1. Background of alumina red mud treatment
Red mud is the main solid waste generated after extracting alumina from Bayer process in alumina production. Due to its high alkali content, fine particles, and high viscosity, dehydration is difficult. If the water content of red mud is too high, it will affect the subsequent stacking, transportation and resource utilization, therefore,efficient solid-liquid separation equipment and suitable industrial filter clothare crucial for the treatment of alumina red mud.
2. Application of rotary drum filter in red mud dehydration
Rotary drum filteris a vacuum filtration equipment widely used in the alumina industry for red mud dehydration. Its main features include:
- Continuous operation, improved efficiency:Rotary drum filters use multiple rotating filter disks to continuously perform solid-liquid separation, suitable for large-scale red mud treatment.
- Vacuum adsorption, efficient dehydration:Through vacuum negative pressure, the slurry on the filter cloth is quickly dehydrated to form a filter cake with high solid content.
- Small footprint, large processing capacity:Compared with other filtration equipment, the rotary drum filter has a compact structure and can process a large amount of red mud in a limited space.
- Automated operation, reduced labor costs:Automatic feeding, filtration, discharging and filter cloth cleaning can be realized to improve production efficiency.
3. The key role of industrial filter cloth in red mud treatment of rotary drum filter
The filter cloth is the core component of the rotary drum filter, which directly determines the filtration effect, filter cake quality and the stability of equipment operation. In the red mud filtration process, the filter cloth needs to have the following characteristics:
- Alkali resistance:Red mud contains a high concentration ofNaOH(sodium hydroxide), the filter cloth must have good alkali resistance to prolong its service life.
- High strength and wear resistance:In the continuous operation of the rotary drum filter, the filter cloth will withstand long-term mechanical friction and tension, so the filter cloth should have excellent wear resistance and tensile strength to prevent damage and deformation.
- Excellent air permeability and filtration accuracy:The filter cloth needs to ensure the retention rate of solid particles while ensuring efficient dehydration to prevent excessive solid content in the filtrate.
- Good filter cake release:Red mud particles are fine and easy to adhere to the surface of the filter cloth. High-quality filter cloth should have good filter cake release performance to improve equipment operation efficiency and reduce filter cloth clogging and frequent cleaning.
