Description

Technical Field

[0001] This utility model relates to the field of flue gas treatment technology, and in particular to a desulfurization and denitrification combined dust removal flue gas filtration device. Background Technology

[0002] With the acceleration of industrialization and urbanization, the emissions of waste gas from numerous factories, power plants, and processing plants have become a serious environmental problem. Among them, harmful gases such as sulfur dioxide and nitrogen oxides produced by fuel combustion have caused severe pollution to the atmosphere and ecological environment, exacerbating problems such as acid rain and particulate matter. Therefore, controlling the emission of these harmful gases has become an urgent need.

[0003] Desulfurization and denitrification typically involve chemical reactions, requiring thorough mixing of the desulfurizing or denitrifying agent with the flue gas for effective removal. Existing systems without rotating spray structures may not be able to evenly and comprehensively spray the desulfurizing or denitrifying agent or cleaning agent into the flue gas to promote pollutant removal and filter media cleaning, thus failing to achieve optimal removal efficiency and reducing treatment effectiveness. This leads to pollutant accumulation and clogging on the filter media surface, affecting its ventilation and dust removal efficiency. This may increase the frequency of maintenance and cleaning, reducing system stability and reliability. After prolonged use, a large amount of material remains on the filter plates. The lack of quick-release mechanisms makes cleaning, replacement, or maintenance of the filters more difficult, increasing maintenance complexity and potentially extending downtime. This could impact the production efficiency of the plant or industrial production line, increasing equipment load and the risk of damage. This could result in costly repairs and significant downtime. Utility Model Content

[0004] The main objective of this invention is to provide a desulfurization, denitrification, and dust removal flue gas filtration device that effectively addresses the problem of reduced treatment efficiency, leading to pollutant accumulation and clogging on the filter media surface, affecting its ventilation and dust removal performance. This can increase the frequency of maintenance and cleaning, reduce system stability and reliability, and impact the production efficiency of factories or industrial production lines, increasing equipment load and thus the risk of equipment damage. This can result in costly repairs and downtime.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a desulfurization and denitrification combined dust removal flue gas filtration device, comprising a body, wherein a rotating spray structure is provided inside the body;

[0006] The rotating spray structure includes: a water tank, two water pumps, and two first support rings. The left side wall of the water tank is fixedly connected to the right side of the machine body. A support plate is fixedly connected to the inner left side wall of the water tank. The bottom wall of the water pump is fixedly connected to the upper side wall of the support plate. The input end of the water pump is connected to a water inlet, and the output end of the water pump is connected to a first delivery pipe. The outer sides of the top ends of the first delivery pipes are connected to connecting pipes. The other ends of the two connecting pipes are connected through the interior of the first support rings. The outer sides of the two connecting pipes are connected to spray pipes. Multiple spray pipes... Both ends of the spray pipe are fixedly connected to the inner wall of the first support ring. The bottoms of the multiple spray pipes are all connected to internally threaded pipes. The bottom ends of the multiple internally threaded pipes are internally threaded to externally threaded pipes. The interiors of the multiple externally threaded pipes are provided with second conveying pipes. The top outer sides of the multiple second conveying pipes are fixedly connected to first connecting rings. The bottom ends of the multiple first connecting rings are located at the top ends of the externally threaded pipes. The bottom interior of the second conveying pipes is fixedly connected to atomizing nozzles. The bottom left side of the water tank is connected to a connecting pipe. The other end of the connecting pipe is connected to the bottom of the machine body.

[0007] Furthermore, a feed pipe is connected to the bottom left side of the machine body, and a discharge pipe is connected to the top of the machine body. A sedimentation tank is provided inside the machine body, and the left end of the connecting pipe is connected through the interior of the sedimentation tank.

[0008] Furthermore, each of the two machine bodies is fixedly connected to a second support ring, and each of the two second support rings is provided with a second connecting ring on its upper sidewall. Each of the two second connecting rings is fixedly connected to a fixed plate, and each of the two fixed plates is fixedly connected to a filter plate.

[0009] Furthermore, two outer shells are fixedly connected to the left and right sides of the two second connecting rings. Each outer shell has a bracket slidably connected to its front and rear sides. Each bracket has four first springs fixedly connected to its rear sidewall. The other end of each first spring is fixedly connected to the front and rear sides of the outer shell.

[0010] Furthermore, each of the outer casings has four second springs fixedly connected in its internal slot, and the bottom of each of the four second springs has two baffles fixedly connected.

[0011] Furthermore, two fixing blocks are fixedly connected to the inside of the left and right sides of the two second support rings, and two first locking blocks are fixedly connected to the top of each fixing block. The first locking blocks are configured to correspond to the locking slots inside the outer shell.

[0012] Furthermore, two second locking blocks are fixedly connected to the front and rear sides of the bottom wall of the two second connecting rings, and two slots are opened on the front and rear sides of the two second support rings, with multiple second locking blocks and slots correspondingly arranged.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model, through its rotating spray structure, can solve the problem of reduced treatment effect, resulting in the accumulation and clogging of pollutants on the surface of the filter medium, affecting its ventilation and dust removal effect. This may increase the frequency of maintenance and cleaning, and reduce the stability and reliability of the system. An external pipe connects to the water tank to add denitrifying agent or cleaning agent and clean water. The water pump's inlet draws the denitrifying agent or cleaning agent and clean water from the tank, and the first delivery pipe at the pump's output delivers the water to a connecting pipe that flows into multiple spray pipes. Before spraying, the denitrifying agent or cleaning agent and clean water flow into a second delivery pipe through an internally threaded pipe connected to an externally threaded pipe at the bottom of the spray pipe. The water is then sprayed through atomizing nozzles. The pressure of the water flow drives the atomizing nozzles to rotate, causing the entire second delivery pipe and the first connecting ring at the top of the second delivery pipe to rotate on the top of the externally threaded pipe, achieving a rotating spray effect. This effectively improves treatment efficiency, system stability, and maintenance costs, and ensures comprehensive and uniform coverage of the internal flue gas during spray filtration.

[0015] 2. By incorporating brackets, first springs, second springs, baffles, and fixing blocks, this system effectively addresses issues that could negatively impact production efficiency in factories or industrial production lines, increase equipment load, and thus raise the risk of equipment damage. This can lead to costly repairs and downtime. By pressing the brackets on the front and rear sides of the housing and sliding them back and forth within the housing, the four first springs inside the housing are compressed. This pushes the second connecting ring on the outer side of the housing onto the upper side wall of the second support ring. Simultaneously, the first locking blocks on the fixing blocks inside the second support ring engage with the slots inside the housing. Releasing the brackets causes them to spring back, and the bottom of the brackets inserts into the holes inside the first locking blocks for secure fixation. This effectively reduces maintenance time and risk, improving system reliability and efficiency.

[0016] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] like Figure 1 - Figure 7 As shown: A desulfurization and denitrification combined dust removal flue gas filtration device includes a body 1, and a rotating spray structure 2 is provided inside the body 1;

[0031] The rotary spray structure 2 includes: a water tank 201, two water pumps 203, and two first support rings 207. The left side wall of the water tank 201 is fixedly connected to the right side of the body 1. A support plate 202 is fixedly connected to the inner left side wall of the water tank 201. The bottom wall of the water pump 203 is fixedly connected to the upper side wall of the support plate 202. The support plate 202 supports and fixes the water pump 203. The input end of the water pump 203 is connected to a water inlet 204, and the output end of the water pump 203 is connected to a first delivery pipe 205. The input end of the water pump 203 draws in the cleaning agent and clean water inside the water tank 201, and the first delivery pipe 205 at the output end transmits them to the next device. The top outer sides of the feed pipe 205 are connected to connecting pipes 206. The other ends of the two connecting pipes 206 are connected through the inside of the first support ring 207. By fixing the connecting pipes 206 inside the first support ring 207, the connecting pipes 206 are supported and fixed. The first support ring 207 is fixed inside the body 1 to spray the flue gas inside the filter device and the body 1. The outer sides of the two connecting pipes 206 are connected to spray pipes 208. Water and other substances are evenly distributed to the inside of the multiple spray pipes 208 through the inside of the connecting pipes 206. The front and rear ends of the multiple spray pipes 208 are fixed to the inner wall of the first support ring 207. The bottom of each spray pipe 208 is connected to an internally threaded pipe 209. The bottom ends of multiple internally threaded pipes 209 are internally threaded to externally threaded pipes 210. The externally threaded pipes 210 connect to the internally threaded pipes 209, and their tops support the internal second conveying pipes 211. Each of the multiple externally threaded pipes 210 contains a second conveying pipe 211. The top outer side of each of the multiple second conveying pipes 211 is fixedly connected to a first connecting ring 212. The bottom ends of the multiple first connecting rings 212 are located at the top of the externally threaded pipes 210. An atomizing nozzle 213 is fixedly connected to the bottom of the internal side of the second conveying pipe 211. When sprayed through the atomizing nozzle 213, the spray... The water is sprayed from the upper slot. When spraying water, the water pressure drives the atomizing nozzle 213 to rotate. The rotating atomizing nozzle 213 connects to the inside of the second delivery pipe 211 and drives the first connecting ring 212 on the top of the second delivery pipe 211 to rotate on the top of the external threaded pipe 210, thereby achieving the effect of rotating spraying to evenly cover the inside of the machine body 1. A connecting pipe 214 is connected through the bottom left side of the water tank 201. The other end of the connecting pipe 214 is connected through the bottom of the machine body 1. The cleaning agent and clean water flowing into the bottom of the machine body 1 are returned to the inside of the water tank 201 through the connecting pipe 214 for reuse, thereby achieving the effect of recycling.

[0032] like Figure 1- Figure 8 As shown, a feed pipe 3 is connected to the bottom left side of the machine body 1. The feed pipe 3 is connected to an external pipe to transfer flue gas into the machine body 1 for treatment. A discharge pipe 4 is connected to the top of the machine body 1 to discharge the filtered flue gas. A sedimentation tank 5 is provided inside the machine body 1 to settle the filtered impurities and particulate matter. The left end of the connecting pipe 214 is connected to the inside of the sedimentation tank 5. A second support ring 6 is fixedly connected inside the machine body 1. A second connecting ring 7 is provided on the upper side wall of each of the two second support rings 6. The second support rings 6 are used to connect and support the second connecting rings 7. A fixed plate 8 is fixedly connected inside each of the two second connecting rings 7. A filter plate 9 is fixedly connected inside each of the two fixed plates 8. The second connecting rings 7 are used to connect to the fixed plates 8 inside the machine body 1 and to support and fix the fixed plates 8.

[0033] like Figure 1 - Figure 10 As shown, two outer shells 10 are fixedly connected to the left and right sides of each of the two second connecting rings 7. Each outer shell 10 has a bracket 11 slidably connected to its front and rear sides. The brackets 11 slide within the outer shell 10, driving the internal device to operate. Four first springs 12 are fixedly connected to the rear side wall of the other side of each bracket 11. These first springs 12 are fixed inside the outer shell 10 to achieve a springback reset effect. The other end of each first spring 12 is fixedly connected to the front and rear sides inside the outer shell 10. Four second springs 13 are fixedly connected to the internal slots of the shell 10. Two baffles 14 are fixedly connected to the bottom of each of the four second springs 13. The second springs 13 drive the baffles 14 to rebound and reset. When the first block 16 enters the interior of the shell 10, it will press against the baffles 14 to squeeze the second springs 13 and open the slots of the shell 10. When the first block 16 leaves the slots of the shell 10, the second springs 13 will drive the baffles 14 to rebound and block the slots of the shell 10 to prevent impurities from entering the interior.

[0034] like Figure 1 - Figure 10As shown, two fixing blocks 15 are fixedly connected to the inside of the left and right sides of the two second support rings 6. Two first locking blocks 16 are fixedly connected to the top of each fixing block 15. The first locking blocks 16 are correspondingly set with the locking slots inside the outer shell 10. After the first locking blocks 16 are inserted into the inside of the outer shell 10, the bottom of the bracket 11 will enter the inside of the first locking blocks 16 to connect and connect the second support ring 6 and the second connecting ring 7 to prevent the second connecting ring 7 from falling off the upper side wall of the second support ring 6. Two second locking blocks 17 are fixedly connected to the front and rear sides of the bottom wall of the two second connecting rings 7. Two holes 18 are opened on the front and rear sides of the two second support rings 6. Multiple second locking blocks 17 and holes 18 are correspondingly set. After the second locking blocks 17 are inserted into the holes 18, they will be connected to the outer shell 10 through the first locking blocks 16 and then fixed again to prevent the second connecting ring 7 from falling off.

[0035] It should be noted that this utility model is a desulfurization and denitrification combined dust removal flue gas filtration device. Firstly, it connects to a water tank 201 via an external pipe to add denitrifying agent or cleaning agent and clean water. The denitrifying agent or cleaning agent and clean water are drawn from the water tank 201 through the inlet 204 at the input end of the water pump 203. Then, the water is transferred through the first delivery pipe 205 at the output end of the water pump 203 to the connecting pipe 206, flowing into multiple spray pipes 208. Before being sprayed, the denitrifying agent or... The cleaning agent and water flow into the second delivery pipe 211 through the internal threaded pipe 209 at the bottom of the spray pipe 208, which connects to the external threaded pipe 210. The water is then sprayed out through the atomizing nozzle 213. During spraying, the pressure of the water flow drives the atomizing nozzle 213 to rotate. As it rotates, the atomizing nozzle 213 drives the entire second delivery pipe 211 and the first connecting ring 212 at the top of the second delivery pipe 211 to rotate on the top of the external threaded pipe 210, thus achieving the effect of rotating water spraying.

[0036] By pressing the brackets 11 on both sides of the outer casing 10 and sliding them back and forth inside the casing 10, the four first springs 12 inside the casing 10 are compressed. Then, the second connecting ring 7 on the outer side of the casing 10 is pushed to place on the upper side wall of the second support ring 6. At the same time, the first locking blocks 16 on the fixing blocks 15 inside the second support ring 6 will enter the locking grooves inside the casing 10. Releasing the brackets 11 will cause them to spring back through the first springs 12, and the bottom of the brackets 11 will insert into the holes inside the first locking blocks 16 for fixation. After the first locking blocks 16 enter the casing 10, they will compress the second springs 13 through the baffle 14 to open the locking grooves inside the casing 10. This effectively reduces maintenance time and risk, and improves the reliability and efficiency of the system.

[0037] When disassembly is required, press the bracket 11 again to compress the second spring 13. The operator will then pull the entire second connecting ring 7 upward by pressing the bracket 11. The first locking block 16 will then leave the inside of the outer casing 10. Releasing the bracket 11 will reset the casing. The second spring 13 in the slot inside the outer casing 10 will then cause the baffle 14 to spring back and reset, thus sealing the slot of the outer casing 10 to prevent impurities from entering the interior.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
