【摘要】 燃煤电厂排放的大量粉煤灰已对生态环境形成了严重的污染，并造成了资源的极大浪费。近年来，随着我国社会经济的发展，人们的环保意识普遍增强，粉煤灰资源化利用已成为我国实施可持续发展战略，解决能源、环境与经济发展之间矛盾的一项重要内容。 本文提出了粉煤灰静电脱炭原理和技术，即采取技术措施使粉煤灰中炭粒和无机灰粒在进入静电场前分别带上异性电荷，利用电场力的作用把炭脱去。据此，本文设计制造出一套处理量0.18t／h的粉煤灰脱炭试验装置。这套试验装置主要包括给料装置、摩擦分散器、高压静电分离器、颗粒收集器、风管、风机等部分。 初步试验结果表明，原状粉煤灰经本试验装置脱炭处理后，脱炭率达到29％，具有一定的脱炭效果。同时本文根据试验运行情况，对该试验装置进行的效益分析表明，采用本装置可以产生较好的经济效益、社会效益和环境效益。更多还原

【Abstract】 Mass fly ash which is produced by coal combustion power plant has badly polluted entironment and wasted resource. With the development of society and economy, people have become thinking highly of environment protection. The resourceful utilization of fly ash has become the important part of continuous development strategic practice and solving the contradiction among energy, environment and economy development.In this paper, the principle of .fly ash static doffing charcoal has been brought forward. That is: using some measure and making charcoal grain and abio-ash grain of fly ash carry isomerism charge before they enter into static electric field. Then, the charcoal are separated at the action of high voltage static electric force. Hereby, this paper designed a fly ash doffing charcoal experimental installation which can disposed 0.18kg fly ash among one hour. This installation is composed of material feeder, implement of friction and decentralization, high voltage static separator, implement of grain collecting, wind pipe, windmachine.The beginning experiment shows: after disposed by this installation, the doffmg-charcoal rate of original fly ash can achieve 29%. At the same time, based on the circulating test, the possible benefit about this set are estimated. The result shows: this installation can produce much economy benefit, society benefit, and environment benefit.Establish and operation of this installation is an available experiment of new approach about fly ash resourceful utilization. It may be hopefully to make use of this installation to empolder a brief and effective fly ash resourceful utilization new technology.更多还原
