【摘要】：晶種分解的原理是指在過飽和的鋁酸鈉溶液(精液)中添加晶種、降溫并不斷攪拌分解析出Al(OH)3的過程。通過板式換熱器充分換熱后,降低精液溫度提高種分母液溫度。板式換熱器精液相在降溫的過程中水解產(chǎn)生結(jié)疤,板式換熱器需頻繁堿洗才能保證其正常換熱。本文通過對板式換熱器換相閥的應(yīng)用實(shí)踐研究其可行性,提高板式換熱器換熱效率,穩(wěn)定分解條件。
[Abstract]:The principle of seed decomposition refers to the process of adding seed to supersaturated sodium aluminate solution (semen), cooling down and continuously stirring and precipitating Alo OH3. After full heat transfer through plate heat exchanger, the temperature of seed mother liquor can be increased by lowering semen temperature. In the process of cooling down the semen phase of plate heat exchanger produces scarring. The plate heat exchanger needs frequent alkali washing to ensure its normal heat transfer. In this paper, the feasibility of the application of the commutation valve in plate heat exchanger is studied in order to improve the heat transfer efficiency of the plate heat exchanger and to stabilize the decomposition conditions.
