Tubular fixed bed reactor for methanethiol

The invention relates to a tubular fixed bed reactor for methanethiol. The reactor comprises an upper tube box, a shell pass cylinder body and a lower tube box from top to bottom, wherein the shell pass cylinder body is internally provided with an upper tube plate, reaction tubes and a lower tube plate, and two ends, i.e., an upper end and a lower end, of the reaction tube are respectively in sealing connection with the upper tube plate and the lower tube plate; a lower tube of the reaction tube is internally provided with a catalyst support spring. The reactor provided by the invention can conveniently be filled with a catalyst, when a single reaction tube leaks, the reaction tube can be directly blocked, the catalyst does not require to be completely dismantled, the equipment is convenient to maintain in a later period, and the maintenance cycle is shortened. 本发明涉及种甲硫醇列管式固定床反应器，自上而下包括上管箱、壳程筒体和下管箱，壳程筒体内设置有上管板、反应管和下管板，反应管上下两端分别与上管板和下管板密封连接；反应管下部管内设置有催化剂支撑弹簧。本发明的反应器能方便装填催化剂，当单只反应管出现泄漏时可直接封堵该反应管，不需全部拆除催化剂，便于后期设
