Two-Substance Nozzle for Gas Line Odorization

An evaporative body is introduced as an intermediary component between the odorant injection point and the gas stream. The liquid odorant is applied to the evaporative body surface, where it evaporates before mixing with the gas stream. This mediator ensures complete evaporation and controlled distribution, preventing liquid odorant accumulation in the gas line.

The patent replaces direct mechanical injection of liquid odorant into the gas stream with a thermal evaporation process. Instead of forcing liquid odorant directly into the high-velocity gas flow, the system uses heat transfer from the gas stream to the evaporative body, converting liquid odorant to vapor in a controlled manner before mixing.

The evaporative body is designed with a porous structure that provides a large internal surface area for odorant evaporation within a compact volume. The porous material allows liquid odorant to be distributed throughout its structure, creating numerous evaporation sites without requiring a large external dimension, thus maintaining low device complexity while achieving high evaporation rates.

The evaporative body utilizes three-dimensional porous structure to maximize surface area within a small footprint. By transitioning from a two-dimensional surface to a three-dimensional volumetric structure with internal porosity, the system achieves large evaporation surface area without increasing external dimensions or device complexity.

The evaporative body is designed to be self-regulating, automatically adapting to different gas volume flows without external control. The gas stream itself provides the heat for evaporation and the flow dynamics automatically adjust the evaporation rate to match the gas flow, eliminating the need for pressure-regulated nozzles and enabling operation across a wide range of gas volume flows.

The system allows the evaporation parameters to change dynamically with gas volume flow. As gas flow increases, the heat transfer and mass transfer rates automatically increase, adjusting the evaporation rate to match the higher gas volume. This parametric adaptation enables consistent odorant concentration across varying operating conditions without requiring active control or pressure regulation.
