Description

Известны различные способы очистки от пыли и охлаждени  гор чих газов, например в мокрых циклонах, скрубберах и т. п.Various methods are known for cleaning from dust and cooling hot gases, for example, in wet cyclones, scrubbers, etc.

Предлагаетс  пропускать гор чий запылеиный газ через кип щий слой частиц, непрерывно орошаемый с помощью форсунок водой с последующим удалением агломератов. При этом происходит одновременное охлаждение газа до температуры 80-100°.It is proposed to pass a hot dusty gas through a fluidized bed of particles, continuously irrigated with water nozzles with subsequent removal of agglomerates. When this occurs, the simultaneous cooling of the gas to a temperature of 80-100 °.

Предлагаемый способ осуществл етс  с помощью устройства, описанного в авт. св. jVo 144825.The proposed method is carried out using the device described in ed. St. jVo 144825.

Гор чий запыленный газ подаетс  в устройство снизу через распределительную решетку в кип щий слой частиц размером 0,1-0,5 мм и влажностью 2-4%. который с помощью форсунок иепрерывпо орошаетс  водой. При прохождении через кип щий слой газ охлаждаетс  до температуры 80-100, а частицы пыли увлажн ютс  и агломерируют р-гли слипаютс  с частицами кип п его сло , в результате чего происходит очистка газа от пыли. Очищенный и охлажденный газ выводитс  из верхней части аппарата, а уловленна  пыль в виде прочных влажных гранул отбираетс  непосредственно из кип щего сло .Hot dusty gas is fed into the device from the bottom through a distribution grid in the fluidized bed of particles with a size of 0.1-0.5 mm and a humidity of 2-4%. which, by means of nozzles, is continuously irrigated with water. When passing through the fluidized bed, the gas is cooled to a temperature of 80-100, and the dust particles moisten and agglomerate the p-gly stick together with the particles of the bale of its bed, resulting in the purification of gas from dust. The purified and cooled gas is removed from the upper part of the apparatus, and the trapped dust in the form of strong, moist granules is taken directly from the fluidized bed.

Кип щий слой частиц до пуска установки готов т агломерацией частиц улавливаемой пыли и увлажнением их до влажности 2-4% с пропусканием через кип щий слой воздуха.The fluid bed of particles before the start-up of the installation is prepared by agglomerating the particles collected by the dust and moistening them to a moisture content of 2–4% with passing air through the boiling bed.

При работе устройства, используемого дл  осуществлени  предлагаемого способа, гранулометрический состав частиц сло  и их влажность принимают определенное значение, завис щее от интенсивности перемещивани  (кипени ), температуры газа и количества поданной жидкости , чем больше подаетс  воды в кип щий слой, тем выше влажность частиц и ниже температура отход щих газов. Влалсность частиц кип щего сло  не должна превышать 3-4%, так как при более высокой влажности при скорости газа 0,5-0,7 м1сек кипение частиц прекращаетс . В то же врем , чем выше влажность частиц, тем больше степень улавливани  пыли. Так, проскок пыли при влажности сло  в 3-4% составл ет не более 5-10%, а при влажности 1-2% - 15-20%.When operating the device used to implement the proposed method, the particle size distribution of the bed particles and their humidity take on a certain value, depending on the intensity of displacement (boiling), gas temperature and amount of liquid supplied, the more water is supplied to the fluidized bed, the higher the humidity of the particles and lower exhaust gas temperature. The intensity of the particles of the fluidized bed should not exceed 3-4%, since at higher humidity at a gas velocity of 0.5-0.7 m1s the boiling of the particles ceases. At the same time, the higher the humidity of the particles, the greater the degree of dust collection. Thus, dust slippage at a moisture level of 3-4% is no more than 5-10%, and at a moisture content of 1-2% - 15-20%.

№ 144824-2Если степень улавливани  пыли предлагаемым способом недостаточна , охлажденный газ в дальнейшем подают в какой-либо другой пылеуловитель известной конструкции: рукавный фильтр, скруббер ВТИ, мокрый циклон и т. д.No. 144824-2If the degree of dust capture by the proposed method is insufficient, the cooled gas is subsequently fed to some other dust collector of a known construction: a bag filter, a VTI scrubber, a wet cyclone, etc.

Предлагаемый способ может найти применение в услови х, когда не требуетс  утилизации тепла охлаждаемых газов.The proposed method can be used in conditions where the heat recovery of the cooled gases is not required.
