Technical Field
[0001] The invention relates to the technical field of steelmaking, in particular to an oxygen supply device for a dry dust removal converter. Background Art
[0002] In steel production, iron products need to be smelted and melted into liquid. During the smelting process of superior iron products, a large amount of high-temperature flue gas will be generated. These flue gases contain more impurities and cannot be directly discharged into the atmosphere. Therefore, there will be a flue gas treatment process in the steelmaking process to ensure that the discharged flue gas does not pollute the atmosphere.
[0003] At present, the method for treating high-temperature flue gas is to transfer the smelted molten iron to a dry dust removal converter, and treat the high-temperature flue gas through the equipment.

Therefore, after the molten iron enters the converter, oxygen needs to be input into the converter. At present, most of the oxygen supply guns are positioned. As the amount of molten iron in the converter continues to increase, the molten iron level will rise. In order to avoid damage to the oxygen supply gun, the amount of molten iron entering will be controlled.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0021] In a preferred embodiment, a ceramic pipe 4 is fixedly installed on the outside of the smelting furnace 1, and a vacuum iron pump 5 is installed on the ceramic pipe 4 for sucking and transporting molten iron. The two ends of the ceramic pipe 4 are respectively connected to the inside of the smelting furnace 1 and the furnace body 2. An air pressure detector 6 and a temperature detector 7 are installed on the outside of the smelting furnace 1. This device places the raw materials inside the smelting furnace 1 for calcining to turn them into molten iron. In order to ensure safe production, an air pressure detector 6 and a temperature detector 7 are installed on the smelting furnace 1 to avoid danger caused by excessive air pressure and meet the requirements of use.
[0022] In a preferred embodiment, a porous plate 8 is fixedly installed inside the furnace body 2, a circular tube 9 is fixedly installed on the furnace body 2, one end of the circular tube 9 is installed inside the furnace body 2, and an air inlet 10 is opened on the outer surface of the circular tube 9 arranged inside the furnace body 2. In order to facilitate the collection and treatment of flue gas, the device installs a porous plate 8 inside the furnace body 2. When the flue gas passes through the porous plate 8, some large particles can be filtered out to avoid subsequent blockage of the circular tube 9, thereby ensuring the treatment effect of the flue gas, and the flue gas will float at the upper end of the furnace body 2 to facilitate the collection and treatment of the flue gas.
[0023] In a preferred embodiment, a carbon monoxide treatment mechanism 11 is installed on the circular tube 9, and the carbon monoxide treatment mechanism 11 includes a support frame 111, a medicine bag 112 and a baffle 113. The support frame 111 is fixedly installed at the upper end of the circular tube 9, and the medicine bag 112 is fixedly installed on the support frame 111. A liquid outlet pipe 12 is installed at the bottom of the medicine bag 112, and a connecting rod 13 is arranged inside the liquid outlet pipe 12.

A partition 15 is fixedly installed at the position outside the bottom end of the circular tube 9, and the partition 15 is fixedly connected to the porous plate 8.
[0024] In actual use, as the air pressure inside the circular tube 9 continues to increase, the circular plate 14 installed at the bottom of the medicine bag 112 will be pushed upward, so that the partition 15 is close to the liquid outlet of the medicine bag 112, thereby increasing the liquid outlet speed of the reactant and allowing it to fully react with carbon monoxide. The device also has a carbon monoxide concentration detector 301 installed on the furnace body 2. The carbon monoxide concentration detector 301 is used to detect the carbon monoxide concentration inside the furnace body 2. When the carbon monoxide concentration value is less than the set value, oxygen can be transported to the inside of the furnace body 2 to ensure that oxygen is transported under safe conditions.
[0025] In order to prevent the nozzle 321 from being damaged by being inserted into the molten iron, a through hole 16 is opened on the outer side of the mounting frame 31, and a sliding groove 17 is opened on the inner wall of the through hole 16. A moving block 18 is arranged inside the sliding groove 17, and the outer side of the moving block 18 is fixedly connected to the connecting plate 311. A limit plate 19 is fixedly installed at the position on the inner side of the mounting frame 31, and the inner side of the limit plate 19 is stably connected to a pressure sensor 20, which is electrically connected to a PLC controller 21. A connecting pipe 22 is fixedly installed outside the airbag 33, and an electronic control valve is arranged on the connecting pipe 22, which is electrically connected to the PLC controller 21. One end of the connecting pipe 22 is connected to the interior of the circular tube 9, and an airflow disturbance mechanism 23 is installed inside the circular tube 9, and the airflow disturbance mechanism 23 includes a rotating wheel 231 and a rotating shaft 232.
[0026] In actual use, the molten iron inside the smelting furnace 1 is transported to the inside of the furnace body 2. The amount of molten iron inside the furnace body 2 continues to increase, which will increase the air pressure inside the furnace body 2, and the gas inside the furnace body 2 will enter the airbag 33. The increase in gas inside the airbag 33 will cause the airbag 33 to expand, thereby pushing the connecting plate 311 upward, and then driving the nozzle 321 to move upward, thereby preventing the nozzle 321 from extending into the molten iron and causing damage.
[0027] And a rotating shaft 232 is rotatably connected at the bottom of the circular tube 9, a rotating wheel 231 is fixedly installed on the upper end of the rotating shaft 232, the position of the rotating wheel 231 corresponds to the position of the connecting pipe 22, and a conical wheel 24 is fixedly installed at the bottom of the rotating shaft 232, the conical wheel 24 is rotatably arranged inside the circular tube 9, when the air pressure inside the inflatable bag 33 becomes large, it is necessary to exhaust in time, the gas inside the inflatable bag 33 will be transported to the inside of the circular tube 9, and the rotating wheel 231 will rotate under the blowing of the gas, so as to stir the gas inside the circular tube 9, accelerate the gas flow, and thus relieve the air pressure inside the circular tube 9, and at the same time, the rotation of the rotating shaft 232 will drive the conical wheel 24 to rotate, which can grind the solid material produced by the reaction, reduce the volume of the solid material, avoid material jamming, and facilitate material discharge.
[0028] The volume of the solid material after grinding will become smaller. To facilitate unloading, a slag discharge pipe 25 is fixedly installed on the outside of the furnace body 2. One end of the slag discharge pipe 25 is connected to the bottom of the circular tube 9. A control valve is installed on the slag discharge pipe 25 to discharge the reaction solid from the inside of the circular tube 9 through the slag discharge pipe 25.
[0029] The treated gas inside the circular tube 9 will continue to be transported, and a gas delivery pipe 26 is fixedly connected to the outside of the circular tube 9. One end of the gas delivery pipe 26 is fixedly connected to the evaporative refrigerator 27. An exhaust pipe 28 is fixedly installed at the gas outlet end of the evaporative refrigerator 27. One end of the exhaust pipe 28 is connected to the electrostatic precipitator 29, and a gas storage tank 30 is installed outside the electrostatic precipitator 29. The gas storage tank 30 is connected to the electrostatic precipitator 29 through another circular tube 9, so as to treat the flue gas for easy use.
[0030] Specifically, the working process or working principle of the oxygen supply device of the dry dust removal converter is as follows: the current method of treating high-temperature flue gas is to transfer the smelted molten iron to the dry dust removal converter, and treat the high-temperature flue gas through the equipment. The coal gas can also be collected and used through the equipment, which is suitable for production use for resource recycling. However, the liquid entering the converter is only molten iron, not molten steel. Therefore, after the molten iron enters the converter, oxygen needs to be input into the converter, and the carbon content in the molten iron is reduced by the participation of oxygen in the reaction, thereby converting it into molten steel. Since there will be a large amount of carbon monoxide in the high-temperature flue gas, when the carbon monoxide concentration is high and oxygen is input at this time, it is very easy to cause the risk of explosion, which will also cause harm to the staff, so this device is designed to solve this problem.
[0031] The device can reduce the concentration of carbon monoxide in the high-temperature flue gas, ensure the safe input of oxygen, and in the process of inputting oxygen, the nozzle 321 will be controlled to move upward as the amount of molten iron in the furnace body 2 increases, so as to prevent the nozzle 321 from extending into the molten iron and causing damage to the nozzle 321. The specific operation is to connect an external power supply, put some iron products into the inside of the smelting furnace 1, process the iron products into molten iron through the smelting furnace 1, and suck the molten iron into the inside of the furnace body 2 through the vacuum suction pump 5. Since the molten iron will carry a large amount of flue gas, the high-temperature flue gas generated after the molten iron enters the furnace body 2 will rise above the porous plate 8 and enter the inside of the air inlet 10 from the upper end of the furnace body 2, so that a large amount of flue gas will enter the inside of the circular tube 9, and at the same time, titanium tetroxide is added to the inside of the liquid medicine capsule 112, and the reactant passes through the liquid medicine capsule 112 and enters the inside of the circular tube 9 and reacts with the carbon monoxide in the mixed gas, as shown in the following reaction formula:
[0032] It can be seen from the reaction formula that solid titanium will be generated and fall to the bottom of the circular tube 9. As the air pressure inside the circular tube 9 continues to increase, the circular plate 14 installed at the bottom of the medicine bag 112 will be pushed upward, so that the partition 15 is close to the liquid outlet of the medicine bag 112, thereby increasing the liquid outlet speed of the reactant and allowing it to fully react with carbon monoxide. The device also has a carbon monoxide concentration detector 301 installed on the furnace body 2. The carbon monoxide concentration detector 301 detects the carbon monoxide concentration inside the furnace body 2. When the carbon monoxide concentration value is less than the set value, oxygen can be transported to the furnace body 2 to ensure that oxygen is transported under safe conditions. Oxygen is output through the oxygen tank 32, and the jet is sprayed to the surface of the molten iron through the jet head 321. The outer surface of the molten iron will be blown by strong blowing, causing the surface of the molten iron to fluctuate, so that oxygen reacts with the carbon substance in the molten iron to reduce the carbon content in the molten iron to meet the use.
[0033] As the amount of molten iron inside the furnace body 2 continues to increase, the air pressure inside the furnace body 2 will increase, and the gas entering the air bag 33 will continue to increase and expand. The expansion of the air bag 33 will push the connecting plate 311 to move upward. When the connecting plate 311 moves upward, it will also drive the nozzle 321 to move upward, so as to adjust the position of the nozzle 321, so that the nozzle 321 can spray normally while avoiding damage, which is convenient for use.
[0034] As the connecting plate 311 continues to rise, it will squeeze the pressure sensor 20. When the pressure sensor 20 detects the existence of pressure, the vacuum suction pump 5 will be controlled to stop working through the PLC controller 21, and the electronic control valve on the connecting pipe 22 will be controlled to open, so that the gas inside the air bag 33 will be passed into the inside of the circular tube 9 for processing inside the circular tube 9. At this time, the air pressure inside the air bag 33 will drop, and drive the nozzle 321 to slowly descend, and at this time the molten iron inside the furnace body 2 will be discharged, and the molten iron inside the smelting furnace 1 will repeat the above steps to add it into the furnace body 2, and oxygen will be passed into the furnace body 2 again.
[0035] After being processed inside the circular tube 9, the gas will move to the inside of the evaporative refrigerator 27 through the gas pipe 26. The evaporative refrigerator 27 can use a refrigerator of the Leibao series mfc18000500w 160l water tank to meet production needs. The flue gas is cooled by the evaporative refrigerator 27, and the cooled flue gas is transported to the inside of the electrostatic precipitator 29. The flue gas is removed by the electrostatic precipitator 29, and after being processed, the flue gas can be discharged into the atmosphere, effectively avoiding pollution to the environment.
[0036] The solid titanium inside the circular tube 9 falls to the bottom of the circular tube 9. When air is ventilated into the interior of the circular tube 9 through the inflatable bag 33, the rotating wheel 231 is blown to rotate, and the rotating shaft 232 is driven to rotate. When the rotating shaft 232 rotates, the conical wheel 24 is also driven to rotate. The solid titanium falls to the position of the conical wheel 24. In order to avoid the jamming of the solid material when unloading, the solid titanium can also be ground while the conical wheel 24 rotates to reduce its volume, thereby facilitating the discharge of the solid material from the inside of the slag discharge pipe 25 to meet the use requirements.
[0037] In order to grind solid titanium, the device uses diamond material for the conical wheel 24. The diamond grinds the titanium to reduce its volume and avoid material jamming.
