(54) СПОСОБ АВТОМАТИЧЕСКОГО УПРАВЛЕНИЯ ПРОЦЕССОМ ПОЛУЧЕНИЯ ПЕЧНОГО ГАЗА(54) METHOD FOR AUTOMATIC CONTROL OF THE HEATING GAS PRODUCTION PROCESS
1one
Изобретение относитс к способу автоматического управлени процессом получени печного газа в производстве серной кислоты.The invention relates to a method for automatically controlling the process of producing furnace gas in the production of sulfuric acid.
Известен способ автоматического управлени процессом получени печного газа в производстве серной кислоты путем регулировани расхода воздуха в печи и расхода газа перед контактными аппаратами. Ол,нако такой способ имеет повышенные потери серы из-за отсутстви автоматической обратной св зи между печным и контактным отделени ми и продолжительных переходных процессов при изменении технологического режима контактного отделени .There is a known method of automatically controlling the process of producing furnace gas in the production of sulfuric acid by controlling the air flow in the furnace and the gas flow before the contact devices. Ol, however, this method has increased sulfur loss due to the lack of automatic feedback between the furnace and contact compartments and prolonged transients when the technological mode of the contact compartment changes.
Цель изобретени - уменьшение потерь серы .The purpose of the invention is to reduce the loss of sulfur.
Это достигаетс тем, что при регулировании расхода воздуха в печь ввод т коррекцию по давлению разрежени в общем коллекторе газа .This is achieved by adjusting the vacuum pressure in the common gas manifold to regulate the flow of air into the furnace.
На чертеже показана блок-схема, реализуюша способ.The drawing shows a flowchart implementing the method.
Печной газ после печи 1 кип щего сло , нормальный технологический режим в которой поддерживаетс при помощи воздуходувки 2, проходит котел-утилизатор :3, циклон 4, электрофильтр 5 и поступает в общий коллектор 6 газа, откуда он компрессором 7 отбираетс в контактное отделение. Нагрузка контактного отделени 8 измен етс в зависимости от качества получаемого газа при помощи задатчика 9 регул тора 10 расхода газа.The furnace gas after the fluidized bed furnace 1, the normal process mode in which is maintained by means of blower 2, passes the waste heat boiler: 3, cyclone 4, electrostatic precipitator 5 and enters the common gas collector 6, from where it is taken by the compressor 7 to the contact compartment. The load of the contact compartment 8 varies depending on the quality of the produced gas using the setpoint 9 of the gas flow controller 10.
Изменение потреблени газа контактным отделением влечет за собой изменение режима в коллекторе газа, что отслеживаетс главным регул тором 11 двухконтурной системы автоматического регулировани . Этот регул тор корректирует работу вспомогательных регул торов 12 расхода воздуха таким образом, чтобы расход образующегос обжигового газа стал равен потреблению.The change in gas consumption by the contact compartment entails a change in mode in the gas collector, which is monitored by the main controller 11 of the dual-circuit automatic control system. This regulator adjusts the operation of the auxiliary regulators 12 of the air flow so that the flow rate of the resulting kiln gas becomes equal to the consumption.
