Description

Technical Field

[0001] The present application relates to the technical field of spray towers, and in particular to a spray structure of a spray tower. Background Art

[0002] Spray towers, as an important exhaust gas treatment device, are widely used in various industries, including chemical, metallurgy, and electric power. They remove harmful substances from exhaust gases through direct contact between the spray liquid and the exhaust gas. Currently, mainstream spray towers on the market mostly use a simple spray head combined with a packing layer. This approach makes it difficult to ensure uniform airflow distribution throughout the tower, especially for spray towers with non-circular cross-sections. Uneven airflow distribution can lead to poor spraying performance in certain areas, affecting overall purification efficiency. Utility Model Content

[0003] In order to solve the problem that existing spray towers mostly use a simple combination of a spray head and a packing layer, which makes it difficult to ensure uniform distribution of airflow throughout the tower, the present application provides a spray structure for a spray tower.

[0004] The spray structure of a spray tower provided in this application adopts the following technical solution:

[0005] A spray structure of a spray tower, comprising a spray tower and a spray structure, wherein a plurality of the spray structures are arranged in the spray tower, and the spray structure comprises a spray pipe and a gas collection spray assembly;

[0006] The spray pipe fitting is arranged in the spray tower, and the spray pipe fitting includes a coil arranged in the spray tower and is used for spraying water supply;

[0007] The gas collecting spray assembly is arranged on the lower side of the coil in the spray tower. The gas collecting spray assembly includes an air flow guide plate arranged in the spray tower, which is used to limit the cross-sectional area of ​​the rising air flow. Several overflow pipes are provided on the air flow guide plate to discharge the spray liquid received by the air flow guide plate.

[0008] Preferably, an air outlet is provided at the top between the two spray pipes on the spray tower, and an air inlet is provided below the spray structure on the spray tower.

[0009] Preferably, a layer plate is provided between two adjacent spray structures.

[0010] Preferably, a plurality of spray heads are provided at the lower end of the coil for atomizing and spraying the spray liquid.

[0011] Preferably, an impact plate with drainage holes is provided on the lower side of the airflow guide plate, which is used for the overflow spray liquid to collide with the plate surface and disperse into fine water droplets. The airflow guide plate includes an air collecting hood arranged on the spray tower, and an air guide pipe is provided on the top of the air collecting hood.

[0012] In summary, this application has the following beneficial technical effects:

[0013] By co-using spray pipes and gas collection spray components, the variable diameter gas collection hood is used to reduce the cross-sectional area of ​​the rising airflow, and then the airflow is guided by the air guide pipe, so that the spray head can spray the passing airflow in a unified and concentrated manner, avoiding the occurrence of spraying dead corners and affecting the spraying effect. At the same time, the spray liquid received by the airflow guide plate is discharged by gravity through the overflow pipe, and the spray liquid collides with the impact plate to form fine water droplets that come into contact with the gas. Compared with the existing technology, it has the advantages of high spraying efficiency and good purification effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The embodiment of the present application discloses a spray structure of a spray tower. Figure 1-3 , a spray structure of a spray tower includes a spray tower 1, several spray structures are installed on the inner side of the spray tower 1, an air inlet 2 is provided on the side of the spray tower 1, the air inlet 2 is located below the lowest spray structure, and an air outlet 3 is installed on the top of the spray tower 1, and the air outlet 3 is connected with the external exhaust gas treatment equipment, so that the air flow passes through the spray structure in sequence during the rising process to realize the spray treatment of the exhaust gas, the spray structure includes a spray pipe 4 and a gas collecting spray assembly 5, the spray pipe 4 is located above the gas collecting spray assembly 5, and the gas collecting spray assembly 5 includes an airflow guide plate 502 installed in the spray tower 1, and several overflow pipes 503 are installed on the airflow guide plate 502. The cross-sectional area of ​​the rising airflow is reduced by the variable diameter airflow guide plate 502, so that the airflow is concentrated just below the spray pipe 4, which facilitates full contact between the spray liquid and the gas.

[0020] Reference Figure 2A layer plate 6 is installed between two adjacent spray structures. The layer plate 6 adopts the commonly used structural design of installing a packing layer or a swirl plate above the filter plate to increase the gas-liquid contact area, promote uniform distribution of gas and liquid, and improve the spray treatment effect.

[0021] Reference Figure 3 The air flow guide plate 502 includes an air collecting hood 5021 installed on the spray tower 1, and an air guide pipe 5022 is installed on the top of the air collecting hood 5021. The air guide pipe 5022 can be designed as a straight pipe as needed. If necessary, a spiral guide plate can be added in the straight pipe to form a spiral ascending flow channel with a small pitch, which slows down the air flow rate and facilitates the mixing and contact of gas and liquid. The impact plate 501 on the same air collecting hood 5021 is kept at the same height to facilitate the unified overflow of the spray liquid collected by the air collecting hood 5021 to form a secondary spray contact. Several impact plates 501 are installed on the air collecting hood 5021, and the air flow guide plate 502 is installed on 1 through a bracket to ensure the stability of the installation. Irregular protrusions can be added to the upper surface of the impact plate 501 to facilitate the dripping spray liquid to collide with the plate surface and disperse into fine water droplets. Several drainage holes are provided on the impact plate 501 to facilitate the passage of gas and liquid through the impact plate 501.

[0022] Reference Figure 2 Several spray heads 403 are installed at the lower end of the coil 401, and a liquid inlet pipe 402 is installed on the coil 401. The liquid inlet pipe 402 is connected to the external spray liquid supply equipment to provide spray liquid to the spray head 403 to ensure sufficient circulation and utilization efficiency of the spray liquid in the tower.

[0023] The implementation principle of the spray structure of a spray tower in the embodiment of the present application is as follows:

[0024] The tail gas enters the lower part of the spray tower 1 through the air inlet 2. Here, the tail gas initially enters the tower and is ready to be sprayed.

[0025] As the exhaust rises, it first encounters the lowest airflow guide plate 502. The variable diameter design of the airflow guide plate 502 reduces the cross-sectional area of ​​the rising airflow, concentrating and accelerating the airflow through the spray liquid area, thereby enhancing the contact between the gas and liquid. Spray liquid is received from an external spray liquid supply via the liquid inlet pipe 402 and evenly sprayed onto the exhaust through the spray head 403. The spray liquid and exhaust gas fully contact within the spray area, and pollutants in the exhaust gas are absorbed or reacted with the spray liquid, achieving the desired purification effect.

[0026] The exhaust gas continues to rise and passes through multiple spray structures separated by the layer 6. In each spray structure, the exhaust gas will undergo a similar spray treatment process until it meets the emission standards.

[0027] After multiple layers of spray treatment, most pollutants in the exhaust gas are removed. The purified exhaust gas exits the spray tower through outlet 3 and enters external exhaust gas treatment equipment for further treatment or direct discharge. The spray liquid containing pollutants is collected and overflowed through overflow pipe 503 and discharged to the lower layer. During the discharge process, it impacts with impact plate 501, causing the dripping spray liquid to impact with the plate surface and disperse into fine droplets.
