【摘要】：建立了無填料冷卻塔試驗(yàn)平臺(tái),研究了不同進(jìn)風(fēng)位置、氣水比、室外空氣干球溫度、循環(huán)水進(jìn)水溫度下無填料冷卻塔冷卻性能的變化規(guī)律。結(jié)果表明:上噴式無填料冷卻塔上進(jìn)風(fēng)時(shí)冷卻效率優(yōu)于下進(jìn)風(fēng),下噴式無填料冷卻塔下進(jìn)風(fēng)時(shí)冷卻效率優(yōu)于上進(jìn)風(fēng);氣水比升高冷卻效率升高,但氣水比達(dá)到1.8后,繼續(xù)提高氣水比冷卻效率增速降低;室外空氣干球溫度升高,冷卻效率降低;進(jìn)水溫度升高冷卻塔冷卻效率均得到提高,但上噴式冷卻塔冷卻效率的提高明顯大于下噴式冷卻塔。
[Abstract]:A test platform for unpacked cooling tower was set up to study the change of cooling performance of cooling tower with different inlet air position, air-water ratio, outdoor air dry ball temperature and circulating water inlet temperature. The results show that the cooling efficiency of the upper jet type unfilled cooling tower is better than that of the bottom air inlet air, and the cooling efficiency of the bottom air inlet air is better than that of the bottom air inlet air, and the air-water ratio increases, but when the gas-water ratio reaches 1.8, the cooling efficiency is better than that of the lower air inlet. Continue to increase the air-water specific cooling efficiency, increase the outdoor air dry ball temperature, reduce cooling efficiency, increase the inlet water temperature, increase cooling efficiency of cooling tower, However, the cooling efficiency of the upper jet cooling tower is obviously higher than that of the lower jet cooling tower.
