Description:
The invention relates to a wood pulp acetification performance evaluation device, comprising a reaction tube and a stirrer, wherein the stirrer is installed at the upper end of the reaction tube by means of a sealing seat; a sealing gasket is arranged between the sealing seat and a stirring shaft; a water bath is arranged at the periphery of the reaction tube; a blow-off valve and a filter basket are sequentially arranged at the bottom end of the reaction tube from top to bottom. The temperature in the water bath is controlled, wood pulp and other needed raw materials are added into the reaction tube according to the needed proportion and sequential order, and a stirrer is started, so that the wood pulp and acetic acid are subjected to a reaction under the condition of stirring; after the reaction is finished, the reaction liquid is filtered by using the filter basket; a few pulp lumps exist in the filter basket, and filtrate is discharged outside through a liquid discharge nozzle; if the weight of filtrate i
