摘要：NOVELTY - The utility model claims a shell body is set in the fixed bed reactor is a cylindrical cavity, the cylindrical cavity along the upper and lower tube plate and shell body, the upper end enclosure comprises a box, a cylindrical cavity and a lower end enclosure pipe box, the pipe box end enclosure, lower end enclosure pipe box are respectively connected with the upper tube plate and the lower tube plate is welded, the inner ring cavity of the reactor to form a shell body in the cylindrical cavity of a reaction tube, the reaction tube is connected with the upper tube plate and the lower tube plate; This utility model is a loop connected to nozzle and the cavity, a loop connection mouth and the lower cavity is provided with the heat uniformly to enter into upper and lower ring cavity so as to avoid the fluid distributed in the ring cavity of the non-uniformity, at the same time, avoids the upper and lower cavity wall discomfort caused by heat is not uniformly enter into the problem of the reactor shell, the cylindrical cavity is set with reaction tube, which avoids forming heat channelling in the centre of the shell, the centre of the shell to prevent the temperature of the part is not uniform.
