A combined physical and chemical activation device for biocoke

Abstract

A combined physical and chemical activation device for biocoke, comprising an activation box, gas storage tanks are fixedly installed on both sides of the top surface of the activation box, and the inside of the bottom of the gas storage tank is respectively fixedly connected to one end of a first air pipe, and the other end of the first air pipe is connected to Pass through the top surface of the activation box, the inner wall of the activation box is fixedly connected to the outer circumference of the spiral tube, and several air holes are evenly opened on the top of the inner wall of the spiral tube. One end of the second air pipe is fixedly connected, and the other end of the second air pipe passes through the activation box. An annular groove is provided on the lower part of the inner wall of the activation box, and a circle of chute is provided on the bottom surface of the annular groove. The present invention can heat the activation box by arranging the spiral pipe in the activation box, reduce the heat loss in the activation box, and facilitate the activation process to be carried out under a suitable temperature condition. Temperature, can save energy, more energy-saving and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of biological coke, in particular to a physical and chemical combined activation device for biological coke. Background technique [0002] Biomass pyrolysis polygeneration technology can simultaneously produce high calorific value biogas, biocoke, wood tar and wood acetic acid, which has significant economic benefits and has greatly promoted the development of the biomass energy industry. Biomass coke, one of the three major products of biomass pyrolysis polygeneration, is a cheap adsorbent that can be used in water treatment, contaminated soil remediation, air purification, CO2 capture, flue gas desulfurization and denitrification, etc. a lot of uses. Improving the adsorption performance of biocoke and increasing its added value is an important driving force to promote the large-scale industrialization of biomass pyrolysis polygeneration technology. [0003] The surface properties of bio-coke are an impor...

AI Technical Summary

Problems solved by technology

At present, the surface properties of bio-coke have been improved by means of physical and chemical combination, but the existing combined activation device only activates bio-coke, and there are great deficiencies in the discharge of mixed gas after activation and the cooling of bio-coke after activation.
