Solution Overview

Problem

Pressure-regulating valves (PRVs) in pressurized water lines of existing technologies have a limited life span, resulting in expensive recurring costs and downtime, affecting revenues of the mine or other industries, resulting in recurring expenses and downtime, affecting the PRV's ability to effectively regulate pressure in the water lines, leading to costly maintenance and downtime.

Innovation Solution

An energy-recovery system with an integrated pressure-regulating valve (PRV) that diverts water flow to bypass the turbine during failures, ensuring pressure regulation and energy generation, featuring a spiral water-flow adapter and a PRV connected in parallel with the turbine to handle pressure regulation and energy recovery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a pressure-regulating valve is used to regulate pressure in water lines, then pressure regulation is achieved, but the valve has limited life span requiring periodic servicing and replacement

Engineering Contradiction:
Improvepressure regulation reliabilityVSAvoidPRV life span
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent combines the pressure regulation function with an energy recovery turbine, creating a dual-function device. The turbine serves as both an energy generation device and a pressure-regulating mechanism, eliminating the need for a separate PRV and its associated maintenance requirements.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The energy recovery turbine performs multiple functions: generating electricity from water flow and regulating pressure in the water line. This multi-functionality replaces the single-function PRV, extending system life and reducing maintenance needs.

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

2Reliability

If a pressure-regulating valve is used to regulate pressure, then pressure control is maintained, but expensive recurring maintenance costs and downtime occur

Engineering Contradiction:
Improvepressure control capabilityVSAvoiddowntime for maintenance
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

By merging pressure regulation with energy recovery in a single turbine device, the system eliminates the separate PRV that requires maintenance. The turbine's mechanical nature and continuous operation reduce downtime compared to periodic PRV servicing.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The energy recovery turbine regulates pressure through its own operation of extracting energy from water flow, without requiring external intervention or separate control mechanisms. This self-regulating capability reduces maintenance needs and downtime.

Inventive Principle:
Principle #25Self-service

3Power

If the turbine shuts down or becomes inoperative, then energy generation stops, but pressure regulation must be maintained as a failsafe

Engineering Contradiction:
Improveelectric power generationVSAvoidpressure regulation during failure
Core Design Contradiction:
PowerVSReliability

Solution Approach 1:

The patent incorporates a pressure-regulating valve as a pre-configured backup system that automatically activates when the turbine fails. This preliminary arrangement ensures immediate pressure regulation without delay, maintaining system reliability during turbine shutdown.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The PRV serves as a protective backup mechanism prepared in advance to handle turbine failures. This cushioning approach ensures that pressure regulation continues even when the primary energy-generating component becomes inoperative.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

AI summary

An energy-recovery system has an energy-recovery turbine to receive a flow of water from a water line to which the turbine is connected and to generate electric power from the flow of water while also regulating water pressure in the water line. The system also includes a pressure-regulating valve (PRV) connected in parallel with the turbine to regulate the water pressure in the water line only when the turbine is inoperative. The system includes a spiral water-flow adapter having a water inlet for connecting to an upstream portion of the water line and a water outlet for connecting to a downstream portion of the water line, the spiral water-flow adapter directing the flow of water from the water inlet into the turbine and then to the water outlet.
