吹吸式通风装置具有各种性能,如以通风性能来分类,有以下几种: 1.吹吸式局部通风装置,即装在有局部放散有害气体、蒸气和粉尘等地方的吹吸式通风设备。 2.吹吸式单向均流通风装置,即一面供给工人以新鲜空气,一面又排除有害气体、蒸气和粉尘的吹吸式通风设备。 3.吹吸式隔断装置,即把有害气体、蒸气和粉尘、高温等与工人隔开的通风设备。一、吹吸式通风装置的基本设计公式
Blow-and-breathers have a variety of properties, such as classification by ventilation performance, in the following categories: 1. Blow-and-suction local-ventilation devices, ie, blow-and-suction ventilation in places with localized emission of harmful gases, vapors, and dust. equipment. 2. Blow-and-suction one-way flow equalization ventilation device, which is a blowing and sucking type ventilation device that supplies fresh air to workers and excludes harmful gases, vapors and dust. 3. Blow-and-suction partitions, ie, ventilation equipment that separates hazardous gases, vapors, dust, and high temperatures from workers. First, the basic design formula of blowing ventilation device
