Abstract

The invention belongs to the field of chemical engineering devices and relates to a carbonization and activation device for active coke production. The device comprises a material channel and flues at two sides of the material channel. The device also comprises a preheating section, a carbonization section, an activation section and a cooling section and the sections are orderly arranged from top to bottom along a vertical direction. The flues in the carbonization and activation sections are respectively provided with gas burners. The flue in the activation section is provided with an activator inlet. The device realizes combination of carbonization and activation, has less processes, uniform and continuous reaction processes, a fast activation rate, a high raw material utilization rate and high production power, greatly reduces power and energy consumption and has a low cost and a high product yield.

Description

technical field [0001] The invention belongs to the technical field of chemical devices, and in particular relates to a carbonization and activation device for active coke production. Background technique [0002] At present, the process of preparing carbon material adsorbents at home and abroad is produced separately by two steps of carbonization furnace and activation furnace. The raw materials produced are different, and the carbonization furnace and activation furnace equipment used will also be different, such as earth kiln, pit furnace, honeycomb furnace, mobile furnace, external heating rotary kiln, internal heating rotary kiln, etc. [0003] The external heating rotary carbonization furnace has the advantages of uniform temperature heating, simple operation, high product yield, and good product quality. However, due to complex structure, high cost, low thermal efficiency, and small output, it is only used in the production of high-quality adsorption materials. ; The...
