Cyclone Dust Collector Nozzle Layout for Better Mist-Particle Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The particle collection efficiency of conventional cyclone dust collectors is not high enough due to inadequate mixing of paint mist particles with water mist, resulting in lower collection rates.
Innovation Solution
A cyclone dust collector design featuring a spiral flow path with a constricted part forming member and a nozzle assembly arranged within a vertical cross section, which enhances the mixing of water mist with air-borne particles by creating turbulence and ensuring even distribution of water mist along the spiral flow path, thereby improving particle collection efficiency.

Engineering Contradiction Analysis
1Productivity
If spray nozzles are dispersedly arranged in a regular pattern along a spiral flow path, then the device structure is simple, but the particle collection efficiency is not high enough
Solution Approach 1:
The nozzle assembly divides the vertical cross section into multiple regions (first, second, third, and fourth split regions) with nozzles arranged in each region. This segmentation allows water mist to be sprayed at multiple locations simultaneously, improving particle collection efficiency by ensuring comprehensive coverage of the spiral flow path without requiring a single complex nozzle system.
Solution Approach 2:
Different nozzle groups are positioned in different vertical cross-section regions to provide localized water mist spraying. The first and second nozzle groups spray in a first direction while the third and fourth nozzle groups spray in a second direction, creating locally optimized mist distribution patterns that enhance particle collection efficiency in specific areas of the spiral flow path.
2Productivity
If nozzles spray water mist in a single direction, then the nozzle structure is simple, but the mixing of paint mist particles with water mist is inadequate
Solution Approach 1:
The nozzle assembly employs asymmetric spray directions with different nozzle groups oriented at different angles. The first and second nozzle groups spray water mist in a first direction while the third and fourth nozzle groups spray in a second direction, creating asymmetric mist distribution patterns that enhance turbulence and mixing of paint mist particles with water mist throughout the spiral flow path.
Solution Approach 2:
The nozzle assembly adds directional diversity by spraying water mist in multiple directions (first direction and second direction) rather than a single direction. This multi-dimensional spray approach creates more thorough mixing of particles with water mist by introducing turbulence from multiple angular perspectives within the spiral flow path.
