电石工业作为我国重要的基础化工行业，也是高耗能、高污染的行业。由于电石炉烟气自身的特点，使其净化难度大，大量烟气及粉尘带来了严重的环境问题。将电石炉高温烟气作为石灰煅烧的燃料，再将石灰窑产生的烟气用于焦炭干燥，然后将烘干后的废气引出，作为助燃空气直接用管道输送至自备电厂，在利用热烟气中的显热的同时，在锅炉中通过燃烧去除烟气中的大部分污染物，随后烟气进入污染物控制系统中，将其中的污染物去除后排放，可使电石行业大气污染物达到趋零排放。

As the basic chemical industry in China, calcium carbide industry is a high energy-consuming and high polluting industry.Due to its characteristics of the waste gas of calcium carbide furnace, it is difficult to be purified and thus the huge amount of gases and dusts has brought about serious environmental problems.It was illustrated that the high-temperature waste gas from the calcium carbide furnace was passed into the lime kiln as flue for roasting the lime, and then the exhaust gas from the lime kiln was used for coke drying before being drawn forth to the power plant to utilize its latent heat.Most of the pollutants were burned and wiped out, and then the waste gas was conducted into the smoke control system to remove the rest pollutants.Near zero emission could be realized by using this technology for calcium carbide industry.
