The invention relates to a device for mixing gases and liquids which has an intense mixing effect and is very easy to clean. The device comprises a housing with feed pipes for gas and liquid, into which an injector nozzle is inserted and a mixing nozzle is screwed.

Device for mixing gases and liquids

In an apparatus for the gasification of a biomass in an aqueous medium in the presence of organic substances degradable by the biomass, comprising a gasification tank, and a clearing chamber for the gasified water-containing biomass provided concentrically around the gasification tank, the gasification tank communicating with the clearing chamber through an inlet in the latter, the improvement wherein A. the gasification tank is from about 10 to 32 meters high, has a height/diameter ratio between approximately 40 and 0.2, is provided adjacent its floor with gas inlet points, and is connected via inlet pipes to at least one gas removal and flocculation cyclone; B. the same liquid level in all the clearing chambers is maintained by means of an overflow channel at about 0.1 to 2 meters below the liquid level of the gasification tank; and C. a sludge removal pipe connects each clearing chamber with a collector pipe. Advantageously the clearing chamber is funnel shaped.
