Explosion danger testing device for gas-phase reaction system and using method thereof

Abstract

The invention discloses an explosion danger testing device for a gas-phase reaction system and a using method thereof. The device comprises a gas-phase feeding system, a reaction kettle, a high-pressure ignition system and a dynamic pressure collection system, wherein the gas-phase feeding system is connected with the reaction kettle, and is used for feeding a raw gas to be tested into the reaction kettle; the high-pressure ignition system is arranged on the reaction kettle, and is used for igniting the reaction kettle; and the dynamic pressure collection system is arranged on the reaction kettle, and is used for dynamically testing pressure in the reaction kettle in real time. The device of the invention can observe and study gas-phase explosion dangers by forcible ignition, and collect real-time data to observe and study gas-phase oxygen content controllability under different conditions so as to test the explosion dangers in gas-phase reaction by gas-phase ignition experiments.

Description

Technical field [0001] The present invention relates to the technical field of petrochemical industry, in particular to a gas-phase reaction system explosion hazard test device and a use method thereof. Background technique [0002] In the petrochemical industry, there is a type of reaction in which gas-phase organics react with each other to produce target products. The gas-phase oxidant can be air, oxygen-enriched gas, oxygen, etc. This type of reaction generally has the following safety problems: 1. When the gas velocity is too fast , May explode; under the condition of electrostatic ignition, explosion may occur and energy transmission may occur; 2. Due to improper control of the reaction conditions, the reaction does not proceed as planned, the oxidant enters the gas phase, and the unreacted oxidant completely enters the gas phase and the organic matter in the gas phase is mixed. There is a risk of gas phase explosion. [0003] At present, researchers mainly conduct research ...

AI Technical Summary

Problems solved by technology

[0002] In the petrochemical industry, there is a type of reaction in which gas-phase organic substances react with each other to form target products. The gas-phase oxidant can be air, oxygen-enriched gas, oxygen, etc. This type of reaction generally has the following safety problems: 1. When the gas velocity is too fast , an explosion may occur; under the condition of electrostatic ignition, an explosion may occur and form energy transmission; 2. Due to improper control of the reaction conditions, the reaction does not proceed as scheduled, the oxidant enters the gas phase, and the oxidant that has not completely reacted into the gas phase mixes with the organic matter in the gas phase. There is a risk of gas phase explosion

[0003] At present, researchers mainly study the optimal process conditions and mechanism of the reaction, lack of attention to safety, and a small amount of safety research is limited to the test of the explosion limit and the provision of critical oxygen content.
