High-yield and high-efficiency activated carbon activation device and activation process

Abstract

The invention discloses a high-yield and high-efficiency activated carbon activation device and activation process. The activation device comprises a furnace body, a regenerative chamber and a steam boiler; a flue on the inner side of the furnace body is divided into an upper near flue, an upper far flue, a lower near flue and a lower far flue by cover plate bricks, wherein the upper near flue, the upper far flue, the lower near flue and the lower far flue are each provided with a second air distribution opening; the second air distribution opening comprises an upper air distribution port anda lower air distribution port; and air distribution control valves are arranged on the upper air distribution port and the lower air distribution port respectively. The activation process comprises the following steps: adding the carbonized material into a feeding tank, activating the carbonized material in the activation tank through the feeding preheating section, the supplementary carbonizationsection, the activation section and the discharge cooling section in sequence from top to bottom, and finally, outputting the cooled activated material through a discharge bin. The activated carbon activation device is optimally designed, so that the activation process breaks through the traditional temperature limit, the activated carbon activation rate is increased, the operation efficiency ofthe activation waste heat boiler is improved, and the balance between steam consumed by activation furnace production and steam produced by tail gas waste heat is realized.

Description

technical field [0001] The invention relates to the technical field of coal-based activated carbon production, in particular to a high-yield and high-efficiency activated carbon activation device and an activation process. Background technique [0002] Sleep activation furnace is a brick-structured saddle activation furnace imported from the former Soviet Union. It adopts the alternating activation method of water vapor and flue gas, and is suitable for the production of various granular activated carbons. The activation process conditions are stable, the product quality is uniform, and the adsorption performance is good, especially in the production of high-quality activated carbon. It has very unique advantages. [0003] The steam power required for traditional activated carbon production is realized by using coal-fired steam boilers or gas-fired steam boilers. As the use of power energy is limited and the price continues to rise, especially the continuous improvement of ...

Problems solved by technology

[0005] However, while improving the efficiency of the activation furnace by increasing the temperature, the high temperature will increase the burden on the activation furnace, and the local high temperature of the furnace core brick will easily lead to the occurrence of vicious accidents in the furnace body such as blockage of the product channel and burning of the furnace core brick.

And it is easy to cause the problem of increased charcoal loss rate
