Apparatus for the preparation of alkaline hyperoxide

Claim 1

AN APPARATUS FOR THE PREPARATION OF ALKALINE PEROXIDE FROM A CONCENTRATED AQUEOUS SOLUTION OF ALKALINE HYDROXIDE AND HYDROGEN PEROXIDE, COMPRISING A DOUBLE-ENVELOPE FLUID-TIGHT REACTOR HAVING A DOUBLEENVELOPE WALL, SAID REACTOR BEING PROVIDED WITH MEANS FOR COOLING AND FOR MAINTAINING THE TEMPERATURE WITHIN SAID REACTOR AT LESS THAN 10*C, MEANS FOR IMMEDIATELY DISPERSING SOLID ALKALINE HYDROXIDE PARTICLES AND FOR AGITATION, FIRST MEANS FOR INTRODUCTION OF A FIRST REAGENT, SECOND MEANS FOR INTRODUCTION OF A SECOND REAGENT, MEANS FOR DRAWING-OFF OF A CONCENTRATED AQUEOUS SOLUTION OF THE REAGENTS FROM SAID REACTOR AND GRID MEANS TO PREVENT EXIT FROM THE REACTOR INTO THE DRAWING-OFF MEANS OF LARGE PARTICLES OF ALKALINE HYDROXIDE, A STORAGE RECEPTACLE PROVIDED WITH COOLING MEANS TO MAINTAIN SAID SOLUTION COLD AND CONNECTED TO SAID REACTOR VIA SAID DRAWING OFF MEANS, MEANS FOR RECEIVING AND THEN SPRAYING THE SAID COLD SOLUTION, SAID RECEIVING AND SPRAYING MEANS COMPRISING AN ATOMISATION DEVICE OF THE SHEET OR FLAT JET TYPE AND FORMD OF POLYTETRAFLUOROETHYLENE, MEANS FOR PROVIDING THE RAPID AND PUNCTUAL DEHYDRATION OF MSAID COOL SOLUTION BY SHOCK HEATING AND FOR PROVIDING ALKALINE HYDROXIDE IN THE FORM OF A POWDER, COMPRISING A SCALER OR FLAKING DRIER HAVING AN INTERNALLY HEATED ROTATING CYLINDER FOR RECEIVING SAID COLD SOLUTION AS ATOMIZED FROM SAID ATOMIZATION DEVICE, SAID CYLINDER BEING PROVIDED EXTERNALLY WITH A COATING OF ELECTROLYTIC NICKEL, SAID CYLINDER BEING SITUATED WITHIN A FLUID-TIGHT COMPARTMENT HAVING A DRY ZONE AND A MOIST ZONE SEPARATED BY BAFFLE MEANS , SAID COMPARTMENT BEING PROVIDED IN SAID MOIST ZONE WITH A DEVICE FOR THE ASPIRATION OF MOIST AIR AND IN SAID DRY ZONE WITH SCRAPER MEANS FOR THE RECOVERY OF THE HYPEROXIDE BY SCRAPING FROM TH RUM AND WITH SOLIDS WITHDRAWAL MEANS FO THE REMOVAL OF THE SO-SCRAPED ALKALINE HYPEROXIDE.
