How to perform regular maintenance on the activated carbon adsorption box?
How to perform regular maintenance on the activated carbon adsorption box?Regular maintenance of activated carbon adsorption boxes can be started with the overall inspection of equipment, activated carbon performance maintenance, related parts maintenance, etc. The following is the specific maintenance content and key points:Inspection of overall appearance and connecting parts Appearance inspection: Regularly check whether the shell of the activated carbon adsorption box is corroded, deformed, or damaged. For the adsorption box installed in the open air, pay special attention to whether the anti-rust paint falls off, if the shell is found to have slight corrosion, it should be timely rust removed and re-painting treatment; If the parts are seriously deformed or damaged, repair or replace them in time. Check the connection parts: check the connection parts of the adsorption box, including flanges, bolts, pipe interfaces, etc., are firm, and there is no loosening, or leakage phenomenon. If the bolt is found loose, it should be tightened in time; For the leak, find the cause. The sealing gasket may be aging or damaged. Replace the sealing gasket in time. Active carbon performance maintenance Check the adsorption performance of activated carbon: The adsorption capacity of activated carbon can be tested regularly through professional testing equipment or methods. For example, the use of gas chromatography and other instruments to analyze the concentration of pollutants in the exhaust gas before and after adsorption to evaluate the adsorption effect of activated carbon. If the adsorption capacity is found to be significantly reduced, close to, or reach saturation, it is necessary to regenerate or replace the activated carbon in time. Check the status of activated carbon particles: Open the inspection port of the adsorption box to observe whether the activated carbon particles are broken and pulverized. If the pulverization is serious, it will lead to increased bed resistance and affect the adsorption effect, and the activated carbon should be supplemented or replaced in time. At the same time, pay attention to checking whether the activated carbon layer is stiffened, if so, it needs to be loosened or replaced. Air distribution system maintenance Check the air distribution device: Check whether the air distribution plate and guide blade in the adsorption box are damaged, deformed, or blocked. If it is damaged or deformed, it will lead to uneven distribution of airflow, affecting the adsorption effect, and should be repaired or replaced in time; For the blocked part, it is necessary to clean the dust and impurities above to ensure that the air can pass evenly. Optimize airflow uniformity: Airflow velocity at different positions of the adsorption chamber can be measured by equipment such as airflow velodrometer to evaluate airflow uniformity. If the airflow is found to be uneven, the Angle or position of the airflow distribution device can be adjusted, or the inlet and outlet of the adsorption box can be optimized to make the airflow evenly through the activated carbon bed. Maintenance of related parts Check the fan: Check the running status of the fan, including whether the speed, air volume, and pressure of the fan are normal, and whether there is abnormal noise and vibration. Clean the fan regularly, clean the dust and debris on the impeller, and prevent the vibration of the impeller from being aggravated by the imbalance. At the same time, check the bearing, belt, and other parts of the fan, timely supplement or replace the lubricating oil, and adjust the tightness of the belt. Maintain the differential pressure gauge: check whether the display of the differential pressure gauge is accurate and whether the connection pipe is smooth. Calibrate the differential pressure gauge regularly to ensure that it accurately reflects the pressure drop in the adsorption chamber. If the differential pressure meter is found to be faulty, it should be repaired or replaced in time. Clean the filter: If there is a filter in front of the adsorption box, it is necessary to regularly clean or replace the filter material to prevent the filter blockage resulting in reduced air intake, affecting the adsorption effect. Electrical control system maintenance Check electrical components: Check the electrical components in the electrical control cabinet, such as contactors, relays, circuit breakers, etc., whether they work normally, and whether there is overheating or ignition. Check whether the wiring of each electrical component is firm and whether there is a loosening and aging phenomenon. Aging or damaged electrical components should be replaced in time; Loose wires should be reconnected securely. Test the control system: check whether the functions of the control system are normal, such as automatic switching, alarm function, etc. Test the control system regularly, simulate the fault situation, check whether the alarm device can send an alarm in time, whether the automatic switching device can work normally, and ensure that the adsorption box can be handled in time when there is an anomaly. In addition, record the maintenance time, maintenance contents discovered problems, and handling results in detail for subsequent maintenance and device operation management. |
