Embodiment 1

[0059] Using domestic waste as raw material, the method steps for preparing activated carbon from domestic waste are as follows:

[0060] (1) Screen, magnetically separate and crush 10 tons of household waste to obtain organic matter with a particle size below 30mm;

[0061] (2) Send the broken domestic garbage into the pyrolysis furnace for pyrolysis, and the materials are evenly distributed on the distribution board, with a material layer thickness of 120mm; the temperature of the residual carbon obtained by pyrolysis is 500°C, and the temperature of the pyrolysis gas is 600°C. Residual charcoal is sent to the multi-stage furnace;

[0062] (3) The medium-high temperature pyrolysis gas produced by pyrolysis is sent to the buffer tank for storage and heat preservation, and the pyrolysis gas after heat preservation is sent to the burner for combustion. The burner adopts a regenerative burner;

[0063] (4) Send the flue gas burned by the burner into the purification separator, ...

Abstract

The invention discloses a system and a method for preparing activated carbon by aid of a pyrolyzing furnace and a multistage furnace. The system comprises a pretreatment device, the pyrolyzing furnace, the multistage furnace and a buffer tank, wherein a pyrolyzing raw material outlet of the pretreatment device is connected with a pyrolyzing raw material inlet of the pyrolyzing furnace, a carbon residue outlet of the pyrolyzing furnace is connected with a carbon residue inlet of the multistage furnace, a pyrolyzing gas outlet of the pyrolyzing furnace is connected with a gas inlet of the buffer tank, and a gas outlet of the buffer tank is connected with a fuel gas inlet of a burner. The method is a method for preparing activated carbon by the use of the system. By means of the system and the method for preparing the activated carbon, the problems that dust is heavy and pipelines are blocked in the material pyrolyzing process are solved; energy consumption of the system is low, and the self-sufficiency rate of energy is high; no toxic or harmful gas can be produced.

Description

technical field [0001] The invention belongs to the technical field of activated carbon preparation, and in particular relates to a system and method for preparing activated carbon by a pyrolysis furnace and a multi-stage furnace. Background technique [0002] Activated carbon is a type of microcrystalline carbon material made of carbon-containing materials with a black appearance, developed internal pore structure, large specific surface area, and strong adsorption capacity. There are a large number of micropores invisible to the naked eye in activated carbon materials. Activated carbon is mainly used to remove pollutants in water, decolorize, filter and purify liquids and gases, and is also used for air purification, waste gas recovery (such as the recovery of gas "benzene" in the chemical industry), recovery and refining of precious metals (such as the absorption of gold), and the volatile gases such as formaldehyde, benzene, ammonia, and toluene emitted in the indoor ai...
