The desulfurizing tower is a necessary facility in a chemical plant related to sulfur emission. Wet desulfurization is a very common desulfurization method, and sulfur dioxide in waste gas is treated by spraying slurry.
The slurry spray header is one of the core components in the wet desulphurization system and is used for spraying slurry containing a medicament. However, the slurry containing the medicament is corrosive, and medicament particles and crystal particles in the slurry can flush the inner wall of the desulfurizing tower at any time under the extremely strong pressure of the circulating pump. The glass flake anticorrosive coating inside the desulfurizing tower is thinned and broken after being punched for several months, so that the tower body is corroded, and the service life of the desulfurizing tower is seriously influenced.

The utility model discloses a further set up to: the cross section of the pendant is L-shaped, and the wear-resistant sheet is provided with a flanging attached to the bottom of the pendant.
The utility model discloses a further set up to: the pendant with the connecting piece is stainless steel.
The utility model discloses a further set up to: the connecting piece is a bolt.
The utility model also provides a desulfurizing tower, be provided with a plurality of in the desulfurizing tower and spray the layer, still set up a plurality of as above-mentioned wear-resisting dado, each wear-resisting dado is located each spray the layer under.
The beneficial effects of the utility model are that:
the wear-resistant retaining wall can be arranged right below the spraying layer in the desulfurizing tower and is used for bearing the scouring of slurry, improving the durability of the desulfurizing tower and prolonging the service life of the desulfurizing tower. If the wear-resisting plate is damaged, the wear-resisting plate can be replaced at any time, and the replacement process is simple and convenient.

Detailed Description
Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.
Example 1
Referring to fig. 1-3, the present embodiment provides a wear-resistant retaining wall, which includes a plurality of protective units, each of which is surrounded in a ring shape and is used for being fixed on the inner wall of the desulfurizing tower 5. The protection unit includes: pendant 1, wearpad 2 and a plurality of connecting piece 3.
The hanger 1 is fixed on the inner wall of the desulfurizing tower 5 in a welding mode. The cross section of the pendant 1 is L-shaped. The wear-resistant plate 2 is arranged right below the pendant 1, and the wear-resistant plate 2 is provided with a flanging attached to the bottom of the pendant 1. The pendant 1 and the wear-resistant sheet 2 are fixedly connected through a plurality of connecting pieces 3, and the connecting pieces 3 are bolts.
The hanger 1, the connector 3 and the wear-resistant sheet 2 are all made of stainless steel, and a wear-resistant layer is arranged on the surface of the wear-resistant sheet 2. The wear-resistant layer is not coated by paint, but carbide is driven into the surface of the metal by a supersonic spraying or plasma spraying mode in the prior art, so that the wear-resistant layer with excellent wear resistance is formed.
In specific implementation, the wear-resistant retaining wall can be arranged right below the spraying layer 4 in the desulfurizing tower 5 and used for bearing the scouring of slurry, so that the durability and the service life of the desulfurizing tower 5 are improved. Tests prove that the glass flake anticorrosive paint can be used for 10-15 times more than the original glass flake anticorrosive paint under the same scouring force and scouring time. If the wear-resisting plate is damaged, the wear-resisting plate can be replaced at any time, and the replacement process is simple and convenient.
Example 2
Referring to fig. 4, the present embodiment discloses a desulfurization tower 5, which is internally provided with three spray layers 4 and three wear-resistant retaining walls. Each wear-resistant protecting wall is respectively positioned under each layer of spraying layer 4, and the wear-resistant protecting walls bear the scouring of the slurry and bear the parts except the scouring positions, so that the coating has better corrosion resistance. The present embodiment has the advantageous effects of embodiment 1.
