atomization. This can create issues with spray reach, as finely atomized sprays have less kinetic energy than coarser sprays.
Contamination Control Spray Challenge - Wide Area Spraying
Often, large areas need to be treated. For example, odor control in a landfill site would require spraying over potentially acres of land. This presents significant challenges. If, as is the case with many contamination control applications, the desired spray consists of fine droplets, matters are worse, as fine sprays have less inherent energy.
