Visualization experiment device for deep-low-temperature condensation heat exchanging process

Abstract

The invention discloses a visualization experiment device for a deep-low-temperature condensation heat exchanging process. The visualization experiment device comprises a vacuum box, a reboiler, a steam exhaust pipe, a condensing device and a liquid storage tank, wherein the reboiler is used for containing and gasifying deep-low-temperature liquid, the steam exhaust pipe is communicated with the upper portion of the reboiler and used for outputting steam, the condensing device is communicated with the steam exhaust pipe and used for receiving and condensing the steam, the liquid storage tank is used for providing refrigerating capacity for the condensing device, and the side wall of the vacuum box is provided with a transparent light window. After being heated and evaporated through the reboiler, the deep-low-temperature liquid enters the condensing device through the steam exhaust pipe and flows back to the reboiler after being condensed, visualization is achieved by arranging the visual light window, data can be measured accurately in real time, and condensation of mixed gases and the influence on condensation by non-condensable gases can be researched by injecting other gases different from the researched gas. When the liquid level in the reboiler and the pressure of the steam exhaust pipe are unchanged, the heating quantity of the reboiler is equal to the steam condensation heat exchanging quantity on a test board, and therefore the steam condensation heat exchanging quantity can be measured indirectly.

Description

technical field [0001] The invention relates to a condensation heat transfer experimental device, in particular to an experimental device capable of realizing the measurement and visualization of the condensation heat transfer of a deep-low temperature fluid. Background technique [0002] Industrial gas is the "blood" of modern industry, and its application covers many important fields such as iron and steel, metallurgy, chemical industry, shipbuilding, automobile, medicine, food, electronics, petroleum, aerospace and so on. With the rapid economic development, the demand for industrial gases is also surging. At present, industrial gases are mostly separated from air, and the air separation (referred to as air separation) device is a device that produces oxygen, nitrogen and other rare gases from air. The scale of modern air separation plants is getting larger and larger, and the problem of energy consumption has become more prominent. [0003] The main condensing evaporat...
