Description

TECHNICAL FIELD

[0002] High temperature carbonization is the key procedure of preparing carbon composite material, generally, the tow material is sent into the carbonization furnace to carbonize, the carbonization furnace is equipped with low temperature zone (room temperature to 300 DEG C) from the tow entrance end to the export end, low temperature zone (300 DEG C to 500 DEG C), medium temperature zone (500 DEG C to 700 DEG C), high temperature zone (700 DEG C to 900 DEG C), high temperature zone (900 DEG C to 1300 DEG C), transition temperature zone (1300 DEG C to 1100 DEG C), cooling zone (1100 DEG C to 800 DEG C), cooling zone (800 DEG C to room temperature) in proper order, and different waste gas will be produced in each temperature zone.

[0003] The low temperature zone is mainly volatile organic compounds, such as alcohol, aldehyde, ketone, etc. ; the low temperature zone volatile organic compounds continue to volatilize but the quantity gradually reduces, and begins to produce carbon monoxide and carbon dioxide. The medium temperature zone carbon monoxide and carbon dioxide content increase. The high temperature zone is mainly carbon monoxide and carbon dioxide, and begins to produce a small amount of sulfide and nitrogen oxides. In the high temperature zone, carbon monoxide and carbon dioxide content reaches the peak, and sulfide and nitrogen oxides become the main pollutants. In the transition temperature zone, with the temperature beginning to drop, a small amount of metal oxides and silicate steam begin to condense to form particulate matter. In the cooling zone, with the temperature decreasing, the content of particulate matter such as metal oxides and silicates in the waste gas gradually increases, and the content of carbon monoxide and carbon dioxide slightly decreases. In the cooling zone, the waste gas is further cooled to form particulate matter such as carbon black and metal powder. If the waste gas pollutants produced in these temperature zones are not discharged in time, they will cause serious pollution to the carbonized material in the carbonization furnace.

[0004] In order to discharge the waste gas produced in different temperature zones during carbonization, an exhaust pipe is usually connected to the carbonization furnace to discharge the waste gas.

[0026] In order for those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] As shown in Figure 1 The utility model provides a kind of high-temperature carbonization device for carbon composite material preparation, including furnace body 1, furnace body 1 is provided with hearth 101, hearth 101 is sequentially separated into extremely low temperature zone 102, medium-low temperature zone 103, medium temperature zone 104, medium-high temperature zone 105, extremely high temperature zone 106, transition temperature zone 107, temperature decreasing zone 108, cooling zone 109 by partition plate 2 from wire bundle 12 inlet end to wire bundle 12 outlet end, furnace body 1 is provided with first treatment bin 5, second treatment bin 6 and third treatment bin 7, first treatment bin 5 is communicated with extremely low temperature zone 102, medium-low temperature zone 103, medium temperature zone 104 by first gas conveying pipe 501 respectively, second treatment bin 6 is communicated with medium-high temperature zone 105, extremely high temperature zone 106 by second gas conveying pipe 601 respectively, third treatment bin 7 is communicated with temperature decreasing zone 108, cooling zone 109 by third gas conveying pipe 701 respectively. Figure 1As shown by the A direction in the figure, the filament bundle 12 enters from the entrance end of the furnace 101 and is carbonized in turn through the extremely low-temperature zone 102 to the cooling zone 109. During the carbonization process, the volatile organic compounds and carbon monoxide and other pollutants generated by the extremely low-temperature zone 102, the medium-low-temperature zone 103, and the medium-temperature zone 104 are introduced into the first treatment bin 5 through the first gas conveying pipe 501 for treatment. The metal oxide, silicate, and other particulate suspensions generated by the extremely high-temperature zone 106 and the transition temperature zone 107, as well as the sulfide, nitrogen oxide, and other waste gas pollutants are introduced into the second treatment bin 6 through the second gas conveying pipe 601 for treatment. The carbon black, metal powder, and other particulate suspensions condensed in the transition temperature zone 107 to the cooling zone 109 are introduced into the third treatment bin 7 through the third gas conveying pipe 701 for treatment, so as to realize the classified and graded treatment of the waste gas pollutants and facilitate the improvement of the treatment efficiency and purification effect of the waste gas pollutants.

[0028] Specifically, as shown in the figure, Figure 2 the first treatment bin 5 is provided with a catalytic oxidation reactor 502 and an adsorption device 503. As a preferred arrangement, the catalytic oxidation reactor 502 is arranged near the outlet side of the first gas conveying pipe 501. First, the volatile organic compounds in the waste gas are treated by the adsorption device 503. The carbon monoxide in the waste gas passes through the adsorption device 503 and enters the catalytic oxidation reactor 502, where it is catalytically oxidized into harmless carbon dioxide and water, thereby realizing the purification and harmless treatment of the waste gas in the first treatment bin 5. As shown in the figure, Figure 3 the second treatment bin 6 is provided with a first dust remover 603 and a desulfurization and denitrification reactor 602. As a preferred arrangement, the desulfurization and denitrification reactor 602 is arranged near the outlet side of the second gas conveying pipe 601. First, the metal oxide, silicate, and other particulate suspensions in the second treatment bin 6 are removed by the first dust remover 603. Then, the sulfide, nitrogen oxide, and other waste gas pollutants are treated by the desulfurization and denitrification reactor 602. As shown in the figure, Figure 4 the third treatment bin 7 is internally provided with a second dust remover 702 to treat the carbon black, metal powder, and other particulate suspensions in the third treatment bin 7.

[0029] As shown in the figure, Figure 1 the first treatment bin 5, the second treatment bin 6, and the third treatment bin 7 are also connected with an exhaust pipe 8 for discharging the waste gas treated by the first treatment bin 5, the second treatment bin 6, and the third treatment bin 7.

[0030] As shown in the figure, Figure 1 and Figure 5As shown, the end wall of the furnace 101 and the partition plate 2 are both provided with through holes 13. An elastic sealing ring 201 is provided on the inner wall of the through hole 13. When the wire bundle 12 passes through the through hole 13, the elastic sealing ring 201 will be deformed by the compression of the wire bundle 12. This deformation makes the elastic sealing ring 201 and the wire bundle 12 fit tightly together, thereby effectively preventing the exhaust gas in the furnace 101 from flowing out through the gap.

[0031] like Figure 1 As shown, a controller 11 is installed outside the furnace body 1. The controller 11 stores preset temperature values ​​and temperature monitoring programs for the ultra-low temperature zone 102 to the cooling zone 109. Each of the ultra-low temperature zone 102 to the cooling zone 109 within the furnace chamber 101 is equipped with a heating device 9 and a temperature sensor 10, which are electrically connected to the controller 11. The actual temperature within the ultra-low temperature zone 102 to the cooling zone 109 is monitored in real time by the temperature sensor 10, and the monitoring results are fed back to the controller 11. The controller 11 instructs the heating device 9 within the ultra-low temperature zone 102 to the cooling zone 109 to provide heat, ensuring that the temperature within the ultra-low temperature zone 102 to the cooling zone 109 remains near the preset value, thereby improving the heating effect during the carbonization process of the carbon composite material.

[0032] like Figure 1 As shown, the high-temperature carbonization device for preparing carbon composite materials also includes a surface treatment device 3 connected to the outlet end of the filament bundle 12 in the furnace 101 and an inert gas supply system 4 connected to the furnace body 1. One end of the surface treatment device 3 is sleeved on the outside of the end wall of the furnace 101. The surface treatment device 3 can clean the impurities, oil stains and other substances attached to the surface of the carbonized filament bundle 12.

[0033] The inert gas supply system 4 includes a gas supply device 401 and a gas supply heating device 402 connected to the gas supply device 401. One end of the gas supply device 401 is connected to the surface treatment device 3 through a low-temperature gas supply pipe 403, and can inject inert protective gases such as nitrogen into the surface treatment device 3 in a direction opposite to the advancing direction of the fiber bundle 12. The flow direction of the inert protective gas is as follows: Figure 1 As shown in direction B, this prevents the filament bundle 12 inside the surface treatment device 3 from being oxidized by air, thereby ensuring the surface quality of the filament bundle 12. The other end of the gas supply device 401 is connected to the gas supply heating device 402 through the gas pipe 405. The gas supply heating device 402 is connected to a high-temperature gas supply pipe 404, which is connected to the extremely low temperature zone 102 to the cooling zone 109 inside the furnace 101. After the inert protective gas is heated by the gas supply heating device 402, it is injected into each temperature zone inside the furnace 101, so that the flow direction of the inert protective gas in each temperature zone is opposite to the forward direction of the filament bundle 12, thereby preventing the filament bundle 12 from being oxidized and corroded inside the furnace 101 and ensuring the carbonization quality of the filament bundle 12.
