1. When designing titanium rod filters, particularly for solid-liquid separation applications like carbon filtration, the use of 20-inch filter elements is generally avoided. This is because the length of a 20-inch filter element, typically around 500-600mm, combined with the filter cylinder's length, results in a height of about 1 meter for lifting the filter element. This height is not conducive to user-friendly operation. Additionally, titanium rod filter elements, being sintered from titanium powder at high temperatures, are relatively brittle. During installation and removal, there is a risk of accidental contact with the inner and outer walls of the cylinder, as well as the titanium rods themselves, potentially causing cracks or damage.
2. When determining the depth of the titanium rod filter cartridge, it is important to consider the actual amount of activated carbon or other filter media being used and allow enough space for proper filtration. Insufficient space can lead to clogging of the titanium rod filter, increased pressure differential, decreased flow rate, and potential energy loss.
3. It is advisable to design a thicker perforated plate for lifting the filter element. This is not only to account for the weight of the titanium rods but also to accommodate the entry of solid particles, such as activated carbon or sludge. If these particles adhere to the titanium rods, it can block the surface of the filter element, increase pressure differential, affect filtration efficiency, and potentially cause deformation or collision of the filter elements.
4. To prevent direct impact on the filter element and avoid loosening or collisions between filter elements, it is recommended to include a baffle at the inlet of the filter design.
5. The design of the titanium rod filter should consider factors such as potential bumps and impacts. Installing additional supports around the perimeter of the titanium rod filter, slightly longer than the filter itself, can effectively protect against bumps during handling, loading, and unloading, preventing invisible damage to the titanium rod elements.
6. During installation and use of titanium rod filters, it is crucial to ensure careful cleaning of the titanium rods before installation. Thoroughly inspect the filter elements for completeness, cracks, or damage. A simple method is to pass compressed air through the interior of the titanium rods and then immerse them in water to check for cracks. Once confirmed to be in good condition, the titanium rod filter elements can be mounted on the perforated plate. When tightening the nut, apply moderate force with a wrench. Over-tightening can lead to breakage or concealed damage, while insufficient tightening may cause carbon leakage.
