目前,我国已是世界上最大的木业加工、木制品生产基地和最主要的木制品加工出口国,我国的人造板、家具、地板年产量已经位居世界前列。江苏宿迁地区共有此类木材加工规模企业700余家,年产生约22万t的砂光粉,因无合理的方法将其使用,导致了资源浪费和环境污染。本地区现有工业锅炉2000余台,其中能效水平低下、污染物排放严重、自动化水平低的燃煤工业锅炉约占90%,节能潜力巨大。砂光粉在本
At present, our country is already the largest wood processing and woodworking production base and the most important exporter of wood products in the world. China’s annual output of wood-based panels, furniture and flooring has topped the world rank. A total of more than 700 such wood processing enterprises are located in Suqian, Jiangsu Province, with an annual output of about 220,000 tons of sanding powder. As a result, there is no reasonable way to use it, resulting in waste of resources and environmental pollution. There are more than 2,000 industrial boilers in the region, of which, the energy efficiency level is low, the discharge of pollutants is serious, and the low-automation coal-fired industrial boilers account for about 90%, which has great potential for energy saving. Sanding powder in this
