A gasification device for lng

Abstract

The invention discloses a gasification device for LNG. The gasification device comprises a first tank car connector, a second tank car connector and a third tank car connector, all of which are correspondingly arranged. A first liquid-phase outlet of an LNG tank car is connected with the first tank car connector through a first unloading hose. The first tank car connector is connected with a liquid inlet emergency shutoff valve through a third pipeline. The liquid inlet emergency shutoff valve is connected with a liquid inlet connector of an LNG storage tank through a fourth pipeline. A liquidoutlet connector of the LNG tank car is connected with an air temperature type vaporizer through a twelfth pipeline. The gasification device has the beneficial effects that energy consumption is low,unloading is stable, BOG generated through self-pressurization is used in a station after being treated, and safety and convenience are achieved; LNG is gasified through the air temperature type vaporizer and a water bath type vaporizer, energy consumption is low, a liquid inlet pipe and a liquid outlet pipe are provided with emergency shutoff valves, and safety and reliability are achieved; andthe water bath type vaporizer is provided with a bypass pipeline, usage is not needed under the situation that the outside temperature is high, the resource is saved, the service life of equipment isprolonged as well, and the LNG can be supplemented into the station to be used after being gasified.

Description

technical field [0001] The invention relates to the technical field of LNG unloading, in particular to a gasification device for LNG. Background technique [0002] LNG is the abbreviation of English liquefied natural gas (liquefied natural gas). The main component is methane. LNG is colorless, odorless, non-toxic and non-corrosive, and its volume is about 1 / 600 of the volume of the same amount of gaseous natural gas. Compared with gasoline, diesel and compressed natural gas (CNG), LNG has obvious advantages such as high safety, strong economy, small environmental negative effects, and high energy storage density. As a vehicle fuel, LNG is widely used in urban buses, heavy trucks and intercity buses, and the supporting LNG filling stations are also developing rapidly. Existing LNG filling stations or gasification stations use submersible pumps for unloading, filling and filling, which have disadvantages such as high investment and operating costs and low reliability.

Problems solved by technology

Existing LNG filling stations or gasification stations use submersible pumps for unloading, filling and filling, which have disadvantages such as high investment and operating costs and low reliability

Moreover, the BOG generated in the station and in the LNG tanker cannot be effectively used, which is easy to generate waste
