Comparison with Fully Enclosed Plate Filter (Vertical Leaf Filter)
Filter Element Form
Full Enclosed Plate Type (Vertical Blade Filtration)
Operating Mode: Automation Level
Fully automatic operation with low manual labor.
Vertical Leaf Filter: Falls between plate and frame and candle filters in terms of automation.
Filter Element Form
6+1-style integrated petal structure, with a filtration pressure regulation device to ensure strong filtration element, high flux, uniform filter cake, and stable filtration efficiency. Filtration elements are available in various materials, both metallic and non-metallic, offering corrosion resistance and long service life, reducing the cost of spare parts.
Rectangular metal mesh support structures make filter cloth installation complicated and equipment maintenance difficult, and the plate-like support structure leads to uneven pre-coating, affecting filtration performance.
Uniformity of Pre-coating:
Single filter elements have a smaller area, with a cylindrical and radial structure. The filtration pressure regulation device ensures a very uniform pre-coating.
Single blade filters have a larger area with a rectangular plate-like structure. The lack of flow rate adjustment devices results in uneven pre-coating.
Filter Cloth Attachment to Support:
Special tightening mechanisms at both ends ensure no leakage and facilitate easy installation and disassembly.
In contrast, installation and disassembly are inconvenient in the case of the other filter type, which can lead to potential leakage issues.
Filter Cloth Regeneration:
The filter cloth can be regenerated using various solutions such as gas, clean water, acid, or alkali through methods like backwashing, forward washing, or scrubbing, depending on the requirements. After regeneration, the flux remains unaffected, and the frequency of filter cloth replacement is low.
In contrast, for vibrating-cake filter cloth regeneration, it can be backwashed with gas or cleaning liquid, but it lacks a filter element pressure regulation system. This can lead to gas short-circuiting, less effective backwashing, increased complexity in cleaning, and an intermediate filter cloth regeneration effect, resulting in a higher frequency of filter cloth replacement compared to plate and frame and candle filters.
The filter elements come in various specifications, such as 1.6M, 2M, 2.5M, 2.7M, etc. They offer a high number of filter cores per unit volume, resulting in a large filtration area. This, in turn, leads to long filtration cycles. After the filtration cycle, the discharge and cleaning processes are relatively short, allowing for a quick transition to the next filtration cycle. This design contributes to high production efficiency.
In contrast, the blade-supported mesh plates have larger individual areas but a lower quantity of filter elements, resulting in a smaller filtration area. After the filtration cycle, discharging and cleaning processes take longer, and the production efficiency falls between that of plate and frame filters and candle filters.
