Solution Overview

Problem

Existing filtering systems for removing aerosols and particulates from gas streams face difficulties in maintenance and replacement, particularly when filtering elements are installed far from the top or end of the vessel, requiring personnel to enter the vessel for access.

Innovation Solution

A filtering system with an impermeable extension for the filtering element, allowing for secure installation and easy removal during maintenance or replacement, where the extension is used to insert and secure the filtering element into the vessel, enabling pressurized gas to pass through while allowing for external access and removal without entering the vessel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If filtering elements are installed far from the top or end of the vessel to optimize filtration performance, then filtration efficiency is improved, but maintenance and replacement become difficult requiring personnel to enter the vessel

Engineering Contradiction:

Improvefiltration efficiencyVSAvoidmaintenance accessibility

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The filtering element is divided into two main parts: the filtering portion (with filtering medium) and the extension portion (impermeable extension). This segmentation allows the filtering element to extend beyond the vessel opening, enabling external access for maintenance while maintaining optimal installation depth for filtration efficiency.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The impermeable extension acts as an intermediary component that connects the filtering element to the external environment. It provides a means for personnel to access and manipulate the filtering element from outside the vessel without needing to enter the vessel interior, thus resolving the accessibility issue while maintaining filtration performance.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If filtering elements are installed deep in the vessel to maximize gas contact time, then filtration effectiveness is improved, but removal and replacement require vessel entry increasing safety risks

Engineering Contradiction:

Improvefiltration effectivenessVSAvoidsafety risks

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

By segmenting the filtering element into a filtering portion and an extension portion, the design allows the filtering portion to extend deep into the vessel for effective gas contact while the extension portion remains accessible from outside, eliminating the need for personnel entry and associated safety risks.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The extension portion serves as an intermediary that bridges the gap between the deep-installed filtering element and the external environment. It enables safe removal and replacement operations from outside the vessel while maintaining the deep installation position needed for filtration effectiveness.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If filtering elements are made longer to extend deeper in the vessel, then filtration performance is improved, but handling and installation become more difficult

Engineering Contradiction:

Improvefiltration performanceVSAvoidhandling and installation

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The filtering element is segmented into a filtering portion (for performance) and an extension portion (for handling). This allows the element to achieve the necessary length for deep vessel installation while having a distinct section optimized for external manipulation and installation operations.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different portions of the filtering element have different properties: the filtering portion has permeable medium for filtration performance, while the extension portion has impermeable solid structure for ease of handling and installation. This local differentiation optimizes each section for its specific function.

Inventive Principle:

Principle #3Local quality
