Cleaning method of centrifugal sprinkler for centrifugal spray dryer

The cleaning method of centrifugal sprinkler for centrifugal spray dryer after we use the centrifugal spray dryer equipment, in order to ensure the next normal use, we need to clean and maintain its centrifugal sprinkler Then, when you clean the centrifugal spray dryer's centrifugal sprinkler, do you know what methods can be adopted? Let's take a look at the specific content In fact, we can choose different methods according to the specific circumstances, so as to complete the cleaning of centrifugal sprinklers in centrifugal spray dryer At present, there are three main cleaning methods, namely dry cleaning, wet cleaning and chemical cleaning Among them, chemical cleaning method can also be divided into alkaline solution, acid solution and cleaning of various detergents The so-called dry cleaning mainly refers to the use of brushes, brooms, vacuum cleaners and other cleaning So, what is wet washing? The so-called wet washing, in fact, refers to the use of hot water in the range of sixty to eighty degrees Celsius for centrifugal spray dryer spray nozzle cleaning Alkali washing refers to the preparation of sodium hydroxide (NaOH) into a solution of 0.5-1% concentration, then heating to 60-80 ℃, washing it, and then using clean water after cleaning In addition, the so-called pickling mainly refers to the preparation of (HNO3) solution at a concentration of 1-2% and heating it At this time, it should be noted that the heating temperature should not exceed 65 ℃ After that, the centrifugal sprinkler of the centrifugal spray dryer was washed, and then rinsed clean with water after Zui It should be noted that after the completion of wet washing and chemical washing, all parts of the equipment need to be installed and sterilized at high temperature The sterilization time is about 15-30 minutes During the cleaning process, attention should be paid to the protection of the centrifugal sprinkler of the centrifugal spray dryer In particular, chlorine and its compounds should not be used for washing, so as to avoid oxidation In short, when cleaning the centrifugal sprinkler of centrifugal spray dryer, we should not only pay attention to cleaning up, but also prevent it from being adversely affected.
