Abstract
The utility model discloses an adsorbing and filtering device for radioactive wastewater. A filtering bag is convenient and rapid to replace. A top cover is opened and a pressing component is loosened automatically; after the pressing component is taken away, the filtering bag containing filtering material is rapidly taken out from the upper part, the filtering bag containing new filtering material is put in and the pressing component and the top cover are arranged in place. Then new adsorption operation starts. Radiation to people can be reduced to the greatest extend by rapid replacement of the filtering bag. Filtering material and filtering bags with characteristic adsorption can be chosen or replaced for special nuclide, so that the removal rate of radioactive nuclide can be effectively increased. In addition, in an adsorber, a coupling layer which can be compressed surrounds and covers the outer side surface of the filtering bag, so that the radioactive wastewater flows through the filtering bag and flows out from water outlet meshes at the bottom of the filtering bag and a fixed frame after the radioactive wastewater flows in from a water inlet at the upper part of a barrel body and the radioactive wastewater is avoided from flowing out from the side of the filtering bag to avoid short circuit flow. The radioactive wastewater flows through the filtering bag from up to down, so that the nuclide in wastewater can be fully adsorbed by the filtering material in the filtering bag and the nuclide in the wastewater is removed thoroughly.
