Solution Overview

Problem

Existing filter devices for separating solids from gases face challenges in modular extension and require complex line connections, limiting their scalability and efficiency.

Innovation Solution

The device features a raw gas chamber with a slide-in part that engages a guide for easy insertion and sealing of filter cartridges, allowing for modular design and expansion without additional costly connections, with a clean gas line that facilitates efficient raw gas flow and pressure distribution, enabling the use of multiple raw gas chambers stacked or side by side for increased filter performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate pressure lines are required for blowing off the lamellar filters, then the filter system can be cleaned effectively, but the device complexity increases and scalability is limited

Engineering Contradiction:
Improvefilter cleaning effectivenessVSAvoidpressure line complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The clean gas line is designed to serve dual functions: transporting clean gas and providing compressed air for filter cleaning. The line includes cleaning openings that allow compressed air to be directed onto the filters from the clean gas side, eliminating the need for separate pressure lines while maintaining effective filter cleaning capability

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention merges the clean gas transport function and the filter cleaning function into a single line system. The clean gas line incorporates cleaning openings that enable compressed air delivery, combining what were previously separate systems into one integrated structure, thereby reducing overall device complexity

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If the filter arrangement is designed for fixed installation, then the sealing and structural integrity are maintained, but the modular expansion capability is reduced

Engineering Contradiction:
Improvesealing integrityVSAvoidmodular expansion capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The filter system is divided into modular filter modules that can be independently installed, removed, and replaced. Each module contains filters mounted on a support structure with integrated sealing elements, allowing the system to be expanded by adding or removing modules without compromising the sealing integrity of the overall system

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system incorporates removable filter modules with sealing elements that can be easily installed and removed. The sealing design maintains integrity during operation while allowing for dynamic reconfiguration and expansion of the filter system by adding or removing modules as needed

Inventive Principle:
Principle #15Dynamics

3Productivity

If multiple raw gas chambers are stacked for increased capacity, then the filter performance is enhanced, but the number of additional line connections required increases complexity

Engineering Contradiction:
Improvefilter performanceVSAvoidline connections
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The clean gas line serves multiple functions across multiple chambers: it transports clean gas from all chambers and provides compressed air for cleaning filters in all chambers. This multi-functional design allows multiple chambers to be connected without requiring separate pressure lines for each chamber, thereby enhancing filter performance while minimizing the increase in line connection complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A device for separating solids from gases is described, comprising a raw gas chamber (1) connectable at the top to a raw gas channel (17) and at the bottom to a discharge hopper (18), and at least one filter (4) arranged in the raw gas chamber (1), the flow channel of which is enclosed by a filter jacket and allows flow from bottom to top to a clean gas chamber (3). To enable an advantageous modular design, it is proposed that the filter (4) be connected to a clean gas line (6) running through the raw gas chamber (1), which is open at the top and bottom, and which opens into the clean gas chamber (3), which is laterally adjacent to the raw gas chamber (1).
