Coke dry quenching apparatus

Abstract

A coke dry quenching apparatus comprises a vertical chamber in the lower portion of which is disposed a quenching gas feeding means. The chamber has in its roof a charging hole and in its bottom a discharging gate. In the walls of the chamber is disposed a plurality of peripheral gas conduits communicated with the inner space of the chamber and with an annular collector having a common gas withdrawal conduit. According to the invention the hollow of the collector is divided by a horizontal partition provided with ports into two cavities communicating with one another, the lower cavity being communicated with the peripheral gas conduits and the upper one with the common gas withdrawal conduit. Due to the fact that the pressure of quenching gas in the lower cavity of the collector is equalized, the proposed apparatus ensures that the quenching gas flow rate through all the peripheral gas withdrawal conduits is practically equal, which provides for a uniform cooling of the whole mass of the coke being treated. This permits the consumption of quenching gas to be reduced, and the efficiency of the process to be raised.
