Solution Overview

Problem

Existing airborne dust collection systems are costly, difficult to transport, and pose risks during servicing due to fixed installations and hazardous dust handling, especially for industrial-scale applications where temporary or long-term usage is required.

Innovation Solution

A modular airborne dust collector with a detachable, exchangeable bin system using standardized dumpsters or dump trucks, incorporating tubular filters and a pulse-jet assembly for efficient dust collection and filter cleaning, allowing for easy transportation and servicing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If fixed dust collection equipment is permanently installed, then dust collection effectiveness is improved, but transportability and servicing difficulty worsen

Engineering Contradiction:

Improvedust collection effectivenessVSAvoidtransportability and servicing

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The dust collection system is divided into separate modular components: a reusable collector unit and a disposable collected-dust bin. This segmentation allows the collector to remain fixed for effective dust collection while the bin can be easily removed and replaced for servicing, resolving the contradiction between collection effectiveness and ease of maintenance.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The collected-dust bin is extracted as a separate removable component from the fixed collector system. This extraction enables the bin to be independently handled, transported, and replaced without disturbing the fixed collector infrastructure, thus maintaining dust collection effectiveness while improving transportability and servicing ease.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If standard dust collection bags are used, then dust collection is achieved, but handling and decanting difficulties increase due to spillage risks and special handling requirements

Engineering Contradiction:

Improvedust collection capabilityVSAvoiddust handling and decanting

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system employs disposable collected-dust bins that are sealed and can be easily removed and replaced. These bins eliminate the need for complex handling and decanting operations associated with traditional dust collection bags, as the entire bin can be safely transported and disposed of as a unit, reducing spillage risks and special handling requirements.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Volume of moving object

If vehicle-mounted airborne dust collectors are used for building remediation, then large air volume cleaning capacity is achieved, but cost and accessibility worsen

Engineering Contradiction:

Improveair volume cleaning capacityVSAvoidcost and on-site servicing

Core Design Contradiction:

Volume of moving objectVSEase of operation

Solution Approach 1:

The system separates the large-capacity fixed collector from the collected-dust storage function by using a removable bin. This allows the collector to maintain large air volume cleaning capacity while the bin can be easily accessed, removed, and replaced on-site, reducing servicing costs and improving accessibility without requiring expensive vehicle-mounted equipment.

Inventive Principle:

AI summary

A modular portable dusty air cleaner comprises a removable bin, a dirty gas distributor, an aperture plate, a plurality of tubular filters, a roof, a clean-gas chamber, a dust collection chamber, and a pulse-jet assembly. The dirty gas distributor is positioned to distribute dirty gas into the dust collection chamber from a periphery of the plurality of filters. The aperture plate forms at least a partial ceiling for the bin. The plurality of tubular filters hangs into the bin from the apertures of the plate, one filter per aperture. The roof is positioned above the aperture plate. The clean-gas chamber is defined between the plate and the roof. The pulse jet assembly is positioned at least partly in the clean-gas chamber. The pulse jet assembly includes a plurality of nozzles for pulsing jets of gas down the plurality of filters, one nozzle per filter to dislodge accumulated dust into the bottom of the dust collection chamber.
