AI Technical Summary

Technical Problem

In the existing reactor for the hydration reaction of 1,2-propylene glycol, the pressure relief device is prone to corrosion and damage, and the multi-layer sealing structure restricts the exhaust channel, making it difficult to reduce the pressure inside the reactor quickly, which affects the reaction efficiency and poses a safety hazard.

Method used

A pressure buffer and safety release device for a reactor is designed. Through the coordinated operation of the connecting components and the buffer tank, the movement of the block is controlled by the elastic components and the limiting components to form multiple exhaust gaps, so as to quickly discharge excess gas and avoid excessive pressure inside the reactor.

Benefits of technology

This allows for the rapid discharge of gas from the reactor, ensuring the safe operation of the reaction apparatus, providing a stable reaction environment, and preventing equipment damage and safety accidents.

Abstract

The utility model discloses a kind of reaction kettle pressure buffering and safety release device, it is related to reaction kettle technical field, including reaction kettle, top is equipped with connecting assembly;The beneficial effect of the utility model is that: through the collaborative cooperation of connecting assembly and buffer tank can be when the gas pressure in reaction kettle rises to abnormal state, transfer the expanded gas to buffer tank, and extrude stopper to generate first exhaust gap and second exhaust gap, excess gas is discharged quickly, avoid the pressure in reaction kettle to exceed equipment tolerance value, guarantee reaction device safe operation;In addition, first exhaust gap and second exhaust gap can continue to increase with stopper descending, until annular groove moves to with lower baffle ring coplanar, so that the discharge capacity of gas and the gas pressure value in reaction kettle are positively correlated, accelerate the gas discharge efficiency under high pressure state, to provide stable environment for hydration reaction.
