Description

[0001] The utility model relates to the technical field of desulfurization devices, in particular to a flue gas desulfurization device based on a rotary spray semi-dry type. Background Art

[0002] With the development of modern industry, a large amount of sulfur-containing flue gas will be produced. In order to make the flue gas meet the emission standards, a spray desulfurization device, also called a spray tower, is required. The sulfur substances in the flue gas are treated using a spray tower-type rotating spray device to dissolve the sulfur in the water.

[0003] The existing spray tower has the problem that the water vapor produced by purifying sulfur substances will affect the flue gas purification treatment results;

[0004] The reason for this problem is that the principle used by the spray tower is to use a rotating spray device in the spray tower to atomize water, so as to mix water with flue gas, and the water vapor will blend with the sulfur substances in the flue gas, thereby purifying the sulfur substances in the exhaust gas. During the desulfurization purification process, a large number of water molecules will remain in the flue gas, and the water molecules will be discharged from the spray tower along the outlet pipe. At this time, some sulfur substances will be discharged from the spray tower together with the water vapor and the flue gas. At the same time, the flue gas needs to undergo the next purification process after treating the sulfur substances. If a large number of water molecules enter the next purification process together with the flue gas, it will cause secondary pollution to the next purification process. Therefore, we propose a flue gas desulfurization device based on rotary spray semi-dry type. Utility Model Content

The drying mechanism includes a drying treatment box 2, which is installed at the end of the air outlet pipe 102. The drying treatment box 2 is used for drying the exhaust gas. A dry particle storage net box 205 is arranged inside the drying treatment box 2. Dry particles are arranged inside the dry particle storage net box 205. The dry particles are used to absorb moisture in the gas. A rotating plate 202 is rotatably arranged above the dry particle storage net box 205, and the rotating plate 202 is used to disperse the gas.

[0026] The flue gas undergoes preliminary impurity purification from the inside of the gas impurity purification box 101, and then enters the inside of the spray purification tower body 1 from the gas impurity purification box 101. The water mist generated by the rotating spray device inside the spray purification tower body 1 is mixed with the flue gas. At this time, the sulfur substances in the flue gas will be mixed with water, and the water will be desulfurized and purified.

[0027] The flue gas is treated by the spray purification tower body 1. The purified flue gas and part of the water vapor enter the drying treatment box 2 from the position of the exhaust pipe 102. At this time, the rotary driver 209 will drive the rotating plate 202 to rotate. The rotating plate 202 rotates to disperse the gas to the surrounding positions of the drying treatment box 2, and enter the position of the dry particle storage net box 205 from the surrounding positions of the drying treatment box 2. Dry particles are placed inside the dry particle storage net box 205. The dry particles dry the moisture in the gas. Then the gas will enter the inside of the drying net plate 206. The inside of the drying net plate 206 is provided with drying material to quickly absorb excess water vapor, thereby further drying the gas.

[0028] A gas impurity purification box 101 is arranged on the side of the spray purification tower body 1, an installation box 201 is fixedly connected to the interior of the drying treatment box 2, a dry particle storage net box 205 is arranged inside the installation box 201, a support rod 208 is fixedly connected to the interior of the drying treatment box 2, a drying net plate 206 is sleeved on the outside of the support rod 208, and the drying net plate 206 is arranged below the installation box 201, and the drying net plate 206 is arranged below the dry particle storage net box 205.

[0031] The rotary driver 209 is a rotary driving device that can drive the rotary disk 211 to rotate inside the function box 204, thereby driving the rotary plate 202 to rotate. During the rotation of the rotary plate 202, an outward airflow is generated, thereby driving the gas to the surroundings of the drying treatment box 2, thereby dispersing the gas.

[0032] In summary, compared with the prior art, the present invention has the following beneficial effects:
