Detailed Description
For better understanding of the present invention, the following examples are further illustrative of the present invention, but the present invention is not limited to the following examples.
As shown in fig. 1 and 2, the automatic dust removing device for tail gas of powdered activated carbon regeneration equipment provided by the present invention comprises a hollow spiral twisted blade dust removing mechanism 1, a tail gas discharge pipe 2 of a regeneration furnace, and a water-cooled tail gas collecting tower 3;
inside regenerator tail gas discharge pipe 2 stretched 3 induction ports of water-cooling tail gas collection tower, 3 insides of tail gas collection tower keep the negative pressure, ensure that the dust can not waft and fall to the system outside. The driving end of the hollow spiral blade ash removal mechanism 1 is fixed on the water-cooling tail gas collecting tower 2, and the other end of the hollow spiral blade ash removal mechanism penetrates through the water-cooling tail gas collecting tower 3 and is placed in the tail gas discharge pipe 2 of the regenerating furnace in a floating mode.
The hollow spiral twisting blade ash removing mechanism comprises a gear hollow spiral twisting blade 11, a universal coupling 12 and a gear reduction motor 13; the hollow spiral hinge 11 is connected with a gear reduction motor 13 through a universal coupling 12 and rotates under the driving of the gear reduction motor 13. The dust deposited in the tail gas discharge pipe 2 of the regeneration furnace horizontally moves under the pushing of the hollow spiral twisting blade 11, and the dust deposited in the tail gas discharge pipe 2 of the regeneration furnace is pushed back into the material pipe or is drawn out of the tail gas discharge pipe 2 of the regeneration furnace by adjusting the rotating direction of the gear reduction motor 13.
The hollow spiral twisted blade 11 is made of heat-resistant stainless steel so as to adapt to the high-temperature environment in the tail gas discharge pipe 2 of the regeneration furnace. Meanwhile, in order to avoid the hollow spiral twisting blade 11 from being blocked in the tail gas discharge pipe 2 of the regeneration furnace due to the fact that the hollow spiral twisting blade 11 is heated and expanded in the tail gas discharge pipe 2 of the regeneration furnace, the diameter of the hollow spiral twisting blade 11 is slightly smaller than the inner diameter of the tail gas discharge pipe 2 of the regeneration furnace, and therefore safety and reliability in the operation process of equipment are guaranteed.
When the water-cooled tail gas collecting tower 3 is heated during operation, thermal expansion can occur to cause the installation position of the gear reduction motor 13 to change in the height direction. In order to adapt to the working condition, a double-joint universal coupling 12 is adopted for connection between the driven gear reduction motor 13 and the hollow helical twisting blade 11 so as to eliminate the adverse effect caused by thermal expansion.
The during operation of powder active carbon regenerator is heated, can take place thermal energy and arouse that regenerator tail gas discharge pipe 2 takes place the displacement at relative hollow spiral twisted blade 11 emergence axial direction, for adapting to this kind of operating mode, with the floating arrangement of hollow spiral twisted blade 11 in regenerator tail gas discharge pipe 2 to eliminate the influence that regenerator tail gas discharge pipe 2 displacement brought.
The water-cooled tail gas collecting tower 3 comprises a flue gas channel 31 and an interlayer channel wall 32, and cooling water is introduced into the interlayer channel wall 32. The cooling water in the interlayer channel wall 32 moves from bottom to top, and cools the air temperature in the flue gas channel 31 and simultaneously cools the hollow spiral blade ash removal mechanism 1, so that the gear reduction motor 13 is prevented from being over-heated.
The utility model discloses at the regenerator during operation, it is rotatory to last to keep the low-speed, in time push back the interior or draw out regenerator tail gas discharge pipe 2 with the dust of deposit in regenerator tail gas discharge pipe 2 outside, it can be smooth and easy discharge among regenerator tail gas discharge pipe 2 to keep the interior tail gas of regenerator, thereby effectively avoid powdered activated carbon to pile up at regenerator tail gas discharge pipe 2 interior dust, block up the flue, arouse the exhaust pipe surge, spout accidents such as ash, effectively avoid uncertainty and the potential safety hazard that artifical deashing brought simultaneously.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood that the invention is not limited thereto, and that various modifications and changes can be made by those skilled in the art without departing from the principles of the invention.
