To ensure safety, meet environmental functions, and regulatory compliance, it is basically whether your factory's wet scrubber can pass regular operation. Maintaining normal operations requires routine protection, including routine preventive maintenance, planned preventative maintenance, and sometimes mandatory maintenance.
The necessity of maintenance
Wet scrubbers play a vital role in any industrial equipment that uses them. They remove impurities from the air stream to maximize potentially harmful pollutants released into the adjacent environment. This function is beneficial to the maintenance of workers, the public, and the environment.
To achieve the joint operation to complete the normal process at the necessary level, it is essential to draw up a wet scrubber maintenance plan. Because the wet scrubber plays a vital role in the factory's operation, the wet scrubber's maintenance is also essential because it enables the wet scrubber to correctly and reliably supplement its functions.
Also, the packed bed scrubber is maintained regularly, and its efficient operation is supported. If maintenance is not routinely scheduled, the wet scrubber may consume more energy, thereby increasing costs, Putting security, environmental utility, and compliance at risk.
Previous costs will accompany preventive maintenance, but these costs can help avoid more future expenditures. Scheduled preventive care can help reduce costs and recovery risks.
Preventive maintenance of conventional wet scrubbers
To ensure the scrubber's efficient and safe operation, you need to maintain the industrial scrubber once every day, every week, every quarter, and every six months and insist on the completion of the maintenance operation records. You may need to create a wet scrubber maintenance checklist to assist in the step-by-step necessary maintenance check. Some essential tasks to include are:
Daily wet scrubber maintenance mission
You should monitor and alert the following measures so that you can keep paying attention to the top of the brakes:
Airflow in the piping system
Pressure drop in scrubber and demister
Check these measured values at least once a day and set up a system to assume that one of the measured values exceeds the equipment's average operating scale and announces an alarm.
If the measured value exceeds your equipment's average operating scale, maintenance is required to allow it to recover usually. Each device should define its average functional scale for pressure drop.
Checking and, when necessary, calibrating the pH in the wet scrubber is another central daily task in the maintenance of packed bed scrubbers. Always look at the pH. If it changes the ideal level, add alkali very slowly to adjust it as needed. If your factory uses an automatic dosing system, please check it regularly to ensure its regular operation.
Because the demister is not working correctly, the operator should also check whether the chimney and the area near the vent are aligned and hidden from the beginning. The traces sought include:
The chimney and adjacent areas' discoloration.
The volume of solids.
The mud lips around the chimney.
If the operator finds that it has been trapped again, he must quickly correct the problem.
Weekly wet scrubber maintenance
The wet scrubber's weekly maintenance should include checking the hydraulic gauge on the scrubber supply header to check for separation of titles, nozzle insertion, and nozzle corrosion. Exceeding the normal pressure indicates an overlap problem, and exceeding the normal pressure means a corrosion problem.
Every Wednesday, you also need to drain and clean the sump and refill it with clean water. As you step through these tasks, look at the sump.
Quarterly Wet Scrubber Maintenance Tasks
Once a quarter, you should inspect the entire system to check for leaks. If any leaks are found, it's essential to fix them quickly.
Semi-Annual Wet Scrubber Maintenance Tasks
Semi-annually, perform an internal inspection of the wet scrubber and check for signs of corrosion, erosion, plugged or eroded spray nozzles, solids deposits in tray orifices, and packed beds and solids accumulation in mist eliminators.
