Volatile communication structure for end furnace chambers of carbon secondary roasting furnace

Abstract

The invention discloses a volatile communication structure for end furnace chambers of a carbon secondary roasting furnace. The structure comprises the carbon secondary roasting furnace; both ends of the carbon secondary roasting furnace are provided with a volatile communication device; and ends of various bins of the end furnace chambers are provided with bin volatile passageways, and volatile passageway branch pipes used for connecting the volatile communication device and the bin volatile passageways. The structure has the advantages that the structure can make volatile produced in the bins of a downstream furnace chamber collected into the volatile communication device under the condition of basically same negative pressure and resistance. The condensation phenomenon of the volatile cannot appear in a pipeline, and the smoothness of the flow of the volatile is ensured during the operation across the central line of the furnace. The temperature of the furnace chambers and the binsin a flame system has even distribution, which is favorable for improving the quality of secondary roasting. The structure effectively avoids the pressure jump in the related bins, and is favorable for guaranteeing the personal safety of operation personnel.

Description

technical field [0001] The invention relates to a carbon secondary roasting furnace in the field of graphite electrode production, in particular to a volatile component communication structure in a furnace chamber at the end of the carbon secondary roasting furnace. Background technique [0002] When the flame system of the carbon secondary roaster runs to one end of the furnace and needs to be operated across the center line of the furnace, in addition to the flue gas flow in the system must be turned 180° through the connecting fire channel, the volatile flow direction must also be changed accordingly , to ensure that a large amount of volatile matter produced by the secondary roasting can smoothly enter the fire channel of the high-temperature furnace chamber for combustion. [0003] In the existing carbon secondary roasting furnace, the volatile matter flows across the center line of the furnace. Generally, a special channel with a cut-off valve is used in the end furnac...
