Claims (11)

1. Способ для непрерывной стерилизации поверхностей смесью воздуха и газообразной перекиси водорода, при котором поток горячего воздуха подают через подающую трубу на различные поверхности, подлежащие стерилизации, отличающийся тем, что горячий воздух смешивают с полностью испаренной перекисью водорода, причем испаренную перекись водорода получают путем образования тонкой пленки жидкой перекиси водорода в пористой трубе и подогрева ее, при этом пористая труба образует часть трубы, подающей горячий воздух и диффундирующей испаренную перекись водорода в поток горячего воздуха.1. A method for continuous sterilization of surfaces with a mixture of air and gaseous hydrogen peroxide, in which a stream of hot air is supplied through a supply pipe to various surfaces to be sterilized, characterized in that the hot air is mixed with completely vaporized hydrogen peroxide, wherein the vaporized hydrogen peroxide is obtained by forming thin film of liquid hydrogen peroxide in a porous pipe and heating it, while the porous pipe forms part of the pipe that supplies hot air and diffuses the vaporized EREC hydrogen in the hot air stream. 2. Способ по п. 1, отличающийся тем, что испарение перекиси водорода производят при температуре 110 - 130oС подогревающего оборудования, предпочтительно при температуре около 120oС.2. The method according to p. 1, characterized in that the evaporation of hydrogen peroxide is carried out at a temperature of 110 - 130 o With heating equipment, preferably at a temperature of about 120 o C. 3. Способ по пп. 1 или 2, отличающийся тем, что концентрация перекиси водорода составляет 5 - 20 мг/литр воздуха и расход горячего воздуха составляет 20 - 50 л/мин. 3. The method according to PP. 1 or 2, characterized in that the concentration of hydrogen peroxide is 5 to 20 mg / liter of air and the flow rate of hot air is 20 to 50 l / min. 4.

The method according to any one of paragraphs 1-3, characterized in that the entire system is maintained at a temperature of about 120 o C. 5. Способ по любому из пунктов 1-4, отличающийся тем, что концентрацию перекиси водорода оперативно контролируют посредством фотометра или системы, основанной на термическом эффекте каталитического разложения перекиси водорода, в которой отмеренную небольшую часть смеси направляют в фотометр или систему катализа. 5. The method according to any one of paragraphs 1-4, characterized in that the concentration of hydrogen peroxide is promptly controlled by a photometer or system based on the thermal effect of the catalytic decomposition of hydrogen peroxide, in which a measured small portion of the mixture is sent to a photometer or catalysis system. 6. Устройство для непрерывной стерилизации поверхностей в линии, заполненной асептическим веществом, включающее трубу для подачи смеси горячего воздуха и испаренной перекиси водорода, и множество сопел, через которые эта смесь подается на поверхности, подлежащие стерилизации, отличающееся тем, что подающая труба содержит секцию, образованную пористой трубой, для подачи газообразной перекиси водорода непосредственно в поток горячего воздуха, причем пористая труба окружена устройствами для подогрева. 6. Device for continuous sterilization of surfaces in a line filled with aseptic substance, including a pipe for supplying a mixture of hot air and vaporized hydrogen peroxide, and many nozzles through which this mixture is supplied to surfaces to be sterilized, characterized in that the supply pipe contains a section, formed by a porous pipe for supplying gaseous hydrogen peroxide directly to the stream of hot air, the porous pipe being surrounded by heating devices. 7. Устройство по п. 6, отличающееся тем, что пористая труба имеет достаточную длину для обеспечения адекватной скорости потока и испарения перекиси водорода. 7. The device according to p. 6, characterized in that the porous pipe is of sufficient length to provide an adequate flow rate and evaporation of hydrogen peroxide. 8. Устройство по пп. 6 или 7, отличающееся тем, что пористая труба представляет собой металлокерамическую трубу. 8. The device according to paragraphs. 6 or 7, characterized in that the porous pipe is a cermet tube. 9. Устройство по п. 8, отличающееся тем, что металлокерамическая труба имеет поры диаметром 20-80 микрон, предпочтительно порядка 40 микрон. 9. The device according to p. 8, characterized in that the cermet tube has pores with a diameter of 20-80 microns, preferably about 40 microns. 10. Устройство по любому из пунктов 6-9, отличающееся тем, что подающая труба подогревается паром. 10. The device according to any one of paragraphs 6-9, characterized in that the feed pipe is heated by steam. 11. Устройство по любому из пунктов 6 - 10, отличающееся тем, что оно для оперативного режима измерения концентрации перекиси водорода содержит фотометр или систему, основанную на каталитическом разложении перекиси водорода. 11. The device according to any one of paragraphs 6 to 10, characterized in that it for the operational mode of measuring the concentration of hydrogen peroxide contains a photometer or system based on the catalytic decomposition of hydrogen peroxide.
