Rotating Water Mist Blower for Large Area Dust Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dust suppression systems are limited in their ability to cover large areas effectively, vary mist output and throw distance, and automatically adjust mist angles, making them inefficient for large-scale demolition operations and varying site conditions.
Innovation Solution
A dust suppression apparatus featuring a turntable-mounted water mist blower with a rotating and tilting air conduit, powered by a diesel engine, equipped with a belt drive and constant velocity joint, and an electronic control panel for automated operation, allowing 360-degree horizontal rotation and vertical tilting, along with a booster pump for increased water pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If traditional misting dust suppressors are used, then they can provide dust suppression coverage, but they are limited in the area of coverage and cannot effectively cover very large areas or serve large volumes presented in demolition operations
Solution Approach 1:
The patent implements a turntable mechanism that enables the air conduit to rotate horizontally 360 degrees and tilt vertically, transforming the static misting system into a dynamic one. This allows the system to cover much larger areas by redirecting mist to different locations as demolition operations proceed, resolving the contradiction between coverage area and mist output volume.
Solution Approach 2:
The patent adds rotational and tilting dimensions to the misting system through the turntable and articulated mounting. This transforms a single-direction mist stream into a multi-directional coverage system, effectively increasing the covered area without requiring proportionally larger mist output volume.
2Adaptability or versatility
If fixed-angle mist output is used, then the system structure is simpler, but it cannot automatically direct and redirect misted fluids toward different areas or through different volumes at a given job site
Solution Approach 1:
The turntable and articulated air conduit mounting transform the fixed-angle system into a dynamic, adjustable system. The mechanism allows automatic reciprocating sweep angles and manual positioning to direct mist toward different areas, providing adaptability while maintaining a mechanically simple implementation.
Solution Approach 2:
The turntable-mounted air conduit system serves multiple functions: it can rotate horizontally to cover different azimuths, tilt vertically to adjust elevation angles, and be positioned at various locations. This multi-functional capability allows a single device to adapt to varying site conditions and demolition scenarios.
3Extent of automation
If manual operation of mist angle adjustment is used, then the control system is simpler, but it requires constant labor to vary the aim of the mist output
Solution Approach 1:
The turntable mechanism is designed to enable automatic reciprocating sweep angles without requiring constant manual intervention. The system can autonomously vary the mist output angle through the rotational mechanism, reducing operational labor while maintaining ease of use through simple control interfaces.
4Adaptability or versatility
If fixed mist output volume is used, then the system is easier to control, but it cannot provide versatile dust suppression by varying mist droplet size and density for different applications
Solution Approach 1:
The patent employs multiple nozzles with different spray patterns and droplet sizes that can be selectively activated. By changing which nozzles are engaged and at what pressures, the system can vary mist output volume, droplet size, and density to match different demolition scenarios and wind conditions, achieving adaptability without excessive complexity.

Function Achieved in This Case
The apparatus can efficiently cover up to 20,000 square feet with a modest water volume, providing versatile dust suppression by varying mist output and angle, reducing labor and operational risks due to its diesel-powered and self-sufficient design.
