在江南的春天,空气湿度很大,经空压机压缩就会出现不少水珠,它们随着压缩空气被导入雾化室,从而使样品稀释,造成分析结果偏低。一股分析室都没有空调设备,因而一到霉雨季节,只好用勤换硅胶、电炉烘烤房间等办法来降低空气湿度。然而既麻烦、奏效也甚微。为解决这一矛盾,我们在空压机的压缩空气出口之处,加上一只自制的气水分离器(见图)。外壳用镀锌铁皮制成,蛇形冷凝管采用2米长的10毫米紫铜管弯制而成。使用时,关闭闸阀5,打开自来水,再开启空压机。压缩后的空气在铜管内被水冷却,凝集后落入锥形部分,这样,气、水得以分离。测试完毕,将闸阀5打开,放出积存的水。
In the spring of Jiangnan, there is a lot of humidity in the air. A lot of water droplets will appear when compressed by the air compressor. As they are introduced into the atomization chamber with the compressed air, the sample is diluted and the analysis result is low. An analysis room does not have air-conditioning equipment, so a rainy season, had to change frequently with silica gel, electric furnace baking room and other ways to reduce air humidity. However, both cumbersome and ineffective. In order to solve this contradiction, we add a self-made air-water separator at the compressed air outlet of the air compressor (see picture). Shell made of galvanized sheet metal, snake-shaped condenser with 2-meter-long 10 millimeters of red copper bend made. When used, close the valve 5, open the tap water, then turn on the air compressor. The compressed air is cooled by water in the copper tube and falls into the conical section after being condensed, so that the gas and water are separated. Test is completed, the valve 5 open, release the accumulated water.
