Description

Technical Field

[0002] Domestic waste mainly includes household waste, market trade and commercial waste, public place waste, street cleaning waste and waste from enterprises and institutions. In order to achieve the reduction, harmlessness and resource utilization of domestic waste, it is usually necessary to incinerate domestic waste.

[0003] Domestic waste burns in an incinerator to generate heat, slag and fly ash. Fly ash has both heavy metal hazard characteristics and persistent organic pollutant hazard characteristics. Incineration fly ash contains high concentrations of heavy metal ions that are easily leached by water, as well as dioxins and furans that are highly harmful. These pollutants will pollute water bodies and soil, and then endanger the health of animals, plants and humans. Therefore, the fly ash needs to be solidified. The solidified fly ash becomes a pre-burned block of a specific shape, which is then incinerated to turn the pre-burned block into a prefabricated block (i.e., a crystalline compound) to facilitate the reuse of the prefabricated block.

[0004] However, in the existing domestic waste treatment system, the sintering incinerators used for fly ash sintering directly pile the pre-burned blocks on the grate in the sintering incinerator. A large number of pre-burned blocks piled on the grate may cause uneven burning of the pre-burned blocks, and some pre-burned blocks cannot be completely burned. After the incineration is completed, some pre-burned blocks need to be burned for the second time, which reduces the incineration efficiency. Summary of the invention

DETAILED DESCRIPTION

[0020] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content. Embodiment 1

[0021] like Figure 1 , Figure 2 As shown, a domestic waste kernel sintering incinerator comprises a furnace body 1, a grate 4 is installed at the inner bottom of the furnace body 1, a circulating incineration mechanism 3 is arranged above the grate 4, a material delivery port is opened on the surface of the furnace body 1, and a feeding mechanism is installed at the material delivery port; The circulating combustion mechanism 3 includes two sets of rotating gears 35 and chains 31 sleeved on the two sets of rotating gears 35. The two sets of rotating gears 35 are rotatably connected to the inner wall of the furnace body 1. Multiple sets of conveying plates 32 are installed on the chains 31. The feeding mechanism conveys the pre-burned blocks to the conveying plates 32. The furnace body 1 is connected to a driving mechanism 6. The driving mechanism 6 drives the rotating gears 35 to rotate, thereby driving the pre-burned blocks on the multiple sets of conveying plates 32 to pass through the combustion zone of the grate 4 in sequence at a uniform speed. The circulating incineration mechanism 3 also includes a sliding member 34. A limiting slide rail 33 is provided on the inner wall of the furnace body 1. The sliding member 34 moves along the surface of the limiting slide rail 33. The sliding member 34 is fixedly connected to one side of the conveying plate 32. The limiting slide rail 33 cooperates with the sliding member 34 to keep the conveying plate 32 in a horizontal state at all times.

[0022] Specifically, a collecting box 5 is provided on one side of the furnace body 1 for collecting the pre-burned blocks after incineration. The collecting box 5 is located at the end of the conveying direction of the grate 4. In this embodiment, the grate 4 is a chain grate for conveying the pre-burned blocks after incineration.

[0023] It should be noted that the feed port is arranged near the upper end of the chain 31. Through this arrangement, the pre-burned blocks will not directly enter the combustion zone of the grate 4 when entering the furnace body 1, so the pre-burned blocks can be preheated, and the circulating incineration mechanism 3 can make the pre-burned blocks burn more evenly, thereby improving the incineration efficiency and eliminating the need for secondary incineration.

[0024] It should be further explained that the driving mechanism 6 can be a servo motor, a stepping motor, etc.

[0025] Furthermore, the furnace body 1 includes a side wall 101 and a blocking wall 102, the blocking wall 102 is located inside the furnace body 1 and fixedly connected to the surface of the side wall 101, the blocking wall 102 is hollow inside, the limiting slide rail 33 is opened on the inner wall of the blocking wall 102, and the rotating gear 35 is rotatably connected to the inner wall of the blocking wall 102.

[0026] It should be noted that the blocking walls 102 can be provided in multiple groups and can be arranged in a linear array along the conveying direction of the grate 4. The multiple groups of blocking walls 102 divide the space in the furnace body 1, and each group of separated spaces is correspondingly provided with a circulating incineration mechanism 3 and a feeding mechanism.

[0027] It should be further explained that, when multiple groups of circulating incineration mechanisms 3 are provided, the rotating gears 35 on the same side of the multiple groups of circulating incineration mechanisms 3 are coaxially connected and commonly connected to the driving end of the driving mechanism 6 .

[0028] Furthermore, a plurality of incineration holes are provided on the surface of the conveying plate 32 .

[0029] Furthermore, connecting rods are fixedly connected on both corresponding sides of the conveying plate 32. The connecting rod on the side of the conveying plate 32 close to the chain 31 passes through the chain 31 and is fixedly connected to the sliding member 34. A slide groove 1 is provided on the side of the inner wall of the furnace body 1 away from the chain 31, and the connecting rod on the side of the conveying plate 32 away from the chain 31 extends into the slide groove 1.

[0030] Specifically, the connecting rod close to one side of the chain 31 is cylindrical and is inserted through the connection between the inner link plate and the outer link plate on the chain 31 .

[0031] It should be noted that the connecting rod on the side of the conveying plate 32 away from the chain 31 cooperates with the slide groove 1 to make the conveying plate 32 move more stably, and the side connecting rod can be set in a style that is embedded with the slide groove 1.

[0032] Furthermore, the sliding member 34 includes a cross connecting plate 345 and four groups of rollers, and the four groups of rollers are respectively rotatably connected to the side surface of the cross connecting plate 345 away from the conveying plate 32 and close to the end of the cross connecting plate 345. The limiting slide rail 33 includes four groups of running tracks, and the four groups of rollers slide according to the four groups of running tracks respectively.

[0033] Specifically, the four groups of rollers include roller 1 341, roller 2 342, roller 3 343 and roller 4 344, and the four groups of running tracks of the restricted track are as follows: Figure 4 As shown by the dotted line in FIG. 1 , the roller 1 341 corresponds to Figure 4 In the running track of (a), roller 2 342 corresponds to Figure 4 In the running track of (b), roller 343 corresponds to Figure 4 In the running track of (c), roller 4 344 corresponds to Figure 4 The running trajectory of (d).

[0034] Furthermore, the feeding mechanism includes a pushing component 7 and a conveyor belt, wherein the pushing component 7 is connected to the furnace body 1 , and the conveyor belt transports the pre-burned blocks to one end close to the pushing component 7 , and the pushing component 7 pushes the pre-burned blocks to the upper surface of the conveying plate 32 .

[0035] It should be noted that the solidification of fly ash is as follows: a solidifying agent is used to mix the fly ash, and then the mixed fly ash is pressed by a pressing mechanism to form a pre-burned block; In this embodiment, the pressing mechanism is arranged at one end of the conveyor belt away from the pushing component 7, and it presses the stirred fly ash through a mold to press it into a rectangle. The pressing side of the mold (i.e., the side that presses the fly ash) is in a grid shape, and the formed fly ash (i.e., the pre-burned block) is arranged in a rectangular array and pushed onto the conveyor belt (here, a pushing plate consistent with the shape of the mold can be used to push the pre-burned block onto the conveyor belt), wherein the pressing mechanism can be any existing machine that can press the fly ash that has been added with a curing agent and stirred into a pre-burned block.

[0036] Furthermore, the pushing mechanism includes a pushing frame 71, a driving block 72, a pushing block 73, a baffle 74 and a driving component 2, the baffle 74 is fixedly connected to the inner wall of the furnace body 1, the driving component 2 drives the pushing block 73 to slide along the inner wall of the furnace body 1 (including the side surface of the side wall 101 close to the blocking wall 102 and the blocking wall 102), the driving block 72 is slidably connected to the surface of the pushing block 73, the pushing frame 71 is slidably connected to the lower surface of the driving block 72, the inner wall of the furnace body 1 is provided with a second slide groove 75 and a third slide groove 76, the surfaces of the driving block 72 and the pushing frame 71 are respectively fixedly connected with a second slider 77 and a third slider 78, the second slider 77 and the third slider 78 slide along the inner walls of the second slide groove 75 and the third slide groove 76 respectively, and the pushing block 73 is connected to the driving end of the driving component 2.

[0037] Specifically, the push frame 71 is consistent with the shape of the mold. By pushing the pre-burned blocks through the push frame 71 of this shape, there can be gaps between each group of pre-burned blocks when the pre-burned blocks are moved onto the conveying plate 32, so that they can be burned more thoroughly and evenly.

[0038] It should be noted that the second slider 77 cooperates with the second slide groove 75 to control the movement of the driving block 72 , and the third slider 78 and the third slide groove 76 cooperate to control the movement of the push frame 71 .

[0039] Specifically, the second slide groove 75 includes a straight segment 1, an oblique segment 1, a straight segment 2, an oblique segment 2, and a vertical segment 1 connected in sequence. The overall shape of the second slide groove 75 is similar to a parallelogram, and the shape of the third slide groove 76 is a rectangle.

[0040] In actual use, when the driving component 2 drives the push block 73 to move so that the push frame 71 contacts the surface of the baffle 74, the push block 73 continues to move (at this time, the push frame 71 cannot move horizontally), so that the slider 2 77 moves to a place in the inclined section. The inclined section 1 cooperates with the slider 2 77 to make the driving block 72 drive the push frame 71 to move upward. At the same time, the driving block 72 will also slide along the upper surface of the push frame 71. When the driving component 2 drives the push block 73 to perform a reciprocating motion, it will drive the push frame 71 to move a complete rectangular trajectory.

[0041] Furthermore, a slot 8 is provided on the inner wall of the slide slot 3 76 close to the push frame 71, and a bevel block 9 is slidably connected in the slot 8. A compression spring 10 is connected to one side of the bevel block 9 located in the slot 8, and one end of the compression spring 10 is fixedly connected to the inner wall of the slot 8.

[0042] It should be noted that when the slider three 78 moves to the inclined block 9, the inclined block 9 will be pushed into the slot 8. When the slider three 78 continues to move, the inclined block 9 will pop out of the slot 8. Only then can the drive assembly 2 be started to move the push frame 71 in the direction of the conveyor belt. The cooperation between the inclined block 9 and the compression spring 10 can prevent the slider three 78 from reversing.

[0043] Furthermore, the driving assembly 2 includes a motor 201 and a screw rod 202 , the screw rod 202 is fixedly connected to the driving end of the motor 201 , the motor 201 is connected to the furnace body 1 , and the push block 73 is threadedly connected to the screw rod 202 .

[0044] It should be noted that the motor 201 is a servo motor, a stepping motor, or the like.

[0045] It should be further explained that a driving member can be connected to the outer surface of the furnace body 1, and the driving end of the driving member extends into the furnace body 1 and is connected to a push plate. After the pre-burned blocks are burned on the conveying plate 32, the driving member can be used to drive the push plate to push the burned prefabricated blocks on the conveying plate 32 onto the grate 4, and the burned pre-burned blocks are transported to the collection box 5 by the grate 4. Embodiment 2

[0046] This embodiment provides a method for incinerating domestic waste, which can be used in the sintering incinerator provided in the first embodiment, comprising the following steps: S1. Put the pretreated garbage into the garbage incinerator to carry out pyrolysis and combustion reaction under high temperature environment; S2. Collect slag and fly ash produced during waste incineration; S3. Add a curing agent to the collected fly ash and stir it thoroughly; S4. The mixed fly ash is pressed into pre-burnt blocks using a lamination wrapping technique.

[0047] S5. The pre-burned block is transported to a sintering furnace through a feeding mechanism to form a crystalline compound.

[0048] It should be noted that the pretreatment in step S1 includes: 1) Sorting: Through sorting, high-value recyclable items (such as metals, plastics, etc.) can be separated for resale or reuse, reducing the total amount of garbage and improving incineration efficiency. Sorting work is usually carried out during the garbage collection stage and requires the cooperation of residents and sanitation workers. 12; 2) Crushing: Crushing garbage into smaller particles. Crushed garbage is easier to burn, which can improve incineration efficiency. Crushing equipment usually uses mechanical crushers, such as shear crushers, hammer crushers, etc. During the crushing process, it is necessary to pay attention to controlling the particle size to avoid particles that are too large or too small affecting the incineration effect; 3) Drying: Reduce garbage Moisture content: garbage with too high moisture content will consume a lot of heat energy during the incineration process, reducing the incineration efficiency. Drying equipment usually uses hot air dryers or solar dryers; 4) Compression: compress the garbage into a tighter volume to reduce the floor space of the incinerator and the flue gas emissions during the incineration process. The compression process usually uses mechanical compressors, such as screw compressors, hydraulic compressors, etc.; 5) Removal of incombustible substances: Before incineration, it is necessary to remove incombustible substances in the garbage, such as metals, glass, ceramics, etc. These substances will not burn during the incineration process, which will increase the amount of slag and reduce the incineration efficiency. Methods for removing incombustible substances include magnetic separation, air separation, screening, etc. It should be further explained that the lamination wrapping technology is to combine multiple layers of the same or different materials into a whole by heating and pressurizing.

[0049] The present invention adopts an in-situ high-temperature solidification method to crystallize and solidify fly ash, solidify heavy metals in the crystal structure, and at the same time, digest organic hazards such as dioxins by high temperature. The fly ash of the power plant is collected into a specific fly ash storage tank through a fully closed system, and then the fly ash is pumped into the processing equipment. During the production process, K-type, Y-type, and B-type curing agents are added in proportion, fully stirred, layered, granulated, and combined with the fly ash. Through Duan's layered material distribution and lamination packaging technology, it is pressed into a pre-burned block. After the pre-burned block is specially designed in shape (circular, rectangular, etc.), it is transported through a conveying system. After being transported to the sintering incinerator, the fly ash reacts with the curing agent under high temperature to form new crystalline compounds. The curing agent forms hollow spheres under high temperature, wraps the heavy metal ions in the spheres, and finally reacts into stable compounds that are insoluble in water. At the same time, dioxins and furans are decomposed into non-toxic gases such as carbon dioxide and water under high temperature. After treatment, the prefabricated blocks have been vitrified, and the heavy metals are firmly solidified in them to form stable compounds. The sintered prefabricated blocks (crystalline compounds) are sent to recycling agencies together with the slag, and eventually become aggregates for building materials, completing resource utilization.

[0050] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
