Method and apparatus for heating the starting solid organic transferred in a heating chamber for recovery of the energy of the vaporization of these materials placed under vacuum.

摘要

The apparatus comprises a heating chamber (CC) that mechanically transfers solid materials on a filter screen and comprises multistage sprinklers with hot juice, juice preheaters (R1, R2, R3, Rn, Rn+1) circulated to each multistage sprinklers and powered by a heating steam at an increased pressure level, an intermediate chamber (CI) for storing the heated raw material, a vacuum chamber (CV) continuously fed from the intermediate chamber and connected to a condenser, steam jet ejectors (T1, T2, Tn-1) feeding the preheaters, and a device for regulating a condensation pressure of preheaters. The apparatus comprises a heating chamber (CC) that mechanically transfers solid materials on a filter screen and comprises multistage sprinklers with hot juice, juice preheaters (R1, R2, R3, Rn, Rn+1) circulated to each multistage sprinklers and powered by a heating steam at an increased pressure level, an intermediate chamber (CI) for storing the heated raw material, a vacuum chamber (CV) continuously fed from the intermediate chamber and connected to a condenser, steam jet ejectors (T1, T2, Tn-1) feeding the preheaters, and a device for regulating a condensation pressure of each preheaters. The solid materials are transferred on the filter screen by an endless screw or drag conveyors. The vacuum chamber comprises an inlet for allowing the distribution of solid material, and an anti-priming device. The emitted vapor does not contain solid or liquid particles. The preheaters are: condensers that are fed by the vapor emitted from the vacuum chamber and by the juice from the heating chamber; and multitubular surface type preheaters. The steam jet ejectors are mono- or poly-nozzles. The preheaters are equipped with a vacuum device comprising a single vacuum pump connected to n-pairs of valves or vacuum pumps connected with a vacuum beaker. An independent claim is included for a process for heating hydrated, mechanically transferred organic solid materials within a heating chamber.
