DEVICE FOR DECONTAMINATION OF LIQUID RADIOACTIVE WASTE low and medium levels of radioactivity

摘要

The utility model relates to the treatment of liquid radioactive wastes (LRW) low and medium level activity, including for removing moisture from the different solutions, liquid chemical production waste (wastewater), to increase their concentration, i.e. volume reduction. The purpose of the utility model is to expand the functionality. The technical result of this device is the ability to conduct simultaneous evaporation process to obtain a condensate suitable for discharge in open water and concentration produced during most complete evaporation of the brine with its subsequent deposition on a fine mesh within a single flash vessel. The technical result is achieved in that the device for disposing of liquid radioactive waste of low and intermediate level of radioactivity, comprising a vertically disposed evaporator container with a lid placed inside the annular tank adapted to form a closed funnel narrow part downwardly flanged connector and fine mesh, supply pipe the processed solution and a heating unit which is designed as a hydrodynamic generator mounted in the inner container, which is arranged in cf. edney part of the flash tank, wherein the inner container is secured on the opening cover flash vessel on which the tubes for supplying and discharging processed solution pair, and inside the vaporization container in the lower narrow portion thereof, is installed fine screen, with; This inlet nozzle of the inner container mounted in its lid is connected via a conduit with a pump output, the input of which is connected with an outlet of the annular tank disposed in its bottom and inlet annular tank disposed on a side surface which is connected via a conduit with an outlet the inner container is at the side surface of the inner container, a removable lid above the evaporation vessel. Moreover, inside the vaporization container in the lower part may be mounted structure of fine mesh.
