摘要:
The invention relates to a device and a method for the separation of solids from a biowaste slurry before heat treatment, and for heat treatment of the separated solids. The device comprises a chamber with a main inlet port for feeding slurry, and outlet ports. A unit for separating solids is adapted to an outlet port so, that liquid leaving the chamber has passed through the separation unit. A second outlet port is provided directly from the chamber to allow removal, following sterilization, of solids collected in the chamber. The sterilization is secured by temperature monitoring at representative locations.
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.

Cooling of a jacketed autoclave or steam sterilizer is carried out by allowing a film of water to flow down the inner wall of the sterilizer's jacket space. Condensate from the jacket space is drawn into the water ring pump provided for vacuum in the autoclave jacket. The condensate is conducted to the water side of the pump while the normal suction line is connected at the pump to the gas zone. Thus, the water ring pump draws condensate from the lowest point of the jacket to the water side, and gas from the jacket space to the normal suction inlet. During the process of sterilizer cooling, a stream of water and air from the water ring pump is conducted to the upper part of the jacket space of the steam sterilizer and is allowed to flow as a film down the inner wall of the jacket space. Evaporation takes place with cooling of the jacket inner wall. This evaporation is enhanced by the lowering of pressure in the jacket due to the action of the water ring pump. Thus, the autoclave is cooled by a film of water flowing across the jacket inner wall while evaporating.

The invention relates to the sterilization of a load of goods with hydrogen peroxide vapor in a closed space. The method involves a sequence of creating a sub-atmosphelic pressure in a sterilization chamber, introduction of vaporized hydrogen peroxide and the use of a gas circulation device within the sterilization chamber, whereby the output of the gas circulation device is controlled according to the pressure in the sterilization chamber. A uniform and consistent distribution of hydrogen peroxide throughout the load is achieved.
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 H 2 O 2 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. 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.
