Condensation Of Gas Or Vapor Patents (Class 34/449)
  • Patent number: 9958205
    Abstract: Exhaust air from a coater drier is sent to a desorption zone of a VOC concentration rotor. Air which comes out of the desorption zone is sent to a heat exchanger and cooled, the cooled air which comes out of the heat exchanger is sent to a cooling coil which carries out VOC concentration recovery. Air which comes out of the cooling coil is sent to an absorption zone of the VOC concentration rotor. Air which comes out of the absorption zone is sent to the heat exchanger and heated. The heated air which comes out of the heat exchanger is sent to a heating coil to be used as supply air for a coater drier. A heat pump can be used for the cooling coil which carries out cooling condensation of the organic solvent and the heating coil which heats purified air as air supply for the coater drier.

  • Patent number: 8850715
    Abstract: What is described is a process and an installation for drying articles, in particular painted vehicle bodies, in which the articles are moved through a drying zone in which they are hardened in an inert-gas atmosphere. Inert gas is taken from the drying zone constantly or intermittently and is first of all conducted along a first face which is at a first temperature at which higher-boiling contaminants condense out. The condensate that forms in the process is discharged. After that, the inert gas which has been pre-cleaned in this way is conducted along at least one second face which is at a lower temperature than the first face. Lower-boiling contaminants are precipitated at this point. These condensates, too, are then discharged. This process and installation work more favorably, energy-wise, and with higher cleaning efficiency than known processes and installations of a similar type.

  • Patent number: 6381872
    Abstract: A mixture of lower alcohols whose mean molecular weight is 46 or less is supplied onto a surface of a semiconductor wafer cleansed with water. With this supply, the amount of alcohols left on the semiconductor wafer which has been dried can be suppressed to 2 ng/cm2 or less, and thus a gate oxide film formed on the semiconductor wafer is prevented from deterioration. As a result, a high yield of semiconductor products can be realized.

  • Patent number: 6289605
    Abstract: The present invention provides a drying method for removing a residual solution from a semiconductor wafer. The semiconductor wafer is placed into a chamber, and then the air pressure of the chamber is lowered from atmospheric pressure to a lower pressure. Next, an inert gas with a predetermined pressure is injected into the chamber to exchange with the dissolved oxygen in the residual solution. The pressure in the chamber is reduced to 0.5˜100 torr so as to lower the boiling point of the solution and to remove the displaced oxygen. Finally, a heating process is performed to completely evaporate the residual solution on the semiconductor wafer.

  • Patent number: 5711086
    Abstract: Apparatus for continuous drying of moist materials in superheated steam comprises a drying enclosure 10, open-ended inlet and outlet ducts 11, 12 communicating with the enclosure, and conveyors 13, 14, 15 for conveying the material to be dried along the inlet duct, through the enclosure and along the outlet duct. Superheated steam is generated in the enclosure from the moisture in the material 19 being dried by circulating the initial gas within the enclosure between a heat source 23 and the material, and/or by the injection into the enclosure of superheated steam from an external source. The inlet duct 11 and outlet duct 12 both extend downwardly from the enclosure 10 and a vent duct 22 from the enclosure has an outlet 26 normally at a level midway along the two ducts. In use, superheated steam tending to pass downwardly along the ducts meets external air tending to pass upwardly along the ducts and forms within each duct a temperature and density differential stratification layer 21.

  • Patent number: 5383289
    Abstract: A drying system for drying textiles. The textile drying system includes an enclosed dryer having heating elements located therein, a feed system for continuously feeding textiles through the dryer, and a dehumidifier for directing conditioned air into the dryer. The textiles are dried in the dryer due to a combination of the heating elements located in the dryer and the conditioned air directed into the dryer by the dehumidifier. The dehumidifier conditions the ambient air to a selected temperature and relative humidity, and directs this air into the dryer. An exhaust port located in the dryer provides an opening for air within the dryer to exit to the atmosphere. The speed at which textiles are advanced through the dryer by the feed system is controlled by a moisture sensor which senses the moisture content of the textile goods exiting the dryer 12 and controls the speed of the feed system accordingly.

  • Patent number: 5373647
    Abstract: A method and a system serve to completely or partially dehydrate sludge by evaporation which originates from e.g. sewage. The sludge is dried with addition of heat in a drying chamber (2), the sludge being transported on an endless travelling grate (3) from an inlet opening (8) in the drying chamber (2) to a discharge opening (9) in it. The sludge is deposited on the grate in a plurality of juxtaposed sludge strings (18) by means of an extruder (6), in which the sludge is preheated to almost 100.degree. C. prior to extrusion. The extruded strings (18) are then heated with such an intensity that the water in the sludge immediately begins to boil, and that a zone of preferably saturated water steam is formed at any rate in the immediate vicinity of the sludge. This provides a light and porous, dried sludge product which is in no way either burnt or scorched, and which constitutes excellent fuel as well as excellent compost.
