The cleaning method of stainless steel sintered felt, choose right way according to your actual situation.
Stainless steel sintered felt is widely used in various industries due to its high strength, good rigidity, high temperature resistance, stable filtration efficiency, easy cleaning and reuse. Among them, the method of cleaning stainless steel sintered felt is simple, saves time, and achieves high recycling efficiency, which is a common concern of customers. Now, we introduce several cleaning methods of stainless steel sintered felt, customers can choose according to your actual situation!
The cleaning of stainless steel sintered felt mainly includes the following methods: ultrasonic cleaning method, baking cleaning method, reverse water cleaning method and filtrate cleaning method.
Among them, ultrasonic cleaning method and reverse water cleaning method are more common methods.
The reverse water cleaning method (also known as backwashing) is to backwash an inert gas (such as nitrogen) to the opposite direction of normal filtration. Stainless steel sintered felt is particularly suitable for backwashing due to its relative smoothness and ease of cleaning. Furthermore, it does not have to be removed from the filter unit during backwashing and can be cleaned directly in the filter unit. For ultrasonic cleaning, it needs to be removed from the stainless steel sintered felt and cleaned with an ultrasonic cleaner. Compared with backwashing, ultrasonic cleaning has a great impact on production efficiency, but ultrasonic cleaning is thorough and can ensure the cleaning of filter units.
There are three cleaning methods for stainless steel sintered felt: chemical cleaning method, ultrasonic cleaning method and heat treatment cleaning method.
First of all, chemical cleaning method is a common cleaning method of acid-base cleaning solution, which can be used to clean and collect stainless steel sintered felt.
Then there is the ultrasonic cleaning method. Ultrasound is a wave of energy that can be continuously pressurized and expanded. When it is applied to a liquid, air pockets are formed, and the continuously broken air pockets clean the sintered felt. This is the same principle as cleaning the sintered mesh with ultrasonic waves.
After applying heat treatment cleaning methods to stainless steel sintered felts, hair is usually washed when chemical cleaning methods are ineffective. Common thermal cleaning methods include vacuum pyrolysis, furnaces, fluidized beds, and hot salt baths.
Which cleaning method is used for cleaning depends on the company's own production conditions and the conditions of the filter equipment. It should be noted that after cleaning the stainless steel sintered felt, a bubble point test is required to check its integrity. gender and measure pressure drop.
