Solution Overview

Problem

Existing methods for separating solid particles from mist aerosols, particularly those with solution droplets, suffer from impaired separation efficiency.

Innovation Solution

A column collector with a chamber equipped with an inlet at the lower part, an outlet at the upper part, heating elements, movable baffles arranged alternately, and cleaning means, including a suction device with a filter and scraper edges, to force aerosol flow and precipitate solid particles on the baffles for efficient separation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If turbulent flow methods are used to separate solid particles from aerosol, then kinetic energy of particles is converted to thermal energy for separation, but separation efficiency for mist aerosols with solution droplets is impaired

Engineering Contradiction:
Improveseparation efficiencyVSAvoidcomplexity of separation process
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent changes the physical parameter of temperature by introducing heating elements to heat the aerosol flow. This causes solution droplets to evaporate and solid particles to precipitate, fundamentally changing the separation mechanism from kinetic energy conversion to thermal-driven precipitation, thereby improving separation efficiency for mist aerosols

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent divides the separation process into distinct stages using multiple baffles arranged in sequence: first heating and precipitation stage, then separation stage where particles deposit on baffle surfaces. This segmented approach allows each stage to optimize for its specific function, improving overall separation efficiency

Inventive Principle:
Principle #1Segmentation

2Reliability

If solid particles are deposited on fixed baffles for separation, then separation is achieved, but removal and cleaning of deposited particles becomes difficult

Engineering Contradiction:
Improveseparation efficiencyVSAvoidease of particle removal
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The patent makes the baffles movable rather than fixed, allowing them to be repositioned or removed from the chamber. This dynamic design enables easy access to deposited particles for cleaning and maintenance, solving the problem of difficult particle removal while maintaining separation efficiency during operation

Inventive Principle:
Principle #15Dynamics

3Reliability

If heating elements are added to precipitate solid particles from aerosol, then separation efficiency improves, but energy consumption increases

Engineering Contradiction:
Improveseparation efficiencyVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies heating partially - only to the extent necessary to achieve precipitation of solid particles from the aerosol. The heating elements are positioned strategically and controlled to provide just sufficient thermal energy for separation, avoiding excessive energy consumption while maintaining effective separation efficiency

Inventive Principle:
Principle #16Partial or excessive action
