Description

Technical Field

[0001] The present invention relates to the technical field of domestic waste treatment, and more specifically to a method for in-situ production of new materials using fly ash from waste incineration. Background Art

[0002] With the rapid development of modern urban construction, the amount of urban domestic waste is increasing. The amount of domestic waste in my country continues to increase at a rate of about 10% every year. Waste incineration power generation is the best way to dispose of domestic waste in a "reduced, harmless and resource-based" way. However, after incineration, fly ash accounting for about 3%-5% of the weight of the waste and ash residue accounting for 25%-30% of the weight of the waste are produced; "Fly ash" is a general term for the bottom ash settled at the bottom of the waste incineration plant, waste incineration flue gas emissions, purification systems, capture materials and flues and chimneys. Because fly ash contains dioxins and heavy metals, it must be solidified / stabilized, and the treated products can be landfilled and recycled; on the other hand, although the amount of heavy metal leaching in the ash residue basically meets the requirements of the "Hazardous Waste Identification Standard-Leaching Toxicity Identification", due to the cumulative nature of ion dissolution, and the ash residue may be affected by the environment during storage, disposal and resource utilization, resulting in changes in the leaching of heavy metals, posing a threat to the surrounding environment and human health, so the ash residue is a potentially hazardous waste and must also be harmlessly disposed of and recycled.

[0003] As the main equipment for removing dioxins from fly ash during garbage incineration, the rotary kiln incinerator is suitable for almost all garbage that can be incinerated. The main body of the rotary kiln incinerator is a rotatable horizontal cylindrical shell made of steel plates and lined with refractory materials. The pipe has a certain inclination. After the garbage enters the rotary kiln, it slowly moves to the tail as the cylinder rotates. The rotation of the kiln body allows the material to fully contact with the combustion air during the combustion process. After drying and burning to remove harmful substances in the garbage, the garbage fly ash is discharged to the post-treatment system for waste heat recovery, rapid cooling and dust removal, acid gas absorption, flue gas emission, etc.

[0004] In the actual design process of the rotary kiln, it is necessary to coordinate various aspects such as inclination, length and rotation speed. After the garbage enters the rotary kiln for incineration, the contact between the garbage and the inner wall of the rotary kiln depends on the rotation of the rotary kiln and the weight of the garbage itself, resulting in a waste of temperature of the inner wall of the rotary kiln. In order to reduce the amount of dioxins produced by garbage incineration and ensure sufficient combustion of the garbage, the rotary kiln is long, large in size and occupies a large area, resulting in a waste of installation space, making the garbage stay on the inner wall of the rotary kiln within 0.5 to 2 hours, and the efficiency of removing harmful substances by garbage combustion is low. In view of this, we propose a garbage incineration fly ash dioxin pyrolysis system. Summary of the invention

[0005] The purpose of the present invention is to provide a method for in-situ production of new materials using fly ash from garbage incineration, so as to solve the technical problem of low efficiency in removing harmful substances from garbage combustion in a rotary kiln incinerator.

[0006] In order to solve the above technical problems, the present invention provides the following technical solution: a method for in-situ production of new materials using fly ash from waste incineration, comprising the following steps: S1: Sending domestic waste into a rotary kiln incinerator for incineration to remove harmful substances in the domestic waste and obtain harmless domestic waste fly ash; the rotary kiln incinerator comprises a base, a rotating structure A is fixedly arranged on the base, a furnace body mechanism is arranged on the rotating structure A, a centrifugal material turning mechanism is arranged on the furnace body mechanism, and a rotating mechanism B is arranged at the tail end of the base of the furnace body mechanism; The furnace body mechanism comprises an incineration tube, which is in a horizontal structure and fixed at the rotating end of the rotating structure A. The inner surface of the incineration tube is in a circular structure with equal spacing and is provided with a plurality of thread guide grooves; The centrifugal material turning mechanism comprises a centrifugal assembly, the centrifugal assembly is arranged on the incineration tube, and a material turning assembly is arranged on the centrifugal assembly; The rotating mechanism B includes a first output end and a second output end, the centrifugal component input end is fixedly connected to the first output end, and the flipping component is movably connected to the second output end. The first output end and the second output end rotate simultaneously, causing the centrifugal component and the flipping component to form a centrifugal rotation state, and the first output end rotates relative to the second output end, causing the centrifugal component and the flipping component to form a flipping rotation state. The present invention, through the structural design of the rotary kiln incinerator, sends garbage into the incineration tube for incineration to remove harmful substances. In the early stage of removing harmful substances from the garbage, the centrifugal component and the material turning component are in a centrifugal rotating state by controlling the rotating mechanism B, so that the garbage can better contact the inner wall of the incineration tube, thereby improving the efficiency of removing harmful substances from the garbage. When the volume of the garbage is reduced, the centrifugal component and the material turning component are in a material turning rotating state by controlling the rotating mechanism B, and the small volume of garbage is turned over, so that the garbage is incinerated relatively evenly, thereby further improving the efficiency of removing harmful substances from the garbage. When the harmful substances in the garbage are removed and garbage fly ash is formed, the incineration tube is driven to rotate by the rotating structure A, and the threaded guide groove rotates to assist the discharge of the garbage fly ash, which is independent of the inclination, length and rotation speed of the incineration tube. The rotary kiln incinerator of the present invention is smaller in size than the traditional design, and has a higher efficiency in removing harmful substances from the garbage, thereby solving the technical problem of low efficiency in removing harmful substances by garbage combustion in the current rotary kiln incinerator.

[0033] In the embodiment of the present invention, the rotating mechanism B5 includes a mounting seat 51, which is arranged at the rear side of the incineration tube 31, the mounting seat 51 is fixedly connected to the base 1, a motor 52 is fixedly arranged at the rear end of the mounting seat 51, a rotating chamber 53 is arranged at the head end of the mounting seat 51, the head end of the rotating chamber 53 is rotatably connected to the mounting round block 414, the tail end of the rotating chamber 53 is rotatably connected to the connecting shaft B54, the first output end is composed of the connecting shaft B54, the head end of the connecting shaft B54 is fixedly connected to the mounting round block 414, the tail end of the connecting shaft B54 passes through the mounting seat 51 and is fixedly connected to the output shaft of the motor 52, a reverse rotation component 55 is fixedly arranged on the connecting shaft B54, and a forward rotation component 56 is arranged on the reverse rotation component 55. Through the above arrangement, the present invention can drive the connecting shaft B54 and the mounting round block 414 to rotate by controlling the rotation of the motor 52 through an external control mechanism.

[0034] In an embodiment of the present invention, the reverse rotation component 55 includes a fixed ring 551, which is fixed on the connecting shaft B54. A limit rotation groove 552 is provided on the surface of the fixed ring 551. The depth of the limit rotation groove 552 gradually decreases in the counterclockwise direction. A reverse arc groove 553 is provided on the limit rotation groove 552. Limit chamfers 554 are provided at both ends of the reverse arc groove 553. A limit column A555 is movably connected to the reverse arc groove 553. The limit column A555 is adapted to the shape of the reverse arc groove 553. The limit column A555 is elastically connected to the deep part of the reverse arc groove 553 through a spring A556.

[0035] In an embodiment of the present invention, the forward rotating component 56 includes a limit ring 561, a limit column A555 is movably connected to the inner edge surface of the limit ring 561, the limit ring 561 is rotatably arranged on the limit rotating groove 552, the second output end is composed of the limit ring 561, the surface of the limit ring 561 is annular and evenly spaced structure with a plurality of triangular grooves 562, the depth of the triangular grooves 562 gradually decreases in the clockwise direction, the triangular grooves 562 are movably connected to the limit column B563, the limit column B563 is movably connected to the rotating cavity 53, the limit column B563 is elastically connected to the deep part of the triangular groove 562 by a spring B564, the head end of the limit ring 561 is provided with a material turning guide groove 565, the tail ends of a plurality of rotating rods B423 all pass through the arc groove B415 and are movably connected to the material turning guide groove 565. The present invention adopts the mechanism design of the reverse rotation component 55 and the forward rotation component 56. In the static state, the limit column B563 contacts the triangular groove 562 and the rotating cavity 53 at both ends respectively under the elastic force of the spring B564. When the limit swivel 561 rotates forward, the friction force of the rotating cavity 53 on the limit column B563 enables the limit column B563 to move along the deep part of the triangular groove 562. The resistance of the limit column B563 to the forward rotation of the limit swivel 561 is small. When the limit swivel 561 rotates reversely, the friction force of the rotating cavity 53 on the limit column B563 enables the limit column B563 to move along the deep part of the triangular groove 562. The force of the shallow movement of the triangular groove 562 causes the rotating cavity 53 to lock the triangular groove 562 through the limiting column B563. Therefore, the limiting swivel 561 cannot rotate in the reverse direction. Similarly, the fixed ring 551 can rotate in the reverse direction relative to the limiting swivel 561, and the fixed ring 551 cannot rotate in the forward direction relative to the limiting swivel 561. Therefore, when the connecting shaft B54 rotates in the forward direction, the fixed ring 551 drives the limiting swivel 561 to rotate in the forward direction relative to the rotating cavity 53 as a whole through the limiting column A555. When the connecting shaft B54 rotates in the reverse direction, the fixed ring 551 rotates in the reverse direction relative to the limiting swivel 561, and the limiting swivel 561 does not rotate.

[0036] In an embodiment of the present invention, the material turning guide groove 565 includes a plurality of V-shaped guide grooves 566 arranged in an annular structure with equal spacing, and any two adjacent V-shaped guide grooves 566 are connected. The present invention, through the structural design of the centrifugal material turning mechanism 4 and the rotating mechanism B5, can drive the connecting shaft B54, the mounting block 414, and the limiting swivel 561 to rotate forward when the output shaft of the motor 52 rotates forward, and the centrifugal component 41 and the material turning component 42 rotate forward at the same time, so that when the output shaft of the motor 52 rotates reversely, it can drive the connecting shaft B54 and the mounting block 414 to rotate reversely, and the limiting swivel 561 does not rotate, so that when the centrifugal component 41 and the material turning component 42 rotate reversely, the mounting block 414 and the limiting swivel 561 rotate relative to each other, so that the material turning guide groove 565 and the plurality of arc grooves B41 rotate relative to each other. The gap position changes, so that the rotating rod B423 moves relative to the arc groove B415, and when the rotating rod B423 moves on the two inclined grooves of the V-shaped guide groove 566, the rotating rod B423 moves along the centripetal direction and the eccentric direction of the arc groove B415, so that the arc plate 421 performs a reciprocating rotational material turning action relative to the installation arc groove 413. Only through the bidirectional rotation of the output shaft of the motor 52, the centrifugal material turning mechanism 4 can be driven to perform centrifugal rotational motion and material turning rotational motion, which is convenient to use, saves time and labor, and further solves the technical problem of low efficiency in removing harmful substances by garbage combustion in the current rotary kiln incinerator.

[0037] The method for using the rotary kiln incinerator comprises the following steps: S1: The garbage is fed from the feed pipe 37 into the incineration pipe 31 through the external garbage feeding mechanism. The incineration pipe 31 can be driven to rotate by controlling the rotating structure A2 according to the actual situation to assist the garbage to enter the incineration pipe 31; S2: The output shaft of the motor 52 is controlled to rotate in the forward direction by an external control mechanism, and the centrifugal assembly 41 and the material turning assembly 42 rotate in the forward direction at the same time, so that the garbage can better contact with the inner wall of the incineration tube 31, thereby improving the efficiency of removing harmful substances from the garbage; S3: According to the reduction of the volume of the garbage, the output shaft of the motor 52 can be controlled to rotate in the reverse direction through the external control mechanism, and the rotating rod B423 can move on the V-shaped guide groove 566, so that the rotating rod B423 moves along the eccentric direction of the arc groove B415, so that the arc plate 421 rotates eccentrically to a proper position along the installation arc groove 413, reducing the activity space of the garbage, so that the garbage can better contact with the inner wall of the incineration tube 31, thereby ensuring the efficiency of removing harmful substances from the garbage; S4: When the volume of the garbage is small, the output shaft of the motor 52 is controlled by an external control mechanism to rotate continuously in the reverse direction, so that the rotating rod B423 moves on the V-shaped guide groove 566, and the arc plate 421 performs a reciprocating rotation relative to the arc groove 413 to turn the small volume of garbage, so that the garbage is incinerated relatively evenly, thereby further improving the efficiency of removing harmful substances from the garbage; At the same time, the rotating structure A2 drives the incineration tube 31 to rotate, assisting the turning of small-volume garbage, and the threaded guide groove 32 rotates to assist the discharge of garbage fly ash, and the garbage fly ash after the harmful substances are removed is discharged from the filter plate 34.
