D G Set Venturi Scrubber

A venturi scrubber accelerates the waste gas stream to atomize the scrubbing liquid and to improve gas-liquid contact. In a venturi scrubber, a “throat” section is built into the duct that forces the gas stream to accelerate as the duct narrows and then expands.Venturi scrubbers can be used to remove small particles (< 1 µm) from a gas stream. However, they can also be used for larger particles, though energy use is relatively high in such cases. Even at very high pressure drops, some types of dust cannot be separated.Venturi are used to measure the speed of a fluid, by measuring the pressure changes from one point to another along the venture. A venturi can also be used to inject a liquid or a gas into another liquid.
