Description

Technical Field

[0001] This utility model relates to the field of waste incinerator technology, specifically a water spray cooling device for waste incinerators. Background Technology

[0002] Waste incinerators are devices used to process solid waste. They convert waste into ash and heat energy through high-temperature combustion. This process helps reduce the volume of waste and can generate energy. To alleviate the problem of furnace crust formation caused by boiler overheating, which leads to reduced heat exchange and damage to the grate, seriously threatening the safe operation of the boiler, furnace cooling water is introduced. This ensures the safe, economical, continuous, and stable operation of the boiler, while reducing the generation of thermal nitrogen oxides and reducing the consumption of environmentally friendly materials.

[0003] Water spray cooling devices used in waste incinerators typically require water filtration to prevent pipe blockage and nozzle damage. Selecting a suitable filter screen can remove impurities and ensure the normal operation of the system. However, when the filter screen filters the water, it can cause a drop in water pressure, affecting the subsequent atomization effect. Utility Model Content

[0004] The purpose of this invention is to provide a water spray cooling device for waste incinerators, which has the advantages of accelerating the filtered water while filtering it, thus avoiding the impact of filtration on water pressure. This solves the problem that the water spray cooling device reduces water pressure and affects atomization during water filtration.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water spray cooling device for a waste incinerator, comprising a fixed sleeve, a first fixed frame, and a filter screen. Atomizing spray pipes are embedded at the four corners of the bottom of the fixed sleeve. A second fixed frame is embedded on the side of the first fixed frame. Bearings are embedded on both the front and rear sides of the first fixed frame. A first fixed rod is fixedly installed within the inner rings of the two first bearings. A paddle is arranged in a circular array on the outer side of a section inside the first fixed frame. Bearings are embedded on both the front and rear sides of the second fixed frame. A second fixed rod is fixedly installed within the inner rings of the two second bearings. A paddle is arranged in a circular array on the outer side of a section inside the second fixed frame. An insertion hole is provided at the top of the second fixed frame, through which the filter screen is inserted into the second fixed frame.

[0006] Preferably, an air inlet pipe is embedded in the top of the first fixing frame, and a water inlet pipe is embedded in the side of the second fixing frame opposite to the first fixing frame. Both the water inlet pipe and the air inlet pipe are fitted with flanges.

[0007] Preferably, the fixing rods 1 and 2 on the front side of the fixing frame 1 and fixing frame 2 are movably connected by a belt.

[0008] Preferably, both the first fixing rod and the second fixing rod are equipped with baffles at their front ends.

[0009] Preferably, a connecting pipe is embedded at the bottom of the fixing frame, and the bottom of the connecting pipe extends into the inside of the fixing sleeve.

[0010] Preferably, each of the four atomizing nozzles is equipped with a fan-shaped nozzle at its bottom.

[0011] Preferably, a connecting frame is installed on the front side of the fixing sleeve, and the connecting frame is arranged in a rectangular array with connecting holes.

[0012] Preferably, the bottom of the second fixing frame is provided with a fixing groove, and the bottom of the filter screen is inserted into the fixing groove.

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

[0014] This invention incorporates a filter screen, a first paddle, and a second paddle. Water enters the second fixed frame through an inlet pipe, where the filter screen absorbs impurities. Compressed air enters the first fixed frame through an inlet pipe, causing the first paddle inside to rotate. The first paddle drives the first fixed rod to rotate, which in turn drives the second fixed rod via a belt. The second fixed rod then drives the second paddle to rotate, thus transporting the water within the second fixed frame and accelerating its flow. This achieves the effect of simultaneously filtering and accelerating the water flow, preventing the filtration process from affecting water pressure. Attached Figure Description

[0024] Example

[0025] like Figures 1-4As shown, the present invention proposes a water spray cooling device for a waste incinerator, comprising a fixed sleeve 3, a fixed frame 4, and a filter screen 10. Atomizing nozzles 2 are embedded at the four corners of the bottom of the fixed sleeve 3, and fan-shaped nozzles 1 are installed at the bottom of each of the four atomizing nozzles 2. The atomizing nozzles 2 atomize water and deliver the water mist to the fan-shaped nozzles 1, which then spray the water mist out. A fixed frame 2 14 is embedded on the side of the fixed frame 4, and an air inlet pipe 7 is embedded on the top of the fixed frame 4. A water inlet pipe 11 is embedded on the side of the fixed frame 2 14 opposite to the fixed frame 4. Both the water inlet pipe 11 and the air inlet pipe 7 are installed... The device is equipped with flange 8. Air inlet pipe 7 and water inlet pipe 11 are connected via flange 8 to pipes for supplying compressed air and water. Compressed air enters the interior of the first frame 4 through air inlet pipe 7, and water enters the interior of the second frame 14 through water inlet pipe 11. Bearings 5 ​​are embedded in both the front and rear sides of the first frame 4. Fixing rods 6 are fixedly installed on the inner rings of the two bearings 5. Blades 19 are installed in a circular array on the outer side of a section of the fixing rods 6 inside the first frame 4. Bearings 9 are embedded in both the front and rear sides of the second frame 14. Fixing rods 12 are fixedly installed on the inner rings of the two bearings 9. The first frame and the second frame... The first fixing rod 6 and the second fixing rod 12 on the front side of the second fixing frame 14 are movably connected by a belt 16. When the first fixing rod 6 rotates, it drives the second fixing rod 12 to rotate via the belt 16. Both the first fixing rod 6 and the second fixing rod 12 are equipped with baffles 15 at their front ends to prevent the belt 16 from slipping off the first fixing rod 6 and the second fixing rod 12. The second fixing rod 12 is located inside the second fixing frame 14 and has blades 20 arranged in a circular array on its outer side. The top of the second fixing frame 14 has an insertion hole 21 through which the filter screen 10 is inserted into the second fixing frame 14. The bottom of the second fixing frame 14 has a fixing groove 2. 2. The bottom of the filter screen 10 is inserted into the fixing groove 22. The fixing groove 22 fixes the filter screen 10 inside the fixing frame 14 to prevent the filter screen 10 from shaking when filtering water. The bottom of the fixing frame 14 is embedded with a connecting pipe 13. The bottom of the connecting pipe 13 extends into the fixing sleeve 3. Water and compressed air inside the fixing frame 14 enter the fixing sleeve 3 through the connecting pipe 13 for mixing. A connecting frame 17 is installed on the front side of the fixing sleeve 3. The connecting frame 17 has connecting holes 18 in a rectangular array. The connecting frame 17 is fixed to the load-bearing structure through the connecting holes 18 of the connecting frame 17 using bolts or other tools.

[0026] Working principle: The air inlet pipe 7 and the water inlet pipe 11 are connected by a flange 8 to transport compressed air and water. Compressed air enters the interior of the first fixed frame 4 from the air inlet pipe 7, and water enters the interior of the second fixed frame 14 from the water inlet pipe 11. The compressed air entering the first fixed frame 4 impacts the first impeller 19, which drives the first fixed rod 6 to rotate. The filter screen 10 inside the second fixed frame 14 filters the water, adsorbing impurities. When the first fixed rod 6 rotates, it drives the second fixed rod 12 to rotate via the belt 16. The second fixed rod 12 drives the second impeller 20 to rotate. 20. Water filtered inside the second fixed frame 14 is transported to the first fixed frame 4 to accelerate the water flow. Water and compressed air inside the first fixed frame 4 are mixed inside the fixed sleeve 3 through the connecting pipe 13. Water and compressed air inside the fixed sleeve 3 enter the atomizing nozzle 2 at the bottom. The atomizing nozzle 2 atomizes the water and delivers the water mist to the fan-shaped nozzle 1. The fan-shaped nozzle 1 sprays out the water mist. The water mist reduces the temperature inside the waste incinerator, alleviates the furnace overheating caused by the boiler furnace overheating, and at the same time reduces the generation of thermal nitrogen oxides and reduces the consumption of environmental protection materials.
