Description

Technical Field

[0001] The present invention relates to the technical field of smelting furnaces, and particularly to an environment-friendly metal smelting furnace with heat energy recovery and utilization. Background Art

[0002] Metal materials are a precious resource and are widely used in fields such as the construction industry, transportation industry, and power industry. During long-term use, metal materials will be oxidized and thus corroded, and need to be recycled and smelted. A smelting furnace is required for their recycling and smelting.

[0003] An environment-friendly precious metal beneficiation agent preparation device with the application number CN202022182714.2 includes a support plate, a smelting furnace, a spray adsorption tower, a cooling tank, and a crushing tank; the surface of the right part of the support plate is hinged to both sides of the upper part of the smelting furnace through support rods; the smelting furnace is connected to the air inlet hole of the spray adsorption tower through an exhaust pipe; a cooling tank is installed in the middle of the support plate, and the cooling tank is placed on the side close to the smelting furnace; the left part of the surface of the support plate is connected to both sides of the upper part of the crushing tank through a support frame. The utility model passes the polluted gas generated in the smelting furnace into the spray adsorption tower, solves the problem of direct emission of the polluted gas generated in the production process of the existing environment-friendly precious metal beneficiation agent, and realizes the development of precious metal production technology towards the direction of no pollution or little pollution.

[0004] This device treats the polluted gas generated by smelting through a spray layer and an adsorption layer, thereby preventing the polluted gas from being discharged outdoors and polluting the air. However, it can only adsorb and degrade the dust inside the polluted gas. There are a large amount of sulfur elements in the polluted gas, and the discharge of these sulfur elements and other polluted gases outdoors and being absorbed by the human body will cause certain harm to the human body.

[0005] A metal recycling smelting device for resource recovery with the application number CN202210779662.8. Technical problem: The high-temperature smelting waste gas carries dust and sulfides. General dust removal methods are difficult to remove the dust completely, and the subsequent treatment of the dust is troublesome, and the removal of sulfides in the waste gas is not thorough. Technical solution: A metal recycling smelting device for resource recovery includes a dust removal system and a desulfurization system, etc.; the upper part of the dust removal system is connected to a desulfurization system for desulfurizing the smelting waste gas. The present invention throws the waste gas containing dust against the inner wall of the clean gas tower, and at the same time recovers the heat. The recovered heat presses water into the clean gas tower to spray the smelting waste gas, and the dust settles. And the smelting waste gas is pressed into the eluent in the desulfurization barrel to fully absorb the sulfides in the waste gas, avoiding directly discharging the sulfides into the air and causing environmental pollution.

[0006] This device utilizes the waste heat from smelting to recover sulfur compounds through extraction. However, the utilization of waste heat from smelting is limited and its functions are single. According to investigations, the total waste heat resources in various industries account for about 17% to 67% of their total fuel consumption, and the recoverable waste heat resources are approximately 60% of the total waste heat resources. Merely using waste heat for sulfur compound extraction will cause waste of heat, thereby increasing the cost of smelting.

[0007] Therefore, we propose an environmentally friendly metal smelting furnace with heat energy recovery and utilization to solve the problems raised above. Summary of the Invention

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-8 , the present invention provides a technical solution: an environmentally friendly metal smelting furnace with heat energy recovery and utilization, including a smelting furnace 1, a first connecting pipe 2, a connector 3, a bag filter 4, a limit hole 5, a telescopic spring 6, a limit rod 7, a tee pipe 8, a second connecting pipe 9, a waste heat boiler 10, a desulfurization reactor 11, a sulfur storage tank 12, a smoke outlet 13, a steam turbine 14, a generator 15, a support leg 16, a discharge port 17, an output motor 18, a stirrer 19, a scraper 20, a first transmission shaft 23, a first transmission belt 24, a first central shaft 25, a first bevel gear 26, a second bevel gear 27, a second central shaft 28, a second transmission belt 29, a rotating disk 30, a rotating rod 31, a condenser 33, a deaerator 34, a third connecting pipe 35 and a sealing plate 36.

[0026] The outside of the smelting furnace 1 is fixedly connected with a first connecting pipe 2, and a connector 3 is fixedly installed on the outside of the first connecting pipe 2. The inside of the connector 3 is connected with a bag filter 4, and a limit hole 5 is opened inside the bag filter 4. A telescopic spring 6 is fixedly installed on the outside of the connector 3, and the tail end of the telescopic spring 6 is fixedly connected with a limit rod 7, and the limit rod 7 penetrates through the inside of the connector 3. The tail end of the first connecting pipe 2 is fixedly connected with a tee pipe 8, and a second connecting pipe 9 is fixedly connected to the outside of the tee pipe 8. The tail end of the second connecting pipe 9 is fixedly connected with a waste heat boiler 10, and a desulfurization reactor 11 is fixedly connected to the outside of the waste heat boiler 10. The desulfurization reactor 11 is fixedly installed on the outside of the sulfur storage tank 12, and a smoke outlet 13 is fixedly installed at the upper end of the desulfurization reactor 11; According toFigures 1-4 As shown, there are three groups of bag vacuum cleaners 4 evenly distributed around the outer wall of the first connecting pipe 2, and the limiting holes 5 inside the bag vacuum cleaners 4 form a snap-fit structure with the limiting rods 7; the limiting rods 7 form a sliding structure with the connector 3, and the limiting rods 7 form an elastic structure with the connector 3 through the telescopic springs 6; the front view of the smoke exhaust port 13 is in a conical structure; When melting metal materials, as the temperature inside the melting furnace 1 rises, the pressure inside the melting furnace 1 also continuously increases. The huge pressure will push the flue gas inside the melting furnace 1 out of the melting furnace 1. The flue gas moves along the first connecting pipe 2 towards the waste heat boiler 10. During the movement, the bag vacuum cleaners 4 inside the connector 3 will absorb the dust and impurities in the flue gas. When the adsorption structure inside the bag vacuum cleaners 4 needs to be replaced after long-term use, pull the limiting rod 7, so that the end of the limiting rod 7 is separated from the limiting hole 5. As the bag vacuum cleaners 4 move downward inside the connector 3, they can be removed, preventing the dust from being discharged outdoors due to insufficient dust suction effect of the bag vacuum cleaners 4 after long-term use. The flue gas inside the waste heat boiler 10 moves through the second connecting pipe 9 and enters the desulfurization reactor 11. Through the reaction of the desulfurization reactor 11 (the electric energy comes from the generator 15), the sulfur element in the flue gas is separated and stored in the sulfur storage tank 12 for recycling. The useless other gases (pollution-free) are discharged outdoors through the smoke exhaust port 13, thus achieving an environmental protection effect.

[0027] The upper end of the waste heat boiler 10 is fixedly connected with a steam turbine 14, and the upper end of the steam turbine 14 is fixedly connected with a generator 15. The lower end of the melting furnace 1 is fixedly installed with support legs 16, and a discharge port 17 is opened inside the melting furnace 1. An output motor 18 is fixedly installed outside the melting furnace 1, and the output end of the output motor 18 penetrates inside the melting furnace 1. A stirrer 19 is fixedly installed at the output end of the output motor 18, and a scraper 20 is fixedly installed at the output end of the output motor 18. A first transmission shaft 23 is fixedly installed at the output end of the output motor 18, and the first transmission shaft 23 is connected with a first central shaft 25 through a first transmission belt 24. The first central shaft 25 is fixedly installed outside the support legs 16, and a first bevel gear 26 is fixedly installed outside the first central shaft 25. A second bevel gear 27 is connected outside the first bevel gear 26, and a second central shaft 28 is fixedly installed inside the second bevel gear 27. The second central shaft 28 is installed outside the melting furnace 1, and the second central shaft 28 is connected with a rotating disk 30 through a second transmission belt 29. The rotating disk 30 is installed outside the melting furnace 1, and a rotating rod 31 is connected to the outside of the rotating disk 30 through a bearing. A condenser 33 is fixedly connected to the outside of the three-way pipe 8, and a deaerator 34 is fixedly connected to the outside of the condenser 33. A third connecting pipe 35 is fixedly connected to the outside of the deaerator 34, and the end of the third connecting pipe 35 is fixedly connected to the outside of the melting furnace 1. A sealing plate 36 penetrates inside the third connecting pipe 35, and the end of the sealing plate 36 is connected with the rotating rod 31 through a bearing; According to Figure 1 、 Figures 5-8 As shown, there are multiple groups of stirrers 19 equidistantly distributed about the output end of the output motor 18, and the stirrers 19 form a rotating structure with the smelting furnace 1; the scrapers 20 are symmetrically distributed left and right about the midpoint of the smelting furnace 1, and the scrapers 20 form a rotating structure with the smelting furnace 1; the first bevel gear 26 and the second bevel gear 27 are meshed, and the second bevel gear 27 forms a rotating structure with the smelting furnace 1 through the second central shaft 28; both ends of the rotating rod 31 form a rotating structure with the sealing plate 36 and the rotating disc 30 respectively, and the rotating disc 30 forms a rotating structure with the smelting furnace 1; the sealing plate 36 forms a sliding structure with the third connecting pipe 35; The heat generated by this structure during smelting is accumulated inside the waste heat boiler 10. The heat inside the waste heat boiler 10 is converted into electrical energy through the action of the steam turbine 14, and the electricity is transmitted to the output motor 18 and the desulfurization reactor 11 through the generator 15. After the output motor 18 is powered on, it will drive the stirrers 19 and the scrapers 20 to rotate through the output end, so as to mix and stir the metal substances inside the smelting furnace 1, accelerating the smelting efficiency and effect. The scraper 20 can scrape off the solutes adhering to the inside of the smelting furnace 1 to prevent waste of resources. Moreover, when the output motor 18 rotates, it will drive the first transmission shaft 23 to rotate. The first transmission shaft 23 drives the first bevel gear 26 to rotate through the connection of the first transmission belt 24. The first bevel gear 26 drives the second bevel gear 27 to rotate through meshing with the second bevel gear 27. The second bevel gear 27 drives the rotating disc 30 to rotate through the connection of the second transmission belt 29. The rotation of the rotating disc 30 will cause the rotating rod 31 connected by the outer bearing to move in a circular motion around the rotating disc 30, thereby generating a pulling force and a pushing force on the sealing plate 36, causing the sealing plate 36 to slide up and down inside the third connecting pipe 35, making the third connecting pipe 35 in an intermittent opening state. The flue gas inside the three-way pipe 8 passes through the condenser 33, and the water vapor in the flue gas condenses into water droplets and enters the deaerator 34. The deaerator 34 is used for deaeration (removing the oxygen and other gases dissolved in the feed water to prevent and reduce the corrosion of the boiler feed water pipes, economizers and other auxiliary equipment). When the third connecting pipe 35 is in the opening state, a certain amount of water is quantitatively transported along the opening (water and fire correction) to prevent the inside of the smelting furnace 1 from being at a high temperature for a long time, thereby causing the loss of internal moisture and affecting the hardness of the smelted metal.
