Description
Известен способ определени количества угольной пыли в газе-носителе после пылеулавливающей апиаратуры с измерением расхода газа-носител и отбором проб угольной пыли.There is a known method for determining the amount of coal dust in a carrier gas after a dust collecting device with measuring the flow rate of the carrier gas and sampling of coal dust.
Предложенный способ отличаетс тем, что измер ют зольность исходного угл и угольной пыли в газе-носителе после нылеуловите.т и по изменению зольности суд т о количестве угольной пыли.The proposed method is characterized in that the ash content of the original coal and coal dust in the carrier gas is measured after a sample and the amount of coal dust is judged by the change in the ash content.
Это позвол ет упросгить известный способ анализа.This allows us to simplify the known method of analysis.
Сущность предложенного способа состоит в использовании изменени показателей свойств угл при разделении газовзвеси на твердую и газообразную фазы. Уносима газом после пылеуловител угольна пыль резко отличаетс по свойствам, в частности по зольности, от перерабатываемого угл , поэтому ири разделении газовзвесн на фазы наблюдаетс сдвиг показателей свойств угл , поступающего на переработку (исходного) и обработанного.The essence of the proposed method consists in using a change in the indicators of the properties of coal in the separation of a gas suspension into a solid and gaseous phase. The coal dust carried by the gas after the dust collector differs sharply in properties, in particular in ash content, from the coal being processed, therefore, when separating gas suspension into phases, there is a shift in the indicators of the properties of the coal supplied for processing (initial) and treated.
По величине этого сдвига с учетом приведенного к сухому весу количества перерабатываемого угл и объема отработанного газа после пылеуловител определ ют запыленность газа.The dust content of the gas is determined by the magnitude of this shift, taking into account the amount of coal processed to the dry weight and the volume of exhaust gas after the dust collector.
Предмет изобретени Subject invention
Способ определени количества угольной пыли в газе-носителе после пылеулавливающей аппаратуры с измерением расхода газаносител п отбором проб угольной пыли, отличающийс тем, что, с целью упрощени определени , измер ют зольность исходного угл и угольной пыли в газе-носителе после пылеуловител и по изменению зольности суд т о количестве угольной пыли.The method of determining the amount of coal dust in the carrier gas after the dust collecting equipment with measuring the flow rate of the gas carrier and sampling of coal dust, characterized in that, to simplify the determination, the ash content of the original coal and coal dust in the carrier gas after the dust collector is measured and the ash content is changed judge about the amount of coal dust.
