Description

Technical Field

[0001] The invention belongs to the technical field of flue gas treatment, in particular to a flue gas treatment device for red copper plate smelting production. Background Art

[0002] During the copper smelting process, the treatment of high-temperature flue gas is a key step in resource recovery and environmental protection. This flue gas not only contains a large amount of waste heat but also contains oxide particles of metals such as copper, zinc, and lead, making it highly valuable for recycling. Treatment of this flue gas begins by recovering the waste heat through heat exchangers and other equipment, converting the heat into usable energy (such as preheating combustion air or generating steam) for efficient energy utilization. Subsequently, the cooled flue gas is passed through an acid solution storage device, where acidic liquids such as dilute sulfuric acid or hydrochloric acid react with the metal oxides in the flue gas to form soluble salts, laying the foundation for subsequent metal recovery. In order to prevent solid particles in the flue gas from escaping with the airflow or contaminating subsequent treatment systems, existing processes usually set a filter layer at the flue gas inlet of the acid solution storage equipment, intending to retain the solid particles inside the equipment through interception.

[0003] However, as the treatment time increases, a large amount of solid particles will gradually accumulate on the surface of the filter layer, resulting in a decrease in air permeability. This not only increases the resistance to flue gas circulation, but also reduces the contact efficiency between the acid solution and the flue gas due to poor airflow, affecting the continuity of the treatment. On the other hand, even if the solid particles are intercepted by the filter layer, their distribution in the equipment is relatively dispersed. Some particles will adhere to the surface of the filter layer, some will settle to the bottom of the equipment with the airflow, and some will be suspended in the acid solution, making it difficult to collect them in a centralized manner after shutdown, increasing the difficulty of subsequent solid particle separation and purification.

[0004] To this end, the present invention provides a flue gas treatment device for red copper plate smelting production. Summary of the Invention

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figures 1 to 9 As shown, the fume treatment device for red copper plate smelting production described in the present invention includes a gas transmission mechanism, a liquid transmission mechanism, a filtering mechanism, a collecting mechanism and a control mechanism.

[0020] The infusion mechanism includes a treatment box 1, a liquid inlet pipe 4 and a liquid discharge pipe 26. The liquid inlet pipe 4 and the liquid discharge pipe 26 are both fixedly installed on the outer wall of the treatment box 1. In this embodiment, the liquid stored in the treatment box 1 is a dilute sulfuric acid solution, wherein the liquid inlet pipe 4 is connected to the external dilute sulfuric acid solution storage chamber for injecting dilute sulfuric acid solution into the treatment box 1, and the liquid discharge pipe 26 is used to discharge the liquid in the treatment box 1 after the reaction.

[0021] The dilute sulfuric acid solution reacts with the alkaline metal oxides in the flue gas (the flue gas after waste heat recovery, i.e., the flue gas after cooling) to generate soluble salts (such as copper sulfate, zinc sulfate or copper chloride, zinc chloride, etc.). Some reactions will also directly generate elemental metal particles (such as cuprous oxide reacting with dilute sulfuric acid to generate elemental copper). At the same time, the lead oxide reacts with dilute sulfuric acid to generate slightly soluble lead sulfate precipitate, forming recyclable solid particles.

[0022] The gas delivery mechanism includes a gas delivery pipe 5 and an exhaust pump 2. The gas delivery pipe 5 is used to deliver cooled smelting flue gas into the processing box 1. One end of the gas delivery pipe 5 is connected to the exhaust end of the flue gas waste heat recovery equipment, thereby injecting flue gas into the processing box 1.

[0023] The input end of the exhaust pump 2 extends to the inner cavity of the treatment box 1 and is located above the liquid level in the inner cavity of the treatment box 1 in real time. After the flue gas is injected, it reacts with the acidic solution in the treatment box 1 and the remaining gas floats up and is then discharged through the exhaust pump 2, thus entering the next flue gas treatment process.

[0024] In order to increase the reaction time of the flue gas and the acid solution, the exhaust pump 2 is turned on intermittently to extend the contact reaction time of the flue gas and the acid solution.

[0025] The filtering mechanism includes a support frame 27 and a filter cartridge 18 arranged on the outer wall of the support frame 27. The support frame 27 can be detachably installed on the inner wall of the treatment box 1. The filter cartridge 18 is made of elastic material, wherein one end of the drain pipe 26 extends to the inner cavity of the support frame 27. When the drain pipe 26 discharges liquid, the solid particles in the solution are filtered through the filter cartridge 18. By evenly opening a plurality of through holes on the outer wall of the drain pipe 26, the filter cartridge 18 can be kept as evenly stressed as possible during drainage.

[0026] The collecting mechanism includes a collecting cylinder 13 , a drainage plate 14 and a scraping ring 25 slidably arranged on the outer wall of the filter cylinder 18 . The outer wall of the scraping ring 25 is in close contact with the outer wall of the filter cylinder 18 .

[0027] The axis of the collecting cylinder 13 coincides with the axis of the filter cylinder 18 , and the drainage plate 14 is fixedly installed on the outer wall of the collecting cylinder 13 . The collecting cylinder 13 is slid until the collecting cylinder 13 is sleeved on the outside of the filter cylinder 18 . During this process, the liquid in the inner cavity of the collecting cylinder 13 is discharged through the drainage plate 14 .

[0028] As the filter cartridge 18 slides, the contact position between the scraper ring 25 and the filter cartridge 18 is located inside the collecting cartridge 13. At this time, the collecting cartridge 13 and the scraper ring 25 slide synchronously in opposite directions. The scraper ring 25 scrapes off the solid particles adsorbed on the surface of the filter cartridge 18, and the solid particles then fall off into the inner cavity of the collecting cartridge 13, thereby realizing the collection of the solid particles.

[0029] The control mechanism controls the movement of the collection tube 13 through the pressure difference between the inside and outside of the processing box 1. As the flue gas is input through the gas pipe 5, a dynamic pressure difference is generated between the inside and outside of the processing box 1 during the process of exhaust and shutdown of the exhaust pump 2. The control mechanism converts this part of kinetic energy and uses it to control the movement of the collection tube 13.

[0030] The collecting cylinder 13 reciprocates, and the scraping ring 25 scrapes the solid particles on the outer wall of the filter cylinder 18 into the inner cavity of the collecting cylinder 13, thereby realizing automatic collection of solid particles during flue gas treatment. Compared with the method of retaining solid particles in the treatment box 1 in the form of filtration, the efficiency of subsequent concentrated collection of solid particles can be improved. At the same time, when flue gas is injected into the gas pipe 5, the movement of liquid inside the treatment box 1 is disturbed, thereby facilitating the filter cylinder 18 to adsorb solid particles, further improving the collection efficiency of solid particles. In addition, collecting solid particles in the treatment box 1 can effectively extend the service life of the filter cylinder 18.

[0031] A drainage pump 7 is fixedly installed on the outer wall of the processing box 1, and the input end of the drainage pump 7 is connected to the drainage pipe 26. The drainage pump 7 extracts the solution after the reaction inside the processing box 1 through the drainage pipe 26 and sends it to the next process (such as replacement reaction).

[0032] An induction cylinder 3 is fixedly mounted on the upper end surface of the processing box 1. The inner cavity of the induction cylinder 3 is communicated with the inner cavity of the processing box 1. A through hole communicated with the induction cylinder 3 is opened at the upper end of the processing box 1. An induction plug 11 is elastically mounted on the inner wall of the induction cylinder 3. The outer wall of the induction plug 11 is sealed and fitted with the inner wall of the induction cylinder 3. A spring is provided on the outer wall of the induction plug 11. The other end of the spring is fixedly connected to the inner wall of the induction cylinder 3. When the air pressure in the inner cavity of the processing box 1 increases (the exhaust pump 2 stops working), the induction plug 11 slides up. When the air pressure in the inner cavity of the processing box 1 decreases (the exhaust pump 2 is exhausted), the induction plug 11 is pushed down by the elastic force of the spring.

[0033] The outer wall of the processing box 1 is detachably mounted with a mounting plate 10, and the collecting cylinder 13 is located on one side of the mounting plate 10. The mounting plate 10 is connected to the side wall of the processing box 1 by bolts, and a corrosion-resistant sealing gasket is provided at the connection position.

[0034] The control mechanism includes a control cylinder 9 , a control plug 24 , a connecting rod 22 , a support ring 15 and a balance pipe 8 .

[0035] The control cylinder 9 is fixedly mounted on the outer wall of the mounting plate 10 , and one end of the control cylinder 9 is connected to the inner cavity of the sensing cylinder 3 . A conduit is provided on the outer wall of the control cylinder 9 , and the sensing cylinder 3 is connected to the control cylinder 9 via the conduit.

[0036] One end of the balance pipe 8 is connected to the inner cavity of the control cylinder 9, and the other end extends to the outer wall of the processing box 1. The balance pipe 8 is used to connect the chamber on one side of the control cylinder 9 with the outside air.

[0037] The outer wall of the control plug 24 slides in contact with the inner wall of the control tube 9, and the inner cavity of the control tube 9 is divided into two chambers by the control plug 24, one of which is connected to the balance tube 8 and the other is connected to the sensing tube 3. When the sensing plug 11 slides, the control plug 24 is driven to slide synchronously.

[0038] The sensing tube 3 and the sensing plug 11 are provided to drive the control plug 24 to slide, thereby preventing acid gas from directly entering the inner cavity of the control tube 9 .

[0039] One end of the connecting rod 22 is fixedly connected to the outer wall of the control plug 24 , and the other end extends to the outer wall of the control cylinder 9 and is fixedly connected to the outer wall of the support ring 15 . During the sliding of the control plug 24 , the support ring 15 is driven to slide by the connecting rod 22 .

[0040] The collecting tube 13 is rotatably mounted inside the supporting ring 15 . When the connecting rod 22 drives the supporting ring 15 to slide, the collecting tube 13 moves synchronously, thereby controlling the movement of the collecting tube 13 by utilizing the pressure difference between the inside and outside of the processing box 1 .

[0041] As a preferred embodiment of the present invention, guide rods 16 are fixedly installed on the inner wall of the processing box 1. At least two guide rods 16 are provided. In this embodiment, three guide rods 16 are provided.

[0042] A connecting ring 17 is slidably installed on the outer wall of the guide rod 16, and the side wall of the connecting ring 17 is connected to the inner wall of the processing box 1 through an elastic member. The guide rod 16 is provided to provide a sliding trajectory for the connecting ring 17, wherein the elastic force controls the connecting ring 17 to have a real-time tendency to approach the inner wall of the processing box 1.

[0043] The scraping ring 25 is rotatably mounted on the inner wall of the connecting ring 17 , wherein the inner wall of the connecting ring 17 is provided with a torsion spring connected to the scraping ring 25 , and the connecting ring 17 provides support for the scraping ring 25 .

[0044] An elastic ring 28 is fixedly installed on the inner wall of the scraping ring 25, and a plug pin 19 for plugging with the elastic ring 28 is fixedly installed on the axial end of the collecting cylinder 13. As the collecting cylinder 13 slides, the plug pin 19 gradually plugs with the elastic ring 28. At this time, the collecting cylinder 13 is slid in the reverse direction, and the friction between the plug pin 19 and the elastic ring 28 is used to pull the scraping ring 25 to slide, thereby scraping the solid particles on the outer surface of the filter cylinder 18 into the inner cavity of the collecting cylinder 13, completing the fixing of the particles.

[0045] As the collecting cylinder 13 slides, the connecting ring 17 moves to the end of the guide rod 16, at which time the connecting ring 17 stops sliding until the plug pin 19 is pulled out from the inside of the elastic ring 28, and then the elastic member controls the connecting ring 17 to reset, thereby, in the process of the reciprocating motion of the collecting cylinder 13, the scraping ring 25 realizes the reciprocating scraping of the filter cylinder 18.

[0046] An elastic membrane 20 is fixedly installed on the inner wall of the collecting cylinder 13. The elastic membrane 20 is composed of multiple fan-shaped rubber sheets. When the collecting cylinder 13 and the filter cylinder 18 are plugged in, the elastic membrane 20 is lifted up by the support frame 27. After the collecting cylinder 13 and the filter cylinder 18 are separated, the elastic membrane 20 is reset to close the port of the collecting cylinder 13 to prevent solid particles inside the collecting cylinder 13 from escaping.

[0047] A control shaft 23 is fixedly mounted on the axial end of the collecting barrel 13 . A spiral groove 6 is formed on the radial outer wall of the control shaft 23 . Rotating the control shaft 23 drives the collecting barrel 13 to rotate synchronously.

[0048] A transmission sleeve 12 is fixedly mounted on the side wall of the mounting plate 10 , and the inner wall of the transmission sleeve 12 is slidably fitted with the outer wall of the control shaft 23 , thereby improving the sliding stability of the collecting tube 13 .

[0049] A guide ball 36 is fixedly installed on the inner wall of the transmission sleeve 12, and the outer wall of the guide ball 36 slides in contact with the inner wall of the spiral groove 6. During the reciprocating sliding of the collecting cylinder 13, the control shaft 23 and the collecting cylinder 13 are driven to rotate by the cooperation between the guide ball 36 and the spiral groove 6.

[0050] When the plug pin 19 is plugged into the elastic ring 28, the collecting cylinder 13 slides and rotates along the axis, thereby controlling the synchronous sliding and rotation of the scraping ring 25, achieving uniform coverage of the entire surface through a spiral trajectory, making the force more stable, and reducing damage to the elastic filter cylinder 18.

[0051] After the plug pin 19 is separated from the elastic ring 28 , the torsion spring between the scraper ring 25 and the connecting ring 17 controls the scraper ring 25 to rotate and reset, so that the plug pin 19 is plugged into the elastic ring 28 again.

[0052] As a preferred embodiment of the present invention, a support plate 35 is fixedly mounted on the inner wall of the support frame 27 , and the support frame 27 provides installation and support for the support plate 35 .

[0053] There are multiple support plates 35 , which are evenly distributed in a ring shape along the axis of the support frame 27 . The side walls of the support plates 35 are slidably mounted with force plates 34 , and the support plates 35 provide sliding tracks for the force plates 34 .

[0054] The outer wall of the force plate 34 is fixedly installed with a pressure plate 32 for pressing the inner wall of the filter cartridge 18. The pressure plate 32 is made of elastic material. When the scraping ring 25 scrapes the outer wall of the filter cartridge 18, the pressure plate 32 presses the filter cartridge 18 from the inside to the outside, so that the outer wall of the filter cartridge 18 and the scraping ring 25 fit tightly together, ensuring that impurities are fully scraped off, and reducing the mechanical wear of the filter cartridge 18 and the scraping ring 25 through elastic buffering, thereby extending the service life of both.

[0055] A control disk 29 is elastically mounted on the inner wall of the support frame 27 , a control board 31 is fixedly mounted on the side wall of the control disk 29 , and the control disk 29 is fixedly connected to the inner wall of the support frame 27 via a spring.

[0056] A transmission inclined groove 30 is provided on the outer wall of the control plate 31, and a transmission pin 33 is fixedly installed on the outer wall of the force plate 34. The outer wall of the transmission pin 33 slides in contact with the inner wall of the transmission inclined groove 30. The sliding control disk 29 drives the control plate 31 to slide. Through the sliding cooperation between the transmission inclined groove 30 and the transmission pin 33, the force plate 34 is controlled to slide, and then the top pressure plate 32 is controlled to press the inner wall of the filter cartridge 18.

[0057] An attraction disk 21 is elastically mounted on the inner wall of the collecting cylinder 13 . The attraction disk 21 repels the control disk 29 through magnetic force. In this embodiment, the attraction disk 21 and the control disk 29 are two NdFeB magnets that repel each other.

[0058] When the collecting cylinder 13 slides, the attraction plate 21 gradually approaches the control plate 29, and uses the mutually repelling magnetic force to push the control plate 29, thereby controlling the top pressure plate 32 to press the filter cylinder 18 from the inside to the outside. When the collecting cylinder 13 slides in the opposite direction, the attraction plate 21 is affected by the elastic force and remains in contact with the outer wall of the support frame 27. At this time, the top pressure plate 32 holds the filter cylinder 18, thereby improving the scraping quality of the scraping ring 25.

[0059] The above-mentioned front, back, left, right, up and down are all based on the Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
