Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical equipment, in particular to an energy-saving and environmentally friendly metal copper production fume filtering device. Background Art

[0002] The country's copper concentrates are gradually tending towards low-coarse hybridization. As the content of impurity elements such as elemental sulfur, fluorine, chlorine, lead, zinc, etc. in the flue gas produced by the smelting of copper raw materials becomes higher and higher, the flue gas composition and phase become more and more complex. During the copper smelting process, a large amount of volatile impurities and small dust particles in the raw materials are entrained into the flue gas.

[0003] The disclosure number of the existing public technology is: CN219111224U. A complex flue gas washing and purification device for copper smelting includes a purification liquid storage box, a sedimentation box, an air guide pipe, a liquid guide pipe, a liquid discharge frame, a filter element, and a knocking device: the sediment inside the sedimentation box enters the inside of the liquid discharge frame through the liquid guide pipe, and the liquid discharge frame is connected to the outside of the purification liquid storage box through a flange sealing sleeve, and an exhaust pipe is fixedly installed on the top of the sedimentation box; the filter element is fixedly installed inside the purification liquid storage box and extends upward to the outside of the purification liquid storage box; the utility model utilizes the collision between the knocking head and the knocking plate to continuously vibrate during filtering, so that the filter plate can shake off the filtered particles while filtering, avoiding the particles from sticking to the filter screen after filtration, and long-term contact causing clogging of the filter screen, while reducing the corrosion phenomenon and improving the service life of the filter screen.

[0004] However, the above patent still has certain disadvantages when used: the flue gas in the smelting process will have a high temperature. At this time, if the flue gas is directly discharged without cooling, it is easy to cause the overall temperature of the processing equipment to rise, resulting in damage to the internal structure. In addition, the above patent first introduces a large amount of flue gas into the air guide space and discharges it by increasing the pressure, which easily causes part of the flue gas to be unable to be discharged, causing the actual treated flue gas to be greatly reduced, and the heat contained in the flue gas cannot be utilized, which is not energy-saving and environmentally friendly. Moreover, the filter cleaning used for filtration requires the introduction of liquid after treatment to achieve cleaning operations. If the cleaning is not timely, it is easy to cause the filter to be blocked, affecting the subsequent flue gas treatment effect.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

In addition, the cleaning of the filter does not require additional power equipment to drive it, which can reduce the overall energy consumption and improve the overall energy-saving and environmental protection effect, and has the advantage of filter cleaning.

A water inlet pipe 14 and a drain pipe 19 are respectively installed on both sides of the surface of the treatment tube 1 between the upper sealing plate 20 and the lower sealing plate 18. The surface of the upper sealing plate 20 is connected to the jet ring 10 through a pipeline. The surface of the jet ring 10 is evenly installed. A number of groups of gas nozzles 11 are evenly installed around, the jet ring 10 is located in the middle of the inner surface of the treatment tube 1, a collecting hood 12 is fixedly installed in the middle of the top of the upper sealing plate 20, and a guide plate 21 is installed obliquely on one side of the inner part of the collecting hood 12.

The brush 6 is provided to clean the surface of the filter screen 3.

[0033] In one embodiment, an air inlet 16 is provided in the middle of the bottom of the treatment tube 1. The air inlet 16 is connected to the lower sealing plate 18 through a pipeline. The air inlet 16 is provided to introduce the fume generated during the production of metallic copper for treatment.

[0034] In one embodiment, air outlets 2 are symmetrically installed on both sides of the top of the treatment tube 1. The air outlets 2 are provided to guide the flue gas after cooling and removal of particulate impurities, so as to facilitate the processing operation of subsequent equipment.

[0035] In one embodiment, the size of the spray ring 8 is smaller than that of the collecting hood 12. The size is set to ensure that the liquid sprayed from the spray ring 8 can be smoothly collected by the collecting hood 12 after acting on the flue gas, thereby avoiding waste and pollution.

[0038] In one embodiment, a driving groove 13 is provided at the bottom end of the collecting hood 12 for driving the blades 17 to rotate. The driving groove 13 is provided to allow the liquid used for flushing the flue gas to impact the driving blades 17 along a certain trajectory and thereby drive the driving shaft 4 to rotate, so that it can drive the brush 6 to clean the surface of the filter 3, thereby preventing dust in the flue gas from adhering to the filter 3 and causing the holes of the filter 3 to be blocked, thereby affecting the overall filtering effect.

[0039] Working principle: In actual use, personnel can connect the high-temperature flue gas generated during the production of the metal copper that needs to be processed to the air inlet 16 through a pipe. At this time, the high-temperature flue gas will enter the lower sealing plate 18 through it, and be diverted into multiple diversion pipes 15 between the lower sealing plate 18 and the upper sealing plate 20, and then the high-temperature flue gas will be transported through the diversion pipe 15. At the same time, liquid can be introduced into the outside of the diversion pipe 15. At this time, the high-temperature flue gas can transfer heat to the inside of the liquid through the pipe wall of the diversion pipe 15, which can realize the cooling of the high-temperature flue gas on the one hand and the heating of the liquid on the other hand. The liquid after subsequent heating can be used for heating the factory or drinking, so as to realize the effective utilization of heat, improve the overall energy-saving and environmental protection effect of the device, and facilitate better use. Then the flue gas diverted through the diversion pipe 15 can be gathered again and sprayed through the gas nozzles 11 on the surface of the jet rings 10 on both sides. At this time, the ejected flue gas can contact the liquid generated by the falling flushing nozzle 9. At this time, the flue gas Solid particles in the air can be adsorbed, and secondary cooling of the flue gas can be achieved to prevent high-temperature flue gas from causing burns to personnel. Then the falling liquid will gather inside the collection hood 12. Due to the inclined structure on one side of the collection hood 12, the falling liquid can flow along the surface of the side with a larger inclination. At this time, the flowing liquid can impact the driving blades 17 at the bottom and drive the driving shaft 4 to rotate. At this time, the rotation of the driving shaft 4 can drive the cleaning plates 5 on both sides of the filter 3 to rotate, so as to achieve the cleaning operation of the surface of the filter 3, prevent the particles in the flue gas from adhering to the holes and causing blockage, and improve the filtering quality of the flue gas. The cleaning of the filter 3 does not require additional power equipment to drive, which can reduce the overall energy consumption and improve the overall energy-saving and environmental protection effect. Then the secondary cooled flue gas is filtered through the filter 3 and finally discharged from the outlet 2 into another processing equipment for secondary treatment, thereby improving the overall treatment quality of the flue gas and reducing subsequent pollution. The device as a whole has the advantages of smoke cooling, heat utilization and filter cleaning.
