Reuse world

Leshan major projects completed ahead of annual investment, and successfully used to create polysilicon industry chain of waste and other industrial environmental projects.

to Leshan Giant Buddha, the world-famous scenic spots such as Mount Emei, Leshan City, in recent years, industry has achieved rapid development, the city’s 61 major projects at present a total investment of 120.9 billion yuan in 2008, plans to invest 6.822 billion yuan. The first three quarters completed an investment of 7.015 billion yuan to complete the investment plan of 103%, ahead of the completion of annual investment over a quarter of the task. Can Leshan industrial development while protecting the mountains and blue sky, has become the public are most concerned about. Le reporter visited the Shandong Automobile E Mountain and a half polysilicon, E Mountain wins cement and other items, to find the answer.

item a poly-silicon and the waste industry chain turning waste into the highest selling 40,000 yuan per ton yesterday

, located in Leshan Wutongqiao E Mountain east half of 1500 tons polysilicon gas project point to the 55 days countdown. “World War 100 days, captured 1500″ signs erected at the site entrance. Two months later, the project will put into operation, together with previously 3,000 tons of polysilicon production projects, Leshan polysilicon production capacity will reach 4,500 tons, and firmly laid the Leshan domestic polysilicon production capacity first position.

“We spent 160 million yuan from the United States purchased the waste recovery system to ensure the production of raw materials into the factory, the factory is the product, not polluting the environment.” Dongfeng E Mountain polysilicon project-related half-white person in charge is said, produce more crystalline silicon by-product processing is a world-class problems, for every 1 ton polysilicon production, will produce about 15 tons of silicon tetrachloride (silicon tetrachloride case of heat or moisture liberation of heat, emit toxic corrosive flue gas) . To this end they spend huge sums of money to buy the patent for waste recycling, reduction.

Leshan Development and Reform Commission, according to Luo Li introduced Leshan in the polysilicon project launched the same time, focus on technology research efforts, successfully capturing the exhaust recycling technology and equipment, large-scale thermal silicon tetrachloride hydrogenation technology and devices, a number of key technologies . Silicon industry and other enterprises at the Sunbeam,

silicon tetrachloride by-product recycling, the can no longer be producing polysilicon raw materials. Not only that, Leshan is also under the concept of circular economy, successfully building a polysilicon recycling of industrial chain. At the five-pass bridge, Leshan Fuhua Group, dealing with the main waste polysilicon silicon tetrachloride project - white carbon black (used as rubber reinforcing agent, coating, thickening agent, etc.) project was started in May this year, the final The production scale will be up to 4 million tons. Through the technical processing of silicon tetrachloride into silica, the per ton price of up to thirty or forty thousand yuan. At the same time, organic silicon, optical fiber preforms such as silicon tetrachloride as the raw materials to the project have also been launched, these projects put into operation, Leshan radius within the past 10 years dozens of polysilicon production of waste will be all “eat”, turning waste into treasure, resulting in substantial benefits.

Item 2 of the cement production line environment cogeneration annual cost savings of 40 million yuan

to E Mountain wins cement plant, clear streams and green trees people feel that it is a cement surrounding environment. “Each production line, for the environmental protection investment accounts for 20% of the cost.” E Mountain Sheng Xiong, chairman said, a 200-million tons of cement production lines, construction cost is 650 million light heat power generation equipment investment as high as more than 9000 10000. Xiong said the cement plant is a high energy-consuming enterprises, waste heat power generation system after the use of the kiln exhaust gas waste heat power generation systems, each system, generating 80 million kwh per year, to resolve 38% of the production of electricity demand, saving electricity costs more than 4000 million.

E Mountain wins a two million tons of cement a new dry process cement production line went into operation last year. On the 2nd line will be put into operation next month, San Haoxian put into operation in March next year. By then, the E Mountain wins an annual output of cement will reach 6.6 million tons, is expected to become the largest cement production base in Sichuan Province. With the traditional mechanical shaft kiln process line compared to new dry process cement production lines can be directly saved each year 93.5 million tons of coal, power-saving 6650 kwh.

乐山循环经济概念结晶硅废料卖了很多钱

乐山市重大项目提前完成年度投资，并成功地用于制造多晶硅的工业废物和其他环保项目的产业链。

的乐山大佛，大佛是世界著名的风景区，如峨眉山，乐山市景点，近年来，行业取得了快速发展，全市61个主要目前的1209.00亿，2008年累计投资项目，计划投资68.22亿元。前三个季度完成了70.15亿元的投资，完成投资计划103％，提前超过一季度的年度投资任务的完成。可乐山工业发展，同时保护山区和蓝天，已成为市民最关心的问题。乐记者走访了山东汽车峨半多晶硅，峨胜水泥和其他物品，寻找答案。

项目1多晶硅及废物产业链变成废物销量最高的每吨40,000元昨日

，位于乐山市五通桥峨1500吨多晶硅项目点，东部天然气上半年向55天倒计时。 “世界大战100天，抓获1500”在现场入口处竖立。两个月后，该项目将投产，加上先前3000多晶硅生产项目，乐山多晶硅生产能力将达到4500吨，牢牢奠定了乐山国内多晶硅产能第一的位置吨。

“我们花了从美国购买了1.6亿元的废物回收系统，以确保原料进厂生产，工厂的产品，不污染环境。”东风峨多晶硅项目相关的半白负责人说，生产更多的晶体硅副产物处理是一个世界级难题，每生产1吨多晶硅，将生产约15吨的四氯化硅（四氯化硅案热或水分解放热，放出有毒的腐蚀性烟气）。为此，他们花巨资购买，废物回收利用，减少专利。

乐山市发展和改革委员会，根据罗理介绍了乐山多晶硅项目启动同时，对技术研究工作的重点，成功地捕捉排气回收技术和设备，大型四氯化硅热氢化技术和设备，一个数字关键技术。硅业和新光等企业，

四氯化硅的副产品回收利用，再也不能生产多晶硅的原材料。不仅如此，乐山也属于循环经济的概念，成功地建立了产业链的多晶硅回收。在五通桥，乐山市富华集团，其主要废料四氯化硅多晶硅项目-白炭黑处理（如橡胶用补强剂，涂料，增稠剂等），项目于今年5月开始，最终的生产规模将达到400万吨。通过四氯化硅的技术加工成硅石，每吨的价格高达30或4.0万元。同时，有机硅，光纤预制棒，如硅作为项目的原料四氯化碳也已推出，这些项目投产，将乐山半径在过去10年的多晶硅生产废物打，所有“吃“，把废物为宝，产生可观的利益。

项目2环境的水泥生产线余热发电4000万元每年可节约成本

向峨胜水泥厂，清澈的溪流和绿树的人觉得这是一个水泥的周边环境。 “每个生产线，为保护环境为20％的成本投资账户。”峨盛雄，主席说，200万吨水泥生产线，造价为650万光年的热量发电，有超过9000万的高设备的投资。熊光楷说，水泥厂是高耗能企业，后窑废气余热发电系统，每个系统使用余热发电系统，发电8000万千瓦时每年，解决38％的生产电力需求，节省电费开支超过4000万。

峨胜水泥新新型干法水泥生产线投产，去年超过两百万吨。二号线将于下月开始运作，新贤把三月明年正式投入服务。届时，峨胜一水泥年产量将达到6.6万吨，有望成为最大的水泥生产基地四川省。与传统的机械立窑生产线相比，新型干法水泥生产线，可直接节省每年九千三百五十点〇 〇万吨煤炭，电力节能六六五○千瓦时。08.10.20
