【摘要】:采用先高溫后低溫的變溫干燥工藝降低碳化硅超細(xì)粉球團(tuán)的干燥成本,以干燥時(shí)間和單位能耗為指標(biāo),以變溫干燥的前期溫度、前期風(fēng)速、轉(zhuǎn)換干基含水率、后期風(fēng)速和后期溫度為主要影響因素進(jìn)行了L_(16)(4~5)正交實(shí)驗(yàn),研究了變溫干燥工藝,并結(jié)合多元回歸,根據(jù)多指標(biāo)權(quán)重進(jìn)行線性加權(quán)和優(yōu)化.結(jié)果表明,最佳優(yōu)化變溫干燥工藝參數(shù)為前溫期度200℃、前期風(fēng)速0.83 m/s、轉(zhuǎn)換干基含水率5%、后期風(fēng)速1.78 m/s、后期溫度140℃,該條件下干燥時(shí)間為203 min,單位能耗為65 MJ/kg.
[Abstract]:The drying cost of silicon carbide ultrafine pellets was reduced by using the variable temperature drying process of first high temperature and then low temperature. The drying time and unit energy consumption were taken as the index, and the temperature, wind speed and moisture content of dry base were changed. The orthogonal experiment was carried out to study the process of variable temperature drying, and combined with multiple regression, linear weighting and optimization were carried out according to the weight of multiple indexes. The optimum drying parameters are pre-temperature 200 鈩,
