Problem

The manual processing of ash in pyrolysis gasifiers is cumbersome, time-consuming, and poses risks to operators due to high temperatures and potential fires, hindering continuous operation and efficiency.

Innovation Solution

A pyrolysis gasifier equipped with an automatic ash processor that includes a tubular body, a bottom door, a main frame, a base frame, and an automatic ash processing module, which travels along a guide frame to push and remove ash without manual intervention, allowing continuous operation and reducing the risk of operator burns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual ash processing is performed by operators, then the ash can be removed from the bottom door, but the processing time is prolonged and operator safety is compromised due to high temperatures and fire risks

Engineering Contradiction:

Improveoperator safetyVSAvoidash processing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system enables self-service ash removal through the automatic ash processor that autonomously travels along the bottom door, detects ash accumulation, and removes ash without requiring operator intervention. The processor independently performs navigation, ash detection, and removal functions, making the system self-sufficient in ash management tasks.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical ash removal operations with an automated mechanical system. The automatic ash processor uses motorized wheels, automated pushing mechanisms, and sensor-based detection to substitute human operators, eliminating exposure to thermal hazards while maintaining ash removal functionality.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If operators manually scrape ash from the bottom door, then ash removal is achieved, but the process must be interrupted and repeated multiple times, reducing continuous operation efficiency

Engineering Contradiction:

Improvecontinuous operation efficiencyVSAvoidash processing operation

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The automatic ash processor enables continuous ash removal operations by autonomously traveling along the bottom door and removing ash as it accumulates. The system maintains continuous monitoring and removal capabilities without requiring operational interruptions, thereby sustaining pyrolysis gasifier continuous operation and eliminating repeated manual intervention cycles.

Inventive Principle:

Principle #20Continuity of useful action

3Ease of operation

If the bottom door is lowered using hydraulic cylinders and moved laterally using a bogie, then ash access is improved, but additional equipment complexity and potential fire contamination of surroundings are introduced

Engineering Contradiction:

Improveash accessVSAvoiddoor movement mechanism

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The automatic ash processor acts as an intermediary device between the ash accumulation problem and the bottom door structure. Rather than moving the entire bottom door assembly using complex hydraulic and bogie systems, the processor travels along the stationary or slightly movable bottom door, providing ash removal functionality while simplifying the overall mechanical system and eliminating fire contamination risks associated with large-scale door movements.

Inventive Principle:

Principle #24Intermediary (Mediator)
