Activated carbon regeneration equipment and process adopting rapid airflow activation oven

Abstract

The invention discloses activated carbon regeneration equipment and process adopting a rapid airflow activation oven. The regeneration process comprises steps as follows: waste saturated activated carbon as a raw material is subjected to constant-temperature drying, moisture is controlled to be 15%-18%, and then the raw material enters a standby bin; the airflow activation oven is started, an oven head is pushed by fans, an oven tail is drawn by a high-pressure variable-frequency induced draft fan, a powder material can fly spirally in the airflow activation oven, feeding is started when the temperature is raised to 1100-1200 DEG C, dried saturated activated carbon in the standby bin is fed into the airflow activation oven by a screw conveyer and the fans to be activated, and the saturated activated carbon is rapidly boiled in the airflow activation oven to complete activation and pore forming; steam generated by a waste heat boiler is injected into the airflow activation oven for activation and pore forming; finally, a product enters a cooler from the activation oven to be cooled, subjected to cyclone separation, discharged and then is introduced into a finished product mixer, and remainders are introduced into the finished product mixer through a pulse bag dust collector. With adoption of the activated carbon regeneration equipment and process, product quality is improved substantially, the product yield is increased, energy conservation and emission reduction are realized in a production process, cleaner production is realized, and little environmental pollution is caused.

Description

technical field [0001] The invention relates to the field of production and manufacture of regenerated activated carbon, and more specifically relates to a rapid airflow activation furnace activated carbon regeneration equipment and a process thereof. Background technique [0002] Activated carbon is a very good adsorbent. It uses charcoal, various fruit shells and high-quality coal as raw materials, and uses physical and chemical methods to crush, sieve, activate catalysts, rinse, dry and screen raw materials. Manufactured through a series of processes. It has the dual characteristics of physical adsorption and chemical adsorption, and can selectively adsorb various substances in the gas phase and liquid phase to achieve the purposes of decolorization, purification, disinfection, deodorization, decontamination and purification. Activated carbon can be divided into primary activated carbon and regenerated activated carbon. Due to the advantages of developed large, medium, ...
