Low-temperature oxygenation compartment system for fresh aquatic product LNG transport vehicle

Abstract

The invention relates to a low-temperature oxygenation compartment system for a fresh aquatic product LNG transport vehicle. The compartment system comprises a compartment, an oxygenation system and an LNG cold energy utilization system. The oxygenation system directly or indirectly obtains refrigerating capacity from the LNG cold energy utilization system and cools oxygenation air, and the cooled oxygenation air is guided into water for carrying fresh aquatic products. The compartment system has the advantages that the refrigerating capacity of LNG is fully utilized for cooling the oxygenation air, so that the temperature of the oxygenation air is lowered to required temperature; furthermore, after the oxygenation air is blown into the water, no heat is transferred into the water, and water temperature can further be lowered and can be kept at 8-12 DEG C through controlling; in this way, because the water temperature does not need to be kept by supplementing ices in the transporting process, the usage amount of the ices can be greatly reduced, and the purchasing cost of the ices is saved; besides, due to the fact that the ices do not need to be carried in the transporting process, the transporting weight of the vehicle is reduced, and the transporting cost is greatly lowered.

Description

technical field [0001] The invention relates to a low-temperature oxygen-increasing compartment system of an LNG transport vehicle for fresh and live aquatic products. Background technique [0002] LNG fresh aquatic products refrigerated transport vehicle is a vehicle that uses liquefied natural gas as fuel. During the vaporization process of liquefied natural gas, a large amount of cold energy will be generated. By recycling the cold energy, the temperature of the refrigerator box can be reduced to the set value. temperature. [0003] At present, the oxygen supply system of the refrigerated transport vehicle for fresh and live aquatic products adopts the oxygen supply fan air supply system and the liquid oxygen oxygen supply system. Now, the air supply system of oxygen-increasing fan is widely used. The air will increase the pressure through the oxygen-increasing fan, and there will be a certain temperature rise. Bringing it in will increase the water temperature in the b...

Problems solved by technology

Now, the air supply system of oxygen-increasing fan is widely used. The air will increase the pressure through the oxygen-increasing fan, and there will be a certain temperature rise. Bringing it in will increase the water temperature in the bucket, and the suitable temperature for general fresh aquatic products is 8-12°C, so it is necessary to manually add ice to ensure the water temperature, which will greatly increase the consumption of ice

This not only increases the cost of purchasing ice, but also increases the loading weight of the vehicle due to ice, which greatly increases the transportation cost
