太阳能与生物质锅炉联合加热增温系统的试验研究

Experimental Study on United Heating System of Solar Energy and Biomass Boiler

我国北方高寒地区气温较低,特别在冬季,温度是影响厌氧发酵微生物的活性、制约沼气发酵的重要因素,也是限制在高寒地区发展建设大型沼气工程的关键问题。为解决这一问题,提出了利用太阳能与生物质锅炉联合为厌氧发酵系统加热增温的新思路,并以依安县依龙镇丰林村大型沼气工程为研究对象,利用力控组态软件随时监测和采集反应器正常运行情况下加热系统的数据。同时,对当地最冷月份1月的运行数据进行了分析,结果表明:在正常工作条件下,该系统可以保证大型沼气反应器冬季的正常产气,对北方高寒地区发展大型沼气工程具有重要的指导意义。

The temperature is low in northern frigid area of our country, especially in winter. The temperature is the key factor that seriously affecting the activity of anaerobic fermentation microorganisms and restricting the biogas fermentation, and it is also the key issue that restricting the development and construction of the large-scale biogas project in frigid area. In order to solve this problem, a new idea is proposed in the paper, which heating for anaerobic fermentation system by the utilization of solar energy and biomass boiler, and takes the large-scale biogas project as the object of research in Fenglin village, Yi Long town, Yi＇ an County. The data of heating system under normal operation conditions of reactor can be monitored and acquired at any time by using the Force Control Configuration Software. Through the analysis of operation data of local coldest month （January） , the results show that the system under normal conditions can ensure the conventional gas production of large-scale biogas reactor in winter, which has an important guiding significance to the development of large-scale biogas project in northern frigid area.
