Abstract
The utility model discloses a reaction kettle. The reaction kettle comprises a kettle body and a safety valve, wherein the safety valve is communicated with the inner cavity of the kettle body through a safety valve pipeline; and a rupture disk is fixedly arranged on the safety valve pipe. The rupture disk, which is fixedly arranged on the safety valve pipeline of the reaction kettle, can function as a blind plate when the pressure in the reaction kettle fails to reach the takeoff pressure of the safety valve, so as to effectively avoid a leakage phenomenon; and the rupture disk ruptures firstly when the reaction kettle exceeds pressure in case of abnormal production, and the safety valve takes off and releases air into an absorption cell through a tail gas pipe, thus avoiding a safety accident in case that the reaction kettle exceeds the pressure. The reaction kettle, through the improvement of mounting the rupture disk on the safety valve pipeline, can effectively avoid a leakage problem of the safety valve, so as to guarantee safety production.
