在战后的年代里,国外有许多工业部门(黑色和有色冶金部门,化学工业部门等等)都广泛地采用了在快速除尘器[也就是所谓文氏洗涤器]中进行净气除尘的方法。大家知道,这种方法就是把水引入含尘的气流中,气流沿文氏管作高速度的运动,在颈口的速度达60-90公尺/秒。根据管子直径的大小,水一般都在文氏管的颈口[或在它的渐缩管内]以一个地方或几个地方供给之。水压相当高,达4个大气压。在气流高速运动
In the post-war years, many industrial sectors abroad (black and non-ferrous metallurgy, chemical industry, etc.) widely adopted the method of scrubbing gas in a rapid dust collector [also known as a Venturi scrubber] . As we all know, this method is to introduce water into dust-laden airflow that flows along the venturi at a high speed and reaches 60-90 meters / second at the neck. Depending on the diameter of the tube, the water is usually supplied at one or more places on the venturi neck [or in its tapering tube]. Water pressure is quite high up to 4 atmospheres. In the air flow at high speed
