Description

Technical Field

[0001] This application relates to the field of carbon-containing organic matter treatment technology, and more specifically, to an apparatus and process for the gasification and ashing of carbon-containing organic matter. Background Technology

[0002] The gasification and pyrolysis of carbonaceous compounds is an endothermic process, generally requiring a high temperature environment of 650–1400℃, which consumes a large amount of energy. Simultaneously, within this temperature range, almost all halogenated compounds and sulfides liquefy and gasify into the flue gas, making flue gas treatment processes cumbersome, and frequently causing pipe blockages or corrosion, sometimes leading to production shutdowns for maintenance. This problem is frequently encountered in industries such as coal gasification and waste organic matter pyrolysis.

[0003] The inventor's previous international invention patent PCT / CN2011 / 070064, "A Two-Stage Plasma Gasification Melting and Cracking Method and Apparatus Containing Organic Waste," only described a "single vertical shaft" furnace structure for low-temperature magnetic oxygen-induced plasma gasification and ashing integrated into the entire system. However, this structure is not suitable for processing small pieces of material or even powder.

[0004] To avoid the liquefaction and vaporization temperature range of halogen compounds and sulfides, ensuring that most halogen compounds and sulfides remain in the ashing, and requiring almost no external energy input, thus solving the problem of gasification and ashing of carbon-containing compounds, the inventors of this application have also filed ZL 202122808231.3 "Plasma Gasification and Melting System for Combustible Solid Waste" and invention patent application number 2021111353737.8 "Plasma Gasification and Melting System and Process for Combustible Solid Waste," which mainly describe the process method and system of three-stage plasma gasification and melting of solid waste, but do not provide a detailed introduction to the structure and specific process of the first-stage low-temperature magnetic oxygen-induced plasma gasification and ashing equipment.

[0005] Therefore, in order to address the technological gaps in the existing technology, this application is made for a carbon compound low-temperature magnetic oxygen plasma multi-hearth furnace gasification and ashing device and its process. Summary of the Invention

[0006] The purpose of this application is to provide an apparatus for the gasification and ashing of carbon-containing organic matter, which can form a low-temperature magnetic oxygen plasma region in the furnace to gasify and ashing carbon-containing organic matter.

[0007] Another objective of this application is to provide a process for the gasification and ashing of carbon-containing organic matter, which, relying on the aforementioned apparatus, can render carbon-containing organic matter harmless.

[0008] The technical problem solved by this application is achieved by the following technical solution.

[0009] On one hand, embodiments of this application provide an apparatus for gasification and ashing of carbon-containing organic matter, including a cylindrical furnace body, a cylindrical shaft vertically disposed within the furnace body, and a multi-layer furnace bed perpendicular to the cylindrical shaft. Each furnace bed has a hollow rotating rake and a magnetic generator disposed on its inner circumference. The rotating rake is connected to the cylindrical shaft, and an electrolytic material bed is disposed in the gap between the rotating rake and the magnetic generator in the furnace bed.

[0010] On the other hand, embodiments of this application provide a process for the gasification and ashing of carbon-containing organic matter, including the following steps:

[0011] Combustion-supporting gas is introduced into the multi-hearth furnace and ignited. The combustion-supporting gas is ionized inside the furnace, releasing electrons.

[0012] Carbonaceous organic matter is fed into the multi-hearth furnace through the feed inlet located at the top of the furnace body. Due to the action of the cylindrical shaft and the rotating rake, the carbonaceous organic matter moves in an Archimedean spiral motion from top to bottom inside the device.

[0013] Ionized electrons vaporize and ashing carbon-containing organic matter;

[0014] The gas after gasification and ashing is drawn out from the gas outlet by a downward suction method, and the magnetized ash after gasification and ashing is discharged from the ash outlet at the bottom of the furnace.

[0015] Compared with the prior art, the embodiments of this application have at least the following advantages or beneficial effects:

[0016] This application involves installing a circumferentially radial magnetic generator on the hearth of a traditional multi-hearth furnace, and filling the gaps between the magnetic generators with pyroelectric material. In a multi-level, multi-pole magnetic field at ≤500℃, oxygen molecules in the combustion gas ionize to form plasma, dramatically increasing reactivity. Simultaneously, the pyroelectric material releases a large number of electrons. In a magnetic field of 0.1–0.5 Tesla, the electrons flow like a waterfall at a speed of 1.43–3.19 × 10⁻⁶. 3 The continuous, forward-facing, clustered bombardment of carbonaceous organic matter at a speed of m / s severely weakens the cohesion of the organic matter, gradually decomposing it and completing the gasification and ashing process. This device and process can be applied to materials of different sizes for the harmless treatment of carbonaceous organic matter. Attached Figure Description

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below. Where specific conditions are not specified in the embodiments, conventional conditions or conditions recommended by the manufacturer shall apply. Reagents or instruments whose manufacturers are not specified are all conventional products that can be purchased commercially.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present application will now be described in detail with reference to specific embodiments.

[0026] An apparatus for gasification and ashing of carbonaceous organic matter includes a cylindrical furnace body 1, a cylindrical shaft 2 vertically disposed within the furnace body 1, and a multi-layer furnace bed 3 perpendicular to the cylindrical shaft 2. The apparatus is characterized in that each furnace bed 3 has a hollow rotating rake 4 and a magnetic generator 5 arranged around its inner circumference. The rotating rake 4 is connected to the cylindrical shaft 2, and an electrolytic material bed 6 is disposed between adjacent magnetic generators 5 within the furnace bed 3.

[0027] In some embodiments of this application, the furnace body 1 is a multi-layer water-cooled furnace body, with a feed inlet 7 at the top and an ash outlet 8 and an air outlet at the bottom.

[0028] In some embodiments of this application, the cylindrical shaft 2 coincides with the central axis of the furnace body 1, and a driving device 9 is provided at the bottom of the furnace body 1, which is connected to the cylindrical shaft 2.

[0029] In some embodiments of this application, the furnace body 1 corresponding to the furnace bed 3 is provided with an igniter interface 10 and an observation hole 11.

[0030] In some embodiments of this application, magnetic nozzles 12 are provided on the top and sides of the furnace body 1, and the magnetic nozzle 12 located on the top is connected to the upper end of the cylindrical shaft 2.

[0031] In some embodiments of this application, the lower end face of the rotary rake 4 is provided with hollow rake teeth 13, and the rotary rake 4 and the rake teeth 13 are internally connected.

[0032] In some embodiments of this application, the above-mentioned energizing material bed 6 is filled with energizing material, including tourmaline.

[0033] In some embodiments of this application, an air lock is installed at the upper end of the feed inlet 7, and a solenoid valve is provided at the air inlet front end of the magnetic nozzle 12.

[0034] A process for gasification and ashing of carbon-containing organic matter using the above-mentioned apparatus includes the following steps:

[0035] Combustion-supporting gas is introduced into the multi-hearth furnace and ignited. The combustion-supporting gas is ionized inside the furnace, releasing electrons.

[0036] Carbon-containing organic matter is fed into the multi-hearth furnace through the feed inlet 7 located at the top of the furnace body 1. Due to the action of the cylindrical shaft 2 and the rotating rake 4, the carbon-containing organic matter moves in an Archimedean spiral motion from top to bottom in the device.

[0037] Ionized electrons vaporize and ashing carbon-containing organic matter;

[0038] The gas after gasification and ashing is drawn out from the gas outlet by a downward suction method, and the magnetized ash after gasification and ashing is discharged from the ash outlet 8 at the bottom of the furnace.

[0039] Carbon-containing compounds, after being vaporized and ashed by magnetic oxygen plasma at a low temperature (<500℃), produce a vaporized gas at ~450℃ containing combustible small molecules such as CO, CH4, and C. n H m Besides gases such as H2, the gasified gas also contains vaporized tar components, wood vinegar, and water vapor. The tar composition is very complex, mainly composed of benzene, toluene, naphthalene, phenols, and their derivatives. Because tar condenses at low temperatures, it can cause blockages, pipe corrosion, and aerosol formation in later stages of production. Furthermore, if it enters the engine, it may polymerize and clog the intake passages, coolers, and filters. Due to the complex composition of the waste, the gasified gas also contains some harmful organic compounds in uncertain amounts.

[0040] In some embodiments of this application, the gasification and ashing temperature in the multi-hearth furnace device is 450-500°C, the magnetic field strength is 0.1-0.5T, and the pressure is -20--50Pa.

[0041] The features and performance of this application will be further described in detail below with reference to the embodiments.

[0042] Example 1

[0043] This embodiment provides a multi-hearth furnace device for the gasification and ashing of carbon-containing organic matter, referencing... Figures 1-5 Including the cylindrical furnace body 1, when designing the furnace chamber dimensions, a total hearth gasification intensity of 1.5–3 M is selected. 3 / M 2 ·D(24h). The furnace body 1 is a vertically placed steel multi-cooling multi-layer cylinder, which is basically the same as the traditional multi-hearth furnace. Inside the furnace body 1, there is a vertically arranged cylindrical shaft 2. The cylindrical shaft 2 is a hollow cylindrical structure that runs through the entire furnace body 1 and extends out of the furnace body 1 at the top.

[0044] The furnace body 1 is also equipped with multiple layers of furnace beds 3. Each layer of furnace bed 3 is perpendicular to the cylindrical shaft 2. The height of each layer is 300-600mm. Multiple hollow rotating rakes 4 are arranged circumferentially and radially in each furnace bed 3, preferably 2-4 and evenly distributed. The rotating rakes 4 are connected to the cylindrical shaft 2. When in use, the combustion-supporting gas can enter the rotating rakes 4 from the cylindrical shaft 2. Since the rotating rakes 4 are connected to the cylindrical shaft 2, the cylindrical shaft 2 can drive the rotating rakes 4 to rotate, thereby stirring the raw materials in the multi-hearth furnace.

[0045] Each hearth 3 has multiple magnetic generators 5 arranged circumferentially and radially, specifically a primary magnetic generator 51. The multiple primary magnetic generators 51 are evenly distributed, and the spacing between the primary magnetic generators 51 of adjacent layers is 20-40cm. When this value is exceeded, a secondary magnetic generator 52 and a tertiary magnetic generator 53 can be added sequentially between adjacent primary magnetic generators 51.

[0046] An electric material bed 6 is provided in the gap between adjacent magnetic generators 5 inside the furnace bed 3. The electric material bed 6 is filled with electric material, and in this embodiment, the electric material is preferably tourmaline.

[0047] Furthermore, the furnace body 1 corresponding to the furnace bed 3 is provided with an igniter interface 10 and an observation hole 11. Ignition can be started by relying on the burner set outside the furnace body 1. Once the furnace temperature reaches the required temperature, the burner can be turned off.

The gas generated is led out through the gas outlet, and the magnetized ash generated is discharged through the ash outlet 8.

[0050] Furthermore, in order to reduce the entry of nitrogen, an airlock is also provided at the upper end of the feed inlet 7 in this embodiment.

Based on Embodiment 1, this embodiment further defines that the cylindrical shaft 2 coincides with the central axis of the furnace body 1, and a driving device 9 is provided at the bottom of the furnace body 1. The driving device 9 is connected to the cylindrical shaft 2.

[0053] In this embodiment, the central axis of the cylindrical shaft 2 coincides with the central axis of the cylindrical furnace body 1, that is, the cylindrical shaft 2 is vertically arranged at the center inside the furnace body 1, which has better stability. A drive device 9, specifically a drive motor, is provided at the bottom of the furnace body 1. The drive device 9 is electrically connected to the cylindrical shaft 2, that is, the drive motor drives the cylindrical shaft 2 to rotate in the furnace body 1.

[0054] Example 4

[0055] This embodiment provides a multi-hearth furnace device for gasification and ashing of carbon-containing organic matter, which is basically the same as that in Embodiment 1. The similarities will not be repeated. Based on Embodiment 1, this embodiment further defines that the top and sides of the furnace body 1 are provided with magnetic air nozzles 12, and the magnetic air nozzle 12 located at the top is connected to the upper end of the cylindrical shaft 2.

[0056] In this embodiment, all magnetic nozzles 12 can be uniformly connected to industrial oxygen pipelines. Part of the combustion-supporting gas in the multi-hearth furnace comes from the magnetic nozzles 12 located at the top of the furnace body 1. The magnetized combustion-supporting gas passes through the hollow cylindrical shaft 2 and the rotating rake 4 before entering the furnace chamber. The other part of the combustion-supporting gas comes directly from the magnetic nozzles 12 installed on the side wall shell of the furnace body 1.

[0057] In addition, in order to control the temperature inside the furnace, an electromagnetic valve can be installed at the front end of the magnetic nozzle 12 to control the air intake.

[0058] Example 5

[0059] This embodiment provides a multi-hearth furnace device for gasification and ashing of carbon-containing organic matter, which is basically the same as that in Embodiment 1. The similarities will not be repeated. Based on Embodiment 1, this embodiment further specifies that the lower end face of the rotating rake 4 is provided with hollow rake teeth 13, and the rotating rake 4 and the rake teeth 13 are internally connected.

[0060] In this embodiment, the rotating rake 4 is positioned above the magnetic generator 5 and the bed of ionizing material 6. The rotating rake 4 is a hollow cuboid shape, and its lower end face is provided with a plurality of hollow rake teeth 13. The rake teeth 13 are inverted cones with open lower ends, and the rotating rake 4 and the rake teeth 13 are internally connected to facilitate the flow of combustion-supporting gas.

[0061] Example 6

[0062] This embodiment provides a process for the gasification and ashing of carbon-containing organic matter, including the following steps:

[0063] Combustion-supporting gas is introduced into the multi-hearth furnace through the magnetic nozzle 12. The combustion-supporting gas introduced through the magnetic nozzle 12 at the top passes through the hollow cylindrical shaft 2, the rotating rake 4 and the rake teeth 13 in sequence before entering the furnace. The entire furnace is under a slight negative pressure of -30Pa and the temperature is set at 480℃. In the multi-level multi-pole magnetic field of ≤500℃, the oxygen molecules in the combustion-supporting gas are ionized to form plasma, and the reactivity is greatly increased. At the same time, the pyroelectric material releases a large number of electrons.

[0064] Carbonaceous organic matter is fed into the multi-hearth furnace through the feed inlet 7 located at the top of the furnace body 1. The cylindrical shaft 2 drives the rotating rake 4 and rake teeth 13 to rotate slowly by the drive device 9 set at the bottom of the furnace at a speed of 0.5 r / min. Due to the action of the cylindrical shaft 2 and the rotating rake 4, the carbonaceous organic matter falls from the upper furnace bed 3 to the lower furnace bed 3 under the push of the rotating rake 4, and moves in an Archimedean spiral motion from the outside to the inside or from the inside to the outside on each furnace bed 3.

[0065] In a 0.1T magnetic field, electrons move like a waterfall at speeds of 1.43–3.19 × 10⁻⁶. 3 The continuous forward cluster bombardment of carbon-containing organic matter at m / s weakens the cohesion of the organic matter, causing it to decompose gradually and complete the gasification and ashing process.

[0066] The gas after gasification and ashing is drawn out from the gas outlet by a downward suction method, and the magnetized ash after gasification and ashing is discharged from the ash outlet 8 at the bottom of the furnace.

[0067] Example 7

[0068] This embodiment provides a process for the gasification and ashing of carbon-containing organic matter, including the following steps:

[0069] Combustion-supporting gas is introduced into the multi-hearth furnace through the magnetic nozzle 12. The combustion-supporting gas introduced through the magnetic nozzle 12 at the top passes through the hollow cylindrical shaft 2, the rotating rake 4 and the rake teeth 13 in sequence before entering the furnace. The entire furnace is under a slight negative pressure of -50Pa and the temperature is set at 460℃. In the multi-level multi-pole magnetic field of ≤500℃, the oxygen molecules in the combustion-supporting gas are ionized to form plasma, and the reactivity is greatly increased. At the same time, the pyroelectric material releases a large number of electrons.

[0070] Carbonaceous organic matter is fed into the multi-hearth furnace through the feed inlet 7 located at the top of the furnace body 1. The cylindrical shaft 2 drives the rotating rake 4 and rake teeth 13 to rotate slowly by the drive device 9 set at the bottom of the furnace at a speed of 0.8 r / min. Due to the action of the cylindrical shaft 2 and the rotating rake 4, the carbonaceous organic matter falls from the upper furnace bed 3 to the lower furnace bed 3 under the push of the rotating rake 4, and moves in an Archimedean spiral motion from the outside to the inside or from the inside to the outside on each furnace bed 3.

[0071] In a 0.1T magnetic field, electrons move like a waterfall at speeds of 1.43–3.19 × 10⁻⁶. 3 The continuous forward cluster bombardment of carbon-containing organic matter at m / s weakens the cohesion of the organic matter, causing it to decompose gradually and complete the gasification and ashing process.

[0072] The gas after gasification and ashing is drawn out from the gas outlet by a downward suction method, and the magnetized ash after gasification and ashing is discharged from the ash outlet 8 at the bottom of the furnace.

[0073] Example 8

[0074] This embodiment provides a process for the gasification and ashing of carbon-containing organic matter, including the following steps:

[0075] Combustion-supporting gas is introduced into the multi-hearth furnace through the magnetic nozzle 12. The combustion-supporting gas introduced through the magnetic nozzle 12 at the top passes through the hollow cylindrical shaft 2, the rotating rake 4 and the rake teeth 13 in sequence before entering the furnace. The entire furnace is under a slight negative pressure of -20Pa and the temperature is set at 490℃. In the multi-level multi-pole magnetic field of ≤500℃, the oxygen molecules in the combustion-supporting gas are ionized to form plasma, and the reactivity is greatly increased. At the same time, the pyroelectric material releases a large number of electrons.

[0076] Carbonaceous organic matter is fed into the multi-hearth furnace through the feed inlet 7 located at the top of the furnace body 1. The cylindrical shaft 2 drives the rotating rake 4 and rake teeth 13 to rotate slowly by the drive device 9 set at the bottom of the furnace. The rotation speed is 0.2 r / min. Due to the action of the cylindrical shaft 2 and the rotating rake 4, the carbonaceous organic matter falls from the upper furnace bed 3 to the lower furnace bed 3 under the push of the rotating rake 4. On each furnace bed 3, it moves in an Archimedean spiral motion from the outside to the inside or from the inside to the outside.

[0077] In a 0.1T magnetic field, electrons move like a waterfall at speeds of 1.43–3.19 × 10⁻⁶.3 The continuous forward cluster bombardment of carbon-containing organic matter at m / s weakens the cohesion of the organic matter, causing it to decompose gradually and complete the gasification and ashing process.

[0078] The gas after gasification and ashing is drawn out from the gas outlet by a downward suction method, and the magnetized ash after gasification and ashing is discharged from the ash outlet 8 at the bottom of the furnace.

[0079] In summary, the apparatus and process for gasification and ashing of carbon-containing organic matter according to embodiments of this application have the following advantages:

[0080] This application involves installing a circumferentially radial magnetic generator 5 on the hearth 3 of a conventional multi-hearth furnace, and filling the gaps between the magnetic generator 5 with pyroelectric material. In a multi-level, multi-pole magnetic field at ≤500℃, oxygen molecules in the combustion gas ionize to form plasma, resulting in a dramatic increase in reactivity. Simultaneously, the pyroelectric material releases a large number of electrons. In a magnetic field of 0.1–0.5 Tesla, the electrons flow like a waterfall at a speed of 1.43–3.19 × 10⁻⁶. 3 The continuous, forward-facing, clustered bombardment of carbonaceous organic matter at a speed of m / s severely weakens the cohesion of the organic matter, gradually decomposing it and completing the gasification and ashing process. This device and process can be applied to materials of different sizes for the harmless treatment of carbonaceous organic matter.
