Description

Technical Field

[0001] This utility model relates to the field of smelting fume treatment technology, and specifically to a smelting fume treatment device. Background Technology

[0002] Smelting is a pyrometallurgical process in which metallic materials and other auxiliary materials are put into a heating furnace to melt and temper them. The materials undergo certain physical and chemical changes in the furnace at high temperature, producing crude metal or metal concentrates and slag.

[0003] Application number CN202122303330.6 discloses a fume extraction device for a casting smelting furnace, relating to the field of flue gas treatment technology. The key technical points of the solution are: it includes an extraction duct, a spray box, a fan, a UV photo-oxidation device, a bag filter, and an exhaust duct. One end of the extraction duct is connected to the smoke inlet of the smelting furnace, and the other end is connected to the exhaust duct. The extraction duct connects sequentially from the smelting furnace to the spray box, fan, UV photo-oxidation device, and bag filter from the exhaust duct. The spray box contains spraying equipment and multiple layers of isolation plates. This solution solves the problems of excessive smoke and odor generated during the smelting process, effectively removing impurities from the smoke and achieving a clean and pollution-free smelting environment.

[0004] However, after the smoke enters the spray box, the spray cooling effect is poor because the smoke has a short path through the spray box. In addition, the multi-layer isolation plates of the device are not easy to disassemble and replace, which leads to a reduction in the filtration effect of the multi-layer isolation plates after long-term use. Therefore, a smelting smoke treatment device is proposed. Utility Model Content

[0005] The main objective of this invention is to provide a smelting fume treatment device that can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A smelting fume treatment device includes a spray box. A first baffle and a second baffle are fixedly installed inside the spray box. There is one first baffle and two second baffles. The first baffle is located between the two second baffles. One end of the first baffle is fixedly connected to one side of the inside of the spray box, and one end of the two second baffles is fixedly connected to the other side of the inside of the spray box.

[0008] The top of the spray box is provided with an installation slot, which has four slots. The four slots are respectively used for the installation and insertion of fine activated carbon filter plates, coarse activated carbon filter plates, fine wire filter screens, and steel wire filter screens.

[0009] By adopting the above technical solution, the first baffle and two second baffles are arranged in an alternating manner, which forces the flue gas to form an S-shaped tortuous path and significantly prolongs the residence time; the spraying equipment is precisely positioned above the baffles to ensure that the flue gas is in full contact with the spray water curtain in the extended path, which greatly improves the cooling and particulate matter capture efficiency.

[0010] Specifically, the top of each of the fine activated carbon filter plate, coarse activated carbon filter plate, fine filament filter screen, and steel wire filter screen is fixedly connected to a connecting plate. A sealing ring is fixedly sleeved on the outside of the connecting plate. The connecting plate is sealed and installed at the entrance of the installation groove. A handle is fixedly attached to the top of the connecting plate.

[0011] By adopting the above technical solution, the connecting plate is embedded in the inlet of the mounting slot, and the sealing ring on its outer side ensures that the top of the spray box remains airtight after the filter assembly is installed, preventing the leakage of unfiltered gas. The handle on the top is easy for the operator to grip, and when the filter assembly needs to be replaced, the connecting plate and the filter assembly can be easily pulled out of the mounting slot together.

[0012] Specifically, the bottom ends of the fine activated carbon filter plate, coarse activated carbon filter plate, fine filament filter screen, and steel wire filter screen are all fixedly connected with insert blocks. The bottom of the spray box has four slots, each located directly below a mounting slot. These slots are used for inserting the insert blocks.

[0013] By adopting the above technical solution, when the filter assembly is inserted into the spray box through the top mounting slot, its bottom plug is simultaneously inserted into the corresponding slot at the bottom of the spray box. This top-sealed installation and bottom-plugging fixation method ensures that the filter assembly is installed vertically and stably inside the spray box, guaranteeing the filtration effect and structural stability.

[0014] Specifically, a spraying device is installed at the top of the spray box, and the spraying device is located directly above the first baffle and the second baffle. A water inlet pipe is connected to the top of the spraying device, and a spray head is provided at the bottom of the spraying device.

[0015] By adopting the above technical solution, the spraying equipment receives water through the water inlet pipe and sprays water downwards through the spray head set at its bottom. The design of the spray head being located directly above the first and second baffles allows the spray water curtain to cover the tortuous airflow channel area formed by the baffles below, so as to fully spray and cool the smoke flowing in it. The extended smoke path ensures that the smoke has enough time to come into contact with the water.

[0016] Specifically, the bottom of the spray box is connected to a drain pipe, and the bottom of the spray box is provided with a drain channel, which is connected to the inside of the drain pipe.

[0017] By adopting the above technical solution, the wastewater generated during the spraying process is collected at the bottom of the spray box. The drainage channel at the bottom of the box collects this wastewater and guides it to the drain pipe, which then continuously discharges it out of the box, preventing water accumulation inside the box from affecting the spraying and filtration effect and maintaining the normal working environment inside the spray box.

[0018] Specifically, one end of the spray box is connected to an air inlet pipe, and the other end of the spray box is connected to an air outlet pipe.

[0019] By adopting the above technical solution, the dust-containing and odorous fumes generated during the smelting process are introduced into the spray box through the air inlet pipe for treatment. After passing through the internal baffle to extend the path, the spray equipment for cooling, and the purification of the multi-layer filter components, the treated clean gas is finally discharged from the spray box through the air outlet pipe and enters the subsequent emission or treatment stage.

[0020] The beneficial effects of this utility model are:

[0021] The smelting fume treatment device of this utility model has a first baffle and two second baffles arranged in an alternating manner, which forces the flue gas to form an S-shaped tortuous path and significantly prolongs the residence time; the spray equipment is precisely covered above the baffles to ensure that the flue gas is in full contact with the spray water curtain in the extended path, which greatly improves the cooling and particulate matter capture efficiency.

[0022] The smelting fume treatment device described in this utility model adopts a top-insertion design for all filter components. The airtight fixing is achieved by embedding the connecting plate with the sealing ring into the mounting groove. The bottom insert and slot cooperate to ensure vertical stability. The special handle on the top allows the operator to quickly insert and remove the filter unit without tools, which greatly reduces the maintenance difficulty and time cost.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] As one embodiment of this utility model, such as Figures 1-3 As shown, the present invention provides a smelting fume treatment device, including a spray box 6. A first baffle 7 and a second baffle 8 are fixedly installed inside the spray box 6. There is one first baffle 7 and two second baffles 8. The first baffle 7 is located between the two second baffles 8. One end of the first baffle 7 is fixedly connected to one side of the inside of the spray box 6, and one end of the two second baffles 8 is fixedly connected to the other side of the inside of the spray box 6.

[0030] The top of the spray box 6 is provided with an installation slot 11. There are four installation slots 11, which are respectively used for the installation and insertion of fine activated carbon filter plate 10, coarse activated carbon filter plate 15, fine wire filter screen 16, and steel wire filter screen 17.

[0031] In use, the fumes generated during the smelting process enter the spray box 6 through the air inlet pipe 1 and are guided by the unique layout of the first baffle 7 and the second baffle 8. The first baffle 7 is located between the two second baffles 8, and the first baffle 7 and the second baffle 8 are respectively fixed to the inner walls of both sides of the spray box 6, forcing the fumes to form a longer, tortuous flow path such as an S-shape in the box, thereby prolonging their residence time in the box. The fine activated carbon filter plate 10, the coarse activated carbon filter plate 15, the fine filament filter screen 16, and the steel wire filter screen 17 can be inserted into the interior of the spray box 6 from these four mounting slots 11 and extend downwards. These filter components provide installation positions for subsequent multi-layer filtration of the sprayed fumes.

[0032] It should be noted that the lengths of the first baffle 7 and the second baffle 8 are less than the width inside the spray box 6.

[0033] This utility model also includes a connecting plate 5 fixedly connected to the top of each of the fine activated carbon filter plate 10, coarse activated carbon filter plate 15, fine filament filter screen 16, and steel wire filter screen 17. A sealing ring 9 is fixedly sleeved on the outside of the connecting plate 5. The connecting plate 5 is sealed and installed at the entrance of the mounting groove 11. A handle 4 is fixedly attached to the top of the connecting plate 5.

[0034] When in use, the connecting plate 5 is embedded in the inlet of the mounting groove 11. The sealing ring 9 on its outer side ensures that the top of the spray box 6 remains airtight after the filter assembly is installed, preventing the leakage of unfiltered gas. The handle 4 on the top is easy for the operator to grip. When the filter assembly needs to be replaced, the connecting plate 5 together with the filter assembly can be easily pulled upward from the mounting groove 11.

[0035] This utility model also includes that the bottom ends of the fine activated carbon filter plate 10, the coarse activated carbon filter plate 15, the fine filament filter screen 16, and the steel wire filter screen 17 are all fixedly connected with insert blocks 13. The bottom of the spray box 6 is provided with a slot 14. There are four slots 14, and the four slots 14 are located directly below the four mounting slots 11. The slots 14 are used for inserting the insert blocks 13.

[0036] When in use, when the filter assembly is inserted into the spray box 6 through the mounting slot 11 at the top, the insert block 13 at the bottom is simultaneously inserted into the corresponding slot 14 at the bottom of the spray box 6. This top-sealed installation and bottom-insertion fixing method ensures that the filter assembly is installed vertically and stably inside the spray box 6, guaranteeing the filtration effect and structural stability.

[0037] The present invention also includes a spraying device 2 installed on the top of the spray box 6, the spraying device 2 being located directly above the first baffle 7 and the second baffle 8, the top of the spraying device 2 being connected to a water inlet pipe 3, and the bottom of the spraying device 2 being provided with a spray head 20.

[0038] In use, the spraying device 2 receives water through the water inlet pipe 3 and sprays water downward through the spray head 20 set at its bottom. Its position is designed to be directly above the first baffle 7 and the second baffle 8, so that the spray water curtain can cover the tortuous airflow channel area formed by the baffle below, and fully spray and cool the smoke flowing in it. The extended smoke path ensures that the smoke has enough time to come into contact with the water.

[0039] The present invention also includes a drain pipe 18 connected to the bottom end of the spray box 6, and a drain channel 19 provided at the bottom of the spray box 6, the drain channel 19 being internally connected to the drain pipe 18.

[0040] During use, the wastewater generated during the spraying process is collected at the bottom of the spray box 6. The drainage channel 19 at the bottom of the box collects this wastewater and guides it to the drain pipe 18. Then, it is continuously discharged out of the box through the drain pipe 18 to prevent water accumulation inside the box from affecting the spraying and filtration effect and to maintain the normal working environment inside the spray box 6.

[0041] It should be noted that the spray box 6 is located at the bottom of the first baffle 7 and the second baffle 8 and is set at an angle downwards to facilitate the outflow of water.

[0042] This utility model also includes an air inlet pipe 1 connected to one end of the spray box 6 and an air outlet pipe 12 connected to the other end of the spray box 6.

[0043] During use, the dust-laden and odorous fumes generated during the smelting process are introduced into the spray box 6 through the air inlet pipe 1 for treatment. After passing through the internal baffle to extend the path, the spray equipment 2 for spraying and cooling, and the purification of the multi-layer filter components, the treated clean gas is finally discharged from the spray box 6 through the air outlet pipe 12 and enters the subsequent emission or treatment stage.

[0044] In use, the fumes generated during the smelting process first enter the spray box 6 through the air inlet pipe 1. Since the spray box 6 has a uniquely arranged first baffle 7 and second baffle 8 fixedly installed inside, with the first baffle 7 located between the two second baffles 8 and one end fixedly connected to the inner walls of both sides of the spray box 6, the movement path of the fumes in the spray box 6 is extended. When the fumes flow in the spray box 6, the spraying device 2 installed at the top of the spray box 6 starts to work. The water inlet pipe 3 delivers water to the spraying device 2, and the spraying device 2 sprays water out through the spray head 20 at the bottom to spray and cool the fumes. The extended movement path allows the fumes to have more contact time with the spraying water, thereby improving the spraying and cooling effect.

[0045] After being cooled by spraying, the smoke continues to rise. At this time, the fine activated carbon filter plate 10, the coarse activated carbon filter plate 15, the fine wire filter screen 16, and the steel wire filter screen 17 play a filtering role. These filter components are inserted into the spray box 6 from the installation groove 11, and the bottom insert 13 is inserted into the slot 14 at the bottom of the spray box 6 for fixation, so as to achieve multi-layer filtration of impurities in the smoke, remove odors and fine particles, etc. The filtered clean gas is discharged from the spray box 6 through the exhaust pipe 12 and enters the subsequent processing process.

[0046] Wastewater generated during the spraying process flows into the drain pipe 18 through the drainage channel 19 at the bottom of the spray box 6 to ensure the normal working environment inside the spray box 6. In addition, when the filtration effect of the fine activated carbon filter plate 10, coarse activated carbon filter plate 15, fine filament filter screen 16, and steel wire filter screen 17 decreases after a period of use, the operator can easily pull the connecting plate 5 out of the mounting slot 11 through the handle 4 to disassemble and replace the filter components, ensuring the continuous and stable filtration performance of the device.
