Description

Method for treating tritium water by photo-thermal concerted catalysis
Technical Field
The invention belongs to the field of radioactive waste treatment, and particularly relates to a method for treating tritium water by photo-thermal concerted catalysis.
Background
For tritium water treatment, VPCE, LPCE and CECE are currently common treatment methods, and H is utilized as the core2And (3) replacing tritium in the tritium-containing water to finish tritium removal treatment of the tritium-containing water. However, to increase the efficiency of the replacement, H2The ratio to tritiated water is often 3: 1 or higher, so that tritium is displaced in H2Is diluted, resulting in an increased burden on the isotope separation unit. In addition, VPCE is generally operated at about 200 ℃, energy consumption is large, LPCE relates to preparation of a hydrophobic catalyst, the process is complicated, the catalyst is easily covered by liquid water to be deactivated, CECE needs to be introduced into electrolysis equipment, and energy consumption is also too high.
In recent years, scholars replace hydrogen isotope exchange reaction with water vapor exchange reaction without introducing H2So that the HT produced is not diluted. Water-vapor transformation reaction: HTO + CO → CO2And + HT, the reaction principle is that a certain amount of CO is introduced, and T of the tritiated water is replaced, so that tritium removal operation of the tritiated water is realized. The catalyst used in the reaction is a conventional hydrophilic catalyst, and has the advantages of simple preparation and high stability.
For the water-vapor shift reaction, the reaction is exothermic from a thermodynamic point of view, i.e., the equilibrium conversion decreases as the temperature increases, so that a lower reaction temperature is advantageous for obtaining a higher conversion. In addition, because tritium is radioactive, it easily permeates into the environment through the container wall under high temperature conditions, causing radioactive contamination, and thus lower operating temperatures are safer. However, from the aspect of dynamics, the temperature is reduced, the chemical reaction rate is reduced, and the high-efficiency treatment of the tritiated water is difficult to realize in engineering application. Therefore, the conventional technology at present cannot simultaneously meet the requirements of high conversion rate, low tritium permeation quantity and high reaction rate when the tritium water is treated by adopting a water-vapor shift reaction.

Based on the device for treating tritium water by photo-thermal concerted catalysis shown in figure 1, the method for treating tritium water by photo-thermal concerted catalysis comprises the following steps:
a. uniformly mixing a catalyst 5 and an adsorbent 6, adding the mixture into a reactor 3, turning on a heater 1, and heating the reactor;
b. converting tritium water HTO into water vapor and CO through a gasifier 2, uniformly mixing, and introducing into a reactor 3;

The invention uses a semiconductor material responsive to ultraviolet light as a catalyst support such as TiO2,Co3O4And introducing a light source for assisting thermal catalysis, reducing the reaction temperature and realizing the rapid treatment of tritiated water at the temperature close to normal temperature. The method can be applied to places where tritium water is generated, such as fusion devices, nuclear power stations and the like.
Further, the light source wavelength of the xenon lamp 4 is 300-700 nm, and the power is 100-300W;

Oxygen vacancies, a common defect structure of catalysts, can be used to activate water molecules and participate in chemical reactions therewith.

After the light source is introduced, the catalyst can generate a large amount of oxygen vacancies at the temperature of 50-150 ℃. The invention realizes the water-vapor transformation reaction at the near normal temperature by means of light source assisted thermal catalysis, and can realize safe, efficient and rapid treatment of tritium water.
