Embodiment 1

[0052] Filter Disassembly: Separate the disc filter outer cylinder from the filter body.

[0053] Lift the decomposed filter into the TEG cleaning tank for cleaning.

[0054] TEG cleaning process parameters:

[0055] TEG liquid feeding time: about 15 minutes (stop when the TEG cleaning tank is also high).

[0056] N before heating ２ Replacement: 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.

[0057] TEG cooling method: air cooling. TEG cooling time to 90°C: 4 hours.

[0058] When cooling down N ２ Protection: Recharge N every 20 minutes ２ , each charging time is 30 seconds, and the N charging is ended when the discharge temperature is reached ２ .

[0059] After cleaning, lift the filter out of the cleaning tank and enter it into the chemical cleaning tank for cleaning.

[0060] Lift the filter lifted from the TEG cleaning tank into the ...

Abstract

The invention relates to a dish filter cleaning production line, which includes a filter disassembly machine, a TEG cleaning line, a chemical cleaning line, and a flushing assembly line; the filter disassembly machine is used to decompose the dish filter; the decomposed disc The type filter is sent to the TEG cleaning line for TEG cleaning; after the TEG cleaning is completed, it is sent to the chemical cleaning line for chemical cleaning; after the chemical cleaning is completed, it is sent to the washing assembly line for washing and assembly. In the dish filter cleaning production line provided by the present invention, TEG cleaning and chemical cleaning adopt circulation method and cleaning under pressure, and the TEG medium and chemical medium respectively enter into the disc of the dish filter under the action of pressure, which improves the cleaning effect. Increase the air cooling device to shorten the cooling time; increase the nitrogen replacement program to improve the safety of system operation.

Description

technical field [0001] The invention relates to a disc filter cleaning production line, which belongs to the field of equipment 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 he...
