Venturi Scrubber

Metso's Outotec Venturi Scrubber is a high-pressure scrubber that cleans electric furnace off-gas and effectively pressurizes the CO gas line.

Handle explosive gases in the safest possible manner. The efficient and secure operating principle is to both cool and clean the gas and to quench sparks from the furnace.

In addition to minimizing air pollution, Metso's Outotec Venturi Scrubbers improve electric furnace operation and increase equipment availability. The scrubber is very simple to operate as it has no moving mechanical parts.

Reduces emissions to surrounding atmosphere
Operates reliably for low maintenance requirements and costs
Effectively removes slurry
Operates consistently even with variations in gas flow
Enables safe CO gas handling due to overpressure operation

Metso's Outotec Venturi scrubber is an easy-to-operate, high-pressure scrubber for effective and safe cleaning of harmful and explosive process gases. The scrubber aspirates furnace off-gases and produces overpressure in the gas line. This overpressure prevents surrounding air from entering the line, enabling safer handling of CO gas. It both cools and cleans the gas, quenching sparks from the furnace to eliminate the risk of explosion.

Our Venturi scrubbers have a proven track record in the cleaning of off-gases from closed smelting furnaces. They are designed to operate in tandem in order to guarantee the maximum possible gas-cleaning efficiency, uniform ventilation of off-gas from the furnace, and to minimize equipment footprint. Combining Metso's Outotec Venturi scrubber with the Metso CO gas filter ensures exceptional cleaning of electric furnace off-gases, with collection efficiencies close to 100%.

Metso's Outotec Venturi scrubber combines the following functions into a single unit:
