Embodiment Construction

[0035] Such as figure 1 and figure 2 As shown in , a solids separator 1 for separating first and second solids of different densities comprises a first internal vertical partition 2, wherein the diameter and density of the first solid is greater than the diameter and density of the second solid, so Said first internal vertical partition 2 forms a channel in the lower part and forms two compartments 1A and 1B on the channel of the fluidized solids, the pressurized seal between the two compartments being provided by the height H of the fluidized solids, The fluidization of each compartment is independently controlled by the two fluidization gas inlets 3A and 3B in order to obtain the separation of the first and second solids in the first compartment 1A and the transfer of the first solid to the second compartment 1B. velocity field.

[0036] According to the invention, the first compartment 1A is provided with internal obstruction means deflecting the path of the solids.

Abstract

The invention relates to a separator of solids intended for separating first and second solids, the diameter and density of the first solids being larger than the diameter and density of the second solids, and including a first substantially vertical internal baffle (2) forming a passage in the low portion of the separator and which forms two compartments (1A, 1B) on the passage of the fluidized solids, the fluidization of each compartment being independently controlled by two fluidization gas inlets (3A, 3B), in order to obtain the desired velocity field for separating the first and second solids in the first compartment (1A) and discharging the second solids through a vent (8), as well as for transferring the first solids into the second compartment (1B). According to the invention, saidfirst baffle (2) is provided on at least one of its substantially vertical faces with fluidization gas ejectors (E2) and the first compartment (1A) is equipped with an internal obstacle arrangement deflecting the path of the solids and at least partially provided with fluidization gas ejectors (E4A) directed towards said first baffle (2).

Description

technical field [0001] The invention relates to a solids separator especially for combustion equipment Background technique [0002] Such a device for burning carbonaceous residues is described in patent FR 2850156 . [0003] This equipment includes a reactor for reducing oxides, a first cyclone, an exchanger for flue gas heat recovery, a reactor for oxidizing oxides, a second cyclone, and a An exchanger for the temperature of the oxides in which the oxides reduced and then oxidized in the two reactors are circulated. According to this prior art, solid combustible materials are crushed before entering the oxide reduction reactor. The oxide is first reduced by contacting the oxide with a fuel which reacts with oxygen released from the oxide; the oxide is then regenerated by contacting the reduced oxide with air. The reduced size solid fuel particles allow for more complete and rapid combustion and produce nearly 100% fly ash. [0004] This plant, operating at atmospheric ...
