Description

Technical Field

[0001] The utility model relates to the technical field of graphitization furnace condensation equipment, in particular to a condensation device of a graphitization furnace. Background Art

[0002] The design of the condensation and filtration system of the traditional graphitization furnace is relatively simple. Its main purpose is to cool the extracted high-temperature gas. However, during the condensation process, the extracted high-temperature gas contains a large amount of volatiles. These volatiles will condense and deposit in the tubes of the condensation device in a slurry state, causing the tubes to be blocked and making it impossible for the vacuum system to maintain an extremely low vacuum degree. Therefore, it is necessary to clean the tubes in the condensation device after each production operation. Due to the design structure, cleaning is difficult and the sealing cover must be frequently removed. Utility Model Content
