Air temperature type vaporizer for achieving frost inhibition on bionic surface and frost inhibition method

Abstract

The invention discloses an air temperature type vaporizer for achieving frost inhibition on a bionic surface and a frost inhibition method. The air temperature type vaporizer comprises a plurality of fins and a plurality of vaporizing pipes, the heads and the tails of the vaporizing pipes communicate with a low-temperature liquid inlet and a gas outlet correspondingly, and the multiple rows of fins are connected in the vertical direction of the vaporizing pipes. Flow guide grooves or hydrophilic fiber bundles for conveying dew are arranged on the surfaces of the upper parts of the fins and the surfaces of the portions, between the vaporizing pipes, of the fins, and the flow guide grooves extend into dew collecting devices on the two sides of the fins. The hydrophilic fiber bundles extend to two sides of the fins, and weights are connected below the hydrophilic fiber bundles and are in butt joint with dew collecting devices. After entering the vaporizer, air is subjected to heat exchange, and most of water in the air is condensed into the dew on the surfaces of the fins. The surfaces of the channels have hydrophilicity, the mode that a plant vessel conveys water is simulated, the dew on the fins rapidly leaves the vaporizer through the channels, the dew is prevented from making contact with the area, with the temperature being lower than zero DEG C, of the vaporizer, moisture capable of frosting in the air is reduced, the frosting thickness is reduced, and the heat exchange rate is increased.

Description

technical field [0001] The invention belongs to the technical field of low-temperature liquid gas gasification, and relates to an air-temperature vaporizer and a frost suppression method for vaporizing liquid gas to suppress frost. Background technique [0002] Various liquefied gases are widely used in the industrial field. These liquefied gases are transported and stored in the form of liquids, and are converted from low-temperature liquids to normal-temperature gases through a gasification system when in use. The core equipment of the gasification system is the gasifier. [0003] The air-temperature vaporizer uses normal temperature air to exchange heat with the low-temperature liquid in the pipeline, which has the advantages of low energy consumption and low pollutant emissions. It has significant advantages in energy saving and emission reduction. [0004] At present, during the operation of the air-heated vaporizer, due to the low temperature of the cryogenic liquid...

AI Technical Summary

Problems solved by technology

In the process of heat exchange with the flowing air, the water vapor in the air undergoes a phase change, and adheres to the surface of the pipe and fins through condensation or sublimation, and frosts on the surface of the gasifier, reducing the heat transfer rate , which reduces the running time of the equipment and affects the working efficiency of the equipment
