Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of waste gas treatment equipment, and in particular to a circular screen ventilation tower. Background Technology
[0002] In the field of industrial waste gas treatment, the sieve-type waste gas treatment water tower is a common purification device. Its core function is to guide waste gas through ducts to achieve gas-liquid contact with the spray liquid, thereby achieving the adsorption and neutralization of pollutants. However, existing sieve-type water towers generally adopt a square tower structure, with the internal ducts and spray areas usually concentrated in the same longitudinal space. This easily leads to uneven flow field distribution within the water tower. The geometric characteristics of the square tower make it easy for eddies and short-circuiting phenomena to occur during the flow of waste gas. Some waste gas is discharged directly without sufficient spray treatment, reducing the gas-liquid contact efficiency. Because the ducts and spray areas overlap longitudinally, the waste gas must rise slowly along a fixed path, limiting the countercurrent contact time with the spray liquid, making it difficult to increase the treatment capacity per unit time. To compensate for the insufficient efficiency, existing technologies often enhance the treatment effect by increasing the tower size or the spray volume, but this significantly increases the equipment footprint and operating energy consumption. Therefore, there is an urgent need for a sieve-type water tower with a more efficient duct structure and water tower structure, which can effectively shorten the waste gas spray treatment cycle, improve the treatment efficiency of the water tower, and save costs. Utility Model Content
[0003] The purpose of this invention is to provide a circular screen air tower to solve the problem of low treatment efficiency of existing square screen air exhaust gas treatment towers.
[0004] The present invention provides the following technical solution: a circular screen water tower, comprising a tower body, a water system, and an air duct system. The tower body is cylindrical, and a spray pump is connected to the outer side of the tower body. A spray chamber is provided on the inner side of the tower body. A first horizontal plate and a second horizontal plate are arranged along the height direction in the spray chamber. The output end of the spray pump is located on one side above the first horizontal plate. The water system includes drainage holes on the first and second horizontal plates, forming a longitudinal water treatment zone in the spray chamber. The air duct system includes a first air inlet and a second air inlet. The first air inlet is located on the side of the first horizontal plate away from the output end of the spray pump, and the second air inlet is located on the side of the second horizontal plate away from the first air inlet, forming an "S"-shaped waste gas flow channel in the spray chamber. The water treatment zone extends longitudinally through the waste gas flow channel.
[0005] As described above, a circular screen water tower is provided with a demisting chamber on the inner side of the tower body, and the demisting chamber is located above the spray chamber.
[0006] As described above, in a circular sieve water tower, a partition is provided between the demisting chamber and the spraying chamber, and an exhaust port communicating with the outside is provided on the upper side of the demisting chamber.
[0007] As described above, in a circular sieve water tower, the spray chamber is further provided with multiple longitudinal baffles. The longitudinal baffles are connected to the edge of the first horizontal plate near the first air inlet to narrow the channel between the first air inlet and the lower side space of the first horizontal plate.
[0008] In a circular sieve water tower as described above, the longitudinal partition is connected to the edge of the second horizontal plate near the second air inlet to narrow the channel between the second air inlet and the lower space of the second horizontal plate.
[0009] As described above, in a circular screen water tower, a longitudinal baffle is provided on the side of the output end of the spray water pump to narrow the channel between the output end of the spray water pump and the waste gas flow channel.
[0010] As described above, in a circular sieve water tower, the upper side of the longitudinal partition is provided with a water-proof edge, and the height of the water-proof edge is higher than the upper surface of the first horizontal plate or the second horizontal plate.
[0011] As described above, in a circular screen water tower, the spray chamber has a water storage area on the lower side of the second horizontal plate, and the spray water pump extends into the water storage area.
[0012] As described above, a circular sieve water tower has an air inlet in its main body that communicates with the outside. The air inlet is located on the side wall of the demisting chamber away from the second air inlet, and the air inlet is located on the lower side of the second horizontal plate.
[0013] Compared with the prior art, the present invention has the following advantages:
[0014] 1. The circular screen-air water tower of this utility model adopts a cylindrical shape, which makes the inner wall of the tower uniformly stressed when the external fan extracts the gas inside the tower, reducing the possibility of tower deformation. At the same time, the combination of water and air duct mechanisms creates a longitudinal water treatment zone and an "S"-shaped waste gas flow channel in the spray chamber. After entering the spray chamber, the waste gas must pass through the waste gas flow channel before it can be discharged. During this process, the spray water in the water treatment zone is sprayed out, drips from the first horizontal plate to the second horizontal plate through the drainage holes, and then drips from the second horizontal plate through the drainage holes again. This process allows for full contact with the waste gas, greatly improving the spray treatment effect of the tower and significantly enhancing the treatment efficiency of the screen-air water tower.
[0015] 2. The circular screen water tower of this utility model has a demisting chamber set on the upper side of the spray chamber inside the water tower body, which can be used to place demisting balls, etc., effectively reducing the water mist attached to the exhaust gas when it is discharged, and facilitating the subsequent treatment of the discharged exhaust gas.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1: Please refer to the appendix Figure 1 To be continued Figure 3This embodiment provides a circular sieve water tower, including a tower body 1, a water system 2, and an air duct system 3. The tower body 1 is cylindrical, and a spray pump 11 is connected to the outer side of the tower body 1. A spray chamber 12 is provided on the inner side of the tower body 1. A first horizontal plate 121 and a second horizontal plate 122 are arranged along the height direction in the spray chamber 12. The output end of the spray pump 11 is located on one side above the first horizontal plate 121. The water system 2 includes components disposed on the first horizontal plate 121 and the second horizontal plate 122. The drainage holes 21 on the two horizontal plates 122 form a longitudinal water treatment zone 22 in the spray chamber 12. The air duct mechanism 3 includes a first air inlet 31 and a second air inlet 32. The first air inlet 31 is opened on the side of the first horizontal plate 121 away from the output end of the spray water pump 11, and the second air inlet 32 is opened on the side of the second horizontal plate 122 away from the first air inlet 31, so that an "S"-shaped waste air flow channel 33 is formed in the spray chamber 12. The water treatment zone 22 runs through the waste air flow channel 33 longitudinally. The circular screen-air water tower of this embodiment adopts a cylindrical shape for the tower body 1, which makes the inner wall of the tower body uniformly stressed when the external fan extracts the gas inside the tower body 1, reducing the possibility of tower deformation. At the same time, the water channel mechanism 2 and the air duct mechanism 3 are used in combination, so that the spray chamber 12 forms a longitudinal water treatment zone 22 and an "S"-shaped waste gas flow channel 33 respectively. After the waste gas enters the spray chamber 12, it must completely pass through the waste gas flow channel 33 before it can be discharged. During this period, the spray water in the water treatment zone 22 is sprayed out, drips from the first horizontal plate 121 to the second horizontal plate 122 through the drainage hole 21, and then drips from the second horizontal plate 122 through the drainage hole 21. During this process, it can fully contact the waste gas, which greatly improves the spray treatment effect of the tower body on the waste gas and greatly improves the treatment efficiency of the screen-air water tower.
[0022] The water tower body 1 is also provided with a demisting chamber 13 on the inner side, which is located above the spray chamber 12. The demisting chamber 13 is provided above the spray chamber 12 inside the water tower body 1, which can be used to place demisting balls, etc., effectively reducing the water mist attached to the exhaust gas when it is discharged, and facilitating the subsequent treatment of the discharged exhaust gas.
[0023] Preferably, a partition net 14 is provided between the demister chamber 13 and the spray chamber 12. The partition net 14 can support demister balls while ensuring the passage of exhaust gas. An exhaust port 15 connected to the outside is provided on the upper side of the demister chamber 13.
[0024] The spray chamber 12 is also equipped with multiple longitudinal baffles 16. The longitudinal baffles 16 are connected to the edge of the first horizontal plate 121 near the first air inlet 31, narrowing the channel between the first air inlet 31 and the lower space of the first horizontal plate 121. The longitudinal baffles 16 are also connected to the edge of the second horizontal plate 122 near the second air inlet 32, narrowing the channel between the second air inlet 32 and the lower space of the second horizontal plate 121. The longitudinal baffles 16 can effectively block the exhaust gas as it passes through the exhaust gas flow channel 33, thereby ensuring more thorough contact between the exhaust gas and the spray water and improving the spray treatment effect of the spray chamber 12.
[0025] A longitudinal baffle 16 is provided on the side of the output end of the spray water pump 11 to narrow the channel between the output end of the spray water pump 11 and the waste gas channel 33, so as to ensure that the spray water can flow smoothly onto the surface of the first horizontal plate 121 after being sprayed out from the output end of the spray water pump 11.
[0026] The upper side of the longitudinal partition 16 is provided with a water-proof edge 161, the height of which is higher than the upper surface of the first horizontal plate 121 or the second horizontal plate 122. The water-proof edge 161 can effectively block the water flow and prevent the spray water from flowing directly down from the first air port 31 or the second air port 32, ensuring that the spray water can flow completely within the water treatment zone 22.
[0027] The spray chamber 12 has a water storage area 123 on the lower side of the second horizontal plate 122, and the spray water pump 11 extends into the water storage area 123. The spray water pump 11 can draw spray water from the water storage area 123 for circulating spraying.
[0028] The water tower body 1 has an air inlet 17 that connects to the outside. The air inlet 17 is located on the side wall of the demisting chamber 17 away from the second air inlet 32, and the air inlet 17 is located on the lower side of the second horizontal plate 122. After the exhaust gas enters the demisting chamber 17 from the air inlet 17, it flows completely through the exhaust gas passage 33, then enters the demisting chamber 13, and finally is extracted from the water tower body from the exhaust port 15.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
