Description
Technical Field

[0002] Industrial furnaces that perform thermal processing on various materials or workpieces during metallurgical production. Thermal processing is a process characterized by the heating of materials or workpieces, such as roasting, smelting, heating, heat treatment, drying, etc. Most production links of iron and steel metallurgy and non-ferrous metallurgy are inseparable from furnaces. The energy consumption of the metallurgical industry depends largely on the energy consumption of various metallurgical furnaces.
[0003] During the metallurgical process, a large amount of smoke will be generated when the fuel is burned. If the smoke is not treated and discharged into the atmosphere, it will cause serious air pollution. In order to avoid this situation, existing metallurgical boilers will treat the smoke generated.
[0004] However, the dust removal equipment currently used in metallurgical furnaces often directly injects smoke into a water tank, and the water in the water tank is used to adsorb the smoke, thereby achieving smoke treatment. Although this method can achieve smoke treatment, the direct injection of smoke during the treatment process will cause large bubbles to be generated in the water tank, which can easily lead to the inability of the smoke to fully contact the water in the water tank, thereby affecting the treatment effect. For this reason, an efficient dust removal device for metallurgical furnaces is proposed to solve the above problems. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] Reference Figure 1-Figure 2 , the utility model provides an embodiment: a high-efficiency dust removal device for a metallurgical furnace, comprising a metallurgical furnace body 1, a dust removal tank 2 is installed on the outside of the metallurgical furnace body 1, a mounting frame 12 is fixedly connected to the outside of the metallurgical furnace body 1, the dust removal tank 2 is fixedly connected to the middle of the mounting frame 12, an exhaust pipe 4 is fixedly connected to one side of the top of the dust removal tank 2, an air intake pipe 3 is fixedly connected to the top of the metallurgical furnace body 1, the other end of the air intake pipe 3 is connected to the dust removal tank 2, a rotating rod 6 is rotatably connected inside the dust removal tank 2, an impeller 7 is fixedly connected to the bottom of the rotating rod 6, the output end of the air intake pipe 3 faces the outside of the impeller 7, and a filter screen 10 is fixedly connected inside the dust removal tank 2;
[0033] Specifically, the smoke generated when the metallurgical furnace body 1 is working will enter the air inlet pipe 3 and be transported to the bottom of the dust removal tank 2 through the air inlet pipe 3. At this time, the smoke will be mixed with the water stored in the dust removal tank 2 to achieve the treatment of the smoke. While the smoke is injected, one side of the impeller 7 will be blown. At this time, the impeller 7 will rotate inside the dust removal tank 2 due to the thrust, which can drive the water to rotate, thereby facilitating the contact between the water and the smoke. At the same time, the rotating impeller 7 will break up the transported columnar smoke air and disperse it into multiple small bubbles, so that the smoke can fully contact the water, thereby improving the smoke treatment effect.
[0034] Reference Figure 2 The top of the rotating rod 6 is fixedly connected with a cleaning assembly, the cleaning assembly includes a rotating rod 8, the rotating rod 8 is fixedly connected to the top of the rotating rod 6, the top of the rotating rod 8 is fixedly connected with a cleaning brush 9, and the top of the cleaning brush 9 is in contact with the bottom of the filter screen 10;
[0035] Specifically, while the smoke drives the impeller 7 to rotate, it can also drive the rotating rod 6 and the rotating rod 8 to rotate, so that the cleaning brush 9 can rotate at the bottom of the filter 10. The cleaning brush 9 can clean the lower surface of the filter 10 to avoid clogging of the filter 10 caused by direct filtration of smoke, thereby increasing the service life of the filter 10 and improving the smoke and dust treatment effect.
[0036] Reference Figure 2-Figure 3 The outer side of the dust removal tank 2 is fixedly connected with a connecting bin 13, and the top of the connecting bin 13 is fixedly connected with a mud discharge assembly, which includes a shell 14, which is fixedly connected to the top of the connecting bin 13, and the top of the shell 14 is fixedly connected with a motor 15, and the output end of the motor 15 is fixedly connected with a rotating shaft 16, and the outer periphery of the rotating shaft 16 is fixedly connected with a spiral blade 17, and the outer side of the shell 14 is fixedly connected with a mud discharge pipe 18, and a notch 19 is provided on the outer side of the dust removal tank 2, and the connecting bin 13 and the dust removal tank 2 are connected through the notch 19;
[0037] Specifically, when the dust removal tank 2 is performing dust removal, smoke accumulates at the bottom of the dust removal tank 2 and enters into the connecting chamber 13 through the notch 19. After a period of use, a lot of dust and mud will accumulate at the bottom of the dust removal tank 2. At this time, the driving motor 15 can be used to drive the rotating shaft 16 to rotate, so that the spiral blades 17 can rotate in a circle, thereby transporting the dust and mud at the bottom of the dust removal tank 2 upward and discharging it from the mud discharge pipe 18. In this way, the dust and mud can be cleaned while ensuring the long-term use of the dust removal tank 2, so as to avoid the shutdown of the device for cleaning, thereby greatly improving the cleaning efficiency.
[0038] Reference Figure 2-Figure 3A water inlet pipe 5 is fixedly connected to the top of the metallurgical furnace body 1, and the bottom output end of the water inlet pipe 5 is located at the top of the filter screen 10. A heat-conducting copper tube 11 is fixedly connected to the dust removal tank 2. The top end of the heat-conducting copper tube 11 is the output end, and the bottom end of the heat-conducting copper tube 11 is the input end. A communicating vessel is formed between the outer shell 14 and the dust removal tank 2, and the upper liquid level of the water body inside the dust removal tank 2 is lower than the inlet of the mud discharge pipe 18;
[0039] Specifically, the water inside the dust removal tank 2 will be continuously consumed during the dust removal process. Therefore, new water can be injected from the water inlet pipe 5 after a period of time to ensure the normal treatment of the smoke and dust. At the same time, after the water passes through the filter 10, the filter 10 can be simply cleaned, thereby further extending the service life of the filter 10. At the same time, when the smoke and dust are being treated, the temperature of the water inside the dust removal tank 2 will continue to rise. At this time, the external water source can be connected to the input end of the heat-conducting copper tube 11. After the water source passes through the heat-conducting copper tube 11, the heat inside the dust removal tank 2 can be absorbed to increase the temperature. Then, when the water source is discharged from the heat-conducting copper tube 11, it can be used for other purposes, thereby recovering the waste heat in the smoke and dust treatment and greatly reducing heat waste. Finally, the water inside the dust removal tank 2 is lower than the inlet of the mud discharge pipe 18 to avoid the water being directly discharged from the mud discharge pipe 18, thereby ensuring the normal treatment of the smoke and dust.
[0040] Working principle: The flue gas generated by the metallurgical furnace body 1 will enter the dust removal tank 2 from the air inlet pipe 3, and the gas pumped into the flue gas will drive the impeller 7 to rotate, so as to slowly stir the water inside the dust removal tank 2. The large bubbles of the flue gas will also be impacted and split into multiple small bubbles, so that the flue gas can fully contact with the water body, thereby improving the flue gas treatment effect;
[0041] Secondly, the filter 10 can filter the remaining smoke and dust after the water treatment again to further improve the smoke treatment effect, and when the smoke and dust enter and drive the impeller 7 to rotate, it can also drive the rotating rod 6 to rotate, thereby driving the rotating rod 8 and the cleaning brush 9 to rotate, and the bottom of the filter 10 can be cleaned, thereby avoiding the clogging of the filter 10 caused by long-term use, thereby extending the service life of the filter 10;
[0042] Finally, when the dust and mud accumulated at the bottom of the dust removal tank 2 accumulates to a certain height, the driving motor 15 can be used to drive the rotating shaft 16 to rotate. At this time, the rotating shaft 16 will drive the spiral blades 17 to rotate, and then the dust and mud will be transported upward from the outside of the dust removal tank 2. When it reaches the position of the mud discharge pipe 18, it will be discharged from the mud discharge pipe 18, so as to clean the dust and mud, so that the dust removal device can be used continuously for a long time; when the water body inside the dust removal tank 2 is reduced, new water body can also be injected from the water inlet pipe 5 to ensure the continuous dust removal; because the smoke and dust will also bring a certain degree of heat when it is transported from the air inlet pipe 3 to the inside of the dust removal tank 2, the device installs a heat-conducting copper pipe 11 inside the dust removal tank 2, and injects external water body from the bottom inlet of the heat-conducting copper pipe 11, and then discharges it from the top outlet, so that the heat carried by the water body inside the dust removal tank 2 can be recovered, thereby reducing heat waste.
[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
