Description

Technical Field

[0001] This utility model relates to the field of spray tower exhaust gas treatment technology, and in particular to a double-row blade air inlet distributor. Background Technology

[0002] In the process of treating organic waste gas using spray absorption towers, the commonly used method is to directly send the waste gas into the absorption tower using a fan. However, this traditional air intake method has many shortcomings that urgently need to be addressed:

[0003] First, the uneven distribution of waste gas during its ascent within the tower prevents the tower packing material from being fully utilized, resulting in a large amount of packing material operating in an inefficient state. This severely affects the purification efficiency of the organic waste gas, making it difficult for the treated waste gas to meet the ideal emission standards.

[0004] Secondly, excessive wind pressure in localized areas can easily cause deformation or even disintegration of the packing material inside the tower. This not only requires frequent replacement of the packing material, increasing equipment maintenance costs and downtime, but may also lead to unstable exhaust gas treatment performance due to packing damage.

[0005] Furthermore, when the exhaust gas enters the tower, it directly impacts the inner wall of the tower, which generates significant resistance. This not only increases the energy consumption of the fan but may also affect the stable operation of the entire exhaust gas treatment system due to resistance fluctuations.

[0006] To address the aforementioned issues, the development of an air inlet distribution device capable of achieving uniform distribution of exhaust gas, reducing local wind pressure, and minimizing airflow resistance has become an urgent need in the field of organic waste gas treatment using spray absorption towers. This double-row blade air inlet distributor is proposed based on this background. Utility Model Content

[0007] To address the technical problems existing in the background art, this utility model proposes a double-row blade air intake distributor.

[0008] This utility model proposes a double-row blade air inlet distributor, including a spray tower. The bottom of the spray tower is provided with an exhaust gas inlet. Inside the spray tower, a distributor corresponding to the exhaust gas inlet is fixed. The distributor includes two rows of symmetrically arranged blades. The airflow entering through the exhaust gas inlet is diverted to each blade.

[0009] Furthermore, the distributor also includes a base plate and a cover plate fixed inside the spray tower, with two rows of blades fixed between the base plate and the cover plate.

[0010] Furthermore, the bottom plate and the cover plate are identical in shape and size, and both ends are configured with arc-shaped structures that are adapted to the inner wall of the spray tower.

[0011] Furthermore, both the base plate and the cover plate are configured as fan-shaped structures with the front end dimension larger than the rear end dimension.

[0012] Furthermore, each blade is configured with an "L"-shaped structure, and the corners are configured with arc-shaped flow guide structures.

[0013] Furthermore, a diversion inlet and a diversion outlet are reserved between two longitudinally adjacent blades to facilitate airflow diversion.

[0014] Furthermore, the distance between two horizontally adjacent blades gradually decreases.

[0015] The beneficial effects of this invention are: it can significantly improve the distribution of waste gas in the spray tower. Through the diversion and guidance of two rows of symmetrical blades, the airflow entering from the waste gas inlet is evenly distributed to each blade. The airflow flows in an orderly manner through the diversion inlet and outlet between adjacent blades in the longitudinal direction, and the design of gradually decreasing spacing between adjacent blades in the transverse direction further optimizes the airflow distribution. This effectively solves the problem of uneven waste gas distribution in traditional air intake methods, greatly improves the utilization efficiency of the packing material in the tower, and allows the packing material to fully contact the waste gas in a wider area, thereby improving the purification effect of organic waste gas and reducing the risk of excessive waste gas emissions.

[0021] Reference Figure 1-4 This utility model proposes a double-row blade air inlet distributor, mainly used in the exhaust gas treatment system of a spray tower, aiming to achieve uniform distribution of exhaust gas and improve the spray purification effect. The specific technical solution is as follows:

[0022] The double-row blade air inlet distributor includes a spray tower 1, which serves as the main equipment for waste gas treatment. The spray tower 1 forms a space for waste gas purification inside. The specific structure of the spray tower 1 and the principle of purifying waste gas through spraying are well-known technical contents to those skilled in the art and will not be detailed here. A waste gas inlet 2 is reserved at the bottom of the spray tower 1, through which the waste gas enters the interior of the spray tower 1.

[0023] To achieve effective diversion and distribution of exhaust gas, a distributor 3 corresponding to the exhaust gas inlet 2 is fixed inside the spray tower 1. The distributor 3 is the core component for achieving uniform distribution of exhaust gas. It includes two rows of symmetrically arranged blades 33. The airflow entering from the exhaust gas inlet 2 is diverted to each blade 33, and the airflow is guided and distributed through the action of the blades 33. The distributor 3 also includes a base plate 31 and a cover plate 32 fixed inside the spray tower 1. The two rows of blades 33 are fixed between the base plate 31 and the cover plate 32. The base plate 31 and the cover plate 32 fix and support the blades 33, ensuring that the blades 33 are in operation. Stability during the process; The bottom plate 31 and the cover plate 32 are identical in shape and size, and both ends are set as arc-shaped structures that fit the inner wall of the spray tower 1. This arc-shaped structure allows the bottom plate 31 and the cover plate 32 to fit tightly against the inner wall of the spray tower 1, which not only enhances the stability of the connection, but also avoids the leakage of exhaust gas in the gaps, ensuring the efficiency of exhaust gas treatment. At the same time, the bottom plate 31 and the cover plate 32 are both set as fan-shaped structures with the front end size larger than the end end size. The front end is close to the exhaust gas inlet 2. This structural design is conducive to better receiving the exhaust gas entering from the exhaust gas inlet 2 and provides reasonable space for the diversion of exhaust gas.

[0024] In addition, each blade 33 is designed with an "L" shape and a circular arc guide structure at the corner. The "L" shape can change the direction of exhaust gas flow, while the circular arc guide structure can reduce the airflow resistance at the corner, reduce energy loss, and make the airflow flow more smoothly.

[0025] In the arrangement of the blades 33, a diversion inlet and a diversion outlet are reserved between two longitudinally adjacent blades 33 to facilitate the diversion of airflow. When the exhaust gas enters the distributor 3, it will enter the space between the adjacent blades 33 through these diversion inlets and then flow out from the diversion outlet, thus realizing the initial diversion of exhaust gas. In addition, the spacing between two laterally adjacent blades 33 gradually decreases. This design allows the airflow to be gradually compressed during the lateral flow, further promoting the uniform distribution of airflow and avoiding the situation where the local airflow is too concentrated.

[0026] The working process of this double-row blade air inlet distributor is as follows: Exhaust gas enters from the exhaust gas inlet 2 at the bottom of the spray tower 1. Since the distributor 3 corresponds to the exhaust gas inlet 2, the exhaust gas first contacts the distributor 3. Under the action of the distributor 3, the exhaust gas is diverted to two rows of blades 33. The diversion inlet between longitudinally adjacent blades 33 allows the exhaust gas to enter. After being guided by the blades 33, the exhaust gas flows out from the diversion outlet and then flows towards the top outlet of the spray tower 1 (this process is shown in the attached diagram). Figure 3 , 4 As shown in the figure, the design of gradually decreasing spacing between adjacent blades 33 in the lateral direction further homogenizes the airflow during lateral flow. The exhaust gas treated by the distributor 3 is evenly distributed in the spray tower 1 and comes into full contact with the liquid sprayed by the spray system, thereby improving the purification efficiency of the exhaust gas.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
