Activated carbon regeneration refers to a physical or chemical method that removes the adsorbent adsorbed on activated carbon without destroying the original structure of activated carbon, thereby restoring its adsorption performance and achieving the purpose of reuse.
The state encourages all industries to pay attention to and strengthen the reuse of waste generated in production and life. As a widely used adsorbent, activated carbon has a considerable annual usage in various industries. The reuse of regenerated saturated activated carbon has strong economic and environmental benefits and is supported and encouraged by national policies.
1. It is conducive to circular economy
The application scope of activated carbon is becoming more and more extensive, but because activated carbon is easily saturated and loses its adsorption capacity during use, it must be replaced frequently to achieve the use effect. Activated carbon is expensive, and each replacement of new carbon will increase the operating cost of the enterprise, so it is necessary to consider the regeneration of saturated activated carbon to achieve the purpose of circular economy.
2. It is conducive to energy conservation and emission reduction
If 1 ton of saturated activated carbon is incinerated as waste, it is equivalent to releasing 0.128 tons of carbon dioxide into the atmosphere. To produce 1 ton of high-quality activated carbon, 8 tons of wood or 8 tons of raw coal are needed. The regeneration of activated carbon can greatly reduce the consumption of coal resources, reduce air pollution, and reduce energy waste.
The powdered activated carbon regeneration kiln is the main equipment for the regeneration of powdered activated carbon. The powdered activated carbon regeneration kiln designed by our company adopts external combustion furnace heating, which has high thermal energy. Since the activated carbon is not directly heated inside the kiln body, but the activated carbon is sealed inside the kiln body, the spontaneous combustion loss of powdered activated carbon is reduced. The discharge hood relies on the heavy hammer to generate axial compression force, so that the sealing packing presses the dynamic sealing plate to achieve a sealed connection between the rotating rotary kiln body and the stationary discharge hood, thereby isolating the entry of air and achieving a sealing effect, thereby preventing the spontaneous combustion of activated carbon in the activation of air, and improving the regeneration activation rate of activated carbon. A strip hole is opened on the fixed plate to reserve a certain space for the expansion and contraction of the lifting plate. When the lifting plate is extended, the elongation due to the expansion of the lifting plate can be eliminated through the strip hole, avoiding the thermal expansion and breaking of the lifting plate, and reducing the equipment maintenance cost.
