Description
После 360 ч осадка After 360 h of sediment
в коммуникаци х практически не было.there was practically no communication.
Пример 2. В бак дл приготовлени промывного раствора подают кислые воды после промывки фильтровального .полотна, содержащие 20 г/л иона Р04. В этот же бак подают аммиачный конденсат с содержанием NH4+ 1,2 г/л, РОг 2,5 г/л. Предварительно в аммиачиом конденсате раствор ют пыль моно- и диаммонийфосфата, котора вл етс отходом нроизводства аммофоса. Количества воды после промывки полотна и аммиачиого конденсата были вз ты в соотношении 1:1. За счет этого уменьшают вдвое расход чистой воды дл приготовлени промывного раствора. Промывной раствор после смешени содержит NH4+ 0,6 г/л, РОг 11,5 г/л. Этим раствором промывают осадок сульфата кальци в течение 240 ч.Example 2. Acidic water is fed into the tank for the preparation of the washing solution after washing the filtering cavity, containing 20 g / l of PO4 ion. Ammonia condensate containing NH4 + 1.2 g / l, ROg 2.5 g / l is fed to the same tank. The mono and diammonium phosphate dust, which is a waste product of ammophos, is dissolved in ammonia condensate beforehand. The amounts of water after washing the web and ammonia condensate were taken in a 1: 1 ratio. Due to this, the consumption of pure water is halved for preparing the washing solution. The wash solution after mixing contains NH4 + 0.6 g / l, ROg 11.5 g / l. This solution is washed with a precipitate of calcium sulfate for 240 hours.
При ревизии коммуникаций фильтра на стенках обнаружили лишь небольшой слой (0,2-0,5 мм) рыхлого осадка, т. е. практически коммуникации были чистыми.During the audit of the filter communications on the walls, only a small layer (0.2-0.5 mm) of loose sediment was found, i.e. practically the communications were clean.
Таким образом, предложенный раствор позвол ет интенсифицировать процесс за счет сокрашепи простоев.Thus, the proposed solution allows to intensify the process due to the contraction of downtime.
