Title:
DEVICE FOR BRINGING SOLID SUBSTANCE AND GAS INTO CONTACT
Document Type and Number:
Japanese Patent JPS6351933
Kind Code:
A
Abstract:
An apparatus for contacting solids with gases, preferably a needle coke preheater, which includes an elongated housing (12) having an entrance and an exit and means for introducing solids into the entrance of the housing. A bed support (16) divides the housing into an upper chamber (30) and a lower chamber (28) and is declined from the horizontal at an angle such that the solids introduced into the entrance of the housing slide down the bed support toward the exit of the housing. The bed support contains a plurality of openings distributed between two solid rectangular borders which serve as the two long parallel sides of the bed support. The openings are sufficienlty large so that gases can flow from the lower chamber in contact with the solids and then into the upper chamber. The solid rectangular borders prevent preferential flow of the gases up the walls of the housing by forcing the gases to flow toward the center of the bed support. The apparatus also contains means for introducing gases into the lower chamber of the housing, means for removing gases from the upper chamber of the housing and means for removing solids from the exit of the housing.
