Description about pulp bleaching tower:
The tower with a cylindrical structure, the lower portion of the tower body is a certain angle of the vertebral bottom of a feed screw apparatus, because the slurry under gravity always having drawn movement trend, so spiral very short transport length design can do to put the pulp, which significantly reduces power consumption, but the rate of decline of the tower slurry uniform, to ensure that the bleaching effect.
The pyramidal structure for the bleaching equipment effectively prevents pulp from blocking. Additionally, the special internal structure ensures the uniformly pulp dropping, which result in consistent bleaching time. There is special device designed at the bottom of the high concentration bleaching tower to dilute the pulp, which simplifies the manufacturing process, accordingly.
Functions and features:
1. The tower is used for high consistency hydrogen peroxide bleaching of ground wood pulp or other kinds of pulp.
2. Special inner structure ensures pulp fall uniformly. It unifies pulp falling time and bleaching time.
3. Dilution function at the bottom helps in bleaching in high consistency and pulp flowing in low consistency. It makes the process of stock preparation simpler.
