Abstract
1. Способ обеспечения защиты от микробиологического загрязнения и/или дезинфекции/восстановления окружающей среды, где способ включает следующие стадии: (a) генерирования газа, содержащего очищенный газообразный пероксид водорода (PHPG), который, по существу, не содержит гидратной воды, озона, соединений-продуктов плазмы и/или органических соединений; (b) направления PHPG в окружающую среду, чтобы газообразный пероксид водорода выполнял функцию по обеспечению защиты от микробиологического загрязнения и/или дезинфекции/восстановления в окружающей среде, как на поверхностях, так и в воздухе. ! 2. Способ по п.1, в котором образующийся PHPG электростатически притягивается к положительно и отрицательно заряженным структурам и/или местам на микробах, что повышает его эффективность во время защиты от микробиологического загрязнения и/или дезинфекции/восстановления, по сравнению либо с гидратированным пероксидом водорода, либо с озоном. ! 3. Способ по п.1, в котором концентрация образующегося PHPG составляет от 0,005 до 0,10 млн-1. ! 4. Способ по п.1, в котором упомянутые защита от микробиологического загрязнения и/или дезинфекция/восстановление окружающей среды включают очистку воздуха внутри помещений, средство очистки воды, противогрибковое средство, бактерицидное средство и противовирусное средство. ! 5. Способ по п.1, в котором процентная влажность воздуха находится в диапазоне 5-99% или приводится регулированием к данному диапазону. ! 6. Способ обеспечения защиты от микробиологического загрязнения и/или дезинфекции/восстановления окружающей среды, где способ включает следующие стадии: (a) облучения металлического или оксидно-м

2. Способ по п.1, в котором образующийся PHPG электростатически притягивается к положительно и отрицательно заряженным структурам и/или местам на микробах, что повышает его эффективность во время защиты от микробиологического загрязнения и/или дезинфекции/восстановления, по сравнению либо с гидратированным пероксидом водорода, либо с озоном.
3. Способ по п.1, в котором концентрация образующегося PHPG составляет от 0,005 до 0,10 млн-1.
4. Способ по п.1, в котором упомянутые защита от микробиологического загрязнения и/или дезинфекция/восстановление окружающей среды включают очистку воздуха внутри помещений, средство очистки воды, противогрибковое средство, бактерицидное средство и противовирусное средство.
5. Способ по п.1, в котором процентная влажность воздуха находится в диапазоне 5-99% или приводится регулированием к данному диапазону.
6. Способ обеспечения защиты от микробиологического загрязнения и/или дезинфекции/восстановления окружающей среды, где способ включает следующие стадии: (a) облучения металлического или оксидно-металлического катализатора ультрафиолетовым светом в присутствии влажного очищенного окружающего воздуха в таком режиме, чтобы формировать очищенный газообразный пероксид водорода (PHPG), который, по существу, не содержит гидратной воды, озона, соединений-продуктов плазмы и органических соединений; и (b) направления PHPG в окружающую среду, чтобы газообразный пероксид водорода выполнял функцию по обеспечению защиты от инфекций и/или дезинфекции/восстановления в окружающей среде, как на поверхностях, так и в воздухе.
7. Способ по п.6, в котором упомянутые защита от микробиологического загрязнения и/или дезинфекция/восстановление окружающей среды включает очистку воздуха внутри помещений, средство очистки воды, противогрибковое средство, бактерицидное средство и противовирусное средство.
8. Способ по п.6, в котором процентная влажность воздуха находится в диапазоне 5-99% или приводится регулированием к данному диапазону.
9. Способ по п.6, в котором упомянутый металлический или оксидно-металлический катализатор является диоксидом титана.
10. Способ по п.6, в котором упомянутое образование PHPG приводит также к очистке окружающего воздуха как от озона, так и от VOC посредством прямой химической реакции данных соединений с PHPG, при этом упомянутая очистка включает (a) взаимодействие с озоном для образования кислорода и воды, и (b) взаимодействие с VOC для образования диоксида углерода и воды.
11. Диффузорное устройство для образования PHPG, включающее: (a) источник ультрафиолетового света; (b) конструкцию подложки металлического или оксидно-металлического катализатора; и (d) воздухораспределительный механизм.
12. Устройство по п.11, в котором морфология катализатора на его подложке является тонкой, подобной парусу воздухопроницамой конструкцией, расположенной перпендикулярно воздушному потоку через диффузорное устройство; и
при этом упомянутая морфология изменяет равновесие реакции так, чтобы в результате реакции образовывался пероксид водорода как посредством окисления воды, так и посредством восстановления диоксигена; и упомянутая морфология, по существу, предотвращает восстановление пероксида водорода на катализаторе путем принуждения пероксида водорода к быстрому оттоку от катализатора до того, как пероксид водорода может быть восстановлен.
13. Устройство по п.11, в котором упомянутый воздухораспределительный механизм является вентилятором.
14. Устройство по п.11, в котором упомянутый источник ультрафиолетового света генерирует, по меньшей мере, один диапазон длин волн.
15. Устройство по п.11, в котором упомянутый источник ультрафиолетового света генерирует больше, чем один диапазон длин волн.
