Description

Technical Field

[0001] This utility model belongs to the field of demister technology, specifically relating to a curved panel type demister. Background Technology

[0002] A demister is a device used to remove droplets or mist from an airflow. Demisters are defined as devices that remove droplets or mist from an airflow using mechanical separation. When gas containing mist flows through a demister at a certain speed, the mist collides with the corrugated plate due to the inertial impact of the gas and adheres to it, forming larger droplets. When the weight of the droplets exceeds the resultant force of the gas's upward force and the liquid's surface tension, the droplets are separated from the surface of the corrugated plate, thus achieving gas-liquid separation.

[0003] A demister is disclosed in patent application number 201710087779.9. This application uses a transmission roller group to fix the outline of the belt component and transports each surface of the blades to the cleaning device for cleaning, without any cleaning dead corners. Therefore, the bending degree between the blades and the spacing between the blades are not limited in this invention. In conjunction with the above application and compared with the existing demister structure, when the concentration and velocity of the flue gas passing through are different during use, the flue gas will escape from between the panels, thereby affecting the collection efficiency of the device. At the same time, the multi-angled panels will also increase the resistance of the demister, which will also affect the collection effect, thus affecting the practicality of the panel. To address this issue, we propose a curved panel demister. Utility Model Content

[0004] The purpose of this utility model is to provide a curved panel demister to solve the problem mentioned in the background art that, during use, when the concentration and velocity of the flue gas passing through are different, the flue gas will escape from between the panels, thus affecting the collection efficiency of the device. At the same time, the multi-angled panels will also increase the resistance of the demister, which will also affect the collection effect, thus affecting the practicality of the panel.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a curved panel demister, comprising a tower body for mounting a frame, a support frame installed at the bottom of the frame, the support frame being fixed to the inner side of the tower body, a sealing plate installed at the top of the support frame, a through hole at the center of the sealing plate, and two frames symmetrically installed at the through hole, a baffle demister plate and a gradually curved plate being equidistantly arranged on the inner side of the frame, and an integrated sealing plate being provided at both ends of the inner side of the frame.

[0006] Preferably, the deflector plate is provided with an integrated straight plate structure.

[0007] Preferably, the sealing plate is used to block the flue gas, ensuring that the flue gas passes between the spaced-apart baffle demister and the gradually curved plate.

[0009] Preferably, the frame includes a fixed frame and a split frame. The two ends of the frame are provided with fixed seats on the split frame, and the fixed seats are provided with fixed slots. The two ends of the fixed frame are provided with fixed seats, and the inner side of the fixed seats is provided with slots. The fixed frame and the split frame are fitted together by inserting a fixing piece into the slot on the fixed seat.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) By setting the curved panel structure, when the demister in the application is used to remove impurities in the flue gas, the curvature on the panel ensures that the flue gas will not escape without being treated by the demister, thereby improving the collection efficiency. At the same time, the curved structure can also reduce the operating resistance of the flue gas when it passes through, thus better preventing impurities in the flue gas. It can also delay the scaling inside the panel, further improving the practicality of the device.

[0015] (2) In addition, by setting the frame as a split structure, the device can be disassembled and assembled through the fixed frame and split frame structure during use. When using the device, the baffle demisting plate and the gradual curve plate inside the fixed frame and split frame can be fixed through the fixed structure after they are engaged and locked. This makes it convenient to use and disassemble the structure, while improving the convenience and functionality of the device during use. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0024] Example 1

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6This utility model provides a technical solution: a curved panel type demister. During use, mist droplets in the flue gas collide with the demister blades and are captured. The droplets converge to form a water flow, which, due to gravity, falls into a slurry pool, achieving gas-liquid separation. This ensures that the flue gas flowing through the demister meets the demisting requirements before being discharged. This improves operating conditions, optimizes process parameters, reduces equipment corrosion, extends equipment lifespan, increases throughput, recovers valuable materials, protects the environment, and reduces air pollution. The demister includes a tower body 100 for mounting a frame 200. A support frame 103 is installed at the bottom of the frame 200 and fixed to the inside of the tower body 100. A sealing plate 104 is installed at the top of the support frame 103, with a through hole at the center. Two frames 200 are symmetrically installed at the through hole. A spray water pipe 101 is fixedly installed on the inside of the tower body 100 at the bottom of the support frame 103. A water spray nozzle 102 is installed on the water pipe 101 and directly below the frame 200. When the water spray nozzle 102 is working, it can spray water to clean the inner wall of the sealing plate 104, so as to avoid the large amount of impurities on the panel affecting the collection effect during the collection process. The inner side of the frame 200 is provided with baffle demisters 203 and gradient plates 204 at equal intervals. The inner ends of the frame 200 are also provided with integrated sealing plates 206. When the demister in this application is used to collect particles and other objects in the flue gas, the frame 200 is fixed on the support frame 103, and the flue gas can also be blocked by the sealing plate 104 when it passes through, so as to ensure that the flue gas passes through the frame 200 for collection. In addition, when the frame 200 is collecting, the bottom of the support frame 103 can be cleaned by the water spray nozzle 102. When the flue gas passes through, the baffle demisters 203 and gradient plates 204 with a certain curvature set inside the frame 200 can complete the collection of the flue gas.

[0026] Specifically, the deflector plate 203 is equipped with an integrated straight plate structure. By setting an integrated straight plate on the top of the deflector plate 203 for guiding the airflow, it can be used for auxiliary fixation and also guide the airflow. The sealing plate 206 is used to block the flue gas, ensuring that the flue gas passes between the spaced-apart deflector plate 203 and the gradually curved plate 204, thereby improving the collection efficiency. The gradually curved plate 204 is provided with bosses 207 on both sides, and the inner surface of the frame 200 is provided with matching grooves 205 on both sides. The gradually curved plate 204 and the frame 200 are aligned and engaged with the bosses 207 through the matching grooves 205, which facilitates auxiliary installation and improves the convenience of installation.

[0027] Example 2

[0028] Please see Figure 1 , Figure 2 and Figure 3This utility model provides a technical solution: a curved panel demister, wherein the frame 200 includes a fixed frame 201 and a split frame 202. Fixed seats 300 are provided at both ends of the frame 200 on the split frame 202, and fixed slots 302 are provided on the fixed seats 300. Fixed seats 300 are also provided at both ends of the fixed frame 201, and slots are provided on the inner side of the fixed seats 300. The fixed frame 201 and the split frame 202 are engaged by inserting a fixing piece 301 into the slot on the fixed seat 300. During assembly and disassembly, the frame 200 is aligned with the fixed frame 201 and the split frame 202. Simultaneously, both ends of the deflector demister 203 and the gradually curved plate 204 are aligned and engaged with the mating slots 205 on both sides of the frame 200 via protrusions 207, thereby ensuring stable panel installation. While ensuring curvature, when assembling the split frame 202 and the fixed frame 201, it is also necessary to insert and align the fixing piece 301 on the split frame 202 with the fixing seat 300 on the fixed frame 201. After the fixing piece 301 is inserted into the inner side of the fixing seat 300, the screws 304 at both ends of the fixing seat 300 are rotated using a tool. When the screws 304 rotate, they push the fixing block 305 to limit the lifting and lowering within the lifting adjustment groove 303. At the same time, the fixing block 305 contacts the fixing groove 302 on the fixing piece 301 through the inclined surface, thereby fixing the fixing piece 301 in the fixing seat 300 and ensuring the installation stability between the fixed frame 201 and the frame 200. This structure facilitates the disassembly and assembly of the demister and improves the convenience and practicality of the demister during disassembly and assembly.

[0029] Specifically, the fixing base 300 has lifting adjustment slots 303 on both sides of the slot. Screws 304 are also symmetrically installed on both sides of the fixing base 300. The screws 304 adjust the lifting by screwing them in. The screws 304 extend into the lifting adjustment slots 303, and one end of the screws 304 is provided with a fixing block 305 in the lifting adjustment slot 303. The fixing block 305 moves within the lifting adjustment slot 303. The fixing block 305 is provided with an inclined surface corresponding to the fixing slot 302. The fixing block 305 and the fixing base 300 are fixed together by the fixing piece 301 and the fixing base 300, and the fixing piece 301 is fixed by the fixing block 305 against the inclined surface of the fixing slot 302. This is used to fix the fixing piece 301 after insertion, and at the same time ensure the stability between the fixing frame 201 and the split frame 202.
