摘要: Disclosed herein is an energy efficient vertical cryogenic tank, which comprises a tank body with a vacuum insulation interlayer, wherein the tank body comprises a transmission means including an air return pipe and a liquid outlet pipe, and positioning means including supporting legs provided at the bottom of the tank body, and a built-in saturation adjustment mechanism formed by a heat exchanger connected to an let of the air return pipe and a return air dispersing device. By using a saturation adjustment mechanism at the inlet of the air return pipe, the cryogenic storage tank can not only fully leverage the gasification gas produced at the pump, but also achieve the saturation function of the LNG in the tank, with such benefits as reduced energy loss, simplified tank interface settings, improved efficiency of saturation adjustment, and avoided pump cavitation.

摘要: Disclosed herein is a tank-pump integrated structure for an LNG filling station, which comprises a tank body having heat insulation layer space, a siphon package at the bottom of the tank body and a pump sump arranged in the siphon package. Moreover, a first heat insulation pipeline in the siphon package is connected to an LNG inlet on the pump sump, and a gas return port of the pump sump is coupled with the tank body by means of a second heat insulation pipeline. An on-off valve is arranged on the first heat insulation pipeline between the tank body and the pump sump, a shut-off valve is additionally arranged on the second heat insulation pipeline between the gas return inlet and the tank body, and heat insulation devices are provided external to the on-off valve and the shut-off valve respectively. The integrated structure can reduce investment costs, shorten the construction period, and facilitate maintenance of the submersible pump via the valves.
