Low-temperature tank container

Abstract

The invention provides a low-temperature tank container. The low-temperature tank container comprises a frame and a tank body horizontally arranged in the frame. The tank body is used for storing low-temperature liquid. The low-temperature tank container further comprises a connecting pipe, a gasification heat exchange pipe and a discharge pipeline system; the connecting pipe penetrates through the tank body and extends into the tank body so as to communicate with the gas phase space of the tank body; the gasification heat exchange pipe is fixedly arranged on the tank body; the gasification heat exchange pipe extends in the axial direction of the tank body and does not exceed the outer side of the frame; an inlet and an outlet are formed in the two ends, in the axial direction, of the gasification heat exchange pipe correspondingly, and the inlet is connected and communicates with the end, exposed out of the tank body, of the connecting pipe; and the discharge pipeline system is connected and communicates with the outlet of the gasification heat exchange pipe. The gasification heat exchange pipe is located in the atmospheric environment, low-temperature media flowing through the interior of the pipe can participate in heat exchange with the outside atmosphere, then absorb heat and are gasified into gas, the gas is discharged through the discharge pipeline system, and the temperature of the gas is relatively high so that the risk of frost cracking cannot be generated to adjacent containers and ships.

Description

technical field [0001] The invention relates to the technical field of cryogenic containers, in particular to a cryogenic tank container. Background technique [0002] At present, the proportion of LNG (liquefied natural gas) in the energy structure of various countries is increasing, and the transportation mode of LNG is constantly being innovated. As a new LNG logistics and trade model, there have been many attempts in the industry to use LNG tank containers for containerized transportation. [0003] LNG tanks are transported as containers, especially in the case of sea transportation, there must be large-scale stacking and storage, but the low temperature characteristics of LNG (-162 ℃) determine that once LNG is ejected from the tank, it will cause damage to adjacent tanks. Great damage was done to tanks and hulls. LNG tanks generally use vacuum insulated tanks. When the vacuum of the tank is accidentally damaged, or the storage time of the tank exceeds its maintenance...

Problems solved by technology

But this greatly increases the storage distance of tank containers, which greatly reduces the storage capacity of tank containers per unit area, and the economy is very poor.
