Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of carbon dioxide transport tank cars, and specifically is a carbon dioxide transport tank car. BACKGROUND

[0002] In the various departments of national economy, carbon dioxide has a very wide range of uses. Carbon dioxide products are mainly extracted and recovered from synthetic ammonia hydrogen production process gas, fermentation gas, lime kiln gas, acid neutralization gas, ethylene oxidation byproduct gas and flue gas, and the purity of commercial products is not less than 99% (volume). Carbon dioxide can be injected into beverages to increase pressure, resulting in bubbles in the beverage, enhancing the taste when drinking, such as soda and beer.

[0003] CO2 is widely used in various fields, and each field is relatively independent. Liquid needs to be transported to the required location by a transport vehicle. The transport distance is long, and the liquid carbon dioxide is a low-temperature liquid at -25°C. The low-temperature liquid needs to be fully insulated to ensure that the vehicle is as light as possible, the insulation effect is as good as possible, and the evaporation loss is as little as possible, while still being able to transport a long distance.

[0004] There are many feasible solutions for carbon dioxide transport vehicles at home and abroad, and some have been industrialized. For example, polyurethane foaming transport vehicles and high-pressure bottle group transport. Among them, polyurethane foaming transport vehicles have great advantages in manufacturing because their insulation can be achieved by polyurethane foaming alone. However, their insulation effect is much lower than that of vacuum insulation. The thickness of the foam is large, and sufficient length is required for transportation, which increases the axle of the vehicle frame and the weight of the entire vehicle. High-pressure bottle group transport considers that carbon dioxide is in a liquid state at high pressure and normal temperature. High-pressure steel bottle groups can be used without insulation at normal temperature. However, the pressure is high, and small volume is required, which occupies a lot of space and costs a lot.
