Design of neutralization tank
Abstract：The design is based on the design plan requirements and GB150 “Steek Pressure Vessels” and other provisions of the relevant standards. I designed a neutralization tank which is a mixing reaction kettle. Combing with the nature of the materials within the reactor operating conditions I did the design of the overall structure and selection of parts, the design and calculation of structure, the check of strength, etc. Jacketed reaction vessel with stirring, for the mixing efficiency, good sealing performance, the design of innovative used a propeller agitator, a baffle that can be formed in two circular flow, and a packing seal that meets the design requirements and is economical. This design is considering the process requirement, and considering the mixing efficiency and cost saving.It is convenient for factory to manufacture and operate.
Key Words: hydrolysis tank; stirring; jacketed reactor; jacket; seal
