Cyclone Separator Layout for Compact Two-Stage Dust Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cyclone separating devices for air purification are bulky and have complex manufacturing processes due to their large radial dimensions and long gas passageways, making them impractical for many applications.
Innovation Solution
A compact cyclone separating device design featuring an upstream cyclone barrel with a downstream cyclone separating device mounted recumbently above it, forming a spatial angle between their axes, which reduces the overall height and radial dimensions by using multiple paratactic cyclone barrels and a filter mesh within the upstream barrel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two-leveled cyclone separating devices are adopted in series, then dust separation effectiveness is improved, but device size and radial dimension increase
Solution Approach 1:
The patent transitions from a horizontal arrangement of two cyclone separating devices to a vertical stacked arrangement. The downstream cyclone separating device is positioned above the upstream device, utilizing the vertical dimension to reduce the radial footprint. This dimensional change allows effective two-stage dust separation while maintaining a compact radial profile suitable for space-constrained applications.
Solution Approach 2:
The downstream cyclone separating device is partially mounted inside the upstream cyclone separating device, creating a nested configuration. The downstream device's cyclone barrel is positioned within the spatial envelope of the upstream device, with the gas passage extending downward to connect the two stages. This nesting approach maximizes space utilization and reduces overall device size.
2Reliability
If two-leveled cyclone separating devices are adopted in series, then dust separation effectiveness is improved, but manufacturing complexity increases
Solution Approach 1:
The patent merges the downstream cyclone separating device with the upstream device by positioning it above and connecting them through a shared gas passage structure. The gas passage extends from the bottom of the downstream device to the top of the upstream device, creating an integrated two-stage separation system. This merging reduces the number of separate components and simplifies manufacturing compared to completely independent devices.
3Area of stationary object
If downstream separating device is mounted inside upstream separating device, then radial dimension is reduced, but device height increases
Solution Approach 1:
The patent accepts the vertical stacking arrangement where the downstream device is positioned above the upstream device, which inherently increases height compared to a purely horizontal arrangement. However, this vertical configuration dramatically reduces radial dimension, making the device suitable for applications where horizontal space is more constrained than vertical space.
4Reliability
If long gas passageway is used between two cyclone separating devices, then serial separation is achieved, but production cost increases
Solution Approach 1:
The gas passage is integrated into the nested structure, extending from the bottom of the downstream cyclone separating device downward to connect with the top of the upstream device. This integrated passage design reduces the total length of gas passageway compared to separate devices with long external connections, thereby reducing manufacturing cost while maintaining serial separation capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design results in a smaller, more compact device with reduced height and radial dimensions, simplifying manufacturing and reducing production costs while maintaining effective air purification capabilities.
Implementation Method 1
Cyclone separating devices can be used to separate dust and other dirt from airflow by virtue of the centrifugal force produced by a highly revolving flow in the cyclone barrel
