Description

Technical Field

[0001] The utility model relates to the technical field of carbonization treatment, in particular to a tar carbonization furnace for high-volatile raw materials induced by airflow organization. Background Art

[0002] The new energy industry often requires heat treatment of materials with high volatile content to adjust their composition and structure. During the heat treatment process, the volatiles are rapidly released, accompanied by reactions such as dehydration, ring opening, and dehydrogenation. Various products are often generated during this process, including small-molecule gaseous products such as water, CO, CO₂, and H₂, as well as polymers such as tar produced by the condensation of high-molecular-weight organic compounds. These small-molecule gaseous products can be discharged from the furnace along with the inert gas flow. However, tar, due to its high molecular weight, high boiling point, and high viscosity, often adheres to the furnace and piping, causing damage to heat treatment equipment and requiring frequent downtime for tar removal, resulting in low production efficiency. Utility Model Content

[0019] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] Example 1

[0021] See also Figure 1-3 : A tar carbonization furnace for high-volatile raw materials induced by air flow organization, comprising a furnace body 1, a semi-open trough furnace core 101 is provided in the furnace body 1, a auger screw conveyor 102 is installed on the semi-open trough furnace core 101, and a thermocouple 103 is installed below the semi-open trough furnace core 101; air inlets 104 are provided on both sides of the bottom of the furnace body 1, a herringbone tar collecting plate 2 is provided on the upper part of the furnace body 1, exhaust interlayers 3 are provided on both sides below the herringbone tar collecting plate 2, and exhaust ports 105 are provided at the ends of the exhaust interlayer 3.

[0022] In this embodiment, air inlets are provided below the furnace body on both sides of the tar production section, and exhaust interlayers are provided on both sides below the herringbone tar collecting plate. Air flow enters from below the furnace body on both sides, is guided by the exhaust interlayers on both sides below the herringbone tar collecting plate, and is discharged through the exhaust ports. Most of the tar gas generated by the material at this stage is directly taken out of the furnace body through the exhaust interlayer, thus avoiding large-scale condensation of tar in the furnace body.

[0023] It should be noted that this embodiment adopts a semi-open trough-type furnace, and uses an auger screw conveyor to transport and tumble the material to ensure uniform heating of the material and sufficient emission of volatile matter.

[0024] In a specific example, a flame decoker 4 is spaced apart on the top of the herringbone tar collecting plate 2 .

[0025] In this embodiment, the flame decokers are arranged at intervals on the top of the herringbone tar collecting plates, which can be used to decoke the tar condensed on the surface of the collecting plates, thereby improving the tar treatment efficiency; preventing the tar from sticking and clogging in the furnace body or dropping contaminating materials, reducing the frequency of shutdowns for maintenance, and effectively improving the production efficiency of the kiln.

[0026] In a specific example, a reinforcing rib 301 is provided in the exhaust interlayer 3 .

[0027] In this embodiment, the strength of the exhaust interlayer is improved by reinforcing ribs.

[0028] In a specific example, tar collecting tanks 5 are provided on both sides below the exhaust interlayer 3 .

[0029] It should be noted that the tar is captured by the herringbone tar collecting plates, and part of it can flow along the collecting plates into the tar collecting tanks on both sides below the exhaust interlayer, further improving the tar treatment efficiency.

[0030] In a specific example, the semi-open trough-type furnace 101 is tilted, the relatively high front end is connected to the feeding port 106, and the relatively low rear end is connected to the discharging port 107. The outer layer of the furnace body 1 is provided with an insulation layer.

[0031] The furnace of this embodiment has a certain inclination angle, which is beneficial to the transmission of materials from the feed port to the discharge port. The insulation layer can prevent the temperature inside the furnace from dissipating, thereby improving the carbonization efficiency of the material.

[0032] The working principle of this embodiment is as follows: a herringbone tar collecting plate is installed above the semi-open trough furnace, a flame decoker is arranged at intervals on the top, and an exhaust interlayer is provided at the lower ends of both sides of the bottom, and the ends of the exhaust interlayer are connected to the exhaust port of the furnace body. When the material is conveyed to the tar release area in the furnace body by the auger screw conveyor, an inert gas flows into the trough furnace body through the air inlets on both sides of the bottom of the furnace body, fully purges the material, and brings the tar gas generated by the material from bottom to top to the exhaust interlayer below the herringbone tar collecting plate. Most of the tar gas is discharged through the exhaust port; the remaining tar is captured by the herringbone tar collecting plate and can flow along the inclined tar collecting plate into the tar collection tanks on both sides of the bottom of the furnace body; the tar condensed on the herringbone tar collecting plate for a long time can be ignited and removed by the flame decoker.

[0033] Example 2

[0034] To achieve the above purpose, see Figure 4-6 : This embodiment also discloses a tar carbonization furnace for high-volatile raw materials induced by air flow organization, comprising a furnace body 1, a semi-open trough furnace core 101 is provided in the furnace body 1, a auger screw conveyor 102 is installed on the semi-open trough furnace core 101, and a thermocouple 103 is installed below the semi-open trough furnace core 101; air inlets 104 are provided on both sides of the bottom of the furnace body 1, a herringbone tar collecting net 6 is provided on the upper part of the furnace body 1, tar grooves 7 are provided at the ends of the lower sides of the herringbone tar collecting net 6, and an air outlet 108 is provided on the top of the herringbone tar collecting net 6.

[0035] When the material is conveyed to the tar release area in the furnace through the auger screw conveyor, the inert gas flows into the semi-open trough furnace through the air inlet at the bottom of the furnace body, fully purges the material, and brings the tar generated by the material from bottom to top onto the herringbone tar collection net; the captured tar flows along the inclined tar collection net to the tar tank, and the other part of the tar gas is discharged through the air outlet at the top.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
