Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The pressurization type gasification furnace requires complex structures with piping, pressure gauges, and valves, and applying a pressure equalizer from a related apparatus is not feasible due to length constraints.
Innovation Solution
A gasification apparatus with a pressure vessel, a gasification furnace inside, a heat exchanger, a char-receiving section above the heat exchanger, and pressure equalizers that communicate with the furnace and open into the char-receiving section, along with a gas flow channel through the char-receiving section, to control differential pressure and catch char effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If piping, pressure gauges, pressurizing and purifying gas supply piping, opening and closing valves are used to equalize pressure between space section and furnace body, then pressure control is achieved, but device complexity increases
Solution Approach 1:
The patent extracts the pressure equalization function from the complex piping system with valves and pressure gauges, implementing it through a simple pressure equalizer tube that passively balances pressure between the space section and furnace body without requiring active control components
Solution Approach 2:
The pressure equalizer tube operates automatically based on pressure differential, allowing the system to self-regulate pressure balance between space section and furnace body without external control mechanisms or complex piping arrangements
2Reliability
If pressure equalizer is extended to lower side to control differential pressure, then pressure control is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent positions the pressure equalizer tube vertically extending from the space section toward the furnace body, utilizing the vertical dimension to achieve pressure equalization without requiring horizontal extension or complex lateral piping arrangements

AI summary
A gasification apparatus that is capable of appropriately controlling a differential pressure variation between the interior of a pressure vessel and the interior of a gasification furnace, and of simplifying a structure, by providing: a pressure vessel which forms a hollow shape; a gasification furnace which forms a hollow shape, and which is positioned inside the pressure vessel with a space section therebetween; a heat exchanger positioned at the upper section of the gasification furnace; a gas nozzle which supplies seal gas to the lower section of the space section; a char-receiving section provided above the heat exchanger in the space section; a pressure equalizer of which one end communicates with the interior of the gasification furnace, and the other end opens into the char-receiving section; and a gas flow channel which passes vertically through a side section of the char-receiving section.
