Emergent LNG supply device

Abstract

The invention discloses an emergent LNG supply device. The emergent LNG supply device comprises a gasification device, a first temperature gauge, a first pressure gauge, a second temperature gauge, a safety valve, a pressure regulation set and a second pressure gauge which are connected with one another in series in sequent through a gas transmission pipe, wherein the gasification device comprises a gasifier or a plurality of gasifiers which are connected in parallel with each other, so that the gasification efficiency is improved; a ball valve is mounted between the first temperature gauge and the first pressure gauge and is connected in parallel with a heating device; the gas transmission pipe on the back of the second pressure gauge is divided into a user pipe used for supply gas for users and a gas supply pipe used for supplying gas for the heating device; the gas supply pipe is connected to the heating device; when the outside temperature is extremely low, the natural gas transmitted to the heating device by the gas supply pipe is ignited, so that workers can conveniently heat the LNG. The emergent LNG supply device also comprises a frame capable of conveniently moving and a carriage arranged on the frame and used for sealing the devices; by virtue of the frame, the device can move more conveniently; the carriage plays a role of protecting the parts such as the gasification device, the first temperature gauge and the first pressure gauge.

Description

technical field

[0001] The invention relates to a gas supply device, in particular to an LNG emergency gas supply device capable of moving and conveniently gasifying and heating natural gas. Background technique

[0002] In the process of urban natural gas supply, rescue and maintenance operations of natural gas pipelines are often encountered. The use of emergency natural gas supply devices can effectively reduce the occurrence of gas outage accidents during emergency repair operations and ensure the safe and continuous use of gas by users.

[0003] At present, the natural gas supply device occupies a large area and is inconvenient to move; and when the outside temperature is too low, the gasification efficiency of the gasification device decreases, and the liquefied natural gas gasified by the gasification device is not completely gasified; the incomplete gasification Natural gas has a certain damage effect on pipelines. In the prior art, there have been devices for heati...
