Abstract

The invention relates to the technical field of graphite preparation, in particular relates to a binary graphitization furnace which is combined by adopting a parallel connection way. The binary graphitization furnace comprises a first furnace body (1) and a second furnace body (2), wherein a middle combination part of the first furnace body (1) and the second furnace body (2) forms waste heat flue space (3); a circulating tube is arranged in the waste heat flue space; the circulating pipe enters the waste heat flue space (3) from an inlet (4) formed in the front surface of the middle combination part and stretches out of the waste heat flue space (3) from an outlet (5) formed in the front surface of the middle combination part; an axial flow fan is arranged at the position of the outlet of the waste heat flue space (3). The binary graphitization furnace disclosed by the invention is reasonable in design; compared with an existing graphitization furnace kiln, the actual effects of high heat efficiency, good safety, capability of implementing forced cooling and the like are obtained; meanwhile, the binary graphitization furnace is clear in structure and energy-saving purpose, has very good practical performances of safety, easiness in operation and the like and has very obvious economic benefit after implementation.

Description

technical field [0001] The present invention designs the technical field of graphite preparation, specifically a two-body graphitization furnace combined in parallel. Background technique [0002] Traditional high-temperature ventilated graphitization furnaces (referred to as Acheson graphitization furnaces) all adopt the single furnace method. This design method has better flexibility, and the production is easy to deploy and control. [0003] The general process route of the graphitization kiln is: pre-loading operations (canning, kiln maintenance, laying ventilation pipes, filling the bottom of the furnace, etc.) ---- Furnace loading ---- Power transmission (ventilation) ---- Overall cooling----out of the oven----finished product cooling----packing. [0004] However, the monomer graphitization furnace has the following problems: [0005] 1. Due to the large power consumption and large heat loss of the single graphitization furnace, the energy utilization rate is low an...
