[0033] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0034] Example 1:

[0035] The utility model provides a skid-mounted medical hazardous waste pyrolysis carbonization device, Figures 1 to 3 As shown, the skid-mounted medical hazardous waste pyrolysis and carbonization device includes a storage box 1, a dry distillation and pyrolysis device 2 and a conveying device 3.

[0036] The storage box 1 is used for storing hazardous medical waste.

[0037] The dry distillation and pyrolysis device 2 pyrolyzes medical hazardous waste in an anaerobic or anoxic environment. The dry distillation and pyrolysis device 2 includes a preheating chamber 21, a pyrolysis chamber 22 and a cooling chamber 23 arranged in sequence; the conveying device 3 is arranged in the dry distillation and pyrolysis device 2, and can convey the storage box 1 from the preheating chamber 21 to the pyrolysis chamber 22 and the cooling chamber 23 in sequence. The preheating chamber 21 is provided with a loading door, and the cooling chamber 23 is provided with a unloading door.

[0038] When handling hazardous medical waste, place the hazardous medical waste in a storage box, open the loading door, and transfer the storage box 1 to the starting end of the conveying device 3 by a hoist or forklift. Close the loading door, and the hazardous medical waste is preheated in the preheating chamber 21. Then the conveying device 3 transports the storage box to the pyrolysis chamber 22, and then to the cooling chamber 23. After cooling is completed, open the unloading door and take out the storage box 1.

[0039] During the above process, the preheating chamber 21, the pyrolysis chamber 22 and the cooling chamber 23 are filled with inert gas for protection.

[0040] Medical hazardous waste is dehydrated, decomposed, pyrolyzed, condensed and carbonized under anaerobic or anoxic conditions. In the early stage of the distillation operation, the organic matter in the medical hazardous waste is first dehydrated. As the temperature rises, it gradually decomposes to produce low-molecular volatiles. As the distillation temperature continues to rise, the bonds in the large molecules in the organic matter break, that is, pyrolysis occurs, and liquid organic matter (including plastic oil) is obtained. When the temperature is further increased, as water and organic vapor are precipitated, the remaining substances are condensed into colloids by heat. At the same time, the volatiles precipitated gradually decrease, and the colloid gradually solidifies and carbonizes. In this process, different products will be produced depending on the raw materials, such as waste plastics, waste rubber, waste paper, waste wood, waste tar, waste organic tissue, etc.

[0041] The utility model uses a dry distillation pyrolysis device 2 having a preheating chamber 21, a pyrolysis chamber 22 and a cooling chamber 23. Under anaerobic or anoxic conditions, heat energy is used to break the chemical bonds of compounds, thereby converting large molecular weight organic matter into small molecular weight combustible gas, liquid fuel and carbon. On the one hand, the pyrolysis process is carried out in an anaerobic reducing atmosphere, and no dioxin precursors are generated. Valuable metals such as Cu and Fe in medical waste are not oxidized, and catalysts that promote dioxin generation are not easily generated. In principle, the generation of dioxins is blocked, and nitrogen oxides (NOx) are reduced during the treatment process. x ), the production and emission of sulfur dioxide (SO2) and carbon dioxide (CO2). On the other hand, the solidified and carbonized products can be recycled and reused.

[0042] The utility model can fully realize the harmless treatment of medical hazardous waste and the recycling of resources, thereby reducing the harm caused to the environment to the greatest extent.

[0043] Example 2:

[0044] Example 2 is based on Example 1:

[0045] like Figures 1 to 10 As shown, an isolation door can be opened and closed between the preheating chamber 21 and the pyrolysis chamber 22; an isolation door can be opened and closed between the pyrolysis chamber 22 and the cooling chamber 23; in this way, the preheating chamber 21, the pyrolysis chamber 22 and the cooling chamber 23 can form relatively independent chambers.

[0046] Optionally, the isolation door adopts an existing gravity-type inclined closed door.

[0047] The conveying device 3 adopts a step-by-step conveying device, specifically, it is set as a three-section step-by-step conveying chain device, including three sections of conveying chains, which are respectively arranged in the preheating chamber 21, the pyrolysis chamber 22 and the cooling chamber 23. The two adjacent conveying chains cooperate with each other to complete the conveying transition between the chambers.

[0048] During actual application, the preheating chamber 21, the pyrolysis chamber 22 and the cooling chamber 23 are used to set parameters such as the pyrolysis temperature, pyrolysis time and pyrolysis speed according to the actual characteristics such as the melting point temperature of the medical hazardous waste to be processed, so that the medical hazardous waste enters the preheating chamber 21, the pyrolysis chamber 22 and the cooling chamber 23 in sequence and step by step to complete the pyrolysis.

[0049] As an optional embodiment, a first spray device 24, a second spray device 25 and a third spray device 26 are respectively provided in the preheating chamber 21, the pyrolysis chamber 22 and the cooling chamber 23. The first spray device 24, the second spray device 25 and the third spray device 26 are used for cooling and dust removal of the corresponding chambers.

[0050] Since the temperature of the pyrolysis chamber 22 is relatively high, the water sprayed from the second spraying device 25 forms superheated steam, which also serves as a protective gas.

[0051] The third spraying device 26 is an alkaline solution spraying device, which also has the function of neutralizing or removing acidic gases.

[0052] As an optional embodiment, the skid-mounted medical hazardous waste pyrolysis and carbonization device includes a flue gas treatment device 4 , and the flue gas inlet pipe of the flue gas treatment device 4 is connected to the dry distillation and pyrolysis device 2 .

[0053] The flue gas treatment device 4 can effectively treat the waste gas generated after the pyrolysis of medical hazardous waste, and on the basis of effectively reducing the emission of pollutants, it can also realize the recycling of resources.

[0054] As an optional embodiment, the flue gas treatment device 4 includes a device body 41 and a cooling unit 42 . The device body 41 is configured as a cabinet, and the cooling unit 42 is disposed inside the device body 41 .

[0055] A heat exchange chamber is provided in the device body 41, and the flue gas inlet pipe is connected to the heat exchange chamber. The cooling unit 42 includes a cooling spray mechanism 421 and a liquid cooling mechanism 422. The cooling spray mechanism 421 is arranged above the liquid cooling mechanism 422, and the liquid cooling mechanism 422 is arranged in the heat exchange chamber.

[0056] When the exhaust gas enters the heat exchange chamber, the cooling spray mechanism 421 sprays water, and at the same time the liquid cooling mechanism 422 operates to perform heat exchange with the exhaust gas, thereby effectively reducing the temperature of the exhaust gas. The condensable gas in the exhaust gas dissolves in the water and moves downward, while the non-condensable gas moves upward.

[0057] Optionally, the liquid cooling mechanism 422 includes a plurality of heat exchange tubes, the liquid inlets and liquid outlets of which are respectively arranged on the outside of the device body 41 .

[0058] As an optional embodiment, the flue gas treatment device 4 includes a water filter unit 43 and an oil-water separation unit 44 . The water filter unit 43 is arranged below the liquid cooling mechanism 422 , and the oil-water separation unit 44 is arranged below the water filter unit 43 .

[0059] The oil-water separation unit 44 includes an oil-water separation tank, an oil storage tank and a mud storage tank. The oil-water separation tank is located above the oil storage tank and the mud storage tank. The oil-water separation tank is provided with an overflow pipe, which is connected to the oil storage tank. A mud connecting pipe is provided at the bottom of the oil-water separation tank, which is connected to the mud storage tank. Drain pipes are provided on the lower part of the side wall of the oil-water separation tank and the upper part of the side wall of the mud storage tank.

[0060] During oil-water separation, the plastic oil in the oil-water separation box is located in the upper layer, and the overflow pipe overflows into the oil storage tank for secondary utilization.

[0061] As an optional embodiment, the flue gas treatment device 4 includes a graphite fiber filter unit 45 and a plasma purification unit 46 .

[0062] The graphite fiber filter unit 45 is arranged in the device body 41 and is located above the cooling spray mechanism 421. A flue gas exhaust pipe is provided on the top of the device body 41. Non-condensable gas is filtered by the graphite fiber filter unit 45 and then discharged through the flue gas exhaust pipe.

[0063] The graphite fiber filter unit 45 includes a filter box, a gas expansion chamber 451 is provided in the filter box, a layered graphite fiber is provided in the filter box, a spray pipe 452 is provided above the graphite fiber, an overflow port 453 is provided at the bottom of the filter box, and a maintenance port 454 is provided on the side wall of the filter box. The maintenance port 454 is used to regularly replace the saturated graphite fiber.

[0064] The layered graphite fibers can form tiny gaps between the fibers, which can be used to filter impurities and effectively prevent damage to the pipeline system caused by corrosive substances (gas, water) after filtration.

[0065] The filtering effect of graphite fiber is mainly reflected in the following aspects:

[0066] (1) Good mechanical strength and thermal stability: Graphite fiber has excellent mechanical strength and thermal stability. It will not break due to temperature changes or mechanical stress, thereby maintaining the stability of its filtration performance and will not cause alkali metal poisoning.

[0067] (2) Chemical stability: Graphite fiber also has good chemical stability and can maintain the stability of its structure and performance in various chemical environments. This is especially important for filtration applications that need to withstand different composition conditions. There will be no failure of filtration functionality caused by scaling on the surface of the filter material.

[0068] (3) The hydrophobicity and relatively thin atomic thickness of graphite fiber can improve filtration efficiency and has a wide range of applications in the field of filtration, including but not limited to water purification and seawater desalination. This can be used as a reference for dust removal and acid gas control in medical waste flue gas with high moisture content.

[0069] The plasma purification unit 46 is arranged on the top side of the dry distillation and pyrolysis device 2 and is connected to the flue gas exhaust pipe; the plasma purification unit 46 can generate ozone, which uses low-temperature plasma to deeply purify dioxins and remove odor from the device.

[0070] Low-temperature plasma technology has unique advantages in treating dioxins, VOCs and deodorization:

[0071] Dioxin is a highly toxic organic substance with carcinogenic and teratogenic properties, which is usually produced during the incineration of medical waste. Low-temperature plasma technology can effectively remove these pollutants. Its mechanism is mainly that high-energy electrons in the plasma react with dioxin molecules, decomposing them into harmless substances.

[0072] As an optional embodiment, the skid-mounted medical hazardous waste pyrolysis and carbonization device includes a high-frequency co-frequency resonant fluid heater 5 for providing heat to the pyrolysis chamber 22, and the inlet pipe 51 and the return pipe 52 of the high-frequency co-frequency resonant fluid heater 5 are both connected to the pyrolysis chamber 22.

[0073] The high-frequency same-frequency resonant fluid heater 5 includes a tube body, a high-frequency electromagnetic heating power supply 54 , a high-frequency coil 55 and a ceramic insulating cylinder 56 , and both the high-frequency coil 55 and the ceramic insulating cylinder 56 are arranged in the tube body.

[0074] The high-frequency electromagnetic heating power supply 54 is electrically connected to the high-frequency coil 55 through a cable. The high-frequency coil 55 is wound around the outside of the ceramic insulating cylinder 56. The section of the ceramic insulating cylinder 56 corresponding to the high-frequency coil 55 forms a high-frequency heating cavity. The ceramic insulating cylinder 56 isolates the high-frequency coil 55 from the outside of the heating flow, which can prevent the coil from aging, avoid the decline of its heat insulation ability, and improve its service life.

[0075] Optionally, the high-frequency same-frequency resonant fluid heater 5 also includes a heat dissipation device, and an annular fresh air cavity is provided in the tube body on the outside of the ceramic insulating cylinder 56, and the annular fresh air cavity is connected to the fresh air pipe 53. The fresh air enters the annular fresh air cavity through the fresh air pipe 53, which can achieve heat dissipation of the high-frequency same-frequency resonant fluid heater 5, and the annular fresh air cavity is connected to the air outlet pipe, and the air outlet pipe is connected to a heat exchanger, and the heat exchanger is connected to the flue gas inlet pipe through a connecting pipe.

[0076] As an optional embodiment, a magnetic fluid device 6 is provided on the return air pipe of the high-frequency synchronous resonant fluid heater 5 . The magnetic fluid device 6 includes a ceramic tube 61 and a permanent magnet ring 62 .

[0077] The number of the permanent magnet rings 62 is set to be multiple, and all the permanent magnet rings 62 are sequentially arranged in the ceramic tube 61 along the axial direction of the ceramic tube 61 , and all the permanent magnet rings 62 form a magnetic fluid channel along the axial direction.

[0078] The magnetic fluid device 6 uses a permanent magnetic field to affect the process of molecular mass transfer in the gas. The permanent magnetic field can change the movement trajectory of the molecules. Because molecules carry electric charges, they will be affected by the magnetic field in the permanent magnetic field, causing the movement trajectory of the molecules to change, which has an impact on the molecular mass transfer process. The permanent magnetic field can affect the interaction between molecules. The interaction between molecules is an important factor in the molecular mass transfer process. By affecting the interaction between molecules, the permanent magnetic field can change the rate of the molecular mass transfer process. In addition to the above advantages, the permanent magnetic field can also affect other aspects of the molecular mass transfer process. For example, the permanent magnetic field can change the thermodynamic properties of molecules, thereby affecting the temperature and energy distribution of the molecules; the permanent magnetic field can also affect the chemical reaction rate of molecules, thereby affecting the chemical reaction process of molecules.

[0079] The magnetic fluid device 6 is disposed between the high-frequency co-frequency resonant fluid heater 5 and the pyrolysis chamber 22 in order to enhance the chemical reaction speed through the magnetic fluid.
