A COKE DRY QUENCHING(CDQ) SYSTEM INCLUDING NEGATIVE PRESSURE IN COKE DISCHARGING ZONE ENABLING DRAGGING ATMOSPHERIC AIR INTO THE SYSTEM.

摘要

The present invention relates to a coke dry quenching (CDQ) system including negative pressure in coke discharging zone enabling dragging atmospheric air into the system through inspection hole/manhole of Vibrofeeder casing to change the gas flow current for hazardous gases in coke discharging zone to make it free from High Level of CO Gas as well as to remove deficiency of oxygen and a method of its implementation. The system comprises a negative pressure/suction line connected to slide gate cover or dust chute through ball valve and pressure gauge, to extract the hazardous gas from the point of source and maintaining selective negative pressure in relation to circulating quenching gas pressure/chamber pressure so that fresh atmospheric air is allowed to enter into the discharging zone through Vibrofeeder inspection hole/manhole to cool down the temperature inside discharge zone to safe working limit in a very short period of time to enable engineers/technicians to carryout maintenance.
