Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dust and particulate separation systems for air streams in the food industry require extensive ductwork and pose explosion hazards, necessitating placement outside and increasing maintenance risks.
Innovation Solution
An air-particle separation system that operates as a 'wet system' with a misting module, screen basket, and suction fan, which can be located next to dust-producing equipment, minimizing explosion hazards and maintenance needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional dust separation systems (bag houses, cyclones, large blowers) are used, then dust particles can be removed from air streams, but the systems require extensive ductwork, create pressure drop, and pose explosion hazards
Solution Approach 1:
The patent extracts the dust separation function from the conventional complex system and implements it in a simple, compact wet system that can be placed directly next to the dust-generating equipment, eliminating the need for extensive ductwork and reducing explosion hazards
Solution Approach 2:
The patent introduces water as an intermediary substance that captures dust particles through wetting and adhesion mechanisms, replacing the need for complex mechanical separation systems and extensive ductwork
2Reliability
If conventional dust separation systems are placed outside to avoid explosion hazards, then safety is improved, but the distance from dust-producing equipment increases, requiring extensive ductwork and creating pressure drop
Solution Approach 1:
The patent removes the dust separation function from remote locations and integrates it directly at the dust source through a compact wet system, eliminating the energy loss associated with long ductwork while maintaining safety through the simplified design
Solution Approach 2:
The patent uses hydraulic principles with water to capture dust particles directly at the source, eliminating the need for long pneumatic ductwork and reducing pressure drop while maintaining explosion safety through the wet system design
3Reliability
If conventional dust separation systems are used, then dust particles can be removed from air streams, but the systems require intensive maintenance and pose maintenance risks
Solution Approach 1:
The patent extracts the dust removal function into a simple wet system with minimal moving parts, eliminating the need for intensive maintenance of complex components while maintaining effective dust particle removal
Solution Approach 2:
The patent employs a simple screen basket and water system that can be easily cleaned and maintained, replacing expensive and complex maintenance requirements of conventional systems with a simpler, more maintainable design

AI summary
The air-particle separation system is a dust handler that includes a main body with a misting module mounted thereon. The misting module includes air input pipes for receiving air with particles and a misting nozzle for soaking the particles within the air stream. The water particles and air are directed downwardly into a screen basket that is supported in a first chamber. A screen purging nozzle removes any particles stuck to the screen. Air is pulled through the system by a suction fan. An optional high-pressure fan may also be provided. The water, the water-soaked particles, and the air exit the screen basket and enter the first chamber and a second chamber. Air is removed from the chambers through the fan(s), while a drain in the bottom of the chambers drains the water and particles.
