ABSTRACT
Heat exchangers in many areas have awide range of applications, is a lot of industrial production process essential equipment, in today's energy shortage era, the heat exchanger for the mitigation of theworld energy crisis plays avery important role, its improvement And development has been an important research project forvarious countries and research institutions.
The design of the heat exchanger type of continuous mixing tank heat exchanger, through access to heat exchanger and other relevant information and previous experience on the heat exchanger design summary of the role of the heat exchanger and theworking principle of a certain understanding, And then according to the design requirements of the heat exchanger finishing the design priorities and order. And then according to the design requirements, such as the temperature of the medium, the pressure range of the equipment, aswell as the heat transfer area, the design of the heat exchanger for avariety of parameters, aswell as the choice of materials to complete the heat exchanger structure of the general design, Parts of the design, aswell as the installation steps and equipment of the anti-corrosion facilities. And according to the calculated data to draw the heat exchanger assembly drawings and parts drawings.
In the design,we must follow the correct design steps and methods to design, and the design ofvarious parameters to meet the national standards and regulations, strict implementation requirements, in order to meet the design requirements and can be safe for heat transferwork F30 Continuous stirring tank type heat exchanger.
