Automatic pressure relief and explosion-proof type reaction kettle pressure relief system

Abstract

The invention discloses an automatic pressure relief and explosion-proof type reaction kettle pressure relief system, and relates to the field of pressure relief of reaction kettles. The reaction kettle comprises a kettle body, a pressure relief pipe is installed on one side of the top of the kettle body, a support is installed on the outer side of the pressure relief pipe, a limiting sleeve is fixed to the top of the bottom end of the support, a sliding groove is formed in the inner side of the limiting sleeve, and a pressure sensor is installed on the sliding groove. When the pressure sensor is in an extruded state for a long time, the pressure relief pipe compresses the spring to the limit all the time and extrudes the pressure sensor at the same time, resistance changes are generated after a metal resistance strain gauge on the pressure sensor is subjected to mechanical shape, and therefore the resistance changes are converted into digital signals to be transmitted to an operation panel; if yes, the operation panel automatically turns on the alarm lamp to give an alarm to remind workers, the workers open the active pressure relief pipe, the pressure in the reaction kettle is kept stable, the reaction kettle is prevented from being in a high-pressure state for a long time, and safety is improved.

Description

technical field [0001] The invention relates to the field of reactor pressure relief, in particular to an automatic pressure relief and explosion-proof reactor pressure relief system. Background technique [0002] The broad understanding of the reaction kettle is a stainless steel container with physical or chemical reactions. The structural design and parameter configuration of the container are carried out according to different process conditions. The design conditions, process, inspection, manufacturing, and acceptance must be based on relevant technical standards to achieve process requirements. Unique heating, evaporation, cooling and low-speed high-speed mixing reaction functions. [0003] According to the search, the Chinese patent No. 201922207097.4 discloses a reactor for chemical production with automatic pressure relief function, which reduces the pressure of the reactor by setting an automatic pressure relief device, but there are still problems in this patent. ...

AI Technical Summary

Problems solved by technology

[0004] Based on this, the purpose of the present invention is to provide an automatic pressure relief, explosion-proof reactor pressure relief system to solve the problem that the pressure relief is not stable enough and when the pressure increase rate in the reactor is greater than the pressure relief rate, excessive pressure will still occur. Situations, high-risk technical problems
