L-217實(shí)驗(yàn)室高性能噴霧干燥機(jī)是使液態(tài)物料經(jīng)過噴嘴霧化成細(xì)微的霧狀液滴，以獲得大的比表面積，在進(jìn)入干燥塔內(nèi)流動(dòng)的熱力場(chǎng)后，霧狀液滴立即被干燥并分離為粉料的熱力過程。進(jìn)料可以是溶液、乳濁液、懸浮液、糊狀物、膠狀液體等可流動(dòng)的液體。噴霧干燥技術(shù)是干燥領(lǐng)域發(fā)展快、應(yīng)用范圍廣的一種干燥方式，目前被廣泛應(yīng)用于醫(yī)藥工業(yè)、食品工業(yè)、化學(xué)工業(yè)、乳品工業(yè)、建材工業(yè)、染料工業(yè)等。L-217實(shí)驗(yàn)室高性能噴霧干燥機(jī)特點(diǎn)：數(shù)顯清晰：采用大字?jǐn)?shù)碼管顯示實(shí)驗(yàn)參數(shù)，方便遠(yuǎn)距離對(duì)實(shí)驗(yàn)參數(shù)的觀察、監(jiān)測(cè)及調(diào)整。
參數(shù)不穩(wěn)定的煙氣余熱鍋爐煙氣在流量、溫度、成份組成、含塵量等各方面的波動(dòng)是其特征之一，波動(dòng)的性質(zhì)可以是有規(guī)律的、周期性的，也可以是非規(guī)律性、非周期性的；波動(dòng)的特點(diǎn)可以是漸進(jìn)性的、也可以是沖擊性的；可以是單一參數(shù)的，也可以是多參數(shù)的復(fù)合性波動(dòng)。余熱鍋爐的選型必須首先分析主工藝流程的整個(gè)周期，確定周期中各個(gè)時(shí)間區(qū)段的煙氣特點(diǎn)，從而在余熱鍋爐設(shè)計(jì)中逐個(gè)落實(shí)相應(yīng)的措施。其中突出的特點(diǎn)往往是余熱鍋爐選型的主要根據(jù)。
超聲波清洗設(shè)備的頻率應(yīng)該在生產(chǎn)廠商所建議的范圍內(nèi)，用經(jīng)多次所得的佳頻率進(jìn)行清洗。超聲波頻率越高，液體內(nèi)氣泡的體積越小，強(qiáng)度也越弱，一般推薦使用的頻率為4KHz，在此頻率下，會(huì)產(chǎn)生小的氣泡深入網(wǎng)穴進(jìn)行清洗.不過，由于網(wǎng)紋輥的性質(zhì)及超聲波清洗設(shè)備設(shè)計(jì)不同，此頻率推薦值僅供參考。。清洗劑的溫度也會(huì)影響到清洗質(zhì)量，溫度高，清洗劑黏度就低，液體中的氣泡量就會(huì)增加，從而增加超聲波清洗的能力。
