Vertical Wires: Diameter 3-6 mm, Tensile Strength 400-1200 MPa

Component Specifications

Definition

Vertical wires are critical structural components in filter bag cages used in dust collection and air filtration systems. These wires run parallel to the filter bag's length, providing axial support to maintain the bag's cylindrical shape under varying pressure differentials. They prevent bag collapse, ensure uniform dust cake distribution, and optimize filtration efficiency by maintaining consistent surface area exposure. Typically arranged in a circular pattern around the cage's circumference, they work in conjunction with horizontal support rings to create a rigid framework that withstands mechanical stress during pulse-jet cleaning cycles.

Working Principle

Vertical wires function as tensile support members that resist compressive forces during filtration operations. When dirty air flows through the filter bag, pressure differentials create inward forces that could collapse the bag. The vertical wires counteract these forces through their inherent stiffness and tensile strength, maintaining the bag's open cross-sectional area. During cleaning cycles, they provide structural integrity as the bag flexes during reverse air or pulse-jet cleaning, ensuring the dust cake is properly dislodged without damaging the filter media.

Frequently Asked Questions

What happens if vertical wires fail in a filter bag cage?

Wire failure causes bag collapse, reducing filtration area, increasing pressure drop, allowing dust bypass, and potentially damaging the filter media through abrasion or improper cleaning.

Can vertical wires be replaced individually?

Typically no - vertical wires are welded or mechanically fastened to end plates and rings. Damaged wires usually require complete cage replacement or professional re-welding to maintain structural integrity.

How do I select the right vertical wire material?

Consider gas temperature, chemical composition, moisture content, and abrasiveness. Stainless steel for corrosive environments, carbon steel for dry applications, and coated wires for moderate corrosion resistance.
