  • Patent number: 8999072
    Abstract: Disclosed are methods and apparatus for cleaning heat exchangers and similar vessels by introducing chemical cleaning solutions and/or solvents while maintaining a target temperature range by direct steam injection into the cleaning solution. The steam may be injected directly into the heat exchanger or into a temporary side stream loop for recirculating the cleaning solution or admixed with fluids being injected to the heat exchanger. The disclosed methods are suitable for removing metallic oxides from a heat exchanger under chemically reducing conditions or metallic species such as copper under chemically oxidizing conditions. In order to further enhance the heat transfer efficiency of heating cleaning solvents by direct steam injection, mixing on the secondary side of the heat exchanger can be enhanced by gas sparging or by transferring liquid between heat exchangers when more than one heat exchanger is being cleaned at the same time.

  • Patent number: 6833032
    Abstract: An automatic deliming process for a steam oven cooker is described. The process initiates a deliming procedure after a predetermined time of normal operation, which period of time is determined by the hardness of the water in the local area. Upon the expiration of this period of time a microprocessor signals an operator to shut down normal operation of the oven, and initiate the deliming process. The microprocessor then activates a peristaltic pump which injects a predetermined quantity of deliming liquid from an external reservoir into the generator. After the deliming time has passed and the generator contents have cooled to 140° F. the microprocessor automatically activates a drain pump to drain the deliming solution from the generator. Subsequently the microprocessor activates a fill-solenoid opening and inlet from a reservoir of rinse water into the generator to rinse the same. The microprocessor then again opens the drain to drain the rinse water, and normal operation is resumed.

  • Publication number: 20040168712
    Abstract: This invention is a method for cleaning a semiconductor manufacturing system, which passes a highly volatile liquid agent through the system to remove the impurities and to dissolve chemicals used in the system. The cleaning agent dissolves and washes the chemicals out of the system to keep the chemicals from combining with moisture in the air and forming oxide particles. By washing with a liquid, residual gases and impurities in the system are rapidly removed from the system. After washing the system, the cleaning agent is quickly dried because the cleaning agent is highly volatile. Thereby, the system is cleaned efficiently within a short time by using this method.

  • Patent number: 6598805
    Abstract: A gas mixture of dry steam and nitrogen gas serving as carrier gas is blown into a hot water mist injection port for rendering the nitrogen gas serve as a medium absorbing latent heat of condensation, thereby smoothly progressing condensation of water vapor and efficiently forming hot water mist. The water vapor is condensed in the hot water mist injection port formed by a cylindrical pipe for supplying latent heat of condensation to the nitrogen gas and dilating the same, thereby accelerating the flow of the hot water mist and spraying the hot water mist to a substrate from the hot water mist injection port at a high speed. Small droplets contained in the high-speed hot water mist have high kinetic energy and high thermal energy, for exhibiting a large colliding effect and a high activation effect with respect to small contaminants adhering to the substrate. A substrate cleaning apparatus capable of spraying hot water mist attaining a high cleaning effect to a substrate is provided.

  • Patent number: 6348174
    Abstract: Infectious wastes originating in hospitals or other locations are deposited into a sealable, pressure resistant, portable sterilizer vessel at the source of the wastes. The sterilizer vessel rides on wheels enabling travel of the filled vessel to a sterilization station at another location where steam is directed into the vessel to perform the sterilization. Operators need not transfer unprocessed infectious waste from a collection cart to a fixed sterilization vessel at the sterilization site. In the preferred form, handler exposure to unprocessed wastes is further reduced by creating an airflow from the vessel opening to a filter while the vessel is opened for deposit of wastes.
