Abstract

The invention discloses a filling station cold energy utilization device. The filling station cold energy utilization device is characterized in that the utilization device comprises three low-temperature liquid storage tanks, a low-temperature filling trailer pump, a heat exchanger, a cold box, a low-temperature bottle, a vaporizer and a gas bottle group. The heat exchanger is arranged, cold energy charged in a normal-temperature steel bottle is collected through the heat exchanger, and cold energy is saved; and the cold energy charged in the normal-temperature steel bottle is used for condensing waste gas charged in the low-temperature bottle by utilizing the heat exchanger, so that the waste gas is prevented from being discharged and enters the low-temperature storage tanks to be storedafter being condensed, the waste gas is repeatedly used during subsequent charging, waste is turned into wealth, and the device is more environment-friendly.

Description

【Technical field】 [0001] The invention relates to the field of energy, in particular to a cold energy utilization device for a filling station. 【Background technique】 [0002] At present, the filling of industrial gases in the traditional market is divided into filling of normal temperature steel cylinders and low temperature steel cylinders. [0003] The filling of the normal temperature steel cylinder is that the low temperature storage tank is connected to the bottle filling pump and then directly vaporized and loaded into the normal temperature gas cylinder after being pressurized. During the filling process, the cooling capacity of the cryogenic liquid is directly transferred from the vaporizer to the surrounding air, which is equivalent to the direct waste of cooling capacity; [0004] Cryogenic steel cylinders are directly connected to cryogenic storage tanks for self-flow filling. During the filling process, due to the heat transfer of the low-temperature steel cyl...
