Embodiment Construction
[0015] Such as figure 1 , figure 2 As shown, an integrated filter adsorber with both radioactive aerosol filtration and iodine adsorption includes a housing 1 and a filter adsorption filter element 2 arranged in the housing 1. The filter adsorption filter element 2 includes a filter element housing 3, a filter element housing The two sides of the body 3 are open, and one side of the filter housing 3 is provided with a plurality of activated carbon fiber rods 4. The two ends of the activated carbon fiber rods 4 are connected to the inner wall of the filter housing 3, and the adjacent activated carbon fiber rods 4 With supporting layer 5;
[0016] The filter adsorption element 2 is installed in the adsorber housing 1, one side of the adsorber housing 1 has an air inlet, and the air inlet communicates with the inner cavity of the adsorber housing 1 and the inner cavity of the filter housing 3.
[0017] Furthermore, the activated carbon fiber rod 4 is impregnated with one or two solu...

The invention provides an integrated filter adsorber with radioactive aerosol filtration and iodine adsorption functions. The integrated filter adsorber comprises a shell and a filter adsorbing filterelement arranged in the shell, the filter adsorbing filter element comprises a filter element shell, the two sides of the filter element shell are open, a plurality of activated carbon fiber rods arearranged at an opening in one side of the filter element shell, the two ends of the activated carbon fiber rods are connected with the inner wall of the filter element shell, and a supporting layer is arranged between the every two adjacent activated carbon fiber rods; and the filter adsorbing filter element is mounted in the adsorber shell, an air inlet is formed in one side of the adsorber shell, and the air inlet communicates with an inner cavity of the adsorber shell and an inner cavity of the filter element shell. The filter adsorber has the radioactive aerosol filtration function and the radioactive iodine adsorption and purification functions, on the one hand, the operation costs of a nuclear power plant, other nuclear facility ventilation systems and gas treatment systems can be saved, and on the other hand, the treatment and dispose costs of final radioactive waste can be saved.
Description
Technical field [0001] The invention relates to a method and equipment for aerosol filtration and iodine adsorption purification of air purification, in particular to an integrated filter adsorber with both radioactive aerosol filtration and iodine adsorption. Background technique [0002] At present, the ventilation systems or radioactive gas treatment systems of nuclear power plants or other nuclear facilities use high-efficiency filters to filter and remove radioactive aerosols in the air or gas, and use iodine adsorbers filled with impregnated granular activated carbon to adsorb and purify radioactive iodine (including elemental iodine). , Organic iodine and other radioactive iodine compounds), these high-efficiency filters and impregnated granular activated carbon iodine adsorbers are classified into different types of radioactive waste according to the amount of radioactivity they filter or adsorb, and undergo corresponding treatment and final disposal, and incur final waste...
