Furnace body of activated carbon activation furnace

Abstract

The invention discloses a furnace body of an activated carbon activation furnace, and relates to the field of activated carbon production devices. The furnace body can improve the safety of the activated carbon production process to a certain degree, can stably run for a long time, and can greatly improve the quality and yield of produced activated carbon. The furnace body is internally provided with a combustion channel communicated with the interior of the furnace body. Air is introduced in the combustion chamber. The interior of the furnace body is divided into at least two material channels. The material channels are arranged in the length direction of the furnace body. Vapor is introduced in each material channel. The furnace body comprises an outer cylinder. At least two branch warehouse supporting pieces are arranged in the circumferential direction of the inner wall of the outer cylinder and form the combustion chamber. One material channel is formed among two adjacent branch warehouse supporting pieces, the inner wall of the outer cylinder and the outer wall of the combustion chamber. The furnace body is mainly used for producing activated carbon.

Description

technical field [0001] The invention relates to the field of activated carbon production equipment, in particular to a furnace body of an activated carbon activation furnace. Background technique [0002] At present, the production methods of activated carbon at home and abroad are mainly divided into two categories, namely: physical method and chemical method. The physical method is to first put the raw materials (high-quality coal, fruit shells, charcoal, etc.) in a closed furnace body for smoldering and carbonization, and then pass in an appropriate amount of water vapor to activate to obtain activated carbon. The chemical method is to impregnate raw materials (usually sawdust) with chemicals (phosphoric acid, zinc chloride, etc.), and then carbonize and activate them in an air-circulating furnace to obtain activated carbon. At present, many manufacturers use physical methods to produce activated carbon. [0003] At present, the equipment for producing activated carbon ...

AI Technical Summary

Problems solved by technology

[0004] However, the existing activation furnaces for the production of activated carbon by physical methods generally have certain technical defects: (1) The safety hazard is relatively large: due to the inconsistency of the carbonized material composition after heating, the change in the amount of gas produced will cause the instability of the gas pressure, the sudden change of the air pressure It will cause deflagration of high-temperature gas, causing safety hazards such as burning at the seal of the furnace body, especially for rotary activation furnaces, the sealing performance of the rotary joint is relatively poor, once burning occurs, it is easy to cause safety accidents

(2) The production capacity and quality of activated carbon are low: because the furnace body cannot be well sealed in the area, the combustible gas precipitated by the heating of the material is easy to burn directly in the area where the material is placed, resulting in a large increase in the amount of carbonized material or activated carbon ablation, reducing the The production capacity and quality of activated carbon increase the consumption of raw materials and energy; at the same time, the existing activation furnace has a limited feeding amount per unit time, and the production capacity of activated carbon cannot be further significantly improved, and the added raw materials are always piled up in the lower part of the activation furnace due to gravity. Difficult to fully contact with steam, resulting in poor activation effect and reduced quality of activated carbon
