Embodiment 1
[0017] Such as figure 1 As shown, the LNG emergency gas supply device includes a gasification device, a first temperature gauge 3, a first pressure gauge 6, a second temperature gauge 7, a safety valve 8, and a pressure regulating group 9, which are sequentially connected in series by a gas transmission pipeline 4 , And the second pressure gauge 10. The gasification device is composed of one gasifier or a plurality of gasifiers 1 connected in parallel, and a ball valve 2 is installed on the gas inlet or gas outlet of the gasifier 1 . A ball valve 2 is installed between the first temperature gauge 3 and the first pressure gauge 6, and a heating device 5 is connected in parallel to the ball valve 2 between the first temperature gauge 3 and the first pressure gauge 6, and a heating device 5 is installed in the heating device 5 Natural gas burner 51. The gas pipeline 4 behind the second pressure gauge 10 is divided into a user pipe 41 for supplying gas to the user and a gas supp...
Embodiment 2
[0019] On the basis of Embodiment 1, the LNG emergency gas supply device can also include a vehicle frame, the vehicle frame has wheels, the gasification device, the first temperature gauge 3, the first pressure gauge 6, and the second temperature gauge 7 , safety valve 8, pressure regulating group 9, second pressure gauge 10, heating device 5, and air supply pipe 42 are fixed on the vehicle frame. The vehicle frame includes a compartment that seals various devices, and the compartment has a door. The vehicle frame facilitates the movement of the LNG emergency gas supply device, and the compartment plays the role of protecting various components.
