Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization towers, in particular to a desulfurization tower bottom disturbance system. Background Art

[0002] A desulfurization tower is a tower-type equipment for desulfurization of industrial waste gas. A packing layer is usually placed inside the desulfurization tower. When the waste gas passes through the packing layer from the bottom of the tower at a low flow rate, hydrogen sulfide (H2S) is oxidized into sulfur or sulfur oxides and remains in the packing layer. The purified waste gas is discharged from the top of the container.

[0003] As shown in the application document of the prior art publication number CN207478294U, it includes a tower body, a liquid collecting tank arranged at the bottom of the tower body, a smoke inlet, a smoke outlet and a spray component; it is characterized in that: a diffusion component is arranged between the first spray component and the second spray component, and the diffusion component includes a smoke dispersing plate with multiple smoke dispersing holes and a smoke dispersing sheet that can swing left and right on the smoke dispersing plate; the side wall of the tower body is provided with a switch component connected to the liquid collecting tank; the bottom of the liquid collecting tank is provided with an inclined surface. This technical solution sets a switch component at the bottom of the liquid collecting tank, which can facilitate the discharge of the liquid in the liquid collecting tank, and sets an inclined surface in the liquid collecting tank, which facilitates the liquid in the liquid collecting tank to flow into the switch component, and then facilitates the flow out of the switch component, which facilitates the discharge of liquid, keeps the liquid collecting tank clean, avoids residue, causes corrosion of the liquid collecting tank, and prolongs the service life of the device.

[0004] By then, the above technical solution can only discharge the residual slurry at the bottom of the desulfurization tower, resulting in that the technical solution does not fully treat the slurry, and the technical solution cannot prevent the slurry from accumulating to form a "slag mountain", which will affect the desulfurization effect of the technical solution. Utility Model Content

The disturbance main pipe then transports the slurry to a disturbance nozzle through a disturbance branch pipe, and is sprayed out by the disturbance nozzle. In this way, the slurry can be kept in a disturbed state all the time to avoid the formation of a "slag mountain", and the disturbed slurry can be fully mixed with oxygen to improve the oxidation efficiency of the slurry, thereby facilitating the formation of gypsum, so as to solve the problems arising from the above-mentioned background technology.
