Description

Technical Field

[0001] This utility model relates to the technical field of exhaust gas treatment equipment, specifically a self-cleaning rotary sprayer for the packing layer of an industrial exhaust gas scrubbing tower. Background Technology

[0002] Industrial production processes generate large amounts of industrial exhaust gases containing dust and harmful gases (such as sulfides, nitrogen oxides, and volatile organic compounds). Direct emission of these gases would cause serious air pollution, necessitating purification treatment via an exhaust gas scrubbing tower to meet emission standards. The packing layer, as the core component of the exhaust gas scrubbing tower, is covered with packing material having a specific pore structure. The exhaust gas and scrubbing liquid come into full contact on the packing surface, removing harmful substances through physical adsorption and chemical neutralization. The cleanliness and permeability of the packing layer directly determine the exhaust gas scrubbing efficiency and purification effect.

[0003] However, the spraying devices used in the packing layers of existing exhaust gas scrubbing towers generally have many technical defects: traditional sprayers are mostly fixed nozzle structures, which limit the spraying range and easily create local spray blind spots in the packing layer, resulting in uneven distribution of the scrubbing liquid. In some areas, the packing cannot fully contact the scrubbing liquid, which not only reduces the exhaust gas purification efficiency but also easily causes pollutants to accumulate on the surface of the packing. Although some rotary sprayers can expand the spraying range, they require additional power drive devices such as motors and reducers, which increases the energy consumption and maintenance costs of the equipment. Moreover, the power components are exposed to humid and corrosive gas environments for a long time, which makes them prone to failure and damage, affecting the stability of continuous operation of the equipment.

[0004] In view of this, we propose a self-cleaning rotary sprayer for the packing layer of the exhaust gas scrubbing tower. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a self-cleaning rotary sprayer for the packing layer of a tail gas scrubbing tower.

[0006] The technical solution of this utility model is:

[0007] A self-cleaning rotary sprayer for the packing layer of a tail gas scrubbing tower includes a spray assembly. The spray assembly includes an outer fixed ring, inside which a hollow turntable is rotatably mounted. Several nozzles are mounted on the bottom of the turntable. A fixed plate is fixedly mounted on the bottom of the outer fixed ring. A notch for the nozzles to pass through is opened on the lower fixed plate. The nozzles are arranged concentrically, with their directions along the tangent of their respective circumferences. The nozzles closest to the fixed plate all point towards the fixed plate during the rotation of the turntable. A water storage tank is connected to the top of the spray assembly via a water inlet pipe, and a water pump is installed at the end of the water inlet pipe near the water storage tank. The nozzles are arranged in concentric circles and along the tangent of their respective circumferences. When combined with the rotation of the turntable, they can form a 360° spray coverage without dead angles, ensuring that the washing liquid is evenly applied to the entire cross-section of the filler layer. The fixed plate is designed so that when the water flow from the outermost ring impacts the fixed plate, it generates a reaction force, which in turn drives the turntable to rotate autonomously with the help of the reaction force along the tangent of the water flow. No additional power unit is required, reducing the energy consumption of the equipment.

[0008] As a preferred technical solution, the spray assembly further includes an upper distribution plate disposed above the turntable, and the upper distribution plate is connected to the turntable by a plurality of evenly distributed connecting pipes. This allows the washing liquid delivered by the water supply pipe to be quickly and evenly distributed to various areas of the turntable, avoiding problems such as insufficient local spray pressure or unstable water output from the nozzles due to uneven distribution of the washing liquid within the turntable.

[0009] As a preferred technical solution, a connecting sleeve is integrally formed at the top center of the upper diversion plate. The connecting sleeve communicates with the interior of the upper diversion plate, and the connecting sleeve is rotatably connected to the water supply pipe through a sealed bearing. This achieves stable communication between the water supply pipe and the rotatable upper diversion plate, ensuring smooth delivery of washing liquid, while the sealing structure prevents leakage of washing liquid at the connection point, reducing resource waste and equipment corrosion risks.

[0010] As a preferred technical solution, several fixing blocks arranged in a circular array are fixedly installed at the bottom of the outer fixing ring. Each fixing block has a fixing hole, and the fixing blocks are fixedly connected to the inner wall of the exhaust gas scrubbing tower by bolts. This ensures the secure installation of the spray assembly inside the tower, preventing the assembly from shifting or loosening due to vibration when the turntable rotates, and ensuring accurate spray positioning.

[0011] As a preferred technical solution, the water tank has a water inlet on the top, and a water tank cover is installed at the water inlet. This facilitates the regular replenishment of washing liquid into the water tank, ensuring sufficient water supply to the spray system and preventing the self-cleaning function from being interrupted due to water shortage.

[0012] As a preferred technical solution, two U-shaped handles are symmetrically fixedly installed on the top of the water tank cover, providing convenient points of force for opening and closing the water tank cover.

[0013] As a preferred technical solution, a support leg is fixedly installed at each of the four corners of the bottom of the water tank. This maintains a certain distance between the bottom of the water tank and the ground, avoiding corrosion and moisture problems caused by direct contact between the water tank and the ground.

[0014] As a preferred technical solution, the outer diameter of the outer fixing ring is equal to the inner diameter of the exhaust gas spray tower. This is used to increase the stability of the outer fixing ring, i.e., the entire spray assembly.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The nozzles of this invention are concentric circles arranged along the tangent of their respective circumferences. When combined with the rotation of the turntable, they can form a 360° spray coverage without dead angles, ensuring that the washing liquid is evenly applied to the entire cross-section of the filler layer. The fixed plate is designed so that when the water flow from the outermost ring impacts the fixed plate, it generates a reaction force, which in turn drives the turntable to rotate autonomously with the help of the reaction force along the tangent of the water flow. No additional power device is required, thus reducing the energy consumption of the equipment. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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] Please see Figures 1-4 This utility model provides a technical solution:

[0025] The exhaust gas scrubbing tower packing layer self-cleaning rotary sprayer includes a spray assembly 3, which includes an outer fixing ring 30. A hollow turntable 31 is rotatably installed inside the outer fixing ring 30. Several nozzles 33 are installed at the bottom of the turntable 31. A fixing plate 34 is fixedly installed at the bottom of the outer fixing ring 30. A notch 340 for the nozzles 33 to pass through is opened on the lower fixing plate 34. The nozzles 33 are arranged in concentric circles, and their directions are along the tangent of their respective circumferences. The nozzles 33 closest to the fixing plate 34 all point to the fixing plate 34 during the rotation of the turntable 31. A water storage tank 1 is connected to the top of the spray assembly 3 via a water supply pipe 4. A water pump 40 is installed at the end of the water supply pipe 4 near the water storage tank 1. The nozzles 33 are concentric circles and set along the tangent of their respective circumferences. When they rotate with the turntable 31, they can form a 360° spray coverage without dead angles, ensuring that the washing liquid is evenly applied to the entire cross-section of the filler layer. When the water flow on the outermost ring of the fixed plate 34 impacts the fixed plate 34, it generates a reaction force and simultaneously drives the turntable 31 to rotate autonomously with the reaction force in the tangential direction of the water flow. No additional power device is required, reducing the energy consumption of the equipment.

[0026] In a preferred embodiment, the spray assembly 3 further includes an upper diverter plate 35 disposed above the turntable 31, and the upper diverter plate 35 is connected to the turntable 31 by a plurality of evenly distributed connecting pipes 38. This allows the washing liquid delivered by the water supply pipe 4 to be quickly and evenly distributed to various areas of the turntable 31, avoiding problems such as insufficient local spray pressure or unstable water output from the nozzles 33 caused by uneven distribution of the washing liquid within the turntable 31.

[0027] In a preferred embodiment, a connecting sleeve 37 is integrally formed at the top center of the upper diversion plate 35. The connecting sleeve 37 communicates with the interior of the upper diversion plate 35, and the connecting sleeve 37 is rotatably connected to the water supply pipe 4 via a sealed bearing 36. This achieves stable communication between the water supply pipe 4 and the rotatable upper diversion plate 35, ensuring smooth delivery of the washing liquid, while the sealing structure prevents leakage of the washing liquid at the connection point, reducing resource waste and the risk of equipment corrosion.

[0028] In a preferred embodiment, the bottom of the outer fixing ring 30 is fixedly equipped with a plurality of fixing blocks 32 arranged in a circular array. Each fixing block 32 has a fixing hole, and the fixing blocks 32 are fixedly connected to the inner wall of the exhaust gas scrubbing tower by bolts. This ensures that the spray assembly 3 is firmly installed in the tower, preventing the assembly from shifting or loosening due to vibration when the turntable 31 rotates, and ensuring accurate spray positioning.

[0029] As a preferred embodiment, the water tank 1 has a water inlet on its top, and a water tank cover 10 is installed at the water inlet. This facilitates the periodic replenishment of washing liquid to the water tank 1, ensuring sufficient water supply to the spray system and preventing the self-cleaning function from being interrupted due to water shortage.

[0030] As a preferred embodiment, two lid handles 11 are symmetrically fixedly installed on the top of the water tank lid 10, and the lid handles 11 are U-shaped. This provides a convenient point of force for opening and closing the water tank lid 10.

[0031] As a preferred embodiment, a support leg 2 is fixedly installed at each of the four corners of the bottom of the water tank 1. This maintains a certain distance between the bottom of the water tank 1 and the ground, preventing corrosion and moisture problems caused by direct contact between the water tank 1 and the ground.

[0032] In this preferred embodiment, the outer diameter of the outer fixing ring 30 is equal to the inner diameter of the exhaust gas spray tower. This is used to increase the stability of the outer fixing ring 30, i.e., the entire spray assembly 3.

[0033] In use, the self-cleaning rotary sprayer for the packing layer of the exhaust gas scrubbing tower of this utility model first starts the water pump 40 to transport the washing liquid in the water storage tank 1 to the spray assembly 3 through the water supply pipe 4. The water storage tank 1 is replenished through the water inlet and the support legs 2 are moisture-proof to ensure a stable water supply. The washing liquid enters the upper distribution plate 35 through the connecting sleeve 37 (rotatably connected to the water supply pipe 4 through the sealed bearing 36), and is then distributed to the hollow turntable 31 by the evenly distributed connecting pipes 38. Because the nozzles 33 at the bottom of the turntable 31 are concentric circles and arranged along the circumferential tangential direction, the water jet generates a tangential reaction force. Simultaneously, the nozzles 33 near the fixed plate 34 impact the fixed plate 34, generating additional reaction force, which together drive the turntable 31 to rotate autonomously within the outer fixed ring 30 (firmly connected to the tower wall through the fixed block 32, with the outer diameter matching the inner diameter of the tower). The nozzles 33 rotate smoothly through the notch 340 of the fixed plate 34 to achieve 360° spraying without dead angles. The rotating nozzles 33 evenly spray the high-pressure washing liquid onto the packing layer to complete the exhaust gas purification. At the same time, they powerfully flush the packing layer and the fixed plate 34 to remove deposits, achieving self-cleaning. No additional power is required throughout the process, balancing washing efficiency and stable equipment operation.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
