近几年来,随着国民经济的快速发展,我国电石行业步入了一个黄金发展时期。2000～2007年,电石产能年均递增22.6%,产量年均递增23.4%。但是,在快速发展的同时,电石行业也存在着能耗高、污染严重、产能过剩等问题,也因此成为国家节能减排工作的重点调控对象。由于国家出台了更为严格的准入条件并加大淘汰落后产能的力度,未来几年内我国电石行业产能扩张速度将放缓,而随着下游PVC等行业对于电石需求量的不断增加,预计到“十一五”末期,我国电石产能过剩的矛盾将得到一定的缓解。另外,由于国家对电石行业节能减排工作提出了更高的要求,因此今后几年电石行业的工作重点是将内燃式电石炉改造为密闭式电石炉,从而降低行业能耗、减少污染物排放。
In recent years, with the rapid development of the national economy, China’s calcium carbide industry has entered a golden period of development. From 2000 to 2007, calcium carbide production capacity increased by 22.6% annually with an average annual output of 23.4% increase. However, with the rapid development, the calcium carbide industry also has some problems such as high energy consumption, serious pollution and overcapacity. Therefore, it has become the focus of regulation and control of the national energy conservation and emission reduction work. As the state has introduced more stringent access conditions and increased elimination of backward production capacity, the next few years, China’s calcium carbide industry capacity expansion will slow down, and with the downstream PVC and other industries for the growing demand for calcium carbide is expected to “Eleventh Five-Year ” end, the contradiction between China’s calcium carbide overcapacity will be some ease. In addition, as the state puts forward higher requirements on the energy conservation and emission reduction in the calcium carbide industry, the emphasis of the calcium carbide industry in the next few years is to transform the internal combustion type carbide furnace into a closed calcium carbide furnace, thereby reducing the energy consumption of the industry and reducing the emission of pollutants .
