Stainless steel sintering felt cleaning method, customers can choose according to your actual situation
Stainless steel sintered felt Because of its high strength, good rigidity, high temperature resistance, stable filtration efficiency, easy to clean and reuse, it is widely used in various industries. Among them, the cleaning method of stainless steel sintering felt is simple, saving time, so as to achieve 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 main cleaning methods of stainless steel sintered felt are as follows: ultrasonic cleaning, baking cleaning, backwater cleaning and filtrate cleaning.
Among them, ultrasonic cleaning and reverse water cleaning are common methods.
Reverse water cleaning method (also known as backwashing) is to backwash inert gas (such as nitrogen) to the opposite direction of normal filtration. Stainless steel sintered felt is particularly suitable for backwashing due to its relatively smooth and easy to clean. In addition, it is not necessary to remove it from the filter unit during the backwash process, and it can be cleaned directly in the filter unit. In order to carry out ultrasonic cleaning, it is necessary to take it out of the stainless steel sintered felt and clean it with an ultrasonic cleaner. Compared with backwashing, ultrasonic cleaning has a great impact on production efficiency, but ultrasonic cleaning is thorough, which can ensure the cleaning of filter unit.
There are three cleaning methods for stainless steel sintered felt: chemical cleaning, ultrasonic cleaning and heat treatment cleaning.
First of all, chemical cleaning 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 an energy wave that can be continuously pressurized and expanded. When it is applied to the liquid, cavitation is formed, and continuously ruptured cavities clean the sintered felt. This is the same as the principle of ultrasonic cleaning the sintering net.
After the heat treatment cleaning method is applied to the stainless steel sintered felt, the hair is usually cleaned when the chemical cleaning method is ineffective. Common heat treatment cleaning methods include vacuum pyrolysis, heating furnace, liquefying bed and hot salt bath.
Which cleaning method to use depends on the company's own production conditions and filter equipment conditions. The integrity of the stainless steel felt to be tested after sintering should be checked. The pressure drop and gender were measured.
