Description

Technical Field

[0001] This utility model relates to the field of filter element technology for stripping equipment, and in particular to a novel outlet filter element for stripping equipment. Background Technology

[0002] Stripping, also known as stripping desorption, is a highly efficient wastewater treatment process. Its principle involves directly contacting wastewater with steam to transfer volatile toxic and harmful substances from the wastewater into the gas phase, thereby achieving the separation and recovery of pollutants. In the entire stripping system, the gas outlet at the top of the stripping tower is the gas flow channel carrying pollutant components. When this gas flow leaves the tower, it often carries a large number of droplets, mist, and solid impurities. To ensure the stable operation of subsequent process units such as condensation, adsorption, or incineration, and to meet environmental emission requirements, a highly efficient separation and filtration device must be installed at the gas outlet.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: Currently, the traditional filter elements commonly used at the outlet of stripping towers, such as simple metal wire mesh demisters or filter elements made of a single material, mainly rely on the passive interception effect of the filter material. This mechanism is insufficient when facing complex airflows with high humidity and high impurity load.

[0004] To address these issues, we provide a novel outlet filter element for stripping equipment. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of relying too much on the passive filtration of filter media. To address this, we propose a new type of outlet filter element for stripping equipment.

[0006] To achieve the above objectives, this application adopts the following technical solution: a novel stripping equipment outlet filter element, comprising a housing, an mounting block fixedly connected to the bottom of the housing, a rotating groove formed in the inner cavity of the housing, a first support rod fixedly connected to the inner cavity of the housing, a second support rod fixedly connected to the inner cavity of the housing, a third support rod fixedly connected to the bottom of the first support rod, the bottom of the third support rod being fixedly connected to the top of the second support rod, a sleeve provided on the surface of the third support rod, and a rotating blade fixedly connected to the surface of the sleeve.

[0007] Preferably, a first guide plate is fixedly connected to the inner cavity of the outer shell, and a second guide plate is fixedly connected to the inner cavity of the outer shell.

[0008] Preferably, a third guide plate is fixedly connected to the inner cavity of the outer shell, and a first filter block is fixedly connected to the inner cavity of the outer shell.

[0009] Preferably, a second filter block is provided on the surface of the first guide plate, and a third filter block is provided on the surface of the second guide plate.

[0010] Preferably, the bottom of the rotating groove is provided with a flow guide groove, and the inner cavity of the flow guide groove is provided with a flow guide port.

[0011] Preferably, a drain outlet is provided at the bottom of the guide port, which is used to send the separated liquid back to the stripping tower from the inner cavity of the equipment.

[0012] Preferably, an exhaust port is fixedly connected to the top of the housing, and the exhaust port is used to connect to an external collection device.

[0013] The technical effects and advantages of this utility model are as follows: 1. This utility model utilizes a rotary separation structure consisting of a rotating groove, a support rod assembly, and a sleeve with rotating blades. When a droplet-rich airflow enters the device from the bottom, it directly impacts and drives the rotating blades to rotate at high speed. This process converts the kinetic energy of the gas into mechanical energy, generating a powerful centrifugal force without external power. This force actively throws most of the large droplets and solid particles in the airflow toward the inner wall of the outer shell. Compared to traditional filter cartridges that rely solely on passive interception by the filter media, this separation mechanism is more efficient at removing initially high-load impurities. It significantly reduces the burden on the first and second filter blocks at the source, preventing them from being quickly clogged, thereby improving the overall filtration efficiency and extending the service life of the filter cartridge assembly.

[0014] 2. This utility model achieves effective rectification and stepped distribution of airflow through the synergistic effect of the first guide plate, the second guide plate, and the third guide plate, thereby improving the subsequent filtration efficiency and ensuring the stability of the separation process. After the primary separation, the airflow often still has problems with turbulence and uneven energy distribution. These guide plates, as static flow guiding elements, can orderly guide the airflow to the subsequent second and third filter blocks, avoiding airflow short-circuiting or local erosion. By reorganizing the airflow direction and velocity, the guide plates ensure that the airflow can pass through each stage of filter media with a uniform flow rate and coverage area, so that the entire surface of the filter material can be fully utilized, avoiding premature local clogging, thereby maximizing the efficiency of each stage of the filtration structure as a whole.

Detailed Implementation

[0020] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0021] Example 1 Please see Figures 1-4 This utility model is a novel outlet filter element for a stripping equipment, comprising a housing 1, an mounting block 2 fixedly connected to the bottom of the housing 1, a rotating groove 3 opened in the inner cavity of the housing 1, a first support rod 4 fixedly connected to the inner cavity of the housing 1, a second support rod 5 fixedly connected to the inner cavity of the housing 1, a third support rod 6 fixedly connected to the bottom of the first support rod 4, the bottom of the third support rod 6 being fixedly connected to the top of the second support rod 5, a sleeve 7 being provided on the surface of the third support rod 6, and a rotating blade 8 fixedly connected to the surface of the sleeve 7.

[0022] Specifically: Mounting block 2 is used to fix the entire filter element to the outlet pipe of the stripping tower. The first support rod 4, the second support rod 5 and the third support rod 6 together form a stable support frame. The third support rod 6 serves as a rotating shaft. The sleeve 7 is rotatably mounted on the third support rod 6 through a low-friction bushing, so that the rotating blade 8 fixed on its surface can rotate freely under the action of airflow. This structure constitutes the primary dynamic separation structure of the filter element.

[0023] Example 2 Please see Figures 1-4Based on Embodiment 1, a first guide plate 9 is fixedly connected to the inner cavity of the outer shell 1, a second guide plate 10 is fixedly connected to the inner cavity of the outer shell 1, a third guide plate 11 is fixedly connected to the inner cavity of the outer shell 1, a first filter block 12 is fixedly connected to the inner cavity of the outer shell 1, a second filter block 13 is provided on the surface of the first guide plate 9, a third filter block 14 is provided on the surface of the second guide plate 10, a flow channel 15 is provided at the bottom of the rotating groove 3, a flow guide port 16 is provided in the inner cavity of the flow channel 15, a drain port 17 is provided at the bottom of the flow guide port 16, and the drain port 17 is used to send the separated liquid back to the stripping tower from the inner cavity of the equipment, and an exhaust port 18 is fixedly connected to the top of the outer shell 1, and the exhaust port 18 is used to connect to an external collection device.

[0024] Specifically: the first guide plate 9, the second guide plate 10 and the third guide plate 11 are distributed sequentially along the inner cavity of the outer shell 1. The plate panels cover part of the inner cavity of the outer shell 1, leaving a certain gap to allow gas to pass through. They are used to rectify and distribute the airflow after primary separation. The first filter block 12, the second filter block 13 set on the surface of the first guide plate 9 and the third filter block 14 set on the surface of the second guide plate 10 together constitute a static filter structure. Its filtration accuracy can be improved by replacing the filter material. It is used to intercept residual droplets and particulate matter of different particle sizes. The flow channel 15 and the flow port 16 form a continuous liquid collection channel, which guides the liquid that is thrown to the inner wall of the outer shell 1 due to centrifugal force to the drain port 17 at the bottom.

[0025] Working principle: The user installs this filter element on the outlet pipeline of the stripping tower using the mounting block 2. When the humid gas flow rich in droplets and particles enters the inner cavity of the outer shell 1 from the bottom, it first impacts and drives the rotating blade 8 to rotate at high speed, generating a strong centrifugal force that throws most of the large droplets and solid particles toward the inner wall of the outer shell 1, completing dynamic separation. The separated liquid flows down along the inner wall, collects through the guide groove 15 and the guide port 16, and finally returns to the stripping tower through the drain port 17. At the same time, the gas that has undergone primary purification flows upward and passes through the first, second, and third guide plates 11 in sequence. Its flow path is reorganized and evenly distributed. Then it smoothly penetrates the second filter block 13 and the third filter block 14, and finally passes through the first filter block 12. During this process, the residual impurities in the gas are captured step by step by the static filtration structure. Finally, the clean gas is discharged from the exhaust port 18 at the top and enters the downstream condensation or collection device.

[0026] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
