Description
Изобретение относитс к управлению процессом очистки отход щих газов цветной металлургии в электрофильтрах и может быть использовано на предпри ти х цветной металлургии , отход щие газы которых используютс дл производства серной кислоты. Известен способ управлени процессом очистки газов в электрофильтре путем изменени напр жени на электродах по искровым и дуговым разр дам. Однако эффективность очистки газов по известному способу низка , вследствие этого к.п.д. установки мал. С целью устранени указанных недостатков напр жение измен ют в зависимости от температуры , расхода и химического состава очищаемого газа. На чертеже представлена блок-схема устройства , реализующего этот способ. Устройство работает следующим образом. Газ по магистрали 1 направл етс в фильтр 2, содержащий коронирующий 3 и осадительный 4 электроды. Регулирование напр жени на электродах на максимально возможном Значении, близком к пробойному, что соответствует наилучщему режиму очистки газа, осуществл етс регул тором 5. Последний получает ииформацию об объекте при помощи реле минимального напр жени 6 и реле максимального тока 7 через устройство обратной св зи 8 и блок управлени 9. Ключ 10 при нормальной работе фильтра установлен в положение «А. Регул тор 5 измен ет напр жение на электродах 3 и 4 при помощи магнитного усилител 11, включенного последовательно с управл ющим трансформатором 12 и первичной обмоткой повышающего трансформатора 13, который позвол ет за счет изменени индукции регулировать напр жение питани фильтра 2. При очистке газа, резко измеи ющего состав , или из-за изменени характеристик технологического оборудовани фильтра, увеличени напр жени вследствие сокращени рассто ни между электродами в результате налипани на них частиц пыли может возникнуть пробой, который фиксируетс устройством 14. Сигнал о пробое поступает в вычислительиое устройство 15, которое переключает ключ 10 в положение «Б, дает сигнал на быстрое снижение напр жени на электродах и на основании информации, предшествующей пробою, формирует новое управл ющее воздействие , соответствующее напр жению, близкому к пробойному дл изменившихс условий . Измерение входных параметров газа осуществл етс при помощи датчиков температуры 16, расхода 17 и состава 18.The invention relates to the management of the waste gas cleaning process of non-ferrous metallurgy in electrostatic precipitators and can be used in non-ferrous metallurgy plants whose waste gases are used to produce sulfuric acid. There is a known method for controlling the gas cleaning process in an electrostatic precipitator by varying the voltage on the electrodes with respect to spark and arc discharges. However, the efficiency of gas purification by a known method is low, as a result of this efficiency. installation is small. In order to eliminate these drawbacks, the voltage is changed depending on the temperature, flow rate and chemical composition of the gas to be purified. The drawing shows the block diagram of the device that implements this method. The device works as follows. The gas through line 1 is directed to the filter 2, which contains the corona 3 and precipitating 4 electrodes. Voltage regulation at the electrodes at the maximum possible value, close to the breakdown voltage, which corresponds to the best gas cleaning mode, is performed by the regulator 5. The latter receives information about the object using the minimum voltage relay 6 and the overcurrent relay 7 through feedback device 8 and the control unit 9. The key 10 during normal operation of the filter is set to the position "A. The regulator 5 changes the voltage on the electrodes 3 and 4 using a magnetic amplifier 11 connected in series with the control transformer 12 and the primary winding of the step-up transformer 13, which allows the supply voltage of the filter 2 to be regulated by changing the induction. drastically changing the composition, or due to a change in the characteristics of the filter processing equipment, an increase in voltage due to a reduction in the distance between the electrodes as a result of sticking of dust particles on them the breakdown, which is fixed by the device 14. The breakdown signal enters the calculating device 15, which switches the key 10 to the "B" position, gives a signal for a rapid decrease in the voltage on the electrodes and, on the basis of the information preceding the breakdown, forms a new control action close to the breakdown for altered conditions. Measurement of the input parameters of the gas is carried out using temperature sensors 16, flow 17 and composition 18.
Така работа схемы позвол ет сократить врем выхода фильтра на рабочий режим с максимально возможным напр жением.Such operation of the circuit makes it possible to shorten the time for the filter to reach the operating mode with the highest possible voltage.
