Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the purifying solution is sprayed in one direction from a plurality of nozzles provided in a nozzle assembly, then the device structure is simple, but the purifying solution is not uniformly distributed over a wide area, resulting in reduced contact ratio with contaminated gas

Engineering Contradiction:

Improvenozzle assembly structureVSAvoidcontact ratio between purifying solution and contaminated gas

Core Design Contradiction:

Device complexityVSQuantity of substance

Solution Approach 1:

The nozzle coupling part is designed to rotate around the support axis, transforming the static spray system into a dynamic one. This rotation enables the spray nozzles to cover a wider area and distribute the purifying solution more uniformly across the contaminated gas flow, increasing the contact ratio without significantly complicating the overall device structure

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The spray nozzles are arranged in a radial direction around the support axis, adding a rotational dimension to the spray pattern. This radial arrangement in multiple dimensions allows the purifying solution to be distributed over a broader area, improving coverage and contact ratio compared to linear one-directional spraying

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Productivity

If a conventional wet scrubber device is used to reduce harmful substances in exhaust gas, then the device can treat dirt, odor and harmful gas, but the removal efficiency is low and harmful substances are not completely removed

Engineering Contradiction:

Improvepurification efficiencyVSAvoidharmful substance content in exhaust gas

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The rotating nozzle coupling part creates a dynamic spray system that continuously moves the purifying solution across different areas of the contaminated gas flow. This dynamic action increases the contact time and contact area between the purifying solution and harmful substances, thereby improving removal efficiency and reducing harmful substance content more effectively than static spray systems

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The spray nozzles are positioned to spray the purifying solution before the contaminated gas exits the housing, creating a liquid membrane or droplets in advance. This preliminary action ensures that harmful substances are neutralized during the gas flow path, improving overall purification efficiency and ensuring complete removal of harmful substances

Inventive Principle:

AI summary

In a nozzle block, a fluid is uniformly sprayed over an entire housing inside through a spray nozzle with the rotation of a nozzle coupling part, thereby increasing a contact ratio of the fluid with contaminated gas and dramatically improving the purification efficiency. Additionally, a fluid for cleaning contaminated gas is allowed to flow opposite to a flow of contaminated gas, so that the contaminated gas and the fluid cancel out, and the contact ratio increases.
