Technical Field
[0001] The invention belongs to the technical field of activation furnaces and relates to a heat preservation device for a multi-tube activation furnace. Background Art
[0002] An activation furnace is a device specially used to convert wood or other cellulose raw materials into activated carbon. Currently, most activation furnaces are equipped with multiple activation tubes to improve the production efficiency of the activation furnace. The physical activation method of activated carbon is that the raw materials are in contact with activation gases such as water vapor or CO2 under high temperature conditions to perform an activation reaction. Due to the large temperature difference between the inside of the activation tube and the outside world, the heat in the activation tube will be transmitted to the outside world, causing a large loss of heat energy. In addition, the existing activation tubes are not well insulated, making it difficult to maintain a stable temperature inside the activation tube. More energy is needed to heat or maintain the temperature, thereby increasing production costs. Due to insufficient insulation, the temperature inside the activation tube fluctuates greatly, affecting the stability and efficiency of the activation reaction, which may lead to a decrease in the quality of the activated carbon.

The high temperature environment in the insulation cavity can further reduce the temperature difference between the insulation cavity and the activation tube, and can further reduce the heat in the activation tube from being transmitted to the insulation cavity, thereby further reducing heat loss and playing a better insulation role, so that the temperature in the activation tube is maintained stable to ensure that the raw materials are heated evenly, thereby better saving energy costs and reducing operating costs. When the raw materials are in contact with high-temperature water vapor for activation reaction, the activation tube rotation drive component drives each activation tube to rotate continuously, and the raw materials are in uniform and sufficient contact with the high-temperature water vapor during the rotation process, avoiding the problem of local over-activation or insufficient activation, and ensuring that the raw materials are heated evenly, improving the activation efficiency, and preventing the raw materials from being in a static state for a long time, causing agglomeration and agglomeration.

When the rotating positioning seat 14 rotates following the activation tube 3, the rotating bearing 16 between the positioning groove 15 and the high-temperature steam pipe 6 plays a role in rotatingly connecting the rotating positioning seat 14 and the high-temperature steam pipe 6, so that the high-temperature steam pipe 6 always remains in a stationary state and can reduce the friction and wear between the rotating positioning seat 14 and the high-temperature steam pipe 6 when the rotating positioning seat 14 rotates. The sealing covers 17 at both ends of the rotating positioning seat 14 play a sealing and protective role to prevent raw materials from entering the positioning groove 15.
[0057] The working principle of the present invention is as follows: the heat generated by the combustion of the fuel in the combustion chamber 45 enters the heating chamber 44 of the heating chamber 42 through the heat transfer pipe 46 to heat the high-pressure boiler 43, and the high-temperature steam generated by the heating of the high-pressure boiler 43 enters each high-temperature steam pipe 6 and each heat transfer pipe 19 through the steam main pipe 48 from the air inlet end of each high-temperature steam pipe 6;
[0058] The high-temperature water vapor in the high-temperature steam pipe 6 enters the activation tube 3 through the steam hole 12, so that the temperature in the activation tube 3 is quickly raised to a high-temperature environment. The raw material enters the activation tube 3 through the raw material inlet 4 of each activation tube 3 through the feeder. The rotation driver 33 operates to synchronously drive each activation tube 3 to rotate. The raw material reacts with the water vapor under the high-temperature environment to form activated carbon. Under the action of gravity, the activated carbon falls into the closed insulation chamber 28 from the raw material outlet 5 along the inclined activation tube 3 and is discharged through the discharge port 29.
[0059] The high-temperature water vapor in the heat transfer pipe 19 transfers heat to the insulation chamber 9 through the heat transfer pipe 19, causing the temperature in the insulation chamber 9 to rise to a high temperature and keeping the temperature in the insulation chamber 9 stable. The high-temperature environment in the insulation chamber 9 can further reduce the temperature difference between the insulation chamber 9 and the activation tube 3, and can further reduce the heat in the activation tube 3 from being transmitted to the insulation chamber 9, thereby further reducing heat loss and achieving a better insulation effect, so that the temperature in the activation tube 3 is maintained stable to ensure that the raw materials are heated evenly.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
