Embodiment Construction
[0022] Below in conjunction with accompanying drawing, the present invention will be further explained:
[0023] see figure 1 , the tower body consists of heating zone F, reaction zone G, sub-cooling zone H and cooling zone I from bottom to top. Cooling water coils are arranged in the reaction zone G, sub-cooling zone H and cooling zone I, and the tower A cooling water jacket 11 is provided on the wall, and an oxidizing gas distributor 13 and a hot water jacket 10 on the tower wall are provided in the heating zone.
[0024] The heating zone F is provided with an oxidizing gas inlet 3 connected to an oxidizing gas gas distributor 13, and the lower section of the reaction zone G has an upper sulfide feed layer 5.1 and a lower sulfide feed layer 5.2 with different vertical heights. The vertical distance between the lower sulfide feed layer 5.2 and the top surface of the heating zone F is 150mm-300mm, and the vertical height difference between the upper sulfide feed layer 5.1 and...
