Problems solved by technology

The above-mentioned carbonization furnace recycles flammable and explosive high-temperature organic vapors produced during the high-temperature carbonization process, and burns them as fuel to provide the heat energy required for material carbonization. Excessive air, and the exhausted oxygen in the excess air reacts violently with these flammable and explosive high-temperature organic vapors, and it is very easy to explode in a small space in the furnace
At the same time, the reaction of oxygen and carbon will generate flammable, explosive, and toxic gas CO, and it is difficult to have a reliable seal for the two drums under high temperature conditions. These flammable, explosive, and toxic organic vapors and CO will overflow and cause safety accidents. At the same time, it discharges toxic and harmful pollutants to the environment, and its dust overflow will also pollute the environment.
After the organic vapor is burned by the combustion device, on the one hand, the high value-added part of the organic vapor that can be separated is not used, and on the other hand, the exhaust gas after combustion is not purified, that is, the discharge will pollute the environment

Embodiment 1

[0022] Such as figure 1 , figure 2 As shown, a kind of activated carbon carbonization process device system, this system is a spiral stepped fin type carbonization tower and its supporting equipment, the carbonization tower includes a tower body 7, a storage tank 2 located at the top of the tower body 7 and a feed Port 1, the high-temperature organic vapor outlet provided at the upper end of the tower body 7 4, the blanking tray assembly 9 arranged at the lower end of the tower body 7, the supporting column 8 arranged at the lower part of the tower body 7, and the base arranged at the bottom end of the tower body 7 10.

[0023] The fins 5 are arranged in spiral steps along the axis of the central column 3 , and the fins 5 and the central column 3 are hollow structures. One end of the fins 5 is connected to the center column 3 , and the other end is connected to the ventilation pipe 6 . The two ends of the ventilation pipe 6 are connected with the corresponding two fins 5 ....

Embodiment 2

[0028]An activated carbon carbonization process: the material enters the storage tank 2 from the elevator 21 through the feed port 1 of the spiral stepped fin carbonization tower, falls into the fin 5 under the action of gravity, and the blanking tray assembly 9 drives the central column 3 Rotate around the central axis of the tower body 7, thereby driving the fins 5 to rotate. Since the fins 5 are arranged in a spiral step along the axis of the central column 3, the material moves downward spirally around the central axis of the tower body 7 under the action of gravity to the blanking The disc assembly 9, in this process, the fins 5, the ventilation pipe 6, and the central column 3 heat the material in the air-isolated air-tight space of the tower body 7, thereby completing the carbonization process. The high-temperature organic vapor generated during the material carbonization process is pulled by the vacuum pump 15 through the gap between the fins 5, enters the cyclone separ...

Abstract

The invention relates to the field of environmental protection, specifically to a carbonization process unit system and a carbonization method for active carbon. The carbonization process unit system is characterized by comprising a spiral stepped fin type carbonization tower and matched devices thereof. Since high-temperature flue gas and a material do not react due to direct contact, the danger of explosion is eliminated, and the yield of active carbon is improved. Since the operating principles of a tower reactor are employed, carbonization process is highly efficiently finished, and energy consumption is reduced. Through adjusting the rotating speed of a discharging disc, the carbonization production process is controllable, continuous and highly efficient. As raw materials and a product always undergo reaction in an enclosed apparatus, leakage of high-temperature organic steam and dust can be effectively prevented, and environmental pollution is avoided. Meanwhile, the carbonization process unit system effectively separates a high-added-value organic liquid part of the high-temperature organic steam, and a normal-temperature non-condensable part of the high-temperature organic steam is used as a fuel to provide heat energy needed by the high-temperature organic steam, thereby saving resources.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to an activated carbon carbonization process device system and a method thereof. Background technique [0002] The history of human use of activated carbon is not long. From the large-scale use of activated carbon in gas masks in World War I, it has gradually played an irreplaceable role in the field of environmental protection and governance. The production of activated carbon is usually divided into two relatively independent processes of carbonization and activation. As we all know, the process of material carbonization at high temperature will produce a gaseous product with a wide molecular weight distribution, which is usually called high-temperature organic vapor. How to reliably recover these flammable and explosive high-temperature organic vapors to ensure safe production and avoid environmental pollution; at the same time, to increase the carbonization yield of acti...
