SUSTAINED SUPER-SATURATIONS FOR CONDENSATIONAL GROWTH OF PARTICLES

摘要

An apparatus and method for creating enlarged particles in a flow. The apparatus includes a coiled tube having a tube diameter and a coil diameter, the tube having an input receiving the flow and an output, the tube having a length between the input and the output. A heater heats a first portion of the tube along a first, longitudinal portion of the tube, and a cooler cools a second, longitudinal portion of the tube along at least a second portion of the tube. The method includes heating a first portion of the tube along a first longitudinal portion of the tube, and simultaneously cooling a second portion of the tube along at least a second longitudinal portion of the tube. While heating and cooling, the method includes introducing a flow into an interior of the tube at an input, the flow moving the output.

主权项

1. An apparatus adapted to create enlarged particles in a flow, comprising:
a coiled tube having an inner surface defining a tube cross-section, the coiled tube having a coil diameter, the tube having an input receiving the flow and an output, the tube having a length between the input and the output; a heater configured to heat the tube along a first longitudinal portion of the tube cross-section, the first longitudinal portion of the tube cross-section having a first arcuate position relative to a cross-section of the tube along the length of the tube; and a cooler configured to cool the tube along at least a second longitudinal portion of the tube cross-setion, the second longitudinal portion of the tube cross-section having a second arcuate position relative to a cross-section of the tube along the length of the tube.
