Long-time iodine flow supply device

Abstract

The invention provides a long-time iodine flow supply device, and relates to the technology of gas supply of a continuous wave oxygen-iodine chemical laser. The main body of the device has two parts: an electric heating iodine vapor storage tank and a combustion chamber for the combustion of two types of gas. The electric heating iodine vapor storage tank enables solid iodine to be heated to a certain temperature and enables the solid iodine to be changed into liquid iodine. Moreover, there is iodine vapor with a certain saturated vapor pressure on the liquid level. The combustion chamber is a closed space which is used for the combustion of carbon monoxide and oxygen, and the generated high-temperature and high-pressure gas enters the iodine vapor storage tank after the temperature adjustment through diluent gas. High-temperature carbon dioxide gas enters the liquid phase of the iodine vapor storage tank and then forms bubbles, thereby enabling heat energy to be transferred to the liquid iodine and enabling the iodine to be vapored into iodine vapor, wherein the bubbles comprise iodine vapor with a certain density. When the bubbles continue to rise in the liquid phase, the phenomenon of mass and heat transfer continues to happen till the balance is reached. The bubbles flow out from the liquid phase, enter a gas phase, pass through a gas supply pipe and then enter a laser main body.

Description

technical field [0001] The present invention relates to the supply of materials for oxygen iodine chemical lasers. technical background: [0002] Iodine vapor is one of the necessary materials for continuous wave oxygen-iodine chemical lasers. The method of its generation determines the stability, volume and continuity of the iodine vapor flow. The method of production is mainly physical evaporation method, but also chemical method. [0003] The physical evaporation method is to heat the solid iodine into a liquid at high temperature, and control the saturated vapor pressure of the iodine vapor on the surface of the liquid by adjusting the temperature of the iodine liquid. When the air release valve of the closed container is opened, the iodine vapor can flow out into the gas supply pipeline. The specific realization is that the iodine crystal is placed in a vacuum-tight heatable stainless steel tank, and the tank is equipped with accessories such as temperature measurement...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage of the iodine vapor supply device of this electric heating evaporation method is that the iodine vapor gradually decreases during the supply process, resulting in a gradual decrease in the flow rate of the iodine vapor

The reason is that the stainless steel heating tube is placed in the iodine liquid and the conduction efficiency is slow, which cannot meet the continuous evaporation of the iodine liquid.
