Title (EN) TURBINE AGGLOMERATED CALCIUM HYPOCHLORITE PARTICLE
(FR) PARTICULES D'HYPOCHLORITE DE CALCIUM AGGLOMEREES EN TURBINE
Abstract:
(EN) A feed material is obtained from mixing hypochlorous acid and a lime slurry: 2HOC1 + Ca (OH)2 ----> Ca (OC1)2.2H2O. The feed material is used to produce a hydrated calcium hypochlorite agglomerated particle that is produced in a turbine agglomerator and has a plurality of connecting links of recrystallized material bridging the small particles forming the agglomerate which has therein a plurality of pores created by the substantial evaporation of the layer of surface liquid. The surface tension and adhesion forced of the layer of surface liquid at least partially hold the agglomerated particle together prior to drying.
(FR) Un matériau d'alimentation est obtenu lorsqu'on mélange de l'acide hypochloreux et une bouillie de chaux: 2HOC1 + Ca (OH)2 ----> Ca (OC1)2.2H2O. Le matériau d'alimentation est utilisé pour produire une particule agglomérée et hydratée d'hypochlorite de calcium qui est produite dans un agglomérateur à turbine et comporte une multiplicité de liens de connexion en un matériau recristallisé reliant les petites particules constituant l'aggloméré. Celui-ci comporte une multiplicité de pores produits par l'évaporation conséquente de la couche liquide de surface. Les forces de tension et d'adhésion de surface de la couche liquide de surface retiennent ensemble, tout au moins partiellement, la particule agglomérée avant le séchage.
