Rapid cellulose wetting equipment and rapid cellulose wetting process

Abstract

The invention discloses rapid cellulose wetting equipment and a rapid cellulose wetting process. The equipment comprises a material bin, a pre-mixer, a high-speed continuous mixer, cellulose, an organic solvent, a pipeline and a control system, wherein the material bin is arranged on the upper end of the pre-mixer, the material bin, the pre-mixer and the high-speed continuous mixer form one connection, the material bin, the pre-mixer and the high-speed continuous mixer are respectively provided with a plurality of solvent inlets, the solvent inlet is provided with a spraying nozzle, and one end of the spraying nozzle is connected to the pipeline. According to the present invention, the organic solvent is gradually sprayed onto cellulose through the spraying nozzles, such that the cellulosecan be fully infiltrated, the wetting quality is improved, the continuity of cellulose wetting is achieved, the production efficiency is greatly improved, the precise control of the solvent consumption is achieved, and the use cost is reduced.

Description

technical field [0001] The invention relates to a cellulose fast wetting equipment and a wetting process. Background technique [0002] The existing production equipment and technology are to put cellulose into a stirring tank filled with organic solvent for stirring, so that the two are fully contacted and wetted to carry out the next step of reaction. Due to the small specific gravity of cellulose, it floats on the surface of the solvent and cannot fully contact with the solvent, so that the infiltration is not smooth, and it is prone to agglomeration and incomplete infiltration during the infiltration; the inconsistency of cellulose infiltration time will lead to uneven reaction of the product. The same, affect the quality, in addition there are problems such as long stirring time, low production efficiency, and inability to continue production; at the same time, problems such as large amount of solvent addition, low utilization rate, and need for follow-up recovery treat...

Problems solved by technology

Due to the small specific gravity of cellulose, it floats on the surface of the solvent and cannot fully contact with the solvent, so that the infiltration is not smooth, and it is prone to agglomeration and incomplete infiltration during the infiltration; the inconsistency of cellulose infiltration time will lead to uneven reaction of the product. The same, affect the quality, in addition there are problems such as long stirring time, low production efficiency, and inability to continue production; at the same time, problems such as large amount of solvent addition, low utilization rate, and need for follow-up recovery treatment are generated, resulting in an increase in production costs.
