The double – layer insulation storage tank is defined in contrast to single – layer storage tanks and three – layer heating and insulation storage tanks. Simply put, it is a storage tank equipped with an insulation medium and an insulation layer, featuring functions of heat preservation and cold preservation. The purpose of a double – layer insulation storage tank is to prevent the short – term temperature drop of materials, maintain a constant temperature, and reduce heat loss. Generally, it can only maintain the temperature for a certain period, rather than keeping it constant for a long time. For example, in a process where there is a heating tank, an insulation tank is set up to store some hot materials for the connection between work shifts to improve efficiency. Common insulation storage tanks in processes include hot water tanks, cold water tanks, and insulation medicinal liquid storage tanks. If a double – layer insulation tank is equipped with an electric heating device (i.e., an additional heating layer), it will have both heating and insulation functions, enabling long – term temperature constancy and more powerful functionality.
Common types are vertical or horizontal storage tanks. They can be fully insulated (i.e., overall insulation) or partially insulated (i.e., only partial insulation). Compared with single – layer storage tanks, insulation storage tanks have a slightly more complex structure. They can preserve cold and heat, and prevent heat loss, making them a very environmentally friendly type of storage tank.
