Abstract

The invention relates to a system and method for strengthening LNG air-temperature type gasification by utilizing photovoltaic power generation and heat radiation. During the daytime, a high efficiency photovoltaic power generation system transmits current to a heating wire, the heating wire heats superconducting liquid and further heats a base in a heat conducting mode, and the base radiates heatto a gasifier; at night, a storage battery pack transmits current to the heating wire, an electrical heated tube conducts heat to the base, and the base radiates the heat to an LNG air-temperature gasifier; and an energy transfer system is arranged behind a solar back plate in the high efficiency photovoltaic power generation system to transfer waste heat behind the solar back plate to a steel plate, and the steel plate transfers the heat to the LNG air-temperature gasifier in a heat radiation mode. The system uses solar energy and the waste heat at the back of the solar panel to transfer theheat to the gasifier in a photovoltaic power generation and heat radiation mode, the power generation efficiency of the solar panel is improved, the service life of the solar panel is prolonged, thegasification efficiency of the LNG air-temperature gasifier is improved, and the phenomena of frosting and icing on the surface of the gasifier are reduced.

Description

technical field [0001] The invention relates to the fields of photovoltaic power generation technology, energy storage technology, thermal radiation technology and liquefied natural gas gasification technology, and in particular to a system and method for enhancing air-temperature gasification of LNG by utilizing photovoltaic power generation and thermal radiation. Background technique [0002] Natural gas can be liquefied into liquid at -162°C and normal pressure, called liquefied natural gas (LNG for short). Since the volume of natural gas can be reduced by 600 times after liquefaction, it is convenient for economical storage and transportation. Therefore, many countries and regions around the world trade natural gas in the form of LNG. At the same time, many countries use LNG to supply gas to areas in their country that are far away from gas fields and have no long-distance pipelines. When LNG is used as a fuel or an industrial raw material, a certain amount of heat must...

Problems solved by technology

[0003] The air-temperature gasifier uses the air in the atmospheric environment to gasify LNG. When the temperature is low, the surface of the gasifier is prone to frost and ice, which seriously affects the gasification capacity of the gasifier. Therefore, two sets of air are generally used. Warm gasifier, when one group is defrosting and deicing, the other group operates to gasify LNG, which not only increases equipment investment, but also occupies a large area

At the same time, during the gasification of LNG by the air-temperature gasifier, the moisture in the air will condense when it encounters a cold surface. According to calculations, in an environment of 15°C and a relative humidity of 60%, the gasification produces 1Nm 3 Natural gas will produce 0.1L condensed water, which is usually discharged directly, causing a lot of waste and affecting the surrounding ecological environment
