Iodine Mist Odor Abatement in Waste Transfer Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Waste transfer stations face significant odor issues due to organic materials, with existing solutions like fragrances and odor masking methods being inadequate, and incineration creating additional pollutant and odor problems, leading to community dissatisfaction and regulatory challenges.
Innovation Solution
A system utilizing a misting solution with at least 0.0005% iodine concentration, primarily composed of water or water and alcohol, is applied to create an aerial environment where iodine reacts with odor molecules, effectively reducing odorous gases without leaving residual iodine on waste surfaces, using a misting system that suspends droplets over odor-emitting surfaces for extended periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If incineration is used to eliminate organic materials and odors, then odor abatement is improved, but additional pollutant and odor problems are created
Solution Approach 1:
The patent converts the harmful odor molecules into beneficial iodine-odor compounds through chemical reaction. Iodine reacts with odorous gases to form non-odorous iodine-odor compounds, transforming the harmful odor problem into a beneficial odor elimination process without generating additional pollutants
Solution Approach 2:
The patent changes the chemical state of odor molecules through iodine reaction. By introducing iodine at controlled concentrations (0.0005% or more by weight), the odor molecules undergo chemical transformation into non-odorous compounds, effectively changing the chemical parameters of the waste environment to eliminate odors
2Object-affected harmful factors
If iodine solution is applied directly to waste surfaces, then odor molecules are reacted, but residual iodine remains on waste surfaces
Solution Approach 1:
The patent transitions from surface-level application to aerial environment treatment. Instead of applying iodine solution directly to waste surfaces (2D contact), the system mists iodine into the aerial environment above waste (3D space), allowing odor reactions to occur in the air phase without iodine residue on waste surfaces
Solution Approach 2:
The patent uses mist droplets as an intermediary carrier. Iodine is delivered through water-based mist droplets that evaporate in the aerial environment, leaving iodine vapor to react with odor molecules in the air without requiring direct contact between iodine solution and waste surfaces
3Object-affected harmful factors
If misting system suspends droplets for extended periods, then iodine reacts with odor molecules, but droplet deposition time increases
Solution Approach 1:
The patent utilizes phase transition from liquid mist droplets to vapor. The misted iodine solution evaporates in the aerial environment, transitioning from liquid phase to vapor phase, which allows extended suspension time for odor reactions while the evaporated iodine vapor continues to react with odor molecules without the constraint of droplet gravity and deposition

AI summary
A system for applying a novel odor abating solution to an odor-emitting surface includes a storage compartment comprising a solution of iodine having a concentration of at least 0.0005% by total weight of the solution of I2; a misting system having mist nozzles that are supported over the odor-emitting surface, creating an aerial environment between the odor-emitting surface and the mist nozzles; misting nozzles configured to spray droplets of the solution into the aerial environment over the odor-emitting surface so that, in absence of any air movement exceeding 1 kilometer/hour, at least 75% of the droplets are suspended in the aerial environment over the odor-emitting surface for at least 10 seconds, allowing at least 1% by weight of the I2 in the solution to react with emitted odor before the 75% of the droplets are deposited on the odor-emitting surface. The odor-emitting surface may be within a waste transfer station.
