CATALYTIC REACTOR FOR EXOTHERMIC PROCESSES RUNNING IN A GAS-SOLID PHASE WITH A SMALL DIFFERENCE OF TEMPERATURES

摘要

FIELD: chemical industry; catalytic reactors.;SUBSTANCE: the invention is pertaining to the field of chemical industry and may be used as a catalytic reactor for the exothermic processes running in a gas - solid phase with a small difference of temperatures. The body of the reactor is divided into the ceiling with the upper flange and the cylinder with the lower flange tightly joined with a partition, or the partition is tightly fused to a support ring of the body. A set of cooling pipes contains: an inlet pipe, horse-shoe mains (or the top and bottom horse-shoe mains), cooling pipes. The cooling pipes represent U-shaped pipes. A horse-shoe main links the inlet pipe and one end of a U-shaped cooling pipe, which is a descending cooling pipe. The other end of the U-shaped pipe with the overhead hole is an ascending cooling pipe, or the cooling pipe consists of a descending cooling pipe and an ascending cooling pipe. The overhead horse-shoe main links the inlet pipe and the descending cooling pipe, and the lower horse-shoe main links the descending cooling pipe and the ascending cooling pipe. The inlet pipe passes through a partition and is sealed by a demountable tightening element. The raw gases from the inlet for gases in the upper part of the body enter into the overhead chamber, pass through the inlet pipe and a horse-shoe main, then are distributed among the cooling pipes. Raw gases are moving top-down in the descending cooling pipes and take part in the heat exchange with the reaction gases placed outside the pipes. The raw gases reach the upper part of the ascending cooling pipes and leave them. In the layer of the catalyst placed outside of the pipes the gases are moving top-down and during the reaction a heat exchange with the raw gases take place. The reaction gases reach the bottom, pass through a perforated screen and leave the reactor through an outlet of the bottom. The given technical solution ensures high activity of the catalyst at a simple and reliable design of the reactor.;EFFECT: the invention ensures high activity of the catalyst and a simple and reliable design of the reactor.;6 cl, 6 dwg, 2 ex
