Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smoke and poisonous gas removal apparatuses do not effectively remove smoke and poisonous gases, leading to air pollution and hazards during fires, and they consume separate energy, which is inefficient and contributes to global warming.
Innovation Solution
A sprinkler system integrated with a smoke and poisonous gas removal apparatus that uses a flux unit, nozzle, and frame to create a vacuum state for sucking smoke and gases, utilizing water pressure to mix with hot, light, and high-pressure smoke and gases, without separate energy consumption, and includes features like Jabara-type multi-stage rings, vortex generating units, and filters for efficient removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If smoke ventilation apparatuses are used to emit smoke and poisonous gas into air, then smoke can be dispersed, but air pollution from smoke and poisonous gas becomes inevitable
Solution Approach 1:
The patent converts the harmful smoke and poisonous gases into a beneficial state by using water spray to cool and condense them, transforming the hot, buoyant smoke into cooled droplets that can be effectively collected and removed through the water drainage system, thereby eliminating both inhalation hazards and air pollution
Solution Approach 2:
Water acts as an intermediary substance between the smoke source and the environment. The water spray from sprinklers serves as a medium that absorbs smoke particles and poisonous gases through condensation and dissolution, then transports them via drainage pipes to removal points, preventing direct emission into the atmosphere
2Object-affected harmful factors
If separate smoke removal apparatuses are installed, then smoke can be vented, but excessive energy consumption occurs
Solution Approach 1:
The patent merges the smoke removal function with the existing sprinkler system by integrating smoke suction inlets and water spray nozzles into a unified apparatus. The sprinkler water supply system simultaneously provides both fire suppression water and smoke cooling water, while the drained water serves dual purposes of fire extinguishment and smoke particle removal, eliminating the need for separate powered ventilation equipment
Solution Approach 2:
The system uses its own water spray and drainage infrastructure to perform smoke removal without requiring external energy input. The water sprayed by the sprinklers naturally cools and condenses smoke, and the existing drainage system automatically removes the contaminated water, creating a self-sufficient smoke removal mechanism that leverages the system's inherent resources
3Reliability
If traditional sprinklers are used for fire suppression, then early fire suppression is achieved, but no response to poisonous gas caused by fire is provided
Solution Approach 1:
The patent transforms the single-function fire suppression sprinkler into a multi-functional apparatus that simultaneously performs fire suppression, smoke cooling, and poisonous gas removal. The same water spray mechanism that extinguishes fire also cools and condenses smoke and gases, while the integrated suction system captures and removes these contaminants, providing comprehensive protection against multiple fire-related hazards
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
The system effectively removes smoke and poisonous gases without separate energy consumption, reducing CO2 emissions, is economical, easy to maintain, and can be reused, providing safe air and reducing human risk from smoke inhalation during fires.
Implementation Method 1
When the flux unit, nozzle, and frame spray fluid at a certain pressure and high speed through the nozzle, pressure energy of the fluid is changed to velocity energy
Implementation Method 2
forming a vacuum state in the suction room at a low pressure from the fast speed. The suction part is then positioned to surround the nozzle, and the frame is positioned surrounding the heat sensitive unit, forming the operation of a vacuum ejector for sucking another fluid

AI summary
Provided is an apparatus for removing smoke and poisonous gas. The apparatus includes a body configured to include a flux unit which supplies water and a nozzle which is connected to the flux unit and has a narrower width than the flux unit, a frame configured to surround the body and include a suction part for removing smoke, and a heat sensitive unit fixed to seal the nozzle. When the flux unit, nozzle and frame sprays fluid with a certain pressure at high speed through the nozzle, pressure energy of the fluid is changed to velocity energy, and a vacuum state is formed in a suction room at a low pressure due to a fast speed. In order for an operation to be performed as a vacuum ejector for sucking another fluid, the suction part is positioned surrounding the nozzle, and the frame is provided to surround the heat sensitive unit. A negative pressure explained in Bernoulli's theorem is generated to form a vacuum in the space between the nozzle and the mixing chamber, thus enabling the suction of smoke and poisonous gas. The smoke and poisonous gas are mixed with water in the mixing chamber so as to be trapped in the water or dissolved and dispersed in the water. The suction part is formed in the area which encloses the nozzle such that the suction part can operate together with a vacuum ejector. The frame is arranged so as to enclose the heat sensitive unit.
