Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional compressed air purification systems face inefficiencies in separating moisture and minute foreign substances due to weakened centrifugal force as compressed air flows through multiple swirl chambers, leading to decreased separation efficiency and potential blockages in filter elements.
Innovation Solution
A compressed air purification apparatus utilizing a double cyclone system, where compressed air is swirled twice, with the outer drum generating an initial cyclone and the inner drum generating a secondary cyclone, enhancing centrifugal force and separating efficiency without the need for filter elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter element with minute pores is used to remove moisture from compressed air, then the purification effectiveness is improved, but the filter element becomes blocked over time, increasing pressure loss and requiring frequent replacement
Solution Approach 1:
The patent extracts the harmful function of filter elements by completely removing them from the system. Instead of using porous filters that block over time, the invention uses a cyclone separator that continuously separates moisture through centrifugal force without any filtering medium, thereby eliminating pressure loss and the need for replacement.
Solution Approach 2:
The patent replaces the mechanical filtration system (filter elements with pores) with a centrifugal separation system (cyclone generator). This substitution uses rotational mechanics to generate centrifugal force that separates moisture from compressed air, avoiding the blockage issues inherent in porous filter systems.
2Manufacturing precision
If multiple swirl chambers are used to separate minute foreign substances, then the separation efficiency for fine particles is improved, but the centrifugal force weakens as air flows through successive chambers, decreasing overall separation performance
Solution Approach 1:
The patent employs a nested structure where an inner cyclone generator is placed inside an outer cyclone generator. The compressed air undergoes first cyclonic separation in the outer generator, then enters the inner generator for a second cyclonic separation. This nested arrangement allows sequential separation with enhanced centrifugal force in the inner chamber, effectively removing both large and minute foreign substances while maintaining high separation efficiency.
3Reliability
If filter elements with finer pores are used to achieve higher purity levels, then the compressed air purity is improved, but the blockage occurs more significantly, reducing operational lifespan
Solution Approach 1:
The patent removes the filter element entirely from the system, replacing it with a cyclone separator that achieves high purity through centrifugal separation without any porous medium. This extraction eliminates the blockage problem that limits the operational lifespan of fine-pore filters, allowing continuous operation without replacement.
4Ease of operation
If pressure gauges are installed to monitor filter element blockage, then the timing for replacement can be determined, but the equipment cost, installation space, and maintenance cost increase
Solution Approach 1:
The patent extracts and removes the filter element that requires monitoring, replacing it with a cyclone separator system that has no consumable parts needing replacement. This eliminates the need for pressure gauges and monitoring systems, thereby reducing equipment cost, installation space, and maintenance requirements while ensuring continuous operation.

AI summary
A compressed air purification apparatus includes a cover, an outer drum configured such that compressed air supplied through the inlet swirls downwards between the cover and the outer drum, a discharge pipe inserted into the insertion port to couple the outer drum to the cover, an inner drum configured such that the downwardly swirling compressed air flows upwards between the outer drum and the inner drum and again swirls downwards between the discharge pipe and the inner drum, a collector drum formed in an integrated manner with the inner drum, and a drain cover configured such that impurities separated from the compressed air are collected therein. The compressed air can separate water, oil and minute foreign substances from compressed air by rotating compressed air two times in a double cyclone.
