最近日本东京的气幕公司利用龙卷风的定向吸气性,开发了远方排气装置“卷风机”,并已开始出售。对于工厂等产生的有害气体和粉尘,可以高效率地捕捉并排出到远处。以前的吸尘罩由于吸气没有完全的定向性,一离开吸气口,吸入的风速便很快衰减,因此只能在有害气体及粉尘的发生源附近设置吸尘罩;而且,除发生的有害气体和粉尘之外,还同时从四周吸入大量的空气,
Recently, the air curtain company in Tokyo, Japan, used the directional suction performance of a tornado to develop a remote exhaust “blower” and started selling it. Harmful gases and dust generated in factories, etc. can be efficiently captured and discharged to distant locations. Previous suction hoods are not completely directional due to inhalation. Once they leave the suction port, the inhaled wind speed decays rapidly. Therefore, dust suction hoods can only be installed near the source of harmful gases and dust; and, in addition, In addition to harmful gases and dust, it also inhales a lot of air from the surroundings.
