DEVICE AND METHOD FOR VAPORIZING LNG

摘要

A device for vaporizing LNG, comprising a seawater lead-in passage (13) formed in a device body (11) and leading seawater (12) therein, a heat exchange tube (14) installed in the seawater lead-in passage (13) and exchanging heat between the seawater (12) and the LNG, a bubbling device (16) disposed near the seawater inlet (13a) of the seawater lead-in passage (13) and supplying air (15) in the seawater, an air supply device (17) continuously supplying the air (15) from the outside to the bubbling device (16), and an outlet (18) communicating with the seawater lead-in passage to discharge the bubbling air (15) produced from the bubbling device (16) to the outside of the device body (11). The seawater (12) is forcibly led from the seawater inlet (13a) into the seawater lead-in passage (13) by the bubbling air (15) produced from the bubbling device (16), and the LNG supplied into the heat exchange tube (14) is vaporized to transform it to NG.
