Provided are a method and to a wet scrubber for removing particles from gas. The wet scrubber includes a second vertical cylindrical vessel having a second upper end for receiving an accelerated stream of liquid- and particles-laden gas from a vertically oriented venturi channel and a second lower end for feeding the accelerated stream of liquid- and particles-laden gas to a swirl generator. The second vertical cylindrical vessel and the swirl generator are arranged in a vertical cylindrical separation space of a first vertical cylindrical vessel. The swirl generator is arranged above the liquid tank.

Method and wet scrubber for removing particles from gases

A process for producing a solution of a gas in a liquid in which the gas is soluble, the solution having a predetermined concentration up to saturation. The gas and the liquid are brought together under controlled supply in a proportion corresponding to the predetermined concentration of the solution, and the gas and the liquid are caused to form a stream passing through a common conduit. The gas and the liquid in the stream are caused to intermix under the action of gravity, and the intermixing is repeated before the gas and the liquid have separated, so that the gas is substantially absorbed in the liquid, forming a gas-liquid solution of the predetermined concentration. The stream may be brought into turbulence for intensifying the intermixing of the gas and the liquid. An apparatus for performing the process includes a conduit including a continuous tubular coil formed with a plurality of upwardly and downwardly directed sections. Suitably, elements generating turbulence are disposed within the tubular coil, as is also a pressure-sustaining valve which maintains a predetermined overpressure in the conduit is provided. Suitably, the tubular coil is shaped as a horizontal helix.
