[0001] This utility model relates to the technical field of flue gas treatment equipment, specifically to a humidification tower suitable for cement desulfurization production lines. Background Technology

[0002] The desulfurization and humidification tower in cement production is one of the core pieces of equipment in the flue gas desulfurization system, mainly used to reduce the emissions of sulfur dioxide and particulate matter in flue gas.

[0003] Existing cement desulfurization humidification towers (semi-dry desulfurization efficiency enhancement and humidification device with application number 202220724306.1) improve desulfurization efficiency by setting multiple desulfurization reaction zones in the straight pipe section of the humidification tower. However, the desulfurization humidification tower does not have corresponding baffles installed inside to humidify and block the flue gas during the rising process, thus affecting the online efficient desulfurization and humidification of cement flue gas. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a humidification tower suitable for cement desulfurization production lines to solve the technical problem that existing cement desulfurization humidification towers do not have corresponding baffles installed inside to humidify and block the flue gas during the rising process, thus affecting the online efficient desulfurization and humidification of cement flue gas.

[0005] According to the technical solution provided in the embodiments of this application, a humidification tower applicable to a cement desulfurization production line includes a humidification tower body, the vertical part of which is provided with a number of baffle plates and a number of gathering plates to divide the vertical part into a number of reaction zones.

[0006] The barrier plate has an arc-shaped structure and is set on the top of the corresponding gathering plate in the vertical part. The bottom of the barrier plate is provided with an arc-shaped barrier groove, and a number of spray heads are provided in the arc-shaped barrier groove for spraying the gathered flue gas.

[0007] The gathering plate has a conical gathering groove at its bottom for gathering the rising flue gas inside the humidification tower, and an annular receiving groove at its top for collecting the liquid from the spray separation.

[0008] Furthermore, the barrier plate has a hollow structure inside.

[0009] Furthermore, the bottom of the barrier plate is provided with several guide strips for guiding the flow of the liquid that accumulates after the reaction.

[0010] Furthermore, the diameter of the barrier plate is larger than the diameter of the top opening of the gathering groove.

[0011] Furthermore, the bottom of the receiving trough is provided with several discharge holes, and each discharge hole is equipped with a corresponding discharge pipe.

[0012] Furthermore, a liquid inlet is provided at the top center of the barrier plate, and the liquid inlet is connected to the liquid inlet pipe for conveying the spray liquid.

[0013] Furthermore, the inlet pipe is connected to the spray liquid tank so that the water pump installed in the spray liquid tank can transport the spray liquid from the inlet pipe to each baffle plate, and then spray it out from the several spray heads set on each baffle plate.

[0014] In summary, the beneficial effects of this application are as follows:

[0015] 1. By setting several baffle plates and several gathering plates on the vertical part of the humidification tower body, so that each baffle plate is spaced at the top of each gathering plate, the flue gas gathered by the gathering plates is sprayed and atomized in a barrier manner, so that the flue gas can be fully mixed with the spray liquid, thereby improving the desulfurization efficiency and desulfurization quality of the humidification tower for cement flue gas.

[0016] Second, by setting the bottom of the baffle plate into an arc-shaped baffle groove, the baffle groove can block and spray the flue gas during the rising process. At the same time, several guide strips are also set in the baffle groove so that the liquid after spraying and desulfurization after rising can flow along the guide strips to the outer edge of the baffle plate, and then the desulfurized liquid can enter the receiving groove on the gathering plate along the outer side of the baffle plate, thereby improving the desulfurization efficiency and desulfurization quality of the humidification tower for cement flue gas.

[0024] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] A humidification tower suitable for cement desulfurization production lines, its structure is shown in Figures 1-5. It includes a humidification tower body 100, inside which a vertical section is equipped with several baffle plates 200 and several gathering plates 300. The baffle plates 200 and gathering plates 300 are arranged side-by-side and spaced apart along the vertical direction of the vertical section, thus dividing the vertical section into several reaction zones. This allows the humidification tower to efficiently desulfurize and humidify cement flue gas, improving the desulfurization efficiency and quality of the cement flue gas. The baffle plates 200 have an arc-shaped structure and are located at the top of the corresponding gathering plates 300 within the vertical section. The bottom of the baffle plates 200 also has an arc-shaped barrier. The trough 210, an arc-shaped barrier trough 210, is equipped with several spray heads 220. The spray liquid sprayed by the spray heads 220 is sprayed with the flue gas after it is gathered, so that the spray liquid is fully mixed with the flue gas, thereby performing flue gas desulfurization. The gathering plate 300 has a gathering trough 310 with a conical structure at its bottom. The bottom diameter of the gathering trough 310 is larger than the top diameter, so that the flue gas passing through the gathering trough 310 is gathered. The top of the gathering plate 300 is equipped with a ring-shaped receiving trough 320. The diameter of the receiving trough 320 is larger than that of the barrier plate 200, so that the desulfurized liquid dripping from the barrier plate 200 is collected in the receiving trough 320.

[0027] As a preferred embodiment, please refer to Figure 5. The baffle plate 200 has a hollow structure inside, so that the spray liquid delivered by the liquid inlet pipe 230 enters the cavity and is then sprayed out from several spray heads 220 connected to the cavity. This allows the flue gas gathered at the bottom of the baffle plate 200 to be fully mixed with the spray liquid, thereby improving the desulfurization quality and efficiency of cement flue gas.

[0028] As a preferred embodiment, please refer to Figure 4. The bottom of the barrier plate 200 is provided with a plurality of guide strips 240, and the plurality of guide strips 240 are arranged side by side and spaced apart along the bottom of the barrier groove 210, so that the sprayed liquid that accumulates after the reaction flows and is guided along the guide strips 240 and is quickly discharged from the barrier plate 200.

[0029] As a preferred embodiment, please refer to Figures 3 and 5. The diameter of the baffle plate 200 is larger than the diameter of the top opening of the gathering trough 310, so that the desulfurization liquid sprayed on the baffle plate 200 moves along several guide bars 240 to the outside of the baffle plate 200, and then the desulfurization liquid falls along the outside of the baffle plate 200 into the receiving trough 320.

[0030] As a preferred embodiment, please refer to Figures 4 and 5. The bottom of the receiving trough 320 is provided with several discharge holes, which are arranged side by side and spaced apart. Each discharge hole is equipped with a corresponding discharge pipe 330 so that the desulfurization liquid collected in the receiving trough 320 falls from the discharge pipe 330 to the bottom of the humidification tower body 100, thereby improving the desulfurization efficiency and quality of the humidification tower for cement flue gas.

[0031] As a preferred embodiment, please refer to Figures 1 and 2. A liquid inlet is provided at the top center of the baffle plate 200. The liquid inlet is connected to the liquid inlet pipe 230, which is connected to the spray liquid tank. This allows the water pump installed in the spray liquid tank to transport the spray liquid from the liquid inlet pipe 230 to each baffle plate 200, and then spray it out from a plurality of spray heads 220 provided on each baffle plate 200.

[0032] The working principle of the humidification tower applicable to cement desulfurization production lines of this utility model is as follows:

[0033] In the cement production process, the flue gas generated during the high-temperature firing of cement enters the humidification tower through the air inlet at the bottom of the tower and rises along the tower. During the rise of the flue gas, several baffle plates 200 and several gathering plates 300 are installed in the vertical part of the humidification tower body 100. These baffle plates 200 and gathering plates 300 are arranged side-by-side and spaced apart along the vertical part, with each baffle plate 200 positioned on top of its corresponding gathering plate 300. This allows the gathering plates 300 to gather the rising flue gas, thus slowing its ascent under the obstruction of the arc-shaped baffle plates 200. The baffle plate 200 is equipped with several spray heads 220 that spray atomized spray liquid. The flue gas is fully mixed with the spray liquid, and the rising flue gas is desulfurized by spraying. This improves the desulfurization efficiency and quality of the humidification tower for cement flue gas. The desulfurized liquid after spraying flows along several guide bars 240, moves to the outside of the baffle plate 200, and then falls into the receiving trough 320 on the gathering plate 300 at the bottom of the baffle plate 200. The desulfurized liquid is then discharged from several discharge pipes 330 at the bottom of the receiving trough 320 to the bottom of the humidification tower, thereby improving the desulfurization efficiency and quality of the humidification tower for cement.

[0034] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and solutions employed. Furthermore, the scope of the utility model involved in this application is not limited to the specific combination of the above-described technical features, but should also cover other technical solutions formed by any combination of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
