Flexible Hose Explosive Cleaning for Incinerators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning methods for incineration systems, such as boiler cleaning, are inefficient and hazardous due to the use of explosives, requiring system shutdown, posing health risks, and incurring high costs, while existing gas mixture explosion methods have limited reach and handling difficulties.
Innovation Solution
A flexible transport hose system for delivering an explosive mixture to hard-to-reach areas within incineration systems, allowing for remote operation and increased accessibility without the need for explosives, using a gas-impermeable hose with a cooling channel and multiple layers for enhanced safety and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional cleaning methods (boiler knocking, steam jet cleaning, water jet blowers) are used, then cleaning can be performed on shut-down plants, but the cleaning process requires system shutdown for days or weeks, causing significant loss of production or revenue
Solution Approach 1:
The patent replaces conventional mechanical cleaning systems (boiler knocking, steam jet cleaning, water jet blowers) with an explosion-based cleaning system that uses explosive mixtures contained in flexible hoses. The explosive mixture is delivered to the cleaning point and detonated to remove deposits, achieving cleaning in hours rather than days or weeks of system shutdown
Solution Approach 2:
The invention extracts the explosive mixture from rigid containers and delivers it through flexible transport hoses to the cleaning point inside the system. This allows the explosive cleaning agent to be delivered precisely where needed without requiring complete system shutdown or complex scaffolding setups
2Strength
If explosives are used for cleaning, then cleaning power is sufficient to remove hard deposits, but high security measures are required during storage and handling, and special permits are needed
Solution Approach 1:
The explosive cleaning system is segmented into separate components: the explosive mixture is contained within flexible transport hoses that can be delivered to the cleaning point, while the ignition system remains outside the system being cleaned. This segmentation reduces security risks by eliminating the need for large-scale explosive storage and handling within the cleaning area
Solution Approach 2:
The flexible transport hose acts as an intermediary that delivers the explosive mixture from the supply location to the cleaning point inside the system. This intermediary allows the explosive agent to reach difficult-to-access areas without requiring personnel to manually handle explosives within the system, reducing security and safety risks
3Strength
If a rigid cleaning lance is used to deliver explosive mixture, then structural strength is sufficient, but the operating radius is limited and hard-to-reach areas cannot be accessed
Solution Approach 1:
The patent replaces rigid cleaning lances with flexible transport hoses that can dynamically adapt to the geometry of the system being cleaned. The flexible hose can be maneuvered into hard-to-reach areas, coils within itself to navigate tight spaces, and extends the operating radius significantly compared to rigid lance structures
Solution Approach 2:
The invention uses flexible transport hoses as thin-walled containers to deliver the explosive mixture. These flexible hoses can bend, coil, and extend to reach areas that rigid structures cannot access, while still maintaining the integrity of the explosive mixture during transport and delivery
4Strength
If the transport line is rigid, then structural integrity is maintained, but the system cannot reach into the interior of containers or adapt to complex geometries
Solution Approach 1:
The transport line is designed as a flexible hose that can dynamically change its configuration during delivery. The hose can be extended, retracted, coiled, and maneuvered to adapt to the interior geometry of containers and complex system layouts while maintaining structural integrity under pressure
Solution Approach 2:
The transport line uses a flexible hose with sufficient wall strength to contain and transport the explosive mixture under pressure. The flexible shell structure allows the hose to bend and conform to complex geometries while maintaining the integrity required to deliver the explosive agent to the cleaning point
