▎ 摘　　要

NOVELTY - The tower has a vacuum pump is installed at one end of a vacuum bottom housing (12) through a mounting seat, and a fixing block (14) is provided on the top of the vacuum bottom housing. A limit slot (18) is embedded the bottom of the vacuum bottom housing, and a limit portion (17) is arranged in the limit slot. A hollow interlayer is arranged between a tower body (4) and a casing (7), and a cooling mesh plate (8) penetrates through the bottom end of the tower body. The two ends of the cooling screen are located in a hollow interlayer (10), and a limit screen frame (1) is installed in the tower body through bolts. The limit net frame is filled with graphene (6), and the inner upper end of the tower body is installed with an absorbent cotton block (5) through a connecting portion and a bolt. USE - Non-clogging degassing tower for production of acetylene gas for recovery of acetylene gas from calcium carbide slurry. ADVANTAGE - The non-blocking degassing tower used for the production of the calcium carbide slag slurry to recover the acetylene gas has various functions, simple operation, easy production, meets various needs in use, and is suitable for wide promotion and use. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the overall structure of a degassing tower that is not easy to be blocked for the production of acetylene gas recovered from calcium carbide slag slurry.
