CATALYTIC APPARATUS Russian patent published in 2007 - IPC B01J8/02 

FIELD: chemical industry; other industries; catalytic devices used for purification of the technological and ventilation gases from the vapors of the organic substances.

SUBSTANCE: the invention is pertaining to the catalytic devices used for purification of the technological and ventilation gases from the vapors of the organic substances and may be used in many branches of industry. The catalytic apparatus contains: the body made in the form of the spiral two-channel heat exchanger-recuperator, which spirals are fulfilled from the semi-cylindrical shells, the gases inlet and outlet fitting pipes, the catalytic and the electrically heated sections arranged in the inside concavity of the heat exchanger-recuperator. The spirals of the heat exchanger-recuperator contain the plane sections connecting the semi-cylindrical shells. At that the spiral of the inlet channel is connected to the electrically heating section, and the spiral of the outlet channel is connected to the catalytic section divided into parts. On the coils of the spiral channels of the heat exchanger-recuperator there are the mounted unions used for feeding the vapors of the organic substances - the production waste products, for feeding of the washing liquor, for feeding of the compressed air to cool the apparatus, for sampling the probes. The invention ensures protection of the catalytical apparatus against pollution, reduction of the power inputs, the improved conditions of the maintenance of the spirals of the heat exchanger-recuperator.

EFFECT: the invention ensures protection of the catalytical apparatus against pollution, reduction of the power inputs, the improved conditions of the maintenance of the spirals of the heat exchanger-recuperator.
