Abstract
The invention relates to a device for introduction of gases into reaction vessels containing liquids, especially vessels undergoing thermal stress, in particular filter housings for metal melts, using a gas-permeable body of heat-resistant material, fitting into a metal sleeve anchored in the wall of the reaction vessel. The wall of the reaction vessel consists of three different layers, namely a rigid inner layer of heat-resistant material, a loose intermediate layer of bulk material, and a casing of metal. The metal sleeve extends from the outside into the loose intermediate layer, the rigid inner layer and the gas-permeable inlet body are directly adjacent to one another, and the boundary surface of the gas-permeable inlet body has a permanently applied, thoroughly gas-tight cover of ceramic material.
