AI Technical Summary

Problems solved by technology

The disadvantage of this type of adsorption and recovery device is: because the exhaust gas adsorption device uses activated carbon fibers wrapped around the adsorption core, and when water vapor is desorbed, the water stays in the activated carbon fibers, which reduces the adsorption efficiency. The drying equipment obviously increases the equipment cost and operating cost; at the same time, due to the large airflow resistance of the activated carbon fiber, the high-temperature steam is unevenly distributed in the adsorption tank. In order to prevent the inner wall of the tank from rusting, the adsorption tank is mostly made of expensive stainless steel. The large airflow resistance also increases the power of the fan matched with the device, so the production cost and operating cost are higher
