Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The particle collection efficiency of conventional cyclone dust collectors is not high enough, as the water mist and paint mist particles do not mix sufficiently, leading to lower collection efficiency.
Innovation Solution
A cyclone dust collector with a spiral flow path and a constricted part forming member that includes triangular ribs and nozzles to spray water mist radially at a constricted area, enhancing the mixing of water mist and paint mist particles, thereby improving collection efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If water mist is sprayed in conventional locations without constricted part, then the structure is simple, but the mixing between water mist and paint mist particles is insufficient leading to low collection efficiency
Solution Approach 1:
The cylindrical case is divided into multiple sections along the spiral flow path, with constricted parts formed at specific locations. These segmented constricted parts create localized turbulence zones that enhance mixing between water mist and paint mist particles, thereby improving collection efficiency without requiring complete restructuring of the entire device.
Solution Approach 2:
Water mist is sprayed at predetermined locations upstream of the constricted parts, allowing the water mist to mix with paint mist particles before they enter the high-turbulence constricted zones. This preliminary action ensures that particles are pre-coated with water mist, facilitating more effective collection in the subsequent constricted parts.
2Productivity
If multiple nozzles are added at various locations to improve mixing, then collection efficiency improves, but the device complexity and manufacturing cost increase
Solution Approach 1:
Instead of uniformly distributing nozzles throughout the cyclone dust collector, the invention concentrates nozzle placement at specific locations upstream of constricted parts. This localized approach creates high-mixing zones precisely where needed, achieving effective particle collection with fewer nozzles and simpler manufacturing requirements.
Solution Approach 2:
The constricted parts act as intermediary structures that amplify the mixing effect. By introducing these geometric features into the flow path, the system achieves enhanced mixing with a single nozzle per constricted part, rather than requiring multiple nozzles distributed throughout the entire device.
3Productivity
If the spiral flow path is made narrower to increase turbulence and mixing, then collection efficiency improves, but the flow resistance increases and productivity may decrease
Solution Approach 1:
Rather than narrowing the entire spiral flow path, the invention applies localized constriction only at specific sections where turbulence enhancement is most beneficial for mixing. This partial action approach maintains adequate flow capacity in non-constricted sections, minimizing overall flow resistance while achieving sufficient turbulence for effective particle collection.
Solution Approach 2:
The constricted parts are positioned at specific angular and axial locations within the spiral flow path, creating three-dimensional turbulence zones. This spatial arrangement allows the system to generate intense local mixing without uniformly reducing the flow cross-section, thereby maintaining acceptable flow resistance levels.

AI summary
Provided is a cyclone dust collector with a higher particle collection efficiency than before. The cyclone dust collector includes an inner wall being arranged on an edge portion of a first cross section defined by a plane containing a center axis of the cylindrical case and part of the spiral flow path intersecting with each other and being adapted to make the part of the flow path narrower and a first nozzle that sprays the water mist toward the air passing through a constricted part being part of the spiral flow path made narrower by the inner wall.
