Description

Technical Field

[0001] The invention relates to the technical field of reduction smelting, and in particular to an oxygen-enriched side-blowing smelting furnace and a smelting process. Background Art

[0002] Oxygen-enriched side-blowing reduction smelting technology is an emulsion pyrometallurgical process. The process mechanism is that solid charge is added to a molten pool of molten slag at a certain temperature (the specific temperature is determined by the raw material composition) and stirred. The charge particles or aggregates are wetted by the slag and heated by the temperature difference between the slag and the charge particles. Reducing gas is blown into the slag melt to react with the slag at the phase interface, and the composition of the liquid phase and the gas phase is changed accordingly until a chemical equilibrium is established between the two phases. Because the area of ​​the phase interface is large and the gas gives the molten pool a high stirring energy, the heat and mass transfer processes in the furnace are accelerated, the composition of each phase tends to be balanced, and the phase separation process is greatly accelerated.

[0003] After searching, the Chinese patent number CN109539785A discloses a side-blown oxygen-enriched submerged combustion smelting furnace, which belongs to the technical field of smelting equipment, including a first furnace body, a second furnace body sleeved on the first furnace body, a gas supply bottle and a plurality of spray guns. A uniform and sealed gap space is formed between the outer wall of the first furnace body and the inner wall of the second furnace body. A feeding channel is provided on the top of the first furnace body, a chimney is provided on the top of the first furnace body, and a first flue connected to the chimney is provided on one side wall of the chimney; an annular baffle is provided above the spray gun in the gap space to ensure the temperature in the furnace is stable and avoid furnace blockage, and it can also reduce the consumption of gas fuel and save energy.

[0004] After searching, the Chinese patent number CN111102847A discloses a low-emission oxygen-enriched side-blown smelting furnace, including a main body and a dust removal device. The main body is provided with a smoke exhaust port. The dust removal device includes a dust removal tank, a conveying pipe and a stirring member. The dust removal tank is provided with a dust removal chamber, and an exhaust port is provided on the top. The conveying pipe has an input end and an output end, the input end is connected to the smoke exhaust port, and the output end is inserted into the dust removal chamber.

The windward plate is vertically arranged, and its lower end is connected to the upper end of the positioning member. The stirring blade is horizontally arranged and fixed at the junction of the positioning member and the windward plate, which can better achieve the dust removal effect.

[0055] A smelting process of an oxygen-enriched side-blown smelting furnace, characterized in that it comprises the following steps:

[0056] Step S1, feeding and guiding, through the feed port 102, the material passes through the guiding mechanism 2 into the inner cavity of the furnace body 101, so that it is evenly distributed;

[0057] Step S2, vibration and adjustment, through the cooperation of the vibration component 4 and the adjustment component 5, the material can be vibrated and the transportation of the material can be accelerated;

[0058] Step S3, side blowing smelting, through the cooperation of the furnace chamber 106 and the ventilation pipe layer 109, the smelting rate of the material is accelerated

[0059] The working principle of the embodiment of the present invention is: oxygen-enriched or pure oxygen air is sent into the molten pool from the tuyere on the side wall of the furnace body 101 at a gauge pressure of about 100 kPa, forming a strong bubbling and stirring effect. In this process, the solid charge is added to the molten slag at a certain temperature, and is heated and melted by the temperature difference between the slag and the charge particles. The fusible components form metal phase droplets in the slag, while the flux, high melting point components and coal, etc. are strongly stirred or melted in the slag, burned or reacted with oxygen in the slag to achieve the transformation and separation of the components. At the same time, the ventilation pipe 110 in the ventilation pipe layer 109 provides the necessary oxygen supply for the smelting process and accelerates the smelting reaction. Through the synergistic effect of the furnace chamber 106 and the ventilation pipe layer 109, the smelting rate is significantly improved, and the dust particles in the flue gas are effectively reduced, which meets the environmental protection requirements. During the smelting process, the generated flue gas is discharged through the ascending flue 103 at the top of the furnace body 101. Multiple groups of ascending flues 103 distributed in a linear array ensure smooth exhaust of smoke and avoid accumulation of smoke in the furnace body 101, thereby ensuring cleanliness and safety of the smelting environment.

[0060] Working principle: The frame mechanism 1 constitutes the main body of the smelting furnace, including the furnace body 101, the feed port 102, the ascending flue 103 and the conveyor belt 104 key components. The furnace body 101 is the core area of ​​the smelting reaction, and the feed port 102 opened on the top is responsible for receiving and introducing the materials to be smelted. The ascending flue 103 is distributed in multiple groups of linear arrays, which effectively guides the flue gas generated during the smelting process for subsequent treatment to ensure that environmental protection standards are met. The material entering the furnace body 101 from the feed port 102 will pass through the guide mechanism 2. At this time, the guide motor 201 starts, driving the screw rod 203 to rotate. During the rotation of the screw rod 203, it will drive the moving block 204 and the feeder 205 to move, so that the material can enter the feed port 102 evenly, avoiding accumulation at a certain position of the feed port 102. The feeder 205 is a funnel-shaped structure that is wide at the top and narrow at the bottom, which helps the material to enter the inner cavity of the furnace body 101 stably and evenly. This design not only improves the uniformity of material distribution, but also reduces the reduction in smelting efficiency and increase in energy consumption caused by material accumulation.

[0061] The working mechanism is installed in the inner cavity of the furnace body 101 to prevent material blockage and ensure the continuity and stability of the smelting process. The mechanism consists of a screening component 3, a vibration component 4 and an adjustment component 5. The material falling into the furnace body 101 first passes through the screening component 3. The transport frame 303 vibrates under the drive of the vibration motor 304, and the combination of the damper 302 and the spring 305 provides a buffering and stabilizing effect to prevent excessive impact during the vibration process. The material is vibrated in the transport frame 303 and is initially separated through the filter hole 601. Larger particles are blocked in the transport frame 303, while smaller particles fall into the vibration component 4 below through the filter hole 601. The setting of the baffle plate 602 allows the operator to adjust the opening size of the filter hole 601 as needed to further control the separation effect of the material.

[0062] The vibration component 4 starts to work under the drive of the driving motor 401. The driving shaft 402 drives the working cam 403 to rotate. Due to the cooperation between the cam groove 406 opened at the bottom of the transfer frame 405 and the working cam 403, the transfer frame 405 generates reciprocating vibration in the horizontal direction. This vibration promotes the mixing and transportation of materials in the transfer frame 405, so that it can enter the next stage of the smelting process more quickly. The adjustment component 5 realizes the adjustment of the height of the lifting plate 505 through the threaded connection between the threaded rod 503 and the connecting plate 501. When the crank 504 rotates, the threaded rod 503 drives the lifting plate 505 to move up and down, thereby changing the vibration amplitude of the vibration component 4, and the telescopic rod 506 provides additional stability and support. This design allows the operator to flexibly adjust the vibration amplitude of the vibration component 4 according to the properties of the material and the smelting requirements, so as to achieve the subsequent best smelting effect.

[0063] During the smelting process, oxygen-enriched or pure oxygen air is fed into the molten pool from the tuyere on the side wall of the furnace body 101 at a gauge pressure of about 100 kPa, forming a strong bubbling and stirring effect. In this process, solid charge is added to the molten slag at a certain temperature, and is heated and melted by the temperature difference between the slag and the charge particles. The fusible components form metal phase droplets in the slag, while the flux, high melting point components and coal are transformed and separated by strong stirring or melting in the slag, burning or reacting with the oxygen in the slag. At the same time, the ventilation pipe 110 in the ventilation pipe layer 109 provides the necessary oxygen supply for the smelting process and accelerates the smelting reaction. Through the synergistic effect of the furnace chamber 106 and the ventilation pipe layer 109, the smelting rate is significantly improved, and the dust particles in the flue gas are effectively reduced, which meets environmental protection requirements. During the smelting process, the generated flue gas is discharged through the ascending flue 103 at the top of the furnace body 101. Multiple groups of ascending flues 103 distributed in a linear array ensure smooth exhaust of smoke and avoid accumulation of smoke in the furnace body 101, thereby ensuring cleanliness and safety of the smelting environment.
