Large continuous air supply type air-heated vaporizer

Abstract

The invention relates to a large continuous air supply type air-heated vaporizer. The large continuous air supply type air-heated vaporizer comprises a heat exchange fin tube bundle which is arranged between a liquid inlet and an air outlet and arranged in a matrix mode, the heat exchange fin tube bundle is divided into an undercooling section, an evaporation section and a heating section which are parallel from the liquid inlet to the air outlet, the undercooling section, the evaporation section and the heating section are connected between the liquid inlet and the air outlet in series, each of the undercooling section and the heating section comprises at least one row of heat exchange fin tubes, the evaporation section comprises a plurality of rows of heat exchange fin tubes which are connected in series. According to the air-heated vaporizer, the undercooling section, the evaporation section and the heating section of the heat exchange fin tube bundle are connected in series, the evaporation section comprises the plurality of rows of heat exchange fin tubes which are connected in series, the arrangement is reasonable, the structure is compact, the overall rigidity is high, the vaporizer is attractive and elegant in appearance, cryogenic fluids can be distributed to pipes evenly, bias current can be avoided, and requirements for high-flow continuous air supply are met.

Description

technical field [0001] The invention relates to an air-temperature gasifier, in particular to a large-scale air-temperature gasifier with continuous air supply. Background technique [0002] The air-temperature vaporizer is a new type of high-efficiency environmental protection and energy-saving device that uses air for heat exchange. It is mainly used to convert low-temperature (-145°C~-196°C) liquids, such as: LO2, LN2, LAR, LNG, LC2H4 and other media into normal temperature gas to meet the applications in various fields such as ceramics, steel, solar energy, electronics, shipbuilding, natural gas industry, and chemical industry. [0003] At present, the air-heated vaporizers commonly used in the market do not have high requirements for flow rate or floor space. When the user requires a gasifier with a large flow rate, it can only be combined with several air-temperature gasifiers with a smaller capacity (≤5000Nm3 / h). The installation cost, civil engineering cost, instal...

AI Technical Summary

Problems solved by technology

When the user requires a gasifier with a large flow rate, it can only be combined with several air-temperature gasifiers with a smaller capacity (≤5000Nm3 / h). The installation cost, civil engineering cost, installation material and procurement cost are greatly increased, and the floor area is increased

[0004] In some special working conditions, it is required to use a gasifier with a large flow rate and a small footprint, and the above existing solutions cannot meet the user's requirements
