我铅锌矿西台化矿鼓风炉过去是用水冷却,所用的冷却水是硬水(总硬度为3.54毫克当量/升)。为了减少结垢,延长水套寿命,采用小温差大水量的方法,水套出水温度仅40～50℃。这就带来耗水量大、热损失大、焦耗高、炉温低、床能力低等一系列问题。为了提高鼓风炉的生产能力,决定采用汽化冷却技术。一九七五年十一月起组织力量,从讨论方案、参观考察、设计到制作安装工程(见图)完工,仅用了半年多时间。一九七六年七月一次试车成功。经过投产以来的实践,证明这项设计是正确的,制作安装的质量是高的,运行情况也是良好的。汽化冷却主要技术参数为:
My Lead-Zinc Mine The Xitaihua blast furnace used to be water-cooled. The cooling water used was hard water (a total hardness of 3.54 meq / l). In order to reduce scaling, extend the life of the water jacket, the use of small temperature difference between the large amount of water, water jacket outlet temperature is only 40 ~ 50 ℃. This brings a series of problems such as large water consumption, large heat loss, high coke consumption, low temperature and low bed capacity. In order to improve the production capacity of the blast furnace, decided to use vaporization cooling technology. Since November 1975, it has taken more than half a year to organize its forces, from discussing plans, visiting and inspecting, designing to making and installing works (see photo). In July 1976 a test drive was successful. The practice since commissioning proves that the design is correct, the quality of the production and installation is high, and the operation is good. The main technical parameters of vaporization cooling:
