Laboratory air tritium removal system

Abstract

The invention discloses a laboratory air tritium removal system and relates to the technical field of tritium removal purification. The system includes a closable laboratory, wherein the tritium leakage monitoring system is used for monitoring the content of tritium in the closable laboratory; the air tritium removal system is used for treating tritium-containing waste hydrogen; an air inlet and an air outlet of the air tritium removal system are both communicated with the interior of the sealable laboratory; the air tritium removal system sequentially comprises a filter, a refrigeration dryer, a drying bed, a catalytic oxidation bed, a condenser and an adsorption bed from an air inlet to an air outlet, wherein the fan is arranged at any position of air path circulation, and the tritium leakage monitoring system is in signal connection with the fan and a control system capable of sealing a laboratory sealing door. According to the laboratory air tritium removal system, moisture in airis removed firstly, then gaseous tritium and trace organic tritium in waste gas are oxidized into tritiated water through catalytic oxidation, an adsorption bed is adopted for absorbing tritiated water vapor, and the air ,after tritium removal, is subjected to circulation treatment till the air reaches the standard.

Description

technical field [0001] The invention relates to the technical field of tritium removal purification treatment, in particular to a laboratory air tritium removal system. Background technique [0002] Tritium is an important and precious resource. With the deepening of fusion energy development, the design and planning of large-capacity fusion reactors put forward higher and higher requirements for tritium safety protection. In the fusion reactor tritium factory system, the occurrence time of the abnormal release accident of tritium is unpredictable, and once the accident occurs, the amount of tritium released is often relatively large. It is very likely to cause professional workers to be exposed to excess tritium, which will affect the health of professional workers, even cause huge economic and property losses, and cause huge impact and catastrophic damage to the public and the environment. Contents of the invention [0003] The purpose of the present invention is to pro...
