东北玉米烘干机实施节能减排技术措施   总被引:1,自引:0,他引:1  
我国东北地区玉米烘干机系统热效率低、能耗高、污染重,对其采取废气回收、烟气余热利用、设备保温处理、改变气流走向、更换分层煤斗和高效换热器等技术措施,收到了明显的节能减排效果。换热器进风口平均风温提高了30℃以上;排烟温度降低了30℃以上;节煤15%以上;废气中的皮屑和粉尘回收率可达80%。既节约了资源,又保护了环境。  相似文献

1.选择高效节能电动机 购买电动机时,应首先考虑选用高效、节能、高功率因数的品牌,然后按需要考虑其他性能指标,以利节约电能,如从经济角度考虑,应尽量选用Y系列(或YX等)节能型电动机。另外,有三相电源的地方,一定要选择三相电动机,这是因为三相电动机比相同功率的单相电动机体积小、重量轻、振动小、效率高。  相似文献

正我国经济飞速发展,取得巨大成就的同时,也付出了巨大的资源和环境代价,这种状况与经济结构不合理、增长方式粗放直接相关。再加上我国人均自然资源、能源占有率较低,不加快调整经济结构、转变增长方式,资源支撑不住,环境容纳不下,社会承受不起,经济发展将难以为继。只有坚持节约发展、清洁发展、安全发展,才能实现经济又好又快发展。在全国大力推进节能减排的背景下,粮油仓储行业不能置身事外,同样大有作为。  相似文献

A coking plant extended many times, and its capacity of the cooling water system is not match with it, the consumption of new water is much more than that used by others in the same industry. The water system renovation is addressed for an extended coking plant. The installation of two 600 m3/h cooling towers and restoration the existing two cooling towers are to promote the cooling capacity so that the amount of discharge and feed could be reduced. At the same time, the pipe net for waste water reutilisation is installed, by which part of the waste water is reused as supplement water for quenching hot coke and the other was piped to ironworks for reuse. With the field test, the water consumption per ton of coke production is cut down from 9.03 m3 to 3.21 m3. And the annual water saving is more than 6×106 m3. Furthermore, the electric consumption is reduced by 2×106 kWh and about 3×106 yuan of annual running cost is saved.  相似文献

卫生填埋是生活垃圾最主要的处理方式,生活垃圾卫生填埋场产生甲烷(CH4)等温室气体,加快全球气候变暖进程,引起各国政府的高度重视。笔者探讨了影响生活垃圾卫生填埋场CH4产生的因素,对CH4减排技术进行了总结。目前,生活垃圾卫生填埋场CH4减排技术主要包括填埋层原位减排、资源化利用和末端控制技术等。为了控制和减少CH4排放量,中国需要增加技术和设施投入,加强生活垃圾卫生填埋场气体排放的管理,开发有效的CH4抑制技术,建立适合中国国情的CH4等温室气体减排技术体系。  相似文献

利用改进后的全球一般均衡环境模型(GTAP-E)及其6版非CO2类温室气体排放数据库,模拟了中国非CO2类温室气体减排潜力及其政策意涵。结果显示,现阶段,中国是世界上非CO2类温室气体排放最多的国家,2020年将会占到世界总排放的20%左右。其中,来自农业部门的非CO2类温室气体排放比重达到73%。未来10年,牛羊类、工业、服务行业的非CO2排放增速最快,且服务业的增速快于工业,并在2010年后超过工业排放。中国可以通过实施非CO2类温室气体减排政策,减轻二氧化碳减排的国际压力。虽然征收较高的碳税能够带来较高的非二氧化碳减排量,但是政策效率在高碳税和低碳税间差异不大。所以,在实施非二氧化碳减排碳税政策时,应该把碳税控制在一个较低的水平。  相似文献

Iron and zinc grain density in common wheat grown in Central Asia   总被引:5,自引:0,他引:5  
Sixty-six spring and winter common wheat genotypes from Central Asian breeding programs were evaluated for grain concentrations of iron (Fe) and zinc (Zn). Iron showed large variation among genotypes, ranging from 25 mg kg−1 to 56 mg kg−1 (mean 38 mg kg−1). Similarly, Zn concentration varied among genotypes, ranging between 20 mg kg−1 and 39 mg kg−1 (mean 28 mg kg−1). Spring wheat cultivars possessed higher Fe-grain concentrations than winter wheats. By contrast, winter wheats showed higher Zn-grain concentrations than spring genotypes. Within spring wheat, a strongly significant positive correlation was found between Fe and Zn. Grain protein content was also significantly (P < 0.001) correlated with grain Zn and Fe content. There were strong significantly negative correlations between Fe and plant height, and Fe and glutenin content. Similar correlation coefficients were found for Zn. In winter wheat, significant positive correlations were found between Fe and Zn, and between Zn and sulfur (S). Manganese (Mn) and phosphorus (P) were negatively correlated with both Fe and Zn. The additive main effects and multiplicative interactions (AMMI) analysis of genotype × environment interactions for grain Fe and Zn concentrations showed that genotype effects largely controlled Fe concentration, whereas Zn concentration was almost totally dependent on location effects. Spring wheat genotypes Lutescens 574, and Eritrospermum 78; and winter wheat genotypes Navruz, NA160/HEINEVII/BUC/3/F59.71//GHK, Tacika, DUCULA//VEE/MYNA, and JUP/4/CLLF/3/II14.53/ODIN//CI13431/WA00477, are promising materials for increasing Fe and Zn concentrations in the grain, as well as enhancing the concentration of promoters of Zn bioavailability, such as S-containing amino acids.  相似文献

Aimins at the state that present central air- conditioning systems performance in high ineffective energy consumption, this paper studies the reasons of ineffective energy consumption and the key technique to solove the problem. A set of energe saving device for central air - conditioning systems is developed. A system dynamical mathematical model is established in theory, and an optimal performance pattern is fired. The central air - conditioning system can work in the optimal pattern with effective comfortability and saving energy by using. The device may save power rate to 22.6% by survey and may have broad market prospect in the southern area.  相似文献

为研究抗战胜利70周年活动期间气象条件对空气污染的影响和应急减排效果,以河北南部邯郸为例,利用2015年8月1日—9月3日邯郸环境监测站数据、邯郸气象站气象资料进行分析。结果表明,应急减排期间(8月23日—9月3日)邯郸市大气污染物浓度明显下降,8月23日—9月3日全市PM2.5平均浓度比减排前(8月1—22日)下降46.3%,9月1—3日全市连续3天空气质量达优。从逆温强度、混合层高度、通风系数、风速、小风日数、降水等气象条件及后向轨迹分析表明,减排期间大部分时段受静稳天气影响,不利于空气污染物垂直扩散;气团后向轨迹分析表明:以本地气团为主;应急减排使相同气象条件下污染物浓度明显下降,有力的减排措施是空气质量改善的根本原因。  相似文献
