Description

Technical Field

[0001] This utility model relates to the field of flue gas treatment technology, and in particular to a flue gas treatment device for a smelting furnace. Background Technology

[0002] The smelting furnace uses a 200-2500Hz medium-frequency power supply for induction heating, with a power range of 20-2500KW. Based on its characteristics, it can also be called a medium-frequency electric furnace. It is mainly used for smelting and heating precious metals such as gold, platinum, silver, copper, iron, stainless steel, aluminum alloys, and other metals. During the smelting process, a large amount of flue gas is often generated. This flue gas is high in temperature and has a complex composition; direct emission would pollute the environment.

[0003] In existing smelting furnace flue gas treatment devices, high-temperature flue gas is usually directly introduced into the treatment device and purified through built-in filter components during operation. However, since the flue gas enters the filtration stage without being cooled, its continuous high temperature can easily cause irreversible damage to the physical and chemical properties of the filter material, shorten the component life, and increase operating costs. At the same time, relying on a single filtration method is not enough to completely remove multiple pollutants in the flue gas, resulting in an unsatisfactory overall purification effect and insufficient stability of emission indicators, thus affecting the final effect of flue gas treatment and environmental compliance. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a smelting furnace flue gas treatment device, which has the advantages of cooling and reducing the temperature of flue gas and achieving good flue gas treatment effect, thereby solving the problems mentioned in the background technology.

[0006] Preferably, a bushing is fixedly installed at the middle position of the top surface of the housing, and a second connecting rod is provided through the bushing. A cleaning brush is fixedly connected to the second connecting rod below the filter screen. A second helical gear is fixedly connected to the top end of the second connecting rod.

[0007] Preferably, one end of the rotating rod penetrates one side surface of the housing, and a synchronous pulley is fixedly connected to one end of the rotating rod and one end of the first connecting rod, and a synchronous belt is installed between the synchronous pulleys.

[0008] Preferably, there are two filters, which are evenly distributed on both sides of the inside of the housing, and the cleaning brush is matched with the filters.

[0009] Preferably, an air inlet pipe is fixedly connected to the front surface of the housing, and an exhaust pipe is fixedly connected to one side of the top surface of the housing.

[0010] Preferably, a water inlet pipe is fixedly connected to one side surface of the housing below the water pump.

[0012] Preferably, a drain pipe is fixedly connected to the middle position of the bottom surface of the box, and a valve is fixedly installed on the drain pipe.

[0013] Compared with the prior art, the present invention provides a smelting furnace flue gas treatment device, which has the following beneficial effects: (1) In this utility model, after the flue gas enters the box through the air inlet pipe, the water pump on one side of the box is started. The water in the box is transported to the spray pipe through the water pipe and the spray nozzle on the spray pipe forms water mist. This not only effectively reduces the dust in the flue gas, but also reduces the temperature of the flue gas, avoiding damage to the subsequent filter components caused by high temperature, which is conducive to extending the service life of the filter components. In addition, the flue gas after dust reduction and cooling is filtered again through the filter screen to further remove the residual impurities, comprehensively improve the flue gas purification effect, and ensure that the final emission meets the environmental protection standards.

[0014] (2) In this utility model, the motor on one side of the box is started, the motor drives the rotating rod to rotate, and drives the stirring blade on it to rotate, stirring the water at the bottom of the box, thereby increasing the contact area between the water and the flue gas, improving the heat exchange efficiency, and thus accelerating the cooling rate of the flue gas. At the same time, the rotating rod drives the first connecting rod and the first helical gear at its end to rotate through the synchronous wheel and synchronous belt. The first helical gear meshes with the second helical gear at the top of the second connecting rod, thereby driving the second connecting rod to rotate, so that the cleaning brush installed on it can automatically clean the surface of the filter screen, effectively removing the dust accumulated on the filter screen, preventing blockage, and ensuring the continuous and stable operation of the filter assembly.

[0020] Please see Figure 1-4 A smelting furnace flue gas treatment device includes a housing 1. A spray pipe 2 is fixedly connected inside the housing 1, and a nozzle 3 is fixedly installed on the spray pipe 2. A motor 8 is fixedly installed on one side surface of the housing 1, and a rotating rod 5 is fixedly connected to the output end of the motor 8. An agitator 4 is fixedly connected to the rotating rod 5 inside the housing 1. When the motor 8 on one side surface of the housing 1 is started, the motor 8 drives the rotating rod 5 to rotate, causing the agitator 4 on the rotating rod 5 to rotate. This agitates the water at the bottom of the housing 1, increasing the contact area between the water and the flue gas, and further improving the cooling rate of the flue gas. A water pump 6 is fixedly installed at the top. The water pump 6 is connected to the housing 1 through a water suction pipe and to the spray pipe 2 through a water delivery pipe. A filter screen 18 is fixedly installed inside the housing 1 above the spray pipe 2. When the water pump 6 is started on one side surface of the housing 1, the water pump 6 delivers water from the housing 1 to the spray pipe 2 through the water suction pipe and the water delivery pipe. The water mist is then sprayed out through the nozzles 3 on the spray pipe 2. This not only reduces dust in the flue gas but also cools the flue gas, reducing its temperature and preventing damage to the filter components in the housing 1 due to excessive temperature, thus extending the service life of the filter components.

[0021] Please see Figure 1 and Figure 2A bushing is fixedly installed at the middle position of the top surface of the housing 1, and a second connecting rod 17 is inserted through the bushing. A cleaning brush 15 is fixedly connected to the second connecting rod 17 below the filter screen 18. A second helical gear 16 is fixedly connected to the top end of the second connecting rod 17. A baffle is fixedly connected to one side of the top surface of the housing 1, and a bushing is fixedly installed on one side of the baffle. A first connecting rod 12 is inserted through the bushing, and a first helical gear 14 is fixedly connected to one end of the first connecting rod 12. The first helical gear 14 meshes with the second helical gear 16. The helical gear 16 is matched to maintain normal transmission. When the rotating rod 5 rotates, it drives the synchronous pulley 10 to rotate. Through the use of the synchronous belt 11, the first connecting rod 12 can be driven to rotate. When the first connecting rod 12 rotates, it drives the first helical gear 14 to rotate. When the first helical gear 14 rotates, it drives the second helical gear 16 at the top of the second connecting rod 17 to rotate, so that the cleaning brush 15 on the second connecting rod 17 rotates, which can automatically clean the dust adhering to the filter screen 18 and prevent dust from accumulating on the filter screen 18 and causing blockage.

[0022] Please see Figure 1 and Figure 2 One end of the rotating rod 5 penetrates one side surface of the housing 1. One end of the rotating rod 5 and one end of the first connecting rod 12 are fixedly connected to a synchronous pulley 10, and a synchronous belt 11 is installed between the synchronous pulleys 10. The synchronous pulleys 10 and the synchronous belt 11 can drive the first connecting rod 12 to rotate. In conjunction with the use of the first helical gear 14 and the second helical gear 16, the cleaning brush 15 on the second connecting rod 17 can be driven to rotate, which can automatically clean the dust adhering to the filter screen 18.

[0023] Please see Figure 1 and Figure 2 There are two filters 18, which are evenly distributed on both sides of the inside of the housing 1. The use of two filters 18 can improve the filtration effect of flue gas. The cleaning brush 15 is matched with the filter 18, and the use of the cleaning brush 15 can facilitate automatic cleaning of the filter 18.

[0024] Please see Figure 1 and Figure 3 An air inlet pipe 19 is fixedly connected to the front surface of the housing 1, through which flue gas can be introduced into the housing 1; an exhaust pipe 13 is fixedly connected to one side of the top surface of the housing 1, through which the treated flue gas can be discharged.

[0025] Please see Figure 1 and Figure 3A water inlet pipe 7 is fixedly connected to one side surface of the housing 1 below the water pump 6, through which cold water can be added to the housing 1.

[0026] Please see Figure 1 and Figure 3 Support legs 9 are fixedly connected to both sides of the bottom surface of the box 1. There are multiple support legs 9, and the multiple support legs 9 are evenly distributed in pairs on both sides of the bottom surface of the box 1. The support legs 9 support the box 1 and maintain the stability of the box 1 during use.

[0027] Please see Figure 1 and Figure 3 A drain pipe is fixedly connected to the middle of the bottom surface of the tank 1, and a valve is fixedly installed on the drain pipe. By opening the valve, the water in the tank 1 can be drained through the drain pipe.

[0028] The control switch control circuit can be implemented by simple programming by those skilled in the art. It is common knowledge in the field. Since it is only used and not modified, the control method and circuit connection will not be described in detail.

[0029] Working principle: In use, flue gas is introduced into the housing 1 through the inlet pipe 19. The water pump 6 on one side surface of the housing 1 is started. The water pump 6 transports water from the housing 1 to the spray pipe 2 through the water supply pipe. The water mist is then sprayed out through the nozzles 3 on the spray pipe 2. This not only reduces dust in the flue gas but also cools the flue gas, lowering its temperature and preventing damage to the filter components in the housing 1 due to excessive temperature. This helps extend the service life of the filter components. Secondly, the use of the filter screen 18 further filters the flue gas after dust reduction, reducing impurities and further improving the treatment effect to meet emission standards. The motor 8 on one side surface of the housing 1 is started, and the motor 8 drives the rotating rod 5. The rotation of the rotating rod 5 causes the agitator 4 on the rotating rod 5 to rotate, which agitates the water at the bottom of the housing 1, increasing the contact area between the water and the flue gas and further improving the cooling rate of the flue gas. While rotating the rotating rod 5, it drives the synchronous pulley 10 to rotate. Through the use of the synchronous belt 11, it drives the first connecting rod 12 to rotate. While rotating the first connecting rod 12, it drives the first helical gear 14 to rotate. While rotating the first helical gear 14, it drives the second helical gear 16 at the top of the second connecting rod 17 to rotate, which causes the cleaning brush 15 on the second connecting rod 17 to rotate. This automatically cleans the dust adhering to the filter screen 18, preventing dust from accumulating on the filter screen 18 and causing blockage, thus ensuring its normal subsequent use.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
