Smoke Removal Device Combustion Unit Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional combustion devices generate particulates that pollute the environment and pose health risks when inhaled, and existing solutions like filter elements are costly and impractical for large burners.
Innovation Solution
A smoke removal device with a combustion unit that includes a main body, gas pipeline, and lighter, where the smoke passes through a smoke passage and is burned by a fire generated by the ignition of fuel gas, reducing interference from air flow and enhancing particulate combustion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a filter element or filter net is installed on the smoke discharge route to filter particulates, then the environmental pollution and health risks are reduced, but the cost increases and regular replacement is required
Solution Approach 1:
The patent converts the harmful smoke containing particulates into a beneficial process by directing it through a combustion chamber where it is burned. The smoke that would normally be harmful is instead used as fuel to generate heat, effectively converting the harmful exhaust into a useful energy source while eliminating particulates through combustion.
Solution Approach 2:
The system uses the smoke itself to fuel the combustion process. The smoke containing particulates is directed into the combustion chamber where it ignites and burns, using its own combustible components to generate heat. This self-sustaining process eliminates the need for external fuel supply and continuous filter replacement.
2Object-affected harmful factors
If a filter element or filter net is used to filter particulates, then the smoke quality is improved, but the device complexity and maintenance cost increase
Solution Approach 1:
The patent extracts the filtering function from a separate mechanical filter system and integrates it directly into the combustion process. By removing the particulates through combustion within the smoke passage itself, the need for separate filter elements and complex filtration systems is eliminated, simplifying the overall device structure.
Solution Approach 2:
The patent merges the smoke passage with the combustion chamber, combining the exhaust pathway with the fuel combustion process. The smoke passage serves dual purposes: as the exhaust channel and as the combustion chamber where particulates are burned. This integration eliminates the need for separate filtration components.
3Productivity
If the burner size is increased to handle more smoke, then the smoke removal capacity is improved, but the filter replacement becomes more difficult and costly
Solution Approach 1:
The patent converts the harmful smoke containing particulates into a beneficial process by directing it through a combustion chamber where it is burned. The smoke that would normally be harmful is instead used as fuel to generate heat, effectively converting the harmful exhaust into a useful energy source while eliminating particulates through combustion.
Solution Approach 2:
The system uses the smoke itself to fuel the combustion process. The smoke containing particulates is directed into the combustion chamber where it ignites and burns, using its own combustible components to generate heat. This self-sustaining process eliminates the need for external fuel supply and continuous filter replacement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively burns particulates in the smoke, reducing environmental pollution and health risks, while minimizing the impact of air flow on fuel gas concentration and eliminating the need for frequent filter replacements.
Implementation Method 1
A lighter (24) is provided in the central passage (G) to ignite the fuel gas in the central passage (G) to generate a fire
Implementation Method 2
the fire then burns the particulates in the smoke passing through the smoke passage (C)
Implementation Method 3
the fire then burns the particulates in the smoke passing through the smoke passage

AI summary
A smoke removal device (100, 100A, 100B), which can burn the particulates in the smoke efficiently, includes a tube body (14) and a combustion unit. The combustion unit is provided in the tube body (14) and includes a main body (20), a gas pipeline (22), and a lighter (24). The main body (20) is located at a first end of the tube body (14). A smoke passage (C) is formed between a periphery of the main body (20) and an inner wall of the tube body (14), and the smoke enters the smoke removal device through the smoke passage (C). The main body (20) has a central passage (G) therethrough, where a fuel gas is ignited. The fuel gas is guided to the central passage (G) through the gas pipeline (22) and then ignited by the lighter (24) to burn the smoke particulates passing through the smoke passage (C).
