Document Type and Number:
WIPO Patent Application WO/2021/140656
Kind Code:
A1
Abstract:
The present invention provides a decontamination system that is capable of continuously inactivating small volumes of microbe- and/or virus-containing waste fluid by heating. The decontamination system 100 for microbe- and/or virus-containing waste fluid comprises: a waste fluid receiving tank 1; a boiler 20; a heat exchange device 10 that heats waste fluid supplied from the waste fluid receiving tank 1, by exchanging heat with the steam from the boiler 20; a waste fluid supply system opening/closing valve 5 and a pump 6 that supply waste fluid to the heat exchange device 10 from the waste fluid receiving tank 1; and a control device 90 that controls the waste fluid receiving tank 1, the boiler 20, the heat exchange device 10, the waste fluid supply system opening/closing valve 5, and the pump 6 and continuously inactivates the waste fluid. The heat exchange device 10 has: a heater 11 that has a coiled tube-type heat exchanger and heats the waste fluid to at least a prescribed first temperature by exchanging heat with the steam; and a holder 13 that has a coiled tube-type heat exchanger and holds the waste fluid that has been heated to at least the first temperature by the heater, at least the first temperature for a prescribed time period, while exchanging heat with the steam.
