The present invention relates to an LNG
frost suppression and efficiency-enhancing air-bath type gasification
system utilizing a
solar heat pump and air circulation. The
refrigerant absorbs solar
radiation and ambient heat to heat the air in the air supply
pipe; the
ambient air is dehumidified by the preheater and flows through the condenser to absorb the heat of the
refrigerant, and then enters the wind hood to heat the LNG in the gasifier, the air is further dehumidified, and the cooled and dried air flows into the air supply
pipe through the return air
pipe to form an air circulation; a portion of the LNG flowing out of the
storage tank enters the preheater, and by controlling the LNG flow rate, the LNG flowing out of the preheater is ensured to remain in a
liquid state, and the preheated LNG is merged into the LNG flowing out of the
storage tank; the wind hood equipped with tempered glass produces a
greenhouse effect inside. The invention makes full use of the cold energy of LNG to reduce the
moisture content of the circulating air, utilizes
solar energy and air energy to heat the circulating air, and creates a
microclimate suitable for the efficient operation of the air-temperature gasifier
frost suppression, which is energy-saving and
environmentally friendly, and has good economic and
social benefits.
