Wet-Flow Dust Extraction Tower for Fibrous Dust Clogging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fibrous materials in dust tend to form entangled webs, plugging or clogging cyclones and other dust control components in air handling and cleaning systems, particularly in applications like metal recycling, tire shredding, agriculture, and wood processing.
Innovation Solution
A wet-flow dust extraction tower is integrated into the air handling system to collect and remove fibrous materials and fine particulates, using a cylindrical shell with water nozzles to wet the dust and fibers, a cone design for circulation, and a scalping box to capture the effluent, which is then dewatered and disposed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cyclones and baghouses are used to capture dust, then dust removal efficiency is improved, but fibrous materials form entangled webs that plug or clog the components
Solution Approach 1:
The wet-flow dust extraction tower is positioned upstream in the air handling system to remove fibrous materials before they reach the cyclones and baghouses. Water is sprayed onto the dust-laden air stream to wet and weigh down the fibers, preventing them from forming entangled webs that would clog downstream components.
Solution Approach 2:
Water acts as an intermediary substance between the fibrous dust and the downstream collection components. By introducing water into the air stream, the fibers are transformed from a dry, entanglement-prone state to a wet, manageable state that can be effectively removed without clogging the system.
2Object-generated harmful factors
If wet-flow dust extraction tower is added to remove fibrous materials, then clogging is prevented, but device complexity increases
Solution Approach 1:
The wet-flow dust extraction tower is designed as a separate, modular unit with distinct functional zones: an upper section for water distribution and a lower section for dust collection. This segmentation allows the system to handle wet dust effectively while maintaining simplicity in each individual component.
Solution Approach 2:
The problematic fibrous materials are extracted from the main air stream early in the process using the wet-flow extraction tower. By removing the fibrous component separately before it reaches the main dust collection system, the overall system complexity is reduced as the downstream components don't need to handle mixed dust types.
Applied Scientific Principles

Function Achieved in This Case
Effectively captures and removes fibrous materials and fine particulates, preventing clogging and ensuring clean air output, with the captured materials being treated and disposed of efficiently.
Implementation Method 1
A wet-flow dust extraction tower includes a cylindrical shell, with a tower inlet and a top outlet. The tower inlet is provided to receive and transport air comprising dust fines and fibers from the air handling components of an air handling and cleaning system, into the cylindrical shell.
Implementation Method 2
The cylindrical shell further includes a cone centrally positioned within the lower segment.
Implementation Method 3
secured on an interior lateral surface of and to the bottom surface of the lower segment may be a scalping box, with an open side in the flow path to capture wet dust fines and fibers as they circulate about the lower segment of the cylindrical shell
