Abstract: An improvement for a self-balancing shielded bipolar ionizer (U.S. Pat. No. 6,002,573), which uses pressurized air or nitrogen to increase performance, extend the operating distance range, and reduce cleaning frequency. An air assist assembly is inserted into the ion generation cavity, which directs pressurized air or nitrogen past the electrodes. In applications where little natural airflow exists, air assist technology is particularly useful. Ions are blown toward the target. This directs the ions to where they are needed, and delivers ions faster. Useful operating distances are increased. Faster delivery minimizes ion losses due to recombination. Furthermore, pure pressurized air protects the electrodes from impurities in the environmental air. Less chemical growth affects electrode performance. Hence, the ionizer exhibits more stable performance, plus the need for electrode cleaning is minimized.

Abstract: A first stream of pressurized gas is directed at high toward a target area through an ionization chamber. As the high-speed, pressurized gas flows through the ionization chamber, a low-pressure region is used to draw a second stream of gas into the ionization chamber. The second stream of gas is drawn into the ionization chamber from the target area. Re-circulation of gas from the target area supplements the pressurized gas, thereby increasing the efficiency of ionization while reducing the volume of pressurized gas that must be consumed. This helps to prevent recombination while increasing the rate of flow of ionized gas to the target area. A cost-effective, safe, low-level radiation source is used to direct soft X-rays through a filtering window at the gas as it passes through the ionization chamber. Use of the filtering window physically separates the low-level radiation source from the ionization chamber and only allows soft X-rays to pass into the chamber.
