陶瓷滤管一体化工艺在不同烟气工况下的循环路线分析

随着玻璃窑炉烟气治理工艺的发展,传统烟气治理工艺处理步骤多、设备数量多、占地面积大、投资大,后期运行的成本高。陶瓷滤管一体化脱硫脱硝除尘工艺实现脱硫、脱硝、除尘协同治理,处理步骤减少,运行维护简单,逐渐成为玻璃行业污染物治理的主要技术路线之一。基于陶瓷滤管一体化的工艺路线,根据不同的烟气工况、不同初始硫化物浓度,兼顾脱硫效率、物料考核和运行成本选择合适的熟石灰循环工艺至关重要。

A Survey of Social Nutrition Status of the Elderly in theUrban Area of Chengdu, Sichuan Province

The social nutrition status was investigated among 246 subjects aged 60-90 living at three urban communities in Chengdu of Sichuan Province. The questionnaire was designed to evaluate socirydeweraphic background, the subjects' nutrition knowledge, and the support systerns for geriatric nutrition. Fasting venous blcod was colected for the analysis of biochemical parameters. Blood pressure, bene mineral contents (BMC), body weight (BW) and they height (BH) were measured at the same time. Only 49. 7% of the subjects correctly an swered four basic questions on nutrition. Food patterns for the elder1y were simple and modest. Several nutrition-related disorders for the elderly were including high systolic bbo pressure (44. 6 % ), hyPertriglyceridemia (25. 9 % ), high diasto1ic blood pressure (25. 1% ),obesity (24. 5% ), high PBG (20. 6% ), emaciation (19. 9%), high FBG (17.9%) and osteoporosis (16. 8%). These data indicate that the support systems for the geriatric nutrition will have to be improved.

触媒陶瓷滤管一体化干法烟气脱除技术在玻纤行业中的应用
