CATALYTIC REACTOR Russian patent published in 1998 - IPC

FIELD: equipment for cleaning of process and ventilation gases from impurities of organic substances; may be used in chemical, machine-building and other industries. SUBSTANCE: catalytic apparatus has two reactors each including regenerative heat exchanger and a layer of catalyst installed in one body, chamber connecting the reactor with heating elements located in chamber between catalyst layers, air-supplying conduits, valves for changing the direction of flow of gases. Reactors are provided in their lower part with valves communicating them with atmosphere. Installed in body in a spaced relation to each other are the reactors to form together with body the vertical channel connecting the chamber with valve for changing the direction of flow of gases. Heating elements are placed into plate-type heat-exchangers. Regenerative heat exchangers are separated into sections installed in a spaced relation to one another. Formed in channel middle part by vertical partitions and bottom plate is channel for fuel introduction in which plate-type heat exchangers are installed at the height of catalyst layer. Valve for changing direction of flow of gases has end hollow communicating with middle pocket of rotary switch and vertical channel of the apparatus. EFFECT: reduced power consumption and higher degree of gas cleaning. 3 cl, 7 dwg
