Embodiment 1

[0017] A thermal storage type liquefied natural gas gasification device is manufactured. Such as figure 1 As shown, the device includes: a heat exchanger 4; it is characterized in that it also includes a heat insulating shell 1, a heat insulating top cover 2, a heat conducting partition 9, a spray pipe 5, a natural gas collecting pipe 7, a heat storage medium 10, a heat exchange Device 4, natural gas steam inlet pipe 12, electronic igniter 13, bypass pipe 14, bypass valve 15; wherein, the heat conduction partition 9 and the heat insulation shell 1 are fixedly connected, and the heat exchanger 4 is fixed in the heat conduction partition 9, The upper shell side of the heat exchanger 4 is the liquefied natural gas gasification chamber, the lower shell side of the heat exchanger 4 is filled with heat storage medium, the natural gas steam inlet pipe 12 is coaxially fixed inside the inlet pipe 11 of the heat exchanger, and the electronic igniter 13 It is fixed in the inlet pipe 11 ...

Embodiment 2

[0022] Utilize the heat storage type liquefied natural gas gasification device gasification natural gas of embodiment 1, concrete steps are as follows:

[0023] (1) The natural gas produced by the evaporation of the liquefied natural gas storage tank is passed into the heat exchanger through the inlet pipe 11 of the heat exchanger, and the electronic igniter 13 is ignited and burned, and the heat of combustion is transferred to the shell side through the lower part of the heat exchanger with excellent thermal conductivity The heat storage medium paraffin carries out phase change heat storage, and the exhaust gas after combustion is discharged through the outlet pipe 6 of the heat exchanger;

[0024] (2) The liquefied natural gas is sprayed onto the surface of the heat exchanger 4 through the spray pipe 5, and the cold energy is transferred to the wall surface of the heat exchanger 4;

[0025] (3) The heat exchanger 4 continuously transfers the heat of the paraffin 10 to the na...

Abstract

A heat accumulating gasifier for liquefied natural gas is disclosed. The natural gas generated by evaporation of liquefied natural gas in storage tank is burning at the bottom of gasifier. The heat generated by said combustion is transferred via heat exchanger to the heat accumulating medium. The accumulated heat is then used to gasify the liquefied natural gas. Said gasifier is composed of a heat exchanger, an insulating gasifying case containing said heat exchanger and divided into the gasifying cavity containing showering tube of liquefied natural gas and natural gas collecting tube and the heat accumulating cavity full of heat accumulating medium, and an igniter.

Description

technical field [0001] The invention relates to a gasification device for liquefied natural gas, in particular to a heat storage type gasification device for liquefied natural gas. Background technique [0002] At present, common LNG gasification devices are air-temperature tube-and-tube gasifiers or electric heating tube-and-tube gasifiers, neither of which can utilize the natural gas produced by the evaporation of LNG storage tanks. The air-temperature tubular gasifier is divided into natural circulation air cooling type and forced convection air cooling type. Since the natural gas liquid at -162°C is gasified in the gasifier, the heat transfer temperature difference is too large. After a period of gasification , the surface of the gasifier is covered by cold frost, which leads to the reduction of the evaporation capacity of the gasifier, and this kind of gasifier has a working time limit, generally no more than 8 hours of continuous work, and the forced convection air-coo...
