Air treatment apparatus and systems comprised thereof
View Patent ↗This disclosure describes embodiments of an air treatment apparatus that stimulates formation of large moisture droplets from small moisture droplets found in air flowing in power generating systems to a turbo-machine. In one example, the embodiments generate a field that promotes contact between the smaller moisture droplets. This contact can increase the size of moisture droplets to facilitate condensation of moisture out of the air.
1. A system, comprising:
an inlet section for directing ambient air, the inlet section comprising a filter assembly and an air treatment apparatus upstream of the filter assembly, the air treatment apparatus generating an electromagnetic field having a frequency in the electromagnetic spectrum to irradiate air flowing in the inlet section; and
a weather hood disposed upstream of the filter assembly, wherein the electromagnetic field irradiates air in the weather hood.
2. The system of claim 1 , wherein the weather hood forms a plurality of airstreams.
3. The system of claim 1 , wherein the weather hood comprises a channel forming a first airstream and a second airstream, and wherein the air treatment apparatus irradiates at least one of the first airstream and the second airstream.
4. The system of claim 1 , further comprising a guide vane upstream of the filter assembly, wherein the air treatment apparatus comprises an emitter disposed on the guide vane, and wherein the emitter generates the electromagnetic field.
5. The system of claim 1 , wherein the electromagnetic field comprises infrared radiation.
6. The system of claim 1 , wherein the electromagnetic field comprises a plurality of individual electromagnetic fields.
7. The system of claim 1 , further comprising a sensor and a control device coupled with the sensor and with the air treatment apparatus, wherein the control device generates instructions to change a parameter of the electromagnetic field in response to the sensor.
8. The system of claim 7 , wherein the sensor monitors the relative humidity of air in the inlet section.
9. The system of claim 7 , wherein the sensor monitors the relative humidity of air that exits the inlet section.
10. A system, comprising:
a filter assembly;
an emitter disposed upstream of the filter assembly, the emitter generating infrared radiation that irradiates air flowing to the filter assembly; and
a weather hood coupled to an upstream side of the filter assembly.
11. The system of claim 10 , wherein the emitter is positioned inside of the weather hood.
12. The system of claim 10 , further comprising a condensing surface proximate the emitter, wherein the condensing surface receives moisture droplets from the air.
13. The system of claim 10 , further comprising a sensor and a control device coupled with the sensor and with the emitter, wherein the control device generates instructions to change a parameter of the electromagnetic field in response to the sensor.
14. A system, comprising:
a weather hood having an inlet and an outlet; and
an air treatment apparatus disposed in the weather hood, the air treatment apparatus generating an electromagnetic field having a frequency in the electromagnetic spectrum to irradiate air flowing in the weather hood.
15. The system of claim 14 , wherein the weather hood separates the air into a first airstream and a second airstream.
16. The system of claim 15 , wherein the electromagnetic field comprises a first electromagnetic field for the first airstream and a second electromagnetic field for the second airstream.
17. The system of claim 14 , further comprising a condensing surface disposed in the weather hood.
18. The system of claim 17 , wherein the condensing surface is part of a guide vane that extends from the inlet to the outlet, and wherein the air treatment apparatus resides between the inlet and the outlet.
