Movable miniaturized biomass continuous steam activation method and activation machine

Abstract

The invention discloses a movable miniaturized biomass continuous steam activation method and an activation machine. An activation reaction tube and an activation propulsion screw are adopted to complete movement of a carbon base in an activation combustion chamber, and by controlling the temperature in the activation combustion chamber, the carbon base is subjected to steam high-temperature activation reaction in a short distance to obtain the finished activated carbon, thereby implementing miniaturization of carbon base activation. The activation machine comprises a rack (1), an activation combustion chamber (2) is arranged on the rack (1), an activation reaction tube (5) is arranged in the activation combustion chamber (2), an activation propelling screw (6) is arranged in the activation reaction tube (5), and a heating area and a steam high-temperature activation area are sequentially arranged on the activation reaction tube (5) along the material propelling direction. The method has the characteristics that the production cost can be effectively reduced, the product quality is improved, the energy consumption is reduced, and the environmental protection performance is improved.

Description

technical field [0001] The invention relates to a carbon-based activation equipment, in particular to a movable miniaturized biomass continuous steam activation method and an activation machine. Background technique [0002] Biomass is mainly agricultural and forestry waste, such as straw, sawdust, bagasse, rice bran, etc. Direct combustion of biomass is a highly polluting fuel, which is only used in large stoves in rural areas and is not allowed to be used in cities; currently, the application of biomass It mainly involves new clean fuels and biomass activated carbon. Making activated carbon from biomass raw materials mainly includes two processes: making biomass raw materials into carbon base and activating the carbon base to obtain activated carbon. However, at present, the production of biomass activated carbon is still dominated by traditional processes and equipment. Since the activation furnace equipment that activates the carbon base occupies a large area, it also n...

Problems solved by technology

However, at present, the production of biomass activated carbon is still dominated by traditional processes and equipment. Since the activation furnace equipment that activates the carbon base occupies a large area, it also needs to be equipped with large-scale conveying lines, steam boilers, etc., equipment and land investment Larger, once installed, it is very troublesome to change the location; however, the existing two production processes of carbon-based and activation are carried out separately, and the transportation cost of carbon-based is also relatively high. Many factors are superimposed, resulting in the final Activated carbon is expensive to produce

Moreover, in the steam activation process, a large amount of carbon base needs to be activated, which makes it more difficult for the steam to fully contact with the carbon base, resulting in uneven activation.

Furthermore, the high-temperature steam used in the activation process needs to be obtained by using additional energy to heat the boiler, which consumes a lot of energy

At the same time, a large amount of polluting waste gas will be emitted during the combustion process, which will easily affect the environment

Therefore, the existing technology has the problems of large equipment volume, high production cost, unstable quality, high energy consumption and easy pollution to the environment
