How to prevent the hidden trouble of rotary dehumidifier?

Author:Lianzhong | Release time:2021-06-17

There are risks in the application of rotary dehumidifier equipment, except for rotary dehumidifier equipment. Therefore, good maintenance and preventive measures should be taken to ensure the full application and characteristics of the rotary dehumidifier equipment and reasonably extend its service life.

1. Avoid excessive steam intake in the rotary dehumidifier: the reheater valve should always be implemented, the steam turbine generator unit should invest money in the braking equipment, and clamp the check valve of the pressure cylinder exhaust pipe, so as to avoid excessive steam intake in the heating furnace due to improper closing of the valve.

2. Avoid overheating and overpressure: during the adjustment of steam boiler valve, the ignition adjustment should be improved to avoid overpressure accident; When the power switch is bypass and the filling gun is stopped, the working pressure must be stable. The criteria of bypass regulation are: the small opening on the high side should ensure that the reheater does not overheat, and the small opening on the low side should ensure that the reheater does not overheat; In order to avoid unexpected overpressure in the whole valve regulation process of gas-fired steam boiler, PCV (magnetic induction release valve) should ensure reliable manual power switch.

3. Avoid uneven bearing capacity of seismic bearing: send full-time personnel to check the bearing capacity of seismic bearing during the whole process of temperature rise and pressure rise. If it is found that the bearing capacity of the anti-seismic bearing is obviously uneven or abnormal (such as large vibration) compared with the rotary dehumidifier equipment, it should be adjusted immediately.

4. Avoid steam leakage: strengthen on-site inspection and pay attention to the tightness of welds, handholes, manholes and flanges of the rotary dehumidifier.

5. Common problems on site: adjust the address, lighting lamps should be sufficient, road surface should be smooth, avoid steam ejection after valve posture, and irrelevant personnel are forbidden to stay; There is a reliable and convenient communication system between the rotary kiln and the control room to keep in touch with each other. All personnel should cooperate closely and obey the command.

Because the risk of the wheel dehumidifier is very serious, the actual operators should pay special attention to observe, ensure the normal application of the equipment of the wheel dehumidifier, and do the inspection of the equipment of the runner dehumidifier on time. Once there are common faults, they should be dealt with immediately to prevent endangering the utilization rate of rotary dehumidifier equipment.
