Experimental Study on Characteristics of MSW Pyrolysis Gas

Integrated Installation for Dust Recovery and Rhenium Absorption from Molybdenite Concentrates Mine Roasting Flue Gases

7th World Congress on Recovery, Recycling and Re-integration

作者： Hanqiao Liu, jiuju cai SEPA Key Laboratory on Eco-industry, Northeastern University, P.O Box 345, Shenyang, Liaoning, China Xiangjun Bao Shougang Technical Research Institute, Beijing, China

Based on metallurgical coking technology, a new interlayer pyrolysis system of municipal solid waste (MSW) is put forward by combining out-heating pyrolysis technology with regenerate combustion technology. The system has such advantages as quit innocuity, little secondary pollution and high recycling efficiency. There is certain requirement for the quantity and quality of the pyrolysis gas to supply the energy for maintaining the reaction temperature of the pyrolysis system. To provide reasonable operating conditions of the system, experiments were carried out in a homemade indirect resistance furnace (20 kW). 1 kg sample consisting of vegetable, plastics, paper and woods as typical components of MSW was used The effects of process conditions including temperature, heating rate, moisture and amount of blending coal on pyrolysis gas characteristics such as yield, composition and calorific value were studied. Some conclusions can be drawn from the experimental results: (1) In pyrolysis of MSW, the gas yield increases with final pyrolysis temperature increasing. High heating rate favors cracking of the hydrocarbons in gaseous products, and thus increases the content of H2, (2) There is a prominent influence of the moisture of MSW on pyrolysis gas. The lower the moisture, the higher the yield and the calorific value of recycled gas, (3) The pyrolysis time is shortened when the amount of blending coal is increased because it increases the bed porosity, improving the heat transfer. The blending coal can also improve the stability of gas products

7th World Congress on Recovery, Recycling and Re-integration

作者： Hui Dong, jiuju cai, Tao Du, Aihua Wang, Hanqiao Liu, Lianyong Wang, Jun Yang SEPA Key Laboratory on Eco-lndustry, Northeastern University, P.O Box 345, Northeastern University, Shenyang, Liaoning, China

Molybdenite concentrates mine with rhenium is the main raw material of ferromolybdenum and molybdenum chemical engineering production. In the roasting process, the flue gases including Re2O7, MoS2, MoO3, MoO2, SO3 and SO2 are produced. It is of great significance to recover the dust and absorb rhenium from the flue gases. However, there are few feasible and economical installations to recover dust and absorb rhenium from the flue gases. In allusion to the situation, we bring forward a new type of integrated installation to recover dust and absorb rhenium from the roasting flue dust of molybdenite concentrates mine with rhenium. Three kinds of advanced technologies were combined organically as follows The self-swash dust catcher with the unique overfall device was adopted to recover the dust and absorb rhenium from flue gases to be purified firstly, and then the spherical tray power was utilized to recover the dust and absorb rhenium again, and then the vapor (gas)-water segregator was used to recover the dust and absorb rhenium finally. It is first time that the type of equipment was domestically applied to the production of dust recovery and rhenium absorption from flue dust of roasted molybdenite concentrates mine with rhenium successfully. It has been proved in practice that the equipment is feasible, has great elution efficiency and has the advantages of simple structure, convenient operation, low cost and low energy consumption. In addition, the equipment can also be applied to wet dust recovery in such fields as metallurgy, mining, chemical industry, building materials industry and so on.

为评价医疗垃圾焚烧灰渣对环境的危害性及寻找安全有效的处理方法,利用X-射线荧光光谱仪、X射线衍射仪、扫描电镜、原子吸收光谱仪等仪器分别对回转窑式、固定床式医疗垃圾焚烧炉的布袋飞灰及底渣进行化学成分、物相、微观形貌、重金属... 详细信息

为评价医疗垃圾焚烧灰渣对环境的危害性及寻找安全有效的处理方法,利用X-射线荧光光谱仪、X射线衍射仪、扫描电镜、原子吸收光谱仪等仪器分别对回转窑式、固定床式医疗垃圾焚烧炉的布袋飞灰及底渣进行化学成分、物相、微观形貌、重金属含量及渗沥行为等特性分析.结果发现,回转窑式和固定床式布袋飞灰热灼减率分别为31.2%、34.6%,两者Cl、SO3和碱金属含量均较高,主要物相为CaSO4和NaCl,且Cd、Zn、Pb等重金属渗沥浓度均超过危险废物填埋允许限值,其渗沥行为可能与布袋飞灰的不规则多孔海绵状微观形貌有一定关系;2种底渣主要由复杂硅酸盐构成,其渗沥浓度低于危险废物规定的阈值.因此,2种布袋飞灰经预处理后方能进入危废填埋场填埋,2种底渣可按一般工业固废直接填埋.

应用竖炉散料气固换热模型,分析了在固定换热设备结构时,吨矿风量、空气入口温度、烧结矿入口温度对空气出口温度、烧结矿出口温度、余热回收火用的影响。通过对比实际生产数据与计算数据验证了换热模型合理性,最后利用正交实验优化操作参数改善回收火用量。研究结果表明:随着吨矿风量增大,空气和烧结矿出口温度降低;随着空气和烧结矿入口温度升高,空气和烧结矿出口温度升高;余热回收火用随吨矿风量和空气入口温度增大而降低,随烧结矿入口温度升高而增大;当空气入口温度20℃,吨矿风量900m^3/t,烧结矿入口温度750℃时,余热回收效果最优。
