Description

Technical Field

[0001] The utility model relates to the technical field of processing of ferrous metal smelting and rolling products, in particular to a flue gas treatment device for processing ferrous metal smelting and rolling products. Background Art

[0002] Ferrous metal smelting and rolling refer to the process of converting iron ore and other raw materials into various steel and non-ferrous metal products through smelting and rolling processes. As a basic industrial raw material, steel is widely used in various fields such as construction, transportation, machinery, electric power, and aviation.

[0003] During the processing of ferrous metal smelting and rolling products, a large amount of pollutants such as waste gas and dust will be generated, which will cause serious impacts on the environment. In order to reduce pollutant emissions and ensure environmental and human health, ferrous metal smelting and rolling product processing enterprises need to use effective flue gas treatment equipment for treatment.

[0004] Existing treatment devices generally purify flue gas through the forms of cyclone cloth dust removal and bag dust removal. However, each time the device treats flue gas, it needs to go through multiple processes. At the same time, it needs to be cleaned after being used for a period of time, and the flue gas treatment is not fast enough. Moreover, the temperature of the flue gas emitted from ferrous metal smelting is relatively high, which is likely to cause certain damage to the equipment itself during the treatment process. Content of the Utility Model

[0005] In view of the above problems of low treatment efficiency and too high waste gas temperature, the present utility model is proposed.

[0006] To solve the above technical problems, the present utility model provides the following technical solution: A flue gas treatment device for processing ferrous metal smelting and rolling products, including a filter shell, an air inlet is arranged on one side of the filter shell, an air outlet is arranged at the upper end of the filter shell, two groups of volute chambers are symmetrically installed on both sides of the inner wall of the filter shell, a partition is arranged inside the volute chamber, a diversion pipe is installed on one side of the volute chamber, and both ends of the diversion pipe communicate to both sides of the partition;

[0007] A hollow rotating shaft is inserted and connected to the upper end of the volute chamber, an impeller is installed on one side of the hollow rotating shaft, a water inlet is opened on one side of the hollow rotating shaft, the impeller and the water inlet are separated by the partition, a fan blade is installed at the end of the hollow rotating shaft away from the impeller, the fan blade is installed obliquely and water spraying holes are opened on the surface.

[0008] Preferably, a shunt pipe is installed on one side of the filter shell, and the shunt pipe communicates with the input end of the volute chamber.

[0009] Preferably, a support platform is placed on one side of the filter shell, and a distillation barrel, a distiller, a refrigerator, and a water storage barrel are installed on the upper end of the support platform.

[0010] Preferably, a sewage discharge pipe is connected to the lower end of the filter housing. A second water pump is installed at one end of the sewage discharge pipe away from the filter housing. The output end of the second water pump is connected to the distillation barrel, and a distiller is fixedly installed on one side of the distillation barrel.

[0011] Preferably, a cooling pipe is connected to the upper end of the distillation barrel, and a refrigerator placed on the upper end of the support platform is connected to one side of the cooling pipe.

[0012] Preferably, the lower end of the cooling pipe is connected to a water storage bucket. One side of the water storage bucket is connected to the input end of the first water pump, and the output end of the first water pump is connected to a shunt pipe.

[0013] Advantages of the present utility model:

[0014] 1. The rotation of the hollow rotating shaft is driven by the water flow. The hollow rotating shaft drives the fan blades to rotate, so that the water flow is ejected from the spray holes formed on the surface of the fan blades. At the same time, the fan blades are installed obliquely, and the rotation of the hollow rotating shaft will drive the fan blades to generate wind energy to disrupt the flow of the flue gas. When the flue gas is continuously sprayed by the sprinkling devices on both sides, the dust and waste carried in the flue gas adhere to the water and flow into the bottom of the filter housing. At the same time, the temperature of the flue gas can be reduced to prevent the high-temperature flue gas from damaging the device.

[0015] 2. The waste water in the distillation barrel is evaporated into water vapor by the distiller. The water vapor rises and flows into the cooling pipe. The cooling pipe then uses the refrigerator to cause a physical change in the water vapor inside and between them, condensing into water droplets and converging into the water storage bucket. The water storage bucket then uses the first water pump to introduce the water flow inside it into the shunt pipe, supplying water source to the flue gas treatment device, so that the temperature of the flue gas can be reduced when spraying water, and a set of water resource recycling is achieved.

DETAILED DESCRIPTION

[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings. Example

[0025] Reference Figures 1-4 , which is the first embodiment of the utility model, provides a fume treatment device for processing ferrous metal smelting rolled products, including a filter shell 1, an air inlet 2 is arranged on one side of the filter shell 1, an air outlet 3 is arranged on the upper end of the filter shell 1, and there is a sufficient distance between the air inlet 2 and the air outlet 3 for the exhaust gas to flow together, two groups of volutes 4 are symmetrically installed on both sides of the inner wall of the filter shell 1, and the volutes are distributed between the air inlet 2 and the air outlet 3. A partition 7 is arranged on the inner side of the volute 4, and the partition 7 divides the volute 4 into upper and lower spaces. A guide pipe 9 is installed on one side of the volute 4, and both ends of the guide pipe 9 are connected to both sides of the partition 7, so that the upper and lower spaces of the partition 7 are connected;

[0026] A hollow shaft 5 is inserted and connected to the upper end of the volute 4, and the hollow shaft 5 also passes through the partition 7, and the hollow shaft 5 can be positioned and rotated in the volute 4. An impeller 6 is installed on one side of the hollow shaft 5, and three pieces of the impeller 6 are installed around the hollow shaft 5. A water inlet 8 is opened on one side of the hollow shaft 5, and the water inlet 8 is located on the side away from the impeller 6. The impeller 6 and the water inlet 8 are separated by the partition 7. The end of the hollow shaft 5 away from the impeller 6 is connected with a fan blade 10, and the fan blade 10 is installed on an inclined surface and a water spray hole is opened on the surface.

[0027] A shunt pipe 14 is installed on one side of the filter housing 1 . The shunt pipe 14 is a four-way pipe connected to two pairs of input ends of the volute 4 respectively, so that water can enter the volute 4 and flow in a spiral manner in the volute 4 .

[0028] During use, the flue gas first enters the interior of the filter housing 1 through the air inlet 2. When it is about to come out of the air outlet 3, the device starts at this time. The water flow surges into the input ports of the two groups of spiral chambers 4 through the shunt pipe 14. When the water flow enters the interior of the spiral chamber 4, it will first pass through the lower end of the partition plate 7. The partition plate 7 plays a role in separating the flow. The first thrust of the water flow will pass through the impeller 6 fixedly connected to one side of the hollow rotating shaft 5, pushing the impeller 6 to rotate in the direction of the water flow. Then the hollow rotating shaft 5 will start to rotate. When the water flow in the chamber where the impeller 6 is located is full, the water flow will surge into the diversion pipe 9. At this time, the first thrust of the water flow will push the impeller 6 to rotate again along the inner track of the spiral chamber 4. The impeller 6 drives the hollow rotating shaft 5 to rotate, and the fan blades 10 are installed obliquely, so that when the hollow rotating shaft 5 rotates, it will drive the fan blades 10 to generate wind energy to disrupt the flow of the flue gas. The diversion pipe 9 communicates with the upper and lower chambers separated by the partition plate 7. Then the water flow flows into the water storage chamber above the partition plate 7 through the diversion pipe 9. When the water flow in the chamber is full, the water flow will surge into the water inlet 8 opened on one side of the hollow rotating shaft 5. The water inlet 8 is located at the upper end of the partition plate 7. At this time, the function of the partition plate 7 is to make the power of the water flow act on the rotation first and then drive into the access end of the water outlet. When the water flow enters the interior of the hollow rotating shaft 5, it will surge along the channel into the fan blades 10 installed on the periphery of the hollow rotating shaft 5. Then the water flow will be ejected from the spray holes opened on the surface of the fan blades 10. At this time, the flue gas is continuously sprayed by the sprinkler devices on both sides, so that the dust and waste in the flue gas adhere to the water and flow to the bottom of the filter housing 1, and at the same time, the flue gas can be cooled down. Embodiment

[0029] Refer to Figures 1-5 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a support platform 11 is placed on one side of the filter housing 1. A distillation barrel 17, a distiller 18, a refrigerator 20 and a water storage barrel 12 are installed on the upper end of the support platform 11 by threading.

[0030] A sewage discharge pipe 15 is connected to the lower end of the filter housing 1. A second water pump 16 is installed at one end of the sewage discharge pipe 15 away from the filter housing 1. The output end of the second water pump 16 is communicated with the distillation barrel 17. When the flue gas filtering device produces waste water, it will be sucked into the distillation barrel 17 from the bottom channel of the filter housing 1 through the sewage discharge pipe 15 by the second water pump 16. A distiller 18 is fixedly installed on one side of the distillation barrel 17. The distiller 18 is composed of structures such as an evaporator, a degassing system, a feeding system, a heating system, and a heat transfer pipe. By heating the water, its water vapor pressure rises. When it is equal to the external atmospheric pressure, the liquid boils into steam.

[0031] A cooling pipe 19 is connected to the upper end of the distillation barrel 17. The cooling pipe 19 is made of heat dissipation material, and a refrigerator 20 placed on the upper end of the support platform 11 is connected to one side of the cooling pipe 19. The refrigerator 20 is composed of structures such as a compressor, a condenser, an expansion valve, and a cold air delivery pipe. By heat conversion, cold air is delivered into the cooling pipe 19.

[0032] The lower end of the cooling pipe 19 is connected to a water storage bucket 12. When steam enters the cooling pipe 19, the water vapor exchanges heat with the cold air transferred by the cooler 20, transferring the heat of the water vapor to the cold air. Thus, the water vapor cools and condenses into a liquid state, flowing along the inner wall of the cooling pipe 19 and into the water storage bucket 12 connected by a pipe at the lower end. One side of the water storage bucket 12 is connected to the input end of the first water pump 13, and the output end of the first water pump 13 is connected to the shunt pipe 14. Then, through the first water pump 13, the filtered water source is pumped from the water storage bucket 12 into the shunt pipe 14, enabling the filtering device to replenish the water source again.

[0033] During use, when the wastewater accumulates at the bottom of the filter housing 1, a sewage pipe 15 is installed at the lower end of the filter housing 1, and the other end thereof is connected to the input end of the second water pump 16. The output end of the second water pump 16 is connected to one side of the distillation barrel 17. Thus, the accumulated water in the filter housing 1 can be pumped into the interior of the distillation barrel 17 through the second water pump 16. A distiller 18 is installed on one side of the distillation barrel 17. The distiller 18 evaporates the wastewater in the distillation barrel 17 into water vapor through heat conversion. The water vapor rises and flows into the interior of the cooling pipe 19. One side of the cooling pipe 19 is connected to the cooler 20 through a pipe. The cooler 20 generates cold air through heat conversion and enters the interior of the cooling pipe 19 to produce a physical change with the water vapor therein, condensing into water droplets that gather together, and then flowing into the water storage bucket 12 connected to the lower end of the cooling pipe 19. The water storage bucket 12 then guides the water flow therein into the shunt pipe 14 through the first water pump 13, inputting a water source for the flue gas treatment device, enabling the water flow to reduce the temperature of the flue gas during spraying and achieving a set of water resource recycling.

[0034] The remaining structure is the same as that of Embodiment 1.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
