Description

Technical Field

[0002] Due to the special porous structure of activated carbon, it has a good removal effect on both organic sulfur and inorganic sulfur in flue gas. Activated carbon can also be used as a catalyst to decompose nitrogen oxides into nitrogen and water under the action of ammonia. Therefore, activated carbon has been widely used in the field of desulfurization and denitrification.

[0003] In the Chinese patent with the announcement number CN 215843013 U, an activated carbon regeneration tower of a desulfurization and denitrification system is disclosed, comprising a tower body, wherein the upper and lower ends of the tower body are respectively a feed cone and a discharge cone, a heating section is provided in the middle of the tower body, a heat exchange tube is provided in the heating section, a desorption gas outlet communicating with the inside of the heat exchange tube is provided on the tower body, the heating section has at least two sections, each heating section is arranged from top to bottom, each heating section comprises an upper tube sheet and a lower tube sheet both of which are sealed and connected to the inner wall of the tower body, the heat exchange tube is installed between the upper tube sheet and the lower tube sheet, the inside of the heat exchange tube is communicated with the space above the upper tube sheet and the space below the lower tube sheet, the middle transition section is located between the lower tube sheet of the previous heating section and the upper tube sheet of the next heating section, an air chamber is provided outside the tower body for communicating the spaces outside the heating tubes of the two upper and lower adjacent heating sections, the upper tube sheet of the uppermost heating section is located below the feed cone, the lower tube sheet of the lowermost heating section is an exhaust section, the exhaust section is located above the discharge cone, and the desorption gas outlet is opened on the side wall of the exhaust section.

[0004] The inventors found that at the discharge port of the activated carbon regeneration tower in the prior art, the activated carbon at the center and the activated carbon at the periphery fall at different speeds (the activated carbon at the periphery contacts the inner wall of the regeneration tower, resulting in a side wall effect, which affects the speed), resulting in different residence times of the activated carbon in the regeneration tower, affecting the regeneration effect of the activated carbon. Utility Model Content

[0005] The utility model aims to solve the problems existing in the prior art and proposes a regeneration tower with an activated carbon uniform distribution structure.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A regeneration tower with an activated carbon uniform distribution structure comprises a regeneration tower body, wherein a feed hopper and a conical bottom are respectively arranged at both ends of the regeneration tower body, an activated carbon speed uniform distribution structure is arranged above the inside of the conical bottom, the activated carbon speed uniform distribution structure is conical, and the activated carbon speed uniform distribution structure is connected to the inner wall of the conical bottom through a connecting piece.

[0008] Preferably, the connecting member is in the shape of a round rod, one end of which is connected to the inner wall of the cone bottom, and the other end is installed on the side of the activated carbon velocity uniform distribution structure.

[0009] Preferably, the activated carbon velocity uniform distribution structure is concentric with the cone bottom.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model has a cone-shaped activated carbon speed uniform distribution structure. When the activated carbon falls, the activated carbon located in the middle portion is slowed down due to the obstruction of the tip portion of the activated carbon speed uniform distribution structure during use, so that the falling speed of the activated carbon in the middle portion is kept close to that of the activated carbon located in the peripheral portion, thereby avoiding the situation in which the activated carbon at the periphery contacts with the inner wall of the regeneration tower and its speed is affected, resulting in different residence times of the activated carbon in the regeneration tower, thus affecting the regeneration effect of the activated carbon.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] Reference Figure 1-Figure 2A regeneration tower with an activated carbon uniform distribution structure comprises a regeneration tower body 1, wherein a feed hopper 2 and a cone bottom 3 are respectively arranged at both ends of the regeneration tower body 1, and the cone bottom 3 is used for discharging materials. A preheating section, a heating section and a cooling section are arranged in sequence from top to bottom inside the regeneration tower 1, and the cone bottom 3 is located below the cooling section. An activated carbon speed uniform distribution structure 4 is arranged above the inside of the cone bottom 3, and the activated carbon speed uniform distribution structure 4 is located between the cone bottom 3 and the cooling section. The activated carbon speed uniform distribution structure 4 is conical, and the activated carbon speed uniform distribution structure 4 is connected to the inner wall of the cone bottom 3 through a connecting member 5.

[0018] When the device is in use, when the activated carbon falls, the activated carbon located in the middle part is hindered by the tip part of the activated carbon speed uniform distribution structure 4, and the falling speed is slowed down, so that the falling speed of the activated carbon in the middle part is kept close to that of the activated carbon located in the peripheral part, thereby avoiding the situation that the speed of the peripheral activated carbon is affected by the contact with the inner wall of the regeneration tower, resulting in different residence time of the activated carbon in the regeneration tower, which affects the regeneration effect of the activated carbon.

[0019] In this embodiment, the connecting member 5 is in the shape of a round rod, one end of which is connected to the inner wall of the cone bottom 3, and the other end is installed on the side of the activated carbon velocity uniform distribution structure 4. The connecting member 5 allows the activated carbon velocity uniform distribution structure 4 to be floated above the cone bottom 3, and the round rod design prevents the activated carbon from remaining on the connecting member 5 when it falls.

[0020] In this embodiment, the activated carbon velocity uniform distribution structure 4 is concentric with the cone bottom 3, so that the tip of the activated carbon velocity uniform distribution structure 4 can be aligned with the center of the falling activated carbon.

[0021] In this embodiment, embedded plates are installed at both ends of the connecting member 5, and the two embedded plates are movably embedded in the side wall of the activated carbon velocity uniform distribution structure 4 and the inner wall of the cone bottom 3, and the two embedded plates are detachably connected to the side wall of the activated carbon velocity uniform distribution structure 4 and the inner wall of the cone bottom 3 by bolts. The design of the embedded plates facilitates the connection between the connecting member 5 and the activated carbon velocity uniform distribution structure 4 and the cone bottom 3.

[0022] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
