发汗是石蜡精制过程的一个关键。利用发汗皿发汗的加热法除有热水循环加热外,还采用热空气加热或加热壁管加热二种方法,石油一厂的发汗设备两种方法都有。热空气加热法是利用一台抽风机抽出发汗室中的空气,经过蒸汽加热管加热后再送回发汗室进行循环加热,使发汗室空气温度逐渐升高。加热壁管法是利用发汗室两壁的加热蒸汽管加热空气。我厂西炼制车间在党支部正确的领导下,创造了一种明汽发 Sweating is a key ingredient in paraffin refining. The use of sweating dish sweating heating method in addition to hot water circulation heating, but also the use of hot air heating or heating wall tube two methods, a plant of oil sweating equipment have two methods. Hot air heating method is to use a suction fan to sweat out the air in the sweat chamber, heated by the steam heating tube and then sent back to the sweat chamber for cyclic heating, so that the sweat chamber air temperature gradually increased. Heating wall tube method is the use of sweat chamber wall heating steam tube heating air. Our plant West refining workshop under the correct leadership of the party branch, to create a Mingfa
