[0002] Because harmful gases from factories and many chemical companies need to be treated before they can be discharged into the atmosphere, baking soda particles are usually used to neutralize and remove harmful gases, especially those containing acidic gases. Baking soda is cheap and can be used in large quantities.

[0003] At present, baking soda powder after chemical reaction of desulfurization is stored in ash bin through ash conveying pipeline. However, due to the high humidity in the ash bin, the baking soda used after the reaction in the ash bin is easily decomposed to form sodium carbonate. Sodium carbonate will clump due to deliquescence, causing blockage, affecting the ash discharge speed, and bringing great difficulties to production. Summary of the invention

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] In the treatment of harmful gases, after the treatment with baking soda, the baking soda residue is discharged into the accelerated desulfurization and dust removal ash bin. When the ash in the ash bin is treated, the damp baking soda agglomerates in the bin and cannot be discharged smoothly. Therefore, the present invention provides an ash discharge device for the accelerated desulfurization and dust removal ash bin to facilitate ash discharge.

[0026] The steam heating pipe 31 is coiled on the outer surface of the ash bin body 1. A first valve 32 is provided at the inlet and outlet of the steam heating pipe 31. The steam heating pipe 31 is used to heat and dry the ash in the ash bin body 1, so that the ash can fall off from the ash bin body 1 more easily. The cross section of the ash bin 21 is an inverted trapezoid. The steam heating pipe 31 is coiled on the outer surface of the ash bin body 1 for at least two turns.

[0027] At least two nitrogen inlet pipes 41 are arranged on one side of the ash bin body 1, and a nitrogen discharge pipe 42 is provided on the ash bin body 1 on the other side corresponding to the nitrogen inlet pipe 41. The nitrogen inlet pipe 41 and the nitrogen discharge pipe 42 are connected to the inner cavity of the ash bin body 1 and are used to purge the inner cavity of the ash bin body 1 to blow off the ash adsorbed on the inner wall of the ash bin; a second valve 43 is provided on the nitrogen inlet pipe 41 and the nitrogen discharge pipe 42; the at least two nitrogen inlet pipes 41 are evenly arranged on one side of the ash bin body 1.

[0033] The operator of the present invention can use a remote controller to control the control switch 61 to implement three types of warehouse clearing processes, or can directly control the control switch 61 on site;

[0034] When cleaning the ash in the ash bin body 1, if the ash bin is damp, the steam switch of the control switch 61 is turned on, and the controller 6 controls the first valve 32 to open, and hot steam is passed into the steam heating pipe 31 to heat the ash bin body 1, so that the ash bin body 1 is dry, and the ash containing baking soda is separated from the ash bin body 1;

[0035] During or after drying, turn on the nitrogen switch of the control switch 61 to purge the ash bin body 1, or turn on the rapper switch at the same time to speed up the ash discharge. When the ash unloading switch is turned on, the ash in the ash bin body 1 is discharged from the inner cavity of the bin.
