Flame path partitioning structure between oven chambers of open type anode roasting oven

Abstract

The invention discloses a flame path partitioning structure, in particular to a flame path partitioning structure between oven chambers of an open type anode roasting oven in the production field of carbon for aluminum. The flame path partitioning structure comprises an oven chamber flame path inside a system, an oven chamber flame path outside the system and a crosswall, wherein flame through holes are arranged among the crosswall, the oven chamber flame path inside the system and the oven chamber flame path outside the system, flame path partition plates in the fire through holes are inserted to U-shaped sealing grooves at the bottoms and the two sides of the flame through holes, slot bricks fixed on the crosswall are arranged above the flame through holes, oven surface slot building blocks are arranged above the slot bricks, the upper parts of the flame path partition plates pass through the slots of the slot bricks and are arranged in the slots of the oven surface slot building blocks, and partition covers are arranged above the flame path partition plates. The flame path partitioning structure improves the partition action between the corresponding oven chamber flame paths inside and outside the system, enhances the sealing performance of the oven, effectively reduces the suction volume of cold air outside the system, can keep the sealing performance for a long term, has simple structure and is easy to implement.

Description

technical field [0001] The invention relates to a fire passage barrier structure, in particular to a fire passage gate partition structure between furnace chambers of an open anode roasting furnace in the field of aluminum carbon production. Background technique [0002] Anode roasting furnace will produce a large amount of flue gas during the production process of anode roasting. In order to discharge these flue gases, the anode roaster needs to be equipped with an annular flue outside the furnace body, and a smoke exhaust fan is installed at the general outlet of the annular flue to provide the required negative pressure for the exhaust of the flue gas. On the smoke exhaust hole of the last low-temperature furnace chamber of the flame system running in the anode roaster, a special smoke exhaust device is provided to connect the furnace fire channel with the ring-shaped main flue, and at the same time, the flue damper is used to prevent the smoke from entering the flame sys...
