Description

Atomizing mechanism suitable for cement desulfurization and humidification towers Technical Field

[0001] This utility model relates to the field of cement production equipment technology, specifically to an atomization mechanism applicable to cement desulfurization and humidification towers. Background Technology

[0002] The desulfurization and humidification tower (also known as the spray drying desulfurization tower or SDA tower) in cement production is one of the core pieces of equipment in the flue gas desulfurization system, mainly used to reduce sulfur dioxide (SO2) and particulate matter emissions in flue gas.

[0003] Existing cement desulfurization humidification towers (such as the semi-dry desulfurization tower efficiency-enhancing and humidification device with application number 202220724306.1) achieve efficient and multi-zone humidification and desulfurization within the tower by setting interval-shaped humidification units inside. However, the atomizing nozzles inside the cement desulfurization humidification tower are located at the edge of the tower body, causing the desulfurizing agent to only contact the flue gas at the edge and preventing mixing with the flue gas in the middle, thus affecting the desulfurization and humidification quality of the cement flue gas by the atomization mechanism. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide an atomization mechanism suitable for cement desulfurization and humidification towers, in order to solve the problem that the existing atomization mechanism of cement desulfurization and humidification towers is set at the edge inside the tower body, so that the desulfurizing agent can only contact the flue gas at the edge and cannot mix with the flue gas in the middle, thereby affecting the desulfurization and humidification quality of cement flue gas by the atomization mechanism.

[0005] According to the technical solution provided in the embodiments of this application, an atomizing mechanism is applicable to a cement desulfurization and humidification tower, including an atomizing mechanism installed inside the tower body for atomizing and spraying desulfurizing agent inside the tower body.

[0006] The atomizing mechanism includes a first atomizing component, a second atomizing component, a delivery pipe, and a desulfurizing agent tank. The first atomizing component and the second atomizing component have compatible structures and are correspondingly arranged along the vertical direction of the tower body. The first atomizing component and the second atomizing component are respectively connected to the delivery pipe, and the delivery pipe is connected to the desulfurizing agent tank, so that the liquid desulfurizing agent in the desulfurizing agent tank is delivered from the delivery pipe into the first atomizing component and the second atomizing component, and atomized and sprayed into the tower body within the first atomizing component and the second atomizing component.

[0007] The first atomizing component includes a plurality of atomizing tubes and a liquid inlet pipe. The plurality of atomizing tubes are arranged side by side and spaced apart on the liquid inlet pipe for multi-directional atomization within the tower body.

[0008] The atomizing tube has an arc-shaped structure and extends along the inner wall of the tower to the center, and is used for atomizing different diameters inside the tower.

[0009] Furthermore, the atomizing tube is also equipped with several atomizing nozzles for atomizing and spraying the desulfurizing agent inside the atomizing tube.

[0010] Furthermore, the inlet pipe has a ring-shaped structure.

[0011] Furthermore, the first atomizing component also includes a booster pump, which is installed on a branch pipe on the liquid inlet pipe for boosting the gas and pressurizing of the desulfurizer entering the liquid inlet pipe.

[0012] Furthermore, the infusion tube is equipped with two corresponding branch tubes, each branch tube being connected to the inlet tube on the first atomizing component and the second atomizing component, respectively.

[0013] Furthermore, a flue gas equalization plate is also provided at the bottom air inlet of the tower body to ensure that the flue gas entering the tower body is evenly distributed.

[0014] Furthermore, the spiral direction of the atomizing tube is opposite to the rotation direction of the flue gas inside the tower.

[0015] In summary, the beneficial effects of this application are as follows:

[0016] 1. By setting the traditional fixed atomizing gun atomizing structure into an atomizing structure with an arc-shaped atomizing tube, the arc-shaped atomizing tube extends along the inner wall of the tower to the center, so that the atomizing tube can atomize and desulfurize the flue gas at different depths inside the tower, thereby improving the atomization and desulfurization quality of the flue gas inside the cement desulfurization and humidification tower.

[0017] Second, by setting the spiral direction of the atomizing tube to be opposite to the rotation direction of the flue gas inside the tower, the desulfurizing agent droplets sprayed by several atomizing nozzles on the atomizing tube are mixed countercurrently with the flue gas rotating and rising inside the tower, and then react with the sulfides in the flue gas to form solid sulfides, thereby improving the atomization desulfurization quality of the flue gas inside the cement desulfurization and humidification tower.

[0018] Third, by setting up two corresponding first atomizing components and second atomizing components, the two sets of atomizing components can perform two-stage atomization desulfurization reaction on the flue gas inside the tower, thereby improving the atomization desulfurization quality and efficiency of the atomization mechanism on the flue gas inside the cement desulfurization and humidification tower.

[0026] An atomizing mechanism suitable for cement desulfurization and humidification towers, its structure is shown in Figures 1-3, including an atomizing mechanism 100 installed inside the tower body 200 for atomizing and spraying the desulfurizing agent within the tower body 200, so that the desulfurizing agent mixes with the cement flue gas to form solid sulfides, thereby completing flue gas desulfurization; the atomizing mechanism 100 includes a first atomizing component 110, a second atomizing component 120, a liquid delivery pipe 130, and a desulfurizing agent tank 140, the first atomizing component 110 and the second atomizing component 120... The structures are compatible, and the first atomizing component 110 and the second atomizing component 120 are correspondingly arranged along the vertical direction of the tower body 200, so that the two sets of atomizing components can perform a two-stage atomization desulfurization reaction on the flue gas inside the tower body 200, thereby improving the atomization desulfurization quality and efficiency of the flue gas inside the tower body 200 of the cement desulfurization humidification tower. The first atomizing component 110 and the second atomizing component 120 are respectively connected to the liquid delivery pipe 130, and the liquid delivery pipe 130 is connected to the desulfurizing agent tank 14. The system is connected to a 0-connection, allowing the liquid desulfurizing agent in the desulfurizing agent tank 140 to be pumped from the delivery pipe 130 into the first atomizing component 110 and the second atomizing component 120. The agent is then atomized in the first and second atomizing components 110 and sprayed into the tower body 200, thereby desulfurizing the flue gas within the tower body 200. The first atomizing component 110 includes several atomizing pipes 111 and an inlet pipe 112. The atomizing pipes 111 are arranged side-by-side and spaced apart from each other in the inlet pipe. On 112, the spiral direction of the atomizing tube 111 is opposite to the rotation direction of the flue gas inside the tower body 200, thereby enabling multiple atomizing tubes 111 to perform multi-directional atomization desulfurization inside the tower body 200; the atomizing tube 111 has an arc-shaped structure and extends along the inner wall of the tower body 200 to the center, thereby atomizing the flue gas of different diameters and depths inside the tower body 200, thereby improving the atomization desulfurization quality and efficiency of the atomization mechanism 100 for the flue gas inside the cement desulfurization humidification tower body 200.

[0027] As a preferred embodiment, please refer to Figure 3. The atomizing tube 111 is also provided with a number of atomizing nozzles 113 so that the desulfurizing agent entering each atomizing tube 111 is evenly sprayed out from each atomizing nozzle 113, thereby making the atomized desulfurizing agent evenly mixed with the flue gas rising inside the tower body 200, thereby improving the atomization desulfurization quality of the flue gas inside the tower body 200 of the cement desulfurization and humidification tower by the atomizing mechanism 100.

[0028] As a preferred embodiment, please refer to Figure 3. The liquid inlet pipe 112 has a ring structure so that the atomizing liquid can be evenly introduced into each atomizing pipe 111 connected to the liquid inlet pipe 112.

[0029] As a preferred embodiment, please refer to Figures 1 and 2. The infusion pipe 130 is equipped with two corresponding branch pipes 115. Each branch pipe 115 is connected to the inlet pipe 112 of the first atomizing component 110 and the second atomizing component 120, respectively. The first atomizing component 110 and the second atomizing component 120 also include booster pumps 114. Each booster pump 114 is installed on the corresponding branch pipe 115, thereby increasing the gas and pressure of the desulfurizing agent entering the inlet pipe 112, so that the desulfurizing agent is sprayed out from the atomizing nozzle 113 as uniform small droplets and fully mixed with the flue gas in the tower body 200, thereby improving the desulfurization quality of the flue gas inside the cement desulfurization humidification tower body 200.

[0030] As a preferred embodiment, please refer to Figures 1 and 2. A flue gas equalization plate 210 is also provided at the bottom air inlet inside the tower body 200 so that the flue gas entering the tower body 200 is evenly distributed by the flue gas equalization plate 210, so that the flue gas rises evenly inside the tower body 200. This allows the flue gas to mix with the desulfurizing agent droplets evenly sprayed by the atomizing mechanism 100 during the rising process, thereby improving the atomization quality of the flue gas inside the cement desulfurization and humidification tower body 200 by the atomizing mechanism 100.

[0031] The working principle of the atomizing mechanism 100 of the cement desulfurization and humidification tower of this utility model is as follows:

[0032] During the desulfurization process of the flue gas inside the cement desulfurization and humidification tower body 200 by the atomizing mechanism 100, the high-temperature flue gas enters the tower body 200 from the flue gas inlet at the bottom of the tower body 200 and spirals upwards inside the tower body 200 under the uniform distribution of the flue gas uniform plate 210 at the bottom of the tower body 200. The tower body 200 is equipped with a first atomizing component 110 and a second atomizing component 120 of the atomizing mechanism 100, so that the liquid desulfurizing agent in the desulfurizing agent tank 140 is transported into the liquid delivery pipe 130 by the water pump, and then enters the branch pipes 115 on the first atomizing component 110 and the second atomizing component 120 from each branch pipe 115. The booster pump 114 installed on each branch pipe 115 is started to pressurize and aerate the transported desulfurizing agent, so that the desulfurizing agent enters each liquid inlet pipe 112. The liquid enters the arc-shaped atomizing tube 111 installed on each inlet pipe 112. The arc-shaped atomizing tube 111 extends along the inner wall of the tower body 200 to the center, so that the atomizing tube 111 can atomize and desulfurize the flue gas at different depths inside the tower body 200, thereby improving the atomization and desulfurization quality of the flue gas inside the tower body 200 of the cement desulfurization and humidification tower by the atomizing mechanism 100. At the same time, the spiral direction of the atomizing tube 111 is set to be opposite to the rotation direction of the flue gas inside the tower body 200, so that the small droplets of desulfurizing agent sprayed by several atomizing nozzles 113 on the atomizing tube 111 mix countercurrently with the flue gas rotating and rising inside the tower body 200, and then react with the sulfides in the flue gas to form solid sulfides, thereby improving the atomization and desulfurization quality of the flue gas inside the tower body 200 of the cement desulfurization and humidification tower by the atomizing mechanism 100. The two first atomizing components 110 and the second atomizing component 120 are correspondingly arranged inside the tower body 200 so that the two sets of atomizing components can perform two-stage atomization desulfurization reaction on the flue gas inside the tower body 200, thereby improving the atomization desulfurization quality and atomization desulfurization efficiency of the flue gas inside the tower body 200 of the cement desulfurization and humidification tower of the atomizing mechanism 100.

[0033] 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.
