Embodiment 1
[0059] Filter Disassembly: Separate the disc filter outer cylinder from the filter body.
[0060]Lift the decomposed filter into the TEG cleaning tank for cleaning.
[0061] TEG cleaning process parameters:
[0062] TEG liquid feeding time: about 15 minutes (stop when the TEG cleaning tank is also high).
[0063] N2 replacement before heating: 0.15MPa three times, 1 minute each time) heating, heat preservation and cleaning: 7 hours. Cleaning temperature: 275°C. Cleaning pressure: 0.23MPa. Temperature uniformity: ±1°C.
[0064] TEG cooling method: air cooling. TEG cooling time to 90°C: 4 hours.
[0065] N2 protection when cooling down: charge N2 every 20 minutes, each charge time is 30 seconds, and stop charging N2 when the discharge temperature is reached.
[0066] After cleaning, lift the filter out of the cleaning tank and enter it into the chemical cleaning tank for cleaning.
[0067] Lift the filter lifted from the TEG cleaning tank into the chemical cleaning tank....

The invention relates to a disk-type filter cleaning technology which includes following steps: (1) disassemble of the filter: separating an external cylinder body of a disk-type filter from a filter main body; (2) hanging the disassembled filter into a TEG cleaning sink for cleaning the filter; (3) hanging the filter out from the cleaning sink after the cleaning process is over and then placing the filter into a chemical cleaning sink for cleaning the filter; (4) taking out a disk from the filter which is cleaned in the TEG cleaning process and the chemical cleaning process; (5) performing a high-pressure water-washing process to the disk; (6) performing an ultrasonic cleaning process to the disk which is washed in the high-pressure water-washing process and performing a drying process after the ultrasonic cleaning process; and (7) assembling the disk into the filter after the drying process to complete the cleaning technology.
Description
technical field [0001] The invention relates to a dish filter cleaning process, which belongs to the field of cleaning. Background technique [0002] The existing disc filter adopts the triethylene glycol (TEG) washing method, that is, put the disc filter into a cleaning furnace with an electric heater at the bottom, close the furnace cover, and clean it at a temperature of 275°C About 10 hours, then naturally cool in the furnace to below 90°C (cooling time is about 12 hours), take out the filter, and then wash with water, alkali wash, pickle wash, high-pressure water gun rinse, ultrasonic cleaning, disc drying, Filter assembly. The entire cleaning process is non-circular cleaning under normal pressure. As the number of cleanings increases, the concentration of the triethylene glycol medium becomes thinner and dirtier. At the same time, because the heater of the cleaning furnace is at the bottom of the equipment, the equipment is effective The cleaning height is above 2.5m...
