Liquid vaporizer with liquid jetting preventing effect

Abstract

The invention discloses a liquid vaporizer with energy-saving and efficient heat exchange effects. The liquid vaporizer comprises a liquid storage cavity, a gas storage cavity, multiple liquid feedingpipes and a set of heat exchange fins. The aluminum (or copper) fins with a heat exchange enhancing effect are arranged outside liquid pipes to enhance heat exchange. The liquid storage cavity is formed below the gas storage cavity. The liquid storage cavity and the gas storage cavity are connected through one or more guide pipes. Liquid guide pipes are all arranged in the heat exchange fins. Theheat exchange fins are arranged on the outer wall faces of the liquid guide pipes through physical methods such as hydraulic expansion, so that tight contact surfaces are formed between the heat exchange fins and the liquid guide pipes. The liquid storage cavity is located below the heat exchange fins, and in order to guarantee that the liquid storage cavity is not directly heated, the liquid storage cavity is not surrounded and heated by the heat exchange fins. In order to avoid vaporization of small-flow liquid on the edge of the vaporizer, namely an air jetting phenomenon, the method thatliquid flows into the vaporizer through the multiple pipes is adopted, so that the vaporizer adapts to the goal that gas is stably emitted in both small flow and large flow. Due to the fact that the liquid guide pipes and the heat exchange fins of the vaporizer are integrated, the heat conduction area is large, heat conduction of the gas outside the liquid feeding pipes can be accelerated, and heat exchange efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of vaporizers for energy-saving equipment, in particular to a high-efficiency energy-saving vaporizer with safe use and high reliability, in particular to a vaporizer for a water vaporization process. Background technique [0002] In laboratory or industrial production, it is often necessary to vaporize liquid into gas and enter the reactor for reaction, especially the reaction of water vapor. For the current vaporizers, electric heating is mostly used, and they are installed in pipelines or liquid storage containers. After the liquid in the container is heated, steam is generated, and then flows out through the pipeline for use. This process consumes a lot of energy. Due to the high loss of energy in the field of vaporizers, the present invention adopts a method in which multi-pipe liquids with finned tubes enter the vaporizer, uses gas waste heat to heat the liquid to make it vaporize, and enhances heat tr...
