Abstract

The invention discloses a making method of wastewater active charcoal through waste tyre in the processing method technical domain of environmental protective solid waste, which is characterized by the following: transmitting entire or broken waste tyre into pyrogenic stove; transmitting carbon waste in the charring activating furnace; sending non-condensed gas into combusting furnace; inducing high-hot CO2 and H2O flow into charring activating furnace to heat charring activating furnace; adopting incomplete combusting carbon black as new additional raw material; insulating the charring activating furnace from air; reducing to below 100 deg.c to obtain the product; alternating two stoves.

Description

technical field [0001] A method for preparing activated carbon for wastewater treatment by using waste tires relates to a method for treating waste tires, and belongs to the technical field of environmental protection solid waste treatment methods. Background technique [0002] Traditionally, the raw materials for the production of activated carbon are mainly carbon-containing natural plants and minerals such as coal, wood and nut shells, and the reserves of coal are limited. In addition, the state implements natural forest protection projects, which restricts wood harvesting and the source of raw materials is limited. . High-temperature pyrolysis of waste tires produces oil with high residual carbon content and sufficient supply. Waste tires have the potential to become a low-cost raw material for the manufacture of activated carbon. [0003] Water pollution is one of the main environmental problems facing my country at present. In my country, activated carbon technology i...
