The invention provides an LNG vaporizing emptying recycling and air supplementing pressurizing integrated device. The device comprises a heat exchanger (20), a one-way valve (12), an electromagnetic valve (13), an HC sensor (14), a dual-purpose gas storage tank (15), a pressure sensor (16), an emptying valve (17), a low-pressure filter (18), a pressure stabilizer (19), a low-pressure electromagnetic valve (21), an electric control pressure regulator (22), a one-way valve (26) and an electromagnetic valve (31). According to the device and the method, the problem of pressurization delay of an exhaust gas turbocharger is solved, and the surge of a gas compressor is avoided; the energy of turbocharging of an engine is fully utilized, and on the basis, an inflating pressurizing device is added,so that the hysteresis of the turbocharger is remarkably improved, and the power performance of a whole vehicle is obviously improved. 本发明提出的一种LNG汽化放空回收利用及补气增压一体化装置，包括：换热器(20)、单向阀(12)、电磁阀(13)、HC传感器(14)、两用储气罐(15)、压力传感器(16)、放空
