Brief：Liquid carbon dioxide storage tank structure composed of inner and outer containers double container liner material used 16MnDR, outside the gall material is Q235B or 16MnR. Surface anti-corrosion coating using sand-blasting, blowing, spraying and other processes, while using a two-component fast curing liquid coating. Inner and outer containers perlite insulation sandwich filling and vacuum (divided into vertical and horizontal). In order to maintain low temperature conditions, the tank must be equipped with refrigerator, when the temperature rises, open chiller, the carbon dioxide storage tank temperature drops to the design temperature. In the storage tank is equipped with a pressure gauge, and in order to facilitate users, storage tank is also equipped with an automatic instruction level, Weighing stock.
