The maintenance of activated carbon processing machinery should be carried out comprehensively from multiple aspects such as daily inspection, maintenance of key components, fault handling, activated carbon replacement and safety protection. The following are the specific steps:

I. Daily Inspection

Visual inspection: Check the appearance of the equipment daily for any damage, corrosion, leakage or other conditions. Special attention should be paid to inspecting the connection parts and pipe interfaces of the equipment to ensure good sealing.

Operation parameter inspection: Closely monitor the operation parameters of the equipment, such as adsorption temperature, pressure, flow rate, etc., to ensure that these parameters are within the designed operation range of the equipment.

Instrument inspection: Check whether all types of instruments (such as pressure gauges, thermometers, flow meters, etc.) are working properly and whether the displayed data is accurate.

Clean the equipment: Regularly clean the dust, dirt, etc. inside and outside the equipment to prevent their accumulation and affect the performance of the equipment. For internal structures such as adsorption beds, compressed air or vacuum cleaners can be used for cleaning.

Ii. Maintenance of Key Components

Fan maintenance

Regularly check whether the fan is operating normally to prevent it from being damaged due to excessive temperature.

The fan should be maintained and serviced annually to ensure that the insulation resistance value of the motor meets the requirements.

Ventilation system maintenance

The ventilation system is an important part to ensure the normal operation of the activated carbon adsorption equipment. It is necessary to regularly clean the accumulated dust in the ventilation ducts.

Check the operating condition of the fan to ensure smooth ventilation.

Electrical system maintenance

Professional electricians should regularly inspect the electrical system of the equipment, including wires, cables, control cabinets, etc.

Ensure that the electrical connections are firm and free from potential safety hazards such as leakage and short circuits.

Iii. Fault Handling

Timely handling of faults: Once a malfunction of the equipment is detected, such as a decline in adsorption efficiency or damage to equipment components, the machine should be immediately shut down for inspection. Analyze the cause of the fault and promptly carry out repairs or replace the damaged components.

Record fault information: Make detailed records of the occurrence time, phenomenon, cause and maintenance measures of each fault to provide references for subsequent maintenance and equipment improvement.

Iv. Replacement of Activated Carbon

Judgment of activated carbon saturation

The adsorption effect of activated carbon can be judged by detecting the concentration of pollutants in the gas or liquid after adsorption. When the concentration of pollutants after adsorption significantly increases, approaching or exceeding the emission standards, it indicates that the adsorption capacity of activated carbon is close to saturation and needs to be replaced.

Estimate the service life of activated carbon based on the operating time and processing capacity of the equipment. Generally speaking, under normal operating conditions, the service life of activated carbon is 6 to 12 months, but the specific lifespan still needs to be determined based on factors such as the types and concentrations of pollutants actually being treated.

Open the equipment and observe the appearance of the activated carbon. If you find that the color of the activated carbon has significantly darkened, there is a large amount of dirt adhering to the surface, or there are phenomena such as lumps and powdering, you should also consider replacing the activated carbon.

Activated carbon replacement operation

Preparations: Prepare the necessary tools and new activated carbon in advance, and ensure that the model and specification of the new activated carbon are consistent with the original one. At the same time, prepare protective equipment such as gloves, masks, and goggles to prevent contact with harmful substances during the replacement process.

Remove the old activated carbon: During the removal process, be careful to avoid the dust of the activated carbon flying around. Try to clean all the old activated carbon thoroughly, including the corners and crevices of the adsorption bed.

Clean the interior of the equipment: After removing the old activated carbon, thoroughly clean the interior of the equipment to remove any remaining activated carbon particles, dust, and dirt, etc.

Loading new activated carbon: Evenly load the new activated carbon into the adsorption bed or adsorption tank. Pay attention to the moderate filling density to avoid the occurrence of lumps or excessive voids. During the filling process, the equipment can be vibrated appropriately to make the activated carbon fill more tightly.

Inspection and Sealing: After filling is completed, check if there are any foreign objects inside the equipment. Once confirmed to be correct, close the replacement port or maintenance door and carry out sealing treatment to ensure there is no leakage in the equipment.

Commissioning and operation: Start the equipment, gradually adjust the operating parameters to the normal state, observe the operation status and adsorption effect of the equipment, and ensure that the new activated carbon can work normally.

V. Safety Protection and Environmental Protection Treatment

Safety protection

During the maintenance and replacement of activated carbon, it is essential to strictly follow the safety operation procedures and wear protective equipment properly.

When the equipment is in operation, the maintenance door must not be opened. If maintenance is required, the fan must be turned off first. Non-engineering and technical personnel are not allowed to modify the equipment by themselves.

Environmental protection treatment

The old activated carbon that has been replaced is classified as hazardous waste and should be properly handled in accordance with environmental protection requirements. It must not be discarded at will.

Waste activated carbon can be treated by incineration, landfill or handed over to professional disposal units for processing. During the processing, regular monitoring is required to ensure that the disposal does not cause secondary pollution to the environment.
