US 5,177,876 A · Reactor installation for countercurrent treatment of gases and bulk solids

Abstract

The invention relates in general to a reactor installation for countercurrent treatment of gases and bulk solids and, in particular, to a moving bed reactor installation with at least one reaction chamber which latter has at least one inlet and at least one outlet for passing therethrough a solid material present in bulk from the top toward the bottom countercurrently to a gas, at least one flow baffle by means of which the gas is conducted from the bottom toward the top into the bulk material present in the reaction chamber, at least one first sliding surface for the bulk material, arranged above the reaction chamber and terminating at its upper end into a feeding shaft or hopper and supplying the inlet of the reaction chamber with bulk material, and at least one second sliding surface for the bulk material, arranged below the outlet, wherein the sliding surfaces are inclined regarding the horizontal to such an extent that the bulk material is conveyed in the inclined direction solely under the action of gravity.

Process for conducting a stream of bulk material in at least one moving bed reactor wherein the bulk material is introduced into an upper end of the moving bed reactor by way of a first inclined sliding surface and is discharged at an outlet of a second inclined sliding surface, wherein the bulk material is conveyed in a direction of inclination on both sliding surfaces solely under the effect of gravity, characterized in that:

said bulk material is introduced from a point above the reactor, moves laterally along the first inclined sliding surface, and is discharged at the outlet of the second sliding surface which is inclined in the same direction of inclination;
wherein, with a row of reactors, the bulk material to be fed to a single reactor is branched off from a stream of the bulk material common to several reactors in the row, and several streams of the bulk material, after being separately carried off, are recombined in a single discharge shaft.

Reactor installation, in particular a moving bed reactor installation, comprising:

at least one reaction chamber (1) having at least one inlet (7) and at least one outlet (10, 15) for passing therethrough a bulk material from top to bottom countercurrently to a gas,
at least one flow baffle (9) through which the gas is conducted from the bottom toward the top into the bulk material in the reaction chamber (1),
at least one first sliding surface (4') for the bulk material, being arranged above the reaction chamber (1) and supplying the inlet (7) of the reaction chamber (1) with bulk material, and
at least one second sliding surface (14) for the bulk material, arranged below the outlet (10, 15) of the reaction chamber (1),
wherein the sliding surfaces (4', 14) are inclined with respect to a horizontal axis of the reaction chamber (1) to such an extent that the bulk material is conveyed in a direction of inclination solely under action of gravity,
characterized int hat the first sliding surface (4') and the second sliding surface (14) are inclined in the same direction of inclination.
