Abstract

The invention relates to a method for producing active carbon in a fluidization way, and relates to the production process of the active carbon and solves the technical problems that the existing carbon production process is high in energy consumption, the unit equipment yield is low, the investment is high and the production cost is high. The method comprises the following steps: heating a multichannel carbonization oven and an overheated steam activating oven; enabling coal particles to enter the multichannel carbonization oven, and drying and carbonizing the coal particles; entering a carbonized material into the overheated steam activating oven by virtue of the multichannel carbonization oven, and activating the carbonized material; entering the finished product active carbon into a gravity cooling machine by virtue of a discharging passage of the overheated steam activating furnace, and cooling the active carbon; entering high-temperature smoke produced by the overheated steam activating oven with granule active carbon into a gas-solid separator, and cooling the granule active carbon in a cooling heat exchanging water tank. The method has advantages of small energy consumption, little pollution, high unit equipment yield, low investment, low production cost and automatic control.

Description

technical field [0001] The invention relates to a production process of activated carbon, in particular to a method for producing activated carbon by fluidization. Background technique [0002] Activated carbon is a very versatile adsorbent, catalyst and catalyst support. It has a wide range of uses in food, sugar, medicine, chemical industry, environmental protection, national defense, agriculture, fuel gas storage, gas separation, catalytic reaction and many other fields. [0003] China's activated carbon industry has gone through more than 60 years of development since the 1950s. In this process, the main processes and equipment used are all from the former Soviet Union, that is, rotary furnace carbonization and Sleep furnace activation. At present, the process and equipment account for more than 90% of the total domestic production capacity. Although some improvements have been made, there is still no substantial change. After entering 2000, under the background of ex...
