First, the waste is sent into the first crushing unit 112 to preliminarily crush the waste, so as to increase the contact surface area of the waste and improve the efficiency of the subsequent reduction reaction. In some embodiments, the waste includes, but is not limited to, fiber products, food waste, plastic, rubber, glass, ceramics, or incineration ash after incineration and carbonization of items. In one embodiment, a twin shaft crusher may be used for the first crushing unit 112 to reduce the particle diameter of the waste to less than 100 mm.

In some embodiments, the conveying unit 190a to the conveying unit 190j may include, but are not limited to, belt conveying. It is understandable that since the presence of moisture will interfere with the decomposition reaction efficiency during subsequent high temperature heating, Therefore, a water absorbing agent (such as metal oxide, metal hydroxide, metal sulfate, metal sulfide, metal phosphide, or a combination thereof) can be optionally added to any segment on the conveying unit 190a to the conveying unit 190j to be mixed with the waste, The moisture of the waste is initially absorbed, and the odor of the waste is removed at the same time, so as to improve the efficiency of the subsequent reduction and decomposition reaction at high temperature. In some embodiments, when the water absorbing agent is mixed with the waste, the weight percentage of the water absorbing agent may be 1% to 5%, such as 1%, 1.5%, 2%, 2.5%, 3%, 3.5%, 4%, 4.5% %, 5% or any of the aforementioned values, if it is too low, the water absorption effect will be poor. In some embodiments, a water absorbing agent is added to any segment of the conveying units 190a to 190j, for example, the waste is sent from the magnetic separation unit 120 to the segment of the conveying unit 190b of the second crushing unit 114 to enhance the water absorption effect. In some embodiments, the waste can also be preliminarily mixed with the water absorbing agent before the waste is put into the first crushing unit 112 .

Next, the preliminarily crushed waste is sent to the magnetic separation unit 120 . Two sides of the magnetic separation unit 120 are respectively connected to the first crushing unit 112 and the second crushing unit 114 . The magnetic separation unit 120 separates metals in the waste and removes iron to recover directly reusable resources in the waste, thereby improving the efficiency of resource recovery.

Next, the waste is sent to the second crushing unit 114 for further crushing. In some embodiments, considering that the waste has been initially crushed, the second crushing unit 114 may use a single-shaft crusher to further reduce the particle diameter of the waste to less than 5 mm (eg, 2 mm to 3 mm on average).

Next, the waste is sent to the drying unit 130 for further drying. In some embodiments, the dry waste may heat the waste at a temperature above 300°C (including but not limited to 350°C, 400°C, 450°C, or any of the foregoing).

Next, the waste is sent to the crushing unit 116 for further crushing treatment to further reduce the particle diameter of the waste to less than 150 microns, such as 100 microns, 120 microns, 130 microns, 140 microns or any of the foregoing values. between. In some embodiments, a water absorbing agent may be added to the shredding unit 116 such that the weight percentage of water in the waste is less than 5%, such as 1%, 2%, 3%, 4% or any of the foregoing. , to improve the efficiency of subsequent reactions.

Next, the dried and pulverized waste is sent to the storage unit 140 for storage. When the subsequent reaction is to be performed, the waste is sent from the storage unit 140 to the spin drying unit 150 .

The spin drying unit 150 may heat the waste at a temperature higher than 300°C (including but not limited to 350°C, 400°C, 450°C, or any point in between) to dry the waste.

In some embodiments, in order to improve the efficiency of the subsequent reduction reaction, in addition to the inlet and outlet of the waste, the rotary drying unit 150 may be provided with an input port 152 above to facilitate adding other additives, such as catalysts and stabilizers. The role of catalyst and stabilizer is that under the action of high temperature, electromagnetic field or both, the catalyst can catalyze the reduction reaction of waste molecules. As for the stabilizer, it can react with the molecules of waste to generate stable and harmless substances. In some embodiments, the rotating elements inside the rotary drying unit 150 make the waste uniformly mix with the catalyst and the stabilizer to form a mixture, and at the same time, the rotating drying unit 150 is heated above 300°C (including but not limited to 350°C, 400°C, The mixture is heated at a temperature of 450°C, or any of the foregoing values), so that the catalyst and stabilizer can be premixed with the waste and initially reacted. In some embodiments, the catalyst comprises metal oxides, metal hydroxides, metal sulfates, metal sulfides, metal phosphides, or combinations thereof, such as iron oxide ( _{Fe3O4 )} , potassium _oxide (K2O) Aluminum oxide (Al ₂ O ₃ ), calcium oxide (CaO), silicon dioxide (SiO ₂ ), magnesium oxide (MgO), or a combination thereof. In some embodiments, the stabilizer comprises sulfides or other substances that can form stable and safe compounds with waste molecules. In some embodiments, in the mixture of catalyst, stabilizer and waste, the weight percent of catalyst is 3 to 5 percent, the weight percent of stabilizer is 10 to 30 percent, and the weight percent of waste is 70 percent to 80%.

Next, the mixture is sent from the rotary drying unit 150 to the far-infrared processing unit 160 to perform far-infrared and heat treatment. In some embodiments, the mixture can be continuously input into the far-infrared processing unit 160, so that the mixture undergoes decomposition and reduction treatment.

Please refer to FIG. 2 for the configuration of the far-infrared processing unit 160, which includes a reaction area 162 with ceramic materials attached to the inner wall and a heating element 165 disposed on the side of the reaction area 162, wherein the reaction area 162 and the heating element 165 A bracket 166 and a second bracket 168 are supported to stabilize the structure.

The reaction zone 162 includes a first input port 161, a second input port 163 on the side wall, and a discharge port 164 located at the bottom of the reaction zone 162. A connecting channel 167 can also be provided therein for personnel to approach the second input port 163 for temporary input. or small amounts of waste. In some embodiments, the inner wall of the reaction zone 162 is attached with a ceramic material, wherein the ceramic material includes metal oxides, metal carbides, metal silicides, metal borides, metal nitrides, metal elements (eg, aluminum), or combinations thereof . In some embodiments, the ceramic material can be selected from fine ceramics, such as alumina or zirconium-based metals, among which, alumina (especially α-alumina) has better heat resistance and corrosion resistance, and can be used as a relatively Stable ceramic material.

In some embodiments, the heating element 165 may also be positioned directly below the reaction zone 162 . However, compared to disposing the heating element 165 directly under the reaction area 162, disposing the heating element 165 at the side of the reaction area 162 can not only increase the heating height of the reaction area 162, but also increase the actual reaction volume of the far infrared rays, and transmit the far infrared rays through The separation of the reaction zone 162 and the heating element 165 increases the sustainable operation time of the reaction zone 162 .

In some embodiments, the height of the far-infrared processing unit 160 may be higher than 4 meters, for example, 4, 5, 6, 7, 8, 9, 10 meters or any value in the aforementioned range. In one embodiment, the length and width of the reaction zone 162 can be at least 1 meter, such as 1, 2, 3, 4, 5, 6 meters or any value in the aforementioned range, and the height of the reaction zone 162 can be at least 1 meter. 2 meters, such as 2, 3, 4, 5, 6 meters or any of the above Numerical values, however, are not so limited.

The waste or the mixture can be continuously fed into the reaction zone 162 through the first input port 161, and then the heating element 165 is used to heat the reaction zone 162, and the temperature of the reaction zone 162 is controlled not to be higher than 400°C, which can be 100°C to 400°C ( For example, 100°C, 125°C, 150°C, 175°C, 200°C, 225°C, 250°C, 275°C, 300°C, 325°C, 350°C, 375°C, 400°C, or any value in the aforementioned interval), and borrow For example, by closing the reaction zone 162 or closing the reaction zone 162, the outside air is prevented from being circulated, and the reaction zone 162 is controlled to be a deoxidizing condition, which reduces the supply of oxygen and improves the efficiency of the decomposition reaction. In some embodiments, a gas discharge port (not shown) may be provided at the top of the reaction zone 162 to adjust the internal air pressure and discharge the generated gas. In some embodiments, the catalyst and stabilizer may also be pre-injected into the reaction zone 162, or the catalyst and the stabilizer may be coated on the side of the reaction zone 162, and the waste will be uniformly mixed after entering the reaction zone 162, instead of The waste, catalyst and stabilizer are pre-mixed in the spin drying unit 150.

When the reaction zone 162 is heated by the heating element 165 , the ceramics on the inner wall of the reaction zone 162 emit far infrared rays with a wavelength of 2.5 μm to 30 μm. Far-infrared is a kind of electromagnetic wave, which can activate the vibration and collision of molecules, generate heat energy, and then make the waste carry out dry distillation and carbonization reaction. At the same time, the catalyst cooperates to catalyze the waste molecules to accelerate the reduction reaction. It is worth mentioning that when the waste undergoes a reduction reaction, the stabilizer can react with the waste to form stable and harmless substances (such as metal sulfides) together with the molecules of the waste. In addition, the ceramic emits electromagnetic waves, which are generated in the reaction zone 162 Under the action of the electromagnetic field, the organic matter in the waste is also promoted to undergo dry distillation and carbonization reaction, and is decomposed into inorganic matter. Under such a chain-addition reduction reaction, waste molecules can undergo retort carbonization and decompose or resynthesize within a maximum of 3 hours (eg, 1 hour or 2 hours) with a diameter of less than 200 microns (eg, 100 to 150 microns) product of. In addition, after the dry distillation and carbonization reaction occurs in the reaction zone 162, the newly fed waste can undergo the dry distillation and carbonization reaction within a few seconds, and the reaction speed is accelerated as time increases. It is worth mentioning that the thermal energy of the reaction zone 162 can also be recovered to the rotary drying unit 150 to dry the waste.

In some embodiments, the heat exchange unit 170 can receive the thermal energy released by the far-infrared processing unit 160, and convert the thermal energy into electrical energy through the power generating element 172 to provide the generation and application of electrical energy.

In some embodiments, after the reaction is completed, it can be sent to the collection unit 180 for storage, and output from the output port 182 for use when needed.

It can be understood that the aforementioned pulverization and drying steps of waste are aimed at increasing the contact surface area of waste molecules, catalyst and stabilizer in the subsequent reduction reaction, improving the action efficiency, and avoiding the generation of harmful substances. Therefore, those skilled in the art can routinely adjust or change the reaction parameters such as the drying and pulverizing implementation principle, step sequence, times, and equipment according to the type and state of the waste. In addition, the purpose of the magnetic separation unit 120 in FIG. 1 is to sort metals, so it may be reserved or omitted depending on the material source of the waste and the demand for the product.

For example, see FIG. 3 of the present disclosure, which illustrates a waste treatment apparatus 200 in some embodiments of the present disclosure, and Compared with the waste processing device 100 in FIG. 1 , the waste processing device 200 omits the functions of the original first crushing unit 112 , the magnetic separation unit 120 and the second crushing unit 114 , and the interior includes a drying unit 210 and a crushing unit 220 in sequence. , the storage unit 230, the rotary drying unit 240 and the input port 242, the far infrared processing unit 250, the collection unit 270 and the output port 272, the heat exchange unit 260, the power generation element 262, and the conveying unit 280a to the conveying unit 280g, it should be understood that , the arrangement and function of each element in the waste treatment device 200 may be the same as or similar to the various elements of the waste treatment device 100 , which will not be repeated here. It is also understandable that a person with ordinary knowledge in the art can select a suitable type of crushing machine based on the type of waste and the desired crushing particle size. ", "grinding unit 116" and "grinding unit 220" may be the same or different from each other.

In some embodiments, the waste to be processed by the waste processing device 200 can be selected as waste with smaller particle size or incineration ash after incineration. If the waste processing device 200 is used to process the incineration ash, The incineration ash can be further reduced to small molecules with smaller particle size or an elemental product, so that the volume of the product can be reduced to 1/3 of the volume of the incineration ash. That is, by using the waste processing apparatus 200 containing fewer components, a reaction effect similar to that of the waste processing apparatus 100 can be obtained.

The contents of the products obtained in one embodiment are analyzed as shown in Table 1. These components can be used as construction or civil engineering materials, land improvement materials, agricultural materials (for example, soil improvement materials or fertilizers, such as P ₂ O ₅ ), catalysts for reduction reactions (eg, metal oxides), and ceramic materials.

Figures 4A and 4B compare the planting effects on pumpkin (Figure 4A) and rice (Figure 4B) with or without products added, respectively, in some embodiments of the present disclosure. On the left is the control group without the product added, and on the right is the experimental group with the product added. As a result, it can be seen that if the products of the present disclosure are added, the growth of agricultural products is significantly better.

In general, the waste treatment device and its treatment method provided in some embodiments of the present disclosure can greatly reduce the volume of waste and convert it into excellent Products of nutritional and economic value, advantageously, the thermal energy of the reaction zone 162 and the products can also be recycled and reused, the heat energy can be recovered for the drying step of the treatment device, and the products can be used as catalysts and ceramics in the present disclosure Material. And solve the problem of high temperature incineration of wastes (generally, the temperature of incinerator burning is at least 800 ℃), high water content and oxygen content, resulting in the destruction of the elemental crystals of incineration ash, and the formation of many harmful substances (such as with moisture or Substances generated by the reaction of oxygen), and it is difficult to reuse and even pollute the environment. Therefore, the processing device and the processing method of the present disclosure provide advantageous improvements at least in terms of environmental conservation, resource conservation, and utilization of renewable resources.
