Description

Technical Field

[0001] This application relates to the field of blast furnace smelting, specifically to a device and method for testing the performance of coke under hydrogen-rich conditions. Background Technology

[0002] Blast furnace ironmaking is the main process in modern steel production. Coke, as an indispensable reducing agent, heat source, and supporting framework for the furnace charge, directly affects the economy and stability of blast furnace operation. Current testing methods for coke reactivity index (CRI) and post-reaction strength (CSR) are determined using standardized experimental equipment under a pure CO2 atmosphere. However, with the rapid development of hydrogen-rich low-carbon ironmaking technology, the introduction of a hydrogen-rich atmosphere into the blast furnace alters the composition of the gas and the reaction conditions, particularly the increased H2O content, which places new demands on the reactivity and post-reaction strength of coke.

[0003] Currently, traditional coke performance testing devices and methods cannot fully simulate real-world conditions under hydrogen-rich environments, leading to discrepancies between test results and actual application scenarios. Therefore, developing a coke performance testing device and method suitable for hydrogen-rich conditions is of great significance for promoting the development of low-carbon ironmaking technology.

[0004] This section is intended to provide background or context for the embodiments of the invention set forth in the claims. The description herein is not an admission that it is prior art simply because it is included in this section. Summary of the Invention

[0006] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0007] In a first aspect, this application provides a coke performance testing device under hydrogen-rich conditions, comprising: a reactor, a heating furnace covering the reactor, and a steam generator connected to the reactor;

[0008] The steam generating device includes a water tank, a heating device located at the bottom of the water tank, an air inlet, a water inlet, and an air outlet located at the top of the water tank.

[0009] The heating device is used to heat the water in the water tank to generate water vapor; carbon dioxide gas enters the water tank from the air inlet to preheat and generate preheated reaction gas; the water vapor and the preheated reaction gas are transported to the reactor through the air outlet; the heating furnace is used to heat the reactor so that the coke sample to be tested can complete the performance test in the reactor.

[0010] Furthermore, an air inlet is provided at the bottom of the reactor; the air outlet is connected to the air inlet; and the pipe between the air outlet and the air inlet is wrapped with an insulation layer.

[0011] Furthermore, the steam generating device also includes a thermometer for real-time monitoring of the water tank temperature; and a water level monitor for indicating the water level in the water tank.

[0012] Furthermore, the reactor forms a closed structure through the upper and lower flanges; the coke sample to be tested is loaded inside the reactor through a crucible; the bottom of the crucible has a porous mesh structure to allow the water vapor and the preheated reaction gas to enter the crucible.

[0013] Furthermore, the reactor also includes a thermocouple; the thermocouple is inserted from the upper flange into the crucible to monitor the temperature of the coke sample to be tested.

[0014] Furthermore, the reactor also includes a gas outlet located at the top of the reactor for discharging the gases produced in the reaction.

[0019] The reactor is heated using a heating furnace; when the temperature reaches the first preset temperature, nitrogen gas is introduced into the reactor through the gas inlet; when the temperature reaches the second preset temperature, the nitrogen gas supply is cut off.

[0020] Carbon dioxide is preheated by a steam generator and then introduced into the reactor through the inlet along with the steam, so that the coke reacts with the gas inside the reactor.

[0021] When the reaction time reaches the preset time, stop heating the reactor and introduce nitrogen gas into the reactor from the inlet according to the preset flow rate;

[0022] After the reactor cools down, the coke sample is taken out, the mass of the coke after the reaction is weighed, and the coke reactivity data is determined using the pre-constructed coke reactivity analysis model.

[0023] After the coke is fully loaded into the drum and rotated, it is removed, sieved with a round hole sieve, the mass of the material on the sieve is weighed, and the strength data of the coke after reaction is determined using a pre-constructed coke post-reaction strength analysis model.

[0024] Furthermore, the coke reactivity analysis model is CRI = (m0 - m1) / m0 × 100%; where m0 is the mass of the coke sample after drying and removing moisture in the oven; m1 is the mass of the coke after the reaction; and CRI is the coke reactivity data.

Detailed Implementation

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] In one embodiment, see Figure 1 In order to more accurately analyze the effects of water vapor and carbon dioxide on the reactivity and post-reaction strength of coke, and to provide important data support for the development of hydrogen-rich blast furnace ironmaking process, this application provides a coke performance testing device under hydrogen-rich conditions, including: reactor 13, heating furnace 4 covering reactor 13 and water vapor generator 17 connected to reactor 13.

[0033] The steam generating device 17 includes a water tank 20, a heating device 21 disposed at the bottom of the water tank 20, an air inlet 16 disposed at the top of the water tank 20, a water inlet 15 disposed at the top of the water tank 20, and an air outlet 14.

[0034] The heating device 21 is used to heat the water in the water tank 20 to generate water vapor; carbon dioxide gas enters the water tank 20 from the air inlet 16 to preheat and generate preheated reaction gas; the water vapor and the preheated reaction gas are transported to the reactor 13 through the air outlet 14; the heating furnace 4 is used to heat the reactor 13 so that the coke sample 7 to be tested can complete the performance test in the reactor 13.

[0035] Specifically, the steam generating device 17 further includes a thermometer 18 for real-time monitoring of the temperature of the water tank 20; and a water level monitor 19 for indicating the water level in the water tank 20.

[0036] Understandably, in response to the shortcomings of existing technical solutions, this application proposes a testing device for simulating the performance of coke under a hydrogen-rich atmosphere in a blast furnace. By introducing a steam generator 17, it achieves precise control of the H2O ratio in the reaction atmosphere, thereby more accurately evaluating the CRI and CSR of coke under hydrogen-rich conditions; where CRI is the coke reactivity data; and CSR is the coke strength data after the reaction.

[0037] Specifically, in conducting H2O vaporization experiments, a steam generator is required, and the steam flow rate is indirectly adjusted through a temperature control system. To verify the generated steam flow rate, the silica gel hygroscopic method can be used, and the steam flow rate can be accurately calculated by measuring the mass change of the silica gel before and after absorption. Therefore, in H2O vaporization experiments, the corresponding temperature (T) can be calculated and set according to the required steam flow rate (Q) to achieve precise flow control. For example, the temperature (T) and flow rate (Q) can be linearly fitted; the relationship between temperature (T) and flow rate (Q) can be determined through data fitting: Q = aT + b; where a and b are the coefficients to be fitted.

[0038] Steam generator 17: A water tank 20 is located at the top of the device and is used to store distilled water or pure water to ensure water supply quality. A heating device 21 is located at the bottom of the water tank 20 and generates steam through electric heating. A thermometer 18 monitors the temperature of the water tank 20 in real time, and a water level monitor 19 indicates the water level in the water tank 20 to prevent test interruption due to excessive or insufficient water. The top of the steam generator 17 is equipped with an air inlet 16, a water inlet 15, and an air outlet 14. The gas required in the reactor 13 enters the steam generator 17 through the air inlet 16 for preheating. The generated steam and preheated reaction gas are introduced into the reactor through the air outlet 14 via a pipe. The pipe between the air outlet 14 and the reactor air inlet 12 is surrounded by an insulation layer to prevent condensation during steam transmission.

[0039] Specifically, a heating element 5 is provided inside the heating furnace 4; the heating element 5 is uniformly arranged in a ring along the inner wall of the heating furnace 4 to form an axisymmetric structure.

[0040] Understandably, the heating furnace 4 encloses the reactor 13 to provide a high-temperature environment, with a maximum operating temperature of up to 1300℃, ensuring the conditions required for testing. The heating elements 5 are arranged uniformly in a ring along the inner wall of the heating furnace 4, forming an axisymmetric heating structure to ensure uniform temperature distribution within the reactor 13 and avoid localized overheating or excessive temperature gradients. The heating furnace 4 is connected to thermocouples 8 for real-time furnace temperature monitoring.

[0041] Specifically, the bottom of the reactor 13 is provided with an air inlet 12; the air outlet 14 is connected to the air inlet 12; and the pipe between the air outlet 14 and the air inlet 12 is wrapped with a heat insulation layer.

[0042] Specifically, the reactor 13 forms a closed structure through the upper flange 3 and the lower flange 11; the coke sample 7 to be tested is loaded inside the reactor 13 through the crucible 6; the bottom of the crucible 6 has a porous mesh structure to allow the water vapor and the preheated reaction gas to enter the crucible 6.

[0043] Specifically, the reactor 13 further includes a thermocouple 1; the thermocouple 1 is inserted from the upper flange 3 into the crucible 6 to monitor the temperature of the coke sample 7 to be tested.

[0044] Specifically, the reactor 13 also includes a gas outlet 2 located at the top of the reactor 13 for discharging the gas generated during the reaction.

[0045] Specifically, the reactor 13 is also provided with a preheating baffle 10 and a corundum bead 9 for gas preheating; wherein the corundum bead 9 is placed on the preheating baffle 10 to make the water vapor and preheated reaction gas in the reactor 13 evenly distributed.

[0046] As can be understood, reactor 13 forms a closed structure through upper flange 3 and lower flange 11. Inside, a crucible 6 holds the coke sample 7 to be tested. The bottom of the crucible is a porous mesh to allow the reaction gas to pass through. A thermocouple 1 is inserted from the top of the reactor to monitor the temperature of the coke sample. Gas-preheated corundum beads 9 are placed on a preheating baffle 10 to ensure uniform gas distribution. The outlet 2 is located at the top of the reactor to discharge the gases produced in the reaction. The inlet 12 is located at the bottom of the reactor and is connected to the gas supply system for inputting CO2, N2, and water vapor.

[0047] In other embodiments, water vapor can be generated using other devices such as ultrasonic atomizers to replace the water vapor generator 17 of this application; in addition, the water vapor flow rate can be precisely adjusted using a gas mass flow meter.

[0048] As described above, the coke performance testing device under hydrogen-rich conditions provided in this application precisely generates steam and adjusts the steam flow rate through the coordinated control of heating equipment, thermometers, and water level monitors, simulating the complex atmosphere under different hydrogen-rich conditions in the blast furnace. By optimizing the reaction atmosphere and device structure design, this application can more accurately analyze the effects of steam and carbon dioxide on the reactivity and post-reaction strength of coke, providing important data support for the development of hydrogen-rich blast furnace ironmaking technology.

[0049] In one embodiment, see Figure 2 This application also provides a method for testing the performance of coke under hydrogen-rich conditions, applied to the aforementioned coke performance testing apparatus under hydrogen-rich conditions, comprising:

[0050] S101: Place the weighed coke sample 7 to be tested into the crucible, seal the upper flange 3 and the lower flange 11, and insert the thermocouple 1 into the surface of the coke sample 7 to be tested.

[0051] S102: The reactor 13 is heated by the heating furnace 4; when the temperature reaches the first preset temperature, nitrogen gas is introduced into the reactor 13 through the gas inlet 12; when the temperature reaches the second preset temperature, the nitrogen gas is cut off.

[0052] S103: After carbon dioxide is preheated by the steam generator 17, it is introduced into the reactor 13 through the air inlet 12 along with the steam, so that the coke reacts with the gas in the reactor.

[0053] S104: When the reaction time reaches the preset time, stop heating the reactor 13 and introduce nitrogen gas into the reactor 13 from the inlet 12 according to the preset flow rate;

[0054] S105: After the reactor 13 has cooled down, take out the coke sample 7 and weigh the mass of the coke after the reaction.

[0055] S106: After all the reacted coke is loaded into the drum and rotated, the coke is removed, sieved with a round hole sieve, and the mass of the material on the sieve is weighed.

[0056] Among them, the coke reactivity data is determined by the data processor based on the mass of coke sample 7 after drying and removing moisture in the oven, the mass of coke after reaction, and the pre-constructed coke reactivity analysis model.

[0057] The data processor determines the post-reaction strength data of the coke based on the mass of the coke after the reaction, the mass of the material on the sieve, and a pre-constructed post-reaction strength analysis model of the coke.

[0058] The coke reactivity analysis model is CRI = (m0 - m1) / m0 × 100%; where m0 is the mass of coke sample 7 after drying and removing moisture in the oven; m1 is the mass of coke after reaction; and CRI is the coke reactivity. The coke post-reaction strength analysis model is CSR = m2 / m1 × 100%; where m2 is the mass of the material on the sieve; and CSR is the coke post-reaction strength.

[0059] It is understood that the method for determining coke performance under hydrogen-rich conditions provided in this application includes the following steps:

[0060] 1) Select suitable coke particles and prepare them into approximately spherical shapes with a particle size of 23mm to 25mm as samples for determining coke properties (also known as coke test samples). After drying the coke test samples in an oven for 2 hours to remove moisture, weigh 200g ± 0.5g of coke and record it as m0.

[0061] 2) Place the weighed coke sample to be tested into the crucible 6, seal the upper flange 3 and the lower flange 11, and insert the thermocouple 1) onto the surface of the coke sample to be tested.

[0062] 3) Connect the inlet and outlet of reactor 13 and steam generator 17 to the gas supply system (the system that provides the gas required for the test) and the exhaust system (the system that discharges the gas generated for the test) respectively, check the gas path and ensure that it is tight.

[0063] 4) Start the heating furnace 4 to heat the reactor 13 at a rate of 8-12℃ / min. When the temperature reaches 400℃, keep nitrogen gas flowing directly into the reactor 13 at a rate of 0.8±0.1L / min through the inlet 12 to prevent coke burn-off.

[0064] 5) When the temperature reaches 1100℃, stabilize for 10 minutes, cut off the nitrogen gas, and introduce (H2O+CO2) with a total flow rate of 5±0.1L / min. After the carbon dioxide is preheated by the steam generator 17, it enters the reactor 13 with the steam through the inlet 12. The gas ratio (H2O / CO2) is set by the laboratory.

[0065] 6) Maintain a constant atmosphere and temperature, and let the coke and gas react in reactor 13 for 2 hours.

[0066] 7) Stop heating, close the reaction gas channel, and switch to nitrogen gas at a flow rate of 2±0.1 L / min.

[0067] 8) After the device has cooled down, take out the coke sample, weigh the mass of the coke after the reaction, and record the mass as m1. The coke reactivity (CRI) is calculated according to formula (1):

[0068] CRI=(m0-m1) / m0×100% (1)

[0069] 9) After the reaction, all the coke is loaded into a type I rotary drum and rotated at 20 r / min for 30 min. Then, the coke is removed, sieved through a Ф10 mm round-hole sieve, and the mass of the material remaining on the sieve is weighed and recorded as m2. The coke strength (CSR) after the reaction is calculated according to formula (2):

[0070] CSR=m2 / m1×100% (2)

[0071] The reactivity and post-reaction strength of the coke were tested three times, and the average value of the results was taken. Table 1 shows the test results of the reactivity and post-reaction strength of the coke used in this experiment under different atmospheric conditions. The results show that the higher the proportion of H2O in the reaction, the stronger the reactivity of the coke and the lower the post-reaction strength.
