ABSTRACT:
A method and apparatus for the treatment of a waste gas containing dust and chemical contaminants are disclosed. The apparatus includes a combination of a cooling/dust-eliminating chamber and a chemical treatment chamber in a single container. The first mentioned chamber is provided with sprayers for the cooling liquid, a perpendicular bulkhead or pipes, a collecting plate for the cooling liquid and gas-dispersing pipes in a special configuration, so that the dust-liquid separation can be efficiently effected without badly affecting the chemical treatment of the gas. Thus, the apparatus can be minimized in size as a whole and made economically attractive.
