20080302241 | Structural Principle of an Exhaust Gas Purification Installation, and Associated Method For Purifying an Exhaust Gas - In an exhaust gas cleaning system, a built-in cleaning section is embodied as an upright U, in which a first leg includes an ionizing zone to ionize particles or aerosols carried in the gas. The gas flows from above into the first leg and downward in a direction of gravity through the ionizing zone. A second leg includes a collector to separate the particles or aerosols from the gas flow, which flows into and through the collector in a direction from below and upward, counter to the direction of gravity. A spraying device is mounted above the collector to rinse the collector. A transition from the first to the second leg includes a connecting zone including a container to collect the particles or aerosols separated of the gas, which container includes a discharge pipe disposed at a lowest point of the container to discharge the liquid enriched with the particles. | 12-11-2008 |

20090114091 | Apparatus For Producing Water And Dehumidifying Air - An apparatus for producing water and dehumidifying air is described. The apparatus causes moisture in an incoming air stream to combine with seed water to remove moisture from the incoming air stream, and may be used to generate water from air, dehumidify air, cool air, and the like. The ability to generate water from air has global importance as the need for clean water increases each year. The apparatus for producing water and dehumidifying air uses high voltage but extremely low current, allowing for both safe and energy efficient operations. The apparatus for producing water and dehumidifying air uses a vessel containing seed water, a bubbler immersed in the seed water, a high voltage source connected to a lower electrode and an upper electrode connected to the negative side of the high voltage source. An airflow path travels through the apparatus and water molecules are extracted from the air as it passes through the apparatus. | 05-07-2009 |
