Design and Optimization of Neutralization reacter
Abstract: The reaction tank is an important equipment of the chemical industry, which consists of tank body, jacket, stirrer, transmission device, shaft seal device, bearing and so on, set the manhole can carry out equipment maintenance, the tank medium is acidic Body, jacket medium for the hot oil, the tank operating pressure is 0.5MPa, the operating temperature of 100 ℃. The jacket operating pressure is 1.1 MPa and the operating temperature is 180 ° C. The equipment volume is designed to be 8m3. This paper describes the design process of the above components. The inner diameter, length and thickness of the cylinder and cylinder head and jacket and jacket are calculated and checked for strength. , To ensure the safety of the design of the main equipment.
