Description

Technical Field

[0001] The present invention mainly relates to the field of activated carbon utilization, and in particular to a heating treatment device for waste activated carbon utilization. Background Art

[0002] Activated carbon is made by activating carbon-containing materials such as wood, coal, and fruit shells under high temperature and oxygen-deficient conditions. Activated carbon adsorption is a water treatment method that uses the physical adsorption, chemical adsorption, oxidation, catalytic oxidation, and reduction properties of activated carbon to remove pollutants from water. Heating regeneration is the most widely used method for the reuse of activated carbon and the most mature activated carbon regeneration method in industry. During the regeneration process of activated carbon, according to the changes of organic matter when heated to different temperatures, it is generally divided into three stages: drying, high-temperature carbonization and activation. In the drying stage, the volatile components on the activated carbon are mainly removed. In the high-temperature carbonization stage, part of the organic matter adsorbed on the activated carbon is boiled, vaporized and desorbed, and part of the organic matter undergoes decomposition reaction to generate small molecular hydrocarbons and desorb, and the residual components remain in the pores of the activated carbon to become "fixed carbon". In this stage, the temperature will reach 800-900°C. In order to avoid oxidation of activated carbon, it is generally carried out under vacuum or inert atmosphere. In the following activation stage, gases such as CO2, CO, H2 or water vapor are introduced into the reactor to clean the micropores of the activated carbon and restore its adsorption performance. The activation stage is the key to the entire regeneration process.

[0003] The inventor discovered the following defects during the operation of the specific embodiment: However, due to the large size of activated carbon, when the large activated carbon is placed in the heating treatment device for heating, the temperature difference between the inside and outside of the activated carbon is large, and subsequent gases such as CO2, CO, H2 or water vapor cannot enter the interior of the activated carbon or enter the interior of the activated carbon at a slow speed, affecting the adsorption capacity of the activated carbon after reuse, and the waste activated carbon is directly accumulated inside the heating treatment device, which is also easy to cause uneven heating of the waste gas activated carbon.
