[0002] Carbon black, also known as lampblack, is a kind of amorphous carbon. It is a light, loose and extremely fine black powder with a very large surface area. It is a product obtained by incomplete combustion or thermal decomposition of carbon-containing materials (coal, natural gas, heavy oil, fuel oil, etc.) under insufficient air conditions.

[0027] Most air supply devices supply air to one side of the main bag filter and heat the other side of the main bag filter. This will cause problems such as uneven air distribution and inaccurate airflow control in the air supply device, affecting the efficiency and effect of exhaust gas treatment, increasing the production time of carbon black powder, and increasing the production cost, causing economic losses, thereby reducing the practicability of the air supply device.

[0028] See also Figure 1-Figure 4 The embodiment of the utility model shown in the figure comprises a carbon black storage box 10 and a cover plate 11, a controller 12 is arranged on one side of the carbon black storage box 10, and a main bag filter 13 is arranged on the upper surface of the carbon black storage box 10; an air supply assembly 20 is arranged below the carbon black storage box 10, and the end of the air supply assembly 20 extends to the interior of the main bag filter 13, an adjusting assembly 30 for adjusting the wind speed and direction is arranged inside the air supply assembly 20 near one end of the main bag filter 13, and a heating assembly 40 for heating the wind is arranged inside the air supply assembly 20.

[0029] First, the specific structure of the air supply assembly 20 is disclosed. The air supply assembly 20 at least includes a centrifugal fan 21. The centrifugal fan 21 is located below the carbon black storage box 10. The air outlet of the centrifugal fan 21 is provided with an air distribution plate 22. The four sides of the air distribution plate 22 are provided with air supply connecting pipes 23. The other end of the air supply connecting pipe 23 is inserted into the interior of the main bag filter 13.

[0030] The improvement lies in that the air supply port of the centrifugal fan 21 is divided into four by an air distribution plate 22, and the air flows to the interior of the main bag filter 13 through four air supply connecting pipes 23, so that the air supply to different areas inside the carbon black reactor tail gas furnace is uniform, which not only reduces the cost of air supply, but also improves the uniformity of air supply, increases the working efficiency of the air supply device, and thus improves the practicability of the air supply device.

[0031] Secondly, the specific structure of the adjustment component 30 is disclosed. The adjustment component 30 at least includes a rotating shaft 31. The rotating shaft 31 is arranged inside the air supply connecting pipe 23 near one end of the main bag filter 13. The rotating shaft 31 is coaxially connected with an adjustment plate 32. One end of the rotating shaft 31 extends to the outside of the air supply connecting pipe 23 and is provided with a rotary valve 33.

[0032] The improvement lies in that: by rotating the rotary valve 33 to rotate the shaft 31 and adjusting the angle of the adjustment plate 32, it is beneficial to more accurately control the direction and intensity of the wind flow, and also realize accurate control of the wind flow distribution inside the tail gas furnace of the carbon black reactor, further improving the tail gas treatment effect, thereby improving the practicability of the air supply device.

[0033] The specific structure of the heating assembly 40 is disclosed again. The heating assembly 40 includes at least a plurality of annular heating tubes 41 . The air supply connecting tube 23 is provided with a plurality of annular heating tubes 41 , and the plurality of annular heating tubes 41 are connected in series through four connecting heat pipes 42 .

[0034] The improvement lies in: connecting multiple annular heating tubes 41 and four connecting heat pipes 42 to power and make them work, heating the air inside the air supply connecting tube 23, so that the heat can be transferred evenly and quickly, and through the design of the annular heating tube 41, it is evenly distributed inside the air supply connecting tube 23, thereby improving the heat conduction efficiency and shortening the reaction time. At the same time, the annular heating tube 41 adopts an intelligent temperature control system, which can accurately control the heating temperature, ensure the stability and safety of the reaction process, and improve the working efficiency of the air supply device.

[0035] Considering that when the heating component 40 heats the air inside the air supply connecting pipe 23, the air supply connecting pipe 23 will inevitably be damaged by the heat of the heating component 40, thereby reducing the service life of the air supply connecting pipe 23. Therefore, an insulating layer 24 is provided on the inner wall of the air supply connecting pipe 23.

[0036] The improvement lies in that: by providing a heat insulation layer 24, the temperature of the heating component 40 is separated from the inner wall of the air supply connecting pipe 23, preventing the heating component 40 from scalding the air supply connecting pipe 23, thereby increasing the service life of the air supply device, and also improving the stability and safety of the use of the air supply device, avoiding economic losses.

[0037] In summary, the working principle of the present scheme is as follows: first, the centrifugal fan 21 is powered on to make it work, and the air supply port of the centrifugal fan 21 is divided into four through the air distribution plate 22 connected to the air outlet of the centrifugal fan 21, and the air flows to the interior of the main bag filter 13 through four air supply connecting pipes 23. At the same time, multiple annular heating pipes 41 and four connecting heat pipes 42 are powered on to make them work, and the air inside the air supply connecting pipe 23 is heated. The rotating shaft 31 is rotated by rotating the rotary valve 33, and the angle of the adjusting plate 32 is adjusted to adjust the direction of the air outlet of the air supply connecting pipe 23 to the specified position, thereby completing the air supply work of the air supply device.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
