Description

Pressure reaction kettle for chemical production Technical Field The utility model relates to the technical field of reaction kettles, in particular to a pressure reaction kettle for chemical production. Background In the chemical production process, the pressure reaction kettle is one of common equipment, and certain pressure is required to be maintained in the pressure reaction kettle to ensure the normal operation of chemical reaction. However, excessive gas or pressure fluctuation may be generated in the reaction process, and if the pressure cannot be regulated timely and effectively, the pressure in the reaction kettle may be too high, so that safety accidents, such as explosion, are caused, and the life safety of production personnel and the normal operation of production equipment are seriously threatened. However, the existing pressure reaction kettle has defects in pressure relief and pressure regulation, and cannot well meet the safety and stability requirements of chemical production. Especially, the reaction kettle taking the rupture disk as a main pressure relief means, the rupture disk is a disposable device, the cost is too high, and the air flow generated during blasting can cause the shaking of the whole reaction kettle, thereby affecting the normal operation of the chemical reaction inside and causing larger safety accidents.
