The Technology And Economic Analysis Of Shenyang Primary Sewage Heat Energy

With the development of national economy and the people of living standard unceasing enhancement,building energy consumption accounts for the proportion of the total social energy consumption is biger and biger, the more energy consumption increased urban environment pollution. Environmental pollution and energy crisis has become a threat to human living, how to develop new energy resources and the sustainable development of social development has become the primary problem. Primary sewage heat energy utilization technology demand arises at the historic moment in the background, primary sewage as a heat in winter and summer, is a kind of high efficiency and energy saving of the sustainable development of new heating way. But the primary sewage heat energy utilization has not been widely recognized by the government, developers and users, especially in shenyang city, primary sewage heat energy utilization of development is still in researching stage, economy, energy efficiency and other comparative study with other heating systems is lagging behind, limiting the native sewage heat energy utilization smooth progress in Shenyang city.Therefore, a comprehensive analysis the native sewage comprehensive evaluationtent and develop the basis of policy is the promotion of the key issues to promote sewage heat energy utilization in Shenyang.The paper is taking shenyang primary sewage heat energy utilization feasibility as the research object, comprehensive of raw sewage and sewage source heat pump theory, researching domestic and international raw sewage heat utilization, analysis of the current situation of the heating in Shenyang, based on analysis of the advantages and promote the presence of raw sewage in the process of development in Shenyang, market issues affecting development in Shenyang is the main problem of raw sewage.According to the existing problems in the raw sewage promotion and Shenyang city heating status quo, building principles and inspection of the combination of system evaluation literature, build native sewage heat energy utilization evaluation, the evaluation includes four aspects, they are conomic indicators, energy efficiency indicators, environmental indicators, and the applicability of indicators, to use literature Screening native sewage heat energy utilization of three evaluation and analysis of four indicators; according to the construction of the evaluation indicators, using thermal economics model analysis primary sewage heat energy utilization system and coal fired boiler system, gas boiler system and fuel boiler system unit heating costs, calculating the primary sewage relative to other three kinds of heating energy saving and reduction of pollutant emissions, combining with the applicability of the four schemes, the fuzzy evaluation model of heating unit each index comprehensive evaluation calculation, evaluation four schemes can number sequence. In this paper, we select the people’s procuratorate of liaoning province as an example, scheme in shenyang HuangGuOu, heating mode by primary sewage heat energy utilization system. using the research method, we calculate the primary sewage heat energy utilization system and the other three kinds of heating mode unit heating cost, energy saving and pollutant reduction, and using the fuzzy comprehensive evaluation proved primary sewage heat energy utilization system is four kinds of solutions of the optimum scheme. Accordingly, proof that the primary sewage heat energy utilization system, and puts forward the superiority of shenyang primary sewage heat energy utilization development of countermeasures.This paper innovation points include:analysising native status of sewage and use of the application conditions in Shenyang city, cmprehensive analysis and other heating mode contrast, thermal economics model and the fuzzy comprehensive evaluation model used in primary sewage economic and comprehensive evaluation analysis, and the introduction of the superiority of the Shenyang City the successful examples prove Shenyang city native sewage compared to other heating methods, fill the shenyang primary sewage utilization theory research blank, for formulating government primary sewage development decision-making to provide constructive comments and uggestions.
