Abstract

The invention relates to an LNG air temperature type gasification device utilizing photovoltaic power generation and a method of the LNG air temperature type gasification device. A substrate of a photovoltaic power generation device is in a dual curve shape, the top of the substrate is not sealed, an opening is formed in the substrate northwards, an electric wire is connected between the sides of the opening, and a thin film solar cell panel is laid on the outer surface of the substrate. An LNG air temperature type gasifier is supported in the photovoltaic power generation device. MI heating cables are wound around a gasifier inlet pipeline and a gasifier outlet pipeline, and connected with the electric wire. Electric energy generated by the photovoltaic power generation device is converted into heat energy through the MI heating cable on the gasifier inlet pipeline to heat inlet LNG. When the temperature of outlet natural gas is lower than 5 DEG C, the outlet natural gas is heated through the MI heating cable on the gasifier outlet pipeline, so that energy consumption generated by subsequently utilizing a water bath type gasifier for reheating is eliminated or reduced. According to the LNG air temperature type gasification device, solar energy is fully utilized, the gasification capacity of the LNG air temperature type gasifier is guaranteed, and the phenomenon that the outer surface of the LNG air temperature type gasifier is frosted and frozen is relieved or eliminated.

Description

technical field [0001] The invention belongs to the technical field of LNG gasification utilizing photovoltaic power generation, in particular to an LNG air-temperature gasification device utilizing photovoltaic power generation and a method thereof. Background technique [0002] Liquefied natural gas (LNG for short) is an important source of city gas in my country, which needs to be gasified from a liquid state to a gaseous state before being supplied to users. Since the temperature of LNG is -162°C, an LNG air-heated vaporizer is often used to vaporize LNG by absorbing the heat of the surrounding air. However, the gasification capacity of the air-heated gasifier is greatly affected by the ambient temperature. When the temperature is low (especially in severe cold regions), the gasification capacity may not meet the requirements, and the water vapor in the air will be gasified. The outer surface of the device is condensed and solidified, and frost and ice appear. For this...
