Embodiment 1
[0030] Such as figure 1 and figure 2 As shown, the embodiment of the present invention provides a device for filtering and purifying heavy water, including:
[0031] The box body 1, the box body 1 is preferably a square structure with a cavity formed inside, and a filter channel 11 for heavy water to flow through is provided in the box body 1, so that the inner cavity of the box body 1 forms a filter cavity. The filter channel 11 is filled with active adsorbents 12, wherein the active adsorbents 12 are preferably hydrophilic physical adsorption materials such as activated alumina, silica gel desiccant, but not limited to activated alumina, silica gel desiccant and other hydrophilic physical adsorption materials , and is not limited to one filling material, it can also be a mixture of several materials or other synthetic materials. The outer wall of the box body 1 is fixedly connected with the water inlet pipe 13 for communicating with the lower end of the filter channel 11,...
Embodiment 2
[0037] The difference from Example 1 is that, as figure 2 As shown, the filter channel 11 is a serpentine pipeline structure, which is mainly formed by staggered arrangement of fixed plates respectively fixed on the inner side walls of the box body 1, so that the filter channel 11 in the box body 1 can reach a suitable position in a limited space. Length, to improve the filtration efficiency of heavy water, wherein the length of the filter channel 11 ranges from 0.1-99m, by controlling the total length of the filter channel 11 within 100m, it is easy to obtain deuterium-depleted water with a deuterium concentration of <40ppm.
Embodiment 3
[0039] The embodiment of the present invention provides a method for filtering and purifying heavy water. Using the device for filtering and purifying heavy water described in the embodiment of the present invention includes the following steps:
[0040] S1, first connect the electric anode plate 2 with the positive pole of the power supply, then connect the electric cathode plate 3 with the negative pole of the power supply, so that an electric field is formed between the electric anode plate 2 and the electric cathode plate 3;
[0041] S2. After the electric field is formed, input the aqueous solution into the filter channel 11 along the water inlet pipe 13 of the box body 1, so that the heavy water containing the D-O chemical bond is adsorbed on the active adsorption piece under the action of the electric field, and is discharged from the water outlet pipe 14 of the box body 1. Collect the outflow deuterium-depleted water;
[0042] Wherein the active adsorption part 12 is p...
