Влияние статического электричества

Влияние статического электричества на устойчивость процесса.
Величина возникающих зарядов статического электричества в некоторых случаях достаточна для возникновения мощного электрического разряда, который может послужить производственным источником зажигания при возникновении пожара.
Искры удара и трения, разряды статического электричества вызывают воспламенение частиц пыли, которые затем транспортерными устройствами переносятся в фильтры и бункеры, способствуя возникновению процессов тления или пламенного горения.
Если измельченные вещества являются горючими, то существует вероятность зажигания аэрозолей или пылевых отложений разрядами статического электричества.
Наиболее распространенный способ борьбы со статическим электричеством — заземление оборудования.
Оборудование, выполненное из электропроводящих материалов, не нуждается в защите от статического электричества, если минимальная энергия зажигания перерабатываемого в нем дисперсного вещества превышает 100 мДж.
В промышленности накоплен достаточно большой опыт борьбы с опасными проявлениями статического электричества.
К эффективным мерам обеспечения электростатической искробезопасности относятся: снижение удельного сопротивления перерабатываемых материалов антистатическими добавками, применение электропроводных покрытий, увлажнение воздуха, использование нейтрализаторов статического электричества.
В этих случаях заземление, предназначенное для отвода зарядов статического электричества, становится неэффективным.
Возможными источниками зажигания в системах пневмотранспорта являются разряды статического электричества, искры удара и трения, самовозгорание пылевых отложений.
Помимо разрядов статического электричества возможными источниками зажигания в пневмотранспортных системах могут быть искры удара и трения при попадании внутрь оборудования металлических предметов или теплота трения.
Наиболее вероятные источники зажигания в пылеуловителях — разряды статического электричества, искры или раскаленные частицы, поступившие из оборудования, через которое прошел поток.
