Stir-fry-type activated charcoal stove

Abstract

The invention provides a stir-fry-type activated charcoal stove. A hearth is internally provided with a furnace bed formed by vertically stacking a plurality of fixed furnace sections. The center of the furnace bed is provided with a rotating mandrel. A combustion smoke and fire channel is arranged between the furnace bed and the inner wall of a heat preservation shell. Furnace sections comprise material sauting chambers and smoke and fire return channels to heat both the upper faces and the lower faces of the material sauting chambers. The rotating mandrel is provided with rotatable sauting tables stretching into the material sauting chambers of all the furnace sections. Outer material descending channels are arranged between the outer edges of the rotatable tables and the side walls of the material sauting chambers. The lower surfaces of the rotatable tables are connected with a plurality of movable sheets for poking materials towards inner material descending channels in a hinged mode. The lower surfaces of top covers of the material sauting chambers are connected with fixed sheets for poking material towards the outer material descending channels in a hinged mode. The material sauting chamber of each furnace section is provided with an activating agent input pipe and an output pipe for combustible gas generated by carbonized activated materials. The stir-fry-type activated charcoal stove simplifies and purifies the production process, greatly lowers energy consumption, increases the yield of products and improves the quality of the products.

Description

Technical field [0001] The invention relates to an activated carbon production equipment, in particular to a frying type activated carbon furnace. Background technique [0002] At present, in terms of activated carbon production technology, it is common to use chemical activation to pretreat raw materials. The most representative pretreatment of chemical activation methods are: zinc chloride method, phosphoric acid (salt) method, calcium chloride method and chemical activation method with alkali as activator (alkaline method). The chemical activation method is a method in which chemicals are added to the raw materials and then heated in an inert gas medium for carbonization and activation. However, the chemical activation method has three disadvantages: ① It is very corrosive to equipment; ② Pollution to the environment; ③ Chemical activator remains in the activated carbon, and its application is limited. [0003] The world-renowned activated carbon activation equipment includes...

AI Technical Summary

Problems solved by technology

However, the chemical activation method has three major disadvantages: ①It is very corrosive to the equipment; ②It pollutes the environment; ③There are chemical activators in the activated carbon, so the application is limited

If crushing and granulation is used, the cost of activated carbon will be increased, which is uneconomical
