Description

Technical Field

[0001] The utility model relates to a partitioned scrubber, belonging to the technical field of waste gas treatment equipment. Background Art

[0002] A scrubber, also known as a wet scrubber, is a device commonly used for industrial waste gas treatment. It mainly removes pollutants in the waste gas through the contact between a liquid (usually water or a chemical solution) and the gas. Currently, the scrubber mainly sprays water in the device to wash the gas, and the washed gas is directly discharged from the position of the demisting layer above. However, when using a device in this way, the air outlet is located above the device, which is not conducive to manual regulation and maintenance. In addition, the air resistance above the device is relatively large, which is likely to affect the actual air outlet efficiency at the air outlet position. The direct discharge of the gas from above the demisting layer will also result in a relatively high water content in the discharged gas, which will bring many inconveniences to the use of the device. Summary of the Invention

[0003] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a partitioned scrubber, which is used to solve the many defects caused by the traditional scrubber exhausting air from above, and can be beneficial to improving the air outlet effect, enhancing the drying effect of the gas, and facilitating manual maintenance operations.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A partitioned scrubber provided by the utility model includes a tower body. A partition is arranged inside the tower body. The partition extends from the lower part of the tower body to the upper part of the tower body and does not form a closed contact with the top surface of the tower body. The partition is used to divide the interior of the tower body into a waste gas treatment chamber and a purified gas discharge chamber. Inside the waste gas treatment chamber, a packing layer, a spraying mechanism, and a demisting layer are respectively arranged from bottom to top. An air inlet pipe is arranged on the tower body and is connected to the waste gas treatment chamber and is located below the packing layer. A first exhaust pipe is arranged at the bottom position of the tower body and is connected to the purified gas discharge chamber.

[0006] Specifically, it further includes a reflux pump. A water tank is connected and arranged at the bottom of the waste gas treatment chamber. The reflux pump is connected to the water tank and is used to supply the liquid in the water tank to the spraying mechanism.

[0007] Specifically, it further includes a fan. The fan is connected and arranged with the first exhaust pipe, and a second exhaust pipe is arranged at the air outlet of the fan.

[0008] Specifically, taking the horizontal plane as the cross-section, the ratio of the cross-sectional area of the waste gas treatment chamber to the cross-sectional area of the purified gas discharge chamber is 2:1 to 6:1.

[0009] Specifically, the number of the first exhaust pipes is not less than two, and an air chamber is communicated at the air inlet position of the fan. The air chamber is used to communicate with all the first exhaust pipes simultaneously.

[0010] Specifically, the number of the first exhaust pipes is not less than two, and the number of the fans is not less than two. One of the fans is used to communicate with all the first exhaust pipes when other fans fail.

[0011] Specifically, a detection platform is further installed at the top of the tower body. A guardrail is arranged on the periphery of the detection platform, and the detection platform is connected to the ground through a ladder.

[0012] Specifically, a packing layer support plate is fixedly installed inside the tower body. The tower body is composed of not less than two splicing bodies spliced together, and the packing layer support plate is installed above the splicing body located at the lower part.

[0013] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows:

[0014] In the present utility model, the inside of the tower body is divided into a gas treatment chamber and a purified gas discharge chamber by a partition plate, so that the treated gas can be discharged from the lower part of the scrubber. Since the air outlet is located at the lower part, it is convenient for manual operation connection or maintenance. In addition, the exhaust at the bottom position can reduce the pressure drop of the gas, which is convenient for gas discharge. After the treated gas passes through the gas discharge chamber and then is discharged, the travel distance of the gas discharge can be increased, and the water vapor is easily condensed inside the tower body, which is beneficial to reducing the moisture carried by the gas and can reduce the dependence on the demister, thereby improving the drying effect of the gas.

[0023] Embodiment:

[0024] A partitioned scrubbing tower provided by an embodiment of the present utility model is used to solve many defects caused by the traditional scrubbing tower exhausting air from above, which is beneficial to improving the air outlet effect, improving the drying effect of the gas, and facilitating manual maintenance and inspection operations. To achieve the above functions, the equipment is provided with a tower body 1. Specifically, a partition board 2 is arranged inside the tower body 1, as Figure 3As shown in the figure, the partition plate 2 extends from the lower part to the upper part of the tower body 1 and does not form a closed contact with the top surface of the tower body 1. The partition plate 2 is used to divide the interior of the tower body 1 into an exhaust gas treatment chamber and a purified gas discharge chamber. Among them, a packing layer 3, a spraying mechanism 4, and a demisting layer 5 are respectively arranged in the exhaust gas treatment chamber from bottom to top. An air inlet pipe port 6 is arranged on the tower body 1 and is connected to the exhaust gas treatment chamber and is located below the packing layer 3. A first exhaust pipe 7 communicating with the purified gas discharge chamber is arranged at the bottom position of the tower body 1. Through this setting method, after the gas enters at the position of the air inlet pipe port 6, the gas travels upward from the packing layer 3 and undergoes spraying and demisting effects, continues to move into the purified gas discharge chamber, and finally is discharged from the first exhaust pipe 7 at the bottom position of the chamber. In this way, when the gas is discharged, due to the small wind resistance at the air outlet position, the pressure drop is reduced, so that the gas can be efficiently discharged. However, after the gas passes through the demisting layer 5, it will still stay in the tower body 1 for a relatively long time. Therefore, the gas is easily affected by the condensation effect and the moisture contained in it can be further reduced. The design with the exhaust port located below enables the operator to timely observe the exhaust state at the exhaust port position for treatment or maintenance, which is more convenient for manual operation and use. The floor area of this new type of exhaust gas washing system is about 1 / 2 to 1 / 3 of that of the traditional washing system; the total cost of the new type of exhaust gas washing system is about 70% to 90% of that of the traditional washing system; the installation period of the new type of exhaust gas washing is about 1 / 2 to 1 / 3 of that of the traditional washing system; the gas flow rate of the new type of exhaust gas washing is 1 to 1.5 times that of the traditional washing system; the pressure loss of the new type of exhaust gas washing is 70% to 90% of that of the traditional washing system; the acid gas removal efficiency of the new type of exhaust gas washing is 10% to 40% higher than that of the traditional washing system.

[0025] A partitioned washing tower provided by an embodiment of the present invention. In order to improve the ability to reuse the washing liquid, the device further includes a reflux pump 8. At this time, a water tank 9 is connected and arranged at the bottom of the exhaust gas treatment chamber. The liquid after spraying and washing can flow back into the water tank 9. At this time, by connecting the reflux pump 8 to the water tank 9 and using it to supply the liquid in the water tank 9 to the position of the spraying mechanism 4, the effect of saving liquid usage can be achieved, which is beneficial to saving resources.

[0026] A partitioned washing tower provided by an embodiment of the present invention. In order to further improve the stable air outlet effect, the device further includes a fan 10. At this time, the fan 10 is connected to the first exhaust pipe 7, and a second exhaust pipe 11 is arranged at the air outlet of the fan 10, which can realize the rapid drainage of the gas in the tower body 1 and ensure that the air outlet efficiency can be improved.

[0027] A partitioned scrubber provided by an embodiment of the present utility model has a horizontal plane as the cross-section, and the ratio of the cross-sectional areas of the waste treatment chamber and the purified gas discharge chamber is 2:1 to 6:1. Controlling the ratio within this reasonable range can keep the air outlet efficiency of the scrubbing area in a certain matching degree with the actual air outlet rate, ensuring the maximum rational utilization of space within a reasonable range.

[0028] A partitioned scrubber provided by an embodiment of the present utility model. Considering that the purified gas discharge chamber may be set too narrow in some embodiments, the connection diameter of the first exhaust pipe 7 may be too small when connected. Therefore, it is preferred that the number of the first exhaust pipes 7 is not less than two. To simplify the connection steps, an air chamber 12 may be connected and provided at the air inlet position of the fan 10. The air chamber 12 is used to connect all the first exhaust pipes 7 simultaneously, as Figure 1 shown. In some other embodiments, the number of the first exhaust pipes 7 may also be set to be not less than two. At this time, the number of the fans 10 is not less than two. One of the fans 10 is used to connect all the first exhaust pipes 7 when other fans 10 fail, and the fans 10 for working can connect all or connect the corresponding first exhaust pipes 7 separately.

[0029] A partitioned scrubber provided by an embodiment of the present utility model. To facilitate maintenance and inspection at the top of the tower body 1, since the air outlet is no longer located at the top of the tower, a detection platform 13 may be further installed at the top of the tower body 1. A guardrail is provided on the periphery of the detection platform 13. The detection platform 13 is connected to the ground through a ladder, which can facilitate the operator to climb to the top of the equipment to perform maintenance and inspection on the equipment.

[0030] A partitioned scrubber provided by an embodiment of the present utility model. Considering that the packing layer 3 inside the special-shaped tower body 1 is not easy to install, a packing layer support plate 14 may be fixedly installed inside the tower body 1. The tower body 1 is composed of not less than two splicing bodies spliced together, and the packing layer support plate 14 is arranged above the splicing body located at the lower part. The installation of the packing layer 3 can be completed first and then the splicing of the tower body 1 can be completed before splicing the tower body 1.

[0031] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present utility model.
