Catalyst crushing and absorbing device of tubular reactor

Abstract

The invention discloses a catalyst crushing and absorbing device for a tubular reactor, which relates to the catalyst discharging and crushing device of a tubular reactor in the chemical industry and the petrochemical industry. The catalyst crushing and absorbing device is supported by a base (8), a base elbow (6) is arranged on and communicated with the base (8), the port of the base elbow (6) is provided with an absorption pipe head (7), and the base elbow (6) is connected with the absorption pipe head (7) in a sealing mode. A lengthened bar fixed cashing pipe (5) through which an electric crushing device can pass is arranged next to the port of the base elbow (6), the electric crushing device and the lengthening bar fixation cashing pipe (5) are in the sealing status, and the electric crushing device is fixed by a support bar (1). The catalyst crushing and absorbing device of a tubular reactor completely solves the crushing problem of a serious hardened catalyst, lowers difficulty of catalyst discharging, and shortens catalyst discharging time. The catalyst crushing and absorbing device of a tubular reactor is provided with a unique lengthening bar fixation cashing pipe.

Description

technical field [0001] The invention relates to the technical field of catalyst unloading for tubular reactors in the chemical industry and the petrochemical industry, in particular to a catalyst crushing device. Background technique [0002] Many chemical reactors are fabricated as shell and tube heat exchangers with many parallel, vertical tubes extending from a top tube sheet to a bottom tube sheet. During use, the tubes typically contain catalyst, and periodically the reactor must be shut down, the catalyst removed, the tubes cleaned, and fresh catalyst loaded. Difficulties are often encountered during the unloading process. When replacing the catalyst, the general method is to use a metal rod or a rod made of other materials to vibrate upwards from the lower opening of the reactor to make the catalyst inside the reactor tube fall down. All or some of the tubes in the reactor, due to thermal changes or composition changes during the operation, the catalyst in the tubes...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the problem of catalyst hardening during the unloading of the existing tubular reactor, the present invention designs a novel catalyst crushing and suction device for the tubular reactor, which can not only improve the unloading efficiency of the catalyst, speed up the unloading time, but also eliminate The problem of dust pollution when unloading the agent can completely solve the problem of severe hardening and breaking of the catalyst.
