Изобретение относитс  к способам определени  запыленности газов и может примен тьс  в системах автоматического регулировани  аспирации и технологических процессов.The invention relates to methods for determining the dust content of gases and can be used in systems for automatic control of aspiration and technological processes.

Известен способ определени  запыленности воздуха путем пропускани  его через фильтр и замера количества пыли на фильтре.There is a known method for determining the dust content of air by passing it through a filter and measuring the amount of dust on the filter.

Недостатком известного способа  вл етс  то, что он не обеспечивает надежного и эффективного процесса определени  запыленности воздуха.The disadvantage of this method is that it does not provide a reliable and efficient process for determining the dust content of the air.

По предлагаемому способу измер ют врем  осаждени  заданного количества пыли, определ емого путем сравнени  величины перепада давлени  на фильтре и на диафрагме, установленной после фильтра, и по этому времени суд т о концентрации пыли в воздухе. Это позвол ет упростить процесс и повысить его эффективность.According to the proposed method, the time of deposition of a given amount of dust, determined by comparing the pressure drop across the filter and the diaphragm installed after the filter, is measured, and the dust concentration in the air is judged from this time. This simplifies the process and improves its efficiency.

На чертеже показана схема реализации описываемого способа.The drawing shows the implementation of the described method.

Способ осуществл ют следующим образом.The method is carried out as follows.

С начала Включени  системы / прокачки воздуха через фильтрующий элемент 2 и последовательно соединенную с ним диафрагму 3 измер етс  врем  опыта и величина перепада давлений на фильтрующем элементе и диафрагме . Обе величины перепадов давлени , замеренные дифманометрами 4 и 5, сравниваютс  в элементе сравнени  6. ПолученныйFrom the beginning of switching on the system / pumping air through the filter element 2 and the diaphragm 3 connected in series with it, the test time and the pressure drop across the filter element and diaphragm are measured. Both values of pressure drops measured by gauges 4 and 5 are compared in the element of comparison 6. The resulting

сигнал поступает в усилитель 7 с микропереключателем , посто нный выходной сигнал которого направл етс  в интегрирующий блок измерител  8 времени.The signal enters the amplifier 7 with a microswitch, the constant output of which is directed to the integrating unit of the time meter 8.

Измерение времени продолжаетс  до тех пор, пока растущий по мере отложени  пыли перепад давлени  на фильтрующем элементе 2 не станет равным перепаду давлени  на диафрагме 3. При этом выходной сигнал усилител  7 прекращаетс , а угол поворота вала измерител  8 времени, пропорциональный времени отложени  пыли на фильтрующем элементе , при помощи нелинейного функционального преобразовател  превращаетс  в сигнал,The time measurement continues until the pressure differential on filter element 2 that grows as dust accumulates becomes equal to the pressure difference on diaphragm 3. The output signal of amplifier 7 stops and the angle of rotation of the meter 8 is proportional to the time of dust deposition on the filter element using a non-linear functional converter is converted into a signal

пропорциональный средней концентрации пыли за врем  измерени .proportional to the average dust concentration during the measurement.

Предмет изобретени Subject invention

Способ определени  запыленности воздуха путем прокачивани  с посто нной скоростью воздуха через фильтр и замера количества пыли на фильтре, отличающийс  тем, что, с целью упрощени  и повыщени  эффективности процесса, измер ют врем  осаждени  заданного количества пыли, определ емого путем сравнени  величин перепада давлени  на фильтре и на диафрагме, установленной после фильтра, и по этому времени суд т о концентрации пыли в воздухе.Method for determining air dustiness by pumping air at a constant speed through a filter and measuring the amount of dust on the filter, characterized in that, in order to simplify and increase the efficiency of the process, the time of deposition of a given amount of dust, measured by comparing the pressure drop across the filter, is measured and on the diaphragm installed after the filter, and from this time the concentration of dust in the air is judged.
