liquid carbon dioxide cryogenic storage tank brief introduction

Carbon dioxide storage tank is the main container for storing carbon dioxide, and the carbon dioxide in the container is in the form of cryogenic liquid. In order to maintain the cryogenic state of carbon dioxide, it usually needs the assistance of refrigeration equipment. When the carbon dioxide stored in the pressure vessel needs to be vaporized, it needs the corresponding vaporizer, and the carbon dioxide can be delivered to the required after being decompressed In order to be convenient for use in the production workshop, sometimes carbon dioxide needs to be directly poured into the steel cylinder for standby.

Carbon dioxide cryogenic storage tank has a wide range of uses. This kind of container provides high-purity gas for hospitals, food factories, and steel mills. Compared with traditional steel cylinders, it has a higher safety and economy, and can effectively reduce the operating costs of enterprises. Therefore, the utilization rate of this carbon dioxide storage tank is also increasing in recent years.

As the market demand for carbon dioxide cryogenic storage tank is increasing year by year, more and more manufacturers produce this kind of pressure vessel, and have launched various products of performance and specification. The safety performance of carbon dioxide storage tank is often the most concerned by manufacturers in the production and design. Currently, better products usually adopt double safety system and use combined safety valve to achieve The purpose of ensuring safety is to ensure the normal operation of carbon dioxide storage tank even during safety verification, and not stop due to verification. In addition, the convenience of operation is also the key content of the manufacturer in design. The tank structure of carbon dioxide storage tank is generally in the form of double-layer container, that is to say, it has two layers of inner and outer containers. At the same time, the material of inner container and outer container is not the same. On the surface of carbon dioxide cryogenic storage tank, coating will be applied after a series of processes such as sandblasting. The inner and outer two layers of containers will be vacuumized directly, and the inner and outer two layers of containers of pressure vessel will be vacuumized directly. The most common filling material for thermal insulation is pearlescent sand. There are vertical and horizontal tanks, which can be selected according to the needs. The carbon dioxide in the tank is stored in a cryogenic form. In order to maintain the cryogenic, the tank storage tank will be equipped with corresponding refrigeration equipment. When the temperature exceeds the limit, the refrigerator will be opened to ensure that the carbon dioxide in the tank is below the specified temperature.
