【摘要】：隨著世界人口的增加、工業(yè)化的加快,能源消耗量逐年增加,能源的緊缺形式也逐年加劇,節(jié)能技術(shù)已成為當(dāng)今科技發(fā)展的主流,節(jié)能降耗也逐漸成為各工業(yè)公司和工廠開展工作的主要目標(biāo)。本論文將以節(jié)能降耗為基本出發(fā)點(diǎn),分析目前各電廠中凝結(jié)水泵存在的各類問題,總結(jié)凝結(jié)水泵進(jìn)行節(jié)能優(yōu)化改造的各種途徑和不同措施。針對(duì)內(nèi)蒙古岱海發(fā)電有限責(zé)任公司二期#3、#4機(jī)組(600MW亞臨界空冷機(jī)組)凝結(jié)水泵的設(shè)計(jì)壓頭偏高,節(jié)流損失較大,導(dǎo)致系統(tǒng)效率偏低的現(xiàn)象,在性能測(cè)試的基礎(chǔ)上,從機(jī)組安全與節(jié)能兩方面考慮,分析了凝結(jié)水泵存在配套性差、裕量大、泵運(yùn)行效率較低的問題,進(jìn)行了凝結(jié)水泵通流部分的節(jié)能優(yōu)化改進(jìn)、變頻改造以及運(yùn)行方式的優(yōu)化改造。改造后提高了泵與電機(jī)的配套性和效率,最高運(yùn)行效率從改前的74.83%提高到80.12%,揚(yáng)程下降了87—57m,電機(jī)電流下降明顯,完全達(dá)到了預(yù)期的效果,經(jīng)濟(jì)效益非常顯著。
[Abstract]:With the increase of the world population and the acceleration of industrialization, the energy consumption is increasing year by year, and the energy shortage is becoming more and more serious year by year. Energy saving technology has become the mainstream of the development of science and technology. Energy saving and consumption reduction have gradually become the main targets of industrial companies and factories. This paper will take energy saving and consumption reduction as the basic starting point, analyze all kinds of problems existing in condensate pumps in power plants at present, sum up various ways and different measures for optimizing energy saving of condensate pumps. In view of the phenomenon that the design of condensate water pump of #3Pu #4 unit (600 MW subcritical air cooling unit) of Daihai Power Generation Co., Ltd, Inner Mongolia, is on the high side and the throttling loss is large, which leads to the low efficiency of the system, based on the performance test, Considering the safety and energy saving of the condensate pump, the problems of poor matching capacity, large margin and low efficiency of the condensate pump are analyzed, and the energy saving optimization improvement of the flow passage part of the condensate pump is carried out. Transformation of frequency conversion and optimization of operation mode. After revamping, the matching performance and efficiency of pump and motor are improved, the maximum operating efficiency is increased from 74.83% to 80.12%, the head is reduced by 87-57 m, the motor current is obviously decreased, the expected effect is completely achieved, and the economic benefit is very remarkable.
