Cleaning of filter elements for petrochemical use
Thread Content
The diagram here shows the filter elements used commonly in the petroleum and chemical industries; they are primarily used to remove solid particles from products, thereby improving product quality. The pore size of the filter tube is 20 microns, and it must be cleaned after about half a year of use. A filter element costing 3,000 yuan is used in each piece of equipment, which costs around 2 million yuan. According to the regulations, the regular cleaning of each one costs about 500 yuan; each unit can be cleaned only 3 times before it needs to be discarded. Cleaning is carried out by combining alkaline high-temperature degreasing with high-pressure water jet technology; the cost per piece is 100 yuan, and there is no limit on the number of cleaning cycles.
Mr. Wang, do you mean pickling when you talk about regular cleaning? In a similar situation, have you considered using ultrasonic cleaning? Actually, one can do it oneself by creating a resonance device that generates low-frequency vibrations! :victory:
When the material permits, is it better to cool it down before resonance?
Commercial cleaning involves ultrasonic cleaning, chemical cleaning, and high-temperature sintering cleaning; it can only be done 2 times； Second, the price is on the high side. I use high-pressure water jet technology combined with alkaline cleaning at a certain temperature only on filters that are already discarded, and the results are good. After cleaning, those that have been scrapped are no different from new ones.
Because the scale resulting from coking of the filter elements is quite difficult to remove, and only those who work with them can understand this.
Mr. Wang, you’re turning waste into treasure here! With more people like you in businesses, how could anyone not be happy?
If anyone is interested, I have a detailed summary report that I can provide free of charge for reference.
