Problems solved by technology
[0003] The purpose of the present invention is to overcome the problems existing in the prior art that due to the unified setting of anti-corrosion structures in the conventional anti-corrosion process, there are weakly corrosive parts with strong anti-corrosion structures, while structures that are easily corroded cannot reach the average anti-corrosion structure of the desulfurization device. Using time, resulting in the inability to run for a long period of time, the technical problems of heavy maintenance, provide a desulfurization absorption tower, circulation tank, desulfurization device and desulfurization system, the desulfurization absorption tower, circulation tank, desulfurization device and desulfurization system have different Corrosion mechanisms are different for different parts, and specific anti-corrosion construction techniques and construction materials are formulated to solve the problem of frequent leakage of tower tanks and improve the technical effect of the desulfurization system's operating cycle

The invention relates to the field of corrosion-resistant protection processes of desulfurization systems, and discloses a desulfurization absorption tower, a circulating tank, a desulfurization device and a desulfurization system. The desulfurization absorption tower comprises an inlet flue (1), a tower body (2) and an outlet flue (3), wherein the tower body (2) can be used for arranging the circulating tank, and the tower body (2) is arranged between the inlet flue (1) and the outlet flue (3) in a communicating mode; and a corrosion-resistant coating layer (4) is arranged on the inner surface of the inlet flue (3). The technical problems that due to the fact that an anti-corrosion structure is uniformly arranged through a conventional anti-corrosion technology, the anti-corrosion structure of a part with weak corrosivity is high, the average anti-corrosion structure service time of a desulfurization device cannot be achieved through a structure prone to corrosion, long-period operation cannot be conducted, and the maintenance intensity is large are solved.
Description
technical field [0001] The invention relates to the field of anti-corrosion protection technology for desulfurization systems, in particular to a desulfurization absorption tower, a circulation tank, a desulfurization device and a desulfurization system. Background technique [0002] The existing desulfurization absorption tower's inlet and outlet flue and circulation tank have poor anti-corrosion effect, resulting in frequent leakage, low manufacturing standards, and easy to corrode the body structure of the desulfurization absorption tower and circulation tank, and the circulation tank requires a lot of financial resources. , material resources and manpower to eliminate leakage points, and the maintenance cost is high. Due to the different anti-corrosion requirements of desulfurization units in different locations, the conventional anti-corrosion process is unified in the setting of anti-corrosion structures, and the parts with weak corrosion have strong anti-corrosion str...
