Description

Technical Field

[0001] This invention relates to the field of environmental protection technology, and particularly to the field of harmless treatment technology for ecological toilets, specifically a non-contact heating carbonization incineration device and its usage method. Background Technology

[0002] In the field of environmental protection, the harmless treatment of feces has always been a difficult problem in the harmless treatment of public toilets. Traditional flush toilets have high water consumption and high pollution, requiring septic tanks, sewage pipe networks and sewage treatment plants to receive, transport and treat highly polluted wastewater. At the same time, they also require sludge trucks and sludge treatment plants to remove, transport and treat foul-smelling fecal sludge. All of these inevitably lead to problems such as high investment, high operation and maintenance costs, long construction period, difficulty in site selection and large land occupation.

[0003] Waterless public toilets can solve the above problems to some extent, but they still have some difficulties in cleaning up the waste and cannot completely and thoroughly handle it.

[0004] In summary, how to thoroughly and harmlessly treat feces and reduce the operation and maintenance costs of public toilets is a problem that those skilled in the art are dedicated to solving. Summary of the Invention

[0005] This application provides a carbonization incineration device and its usage method, which uses a non-contact heating carbonization incineration process to harmlessly and resourcefully treat feces on-site, solving the problem of public toilet feces disposal at the terminal, reducing the operation and maintenance costs of public toilets, and improving the environment of public toilets.

[0006] This application provides a carbonization incineration apparatus, comprising:

[0007] A furnace system, the furnace system including a furnace chamber for material combustion;

[0008] A heating and ignition system, located on the furnace chamber system, is used to heat and ignite the material inside the furnace chamber via electromagnetic induction.

[0009] Preferably, the furnace system includes an outer liner and an inner liner, the inner liner being disposed inside the outer liner, and a furnace chamber being formed between the outer liner and the inner liner.

[0010] More preferably, the inner liner is a breathable but waterproof inner liner, and the outer liner is a breathable but waterproof outer liner, so that air can pass through the outer liner and the inner liner to enter the furnace chamber, while the hot water vapor generated during the combustion process cannot pass through the outer liner and the inner liner to escape, thereby achieving heat lock-in.

[0011] Furthermore, the heating and ignition system includes an induction coil and a heating cylinder, wherein the induction coil is wound and fixed around the outer periphery of the outer liner, and the heating cylinder is nested around the outer periphery of the inner liner;

[0012] The heating and ignition system is configured such that when the induction coil is energized, the heating cylinder heats up under the action of electromagnetic induction and ignites the material in the furnace chamber.

[0013] Preferably, the inner liner includes an inner liner lower wall and an inner liner upper wall that are connected to each other, and the outer liner includes an outer liner lower wall and an outer liner upper wall that are connected to each other. The upper wall of the inner liner and the upper wall of the outer liner form a conical furnace chamber main space that is larger at the top and smaller at the bottom. A gap is provided between the lower wall of the inner liner and the lower wall of the outer liner to form an ignition and combustion zone.

[0014] The induction coil is wound and fixed to the outer periphery of the lower wall of the outer liner; the heating cylinder is nested on the outer periphery of the lower wall of the inner liner and is located in the furnace chamber.

[0015] Furthermore, the carbonization incineration device also includes a material stirring system, which includes a rotating shaft connected to a drive device. The rotating shaft is provided with stirring teeth, which are located in the furnace chamber.

[0016] When the rotating shaft is driven by the drive device, it drives the stirring teeth to rotate, stirring the material in the furnace chamber and preventing the material from clumping.

[0017] Preferably, the carbonization incineration device further includes a shell, and the furnace system, heating and ignition system, and material stirring system are all located inside the shell;

[0018] The bottom of the outer casing is provided with an air intake area, and the top of the outer casing is provided with a fan; the top of the furnace system is provided with an air cover;

[0019] The shaft is a hollow shaft, with its bottom extending into the air intake area and its top extending into the lower part of the fan.

[0020] Furthermore, the outer casing is also provided with:

[0021] Exhaust vents are used to discharge the smoke and hot water vapor generated during combustion inside the furnace to the outside of the outer casing; and

[0022] An adjustable flue gas overflow port; the flue gas overflow port is configured to be closed under normal circumstances, and to open as exhaust supplement when the exhaust port exhaust force is insufficient.

[0023] Furthermore, the outer casing is also equipped with a ventilation valve, which is configured as an oxygen supply port inside the furnace chamber.

[0024] This application also provides a carbonization incineration method using the above-mentioned carbonization incineration apparatus, the method comprising the following steps:

[0025] The material to be incinerated enters the furnace chamber, where it is collected, dried, and preheated in the upper part of the furnace chamber before entering the ignition and combustion zone in the lower part of the furnace chamber.

[0026] A high-frequency current is passed through the induction coil to generate an alternating magnetic field, which generates eddy currents on the surface of the heating cylinder, raising the temperature and forming a heating source to heat and ignite the material in the ignition and combustion zone.

[0027] Air enters from the bottom of the outer shell, rises to the outer periphery of the furnace, and enters the furnace chamber through the inner and outer liner to replenish oxygen during combustion. Some air rises to the top of the outer shell through the internal cavity of the hollow rotating shaft. The fan blows the air down along the gap between the air cover and the outer shell to the outer periphery of the furnace, forming an internal convection circulation with the air rising from the bottom, thus enhancing the oxygen supply during combustion.

[0028] The ash from the burned material falls automatically and is discharged at regular intervals.

[0029] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0030] 1. The carbonization incineration device provided in this application carbonizes and incinerates the residues decomposed by microorganisms, such as feces, through a carbonization incineration process, thereby treating the feces harmlessly and resourcefully on-site. This greatly reduces the volume of the residues, shortens the cleaning cycle, and lowers the operating labor costs, enabling the feces to be completely and resourcefully treated on-site, thus solving the problem of public toilet feces treatment at the end point.

[0031] 2. The carbonization and incineration device provided in this embodiment uses a non-contact heating process to heat the material to be processed to a set temperature for carbonization and incineration, with the ash discharged from the equipment. Its ignition process is a non-contact heating method, requiring no open flame, making it convenient to control and safe to operate.

[0032] 3. The carbonization and incineration device provided in this embodiment is designed with a hollow rotating shaft, which allows the bottom air intake part to rise to the top of the furnace.

[0044] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0045] Figures 1-8 The diagram and schematic diagram of the carbonization and incineration device provided in this embodiment are shown. The carbonization and incineration device includes a shell 1, a bushing 2, an induction coil 3, a heating cylinder 4, an outer liner 5, an inner liner 6, a rotating shaft 7, stirring teeth 8, a cover 9, an inner cover 10, a motor 11, a first gear 12, a fan 13, an outer cover 14, a fan shroud 15, a second gear 16, a feed inlet 17, an exhaust pipe 18, a drain valve 19, an ash outlet 20, a mounting base 21, a tee 22, an air exchange valve 23, a cable connector 24, and other components.

[0046] The outer shell 1 is the outer wall of the carbonization and incineration device. Inside the outer shell 1 are a furnace system, a heating and ignition system, and a material stirring system. The outer shell 1 protects the furnace system, heating and ignition system, and material stirring system inside the device.

[0047] Specifically, the furnace system includes an outer liner 5 and an inner liner 6. The inner liner 6 is coaxially disposed inside the outer liner 5, and the furnace chamber of the main furnace body is formed between the outer liner 5 and the inner liner 6. The main furnace chamber is conical, with the upper space of the furnace chamber serving as a material collection, drying, and preheating zone, and the lower space serving as an ignition and combustion zone, used to ignite and burn the material in the furnace chamber through an ignition system.

[0048] In a preferred embodiment, the inner liner 6 includes a lower inner liner wall 61 and an upper inner liner wall 62 connected to each other. The lower inner liner wall 61 is vertically arranged, and the upper inner liner wall 62 is inclined relative to the lower inner liner wall 61 toward the central axis of the outer shell 1.

[0049] The outer liner 5 includes a lower outer liner wall 51 and an upper outer liner wall 52 that are connected to each other. The lower outer liner wall 51 is vertically arranged, and the upper outer liner wall 52 is inclined relative to the lower outer liner wall 51 toward the inner wall of the outer shell 1.

[0050] A gap is provided between the lower wall 61 of the inner liner and the lower wall 51 of the outer liner to form an annular ignition and combustion zone. The upper wall 62 of the inner liner and the upper wall 52 of the outer liner form a conical main space of the furnace chamber, which is larger at the top and smaller at the bottom.

[0051] The height of the upper wall 62 of the inner liner is less than the height of the upper wall 52 of the outer liner. In one optional embodiment, the height of the upper wall 62 of the inner liner is approximately half the height of the upper wall 52 of the outer liner.

[0052] The main body of the furnace chamber is conical to prevent material bridging and accumulation. The upper space of the furnace chamber is the material collection, drying, and preheating zone A, and the lower space is the ignition and combustion zone B. The combustion heat energy in the lower space dries and preheats the material in the upper space for incineration. After the material is ignited in the ignition and combustion zone, it is burned, and the ash falls automatically.

[0053] Furthermore, the lower part of the furnace chamber is provided with an ash accumulation area 26, and an ash outlet 20 is provided on the outer shell 1. The ash outlet 20 extends to the ash accumulation area 26 at the bottom of the furnace chamber, and is used to discharge the ash after combustion in the furnace chamber.

[0054] In a preferred embodiment, the inner liner 6 and the outer liner 5 are made of a breathable but waterproof material, which can fully ensure the supply of oxygen during the combustion process and lock in heat.

[0055] The bottom of the outer shell 1 is provided with an air inlet area 27, which is located below the ash accumulation area 26. A channel for gas to rise is provided between the ash accumulation area 26 and the outer shell 1. Gas enters from the bottom of the outer shell 1 and rises to the outer periphery of the furnace chamber. Because the inner liner 6 and the outer liner 5 are made of breathable but waterproof materials, gas can pass through the inner liner 6 and the outer liner 5 into the furnace chamber, thus replenishing oxygen during combustion. An oxygen replenishment zone C is formed between the furnace chamber and the outer shell 1. Furthermore, the hot water vapor generated during combustion cannot escape through the inner liner 6 and the outer liner 5; the heat is locked inside the furnace chamber.

[0056] The heating and ignition system includes an induction coil 3 and a heating cylinder 4. The induction coil 3 is a spiral ring and is wound and fixed at the lower end of the outer liner 5, located on the outer periphery of the lower wall 51 of the outer liner. The heating cylinder 4 is cylindrical and is nested at the lower end of the inner liner 6, located on the outer periphery of the lower wall 61 of the inner liner, i.e., located in the furnace chamber.

[0057] During operation, an induced current flows through the induction coil 3, forming an alternating magnetic field with the same frequency as the current around it. Through electromagnetic induction, an induced electromotive force is generated in the heating cylinder 4, thereby generating an induced current. Electrical energy is converted into heat energy, which ultimately heats the heating cylinder 4. Through heat conduction, the material in the ignition space between the lower wall 61 of the inner liner and the lower wall 51 of the outer liner is ignited, realizing non-contact heating, which is convenient and safe to control.

[0058] The material mixing system includes a rotating shaft 7, a bushing 2, mixing teeth 8, a motor 11, a first gear 12, a fan 13, and a second gear 16.

[0059] The rotating shaft 7 is located on the central axis of the outer shell 1 and passes through the furnace chamber axially. A bushing 2 is provided at the upper and lower ends of the rotating shaft 7. The bushing 2 provides fixed support for the rotating shaft 7. The bushings 2 at the upper and lower ends are concentrically arranged, and the rotating shaft 7 can rotate within the bushing 2.

[0060] The upper end of the rotating shaft 7 is connected to a gear set, which is connected to the motor 11. Both the gear set and the motor 11 are located in the upper part of the furnace chamber. The middle part of the rotating shaft 7 is connected to stirring teeth 8, which are located inside.

[0061] The motor 11 rotates, which drives the rotating shaft 7 to rotate inside the bushing 2 through the gear set, thereby driving the stirring teeth 8 to rotate, stirring the material in the furnace chamber and preventing the material from clumping.

[0062] In a preferred embodiment, the gear set includes a first gear 12 and a second gear 16 that mesh with each other, the second gear 16 being fixed to the upper end of the rotating shaft 7, and the first gear 12 being connected to the motor 11.

[0063] In a preferred embodiment, the top of the outer casing 1 is further provided with an outer cover 14 to seal the top of the outer casing 1. The top of the outer liner 5 is provided with an inner cover 10, and a vent cover 15 is provided above the inner cover 10, located below the outer cover 14. A smoke-free drive space is formed between the inner cover 10 and the vent cover 15, and the motor 11 and gear set are both located within the drive space, with the motor 11 mounted on the inner cover 10.

[0064] The rotating shaft 7 is a hollow shaft. The bottom of the rotating shaft 7 extends through the dust accumulation area 26 into the air intake area 27, and the top of the rotating shaft 7 extends through the inner cover 10 to the bottom of the air cover 15.

[0065] A fan 13 is located at the top center of the outer cover 14. The fan 13 is located inside the outer casing 1 and above the fan cover 15. An air outlet is provided on the fan cover 15 corresponding to the fan 13. The fan 13 is coaxially arranged with the rotating shaft 7.

[0066] Air in the intake zone 27 rises through the internal cavity of the hollow rotating shaft 7 to the top of the outer casing 1, where it is drawn out by the fan 13. The presence of the air cover 15 prevents the air drawn out by the fan 13 from directly entering the furnace chamber from the top; instead, it flows downwards along the gap between the air cover 15 and the outer casing 1 to the outer periphery of the furnace chamber, forming an internal convection circulation with the rising air at the bottom to supply oxygen for combustion. Through the action of the fan 13, a fresh air circulation zone D is formed at the top of the outer casing 1.

[0067] Furthermore, the upper part of the outer shell 1 is also provided with a feed inlet 17 for feeding the material to be incinerated into the furnace chamber. The feed inlet 17 passes through the upper wall 52 of the outer shell and extends to the upper part of the furnace chamber.

[0068] Furthermore, the upper part of the outer shell 1 is also provided with an exhaust port 25, which is connected to the exhaust pipe 18 outside the outer shell 1, and is used to discharge the smoke and hot water vapor generated during combustion in the furnace chamber to the outside of the outer shell 1 in a timely manner.

[0069] The exhaust pipe 18 is equipped with a drain valve 19 at the bottom, which is used to discharge the condensate formed after the water vapor is cooled.

[0070] In a preferred embodiment, the lower end of the exhaust pipe 18 is also provided with a tee 22, which is located above the drain valve 19 and serves as a condensate recovery port that can be connected to a condensate recovery device.

[0071] Furthermore, the upper part of the outer shell 1 is provided with a flue gas overflow port 28, and an outer cover 9 is provided on the flue gas overflow port 28. The upper part of the outer liner 5 is also provided with an opening corresponding to the flue gas overflow port 28. Under normal circumstances, the outer cover 9 is closed on the flue gas overflow port 28; when the exhaust port 25 is insufficient, the outer cover 9 is opened, and part of the flue gas is discharged through the flue gas overflow port 28 as exhaust supplement.

[0072] Furthermore, the outer wall of the outer shell 1 is also provided with a mounting base 21, which is used for installation and fixation to realize the installation and fixation of the entire carbonization and incineration device.

[0073] Furthermore, the outer cover 14 is also provided with an air exchange valve 23, which serves as an oxygen supply port inside the furnace chamber.

[0074] Furthermore, the outer cover 14 is also provided with a cable connector 24, which is a cable introduction device. The cable connector 24 connects the motor 11 and the power supply induction coil 3 through wires and is used to supply power to the motor 11 and the power supply induction coil 3.

[0075] The specific operating method of the above-mentioned carbonization and incineration device is as follows:

[0076] The material to be incinerated enters the furnace chamber through the feed inlet 17. The material is collected, dried and preheated in the upper space of the furnace chamber, and then enters the ignition and combustion zone of the furnace chamber.

[0077] A high-frequency current is passed through the induction coil 3 to generate a rapidly changing alternating magnetic field. Eddy currents are generated on the surface of the heating cylinder 4, and the temperature rises, forming an ignition heating source to ignite the material in the ignition and combustion zone.

[0078] Air enters from the air intake area 27 at the bottom of the outer shell 1 and rises to the outer periphery of the furnace. Since the inner liner 6 and the outer liner 5 are made of breathable but waterproof materials, air can pass through the inner liner 6 and the outer liner 5 to enter the furnace chamber, thereby replenishing oxygen during the combustion process.

[0079] Part of the air in the intake zone 27 also rises to the top of the outer shell 1 through the internal cavity of the hollow rotating shaft 7. The fan 13 blows the air down to the outer periphery of the furnace through the gap between the air cover 15 and the outer shell 1, forming an internal air convection circulation with the air rising from the bottom, thus enhancing the oxygen supply during combustion. If necessary, air can also be supplemented through the air exchange valve 23. Similarly, air enters the top of the outer shell 1 through the air exchange valve 23, and the fan 13 blows the air down through the gap between the air cover 15 and the outer shell 1.

[0080] The ash from the burned material automatically falls into the ash accumulation area 26, and the ash is discharged from the ash outlet 27 at regular intervals.

[0081] The smoke and hot water vapor generated during combustion in the furnace chamber are promptly discharged to the outside of the outer casing 1 through the exhaust pipe 18. When the exhaust port 25 is insufficient, the outer cover 9 is opened, and part of the flue gas is discharged through the flue gas overflow port 28 as exhaust supplement.

[0082] The material to be incinerated is usually the residue from microbial decomposition, such as feces.

[0083] The carbonization and incineration device provided in this embodiment uses a non-contact heating process to heat the material to be processed to a set temperature for carbonization and incineration, with the ash discharged from the equipment. Its ignition process is a non-contact heating method, requiring no open flame, making it convenient to control and safe to operate.

[0084] The carbonization incineration device provided in this embodiment is particularly suitable for the treatment of feces from public toilets. Through the carbonization incineration process, feces are treated on-site in a harmless and resource-efficient manner, solving the problem of public toilet feces disposal at the end point.
