Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization towers, in particular to an internal anti-corrosion component of a raw material desulfurization tower shell. Background Art

[0002] Desulfurization tower is a tower equipment for desulfurization of industrial waste gas. Desulfurization tower was originally built with granite and was most widely used. It uses the principle of water film desulfurization and dust removal. The advantage is that it is easy to maintain, and different dust removal agents can be prepared to achieve the effects of dust removal and desulfurization (denitrification). With the development of FRP technology, desulfurization towers are gradually changed to be made of FRP. Compared with granite desulfurization towers, FRP desulfurization towers have low cost, easy processing, no rust and no rot, and light weight, so they have become the development trend of desulfurization towers in the future.

[0003] Flue gas needs to be desulfurized during cement production and processing. Currently, the desulfurization tower will cause inner wall corrosion due to acidic substances in the flue gas and high-temperature oxidation during use. At the same time, the desulfurization solvent is also corrosive, and the sprayed desulfurization solvent will also cause inner wall corrosion. Therefore, the utility model provides an internal anti-corrosion component of the raw meal desulfurization tower shell. Utility Model Content

[0004] The purpose of the utility model is to provide an internal anti-corrosion component of a raw meal desulfurization tower shell, which has the advantages of reducing the flue gas temperature, neutralizing the acidic substances in the flue gas with an alkaline solution, and preventing corrosion inside the desulfurization tower, thereby solving the problems raised by the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an internal anti-corrosion component of a raw meal desulfurization tower shell, comprising a desulfurization tower body, a cooling water tank and a solution tank, wherein the cooling water tank is installed in the desulfurization tower body, and a water outlet pipe and a water inlet pipe are installed at the side end of the desulfurization tower body, and the water outlet pipe and the water inlet pipe are both connected to the cooling water tank;

[0006] The solution tank is installed in the cooling water tank, and a cooling water cavity is formed between the solution tank and the cooling water tank. A liquid discharge pipe and a liquid inlet pipe are installed at the side end of the desulfurization tower body. The liquid inlet pipe is located above the liquid discharge pipe. A flue gas inlet pipe extending into the solution tank is installed at the side end of the desulfurization tower body.

[0007] A delivery pump is arranged at the upper end of the solution tank, and a liquid extraction pipe and a delivery pipe are arranged on the delivery pump. The liquid extraction pipe extends into the solution tank, and the end of the delivery pipe extends to the smoke inlet pipe where a spray head is installed.

[0008] Preferably, the water outlet pipe and the water inlet pipe are symmetrically distributed about the cooling water tank, and valves are provided on both the water outlet pipe and the water inlet pipe.

[0009] Preferably, the liquid discharge pipe and the liquid inlet pipe are both connected to the solution tank, and valves are provided on the liquid discharge pipe and the liquid inlet pipe.

[0010] Preferably, a rotating shaft is rotatably mounted on the inner wall of the upper end of the solution tank, and stirring rods equidistantly distributed are mounted on the rotating shaft.

[0011] Preferably, a driving device is installed at the upper end of the solution tank, and the main shaft of the driving device is connected to the axis of the rotating shaft.

[0012] Preferably, a smoke exhaust pipe communicating with the solution tank is installed on one side of the upper end surface of the solution tank.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] When the flue gas enters the flue gas inlet pipe, the alkaline solvent can be transported to the spray head through the operation of the delivery pump, and then it can be sprayed from the spray head to spray the flue gas. Bubbles will be formed after the flue gas enters the solution tank. The large bubbles can be broken into small bubbles by stirring with the stirring rod, so that the flue gas can fully contact with the solution and neutralize the acidic substances in the flue gas. At the same time, the flue gas temperature can be reduced to prevent the flue gas and solvent from corroding the inner wall of the desulfurization tower. BRIEF DESCRIPTION OF THE DRAWINGS
