【摘要】：近年來，我國大力開發(fā)水電資源，水電工程的建設(shè)快速發(fā)展。受地形地貌及其他因素的影響，許多擬建、在建和已建的大型水電站都選擇了地下廠房的形式。由于水電站一般為深埋地下廠房，不受陽光照射，且圍護(hù)結(jié)構(gòu)表面散濕較大，其空氣相對(duì)濕度也往往較大。特別是水電站的水輪機(jī)層和蝸殼層，相對(duì)濕度甚至達(dá)到90%以上，廠房中常常發(fā)生結(jié)露現(xiàn)象。潮濕的地下空間不但會(huì)影響機(jī)電設(shè)備的使用壽命，而且對(duì)工作人員的健康也產(chǎn)生不利影響。 本課題對(duì)地下廠房的濕環(huán)境進(jìn)行了深入的理論分析，，對(duì)已建成的惠州抽水蓄能電站地下廠房的熱濕環(huán)境進(jìn)行夏季現(xiàn)場(chǎng)測(cè)試，并對(duì)地下廠房的濕環(huán)境進(jìn)行了詳細(xì)的數(shù)值模擬，分析了水電站地下廠房除濕機(jī)實(shí)際運(yùn)行中存在的問題。通過對(duì)惠州抽水蓄能電站A廠房和B廠房（A廠房和B廠房裝機(jī)容量、洞室結(jié)構(gòu)完全一樣，只是B廠房水輪機(jī)層裝了13臺(tái)除濕機(jī)，A廠房未裝除濕機(jī)）水輪機(jī)層的熱濕環(huán)境現(xiàn)場(chǎng)對(duì)比測(cè)試分析和數(shù)值模擬，研究了除濕機(jī)的有效除濕半徑和有效除濕范圍。推薦了水電站地下廠房除濕機(jī)的合理設(shè)計(jì)及布置方案。
[Abstract]:In recent years, our country vigorously develops hydropower resources, and the construction of hydropower projects develops rapidly.Under the influence of topography and other factors, many large hydropower stations proposed to be built, are under construction and have been built have chosen the form of underground powerhouse.Because the hydropower station is usually a deep buried underground powerhouse, it is not exposed to sunlight, and the surface of the enclosure structure is wet, and the relative humidity of the air is often higher.Especially, the relative humidity of turbine layer and volute layer of hydropower station is more than 90%.Damp underground space will not only affect the service life of mechanical and electrical equipment, but also adversely affect the health of staff.In this paper, the wet environment of underground powerhouse is analyzed theoretically, the thermal and wet environment of the underground powerhouse of Huizhou pumped storage power station is tested in summer, and the wet environment of underground powerhouse is simulated in detail.The problems existing in the practical operation of dehumidifier in underground powerhouse of hydropower station are analyzed.According to the installed capacity of the A and B power plants of Huizhou pumped Storage Power Station, the structure of the caverns is exactly the same.Only 13 dehumidifiers and no dehumidifiers have been installed in the turbine layer of Factory B) the thermal and wet environment of the turbine layer has been tested and analyzed numerically, and the effective dehumidification radius and the effective dehumidification range of the dehumidifier have been studied.The reasonable design and layout of dehumidifier for underground powerhouse of hydropower station are recommended.
