A Venturi scrubber is a device used to remove pollutants from industrial exhaust gases. It works by forcing the gas through a narrow section, called the Venturi throat, which increases the gas's velocity. This high-speed flow creates a vacuum that draws in a scrubbing liquid, usually water, to capture and neutralize harmful particles and gases. The mixture of gas and liquid then flows into a larger section where the velocity decreases, allowing the liquid to settle and separate from the cleaned gas. This process effectively reduces emissions, making it an important technology for industries aiming to comply with environmental regulations.
