基于循环冷却水旁路净化含油水的模拟装置,研究了旁路流速、各次料水比、旁路吸附塔填料换料时间间隔、吸附塔填料填装形式、系统温度对系统含油水浓度达标时间的影响。结果表明:净化达标时间随旁路流速的增加呈先减少后增加趋势,旁路流速为1.68×10-3m/s时,净化达标时间最短;选择适当的各次料水比1/2 400,保证较短的净化达标时间和较低的经济成本;换料时间间隔为△tn+1=1.2nh时,较其他方式更有效合理;吸油填料的填装形式为混合式,系统运行温度为35℃时,净化达标时间最短。
Based on the simulation device for purifying oil-containing water by circulating cooling water, the effects of the bypass flow rate, the ratio of each material to water, the time interval of refueling of the bypass adsorption tower, the filling form of the packing for the adsorption tower and the system temperature on the concentration of oil- The impact of time. The results showed that the purifying standard time first decreased and then increased with the increase of the bypass flow rate. When the bypass flow rate was 1.68 × 10-3m / s, the purifying time was the shortest. When the appropriate feed water ratio was 1/2 400, Ensure the short purification time and lower economic cost. The time interval of refueling is △ tn + 1 = 1.2nh, which is more effective and reasonable than other methods. The packing form of oil-absorbing filler is mixed, and the system operating temperature is 35 ℃, the shortest time to purify the standard.
