How long is the service life of the activated carbon adsorption box?
How long is the service life of the activated carbon adsorption box?The service life of an activated carbon adsorption box is affected by a variety of factors, generally in 3 to 5 years, but through reasonable maintenance and replacement of activated carbon and other operations, can extend its service life, the following is the specific analysis:Effect of activated carbon Exhaustion of adsorption capacity: The core of the activated carbon adsorption box is activated carbon, which adsorbs pollutants through the micro-pore structure on the surface. When the micropores on the surface of the activated carbon are filled with pollutants and the adsorption capacity reaches saturation, the activated carbon needs to be replaced. If the concentration of waste gas or wastewater pollutants is high and the flow rate is large, the time for activated carbon to reach saturation will be shorter, and it may need to be replaced in a few months; In the case of low pollutant concentration and small flow, the service life of activated carbon may be extended to 1 to 2 years. Activated carbon quality: Different qualities of activated carbon, its specific surface area, pore structure, and other characteristics are different. High-quality activated carbon has a larger specific surface area and a richer pore structure, stronger adsorption capacity, and relatively long service life, and may be used in normal conditions 1.5 to 2 years before replacement; Inferior activated carbon may lose its effect in a few months. Equipment structure and material Structural design: Reasonable structural design can make the waste gas or wastewater evenly distributed in the adsorption box so that the activated carbon can fully play the adsorption role and extend the overall service life. If the structure design is not reasonable, it may lead to excessive adsorption of local activated carbon, and insufficient adsorption of other parts, so that the overall performance of the equipment is reduced, and the service life is shortened. Material quality: The material of the adsorption box determines its corrosion resistance, sealing, and other properties. If the use of corrosion-resistant, high-strength materials, such as stainless steel, the adsorption box can maintain good performance in harsh environments, and the service life can reach 5 years or more; If the ordinary material is used, it may be damaged in 2 to 3 years due to corrosion, aging and other problems. Operating environment and maintenance Operating environment: If the operating environment temperature is too high or too low, humidity is too large, etc., it will affect the adsorption performance of activated carbon and the stability of the equipment. For example, in high temperature and high humidity environments, activated carbon may undergo hydrolysis and other reactions, reducing the adsorption capacity, while the equipment is also more prone to corrosion and other problems so the service life is shortened to 2 to 3 years. Maintenance: Regular inspection, cleaning, and maintenance of the activated carbon adsorption box, such as timely cleaning of impurities in the adsorption box, regular detection of the adsorption performance of activated carbon, and timely replacement of activated carbon, etc., can keep the equipment in good running condition and extend the service life. |
