Product Description
The Distributor for headbox top is also a kind of slurry distribution element with dual functions of slurry distribution and rectification. It is composed of many graded and expanded flow channels. Due to the graded expansion, the paper flow in it also diffuses step by step. At this time, there is a large velocity difference between the flow beam with high central velocity and the fluid flowing at low speed due to the diffusion and friction with the pipe wall around it, resulting in high shear force and high intensity micro turbulence.
At the same time, the shape of each section in the flow channel is different. When entering from one section to another, the flow beam will change direction, rearrange, and also produce strong small vortex.
Due to the consumption effect of diffusion and the homogenization effect caused by the redistribution of velocity head, the slurry at the outlet forms a good dispersion state, which is a good slurry distribution and rectification element. Because of this dual function, the headbox using this kind of slurry distribution element can be greatly simplified.
Advantages
1. Compared with other uniform pieces, it can make the pulp flow evenly distributed along the width of the paper machine.
2. Micro-turbulence is generated to disperse the fiber network and flocs, providing favorable conditions for paper web forming.
3. It is unnecessary to set other uniform parts, and other unnecessary parts are omitted, so that the headbox structure is simple.
