Abstract

The invention belongs to the technical field of bamboo pulp fiber processing, in particular to a bleaching system for bamboo pulp fiber processing treatment. Aiming at the problem that a bleaching device for bamboo pulp fibers in the prior art will reduce the grouted fiber strength to affect the actual using effect, the invention provides a scheme as follows: the bleaching system comprises a bleaching box, wherein a cover plate is hermetically arranged at the top end of the bleaching box, a liquid injection pipe and a liquid drain pipe are separately connected to the top end and the bottom endof the outer wall of the bleaching box, a horizontally placed communicating pipe is rotatably connected to the bottom between the outer walls on two sides of the bleaching box, the communicating pipeis located above the liquid drain pipe, and a gas injection pipe and an air blowing pipe are separately fixed to positions, corresponding to the communicating pipe, of the outer walls on two sides ofthe bleaching box. As a bleaching agent is used to be reacted with a bamboo pulp fiber solution in the communicating pipe, so that a liquid flow in the communicating pipe exchanges in a reciprocatingmanner. A top solution is in a low-temperature environment by means of circulating cold air in a cooling cylinder in the middle position of the top, so that excessive damage to the bamboo pulp fibersis avoided.

Description

technical field [0001] The invention relates to the technical field of bamboo pulp fiber processing, in particular to a bleaching system for bamboo pulp fiber processing. Background technique [0002] It is well known that bamboo is widely used, but it has been used in textiles in recent years. It is called bamboo fiber. Bamboo pulp fiber is a kind of pulp made of bamboo chips, and then made into pulp and then wet spinning Fiber-forming, its production process is basically similar to that of viscose. In the process of making bamboo fiber, the bamboo raw material will be dissolved to make grout, and the bamboo pulp fiber needs to be bleached. [0003] Nowadays, when bleaching bamboo pulp fibers, ECF three-stage bleaching technology is generally used to inject corresponding chlorine dioxide gas and solid bleaching agent into the grouting solution for bleaching operation, but often in the grouting solution during the bleaching process The reaction is violent and the temperatur...
