Novel phosphoric acid process active carbon production converter

Abstract

The invention discloses a novel phosphoric acid process active carbon production converter, which comprises a preheating section, a carbonization section and an activation section, wherein a preheating section converter, a carbonization section converter and a activation section converter are respectively provided with a transmission system, a connecting system is arranged at the material outlet end of the preheating section converter and the material inlet end of the carbonization section converter, a connecting system is arranged at the material outlet end of the carbonization section converter and the material inlet end of the activation section converter, a heat supply system is arranged at the material outlet end of the activation section converter, and the connecting systems are respectively and internally provided with a heat supply vent so as to ensure the hot gas supply in a preheating process and a carbonization process. According to the novel phosphoric acid process active carbon production converter, the content of phosphoric acid in tail gas is reduced, the acid consumption is reduced to a certain extent, the whole process is completed in a furnace body, and the production continuity is ensured.

Description

technical field [0001] The invention relates to wood powder activated carbon production equipment, in particular to a novel converter for phosphoric acid activated carbon production. Background technique [0002] The impregnation of phosphoric acid and wood chips in the production process of phosphoric acid activated carbon has a certain impact on the quality of the product and the entire production process, and the temperature also has an impact on the impregnation of phosphoric acid and wood chips. It is at room temperature, after being extruded and kneaded by a double auger, it enters the converter and directly starts carbon activation. This process makes the degree of impregnation of sawdust and phosphoric acid insufficient, resulting in the weakening of the catalytic effect of phosphoric acid, causing the sawdust to burn into ash at high temperature, and at the same time, the yield is reduced. At the same time, the temperature of the carbonization section at the end of ...

This process makes the degree of impregnation of sawdust and phosphoric acid insufficient, resulting in the weakening of the catalytic effect of phosphoric acid, causing the sawdust to burn into ash at high temperature, and at the same time, the yield is reduced. At the same time, the temperature of the carbonization section at the end of the furnace after the impregnated sawdust enters the furnace body is not suitable for control, resulting in energy consumption. increase
