Problems solved by technology

This process uses tail gas, which is not suitable for integrated production of activated carbon. Other components of the activated tail gas are still emptied, wasting resources and polluting the environment.
In addition, the process still requires boilers to provide steam, and its own production capacity cannot be used reasonably and effectively

Embodiment Construction

[0033] The specific implementation manners of the present invention will be further described below.

[0034] Implement a kind of coal-based activated carbon stove and prepare activated carbon method, the preparation method of described activated carbon is to carry out according to the following steps:

[0035] First, crush and mix 100g of lignite and 600g of weak caking coal, then extrude it under the pressure of 130Mpa, then crush the molding material to 3mm, and put it into the drying room of the raw material feeding room through the feeding equipment for drying. The temperature of the drying room is determined by the reaction Part of the hot gas generated by the combustion of natural gas in the furnace is provided, and the temperature of the drying room is controlled at 100°C for 60 minutes of drying.

[0036] Then the dry material enters the reaction unit for carbonization and activation under the action of gravity;

[0037] Then set the reaction temperature, reaction ti...

Abstract

The invention discloses a method for preparing activated charcoal by utilizing a coal-made activated charcoal furnace. The method comprises the following steps: briquetting a mixture of brown coal andweakly caking coal, crushing and drying; then supplying heat through electric heating and natural gas combustion to carry out carbonization under a nitrogen gas atmosphere; after carbonization reaction, introducing natural gas and oxygen gas according to the ratio from a natural gas inlet and an oxygen gas inlet; after the oxygen gas passes through an ion generator, mixing the oxygen gas and natural gas in a mixer; after conveying the mixed gas into a combustion chamber and combusting, generating water steam and carbon dioxide; after mixing the generated water steam and carbon dioxide with the introduced nitrogen gas, enabling mixed gas to enter a gas distribution chamber through a gas heat supply chamber; then enabling the gas to enter a reaction unit to be subjected to activation reaction with raw materials; finally, cooling a reaction product under the nitrogen gas atmosphere to obtain the activated charcoal. According to the method disclosed by the invention, carbonization and activation of coal-made activated charcoal is realized; pyrolyzed coal gas, the water steam and the carbon dioxide, which are generated in a carbonization process, are circularly utilized and the qualityof the produced activated charcoal is relatively high.

Description

technical field [0001] The invention relates to a method for producing activated carbon in a coal activated carbon furnace and a furnace for preparing activated carbon, in particular to a method and equipment for integrated production of activated carbon by using natural gas combustion, carbonization and activation. technical background [0002] Activated carbon is a carbonaceous adsorption functional material composed of microcrystalline carbon and amorphous carbon arranged in graphite-like crystallites. It has stable properties, excellent adsorption performance, acid and alkali resistance, heat resistance, and is insoluble in water or organic solvents. , It is widely used in the fields of catalyst carrier, medicine, industrial "three wastes treatment", battery, air purification and high energy density material storage. However, due to the advantages of low preparation cost, easy regeneration, and wear resistance, the market demand for coal-based activated carbon is increas...
