现在工厂用的除尘器一般都是依靠机械或电力的作用。最近据日本人研究,激光也可以除尘。附图是他们提出的一种利用激光除尘的方案。其方法是在含尘气体流过的管道上开一条缝,让红外激光器发出的片状激光射束通过。当含尘气体流经管道时,激光射束能够把尘粒捕捉,使它们向管道外 Dust catchers are now used in factories are generally rely on the role of mechanical or electrical. According to Japanese studies recently, the laser can also dust. The drawings are a proposal of their use of laser dust removal program. The method is to open a slit in the pipe through which the dust-laden gas flows to let the sheet laser beam emitted by the infrared laser pass. When the dust-laden gas flows through the pipe, the laser beam captures the dust particles to the outside of the pipe
