venturi scrubber air pollution control

The Monroe Dual Throat Scrubber is one of the most versatile venturi scrubber designs available because of its ability to handle a wide range of dry, wet, sticky, tacky, and oily particulate loads. Waste water disposal problems are eliminated under normal operating conditions. Industrial scrubbers are one of the primary devices that control gaseous emissions, especially acid … Return to all Air Pollution Control Equipment. We specialize in the treatment of particulate and gaseous emissions from industrial sources. These products are available at cost effective market leading price. Venturi scrubbers are also known as venturi jet scr ubbers, gas-atomizing spray scrubbers, and ejector-venturi scrubbers. Scrubbers are devices that use a liquid (often water) to capture and remove pollutants. Functionality of the Venturi scrubber The raw gas enters the Venturi Scrubber through the vertical venturi head (1), in which the scrubbing liquid is induced via open pipes. Distributing the scrubbing liquid over a shelf (Weir) eliminates the use of spray nozzles. However, where the intended use will involve corrosive or highly abrasive contaminants, other construction materials such as stainless steel or reinforced fiberglass, as well as special coatings are available. A spray tower scrubber is a low energy scrubber and is the simplest wet scrubber used for particulate control. The company’s first project in the early 1970’s was a pilot venturi scrubbing system designed to remove oil and particulate from a contaminated air stream at an automotive manufacturing plant. A venturi scrubber consists of three sections: a converging section, a throat section, and a diverging section. These scrubbers are designed for maximum efficiency and are ruggedly constructed for long service life with minimum maintenance. The easily adjustable dual throats balance the pressure drop through the air flow system at the start-up or after system changes are made. The textile industry is plagued by air pollution problems which must be resolved. Each unit has a self-contained wash liquid reservoir and recirculating pump. This design feature eliminates the need for ductwork dampers and blast gates that are prone to particulate build-up and require periodic maintenance. A Wet Scrubber operates by introducing the dirty gas stream with a scrubbing liquid – typically water. Our experienced design team is focused on developing a solution which will fit your application and reach or exceed your emission goals. Type of Technology: Removal of air pollutants by inertial and diffusional interception. POLLUTION. The collection efficiency of the Ducon Oriclone Venturi Scrubber is a function of the pressure drop across the throat which, in turn, is a function of the quantity of submicron particulate matter suspended in the gas stream. Monroe Environmental offers several venturi design configurations: Monroe Venturi Air Scrubbers are currently operating continuously at high efficiency in many types of industrial installations throughout the United States, Mexico, and Canada. Although the Ducon Oriclone Venturi Scrubber Type VVO is included as a standard item of equipment in our line of gas scrubbers, it resists standardization and requires more of the "custom-designed” approach. A Monroe Dual Throat Venturi Scrubber was selected because of its ability to handle the sticky, water soluble particulate. Industrial scrubbers are pollution control devices that use liquid to wash unwanted pollutants from a gas stream, or that inject a dry reagent or slurry into a dirty exhaust stream to "wash out" acid gases. Since that time, Monroe Venturi Air Scrubbers have been successfully used for countless industrial and municipal applications. JET THROAT™ Venturi scrubber is designed to effectively use the energy from the inlet gas stream to atomize the liquid being used to scrub the gas stream. These scrubbers are designed for maximum efficiency and are ruggedly constructed for long service life with minimum maintenance. My Oil Water Separator (or CPI Separator) is Constantly Clogging! This feature also permits adjustment of pressure drop to upgrade collection efficiency to meet increased process or code requirements. Down stream particle removal happens at the diverging section as the gas is forced to slow down. In spite of taking less space and less money, the gas absorption and particulate removal are better with Venturis … Phone: 281-942-6700 Moisture eliminators also are constructed of materials suitable for the intended application, including polyethylene or stainless steel. Emissions versus pressure drop for venturi scrubbers serving coal driers (Engineering Science, 1979) Only the data shown in Figure 8-3 appear to have a correlation with a minimum amount of variability.

The Monroe Dual Throat Venturi Air Scrubber is a completely self contained unit that needs only to be connected to normal plant electrical, water, and air systems. Because of this, it’s critical for companies to know that one of the most effective tools against rising carbon emissions and the acidic chemicals being released into the atmosphere has been the use of wet scrubbers. A Venturi Scrubber can be engineered to collect both particulate and gas pollutants. For applications requiring the maintenance of a predetermined pressure drop level for varying inlet volumes, the Type VVO Scrubber can be provided with an adjustable throat mechanism. There is no apparent correlation in these data. Monroe Dual Throat Venturi Air Scrubbers are constructed of mild steel for most applications. We also transformed the original venturi … The 3 sections of a Ducon Venturi scrubber are converging, throat, and diverging sections. The droplets entrain and capture dust particles through agglomeration, adherence, or encapsulation. Atlanta: Anderson Company. must be based on the specific operating conditions. After passing through the turbulent dual throat wash zone, the air impinges on the liquid surface, changes direction and then continues through deflectors and into a large, double row moisture eliminator section. Packed towers, FGD, and other scrubber technology are more efficient at removing gas pollutants.
