Solution Overview

Problem

Conventional chlorine analyzing apparatuses face challenges in efficiently treating the vapor of acetic acid discharged from the titration cell, often requiring larger devices to achieve effective neutralization, which complicates the apparatus design.

Innovation Solution

The apparatus incorporates a deodorization tube heated by the electric furnace to decompose the vapor of acetic acid, allowing for efficient treatment without increasing the apparatus size by utilizing the existing heat source.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a removing device is used to neutralize acetic acid vapor discharged from the titration cell, then the vapor can be treated, but the device size must be enlarged to achieve complete treatment

Engineering Contradiction:
Improveacetic acid vapor dischargeVSAvoidremoving device size
Core Design Contradiction:
Object-affected harmful factorsVSVolume of stationary object

Solution Approach 1:

The deodorization tube is integrated into the electric furnace structure, merging the vapor treatment function with the existing heating system. The electric furnace's heating zone is extended to include the deodorization tube, allowing acetic acid vapor to be decomposed by the furnace's heat without requiring a separate treatment device.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The electric furnace performs multiple functions: it heats the reaction tube for chlorine compound decomposition and simultaneously heats the deodorization tube for acetic acid vapor treatment. This multi-functionality eliminates the need for dedicated vapor treatment equipment.

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

2Reliability

If the treating performance of the removing device is increased, then acetic acid vapor can be completely treated, but the size of the removing device must be enlarged

Engineering Contradiction:
Improvevapor treatment effectivenessVSAvoidremoving device size
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

The acetic acid vapor is treated using the heat already generated by the electric furnace for its primary heating function. The system uses its own operational heat to decompose the vapor, eliminating the need for additional heating equipment or larger treatment devices.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The acetic acid vapor, which is a harmful byproduct, is converted into a beneficial treatment opportunity by using the electric furnace's heat to decompose it. The vapor passes through the heating zone where it is thermally decomposed into less harmful substances, turning a waste treatment problem into an integrated process feature.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)
