Example Embodiment

[0012] Depend on figure 1 It can be seen that an aeration device for oxidative desulfurization waste liquid includes an aeration oxidation tank, an oxidation fan, and an aeration pipeline. The aeration oxidation tank is a fixed pool (not shown in the figure), and the oxidation fan includes an upper oxidation fan 1 and a lower oxidation fan. Fan 2, the upper oxidation fan corresponds to the aeration pipe 3 on the upper layer, the outlet pipe is designed as an aeration pipe with a small diameter, which is arranged in the upper layer of the aeration oxidation tank, and the lower oxidation fan corresponds to the aeration pipe 4 on the lower layer, and the outlet pipe is in the tank. The bottom part is designed as an aeration pipe with a slightly larger aperture, which is arranged in the lower layer of the aeration oxidation tank. The outlet pipes of the two oxidation fans are connected. Switching of the gas system.

Abstract

The invention discloses an aerating device for oxidizing desulfurated waste liquid, which comprises an aerating oxidation pond, an oxidation fan and aerating pipelines and is characterized in that the aerating fan is provided with an upper oxidation fan and a lower oxidation fan; the upper oxidation fan corresponds to the upper-layer aerating pipeline, and the outlet pipeline of the upper oxidation fan is designed to be the aerating pipeline with smaller aperture and is arranged on the higher layer of the aerating oxidation pond; the lower oxidation fan corresponds to the lower-layer aerating pipeline, the under-pond part of the outlet pipeline of the lower oxidation fan is designed to be the aerating pipeline with bigger aperture, and the outlet pipeline of the lower oxidation fan is arranged on the lower layer below the aerating oxidation pond; the outlet pipelines of the two oxidation fans are communicated with each other and are provided with changeover valves. The invention has the advantage of providing a high-efficiency aerating and oxidizing method designed in specific to the defects that a desulfurated solution has high solid content and is unstable, and solid particles are small in particle size, high in settling velocity and complex in impurity constituents and easily block the aperture of an aerating system; and the aerating and oxidizing method has the advantages of low cost, simplicity, convenience for mounting and dismounting and capability of effectively preventing suspension from settling to block the system, and is suitable for aerating treatment device for oxidizing the flue gas desulfurization waste liquid.

Description

technical field [0001] The invention belongs to the treatment of waste water, in particular to an aeration device for oxidation and desulfurization waste liquid. technical background [0002] Aeration systems are widely used in various fields, mostly for biological treatment of sewage. People have studied aeration for nearly a hundred years. According to the oxygenation method, it can be divided into blast aeration and mechanical aeration. The blast aeration system is generally composed of air compressor, pipeline, and air diffusion device. The air diffusion device has various forms, such as micro-bubble, medium-bubble, large Bubbles and other types, the efficiency of the microporous diffusion device is the highest, and it is mostly made of porous materials such as ceramsite, coarse porcelain, etc. mixed with an appropriate binder and sintered. The disadvantage of this type of device is that the pressure loss is large and it is easy to block. The incoming air should be pre-...
