[0002] In the waste treatment, waste incineration is the most widely used waste treatment method. Waste incineration is to put the waste into the incinerator for burning, and waste incineration fly ash is one of the products of waste incineration. Waste incineration fly ash is a powdery substance with light bulk density and small particle size collected in the flue gas duct, flue gas purification, separator and dust collector during the waste incineration process. Fly ash is a solid hazardous waste because it contains heavy metals, soluble salts and organic chlorides with high leaching toxicity. Incineration fly ash needs to be washed with water for dechlorination before entering the cement kiln or being recycled.

[0021] The present invention provides a uniformly heated waste incineration fly ash washing liquid evaporation and crystallization device, which has the following beneficial effects:

[0022] 1. The uniformly heated waste incineration fly ash washing liquid evaporation crystallization equipment utilizes the rotation of the servo motor output end and the fixed installation of the coupling to drive the rotating shaft to rotate, so that the rotating shaft can be used to drive the blades to rotate quickly, and combined with the inclined installation of the blades, the blades blow the air in the cylindrical tube toward the direction of the right-angle lever, so that suction can be generated in the cylindrical tube to suck out the smoke generated by the combustion in the combustion furnace. As the smoke carries the fly ash out, it is helpful to treat the waste incineration fly ash.

[0023] 2. The evenly heated waste incineration fly ash washing liquid evaporation crystallization equipment, as the dust impurities carried by the flue gas enter the interior of the airway, uses the bottom end of the airway to extend to a position close to the bottom of the inner cavity of the solution tank, so that the flue gas is fully in contact with the dechlorination liquid in the solution tank, and the solution tank can be used to adsorb the dust impurities remaining in the flue gas, so that the dust impurities are separated from the flue gas, which can achieve the effect of removing impurities.

[0028] 7. The evenly heated waste incineration fly ash washing liquid evaporation crystallization equipment is installed at the smoke inlet of the flue through a conical bucket. As the smoke floats upward, the smoke passes through the round hole into the flue, and large particles of unburned materials are intercepted to achieve a filtering effect, and then fall into the interior of the furnace again for secondary combustion, so as to pre-treat the waste incineration fly ash.

[0029] 8. The evenly heated waste incineration fly ash washing liquid evaporation crystallization equipment can apply a pushing force to the grate through the pressure teeth as the baffle presses the pressure teeth, so that the grate is tilted, and as the waste materials burn, the waste materials will move slowly due to the tilting effect, so the waste materials can be turned over, making the waste materials burn more fully.

[0041] A uniformly heated waste incineration fly ash water washing liquid evaporation and crystallization device comprises a combustion furnace 1;

[0042] The air suction mechanism 2 is used to extract the smoke and keep the smoke flowing smoothly. The air suction mechanism 2 is installed at the smoke exhaust port of the combustion furnace 1;

[0043] The air suction mechanism 2 includes a cylindrical barrel 21 and a servo motor 22. The round mouth of the cylindrical barrel 21 is connected to the smoke exhaust port of the combustion furnace 1. The servo motor 22 is fixedly installed at one end of the cylindrical barrel 21 away from the combustion furnace 1. A rotating shaft 23 is rotatably installed in the middle of the inner cavity of the cylindrical barrel 21. The output end of the servo motor 22 is fixedly installed between the rotating shaft 23 through a coupling. A blade 24 is fixedly installed on the outer cylindrical surface of the rotating shaft 23 and at one end away from the servo motor 22. A right-angle lever is fixedly installed in the middle of the outer cylindrical surface of the rotating shaft 23. 25. The staff starts the servo motor 22 to work, and uses the rotation of the output end of the servo motor 22 and the fixed installation of the coupling to drive the rotating shaft 23 to rotate, so that the rotating shaft 23 can drive the blade 24 to rotate quickly, and combined with the inclined installation of the blade 24, the blade 24 blows the air in the cylindrical tube 21 toward the direction of the right-angle lever 25, so that suction can be generated in the cylindrical tube 21, and the smoke generated by the combustion in the combustion furnace 1 is sucked out, and the fly ash is sucked out along with the smoke;

[0044] There are five blades 24 , and the five blades 24 are evenly installed on the outer circumferential surface of the rotating shaft 23 and at one end away from the servo motor 22 . The blades 24 are installed obliquely, and the right-angle lever 25 is evenly fixed in the middle of the outer circumferential surface of the rotating shaft 23 .

[0045] The second embodiment is based on the first embodiment. Figures 1 to 5 As shown:

[0046] A fly ash treatment mechanism 3, which is used for evaporating and crystallizing the fly ash washing liquid, and is installed at the bottom of the outer circumference of the cylindrical barrel 21;

[0047] The fly ash treatment mechanism 3 includes a solution tank 31 and an air duct 32. The air duct 32 is fixedly installed at the center of the solution tank 31. The top of the air duct 32 is connected to the bottom of the outer circumference of the cylindrical barrel 21. A spray assembly 33 is installed on the outer circumference of the solution tank 31 and close to the air duct 32. An exhaust pipe 34 is connected to the conical surface of the surface of the solution tank 31. A cylindrical connecting rod 35 is rotatably installed at the center of the air duct 32. A disc 36 is fixedly connected to the top of the cylindrical connecting rod 35. The edge of the top of the disc 36 and the position close to the right-angle lever 25 are connected to the exhaust pipe 34. A force-bearing protrusion 37 is fixedly installed, and the force-bearing protrusion 37 is meshed with the right-angle lever 25. A turning plate 38 is fixedly installed at the bottom end of the cylindrical connecting rod 35, and a V-shaped notch 39 is opened on the top of the turning plate 38. As the dust and impurities carried by the flue gas enter the interior of the airway 32, the bottom end of the airway 32 is extended to a position close to the bottom of the inner cavity of the solution tank 31, so that the flue gas is fully in contact with the dechlorination liquid in the solution tank 31, and the solution tank 31 can be used to adsorb the dust and impurities remaining in the flue gas, so that the dust and impurities are separated from the flue gas.

[0048] The cylindrical connecting rod 35 passes through the center of the airway 32, and the force-bearing protrusions 37 are evenly installed on the edge of the top of the disc 36. As the rotating shaft 23 drives the blades 24 to rotate, the flue gas is sucked into the cylindrical tube 21, and the airway 32 is used to communicate with the cylindrical tube 21, so that the flue gas is guided by the airway 32 and discharged from the bottom of the airway 32 into the interior of the solution tank 31, so that the flue gas contacts the dechlorination liquid in the solution tank 31. According to the principle of heat transfer, the dechlorination liquid absorbs the heat in the flue gas. As the flue gas continues to enter the interior of the solution tank 31, the temperature of the dechlorination liquid can be increased until it reaches boiling, and the steam is discharged from the exhaust pipe 34, thereby causing the waste incineration fly ash water washing liquid to evaporate and crystallize.

[0049] As the servo motor 22 drives the rotating shaft 23 to rotate, the right-angle lever 25 rotates together with the rotating shaft 23, and the force-bearing protrusion 37 is meshed with the right-angle lever 25, so that the force-bearing protrusion 37 is subjected to a pushing force, and the cylindrical connecting rod 35 is driven to rotate, so that the flipping plate 38 rotates together with the cylindrical connecting rod 35. Through the rotation of the flipping plate 38, the dechlorination liquid in the solution tank 31 can be stirred, so that after the flue gas enters the solution tank 31, the dechlorination liquid can be heated evenly.

[0050] The spray assembly 33 includes a pump body 331 and an annular nozzle 332. The pump body 331 is fixedly installed in the middle of the outer surface of the solution tank 31. The annular nozzle 332 is fixedly installed in the airway 32 and close to the cylindrical connecting rod 35. The cylindrical connecting rod 35 passes through the center of the annular nozzle 332. The water inlet end of the pump body 331 extends to the inside of the solution tank 31. A filter screen 333 is fixedly installed at the water inlet of the pump body 331. A right-angle pipe 334 is connected to the water outlet of the pump body 331. The top of the right-angle pipe 334 passes through the solution tank 31 and the airway 32, and the liquid outlet of the right-angle pipe 334 is connected to the annular nozzle. The liquid inlet of the nozzle 332 is connected, and the staff turns on the pump body 331 to work. By using the suction force generated by the pump body 331, part of the dechlorination liquid in the solution tank 31 can be sucked out from the position of the filter screen 333, and the dechlorination liquid is transported by the right-angle pipe 334 so that it enters the interior of the annular nozzle 332 and is sprayed upward from the nozzle on the top of the annular nozzle 332, so that the liquid water mist is sprayed upward, and the flue gas carries the dust and impurities and moves from top to bottom. The two move in opposite directions, so that the water mist can fully contact with the flue gas, which is convenient for the dust and impurity particles to stick together and remove the dust and impurities.

[0051] The bending part of the outer circumferential surface of the right-angle tube 334 is sealed and installed with the solution tank 31, and the nozzle of the annular nozzle 332 faces upward.

[0052] The third embodiment is based on the first and second embodiments. Figures 1 to 8 As shown:

[0053] The combustion furnace 1 includes a furnace body 101 and a flue 102. The position of the furnace body 101 corresponds to the position of the solution tank 31. The bottom end of the flue 102 is connected to the top of the combustion furnace 1. The smoke outlet of the flue 102 is connected to the air inlet of the cylindrical tube 21. A burner 103 is installed inside the furnace body 101 near the bottom. A feed port 104 is provided on the surface of the furnace body 101 near the burner 103. A conical bucket 105 is fixedly installed on the conical surface of the inner cavity of the flue 102. A circular hole 106 is provided on the conical surface of the conical bucket 105, and a support assembly 107 is installed inside the furnace body 101 and near the feed port 104. The conical bucket 105 is installed at the smoke inlet of the flue 102. As the smoke floats upward, the smoke passes through the circular hole 106 into the flue 102, while large particles of unburned materials are intercepted to achieve a filtering effect, and fall into the interior of the furnace body 101 again for secondary combustion, thereby pre-treating the waste incineration fly ash.

[0054] The tip of the conical bucket 105 faces upward, and the round holes 106 are evenly arranged on the conical surface of the conical bucket 105 .

[0055] The support assembly 107 includes a baffle 1071 and a grate 1072. The baffle 1071 is hinged on the outer surface of the furnace body 101 and is close to the feed port 104. The grate 1072 is rotatably installed inside the furnace body 101 and is close to the burner 103. The grate 1072 is installed directly above the burner 103. An electric telescopic rod 1073 is hinged on the outer surface of the furnace body 101 and is close to the top. The telescopic end of the electric telescopic rod 1073 is hinged to the middle of the surface of the baffle 1071. A pressure tooth 1074 is fixedly connected to the side of the surface of the grate 1072 and is close to the feed port 104. A U-shaped notch 1075 is provided on the outer surface of the furnace body 101 and is close to the pressure tooth 1074. The inner wall of the furnace body 101 and is close to the grate 1072 A base 1076 is fixedly installed, and the staff turns on the electric telescopic rod 1073 to work. By utilizing the contraction of the telescopic end of the electric telescopic rod 1073, a pulling force can be applied to the baffle 1071, so that the baffle 1071 rotates clockwise to the side away from the feed port 104, so that the feed port 104 can be opened, and garbage materials are put into the interior of the furnace body 101 from the feed port 104, and the garbage materials are ignited by the burner 103, so that the garbage materials can be burned, and the telescopic end of the electric telescopic rod 1073 is extended, so that the baffle 1071 is pressed by the telescopic end of the electric telescopic rod 1073, so that the baffle 1071 can rotate counterclockwise, and the baffle 1071 blocks the feed port 104 again to reduce the heat dissipation when the garbage is burned.

[0056] The pressure tooth 1074 is installed at an angle, and the position of the pressure tooth 1074 corresponds to the position of the U-shaped notch 1075. The opening of the U-shaped notch 1075 faces upward. As the baffle 1071 blocks the feed port 104, the pressure tooth 1074 is pressed by the baffle 1071, and a pushing force can be applied to the grate 1072 through the pressure tooth 1074, so that the grate 1072 is tilted. As the garbage material burns, the garbage material will move slowly due to the tilting effect, so the garbage material can be turned over, making the garbage material burn more efficiently.

[0057] When in use, the staff first opens the top cover at the top side of the solution tank 31, injects an appropriate amount of dechlorination liquid into the solution tank 31, and then installs and fixes the top cover;

[0058] At this time, the staff starts the electric telescopic rod 1073 to work, and uses the contraction of the telescopic end of the electric telescopic rod 1073 to apply a pulling force to the baffle 1071, so that the baffle 1071 rotates clockwise to the side away from the feed port 104, so that the feed port 104 can be opened, and garbage materials are put into the furnace body 101 from the feed port 104, and the garbage materials are ignited by the burner 103, so that the garbage materials can be burned, and the telescopic end of the electric telescopic rod 1073 is extended, so that the baffle 1071 is pressed by the telescopic end of the electric telescopic rod 1073, so that the baffle 1071 can rotate counterclockwise, and the baffle 1071 blocks the feed port 104 again, reducing the heat dissipation when the garbage is burned;

[0059] The conical bucket 105 is installed at the smoke inlet of the flue 102. As the smoke floats upward, the smoke passes through the circular hole 106 and enters the flue 102, while the large particles of unburned materials are intercepted and fall into the furnace body 101 again for secondary combustion.

[0060] At the same time, as the baffle 1071 blocks the feed port 104, the pressure-bearing teeth 1074 are pressed by the baffle 1071, and the pressure-bearing teeth 1074 can apply a turning force to the grate 1072, so that the grate 1072 is tilted, and as the garbage material burns, the garbage material will move slowly due to the tilting effect, so that the garbage material can be turned over, so that the garbage material burns more efficiently;

[0061] The staff turns on the servo motor 22 to work, and uses the rotation of the output end of the servo motor 22 and the fixed installation of the coupling to drive the rotating shaft 23 to rotate, so that the rotating shaft 23 can drive the blade 24 to rotate quickly, and combined with the inclined installation of the blade 24, the blade 24 blows the air in the cylindrical tube 21 toward the direction of the right-angle lever 25, so that suction is generated in the cylindrical tube 21, and the smoke generated by the combustion in the combustion furnace 1 is sucked out, and the fly ash is sucked out along with the smoke;

[0062] As the dust and impurities carried by the flue gas enter the interior of the airway 32, the bottom end of the airway 32 is extended to a position close to the bottom of the inner cavity of the solution tank 31, so that the flue gas is fully in contact with the dechlorination liquid in the solution tank 31, and the solution tank 31 can be used to adsorb the dust and impurities remaining in the flue gas, so that the dust and impurities are separated from the flue gas;

[0063] The staff turns on the pump body 331 to work, and uses the suction force generated by the pump body 331 to suck out part of the dechlorination liquid in the solution tank 31 from the position of the filter screen 333, and under the transportation of the right-angle pipe 334, the dechlorination liquid enters the interior of the annular nozzle 332, and sprays upward from the nozzle on the top of the annular nozzle 332, so that the liquid water mist sprays upward, and the flue gas carries the dust and impurities and moves from top to bottom. The two move in opposite directions, so that the water mist and the flue gas can fully contact, so that the dust and impurity particles are easy to stick together, and the dust and impurities are easy to remove;

[0064] Moreover, as the rotating shaft 23 drives the blades 24 to rotate, the flue gas is sucked into the cylindrical barrel 21, and the airway 32 is used to communicate with the cylindrical barrel 21, so that the flue gas is guided by the airway 32 and discharged from the bottom of the airway 32 into the interior of the solution tank 31, so that the flue gas contacts the dechlorination liquid in the solution tank 31. According to the heat transfer principle, the dechlorination liquid absorbs the heat in the flue gas. As the flue gas continues to enter the interior of the solution tank 31, the temperature of the dechlorination liquid can be increased until it reaches boiling, and the steam is discharged from the exhaust pipe 34, so that the waste incineration fly ash washing liquid evaporates and crystallizes;

[0065] As the servo motor 22 drives the rotating shaft 23 to rotate, the right-angle lever 25 rotates together with the rotating shaft 23, and the force-bearing protrusion 37 is meshed with the right-angle lever 25, so that the force-bearing protrusion 37 is subjected to a pushing force, and the cylindrical connecting rod 35 is driven to rotate, so that the flipping plate 38 rotates together with the cylindrical connecting rod 35. Through the rotation of the flipping plate 38, the dechlorination liquid in the solution tank 31 can be stirred, so that after the flue gas enters the solution tank 31, the dechlorination liquid can be heated evenly.
