Description

Technical Field

[0001] This utility model relates to the field of water softening equipment technology, and in particular to an activated carbon filter for softening water sources for incineration power generation. Background Technology

[0002] The safe and stable operation of the boiler system in waste-to-energy incineration directly affects power generation efficiency and environmental benefits. However, due to the influence of the water source collected during the incineration process, the water quality generally suffers from high hardness and high salinity, easily leading to scale formation on the boiler's heating surfaces. This creates thermal resistance and overheating, reducing the boiler's heat transfer efficiency and potentially causing safety issues such as boiler tube rupture. Therefore, it is necessary to soften the raw water before it is used in the boiler. This is achieved by sequentially passing the raw water through an activated carbon filter and a softening tank. The activated carbon blocks in the activated carbon filter physically adsorb and remove chlorine, organic matter, and impurities from the raw water. The resin or reverse osmosis membrane in the softening tank then treats the water to remove calcium and magnesium ions, improving the quality of the boiler feedwater and reducing scale formation. However, the activated carbon blocks in the activated carbon filter can only passively accept the water flow, resulting in some activated carbon blocks not being able to uniformly contact the organic matter or impurities in the raw water, failing to fully exert their physical adsorption effect and causing waste. Therefore, designing an activated carbon filter for softening the water source in waste-to-energy incineration that can promote contact between hard water and activated carbon blocks and improve the adsorption effect has become an urgent technical problem to be solved. Summary of the Invention

[0003] To solve the above problems, this utility model provides an activated carbon filter for softening water sources in incineration power generation.

[0004] The present invention relates to an activated carbon filter for softening water in incineration power generation, comprising a filter box, an inlet pipe connected to the top of the filter box and an outlet pipe connected to the bottom of the filter box, both of which are equipped with solenoid valves; an upper perforated plate and a lower perforated plate connected inside the filter box, a cavity above the upper perforated plate and a filter water cavity below the lower perforated plate, and several activated carbon blocks disposed between the upper and lower perforated plates; an air jet stirring structure connected to the outer wall of the filter box, the air jet stirring structure comprising an air pump and multiple sets of spray guns, each spray gun having a nozzle extending into the filter box and the nozzle being aligned with the activated carbon blocks; and an air pump having an air inlet pipe connected to the cavity and an air outlet pipe connected to the spray guns.

[0005] With the above structure, a water pump connected to the water source via the inlet pipe is turned on and the solenoid valve is opened to deliver raw water into the filter box. After entering the filter box, the raw water passes sequentially through the cavity, upper perforated plate, activated carbon block, lower perforated plate, and filter water chamber. The upper perforated plate blocks large debris, and the activated carbon block physically adsorbs chlorine, organic matter, and impurity particles in the raw water. The lower perforated plate carries the activated carbon block. The raw water flowing into the filter water chamber flows into the softened water tank via the outlet pipe for further removal of calcium and magnesium ions. The air pump is then turned on, drawing air from the cavity through the inlet pipe and supplying air to the spray gun through the outlet pipe. The nozzle of the spray gun... Insert the air into the filter box and spray it towards the activated carbon block. The air forms bubbles in the raw water, agitating the raw water and ensuring full contact with the activated carbon block. This fully utilizes the physical adsorption performance of the activated carbon block without impacting or damaging it. The bubbles float upwards while agitating the raw water and eventually pass through the upper perforated plate back into the cavity, completing the air circulation. This achieves the goal of spraying air to agitate the raw water and ensure contact with the activated carbon block during adsorption, avoiding waste caused by insufficient physical adsorption of the activated carbon block. The air returns to the cavity after agitating the raw water for reuse, ensuring stable air pressure inside the filter box.

[0006] As a further improvement of this utility model, the upper and lower sides of the activated carbon block are provided with fiber media, which are attached to the upper and lower perforated plates.

[0007] By adopting the above structure and setting up a fiber medium made of materials such as cotton, glass fiber, and polytetrafluoroethylene, the activated carbon blocks are prevented from directly hitting the upper and lower perforated plates, thereby improving the adsorption capacity for residual chlorine and odor molecules in the raw water.

[0008] As a further improvement of this utility model, the filter box has a cylindrical structure, and the spray guns are arranged at equal intervals along the outer circumference of the filter box.

[0009] With the above structure, the filter box is cylindrical and the spray guns are arranged at equal intervals along the outer circumference of the filter box, so that when the air sprayed from the nozzle forms bubbles in the raw water, the distribution of bubbles is more uniform.

[0010] As a further improvement of this utility model, the water outlet direction of the nozzle forms an angle of less than 90° with the circular tangent of the filter box.

[0011] With the above structure, the water outlet direction of the nozzle forms an angle of less than 90° with the circular tangent of the filter box. The sprayed air pushes the raw water to form a vortex, which further promotes the raw water to come into contact with different activated carbon blocks for adsorption treatment.

[0012] As a further improvement of this utility model, an air inlet connected to an air inlet pipe is provided on one side of the cavity. The air inlet is connected to a U-shaped pipe that extends into the cavity. The bottom of the U-shaped pipe is provided with a drain outlet facing the upper perforated plate. The upper end of the U-shaped pipe is provided with a baffle plate, and the baffle plate is provided with a vent hole.

[0013] With the above structure, a U-shaped tube extending into the cavity is connected through the air inlet. The air drawn in by the air pump first passes through the U-shaped tube and then enters the air inlet pipe. A baffle plate with vent holes is provided at the upper end of the U-shaped tube. When water splashes or droplets are carried into the U-shaped tube by the airflow, they are first blocked by the baffle plate, reducing the amount of water entering the U-shaped tube. The water that enters the U-shaped tube will flow along the inner wall of the U-shaped tube to the bottom of the U-shaped tube and flow out from the drain outlet with an opening area smaller than the total area of ​​the vent holes, falling onto the upper perforated plate. This prevents the air pump from drawing in a large amount of water, which would accelerate the corrosion of internal parts. Attached Figure Description

Detailed Implementation

[0019] like Figures 1-4 The activated carbon filter shown is used for softening water source for incineration power generation. It includes a filter box 1, with an inlet pipe 2 connected to the top and an outlet pipe 3 connected to the bottom. Solenoid valves 4 are installed on both the inlet pipe 2 and the outlet pipe 3. An upper perforated plate 5 and a lower perforated plate 6 are connected inside the filter box 1. There is a cavity 7 above the upper perforated plate 5 and a filter water cavity 8 below the lower perforated plate 6. Several activated carbon blocks 9 are arranged between the upper perforated plate 5 and the lower perforated plate 6. An air jet stirring structure is connected to the outer wall of the filter box 1. The air jet stirring structure includes an air pump 10 and multiple sets of spray guns 11. The spray guns 11 are equipped with nozzles 12 that extend into the filter box 1 and are positioned to be aligned with the activated carbon blocks 9. The air pump 10 is equipped with an air inlet pipe 13 that connects to the cavity 7 and an air outlet pipe 14 that connects to the spray guns 11.

[0020] A water pump connected to the water source via inlet pipe 2 is turned on and solenoid valve 4 is opened, supplying raw water into filter box 1. After entering filter box 1, the raw water sequentially passes through cavity 7, upper perforated plate 5, activated carbon block 9, lower perforated plate 6, and filter water chamber 8. Upper perforated plate 5 blocks large debris, activated carbon block 9 physically adsorbs chlorine, organic matter, and impurity particles in the raw water, and lower perforated plate 6 carries activated carbon block 9. The raw water flowing into filter water chamber 8 flows into softened water tank via outlet pipe 3 for further removal of calcium and magnesium ions. Meanwhile, air pump 10 is turned on, drawing air from cavity 7 via air inlet pipe 13 and supplying air to spray gun 11 via air outlet pipe 14. The nozzle 12 extends into the filter box 1 and sprays air towards the location of the activated carbon block 9. The air forms bubbles in the raw water, agitating the raw water and ensuring full contact with the activated carbon block 9. This fully utilizes the physical adsorption performance of the activated carbon block 9 without causing impact damage to it. The bubbles float upwards while agitating the raw water and finally pass through the upper perforated plate 5 back to the cavity 7, completing the air circulation. This achieves the goal of spraying air to agitate the raw water and ensure contact with the activated carbon block 9 while it is adsorbing, avoiding waste caused by insufficient physical adsorption of the activated carbon block 9. After agitating the raw water, the air returns to the cavity 7 for recycling, ensuring stable air pressure inside the filter box 1.

[0021] The activated carbon block 9 has fiber media 15 on its upper and lower sides, and the fiber media 15 is attached to the upper perforated plate 5 and the lower perforated plate 6.

[0022] By setting up a fiber medium 15 composed of materials such as cotton, glass fiber, and polytetrafluoroethylene, the activated carbon block 9 is prevented from directly hitting the upper orifice plate 5 and the lower orifice plate 6, thereby improving the adsorption capacity for residual chlorine and odor molecules in the raw water.

[0023] The filter box 1 is a cylindrical structure, and the spray guns 11 are arranged at equal intervals along the outer circumference of the filter box 1.

[0024] Since the filter box 1 is a cylindrical structure, the spray guns 11 are arranged at equal intervals along the outer circumference of the filter box 1, so that when the air sprayed by the nozzles 12 forms bubbles in the raw water, the distribution of bubbles is more uniform.

[0025] The water outlet direction of nozzle 12 forms an angle of less than 90° with the circular tangent of filter box 1.

[0026] The water outlet direction of the nozzle 12 forms an angle of less than 90° with the circular tangent of the filter box 1. The sprayed air pushes the raw water to form a vortex, which further promotes the raw water to come into contact with different activated carbon blocks 9 for adsorption treatment.

[0027] An air inlet connected to an air inlet pipe 13 is provided on one side of the cavity 7. The air inlet is connected to a U-shaped pipe 16 that extends into the cavity 7. The bottom of the U-shaped pipe 16 is provided with a drain outlet 17 facing the upper perforated plate 5. The upper end of the U-shaped pipe 16 is provided with a baffle plate 18, and the baffle plate 18 is provided with a vent hole 19.

[0028] A U-shaped tube 16 extending into the cavity 7 is connected through the air inlet. The air drawn in by the air pump 10 first passes through the U-shaped tube 16 and then enters the air inlet pipe 13. A baffle plate 18 is provided at the upper end of the U-shaped tube 16, and a vent hole 19 is provided on the baffle plate 18. When water splashes or droplets are carried into the U-shaped tube 16 by the airflow, they are first blocked by the baffle plate 18, reducing the amount of water entering the U-shaped tube 16. The water that enters the U-shaped tube 16 will flow along the inner wall of the U-shaped tube 16 to the bottom of the U-shaped tube 16 and flow out from the drain outlet 17, whose opening area is smaller than the total area of ​​the vent hole 19, and fall onto the upper perforated plate 5, thus preventing the air pump 10 from drawing in a large amount of water and accelerating the corrosion of internal parts.
