[0003] However, during the final reaction of carbon coating, due to the accumulation of carbon source gas and intermediate products of carbon source gas cracking, the tar formed by polymerization easily causes agglomeration between particles, reducing the quality of products that require carbon source gas cracking and carbon coating, making the product quality unable to meet the standard requirements. In addition, after the tar is formed, the carbon coating equipment needs to be shut down to passively treat the tar. Frequent shutdowns for cleaning of the carbon coating equipment not only shorten the service life of the carbon coating equipment, but also reduce the production efficiency of the product.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] The following specific embodiments are used to describe the technical solution of the present invention in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0016] Figure 1 This is a flow chart of a tar suppression method provided by an embodiment of the present invention. The method can be performed by a tar suppression device, which can be implemented in software and / or hardware. In a specific embodiment, the device can be integrated into an electronic device, such as a computer, a server, etc. The following embodiments will be described using the device integrated into an electronic device as an example. Figure 1 , the method may specifically include the following steps: Step 101: Obtain first traffic.

[0017] The first flow rate is the flow rate of the carbon source gas at the inlet of the carbon coating device. The carbon coating device can be understood as specialized equipment used to carbon-coat various materials. The carbon source gas can include gaseous carbon sources such as acetylene, methane, and propylene. In other embodiments, the carbon source gas can also include other gaseous carbon sources besides those mentioned above.

[0018] In one embodiment, the first flow rate can be directly obtained from the carbon coating device. .

[0019] Step 102 : After a preset time period, the gas composition of the carbon source gas in the total gas at the exhaust end of the carbon coating device is detected to obtain the exhaust end carbon source gas ratio.

[0020] The preset time can be understood as the time that the rotary kiln needs to run after the gas for the carbon coating reaction is introduced into the air inlet of the carbon coating equipment. Figure 2As shown, the carbon coating equipment may include an air inlet end, a rotary kiln, a rotating motor, a bracket, an exhaust end, a gas composition ratio detection device, a glass tube, an exhaust gas treatment pipe, an exhaust end gas flow detection device, and an exhaust gas treatment device. The air inlet end is connected to the rotary kiln. The exhaust end of the rotary kiln is connected to the glass tube and the exhaust gas treatment pipe respectively. The glass tube is connected to the gas composition ratio detection device. The exhaust gas treatment pipe is connected to the exhaust end gas flow detection device. The exhaust gas treatment pipe can also be connected to the exhaust gas treatment device to transfer the total gas at the exhaust end to the exhaust gas treatment device for exhaust gas treatment. The gas used for the carbon coating reaction can be introduced into the rotary kiln through the air inlet end. The rotary kiln is rotated by the motor to perform carbon coating. The gas after the carbon coating reaction is then discharged through the exhaust end. When the total gas is discharged from the exhaust end, part of the total gas at the exhaust end is transferred to the gas composition ratio detection device using the glass tube, so that the gas composition ratio detection device detects the gas composition of the carbon source gas in the total gas at the exhaust end and obtains the proportion of the carbon source gas at the exhaust end. The exhaust end total gas is transmitted to the exhaust end gas flow detection device by using the exhaust gas treatment pipe, so that the exhaust end gas flow detection device detects the flow of the exhaust end total gas.

[0021] In one embodiment, detecting the gas composition of the carbon source gas in the total gas at the exhaust end of the carbon-coated device to obtain the exhaust end carbon source gas ratio can include: using a glass tube to obtain a preset ratio of the total gas at the exhaust end from the exhaust end and transmitting the preset ratio of the gas to a gas composition ratio detection device; using the gas composition ratio detection device to detect the gas composition of the carbon source gas in the total gas at the exhaust end of the carbon-coated device to obtain the exhaust end carbon source gas ratio. In this way, the exhaust end carbon source gas ratio in the total gas at the exhaust end can be accurately detected through the cooperation of the glass tube and the gas composition ratio detection device, thereby improving the accuracy of the exhaust end carbon source gas ratio.

[0022] The preset gas ratio can be understood as a portion of the preset total gas at the exhaust end. The carbon source gas ratio at the exhaust end can be understood as the component ratio of the carbon source gas in the total gas at the exhaust end. The total gas at the exhaust end can be understood as the gas discharged from the exhaust end of the rotary kiln.

[0023] For example, the effective gas volume of the carbon coating equipment can be 150L. The single loading of the carbon coating material is 5kg. The total gas flow rate into the rotary kiln can be preset to 5L / min. The carbon source gas is acetylene. The vapor-deposited silicon material can be placed in Figure 2 The bottom of the rotary kiln is shown, and then nitrogen protective gas is introduced through the air inlet end and the chamber air of the rotary kiln is exhausted. Figure 2 The rotating motor in the Figure 2 The rotary kiln in the furnace rotates and the chamber temperature of the rotary kiln is increased to perform carbon coating (for example, the chamber temperature can be 600°C). Finally, the total gas is introduced into the rotary kiln through the gas inlet. After the rotary kiln has been running for a preset time, the rotary kiln is heated by the gas inlet. Figure 2Medium glass tube, from Figure 2 The exhaust end shown in FIG. obtains a preset proportion of the total gas at the exhaust end and transmits the preset proportion of gas to the exhaust end. Figure 2 The gas composition ratio detection equipment shown in the figure is used to detect the gas composition of acetylene in the total gas at the exhaust end of the carbon packaging equipment, and the acetylene ratio at the exhaust end is obtained. .

[0024] Step 103: Detect the second flow rate.

[0025] The second flow rate is the flow rate of the total gas at the exhaust end of the carbon coating equipment.

[0026] In one embodiment, detecting the second flow rate may include: using the exhaust gas treatment pipe to transmit the total exhaust gas at the exhaust end to the exhaust end gas flow detection equipment; using the exhaust end gas flow detection equipment to detect the flow rate of the total exhaust end gas to obtain the second flow rate, so that the second flow rate can be accurately detected by the exhaust end gas flow detection equipment set on the exhaust gas treatment pipe, thereby improving the accuracy of the second flow rate.

[0027] In this embodiment, the exhaust gas flow detection device can be a flow meter, which can be installed at any location in the exhaust gas treatment pipe. Because the flow meter is relatively small, replacing the exhaust gas flow detection device with a flow meter can, on the one hand, reduce the size of the carbon coating equipment. On the other hand, the flow meter can accurately and quickly detect the second flow rate, thereby improving the detection speed and accuracy of the second flow rate.

[0028] For example, you can use Figure 2 The exhaust gas treatment pipe in the exhaust end transmits the total gas at the exhaust end to Figure 2 The exhaust end gas flow detection device is used to detect the flow of the total gas at the exhaust end, and the second flow is obtained. .

[0029] Step 104 : determining the real-time conversion rate of the carbon source gas according to the first flow rate, the second flow rate, and the ratio of the carbon source gas at the exhaust end.

[0030] Among them, the real-time conversion rate can be understood as the instantaneous ratio of carbon source gas converted into effective coated carbon during the carbon coating process.

[0031] In one embodiment, determining the real-time conversion rate of the carbon source gas based on the first flow rate, the second flow rate and the ratio of the carbon source gas at the exhaust end may include: using a real-time conversion rate model to determine the real-time conversion rate of the carbon source gas based on the first flow rate, the second flow rate and the ratio of the carbon source gas at the exhaust end.

[0032] The real-time conversion rate model is as follows: ; in, Indicates the real-time conversion rate of carbon source gas, Indicates the first flow, Indicates the second flow rate, Indicates the proportion of carbon source gas at the exhaust end.

[0033] For example, the carbon source gas is acetylene. The first flow rate is The second flow rate is The ratio of carbon source gas at the exhaust end is The first flow can be directly The second flow rate is , the ratio of carbon source gas at the exhaust end is , substitute into the real-time conversion rate model to calculate the real-time conversion rate of acetylene .

[0034] In a specific embodiment, the gas composition ratio detection device may be a gas chromatograph or a tunable diode laser absorption spectrometer. In other embodiments, the gas composition ratio detection device may also be other devices capable of detecting the gas composition of the carbon source gas in the total gas at the exhaust end of the carbon coating device, and this embodiment does not impose any specific limitations on this.

[0035] Step 105: Adjust the carbon coating parameters based on the real-time conversion rate to suppress the generation of tar during the carbon coating process.

[0036] The carbon coating parameter may include a current chamber temperature, which may be understood as the current chamber temperature of the rotary kiln.

[0037] When the real-time conversion rate of the carbon source gas is equal to a certain threshold, during the process of the current chamber temperature being reduced to the preset chamber temperature, gaseous tar can be generated in the rotary kiln without generating solid tar, that is, the current chamber temperature can be adjusted to the preset chamber temperature, thereby generating gaseous tar and suppressing the generation of solid tar. Therefore, in one embodiment, based on the real-time conversion rate, adjusting the carbon coating parameters of the carbon coating to suppress the generation of tar during the carbon coating process can include: when the real-time conversion rate is equal to the first preset conversion rate, reducing the current chamber temperature to the preset chamber temperature to suppress the generation of tar during the carbon coating process. In this way, when the real-time conversion rate of the carbon source gas is equal to the first preset conversion rate, by reducing the current chamber temperature to the preset chamber temperature, the generation of solid tar can be suppressed, and the generated gaseous tar can be discharged through the exhaust end, thereby improving the product quality of the product, reducing the number of times the carbon coating equipment is shut down to passively process tar, and eliminating the need for frequent shutdowns to clean the carbon coating equipment, which not only extends the service life of the carbon coating equipment, but also improves the production efficiency of the product.

[0038] The first preset conversion rate may be understood as a preset acetylene conversion rate for extending the duration of the gaseous tar.

[0039] like Figure 3 As shown in the figure, when the carbon coating reaction was carried out for 300 minutes, the conversion rate of acetylene was 18%. When the carbon coating reaction was carried out for 326 minutes, the conversion rate of acetylene was 16.7%, which is the critical conversion rate of acetylene when solid tar was produced at a chamber temperature of 590℃. Figure 4 It can be seen that the critical conversion rate of acetylene is related to the chamber temperature. As the chamber temperature decreases, the critical conversion rate of acetylene also decreases. When the chamber temperature is below 560℃, the cracking rate of acetylene is reduced, and a large amount of acetylene gas and processing time are consumed, which is not conducive to industrial application. When the carbon coating temperature is above 630℃, the high temperature will lead to an increase in product side reactions, and the tar formation process will be more sudden and uncontrollable, which is not conducive to industrial application. Please refer to Figure 5 At 590°C, the critical acetylene conversion rate barely changes with acetylene flow rate, remaining at 16.7% ± 0.1%. Therefore, when the real-time acetylene conversion rate slightly exceeds the critical conversion rate of 16.7%, the chamber temperature can be adjusted to 570°C, where gaseous tar production can continue. This extends the duration of gaseous tar production and suppresses the formation of solid tar. For example, the first preset conversion rate could be 18%.

[0040] For example, the carbon source gas is acetylene. The first preset conversion rate is 18%. The current chamber temperature is 590°C. The preset chamber temperature is 570°C. That is, when the real-time acetylene conversion rate reaches the first preset conversion rate of 18%, the current chamber temperature of 590°C is lowered to the preset chamber temperature of 570°C to suppress tar formation during the carbon coating process.

[0041] When the real-time conversion rate of the carbon source gas reaches a certain threshold, the flow rate of the carbon source gas at the intake end can be reduced. When the flow rate of the carbon source gas is reduced, the concentration of hydrocarbons in the reaction system decreases, and the probability of collisions between molecules per unit volume decreases, resulting in a slowdown in the polymerization reaction rate between free radicals, thereby reducing the total amount of tar generated, thereby achieving the purpose of suppressing tar formation. Therefore, in another embodiment, the carbon coating parameter may also include the first flow rate and a third flow rate of the total gas at the intake end. The total gas at the intake end can be understood as all gases used for the carbon coating reaction. The total gas at the intake end may include the carbon source gas. Adjusting the carbon coating parameters based on the real-time conversion rate to suppress the generation of tar during the carbon coating process may include: when the real-time conversion rate is equal to the second preset conversion rate, maintaining the third flow rate unchanged and reducing the first flow rate to suppress the generation of tar during the carbon coating process. This can reduce the flow rate of the carbon source gas at the inlet end by maintaining the third flow rate of the total gas at the inlet end unchanged, thereby reducing the concentration of hydrocarbons in the reaction system, thereby reducing the probability of collision between molecules per unit volume, slowing down the polymerization reaction rate between free radicals, and thus reducing the total amount of tar generated, thereby achieving the purpose of suppressing the generation of tar. In addition, by suppressing the generation of tar, the number of times the carbon coating equipment is shut down for passive tar treatment is reduced, and there is no need to frequently shut down the carbon coating equipment for cleaning, which not only extends the service life of the carbon coating equipment, but also improves the production efficiency of the product.

[0042] The second preset conversion rate can be understood as the critical conversion rate of acetylene when the carbonization reaction begins to produce solid tar at the preset chamber temperature. The second preset conversion rate is lower than the first preset conversion rate.

[0043] For example, the carbon source gas is acetylene. The second preset conversion rate is 11.4%. The current chamber temperature is 570°C. The third flow rate is 5 L / min. The first flow rate of acetylene at the current time is 2 L / min. That is, when the real-time acetylene conversion rate equals the second preset conversion rate of 11.4%, the third flow rate of the total gas at the inlet end is maintained at 5 L / min, and the first flow rate of acetylene is reduced to 0.5 L / min to continue the carbon coating reaction until solid tar is produced. The carbon coating reaction is then stopped, thereby suppressing the formation of tar during the carbon coating process.

[0044] In another embodiment, based on the real-time conversion rate, the carbon coating parameters of the carbon coating are adjusted to suppress the generation of tar during the carbon coating process, which may include: when the real-time conversion rate is equal to the first preset conversion rate, reducing the current chamber temperature to the preset chamber temperature; when the real-time conversion rate is equal to the second preset conversion rate, keeping the third flow rate unchanged and reducing the first flow rate to suppress the generation of tar during the carbon coating process. That is, the suppression of tar generation is divided into two stages. Among them, the first stage is: when the real-time conversion rate is equal to the first preset conversion rate, reducing the current chamber temperature to the preset chamber temperature. That is, when the real-time conversion rate of the carbon source gas is equal to the first preset conversion rate, by reducing the current chamber temperature to the preset chamber temperature, the generation of solid tar is suppressed, and the generated gaseous tar can be discharged through the exhaust end, thereby improving the product quality of the product. The second stage is: when the real-time conversion rate is equal to the second preset conversion rate, keeping the third flow rate unchanged and reducing the first flow rate. That is, by maintaining the third flow rate of the total gas at the inlet end unchanged, reducing the flow rate of the carbon source gas at the inlet end, and reducing the concentration of hydrocarbons in the reaction system, the probability of collisions between molecules per unit volume is reduced, slowing the polymerization reaction rate between free radicals, thereby reducing the total amount of tar generated, thereby achieving the purpose of inhibiting tar formation. In addition, by inhibiting tar formation in the above two stages, the number of times the carbon coating equipment is shut down for passive tar treatment is reduced, eliminating the need for frequent shutdowns for cleaning of the carbon coating equipment, which not only extends the service life of the carbon coating equipment but also improves product production efficiency.

[0045] For example, the carbon source gas is acetylene. The first preset conversion rate is 18%. The second preset conversion rate is 11.4%. The current chamber temperature is 590°C. The preset chamber temperature is 570°C. The third flow rate is 5L / min. The first flow rate of acetylene at the current time is 2L / min. When the real-time conversion rate of acetylene is equal to the first preset conversion rate of 18%, the current chamber temperature is reduced from 590°C to the preset chamber temperature of 570°C to suppress the formation of tar during the carbon coating process. When the real-time conversion rate of acetylene is equal to the second preset conversion rate of 11.4%, the third flow rate of the total gas at the inlet end is kept unchanged at 5L / min, and the first flow rate of acetylene is reduced to 0.5L / min for the carbon coating reaction until solid tar is produced, and the carbon coating reaction is stopped, thereby achieving the purpose of suppressing the formation of tar during the carbon coating process.

[0046] Please refer to Figure 6 When the tar suppression method is not used, a large amount of tar is produced during the carbonization process, causing the material to stick together. Figure 7 , the large amount of tar produced leads to pipeline blockage, and the carbonization reaction is forced to terminate. At this time, the material has a large specific surface area. Please refer to Figure 8 After adopting the tar suppression method provided by the embodiment of the present invention, the tar production in the carbon coating process is suppressed and the degree of material adhesion is greatly reduced. Figure 9 , the specific surface area of ​​the material is reduced.

[0047] In an embodiment of the present invention, a first flow rate is obtained, which is the flow rate of the carbon source gas at the inlet end of the carbon coating device; after a preset time period, the gas composition of the carbon source gas in the total gas at the exhaust end of the carbon coating device is detected to obtain the carbon source gas ratio at the exhaust end; a second flow rate is detected, which is the flow rate of the total gas at the exhaust end of the carbon coating device; the real-time conversion rate of the carbon source gas is determined based on the first flow rate, the second flow rate, and the carbon source gas ratio at the exhaust end; and the carbon coating parameters are adjusted based on the real-time conversion rate to suppress the generation of tar during the carbon coating process. That is, the real-time conversion rate of the carbon source gas is determined based on the first flow rate, the second flow rate, and the carbon source gas ratio at the exhaust end, and then the real-time conversion rate of the carbon source gas is associated with the carbon coating parameters. The carbon coating parameters are adjusted based on the real-time conversion rate of the carbon source gas to suppress the generation of tar during the carbon coating process, reduce the agglomeration effect between particles easily caused by the tar formed by polymerization, improve the quality of products that require carbon source gas cracking and carbon coating, and make the product quality meet the standard requirements.

[0048] In addition, since tar formation is suppressed, the number of times the carbon coating equipment is shut down for passive tar treatment is reduced, and there is no need to frequently shut down the carbon coating equipment for cleaning. This not only extends the service life of the carbon coating equipment, but also improves the production efficiency of the product.

[0049] The tar suppression method provided by the embodiment of the present invention is further described below. Figure 10 As shown, Figure 10 This is another flow chart of the tar inhibition method provided by an embodiment of the present invention, which may specifically include the following steps: Step 201: Obtain first traffic.

[0050] Step 202 : After a preset time, a preset proportion of the total gas at the exhaust end is obtained from the exhaust end by using a glass tube and the preset proportion of the gas is transmitted to a gas composition ratio detection device.

[0051] Step 203 : using a gas composition ratio detection device to detect the gas composition of the carbon source gas in the total gas at the exhaust end of the carbon packaging device, and obtaining the exhaust end carbon source gas ratio.

[0052] In step 204 , the exhaust end total gas of the exhaust end is transmitted to the exhaust end gas flow detection device by using the exhaust gas treatment pipe.

[0053] Step 205: Detect the flow of the total gas at the exhaust end using the exhaust end gas flow detection equipment to obtain a second flow.

[0054] Step 206 : Determine the real-time conversion rate of the carbon source gas according to the first flow rate, the second flow rate, and the ratio of the carbon source gas at the exhaust end using a real-time conversion rate model.

[0056] Step 208 : Lowering the current chamber temperature to a preset chamber temperature to suppress the generation of tar during the carbon coating process.

[0057] Step 209 , determining whether the real-time conversion rate is equal to the second preset conversion rate, if so, executing step 210 ; if not, returning to executing step 201 .

[0058] Step 210: maintain the third flow rate unchanged and reduce the first flow rate to suppress the generation of tar during the carbon coating process.
