Solution Overview

Problem

Existing liquid ring pumps face inefficiencies in heat transfer and condensation of vapors due to high gas velocities and lack of integrated components for managing fluid flow and maintenance access.

Innovation Solution

A liquid ring pump manifold with integrated non-return valves and spray nozzles that split gas flow into multiple branches, allowing for improved heat transfer through increased contact time with operating liquid, and facilitates easy maintenance via a removable cover and access port.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a single large spray nozzle is used in the manifold, then less nozzles are needed, but the nozzle size increases and contact time with gas flow decreases

Engineering Contradiction:
Improvenumber of spray nozzlesVSAvoidcontact time between operating liquid and gas
Core Design Contradiction:
Quantity of substanceVSDuration of action of moving object

Solution Approach 1:

The single large spray nozzle is segmented into multiple smaller spray nozzles distributed throughout the manifold. This segmentation allows the operating liquid to be injected at multiple locations along the gas flow path, increasing the total contact time between the liquid and gas while maintaining a reasonable number of nozzles.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The spray nozzles are distributed in multiple spatial dimensions within the manifold rather than concentrated in one location. This dimensional distribution ensures that gas flow encounters spray zones at different positions and times, effectively increasing contact time without requiring a single large nozzle.

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

2Adaptability or versatility

If multiple separate components are used for fluid management, then functionality is improved, but installation height and material costs increase

Engineering Contradiction:
Improvefluid management functionalityVSAvoidinstallation height
Core Design Contradiction:
Adaptability or versatilityVSLength of stationary object

Solution Approach 1:

Multiple separate components for fluid management (spray nozzles, non-return valves, flow distribution elements) are merged into a single integrated manifold structure. This consolidation maintains all necessary fluid management functionalities while reducing the overall installation height and material requirements by eliminating the need for multiple separate assemblies.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The manifold is designed as a multi-functional component that simultaneously performs fluid distribution, spray injection, and non-return valve functions. This universal design approach allows a single component to replace multiple specialized components, reducing installation height and material costs while maintaining comprehensive fluid management capability.

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

3Adaptability or versatility

If multiple separate components are used for fluid management, then functionality is improved, but connections and leakage risks increase

Engineering Contradiction:
Improvefluid management functionalityVSAvoidleakage risk
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

Multiple fluid management components are merged into a single integrated manifold with internal flow paths and sealed connections. This integration eliminates numerous external connections and joints that would be present if separate components were used, thereby reducing leakage risks while maintaining comprehensive fluid management functionality.

Inventive Principle:
Principle #5Merging (Combining)

4Ease of repair

If internal components are made accessible for maintenance, then ease of maintenance is improved, but device complexity increases

Engineering Contradiction:
Improvemaintenance accessibilityVSAvoidmanifold structure
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The manifold is segmented with removable sections or access ports that allow internal components to be accessed for maintenance. This segmentation strategy provides maintenance accessibility without requiring the entire manifold to be complex or disassembled, balancing ease of repair with structural integrity.

Inventive Principle:
Principle #1Segmentation

Function Achieved in This Case

Enhances condensation of vapors, reduces installation height and material costs, and improves efficiency by reducing connections and leakage risks, while enabling easier maintenance of internal components.

Implementation Method 1

contact time between the sprayed operating liquid and the gas tends to be increased. This tends to provide for improved heat transfer from the gas to the sprayed operating liquid, which in turn tends to cause more condensation of vapour in the gas

Methodology Applied
Scientific EffectHeat transfer: Conduction (thermal)

Implementation Method 2

improved heat transfer from the gas to the sprayed operating liquid, which in turn tends to cause more condensation of vapour in the gas
