Description

Technical Field

[0001] The utility model belongs to the technical field of papermaking, in particular to a detachable baffle group for a gas-liquid separation tank. Background Art

[0002] During paper machine production, a turbine vacuum pump creates a vacuum, extracting air from the pulp to remove moisture, thereby increasing the dryness and dehydrating the paper. The vacuum also serves to transfer the paper. The gas-liquid separator is a crucial protective device for the safe operation of the turbine machine. During the gas-liquid separation process, most of the pulp flows to the bottom of the separator along with the water. The filtrate is then discharged from the separator via a filtrate pump, but some pulp accumulates on the undercuts of the baffles. The baffle assembly requires regular cleaning to remove any accumulated pulp fibers on the undercuts to ensure effective separation.

[0003] At present, the gas-liquid separation tanks used in the industry all use fixed baffle groups, which cannot be disassembled and are difficult to clean. When the baffle group is not cleaned thoroughly, the separation effect will decrease, causing the turbine vacuum machine to suck the gas-liquid mixture containing pulp into the turbine vacuum machine. The turbine vacuum machine runs at a high speed and has extremely high balance requirements. When the turbine vacuum machine runs with liquid, it will cause the operating current of the turbine vacuum machine to increase, and may seriously cause overcurrent equipment to trip. In addition, long-term operation of the turbine vacuum machine with liquid will cause serious wear and cavitation to the impeller, causing serious damage to the equipment. For this reason, the present application proposes a detachable baffle group for a gas-liquid separation tank. Utility Model Content
