(5) СПОСОБ ОЧИСТКИ ГАЗА ОТ ПЫЛИ(5) METHOD FOR CLEANING GAS FROM DUST
II
Изобретение относитс к технике очистки газов от твердых частиц и может быть использовано в энергетике дл очистки дымовых газов от золы, а также в других отрасл х промышленности , где необходима очистка гор чих газов, содержащих в своем составе пары воды или других жидкостей .The invention relates to a technique for purifying gases from solid particles and can be used in the power industry for cleaning flue gases from ash, as well as in other sectors of the industry where it is necessary to purify hot gases containing water vapor or other liquids.
Известен способ очистки газов от пыли путем фильтрации его через слой фильтрующего материала и отвода очищенного газа С11.A known method of cleaning gases from dust by filtering it through a layer of filter material and removal of purified gas C11.
Однако высока степень очистки достигаетс за счет достаточно большого перепада давлений (гидравлйческог .о сопротивлени сло ). Снижение гидравлического сопротивлени путем увеличени крупности наполнител приводит к снижению эффективности улавливани ; снижение скорости фильтрации , когда улавливание роисходит за счет диффузионно-седиментациойного механизма осаждени частиц.However, a high degree of purification is achieved due to a sufficiently large pressure drop (hydraulic resistance layer). A decrease in hydraulic resistance by increasing the size of the filler leads to a decrease in the collection efficiency; a decrease in the filtration rate when trapping occurs due to the diffusion-sedimentation mechanism for the deposition of particles.
приводит к необоснованному увеличе-,. нию габаритов установки. Повышение эффективности очистки газов при орошении фильтрующего материала значи- .: тельно услож н ет конструкцию фильтра.leads to unreasonable increase-. installation dimensions. The increase in the efficiency of gas cleaning during the irrigation of filtering material is significant: it complicates the design of the filter.
Цель изобретени - повышение эффективности улавливани пыли и снижение гидравлического сопротивлени сло ,The purpose of the invention is to increase the efficiency of dust collection and reduce the hydraulic resistance of the layer,
Поставленна цель достигаетс The goal is achieved
10 тем, что согласно способу очистки газа от пыли путем фильтрации его через слой зернистого материала и отвода очищенного газа, фильтрацию ведут при температуре очищенного 10 in that according to the method of cleaning gas from dust by filtering it through a layer of granular material and removing the purified gas, filtering is carried out at the temperature of the purified
IS газа на 5-tO°C ниже температуры точки росы газа оIS gas at 5-tO ° C below the gas dew point temperature o
Способ осуществл етс следующим образом.The method is carried out as follows.
Через фильтрующий слой толщиной Through the filter layer thickness
