Abstract: Настоящее изобретение относится к вытяжному вентилятору, предназначенному для воздухообмена в здании, в частности для жилья или непроизводственного здания. Вытяжной воздушный вентилятор, предназначенный для размещения на здании на выходе вентиляционного контура, имеющий нормальный выпускной проход для выпуска воздуха наружу, при этом содержит деформируемую часть, закрывающую проход наружу и выполненную с возможностью температурной деформации во время пожара под действием расхода горячих газов в вентиляторе, таким образом, чтобы образовать выпускной проход, дополнительный к нормальному выпускному проходу с увеличением полного сечения прохода наружу. Преимущество заключается в том, что в случае пожара в здании прохождение воздуха или дымовых газов с более высокой температурой в указанном вентиляторе сопровождается нагревом деформируемой части, которая, деформируясь, автоматически увеличивает проходное сечение для выпуска наружу дымовых газов и уменьшает потерю давления потока, что улучшает расход. Можно, в частности, компенсировать потерю давления, обусловленную остановкой вытяжной турбины, в том случае, если установка содержит последнюю. При этом облегчается естественный выпуск горячих газов в помещении наружу. 8 з.п. ф-лы, 6 ил.

Granted: 2021-11-23
Abstract: FIELD: exhaust gas purification. 
     SUBSTANCE: present invention relates to a method and system for the recovery of emission solid particles and nitrogen oxides (NOx) from waste and flue gases. Flue gas is passed through one or more ceramic filters catalyzed by a selective catalytic reduction catalyst of nitrogen oxides in the presence of ammonia added to flue gas either as such or in the form of its precursor. At a temperature below 250°C, waste gas containing nitrogen dioxide is introduced into flue gas in front of one or more ceramic filters. Waste gas containing nitrogen dioxide is produced by catalytic oxidation of ammonia or its precursor by oxygen-containing atmosphere to waste gas containing nitrogen monoxide and oxygen in the presence of an oxidation catalyst. Next, waste gas is cooled to ambient temperature (from -20 to +40°C), and nitrogen monoxide is oxidized in cooled waste gas to waste gas containing nitrogen dioxide. Waste gas containing nitrogen dioxide is introduced into flue gas in the amount that leads to the fact that from 45 to 55 vol.% of nitrogen oxides are nitrogen dioxide at the entrance to the selective catalytic reduction catalyst of nitrogen oxides.  
     EFFECT: increasing the efficiency of SCR catalyst at a gas temperature below 250°C.
