Title: Process for hydration of quicklime and corresponding plant
Inventor: CELLA GIAN MARIO
IPC: C04B/
Filed: 1990-09-24
Granted: 1994-10-14
Abstract: This plant for hydration of quicklime has the specific feature of using in the process water previously used for the extraction of the particles of lime suspended in the smokes or vapours emerging towards a chimney, and created by the exothermic reaction. This is effected by spraying of water of suitable purity taken from the outside 16 onto the vapours passing in ducts for conveying smokes towards the outlet, so as to envelop in this the particles to be entrained downwards to the interior of a collection tank 12 placed before the feed to the lime hydration process. This tank is integrated with a dust separation cyclone 9 positioned above it, in order to collect the water directly. A grating positioned between the cyclone and the tank prevents any crusts detached from the walls of the cyclone from getting into the tank and hence into the single-screw pump 15. <IMAGE>
