Movable Intake Gas Purifier with Neutralizing Pellet Beds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional apparatuses for purifying and neutralizing toxic gases are large-scale, fixed outdoor equipment designed for combustion and dry etching processes, lacking a compact, movable, and stand-type solution suitable for indoor use in research laboratories, chemical factories, and hospitals, which fail to effectively address the need for high-efficiency, low-noise, and independent toxic gas purification and neutralization.
Innovation Solution
A compact, movable or stand-type apparatus with a main body containing a pre-filter, HEPA or ULPA filter, neutralizing pellet beds composed of adsorbents and metal oxides, and a blower, equipped with a flexible intake and silent driving mechanism, allowing 360-degree rotation and adjustable positioning for effective indoor toxic gas purification and neutralization without requiring additional connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional large-scale fixed apparatuses are used for toxic gas purification, then purification effectiveness is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent divides the toxic gas purification system into separate functional modules: a movable intake unit that can be positioned independently, and a stationary purification unit containing the filter and neutralizing pellet bed. This segmentation allows the intake to be moved closer to toxic gas sources while keeping the complex purification components in a fixed location, reducing overall device complexity while maintaining purification effectiveness.
Solution Approach 2:
The patent introduces spatial flexibility by allowing the intake unit to move in three-dimensional space around the purification unit. The intake can be positioned at various distances and angles, enabling the system to handle toxic gases from different locations without requiring a large-scale fixed apparatus configuration.
2Reliability
If conventional fixed outdoor equipment is used, then toxic gas treatment capability is improved, but adaptability to indoor environments and mobility are reduced
Solution Approach 1:
The patent makes the intake unit movable and rotatable, allowing it to dynamically adjust its position and orientation to face toxic gas sources from different directions. This dynamic capability enables the system to adapt to various indoor environments and specific gas emission points, unlike fixed outdoor equipment.
Solution Approach 2:
The patent designs the intake unit as a universal component that can be positioned and oriented in multiple configurations to handle toxic gases from various sources within indoor environments. The combination of movable intake and stationary purification unit creates a versatile system applicable to different indoor settings.
3Ease of operation
If household air purifiers are used, then mobility and indoor usability are improved, but toxic gas purification capability is insufficient
Solution Approach 1:
The patent merges the mobility feature of household air purifiers with the advanced toxic gas purification technology of industrial systems. The movable intake unit provides ease of positioning, while the integrated HEPA/ULPA filter and neutralizing pellet bed ensure effective toxic gas purification, combining benefits from both application domains.
Solution Approach 2:
The patent uses a composite filtration system combining HEPA or ULPA filters with neutralizing pellet beds containing specific metal oxides and adsorbents. This composite approach ensures both mobility and high-level toxic gas purification capability by integrating multiple purification mechanisms in a compact, movable configuration.
4Reliability
If additional facilities or pipes are connected, then purification system completeness is improved, but ease of operation and deployment are reduced
Solution Approach 1:
The patent combines the purification filter and neutralizing pellet bed into a single integrated stationary unit, eliminating the need for separate facilities or pipe connections. The movable intake unit connects directly to this integrated unit, simplifying deployment while maintaining complete purification functionality.
