It is currently an advanced recovery system with the advantages of stable and reliable performances, low operating cost, high economic profit, short process flow and no need of cooling water. 设备性能稳定,运行可靠,不需要冷却水,工艺流程短,运行费用低,经济效果显著,是目前国内同行业中光进的回收设备。
But because of the gap of social and economic between our country and the developed countries, the domestic research on coal gangue waste land behind the advanced level, the recovery mode and technology of the abandoned coal gangue are not mature, lack of the scientific system. 但由于我国与发达国家的社会、经济差距及研究时间较短等原因,国内对煤矸石废弃地的研究整体落后于发达国家,煤矸石废弃地恢复的模式和技术都不成熟。
The energy consumption analysis of individual equipment and heat exchanger networks, application of high-efficiency heat exchangers and advanced surplus heat recovery technology and optimization of heat exchanger networks are effective and dependable ways for energy-saving of chemical process system. 对化工过程系统的换热网络和单体设备进行用能诊断、应用高效换热设备和先进的余热回收节能技术、优化换热网络是化工过程系统节能行之有效的途径。
