Device for measuring Bu4N + ions in biomass fiber regeneration coagulating bath

The utility model discloses a device for measuring Bu4N + ions in a biomass fiber regeneration coagulating bath, and relates to the technical field related to biomass engineering. The device comprises a top plate, a bottom supporting disc, a reaction cylinder and measuring cylinders, the bottom supporting disc is arranged below the top plate, the reaction cylinder is arranged above the bottom supporting disc, the middle of the peripheral side of the reaction cylinder is fixedly communicated with a conveying pipe, the three measuring cylinders are arranged at the top of the top plate, and liquid level scales are printed on the peripheral sides of the measuring cylinders. By arranging the top plate, the bottom supporting disc, the reaction cylinder and the measuring cylinder, the problems that the time for obtaining a result is long when the concentration of Bu4N < + > ions in the biomass fiber regeneration coagulating bath is measured, and the steps for measuring the volume and the mass are more when the densi
