Key Points of Daily Operation Maintenance and Inspection of Solvent Liquefaction Recovery Unit

Direct answer:After the VOCs organic solvent liquefaction recovery device is put into operation, the core of daily operation is four things: watching parameters, listening to sounds, checking seals and recording data. Adhere to daily inspection, not only can keep the solvent recovery effect stable, but also can find the signs of failure in advance and reduce unplanned downtime.

List of 1. Inspection Items for Each Shift

1. Look at the operating parameters:Whether the inlet and outlet pressure of the compressor, the condensing temperature and the pressure difference before and after the membrane are within the design range.
2. Listen to the sound of the device:Whether the compressor unit has abnormal noise and vibration.
3. Check seals and leaks:There is no sign of solvent leakage at the pipe flange and valve packing, and there is no increase of peculiar smell on site.
4. Record running data:Parameter ledgers are recorded for each shift to facilitate trend comparison and problem tracing.

2. Periodic Maintenance Schedule

3. common minor problems self-troubleshooting

1. High condensation temperature:Most of the heat dissipation surface is dirty or the cooling medium is insufficient. Clean it first and then check it.
2. Increased membrane pressure difference:Check whether the front filter fails and whether the intake air has water.
3. Decreased recovery:Check whether it is concentration change or equipment attenuation according to the ledger, and judge it according to the intake working condition.

4. what circumstances need to contact the manufacturer

In case of aggravation of abnormal noise of compressor unit, abnormal fluctuation of system pressure, continuous over-standard discharge concentration and invalid self-investigation, it is recommended to contact the equipment manufacturer directly and do not run with diseases.

Frequently Asked Questions

Q: What does the inspection record need to include?
Answer: At least include the pressure and temperature, pressure difference, operation duration, abnormal conditions and treatment measures at each point. It is recommended to fill in the fixed form.

Q: Do operators need training?
Answer: It is required. The device involves compressor and pressure-bearing parts, and the operation and inspection personnel shall be trained on site by the manufacturer before taking their posts.

Q: What should I pay attention to when I stop and restart for a long time?
Answer: Before starting, check the lubricating oil state, electrical insulation and pipeline sealing. According to the manufacturer's regulations, turn the car first, then jog and then run.
