AI Technical Summary

Technical Problem

Existing gas solid contacting devices face issues with the accumulation of undesired particles, such as stones or off-specification particles, which disrupt the flow and residence time of particulate material, leading to non-uniform treated product properties and frequent maintenance needs.

Method used

Incorporating reject discharge openings in the gas distribution plate with larger dimensions than regular gas openings to selectively remove heavier and denser undesired particles, ensuring they are directed to a separate collection unit, thereby maintaining the flow and improving the operational uptime and uniformity of the treated particulate material.

Benefits of technology

Effectively removes undesired particles, preventing blockages and stream disruptions, enhancing the operational flexibility and uptime of the device while ensuring a uniform treated product quality.

Abstract

A device (10) for processing a flow of particulate material by contact with a gas flow comprises a housing (12) defining a processing chamber (18) and a plenum (20) arranged below the processing chamber (18) separated by a gas distribution plate (30), wherein the processing chamber (18) defines a contact path (22) for contact between the flow of particulate material and the gas flow, the contact path (22) comprising a plurality of sections, wherein sections (36;38'; 38''; 40) are separated from one another by a partition (34; 34'; 34'') provided with a transfer passage (48; 48'; 48''). The gas distribution plate (30) is provided with gas openings (32) configured to allow passage of the gas flow from the plenum (20) to the processing chamber (18) to establish a displacement of particulate biomass material in a displacement direction along the contact path (22). The gas distribution plate (30) comprises at least one reject discharge opening (60) configured for allowing passage of particulates to a discharge unit (64) and having a size larger than the gas openings (32).
