Image bafflespray.jpg thumb right 275px Figure 1 Baffle sprayscrubber Baffle spray scrubbers are a technology for air pollution control . They are very similar to spray tower s in design and operation. However, in addition to using the energy provided by the spray nozzles, baffle s are added to allow the gas stream to atomize some liquid as it passes over them. A simple baffle scrubber system is shown in Figure 1 . Liquid sprays capture pollutant s and also remove collected particles from the baffles. Adding baffles slightly increases the pressure drop of the system. This type of technology is a part of the group of air pollution controls collectively referred to as wet scrubber s. A number of wet scrubber designs use energy from both the gas stream and liquid stream to collect pollutants. Many of these combination devices are available commercially. A seemingly unending number of scrubber designs have been developed by changing system geometry and incorporating vanes, nozzles, and baffles. Particle collection These devices are used much the same as spray tower s to preclean or remove particles larger than 10 m in diameter. However, they will tend to plug or corrode if particle concentration of the exhaust gas stream is high. Gas collection Even though these devices are not specifically used for gas collection, they are capable of a small amount of gas absorption chemistry absorption because of their large wetted surface. Summary These devices are most commonly used as precleaners to remove large particles 10 m in diameter .

Image Cyclone separator.svg thumb 200px A simple cyclone separator Cyclonic separation is a method of removing particulate s from an air, gas or liquid stream, without the use of filter air filter s, through vortex separation. Rotation al effects and gravity are used to separate mixtures of solids and fluids. The method can also be used to separate fine droplets of liquid from a gaseous stream. A high speed rotating air flow is established within a cylindrical or conical container called a cyclone . Air flows in a helical pattern, beginning at the top wide end of the cyclone and ending at the bottom narrow end before exiting the cyclone in a straight stream through the center of the cyclone and out the top. Larger denser particles in the rotating stream have too much inertia to follow the tight curve of the stream, and strike the outside wall, then falling to the bottom of the cyclone where they can be removed. In a conical system, as the rotating flow moves towards the narrow end of the cyclone, the rotational radius of the stream is reduced, thus separating smaller and smaller particles. The cyclone geometry, together with flow rate , defines the cut point of the cyclone. This is the size of particle that will be removed from the stream with a 50 efficiency. Particles larger than the cut point will be removed with a greater efficiency, and smaller particles with a lower efficiency ...

In pollution scrubber s, sometimes hot exhaust gas is quenched , or cooled by water sprays, before entering the scrubber proper. Hot gases those above ambient temperature are often cooled to near the saturation level. If not cooled, the hot gas stream can evaporate a large portion of the scrubbing liquor, adversely affecting collection efficiency and damaging scrubber internal parts. If the gases entering the scrubber are too hot, some liquid droplets may evaporate before they have a chance to contact pollutant s in the exhaust stream, and others may evaporate after contact, causing captured particles to become reentrained. In some cases, quenching can actually save money. Cooling the gases reduces the temperature and, therefore, the volume of gases, permitting the use of less expensive construction materials and a smaller scrubber vessel and fan. Design A quenching system can be as simple as spraying liquid into the duct just preceding the main scrubbing vessel, or it can be a separate chamber or tower with its own spray system identical to a spray tower . Quenchers are designed using the same principles as scrubbers. Increasing the gas liquid contact in them increases their operational efficiency. Sizing Small liquid droplets cool the exhaust stream more quickly than large droplets because they evaporate more easily. Therefore, less liquid is required. However, in most scrubbing systems, approximately one and a half to two and a half times the theoretical evaporation demand is required to ensure proper cooling. ref Industrial Gas Cleaning Institute 1975 ref Evaporation also depends on time it does not occur instantaneously. Therefore, the quencher should be sized to allow for an adequate exhaust stream residence time. Normal residence times range from 0.15 to 0.25 seconds for gases under 540 C 1000 F to 0.2 to 0.3 seconds for gases hotter than 540 C. ref Schifftner 1979 ref Recirculation Quenching with recirculated scrubber liquor could potentially reduce overall scrubber ... more details

Context date October 2009 Image ejectorventuri.jpg thumb right 275px Figure 1 Ejector venturi scrubber This type of technology is a part of the group of air pollution controls collectively referred to as wet scrubber s. An ejector or venturi scrubber is an industrial pollution control device, usually installed on the exhaust flue gas stack s of large furnace s, but may also be used on any number of other air exhaust gas exhaust systems. To this end, an ejector venturi scrubber as well as the spray tower uses a preformed spray, the difference is that only a single nozzle is used instead of many nozzles. This nozzle operates at higher fluid pressure pressures and higher injection rates than those in most spray tower spray chambers . The high pressure spray nozzle up to 689 pascal unit kPa or 100 pound force per square inch psig is aimed at the throat section of a venturi effect venturi constriction. The ejector venturi is unique among available scrubbing systems since it can move the process gas without the aid of a blower or fan implement fan . The liquid spray coming from the nozzle creates a partial vacuum in the side duct of the scrubber. This has the same effect as the water aspirator used in high school chemistry labs to pull a small vacuum for filtering precipitated materials due to the Bernoulli effect . This partial vacuum can be used to move the process gas through the venturi as well as through the facility s process system. In the case of explosive or extremely corrosive atmospheres, the elimination of a fan in the system can avoid many potential problems. The energy for the formation of scrubbing droplets comes from the injected liquid.
