摘要： Vaporized hydrogen peroxide is used for decontamination of enclosed and sealed areas. It is capable of destroying all forms of microbial life. It is commonly produced from a solution of liquid H2O2 and water, by means of generators specifically designed for the purpose. The present invention provides a combined source for heating steam and vaporized hydrogen peroxide and a method for simultaneously supplying steam and vaporized hydrogen peroxide. A device according to the invention comprises a chamber adapted for receiving water through an inlet and expelling steam through an outlet. A vessel for receiving and vaporizing hydrogen peroxide solution is provided in close contact with the chamber. Heat from the water vapor in the chamber is allowed to supply the required energy for producing hydrogen peroxide vapor in the vessel from an aqueous solution.

摘要： According to the present invention a method for heat recovery in a device for the sterilization of biological material is provided. The present method eliminates the risk of contaminating the sterilized effluent with unsterilized biological material via the heat recovery system. In a device according to the invention, a heat recovery circuit is provided for transferring heat from the sterilized effluent stream to the biologically hazardous feed stream. Protection against contamination through leaks is obtained by maintaining at all times a pressure difference preventing biologically hazardous material from bypassing the heat treatment and flowing in the direction of the sterilized material.

摘要： A method for cooling a jacketed autoclave or steam sterilizer by allowing a film of water to flow down as inner wall of the sterilizer's jacket. Condensate from the jacket space is drawn into a water ring pump. The water ring pump draws condensate from the lowest point of the jacket to a water side of the pump, and gas from the jacket to a normal suction inlet of the pump. During the process of cooling the sterilizer, a stream of water and air from the water ring pump is conducted to an upper part of the jacket of the steam sterilizer and is allowed to flow as a film down the inner wall of the jacket. Evaporation of the water is enhanced by lowering the pressure in the jacket.

摘要： A device in which exhaust fluid from a facility or equipment for treating biologically active material is heated to a temperature of at least 400° C. to kill or denature hazardous agents, and conveyed through a metal filter with no more than 0.1 μm pore size, which is heated, preferably by the fluid, to essentially the same temperature. The relevant temperature is maintained during operation in both the fluid and the filter. Since the filter is dimensioned to trap microbial agents like bacteria and viruses and the temperature of the filter surfaces is sufficient for sterilization, microbial agents are bound to come into contact with said surfaces and a very high degree of sterilization certainty is reached. The filter is welded to the device body to provide a seamless structure. Heating and filtration are both alone sufficient for removing biohazardous agents, so the device provides double security.

摘要： In a multi-effect falling-film evaporator, purified water for special purposes is produced. In each effect, a steam phase and a water phase is produced from the feed water. The steam phase is used for heating in the subsequent effect, whereby it condenses to product water, and the water phase becomes the feed stream for the subsequent effect. A reject stream is removed from the process to carry off impurities separated from the water. According to the invention, a reject stream is removed from each effect. Preferably, each reject stream is a condensed fraction of the steam generated in the respective effect.
