Ozone Concentrator with Recycled Vacuum Discharge

Solution Overview

Problem

Conventional ozone concentration methods result in unnecessary ozone discharge due to vacuum discharging and incur energy losses from temperature differences between adsorption/desorption columns.

Innovation Solution

An ozone concentrator design featuring multiple adsorption/desorption columns cooled with a certain-temperature refrigerant, a vacuum pump for concentrating ozone by discharging mainly oxygen, and valves for air pressure operations, where the discharge line from one column is connected to another to recycle ozone, eliminating temperature differences and enhancing energy efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If vacuum discharging is performed to obtain concentrated ozone, then ozone concentration is improved, but ozone is discharged uselessly and energy is wasted

Engineering Contradiction:
Core Design Contradiction:
Manufacturing precisionVSLoss of substance

Solution Approach 1:

The invention recovers ozone that would otherwise be discharged uselessly during vacuum discharging. The discharge line of the vacuum pump is connected to the inlet of the adsorption/desorption column, allowing the discharged gas containing ozone to be reintroduced into the system for further concentration and utilization, thereby preventing ozone waste while maintaining high concentration output

Inventive Principle:
Principle #34Discarding and recovering

2Manufacturing precision

If cooling step is provided after stabilizing and boosting step and desorption step, then ozone concentration is improved, but time loss occurs and temperature difference increases energy loss

Engineering Contradiction:
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The invention eliminates the separate cooling step by maintaining continuous operation of the adsorption/desorption columns. The refrigerant cooling system operates continuously rather than intermittently, and the columns are kept in a constant cooled state throughout the process, eliminating time loss while maintaining temperature uniformity and reducing energy waste from temperature differences

Inventive Principle:
Principle #20Continuity of useful action

3Manufacturing precision

If cooling step is provided after stabilizing and boosting step and desorption step, then ozone concentration is improved, but temperature difference occurs at upper and lower positions increasing energy loss

Engineering Contradiction:
Core Design Contradiction:
Manufacturing precisionVSLoss of energy

Solution Approach 1:

The refrigerant cooling system operates continuously throughout the adsorption and desorption processes, maintaining a constant cooled state in the adsorption/desorption columns. This continuous cooling prevents temperature differences between upper and lower positions, eliminating the energy loss associated with thermal gradients while ensuring consistent ozone concentration

Inventive Principle:
Principle #20Continuity of useful action
