Problems solved by technology

[0003] At present, the mainstream equipment for producing activated carbon is internal heat activation equipment, such as Sleep furnace and internal heat rotary furnace, but there are several problems in this kind of process and equipment: 1. Because of the internal heating, the insulation layer must be inside the equipment, resulting in The equipment structure is relatively complicated, and the cost is relatively high; 2. In the internal heating reaction, the main components generated by the reaction of carbonized material and water vapor at high temperature are hydrogen, carbon monoxide, a small amount of carbon dioxide and trace alkanes, which are activated in a specific position at the right time Air is introduced into the device, and the oxygen in the air and the flammable gas generated by the activation reaction undergo flameless combustion and release heat to maintain the continuous activation reaction. When the air is introduced, there will be a small amount of gas in the small space of the activation device. In contact with carbonized materials, an oxidation reaction occurs, which reduces the activation yield; 3. The structure in the furnace is complex, and the equipment requires frequent maintenance
[0004] At present, there are few external heat activation devices in the market. The main reason is that although the external heat activation device is relatively cheap in cost and easy to operate, it needs an additional heat source to maintain the activation temperature, which consumes a lot of energy and has high production costs.

Description

technical field [0001] The invention belongs to the technical field of activated carbon production, and specifically relates to an external heat rotary activated carbon high-efficiency production device and method, more specifically, an external heat rotary activated carbon high-efficiency and energy-saving production device. Background technique [0002] The principle of using carbonized material to produce activated carbon is that in the range of 700-1000 ° C, the high-temperature carbonized material and water vapor undergo a chemical reaction, and the surface void structure of the carbonized material itself increases and becomes larger, thereby achieving the activation effect. At present, there are two main ways to prepare activated carbon from the carbonized material in the existing activation furnace: one is the internal heating type, that is, the carbonized material is in the activation device, and the heating and temperature rise occurs in the device, and the carbonize...
