Novel air bath type vaporizer

Abstract

The invention relates to a novel air bath type vaporizer. A plurality of fin heat exchange tubes form a multi-row and multi-line array side by side along the longitudinal direction and the transverse direction; the fin number of the fin heat exchange tubes is gradually increased from the liquid inlet direction of a fluid medium to an air outlet direction; the bottom of each fin heat exchange tube in each line of fin heat exchange tubes is communicated with one low communicating pipe; the quantity of the lower communicating tubes is equal to the line number of the fin heat exchange tubes; at least one third of lower communicating tubes in the total lower communicating tubes is connected with one liquid inlet pipe which is horizontally arranged in parallel; the rest two thirds of lower communicating tubes are connected with one air outlet pipe which is horizontally arranged in parallel. According to the novel air bath type vaporizer disclosed by the invention, the arrangement of a header meets the transfer of the fluid medium among the fin heat exchange tubes in all the lines; the quantity of the fin heat exchange tubes is increased from the inflow direction of the low-temperature fluid medium to the air outlet direction, so that the fin heat exchange tube with the low-temperature fluid medium obtains a greater heat exchange space through fewer fins, further full heat exchange is realized, the fin heat exchange tubes are not easy to ice, and a good vaporization effect is guaranteed.

Description

technical field [0001] The invention relates to vaporization equipment, in particular to a novel empty bath vaporizer. Background technique [0002] An air bath vaporizer is a device in which a liquid gas is heated in a vaporizer / evaporator until it vaporizes (turns into a gas). It uses the flow of air to heat a cryogenic liquid in an air-bath vaporizer, converting the liquid to a gas. At present, the flow rate of the existing vaporizer is large and the pressure is low, so there is an urgent need to involve an empty bath type vaporizer that meets the large flow rate. Contents of the invention [0003] Aiming at the above-mentioned existing problems, the applicant made research and improvement, and provided a new type of air-bath vaporizer, which is easy to install and maintain, so that it not only meets the large flow design required by customers, but also has a good heat exchange effect, and at the same time improves the Vaporization efficiency. [0004] The technical ...
