Industry Enterprises Energy Saving And Ejection Decreasing Research

The three towns of Xiangzhi,hongshan,Jinshang in Shishi city have 84 industrial enterprises,mainly specialized in the develop the heavy pollution industries such as dyeing and finishing,bleaching and dyeing and electroplating. The existing small boilers are not concentrated,result the pollution of the environment atmosphere.The Implement of Hongshan thermoelectricity Engineering of Fujian is in order to meet the increasing heat need of the enterprises of in Xiangzhi,Hongshan and Jinshang Industry areas,alleviate the air pollution,improve the ecosystem environment of the native area.This paper overviewed the domestic and abroad energy saving and ejection decreasing Indicators system,combined with the status of the three industry areas, established a energy saving and ejection decreasing Indicators system of three towns' industries areas in Shishi,compared the Indicators system of fore and after the establishment of the Hongshan thermoelectricity Plant,thus put forward central heating energy saving and ejection decreasing suggestions of the enterprises.First,the paper reviewed the research development of energy saving and ejection decreasing domestic and abroad;thus the indicators system of energy saving and ejection decreasing was designed applying the principles of scientific, systemic,comparable,feasibility,qualitative and quantitative combined together. The structure of the indicators system contained three layers,the top of which is the target of the system,the second layer consised of two attribution indicators up to the subsystem,the bottom was made up of ten material variables.By the comparison of index before the execution of the contral heating energy save and ejection decreasing measures in three towns industries areas of Shishi, we can found that the establish of Shishi Hongshan thermoelectricity Plant can save the coal consumption about 115.2 thousand t/a from the regional,as well as increasing the territorial electricity consumption by 4426.2 thousand Kwh,but it also can create electricity power about 8.928*10⁷KW.h/a to alleviate the tense electricity supply situation in the city of Quanzhou.Theoretically it can save water consumption 13t/h,but except heat supply by Shishi Hongshan thermoelectricity Plant,it also can generate electric power,if just consider the point of heat supply,the economized water consumption is not just these.And it can save composite energy consumption 8.1×10³toe.It can replace the regional scattered boiler step by step,and reduce regional SO₂ emission about 6267.65t/a,TSP about 3523.08t/a,NO×8137t/a directly.At the same time,it can directly reduce regional furnace dust emission and wasted water emission by 3.8×10⁴t/a and 10.21t/h respectively.On the base of the index calculation,we analysed the central heating energy saving and ejection decreasing fore and after the execution of the Shishi Hongshan thermoelectricity Plant,thus put forward countermeasures.
