本文在分析近代太阳热发电和海水温差热发电的优缺点后,用实测资料和理论两方面说明我国山东半岛南北的黄海海域常年存在低温的深层冷水团,夏季冷水团的温度约6～8℃,而且核心区历年稳定。在黄海冷水团的海面及其近海、近陆又是太阳能照射条件好的地区。因此建议用技术经济上较易实现的集热温度为100～300℃(本文称之为低中温low-moderato temperature)的太阳能集热器所收集的太阳热作热源,再以这些水域的深层冷水团作为冷源,采用恰当的低沸点流体(本文采用R-114)为工质,组成热力循环,联合用太阳热和深水温差热发电,就有可能克服原有的纯太阳热或纯温差热发电的缺点和困难。文中论述了这种联合电厂的优缺点,并以热力计算结果给以论证,了解它在技术、经济上的可行性和优越性。如此将地区能源作综合利用,使不同能源能扬长避短,联合发电和供热,则各能源可获得最有利的利用。
After analyzing the advantages and disadvantages of modern solar thermal power generation and seawater thermoelectricity thermal power generation, this paper illustrates the perennial low temperature deep cold water mass in the Yellow Sea in south and north of Shandong Peninsula by using measured data and theory. The temperature of summer cold water mass is about 6 ~ 8 ℃ , And the core area has been stable over the years. In the Yellow Sea cold water and its offshore sea, inland and solar radiation is good conditions. Therefore, it is suggested to use the solar heat collected by the solar collector which is technically and economically easy to be collected at a temperature of 100-300 DEG C (herein referred to as a low-mode temperature), and then the deep cold water in these waters It is possible to overcome the existing pure solar heat or pure temperature difference heat by using the low-boiling point fluid (R-114 in this paper) as the working fluid to form the thermodynamic cycle. When combined with solar heat and deep-water thermoelectric power generation, Disadvantages and difficulties of power generation. In this paper, the advantages and disadvantages of such a combined power plant are discussed, and the results of the thermal calculation are given to demonstrate its technical and economic feasibility and superiority. In this way, the comprehensive utilization of energy resources in the region will enable different energy sources to play their respective strengths and weaknesses, co-generate electricity and provide heat, and then the most beneficial use of all energy sources will be achieved.
