Embodiment 1

[0063] Taking biomass as raw material, the method for preparing activated carbon by using biomass (luzhu) to prepare activated carbon system is as follows:

[0064] 10 tons of reed bamboo are crushed to obtain crushed material with a particle size below 30mm;

[0065] Send the broken reed bamboo into the pyrolysis furnace for pyrolysis, and the material is uniformly distributed on the distribution board, and the thickness of the material layer is 150mm. The pyrolysis furnace is equipped with a burner to obtain residual carbon and pyrolysis oil gas, and the generated pyrolysis residual carbon is sent to the fluidized bed;

[0066] The pyrolysis oil and gas produced by pyrolysis are sent to the oil and gas separator for separation, and the oil and gas separator can obtain clean pyrolysis gas and pyrolysis oil and water;

[0067] Send the separated pyrolysis gas into the burner for combustion. The burner adopts a regenerative burner, which can increase the temperature of the nor...

Abstract

The invention relates to a system and a method for preparing active carbon by biomass. The system comprises a pyrolyzing furnace, a combustor, a steam boiler and a fluidized bed, wherein the pyrolyzing furnace is used for pyrolyzing raw material biomass to generate pyrolyzed oil gas and carbon residue; the combustor is used for heating the raw material biomass to pyrolyze the raw material biomass; the steam boiler is used for heating water to obtain steam; and the fluidized bed is used for activating the carbon residue to generate active carbon. According to the system and the method, the existing fluidized bed does not need to be transformed, heat loss is reduced, energy consumption is reduced, the productivity of the pyrolyzing furnace is improved, and reduction, harmless treatment and resource utilization of the materials is realized.

Description

technical field [0001] The invention belongs to the technical field of activated carbon produced by pyrolysis and gasification technology. Specifically, the invention relates to a system and method for preparing activated carbon, especially a method suitable for preparing activated carbon by pyrolysis and gasification using biomass as raw material. systems and methods. Background technique [0002] Biomass broadly refers to all plants, microorganisms, animals that feed on plants and microorganisms, and their wastes. Representative biomass is crops, crop waste, wood, wood waste and animal manure. In a narrow sense, it refers to lignocellulose (referred to as lignin) such as straw and trees other than grain and fruit in the process of agricultural and forestry production, leftovers from agricultural product processing, agricultural and forestry waste, and livestock manure and waste in the process of animal husbandry. . [0003] my country is very rich in biomass resources. ...
