1. Collecting process design data: After material balance and heat balance calculation, it is known that the temperature, pressure, maximum use pressure, maximum use temperature, minimum use temperature, corrosiveness and toxicity of the medium will be stored in the stainless steel storage tank. Steam pressure, inflow and outflow, etc., these data are collected as the basic data of the design.
2. Selection of materials for stainless steel storage tanks: For chemical storage tanks, the corrosiveness of the medium is an important factor in considering the material of the storage tank. Corrosive materials can be selected from enamel containers and glass-lined containers depending on the working pressure and working temperature. The steel pressure vessels can be lined with rubber, lined with porcelain, and lined with polytetrafluoroethylene to improve the corrosion resistance of the container.
3. Determine the type of stainless steel storage tank: The choice of storage tank type includes horizontal or vertical and head type. According to the requirements of the process conditions, the container type selected from the national standard series containers is matched with the parameters of the process conditions (working pressure, working temperature, medium, volume).
4. Determine the total volume of material to be stored: the determination of the total volume of stored materials is as follows.
5. Determine the number of stainless steel storage tanks and the initial size: the total volume of material to be stored divided by the appropriate volume of the stainless steel storage tank is rounded up to the required number. Firstly, the appropriate volume of the tank is initially determined. The appropriate volume of the tank is determined according to the type of the tank, the nature of the stored material, the size of the site that can be provided, and the processing capacity of the equipment. After determining the appropriate volume of the tank, The value obtained by dividing the total volume of the material to be stored by the appropriate volume of the storage tank is the required number after the rounding. After the number of units is determined, it is adjusted back to adjust the initial suitable volume to obtain the real storage tank. Volume.
6. Select the standard model: According to the initially determined tank diameter, length and volume, working temperature, working pressure, corrosiveness of the medium, etc., try to select the specifications in the national standard series. If you can't find the matching specifications from the standard series, you should choose a similar specification, and make some adjustments to the size and nozzle to use as non-standard equipment, which can greatly save the design workload.
