Abstract

The invention relates to the technical field of low-temperature storage tanks, in particular to a low-temperature storage tank. The low-temperature storage tank comprises a tank body used for containing low-temperature liquid and a liquid outlet device communicating with the tank body and used for conveying the low-temperature liquid outwards; the liquid outlet device comprises a liquid outlet pipe and a valve; the liquid outlet pipe comprises an initial pipe section inserted into a liquid phase space of the tank body, a buffer pipe section used for buffering low-temperature liquid and a tailend pipe section penetrating out of the tank body; the two ends of the buffer pipe section are connected with the initial pipe section and the tail end pipe section correspondingly; the buffer pipe section is fixed in the tank body and at least partially located in the gas phase space of the tank body; and the valve is arranged on the tail end pipe section and used for controlling the opening andclosing of the liquid outlet pipe. The maintenance time of the low-temperature storage tank in the standing process is greatly prolonged; frequent tripping of the safety valve is avoided, the discharge amount of BOG gas is greatly reduced, economic loss and potential safety hazards are reduced, and therefore economic efficiency and sociality are guaranteed.

Description

technical field [0001] The invention relates to the technical field of low-temperature storage tanks, in particular to a low-temperature storage tank. Background technique [0002] At present, during the filling process of the vacuum insulated cryogenic storage tank, the BOG gas and the tank body in the tank can be cooled through the top spray pipe. During the use of the vacuum insulated cryogenic storage tank, the excess BOG gas can be discharged out of the tank through the regulating valve and the saving pipeline, so as to realize the depressurization of the vacuum insulated cryogenic storage tank. However, during the use of vacuum insulated cryogenic storage tanks, no cooling and cooling measures have been taken to reduce the impact of external heat on the vacuum insulated cryogenic storage tanks, resulting in the continuous generation of a large amount of BOG gas in the vacuum insulated cryogenic storage tanks , so it is inevitable that the pressure of the vacuum insula...
