An automatic constant temperature and pressure device in a gas environment

Abstract

The invention discloses an automatic constant temperature and pressure device in a gas environment, which includes a high temperature acquisition structure, a constant pressure structure, and a product collection structure. The high temperature acquisition structure includes a reactor, a constant temperature control cabinet installed on the reactor, and a The reactor brackets at both ends of the reactor; the constant pressure structure includes: a constant pressure control cabinet, the first constant pressure fitting, and the second constant pressure fitting; the product collection structure includes: a condenser, a gas-liquid separation tank, and an exhaust gas treatment device. One end of the tank is connected to the second constant pressure fitting, and the other end is connected to the gas-liquid separation tank; one end of the gas-liquid separation tank is connected to the condenser, and the upper wall of the other end is connected to the tail gas treatment device; the tail gas treatment device is connected through a three-way pipe joint There are exhaust ports and gas collection ports. The invention realizes the constant temperature and constant pressure adjustment of the reaction system, and the reaction tail gas is discharged and collected after purification treatment, the reaction temperature and pressure are controlled stably, manpower and material resources are saved, the safety factor is high, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of constant temperature and constant pressure reaction equipment, in particular to an automatic constant temperature and constant pressure device in a gas environment. The device is suitable for automatic feeding and continuous online reaction in a high pressure environment, and is also suitable for the preparation reaction of batch continuous materials. Background technique [0002] At present, in the field of chemical reactions, the synthesis reactions of many chemical substances need to be reacted in tubular or tank reactors, and part of the reactions need to be reacted under the conditions of feeding a fixed pressure gas and maintaining a specific reaction temperature. However, along with the continuous progress of the reaction, part of the reaction will release gas to increase the pressure of the system, and the automatic control of the pressure cannot be realized. [0003] For example, in the production process ...

Problems solved by technology

[0004] Therefore, it is difficult to achieve automatic constant temperature and pressure control for existing chemical reactions in the presence of gaseous environments or atmospheres, resulting in uneven and stable temperature and pressure control, consuming manpower and material resources, low safety factor, and the yield and purity of reactants cannot be guaranteed. , which reduces the production efficiency and brings unnecessary losses to the production, and further improvement is urgently needed to meet the requirements of constant temperature and constant pressure gas reaction
