[0021] Coal is used as a reaction raw material to make carbon-containing substances such as activated carbon. This reaction needs to be carried out in a carbonization furnace, and the furnace chamber of the carbonization furnace is mainly used to hold the raw materials to be processed. Existing carbonization furnaces generally process materials of similar volumes in the same carbonization furnace. Therefore, before processing, the raw materials need to be classified according to preset size specifications, and this separate classification operation affects the practicality of the carbonization furnace. Therefore, the embodiments of the present utility model provide a carbonization furnace chamber to solve the problem that existing carbonization furnaces cannot be compatible with reaction raw materials of different specifications.

[0022] The present utility model provides a carbonization furnace chamber, such as Figures 1 to 3As shown in the figure, the cavity of the furnace chamber includes a material distribution device. The material distribution device is provided with multiple levels of cloth layers 10 in a layered manner, and the distances between the levels of the multiple levels of cloth layers 10 are distributed with variable spacing. The cloth layer 10 includes material passing holes with a preset diameter, and the diameters of the material passing holes on different cloth layers 10 decrease successively from top to bottom. The cloth layer 10 includes an upper material passing plate 4 and a lower material distributing plate 5. The material distributing plate 5 is inclined relative to the material passing plate 4, and the extending end of the material distributing plate 5 leads into a carbonization chamber at the bottom layer of the material distribution device. The carbonization chamber includes a primary carbonization chamber 1, a secondary carbonization chamber 2, and a tertiary carbonization chamber. The area between the carbonization chambers is a combustion chamber 3. The primary carbonization chamber 1, the secondary carbonization chamber 2, and the tertiary carbonization chamber are arranged to load materials with different particle ranges classified by the material distribution device.

[0023] As described above, the cavity of the furnace chamber of the carbonization furnace provided by the present utility model includes a material distribution device. The material distribution device is provided with multiple levels of cloth layers 10 in a layered manner, and the distances between the levels of the multiple levels of cloth layers 10 are distributed with variable spacing. The cloth layer 10 includes material passing holes with a preset diameter, and the diameters of the material passing holes on different cloth layers 10 decrease successively from top to bottom. The cloth layer 10 classifies the materials entering the cavity of the carbonization furnace and sends the different types of materials into the carbonization chamber below the material distribution device. The corresponding carbonization chambers include a primary carbonization chamber 1, a secondary carbonization chamber 2, and a tertiary carbonization chamber. And the three types of carbonization chambers are arranged to load materials with different particle ranges classified by the material distribution device. The area between each carbonization chamber is a combustion chamber 3, that is, the heat source for heating each carbonization chamber is arranged between the carbonization chambers, which can improve the thermal efficiency of the carbonization chamber. The main point is that the material distribution device in the cavity classifies the materials and distributes them in different carbonization chambers according to the types. The classified materials are then classified and processed, thereby improving the practicability of the carbonization furnace.

[0024] Specifically, as Figure 3 shown, the cloth layer 10 of the material distribution device includes an upper material passing plate 4 and a lower material distributing plate 5. The material distributing plate 5 is inclined relative to the material passing plate 4, and the extending end of the material distributing plate 5 leads into a carbonization chamber at the bottom layer of the material distribution device. That is, the upper material passing plate 4 drops the particulate materials that can pass through it onto the lower material distributing plate 5, and the material distributing plate 5 directly sends the passing materials into the carbonization chamber for placing materials of this specification; or the material distributing plate 5 sends the passing materials onto the next upper material passing plate 4 for further classification, and the material distributing plate 5 directly sends the materials remaining on the upper material passing plate 4 into the carbonization chamber for placing materials of this specification. That is, it can be classified once, or it can be divided into materials step by step multiple times.

[0025] Among them, two adjacent first-stage carbonization chambers 1 are distributed at a first preset interval, two second-stage carbonization chambers 2 are distributed at a second preset interval, and two third-stage carbonization chambers are distributed at a third preset interval. The combustion chamber 3 is a cavity for heating the carbonization chamber at the first preset interval, the second preset interval, and the third preset interval. The first-stage carbonization chamber 1, the second-stage carbonization chamber 2, and the third-stage carbonization chamber have the same size and all include an ellipsoidal dome; the first preset interval, the second preset interval, and the third preset interval are the same, increasing, or decreasing.

[0026] In this embodiment, the size of the combustion chamber 3 is the interval between two adjacent carbonization chambers. The size of the combustion chamber 3 is related to the range of material particles in the two carbonization chambers. If the first interval, the second interval, and the third interval are equal, the particles in the corresponding different carbonization chambers are quite the same; if the first interval, the second interval, and the third interval increase or decrease gradually, it means that there is a certain gap between the particles in the corresponding carbonization chambers, and the size of this gap is related to the size of the gap between the material particles in the carbonization chamber. Because, for materials with larger particles, more heat is required for carbonization treatment than for materials with smaller particles. Therefore, a larger interval should be set between the carbonization chambers storing larger-particle materials so that more heat sources can heat the carbonization chambers of this part of larger-particle materials. Specifically, the aforementioned decreasing relationship can be adjusted according to the actual distribution of the carbonization chambers and the particle size of the material to be processed.

[0027] Among them, the aforementioned first-stage carbonization chamber 1 and / or second-stage carbonization chamber 2 and third-stage carbonization chamber are made of second-grade high-aluminum bricks. This kind of brick is a refractory brick mainly composed of alumina, and it has the advantages of small high-temperature creep, strong erosion resistance, good thermal shock stability, etc., which can improve the performance and service life of the carbonization chamber.

[0028] In some embodiments, there is a roof space between the dome of the carbonization chamber and the coal raw material in the carbonization chamber, and there are fire holes on the wall of the carbonization chamber at the roof space. In this embodiment, the ellipsoidal dome design can reduce the deposition of particulate impurities in the gas. Even if some impurities fall off, they will slide into the carbonization chamber or the combustion chamber 3 under the action of gravity. On the other hand, the ellipsoidal dome can form a heat eddy current, making the heat in the carbonization chamber not easy to dissipate and improving the processing effect of the carbonization chamber. The fire holes can be used to introduce oxygen and can also be used as observation holes for observing the inside of the combustion chamber 3.

[0029] In some embodiments, the present utility model further includes a heating base 6, a smoke exhaust port, and a riser pipe. The heating base 6 is detachably connected to the combustion chamber 3. The heating base 6 is configured to place fuel and feed the fuel into the combustion chamber 3. The riser pipe is docked with the smoke exhaust port, and the smoke exhaust port is provided on the side wall of the carbonization chamber or at the ellipsoidal dome. The coal after carbonization treatment is made into activated carbon or other products, and these products are taken out from the inner part of the bottom heating base 6 when the combustion is completed.

[0030] In some embodiments, an expanded coke discharging pipe is further included. The coke discharging pipe is arranged at the bottom of the aforementioned heating base 6, and a coke discharging tank is further included outside the coke discharging pipe. Tar is a common by-product in the coal treatment process. Some components in the gas will become tar after the gas is pre-cooled or oxidized and cleaned. This part of tar needs to be discharged from the equipment. Generally, it sinks to the bottom and automatically stores in the coke discharging tank after flowing out from the bottom of the equipment, and can be reused in related processes such as asphalt production.

[0031] It can also be implemented that the aforementioned primary carbonization chamber 1, secondary carbonization chamber 2, and tertiary carbonization chamber all include multiple ones. The multiple primary carbonization chambers 1, secondary carbonization chambers 2, and tertiary carbonization chambers are arranged in an array distribution. The multiple carbonization chambers can further improve the efficiency of the carbonization furnace treatment.

[0032] In addition, a first air inlet pipe and a second air inlet pipe are provided outside the furnace body of the carbonization furnace. The first air inlet pipe is configured to be communicated with the air outlet pipe of the filter dust collector, and the second air inlet pipe is connected to an air pump and is configured to supplement the combustion medium into the carbonization chamber. In addition, a mixing chamber can be further included. The mixing chamber is arranged outside the furnace body of the retort furnace. The first air inlet pipe and the second air inlet pipe enter from the air inlet end of the mixing chamber, and the mixed gas flows out from the air outlet of the mixing chamber and is introduced into the carbonization furnace. By providing the mixing chamber, the gas and air can be mixed evenly before entering the retort furnace, avoiding affecting the treatment quality due to uneven mixing of gas and oxygen in the carbonization chamber. That is, this design improves the quality of coal treatment.

[0033] Finally, the carbonization furnace chamber provided by the present utility model has a material distribution device in its cavity. The material distribution device is provided with multiple levels of cloth layers 10 in a layered manner, and the distances between the levels of the multiple levels of cloth layers 10 are distributed with variable distances; the cloth layer 10 includes material passing holes with a preset diameter, and the diameters of the material passing holes on different cloth layers 10 from top to bottom decrease in sequence; the cloth layer 10 includes an upper material passing plate 4 and a lower material distributing plate 5, the material distributing plate 5 is inclined relative to the material passing plate 4, and the extending end of the material distributing plate 5 leads into the carbonization chamber at the bottom of the material distribution device. The carbonization chamber includes multiple first-level carbonization chambers 1, second-level carbonization chambers 2, and third-level carbonization chambers. The area between the carbonization chambers is a combustion chamber 3. The first-level carbonization chambers 1, second-level carbonization chambers 2, and third-level carbonization chambers are arranged to load materials with different particle ranges classified by the material distribution device. The present utility model improves the practicability of the carbonization furnace in processing materials and solves the problem of incompatibility of the carbonization furnace in the prior art.
