[0027] For a clearer understanding of the technical features, objectives, and effects of the present utility model, the specific embodiments of the present utility model will now be described with reference to the accompanying drawings.
[0028] As Figure 1 shown, this embodiment provides a two-stage continuous carbonization device, including a vertical carbonization chamber 1, a vertical combustion chamber 2, a horizontal carbonization chamber 3, a horizontal combustion chamber 4, and a storage tank 5;
[0029] A part of the vertical carbonization chamber 1 is located inside the vertical combustion chamber 2, and the upper and lower ends of the vertical carbonization chamber 1 respectively extend out of the upper and lower ends of the vertical combustion chamber 2; the vertical carbonization chamber 1 is a moving bed carbonization furnace, and a vertical feeding screw 11 is provided inside the vertical carbonization chamber 1; a part of the horizontal carbonization chamber 3 is located inside the horizontal combustion chamber 4, and the first end and the second end of the horizontal carbonization chamber 3 along its axis respectively extend out of both ends of the horizontal combustion chamber 4; the first end of the horizontal carbonization chamber 3 is located directly below the bottom end of the vertical carbonization chamber 1 and is connected to the bottom end of the vertical carbonization chamber 1 in a connectable and disconnectable manner; a horizontal feeding screw 31 is provided inside the horizontal carbonization chamber 3; the storage tank 5 is located directly below the second end of the horizontal carbonization chamber 3 and is connected to the horizontal carbonization chamber 3 in a connectable and disconnectable manner.
[0030] Among them, the axes of the vertical carbonization chamber 1 and the vertical combustion chamber 2 are both vertically arranged, and the axes of the horizontal carbonization chamber 3 and the horizontal combustion chamber 4 are both horizontally arranged; the vertical carbonization chamber 1 is located above the horizontal carbonization chamber 3. Generally, both the carbonization chamber and the combustion chamber are cylindrical, and the lower part of the vertical carbonization chamber 1 is a conical structure with a gradually decreasing inner diameter downward to facilitate the falling of materials more; the combustion chamber is coaxially arranged with the corresponding carbonization chamber, and the combustion chamber surrounds the carbonization chamber.
[0031] "Continuous" in the two-stage continuous carbonization device means continuous operation, and this device can be produced in a continuous operation mode. This carbonization device can be used for carbonizing straw. When in use, straw is added into the vertical carbonization chamber 1, the vertical combustion chamber 2 is ignited, the bottom end of the vertical carbonization chamber 1 is communicated with the first end of the horizontal carbonization chamber 3, the horizontal combustion chamber 4 is ignited, and the second end of the horizontal carbonization chamber 3 is communicated with the storage tank 5; the straw is carbonized in the vertical carbonization chamber 1 while being rotated and fed by the vertical feeding screw 11, enters the horizontal carbonization chamber 3 through the bottom end of the vertical carbonization chamber 1, is carbonized in the horizontal carbonization chamber 3 while being rotated and fed by the horizontal feeding screw 31, and finally falls into the storage tank 5. Both the vertical feeding screw 11 and the horizontal feeding screw 31 rotate and feed around their respective axes. By coordinating the rotational speeds between the two feeding screws, the stacking height inside the vertical carbonization chamber 1 can be controlled. Considering the characteristics of low bulk density and dispersion of materials such as straw, the carbonization device in this embodiment adopts a two-stage structure, and the vertical carbonization chamber 1 adopts a moving bed carbonization furnace, with a larger processing capacity. The specific structure of the moving bed carbonization furnace is prior art and will not be elaborated here.
[0032] Therefore, the carbonization equipment in this embodiment adopts a two-stage structure composed of two carbonization chambers. The vertical carbonization chamber 1 uses a moving bed carbonization furnace, which not only increases the processing capacity of materials such as straw, but also has a relatively small volume for each carbonization chamber, enabling more uniform heating of the carbonization chamber and more precise control of the reaction time. Each carbonization chamber is equipped with a feeding screw, which can not only effectively prevent dead zones in the carbonization chamber, ensure the smooth falling of materials, and is also more conducive to the precise control of the reaction time. Moreover, the two feeding screws can assist in feeding and controlling the discharging speed. Through the rotational speed coordination between the two feeding screws, the precise control of the material accumulation height in the vertical carbonization chamber 1 can be achieved, and the materials can be quickly processed and carbonized and then sent out of the storage tank 5. The discharging speed of the entire carbonization equipment can be controlled more precisely, and it can be used for continuous production, realizing the rapid continuous processing of materials such as straw, with more uniform products and lower reaction energy consumption.
[0033] The entire equipment can realize the on-site treatment of straw, with a large processing capacity, lower energy consumption, simple structure, small footprint, light weight, facilitating the on-site carbonization treatment of straw in farmland and realizing the full-quantification treatment and utilization of the products during the straw carbonization process.
[0034] Furthermore, the two-stage continuous carbonization equipment further includes a gas storage tank 61, a coke removal tank 62, and a condensation tank 63. A first igniter 21 is provided in the vertical combustion chamber 2, and a second igniter 41 is provided in the horizontal combustion chamber 4. The gas storage tank 61 is connected to the first igniter 21 and the second igniter 41 through a first gas path 611. The coke removal tank 62 is connected to the horizontal carbonization chamber 3 through a second gas path 621. The condensation tank 63 is connected to the gas storage tank 61 and the coke removal tank 62 through a third gas path 631 and a fourth gas path 632 respectively, and a pumping device (such as a gas pump 612) is provided on at least one of the first gas path 611, the second gas path 621, the third gas path 631, and the fourth gas path 632.
[0035] When carbonizing straw, the straw is added to the vertical carbonization chamber 1, and the first igniter 21 and the second igniter 41 ignite and burn the combustible gas to supply energy for carbonization. After the straw is carbonized at high temperature, the generated combustible gas enters the coke removal tank 62 through the second gas path 621 under the action of the pumping device, removes tar, then enters the condensation tank 63 through the fourth gas path 632 to remove water vapor, and the remaining combustible gas enters the gas storage tank 61 through the third gas path 631 for storage, and then is sent to the vertical combustion chamber 2 and the horizontal combustion chamber 4 through the first gas path 611 for combustion. When the combustible gas generated by straw carbonization realizes circulation, the self-circulation heating of the carbonization process can be achieved.
[0036] Through the cooperation of the defocusing tank 62, the condensation tank 63, the gas storage tank 61 and the pumping device, the combustible gas generated by the pyrolysis and carbonization of straw can be collected and introduced into the vertical combustion chamber 2 and the horizontal combustion chamber 4 for combustion. By recycling the pyrolysis gas for combustion, the continuous self-sustaining operation of the carbonization equipment can be achieved, effectively reducing the energy consumption of straw pyrolysis, realizing the self-heating carbonization technology, eliminating the need for external energy supply, reducing gas consumption, and having lower costs.
[0037] Generally, the gas storage tank 61 stores a preset amount of combustible gas.
[0038] The carbonization equipment has a self-circulating heating operation state and an external supplementary operation state. When the carbonization equipment is in the self-circulating heating operation state, the combustible gas generated in the vertical carbonization chamber 1 and the horizontal carbonization chamber 3 can enter the vertical combustion chamber 2 and the horizontal combustion chamber 4 under the action of the pumping device through the defocusing tank 62, the condensation tank 63 and the gas storage tank 61; when the carbonization equipment is in the external supplementary operation state, the combustible gas pre-stored in the gas storage tank 61 can enter the vertical combustion chamber 2 and the horizontal combustion chamber 4 under the action of the pumping device.
[0039] During the carbonization process, when the combustible gas generated by the carbonization of straw is recycled, the self-heating carbonization process of straw can be realized. At the same time, a certain amount of combustible gas (such as methane gas) is pre-stored in the gas storage tank 61, which can timely supplement energy for the carbonization process to cope with the situation of insufficient combustible gas.
[0040] Furthermore, in order to facilitate the addition of materials into the vertical carbonization chamber 1, a feed port 13 that can be opened and closed is provided at the top of the vertical carbonization chamber 1.
[0041] It can be understood that generally, the vertical feeding screw 11 is coaxially arranged with the vertical carbonization chamber 1. A first driving member 12 (such as a motor) is also provided outside the top of the vertical carbonization chamber 1, and the first driving member 12 is connected to the vertical feeding screw 11 to control the rotation and rotation speed of the screw. A second driving member 32 (such as a motor) is provided outside the end of the horizontal carbonization chamber 3, and the second driving member 32 is connected to the horizontal feeding screw 31 to control the rotation and rotation speed of the screw. Correspondingly, the feed port 13 should be eccentrically arranged. An air inlet hole is also provided at the top of the vertical carbonization chamber 1, and the aperture of this air inlet hole is relatively small.
[0042] During use, when the feed port 13 is opened and materials are added into the vertical carbonization chamber 1, then the feed port 13 is closed. During the carbonization process, a small amount of air can continuously enter the vertical carbonization chamber 1 through the air inlet hole to ensure that the pyrolysis gas generated by carbonization can smoothly enter the defocusing tank 62. An air path and a valve can also be eccentrically provided at the top of the vertical carbonization chamber 1 to adjust the reaction atmosphere.
[0043] In this embodiment, the two-stage continuous carbonization device further includes a crusher 7 for crushing materials, and the materials crushed by the crusher 7 can be put into the vertical carbonization chamber 1. Pretreating the straw with the crusher 7 before feeding can increase the processing capacity of the materials.
[0044] In an alternative embodiment, to facilitate the control of the discharge, a first discharge port is provided at the bottom end of the vertical carbonization chamber 1. The first discharge port is connected to the top of the first end of the horizontal carbonization chamber 3, and a first discharge valve 14 is provided on the first discharge port; a second discharge port is provided at the bottom of the side wall of the second end of the horizontal carbonization chamber 3. The second discharge port is connected to the top of the storage tank 5, and a second discharge valve 33 is provided on the second discharge port.
[0045] The inner walls of the first discharge port and the second discharge port preferably both have discharge guiding slopes. The inner walls of each discharge port are designed as inclined surfaces so that the carbonized materials can fall downward along the discharge guiding slopes under the action of gravity (fall into the horizontal carbonization chamber 3 or fall into the storage tank 5).
[0046] Furthermore, heat insulation layers 83 are wrapped around the outer walls of the vertical combustion chamber 2 and the horizontal combustion chamber 4, and air inlets 81 and smoke outlets 82 are provided on both the vertical combustion chamber 2 and the horizontal combustion chamber 4.
[0047] Generally, the air inlet 81 on the vertical combustion chamber 2 is provided at the bottom side wall of one side of the vertical combustion chamber 2, and the smoke outlet 82 is located at the top side wall of the other side of the vertical combustion chamber 2. The air inlet 81 of the horizontal combustion chamber 4 is provided at the bottom side wall of one end of the horizontal combustion chamber 4, and the smoke outlet 82 is located at the top side wall of the other end of the horizontal combustion chamber 4.
[0048] To facilitate the support and fixation of the vertical carbonization chamber 1 and the horizontal carbonization chamber 3, the two-stage continuous carbonization device further includes a base 9, a first bracket 91 and a second bracket. Both ends of the horizontal carbonization chamber 3 are fixedly connected to the base 9 through the first bracket 91, and the vertical carbonization chamber 1 is fixedly connected to the base 9 through the second bracket. The base 9 has a placement space, which can be used to place the above-mentioned storage tank 5 and crusher 7.
[0049] Generally, sealing flanges 42 are also provided at both ends of the horizontal carbonization chamber 3. The sealing flanges 42 are in contact with the outer wall of the horizontal carbonization chamber 3 to ensure the sealing of the horizontal carbonization chamber 3.
[0050] Self-locking universal wheels 92 can also be provided at the bottom of the base 9 to facilitate the movement of the entire carbonization device. Of course, other methods can also be used for the support and fixation of the carbonization chamber. This embodiment is only for illustration.
[0051] More specifically, taking straw as an example of the material, the carbonization process of the two-stage continuous carbonization device is as follows:
[0052] After being crushed by the crusher 7, the straw is fed into the feed inlet 13. The straw enters the vertical carbonization chamber 1. The stacking height of the moving bed is controlled to be 4 / 5 of the length of the vertical carbonization chamber 1. The materials in the vertical carbonization chamber 1 move downward under the continuous rotation of the vertical feeding screw 11. The first igniter 21 ignites and burns the combustible gas to supply energy for carbonization. The combustion-supporting gas enters from the air inlet 81 below the vertical combustion chamber 2, and the flue gas after combustion is discharged from the smoke outlet 82. Among them, the whole carbonization process adopts one-time feeding. After the feeding is completed, the feed inlet 13 is closed to ensure the sealing of the carbonization chamber. The materials are first carbonized in the vertical carbonization chamber 1 and then enter the horizontal carbonization chamber 3 for further carbonization reaction.
[0053] During the whole carbonization process, the combustible gas generated by carbonization is sent into the de-tarring tank 62 by the air pump 612. After removing tar, it enters the condensation tank 63 for condensation. The combustible gas after removing water vapor enters the gas storage tank 61, and then under the action of the air pump 612, it is sent into the vertical combustion chamber 2 and the horizontal combustion chamber 4 for combustion, realizing the self-circulation heating of the carbonization process.
[0054] After carbonizing for a certain time at high temperature, the straw is discharged. The carbonized straw slides down to the storage tank 5 under the action of gravity through the outlet guiding slope.
[0055] In summary, the two-stage continuous carbonization equipment in this embodiment is a movable two-stage continuous self-sustaining carbonization equipment, which solves the problems of scattered straw, low stacking density, difficult to collect and centrally process, difficult to transport and huge energy consumption for carbonization. The device has a simple structure, light weight, small footprint, and is convenient for carbonizing straw on the spot in the farmland. The vertical carbonization chamber 1 in the carbonization equipment adopts a moving bed design. The straw is pre-crushed by the crusher 7 and then pyrolytically carbonized, which greatly improves the straw processing capacity and working efficiency. At the same time, by storing the combustible flue gas generated by pyrolysis in the carbonization process in the gas storage tank 61 and introducing it into each combustion chamber for combustion during the carbonization process to supply heat for straw carbonization, the gas consumption is reduced; setting the gas storage tank 61 enables the device to realize self-heating carbonization of straw without external energy supply, adapting to portable on-site carbonization of straw; realizing the continuous carbonization process of straw, with high efficiency and low energy consumption in the pyrolytic carbonization process.
