Description

Technical Field

[0001] This utility model relates to the field of biomass processing technology, and in particular to a mobile biomass carbonization processing device. Background Technology

[0002] Every year during the summer and autumn harvests in my country, along with the harvesting of crops such as wheat, rice, corn, rapeseed, cotton, and soybeans, a large amount of straw waste, including wheat straw, rice straw, corn straw, rapeseed straw, cotton straw, and soybean straw, is left piled up in the fields. Currently, the common method for disposing of this straw waste is field burning. However, this method has the following main problems: First, large-scale burning will produce a lot of black smoke, which will aggravate smog. The smoke formed by the large amount of black smoke will reduce the visibility of the surrounding air and reduce the visible range, affecting the normal operation of surrounding traffic. Secondly, the black smoke produced by burning contains a large number of pollutants such as inhalable particles, nitrogen oxides, and sulfur dioxide, which can harm human health, especially children, the elderly, and patients with respiratory diseases. Third, the burning process can easily spread to surrounding flammable materials, posing a fire hazard, especially in windy weather. Fourth, burning will cause the surface temperature to rise sharply, leading to the death of most microorganisms in the soil, damaging the soil ecology, and exacerbating soil compaction.

[0003] In addition to the straw waste mentioned above, there are also forest wastes generated from pruning fruit trees, seedlings, and green belts, as well as forest wastes from processing timber into slabs. If these biomasses are not handled properly, they will not only waste resources but also pose serious ecological risks. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical problem to be solved by this utility model is to provide a mobile biomass carbonization treatment equipment with high resource utilization and air and soil friendliness.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is to design a mobile biomass carbonization treatment device capable of carbonizing biomass. This device can be moved with the help of external mobile equipment such as mobile carts or transport trucks, enabling switching between working scenarios. The device uses carbonization to process biomass such as straw and forestry waste. Biomass typically does not require cutting; as long as it can be placed in the furnace, whole bundles of straw waste, whole pieces of forestry waste, or whole bundles of forestry waste can be directly fed into the furnace chamber. Furthermore, the gas discharged during the carbonization process does not contain black smoke; the discharged gas is air-polluting and is usually transparent. If the biomass has a high moisture content, the discharged gas may also contain water vapor, typically appearing as a white mist.

[0006] The technical solution adopted in this utility model is as follows: the mobile biomass carbonization treatment equipment includes: a furnace body in the form of a box, a top feed port communicating with the furnace cavity at the top of the furnace body, and a side carbon outlet communicating with the furnace cavity on the bottom side wall of the furnace body. A furnace door is provided at the side carbon outlet, which is used to close the side carbon outlet. When it is necessary to remove carbon powder from the furnace cavity, the furnace door is opened, and ash removal is performed through the side carbon outlet. In the actual manufacturing process, the number of side carbon outlets is determined according to the actual size of the furnace body, and can be two or more. When the number of side carbon outlets is two or more, the side carbon outlets can be evenly spaced on the side of the side wall.

[0007] A movable grate is provided in the lower section of the furnace cavity of the furnace body. The movable grate moves horizontally in the front-to-back direction. The process of moving the movable grate is to allow the ash on the movable grate (ash produced by the complete combustion of the igniter and char powder produced by the incomplete combustion of biomass) to fall downward through the gap between the grate rods on the movable grate.

[0008] At least one bottom air distribution channel is provided on the side wall of the furnace body, and each bottom air distribution channel is connected to the furnace cavity of the furnace body. Each bottom air distribution channel is located below the movable grate. At least one upper air distribution channel is provided on the side wall of the furnace body. Each upper air distribution channel is connected to the furnace cavity of the furnace body and is located above the movable grate. An air supply device is also installed outside the furnace body to supply air to the furnace cavity through each bottom air distribution channel and each upper air distribution channel.

[0009] Furthermore, in the aforementioned mobile biomass carbonization equipment, the spacing between any two adjacent grate rods in the movable grate is 20–30 mm.

[0010] Furthermore, in the aforementioned mobile biomass carbonization treatment equipment, when the number of bottom air distribution channels is greater than or equal to 2, the bottom air distribution channels are evenly spaced around the furnace body; when the number of upper air distribution channels is greater than or equal to 2, the upper air distribution channels are evenly spaced around the furnace body.

[0011] Furthermore, in the aforementioned mobile biomass carbonization treatment equipment, the air conveying device includes: a main fan; Each bottom air distribution channel is connected to the air outlet of the main fan through its corresponding first connecting pipe, and each first connecting pipe is equipped with a first regulating valve to adjust the air flow rate; Each upper air distribution duct is connected to the air outlet of the main fan through its corresponding second connecting pipe, and each second connecting pipe is equipped with a second regulating valve to adjust the air flow rate.

[0012] Furthermore, in the aforementioned mobile biomass carbonization treatment equipment, the air conveying device includes: a first fan and a second fan; Each bottom air distribution channel is connected to the air outlet of the first fan through its corresponding first connecting pipe, and each first connecting pipe is equipped with a first regulating valve to adjust the air flow rate. Each upper air distribution duct is connected to the air outlet of the second fan through its corresponding second connecting pipe, and each second connecting pipe is equipped with a second regulating valve to adjust the air flow rate.

[0013] Furthermore, in the aforementioned mobile biomass carbonization treatment equipment, at least one top air distribution channel is provided at the top of the furnace body, and each top air distribution channel is connected to the furnace cavity of the furnace body; each top air distribution channel is arranged to gradually slope downward from the air inlet to the air outlet. An air supply device is also installed outside the furnace body to supply air to the furnace cavity through each bottom air distribution channel, each upper air distribution channel, and each top air distribution channel.

[0014] Furthermore, in the aforementioned mobile biomass carbonization treatment equipment, when the number of each top air distribution channel is greater than or equal to 2, each top air distribution channel is evenly spaced around the furnace body.

[0015] Furthermore, in the aforementioned mobile biomass carbonization treatment equipment, the air conveying device includes: a main fan; Each bottom air distribution channel is connected to the air outlet of the main fan through its corresponding first connecting pipe, and each first connecting pipe is equipped with a first regulating valve to adjust the air flow rate; Each upper air distribution duct is connected to the air outlet of the main fan through its corresponding second connecting pipe, and each second connecting pipe is equipped with a second regulating valve to adjust the air flow rate; Each top air distribution duct is connected to the air outlet of the main fan through its corresponding third connecting pipe, and each third connecting pipe is equipped with a third regulating valve to adjust the air flow rate.

[0016] Furthermore, in the aforementioned mobile biomass carbonization treatment equipment, the air conveying device includes: a first fan, a second fan, and a third fan; Each bottom air distribution channel is connected to the air outlet of the first fan through its corresponding first connecting pipe, and each first connecting pipe is equipped with a first regulating valve to adjust the air flow rate. Each upper air distribution duct is connected to the air outlet of the second fan through its corresponding second connecting pipe, and each second connecting pipe is equipped with a second regulating valve to adjust the air flow rate.

[0017] Each top air distribution duct is connected to the air outlet of the third fan through its corresponding third connecting pipe, and each third connecting pipe is equipped with a third regulating valve to adjust the air flow rate.

[0018] The beneficial effects of this utility model are as follows: First, the gas emitted during the processing of biomass such as straw and forestry waste does not contain black smoke and is a non-polluting gas that poses no harm to the atmospheric environment or human health. Second, as long as the size of the biomass is smaller than the size of the furnace inlet, it can be directly put into the furnace in whole bundles or whole pieces for carbonization without any other processing such as cutting or unbundling before being put into the furnace. Third, there is no risk of fire. Fourth, the carbon powder produced by carbonization can be directly discharged into the soil to improve the soil or collected and processed into carbon-based fertilizer, which can be used for soil remediation and crop quality improvement, resulting in high resource utilization.

[0023] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and preferred embodiments.

[0024] Exemplary embodiments will be described more fully below with reference to the accompanying drawings; however, these exemplary embodiments may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will enable those skilled in the art to fully understand the scope of this disclosure. Example 1

[0025] like Figure 1 As shown, the mobile biomass carbonization equipment described in this embodiment includes: a furnace body 1 in the form of a box, the top of the furnace body 1 having a top feed port 2 communicating with the furnace cavity of the furnace body 1, and a side carbon outlet 3 on the bottom side wall of the furnace body 1 communicating with the furnace cavity of the furnace body 1. A furnace door 4 is provided at the side carbon outlet 3. During the operation of the equipment, the side carbon outlet 3 is closed by the furnace door 4 to prevent combustible gas in the furnace cavity of the furnace body 1 from escaping outward from the side carbon outlet 3.

[0026] The overall structure of furnace body 1 can refer to the structure of a carbonization furnace body. It can be formed by stacking refractory bricks inside, with an insulation layer wrapped around the outside of the refractory brick layer, and then wrapped with a metal shell outside the insulation layer. The inside can be a bare refractory brick layer, or a metal inner shell can be attached inside the refractory brick layer.

[0027] A movable grate 5 is provided in the lower section of the furnace cavity of the furnace body 1. The grate belt formed by the grate rods on the movable grate 5 moves horizontally from back to front or from front to back. Preferably, the movable grate is a chain grate. The chain grate is a mature existing structure, so its structure will not be described in detail here.

[0028] The furnace body 1 is typically manufactured with a width of approximately 1 to 3 meters and a length of approximately 4 to 6 meters, or even wider and longer. The grate belt in the movable grate 5 moves along the length of the furnace body 1.

[0029] In addition, the distance between any two adjacent grate rods in the movable grate 5 needs to be set to 20-30mm. This distance is necessary to ensure that the air supplied from each bottom air distribution channel 6 can reach the movable grate 5 smoothly, providing sufficient air for the combustibles placed on the movable grate 5 for ignition. It also needs to ensure that the char powder produced after the equipment is in normal operation can fall down smoothly through the gap between the two adjacent grate rods, and that unburned or carbonized biomass will not fall down through the gap between the two adjacent grate rods, thereby improving the biomass processing efficiency.

[0030] At this time, the area below the movable grate 5 in the furnace cavity of the furnace body 1 is the carbon powder collection area 7. The carbon powder collected in the carbon powder collection area 7 can be directly discharged into the soil to improve the soil, or it can be collected and processed into carbon-based fertilizer. The carbon-based fertilizer can be used for soil remediation and crop quality improvement.

[0031] The area on the movable grate 5 used to place combustibles for ignition is the primary combustion zone 8.

[0032] At least one bottom air distribution channel 6 is provided on the side wall of the furnace body 1. Each bottom air distribution channel 6 communicates with the furnace cavity of the furnace body 1, and each bottom air distribution channel 6 is located below the movable grate 5. Figure 1 The diagram shows a bottom air distribution channel 6 installed on the side wall of the furnace body 1. Of course, multiple bottom air distribution channels 6 can be installed as needed. When multiple bottom air distribution channels 6 are installed, i.e., when the number of bottom air distribution channels 6 is greater than or equal to 2, the preferred arrangement of the bottom air distribution channels 6 is that they are evenly spaced around the circumference of the furnace body 1. This allows for a more uniform distribution of air entering the primary combustion zone 8, ensuring that the combustible material for ignition can burn completely in the primary combustion zone 8. Figure 2 The diagram shows a structure with two bottom air distribution channels 6 on the side wall of the furnace body 1. The two bottom air distribution channels 6 are symmetrically distributed with respect to the center line of the furnace body 1.

[0033] like Figure 1 As shown, in this embodiment, at least one upper air distribution channel 9 is provided on the side wall of the furnace body 1. Each upper air distribution channel 9 is connected to the furnace cavity of the furnace body 1. Each upper air distribution channel 9 is located above the movable grate 5. The area where air is supplied by each upper air distribution channel 9 is above the primary combustion zone 8, which is the secondary combustion zone 10. After the combustible material for ignition is ignited and burned, biomass is continuously fed into the furnace cavity of the furnace body 1. The feeding method can be a hoisting feeding method. The movable grate 5 also begins to move. At this time, the biomass fed into the furnace cavity of the furnace body 1 is in the secondary combustion zone 10. The biomass is incompletely burned in this zone, that is, it is in the carbonization process. Carbonization produces combustible gas and carbon powder. The combustible gas is used as combustible material for combustion in the secondary combustion zone 10.

[0034] like Figure 1 The diagram shows a structural schematic of an upper air distribution channel 9 installed on the side wall of the furnace body 1. Of course, multiple upper air distribution channels 9 can be installed according to actual conditions. When multiple upper air distribution channels 9 are installed, i.e., when the number of upper air distribution channels 9 is greater than or equal to 2, the preferred arrangement of the upper air distribution channels 9 is that they are evenly spaced around the circumference of the furnace body 1. This allows for a more uniform distribution of air entering the secondary combustion zone 10, ensuring that the degree of incomplete combustion of biomass at the same height in the secondary combustion zone 10 is basically synchronized, thus improving the uniformity of carbonization. Figure 2 The diagram shows a structure with two upper air distribution channels 9 on the side wall of the furnace body 1. The two upper air distribution channels 9 are symmetrically distributed with respect to the center line of the furnace body 1.

[0035] An air supply device is also provided outside the furnace body 1 to supply air to the furnace cavity of the furnace body 1 through each bottom air distribution channel 6 and each upper air distribution channel 9.

[0036] This embodiment provides two forms of air delivery device. The first form includes a main fan 11; each bottom air distribution channel 6 is connected to the air outlet of the main fan 11 via its corresponding first connecting pipe 12, and each first connecting pipe 12 is equipped with a first regulating valve 13 to adjust the airflow rate. In use, the first regulating valve 13 is adjusted according to the required air volume of the primary combustion zone 8 to regulate the airflow rate delivered to the primary combustion zone 8.

[0037] Each upper air distribution duct 9 is connected to the air outlet of the main fan 11 via its corresponding second connecting pipe 14. Each second connecting pipe 14 is equipped with a second regulating valve 15 to adjust the airflow rate. During use, the second regulating valve 15 is adjusted according to the required air volume of the secondary combustion zone 10 to regulate the airflow rate supplied to the secondary combustion zone 10.

[0038] The second form of the air delivery device is: the air delivery device includes: a first fan and a second fan; each bottom air distribution channel 6 is connected to the air outlet of the first fan through its corresponding first connecting pipe 12, and each first connecting pipe 12 is provided with a first regulating valve 13 to regulate the air flow rate.

[0039] Each upper air distribution duct 9 is connected to the air outlet of the second fan through its corresponding second connecting pipe 14, and each second connecting pipe 14 is equipped with a second regulating valve 15 to regulate the air flow rate.

[0040] The mobile biomass carbonization equipment described in this embodiment has the following main advantages: First, the gas emitted during the processing of biomass such as straw and forestry waste does not contain black smoke and is a non-polluting gas that poses no harm to the atmospheric environment or human health. Second, as long as the size of the biomass is smaller than the furnace inlet size, it can be directly put into the furnace in whole bundles or whole pieces for carbonization without any other processing such as cutting or unbundling before being put into the furnace. Third, it does not pose a fire hazard. Fourth, the carbon powder produced by carbonization can be directly discharged into the soil to improve the soil or collected and processed into carbon-based fertilizer, which can be used for soil remediation and crop quality improvement, resulting in high resource utilization. Example 2

[0041] This embodiment, based on Embodiment 1, further includes at least one top air distribution channel 16 at the top of the furnace body 1, such as... Figure 3 As shown, each top air distribution channel 16 is connected to the furnace cavity of the furnace body 1; each top air distribution channel 16 is arranged to gradually slope downward from the air inlet to the air outlet.

[0042] The area where air is supplied through the top air distribution channels 16 is above the secondary combustion zone 10, which is the tertiary combustion zone 17. The material undergoes incomplete combustion, i.e., carbonization, in this secondary combustion zone 10. The combustible gases produced during carbonization are burned off in this zone. However, in actual use, it has been found that sometimes a small portion of the combustible gas flows upwards after passing through the secondary combustion zone 10. In this case, the air supplied to the tertiary combustion zone 17 ensures that this small portion of remaining combustible gas is completely burned off. This ensures that the gas discharged from the top feed inlet 2 does not contain black smoke and is a non-polluting gas, usually transparent. At most, when the biomass has a high moisture content, the discharged gas may contain water vapor, making it appear as a white gas.

[0043] When the number of top air distribution channels 16 is greater than or equal to 2, the top air distribution channels 16 are evenly spaced around the furnace body 1. This allows for a more uniform distribution of air entering the tertiary combustion zone 17, ensuring that combustible gases escaping upwards from the secondary combustion zone 10 are completely burned in the tertiary combustion zone 17. Figure 3 The diagram shows a structure with two top air distribution channels 16 on the side wall of the furnace body 1. The two top air distribution channels 16 are symmetrically distributed with respect to the center line of the furnace body 1.

[0044] An air supply device is also provided outside the furnace body 1 to supply air to the furnace cavity of the furnace body 1 through each bottom air distribution channel 6, each upper air distribution channel 9, and each top air distribution channel 16.

[0045] This embodiment provides two forms of air delivery device. The first form includes a main fan 11; each bottom air distribution channel 6 is connected to the air outlet of the main fan 11 via its corresponding first connecting pipe 12, and each first connecting pipe 12 is equipped with a first regulating valve 13 to adjust the airflow rate. In use, the first regulating valve 13 is adjusted according to the required air volume of the primary combustion zone 8 to regulate the airflow rate delivered to the primary combustion zone 8.

[0046] Each upper air distribution duct 9 is connected to the air outlet of the main fan 11 via its corresponding second connecting pipe 14. Each second connecting pipe 14 is equipped with a second regulating valve 15 to adjust the airflow rate. During use, the second regulating valve 15 is adjusted according to the required air volume of the secondary combustion zone 10 to regulate the airflow rate supplied to the secondary combustion zone 10.

[0047] Each top air distribution duct 16 is connected to the air outlet of the main fan 11 via its corresponding third connecting pipe 18. Each third connecting pipe 18 is equipped with a third regulating valve 19 to adjust the airflow rate. During use, the third regulating valve 19 is adjusted according to the required air volume of the tertiary combustion zone 17 to regulate the flow rate of intermediate air supplied to the tertiary combustion zone 17.

[0048] The second form of the air delivery device is: the air delivery device includes: a first fan, a second fan and a third fan; each bottom air distribution channel 6 is connected to the air outlet of the first fan through its corresponding first connecting pipe 12, and each first connecting pipe 12 is provided with a first regulating valve 13 to regulate the air flow rate.

[0049] Each upper air distribution duct 9 is connected to the air outlet of the second fan through its corresponding second connecting pipe 14, and each second connecting pipe 14 is equipped with a second regulating valve 15 to regulate the air flow rate.

[0050] Each top air distribution duct 16 is connected to the air outlet of the third fan through its corresponding third connecting pipe 18, and each third connecting pipe 18 is equipped with a third regulating valve 19 for adjusting the air flow rate.

[0051] The mobile biomass carbonization equipment described in this embodiment has the following main advantages: First, the gas emitted during the processing of biomass such as straw and forestry waste does not contain black smoke and is a non-polluting gas that poses no harm to the atmospheric environment or human health; the processing effect is better than that of Embodiment 1; Second, as long as the size of the biomass is smaller than the furnace body's inlet size, it can be directly put into the furnace in whole bundles or whole pieces for carbonization without any other processing such as cutting or unbundling before being put into the furnace; Third, there is no risk of fire; Fourth, the carbon powder produced by carbonization can be directly discharged into the soil to improve the soil, or collected and processed into carbon-based fertilizer, which can be used for soil remediation and crop quality improvement, resulting in high resource utilization.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any modifications or equivalent changes made based on the technical essence of the present utility model shall still fall within the scope of protection claimed by the present utility model.
