Patent number: 5199486Abstract: A heat exchange humidifier for generation of steam-to-steam or fluid-to-steam humidity may include at least one steam tube in a heat exchanger array which may be coated with a non-stick surface such as tetrafluoroethylene (TEFLON.RTM.) coating or the like, to prevent the build-up of minerals. The steam tubes in the heat exchanger array are in a substantially layered configuration, each layer being offset and below the preceding upper layer, or in helical configuration. This organization of the tubes in the heat exchanger array maximizes convection currents in a fluid surrounding the steam tubes to minimize dead water films and maximize heat transfer from the steam or fluid inside of the tubes to the surrounding water, resulting in an overall increase in boil-off capacity for adding humidity to the air.Type: GrantFiled: January 27, 1992Date of Patent: April 6, 1993Assignee: Dri-Steem Humidifier CompanyInventors: Rick D.

Patent number: 4822385Abstract: An exhaust hood includes a collection chamber with a converging inlet passageway which directs the rising fume laden air downwardly toward a reverse turning area from which a baffled cleansing chamber extends upwardly. The collection chamber has a large top air capture pocket above the inlet passageway. The cleansing chamber includes alternating baffles on the opposite walls and generally a V-shaped in cross section with a smooth apex. The baffles define a generally serpentine for a mechanical cleansing path. The air cleansing nozzles permit periodic washing of the cleansing chamber surfaces. A common wall between the inlet passageway and cleansing chamber is pivotally mounted for access to the chamber. A water bath may form the bottom wall of the turning area. The stream angularly engages the bath with bath effective agitation, atomization and turbulence for mixing and removal of foreign matter from the air which then turns and moves through the cleansing chamber.Type: GrantFiled: July 14, 1987Date of Patent: April 18, 1989Assignee: Maysteel CorporationInventors: Gary L.
