新型消暖雾催化剂与传统吸湿性催化剂消雾性能的室内对比试验

为了研究一种新的环保型消暖雾催化剂RC／XW的消雾性能，同时选取无水氯化钙（CaCl2）和氯化钠（NaCl）2种吸湿性物质作为对比物，对它们进行室内试验研究。其中RC／XW粒子直径主要集中在12um；将无水氯化钙和氯化钠分别粉碎成10um、15um、20um和30um4个不同的直径。结果表明：不同种类的催化剂、同种类不同尺度的催化剂之间消雾效果都存在很大差异。消雾效果与播撒剂量直接相关。RC／XW适用于消除含水量在0．3g·m^-3以上的严重影响视程的暖雾，且播撒剂量要〉1g·m^-3。

Experiment on the Capability of a New Warm Fog Dissipation Agent in the Laboratory

The main aim of the paper is to study the capability of a new environment protection agent called RC/XW which can dissipate warm fog. We chose anhydrous calcium chloride and sodium chloride as the contrast, the experiment on the capability of the three kinds of agents was done under the same condition in the laboratory. The peak particle diameter of RC/XW is 12 um, and the anhydrous calcium chloride and sodium chloride particles were crushed into four different scales： 10 um, 15 um, 20 um and 30 um. The conclusions are as follows ： There is a very big difference in the fog dissipation effects for different kinds of agents or the same kind of agent with different scales. The fog dissipation effect of agent is directly relative to its seeding dosage. The RC/XW is suitable to warm fog where water content is more than 0.3 g · m^-3, and the seeding dosage must be bigger than 1 g · m^-3.
