Venturi Air Scrubber System ENV 010
Sci-tech Venturi Air Scrubber System Model ENV 010 s used to demonstrate dust pollution control and the effect of liquid -to-gas ratio (L/G) on separation efficiency. The system comprises of a venturi tube, separation chamber, dust feeding system, water recirculation system and a variable speed air blower.
The venturi tube is made of transparent and rigid plexi-glass for the observation of flow. A differential pressure transducer is used to measure pressure drop across the venturi. The cylindrical separation chamber is also made of transparent, rigid plexiglass with a diameter of 500 mm and height of 1.6 meter. At the side bottom of the separation chamber is a circular inlet which is connected to the outlet of the venturi. The chamber also houses a mist eliminator at the top which prevents water droplets from escaping the chamber. A collecting plastic tank is provided to collect the mixture of dust and water at the bottom of the separating chamber. The water recirculation system comprises of a water tank, pump, flow meter, pressure gauge and pressure regulator. The stainless steel water tank is located below the separation chamber and supplies water to the pump. A filter is attached to the pump inlet to prevent dust and debris from damaging the pump. The air blower is used to draw air at a maximum rate of 300 m3/hour through the separation chamber. The inlet air velocity can be adjusted by varying the air blower speed. The dust feeding system is used to simulate pollution in the air stream before entering the separation chamber. The system’s main frame is made of welded mild steel. The frame is epoxy-coated for aesthetics, durability and heat and corrosion resistance. A control panel is mounted on the steel frame as well to house all the electrical and electronic components.
