Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization equipment, in particular to a wet desulfurization device. Background Technique

[0002] Wet desulfurization features that the desulfurization system is located at the end of the flue and after the dust collector. The reaction temperature during the desulfurization process is lower than the dew point, so the flue gas after desulfurization needs to be reheated before being discharged. Since it is a gas-liquid reaction, its desulfurization reaction speed is fast, the efficiency is high, and the utilization rate of desulfurization additives is high. For example, when lime is used as the desulfurization agent, when Ca / S = 1, a desulfurization rate of 90% can be achieved.

[0003] The patent publication number CN206295798U discloses a wet desulfurization device with a floating valve sieve hole composite tray, including a tower body. A slurry pool is arranged below the interior of the tower body, stirring pumps are arranged on both sides of the slurry pool, an absorption tower inlet is arranged above the oxidation equipment on the tower body, and a floating valve sieve hole composite tray is arranged above the absorption tower inlet inside the tower body. The utility model adopts a floating valve structure that can carry the slurry, increase the slurry residence time, and increase the solubility of limestone; the flue gas enters the slurry layer horizontally from the side of the valve orifice, increasing the flue gas flow path, having a long gas-liquid contact time, and improving the capture efficiency of sulfur dioxide and dust; at the same time, after the flue gas is washed by the slurry layer, the liquid level drop is small and the entrainment of mist is small, which can reduce the dust content at the outlet of the absorption tower; uniformly adding sieve holes around the original floating valve can evenly distribute the flue gas flow field and eliminate the phenomenon of flue gas short circuit; at the same time, it can increase the upper limit of the gas phase load, achieving the effects of increasing production capacity, expanding energy, and saving renovation investment.

[0004] During the use of the prior art CN206295798U, although there are many benefits, there are still the following problems. It lacks a stirring device for the atomized liquid, resulting in poor mixing uniformity between the waste gas and the atomized liquid, affecting the desulfurization quality of the waste gas.

A rotating shaft is rotatably installed on one side of the inner wall of the connecting cover. Stirring rods distributed in a circular array are installed on the outer wall of the rotating shaft.

The desulfurized waste gas is discharged through the exhaust pipe after being treated by the demister. When the liquid flows inside the connecting cover, it drives the impeller to rotate in a circle, thereby driving the rotating shaft and the stirring rod to rotate in a circle, achieving the purpose of stirring and mixing the liquid and the waste gas.

[0010] Preferably, one side of the outer wall at the upper end of the outer shell is inserted and installed with an exhaust pipe, and the exhaust pipe is communicated with the interior of the outer shell. The desulfurized waste gas inside the outer shell is discharged through the exhaust pipe.

[0011] Preferably, a demister is installed on one side at the upper end of the inner wall of the outer shell, and the demister is located above the connecting cover. The demister can filter the moisture in the waste gas.

[0012] Preferably, one side of the inner wall of the outer shell is inserted and installed with a water inlet pipe, and the water inlet pipe is communicated with the interior of the connecting cover.
