Reactors and distillation kettles (including distillation kettles) are one of the most commonly used equipment in chemical industry. They are also equipments with high risk and are prone to leakage and fire and explosion accidents. Reactor refers to batch reactor with stirring device. Chemical reactions can be carried out under open, closed atmospheric, pressurized or negative pressures according to different pressure requirements. The distillation kettle is a device for separating homogeneous liquid mixtures.
The unreasonable design of reaction kettle and distillation kettle, discontinuous structure of equipment and improper welding seam arrangement may cause stress concentration; improper selection of materials, inadequate welding quality in the manufacture of containers, and improper heat treatment may reduce the toughness of materials; the corrosion of corrosive media on the shell of containers, the reduction of strength or the absence of safety accessories, etc., may make the containers in place. Explosion occurred during use.
