Problem

Current dust removal systems in the metal processing industry face issues with high viscosity and agglomeration of dust, leading to blockages and corrosion, resulting in short device life and reduced efficiency.

Innovation Solution

A two-stage atomization system with coordinating atomizing balls and umbrella-shaped atomizers, along with a regulating mechanism to adjust clearances and flare angles, ensures effective atomization and contact between water and dust, addressing blockages and corrosion while improving the atomizing effect.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If bag-type dust removal device is used, then dust gas can be filtered, but high viscosity dust with agglomeration tendency blocks micro-holes causing short working life

Engineering Contradiction:
Improvedust removal effectivenessVSAvoidworking life
Core Design Contradiction:
ReliabilityVSDuration of action of moving object

Solution Approach 1:

The patent uses water spray system to create water mist that captures dust particles in the gas stream. Water is introduced through nozzles and atomized to form fine droplets that collide with and capture dust particles, then the water-dust mixture is removed. This hydraulic approach replaces the bag filtration method that clogs with high-viscosity dust.

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Reliability

If fan-leaf-type dust removal device is used, then water mist can be formed to remove dust, but corrosive dust adheres to and corrodes the fan body reducing atomization effect

Engineering Contradiction:
Improvedust removal effectivenessVSAvoidcorrosion and adhesion to fan body
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the atomization function from the rotating fan body and transfers it to a stationary nozzle system. The fan body is completely removed, and water atomization is achieved through high-velocity spray nozzles that generate fine water mist without any rotating components that could be corroded or accumulate dust.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The mechanical rotating fan system is replaced with a stationary pneumatic-hydraulic spray system. Instead of using mechanical rotation to atomize water, the patent uses high-velocity gas flow through nozzles to atomize water, eliminating the mechanical components susceptible to corrosion and dust accumulation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If dense-spout-type dust removal device is used, then water mist can be generated to capture dust, but burrs accumulate on spout surfaces blocking them and reducing working life

Engineering Contradiction:
Improvedust removal effectivenessVSAvoidworking life
Core Design Contradiction:
ReliabilityVSDuration of action of moving object

Solution Approach 1:

The patent removes the dense spout structure entirely and replaces it with a nozzle system that introduces water directly into the high-velocity gas stream. The atomization occurs in the free stream rather than through confined spout openings, eliminating the surfaces where burrs could accumulate and block flow.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent transitions from a confined spout-based atomization approach to a free-stream injection approach. Water is injected into the three-dimensional gas flow field where atomization occurs through turbulent mixing and shear forces, rather than being constrained to two-dimensional spout openings that are prone to blockage.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Reliability

If conventional dust removal equipment is used, then dust can be removed, but frequent clearing of burrs increases labor intensity and reduces efficiency

Engineering Contradiction:
Improvedust removal effectivenessVSAvoidlabor intensity for maintenance
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent designs a system where water is continuously introduced and flows through the atomization zone, naturally carrying away dust particles and preventing accumulation on surfaces. The flowing water serves both the atomization function and the self-cleaning function, eliminating the need for manual clearing operations.

Inventive Principle:
Principle #25Self-service

AI summary

This invention relates to a dust removal system for dust gas which comprises at least an atomizer. The atomizer comprises an atomizing chamber and an atomizing mechanism; the atomizing chamber includes an inlet for the dust gas and an outlet for the gas after mixture; the atomizing mechanism comprises a water chamber, the first atomizing ball, the second atomizing ball, an umbrella-shaped atomizer, and a regulating mechanism; the water chamber includes the first and second water inlet and the first and second water outlet; the regulating mechanism adjusts the fit clearance between the first atomizing ball and the first water outlet, the fit clearance between the second atomizing ball and the second water outlet, and the flare angle of the umbrella surface of the umbrella-shaped atomizer. The preferred advantageous effect is: the two-stage atomization - coordinating the atomizing balls and the water outlets, and using an umbrella-shaped atomizer - guarantees the atomizing effect. When there are burrs accumulating in the water outlets, regulate the fit clearances between the atomizing balls and the water outlets to remove completely the influence of the blockage on the atomizing effect. And when there are burrs corroding the water outlets, regulate the fit clearances between the atomizing balls and the water outlets to remove completely the influence of the corrosion on the atomizing effect.
