Fixed bed fluorination reactor

Abstract

The invention relates to a fluoridation reactor of a fixed bed. The technical scheme includes that a closed reaction container comprises a lower header, a lower tube plate, a barrel, an upper tube plate and an upper header. A manhole I, a pressure gauge port I and a discharge outlet are arranged on the lower header; an outer barrel I and an outer barrel II are arranged at two ends of the barrel, perforated plates are arranged between the outer barrel I and the barrel and between the outer barrel II and the barrel, and a plurality of baffles, a plurality of distance tubes and a plurality of heat exchange tubes are arranged in the barrel; one end of each distance tube is fixed to the lower tube plate, and the other end of each distance tube is fixed to the corresponding baffle; the heat exchange tubes penetrate through two ends of each baffle, then are respectively welded with the lower tube plate and the upper tube plate, and are communicated with the lower header and the upper header, and a catalyst supporting spring device is mounted at the bottom of the inside of each heat exchange tube; and a steam inlet is arranged on the upper tube plate, and a condensate outlet is arranged on the lower tube plate. A manhole II, a mixed gas inlet, a pressure gauge port II, a plurality of temperature measuring ports and a manhole III are arranged on the upper header. The fluoridation reactor is good in heat transfer effect and reliable in running.

Description

technical field [0001] The invention relates to a reactor for producing refrigerants, in particular to a reactor for producing green and environment-friendly fluorinated refrigerants that can reduce the greenhouse effect. Background technique [0002] Some existing reactors and heat exchangers are generally heated by steam and heat transfer oil, and the general temperature is about 250°C. The temperature range of the reaction process is not easy to control, the heat transfer effect is poor, and it is difficult to ensure sufficient reaction. It is difficult to guarantee the final quality of the refrigerant. Contents of the invention [0003] The purpose of the present invention is to provide a fixed bed fluorination reactor, tetrachlorethylene or trichlorethylene and hydrogen fluoride can fully react in the equipment after being heated by molten salt; the catalyst loss is reduced, and the effective coefficient of the catalyst is improved; The heat transfer methods of heat ...
