Technical Field

[0001] The utility model relates to the field of desulfurization towers, in particular to a flue gas desulfurization tower for white carbon black production. Background Art

[0002] Carbon black is a white amorphous silicate material, the main component of which is silicon dioxide (SiO2). Flue gas desulfurization tower is a device used to reduce sulfur dioxide (SO2) in industrial emissions. It removes SO2 from flue gas through a chemical absorption process to reduce air pollution. In the production of white carbon black, a desulfurization tower is needed to desulfurize oxygen to reduce air pollution.

[0003] When the flue gas generated during the production of white carbon black is removed, it is necessary to use the method of spraying limestone water for desulfurization. The flue gas is passed into the desulfurization tower, and the limestone water is sprayed to react with the flue gas. However, since the flue gas floats upward, part of the flue gas fails to fully contact with the limestone water, which reduces the desulfurization effect. Utility Model Content

[0011] According to the flue gas desulfurization tower for white carbon black production, the connecting pipe is threadedly connected to the mounting ring.

[0012] Beneficial effects:

[0022] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0023] Reference Figure 1-4 A flue gas desulfurization tower for white carbon black production includes a tower body 1: a smoke inlet pipe 2 is fixedly connected to the left side of the tower body 1, a smoke outlet pipe 3 is fixedly connected to the right side of the tower body 1, a spray unit 4 is arranged on the inner side of the tower body 1, the smoke outlet pipe 3 is located in the upper area of ​​the smoke inlet pipe 2, so that the smoke moves upward, and the upper spray unit 4 sprays limestone water to perform desulfurization operation.

[0024] The spray unit 4 includes a cover plate 401, which is arranged on the upper side of the tower body 1. A motor 404 and a water pump 403 are fixedly connected to the upper side of the cover plate 401. A rotating pipe 406 is rotatably connected to the lower side of the cover plate 401. A connecting pipe 405 is arranged between the water pump 403 and the rotating pipe 406. A mounting ring 410 is fixedly connected to the outer side of the rotating pipe 406. A connecting pipe 407 is arranged on the inner side of the mounting ring 410. A plurality of spray heads 408 are fixedly connected to the lower side of the connecting pipe 407. Gears 409 are fixedly connected to the outer side of the lower output end of the motor 404 and the outer side of the rotating pipe 406. A plurality of the connecting pipes 407 and the spray heads 408 are arranged. Two gears 409 are meshed and connected. The connecting pipe 405 is rotatably connected to the rotating pipe 406. During desulfurization, the motor 404 and the water pump 403 are started, and one end of the water pump 403 is connected to a container for holding limestone water (not shown in the figure), so that the water pump 403 pumps out the limestone water, and passes the limestone water into the rotating pipe 406 through the connecting pipe 405, and then through the connecting pipe 407, multiple spray heads 408 spray the limestone water, so that the limestone water and the flue gas can contact and react. At the same time, the motor 404 drives the gear 409 to rotate. Since the two gears 409 are meshed and connected, the motor 404 drives the rotating pipe 406 to rotate, the rotating pipe 406 drives the connecting pipe 407 to rotate, and the connecting pipe 407 drives the spray head 408 to rotate, so that the spraying range of the spray head 408 is increased, the limestone water is fully in contact with the flue gas, and the desulfurization effect is increased.

[0025] A fixing ring 402 is fixedly connected to the outer side of the cover plate 401, and a supporting ring 5 is fixedly connected to the outer side of the tower body 1. Bolts are arranged between the supporting ring 5 and the fixing ring 402. The connecting pipe 407 is threadedly connected to the mounting ring 410. When the sprinkler head 408 is used for a long time, the sprinkler head 408 is prone to clogging. At this time, the bolts are loosened to separate the fixing ring 402 from the supporting ring 5, and then the cover plate 401 is removed to facilitate the removal of the connecting pipe 407 from the tower body 1. Then, the connecting pipe 407 is rotated to loosen the connecting pipe 407 to facilitate the cleaning of the sprinkler head 408.

[0026] Working principle: When in use, the staff first passes the flue gas into the tower body 1 through the smoke inlet pipe 2, and then starts the water pump 403 and the motor 404. Under the action of the gear 409 and the rotating pipe 406, the motor 404 drives the connecting pipe 407 on the rotating pipe 406 to rotate, and the connecting pipe 407 drives the spray head 408 to rotate. At the same time, the water pump 403 passes limestone water into the rotating pipe 406, so that the spray head 408 sprays out limestone water, which facilitates the full contact between the flue gas and the limestone water, thereby increasing the flue gas desulfurization effect in the white carbon black production process.

[0027] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
