Abstract (en)
[origin: EP4230922A1] The present invention relates to an intake-type smoke removal system. The intake-type smoke removal system discharges gas flowing into a smoke removal zone to the outside of the smoke removal zone and includes a vacuum-generating multistage Venturi configured to allow water provided from the outside to pass therethrough, the vacuum-generating multistage Venturi being configured to generate negative pressure based on the Venturi effect while the water passes therethrough to suck the gas in the smoke removal zone, mix the sucked gas with the water, and discharge the gas mixed with the water.
