Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metallurgical dust removal equipment, in particular to a dust removal device for copper smelting. BACKGROUND

[0002] In the process of small-scale copper smelting production, a large amount of dust-containing flue gas is continuously generated at the mouth of a small copper smelting reduction furnace. Such flue gas not only carries high-concentration heavy metal particulate matters (such as copper oxide, arsenic, lead compounds, etc.), unburned ore powder and various volatile metal oxides, but also is accompanied by extremely high temperature, usually up to 800-1300℃.

[0003] However, the treatment of flue gas under high temperature faces double technical bottlenecks. First, the core filter material (such as filter bag) or internal components of the electric field of conventional bag-type dust collectors, electrostatic precipitators and other mainstream dry dust removal equipment cannot withstand such extreme heat load for a long time. Direct contact with high-temperature flue gas can easily cause rapid ablation and embrittlement failure of the filter bag, or cause electrode deformation and short circuit, greatly reducing the service life of the equipment. Second, even if the equipment material is strengthened, most high-efficiency dust removal technologies (especially filter materials relying on physical interception) have strict upper limit on the applicable range of flue gas temperature (usually below 260°C), and will directly lose their designed dust removal efficiency if the temperature exceeds the limit. Therefore, the high-temperature flue gas must undergo a forced cooling process before entering the high-efficiency dust removal unit.

[0004] However, the dust removal device in the related art mainly relies on water spraying evaporation cooling or the introduction of a large amount of low-temperature air for dilution and heat exchange cooling. The pure water spraying cooling has significant drawbacks: the water quantity needs to be accurately controlled in the cooling section to prevent the flue gas from being excessively saturated and causing dew condensation. The combination of dew and acidic substances (such as sulfur dioxide) in the flue gas can form a corrosive solution, which can accelerate the corrosion of the inner wall of the subsequent pipeline and equipment. Insufficient water evaporation can cause the humidity of the flue gas to increase sharply, and the wet dust can adhere to the surface of the subsequent dry dust collector (such as the filter bag), quickly forming a hardening blockage, increasing the system resistance and greatly reducing the dust removal effect. On the other hand, the introduction of cold air can reduce the temperature, but it can also cause the overall flue gas volume to expand, forcing the specifications of the subsequent equipment such as the fan, pipeline and dust collector to increase, resulting in high operating energy consumption.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0024] Referring to Figure 1 In the copper smelting process, the main smelting is carried out by a copper smelting reduction furnace 100 (only part of the structure is shown in the figure), the copper smelting reduction furnace 100 makes the copper metal, oxide or sulfide in the slag volatilize by blowing a mixture of air and pulverized coal into the liquid slag, and a large amount of dust-containing flue gas is continuously generated at the furnace mouth. In order to remove harmful substances in the high-temperature dust-containing flue gas and avoid low subsequent dust removal efficiency, the high-temperature flue gas must pass through a forced cooling process before entering the high-efficiency dust removal unit. Based on this, the inventor proposes a dust removal device for copper smelting.

[0025] Referring to Figures 2 to 4 The dust removal device 200 can include a water-cooled box 10, a cooling supply assembly 20, a heat dissipation roller assembly 30, a flue gas input pipeline 40, and a flue gas output pipeline 50. The water-cooled box 10 has a sealed containing cavity 11, and the opposite end faces of the water-cooled box 10 are connected to the flue gas input pipeline 40 and the flue gas output pipeline 50, respectively. The cooling supply assembly 20 is in communication with the containing cavity 11 through a pipeline to provide a circulating cooling medium in the containing cavity 11. The heat dissipation roller assembly 30 is rotationally connected to the water-cooled box 10 in the containing cavity 11.

[0026] The heat dissipation roller assembly 30 includes a first disc 31, a second disc 32, and heat dissipation sub-pipes 33 connected to the first disc 31 and the second disc 32, respectively. A plurality of heat dissipation sub-pipes 33 are distributed between the first disc 31 and the second disc 32 along the circumference. The first disc 31 and the second disc 32 are respectively attached to the opposite end faces of the containing cavity 11 to form a sealed cooling cavity between the first disc 31 and the second disc 32. When the heat dissipation roller assembly 30 rotates, the two ends of the plurality of heat dissipation sub-pipes 33 alternately communicate with the flue gas input pipeline 40 and the flue gas output pipeline 50.

[0027] It should be noted that in order to improve the integration of the dust removal device 200, to facilitate the transfer of the dust removal device 200 and to protect the internal structure of the dust removal device 200, the dust removal device 200 can also be provided with a support shell 60, which can be provided with a certain height and completely wrap the water cooling box 10, the cooling supply assembly 20 and the heat dissipation roller assembly 30. The flue gas input pipe 40 and the flue gas output pipe 50 respectively pass out of the support shell 60. The end of the flue gas output pipe 50 can be connected to the equipment of the next process, such as further treatment of dust or toxic gas.

[0028] It should also be noted that the pipe diameters of the plurality of heat dissipation sub-pipes 33 are the same, and the two ends of the heat dissipation sub-pipes 33 respectively penetrate the first disc 31 and the second disc 32. In order to ensure that each heat dissipation sub-pipe 33 can accurately communicate with the flue gas input pipe 40 and the flue gas output pipe 50 and has the same communication time with the flue gas input pipe 40 and the flue gas output pipe 50, the plurality of heat dissipation sub-pipes 33 can be equidistantly arranged on the same circumference. The number of heat dissipation sub-pipes 33 can be three, four or six, which can be selected according to actual needs.

[0029] In the present embodiment, the dust removal device 200 is connected to the heat dissipation roller assembly 30 by rotating in the containing cavity 11 of the water cooling box 10. The heat dissipation roller assembly 30 includes the first disc 31, the second disc 32 and the heat dissipation sub-pipe 33 arranged between the first disc 31 and the second disc 32. The first disc 31 and the second disc 32 are respectively sealingly attached to the inner walls of the opposite sides of the containing cavity 11 to form a closed cooling cavity between the first disc 31 and the second disc 32. The cooling cavity is maintained by the connection between the cooling supply assembly 20 and the water cooling box 10 to maintain the directional circulation of the cooling medium in the cooling cavity. On the one hand, the non-contact cooling between the cooling medium and the dust-containing flue gas can avoid the generation of corrosive solution and hardened block, reduce the resistance in the conveying pipe and improve the dust removal effect in the subsequent process. On the other hand, during the cooling process, the heat dissipation roller assembly 30 rotates, so that the two ends of the plurality of heat dissipation sub-pipes 33 alternately communicate with the flue gas input pipe 40 and the flue gas output pipe 50. In this way, the heat dissipation roller assembly 30 disturbs the cooling medium during rotation, and the heat dissipation sub-pipe 33 alternately communicates with the flue gas input and output pipes, which improves the cooling effect, effectively controls the upper limit temperature of the flue gas and avoids the loss of dust removal efficiency of the equipment in the subsequent process.

[0031] Further, the circumferential edge of the first disc 31 is provided with an annular gear ring 311, the other output shaft of the double-shaft motor 12 is connected with an intermittent gear 14, when the intermittent gear 14 rotates, the intermittent gear 14 is intermittently engaged with the annular gear ring 311, so that each heat dissipation sub-pipe 33 is periodically and alternately connected with the flue gas input pipeline 40 and the flue gas output pipeline 50, specifically, a first pulley 121 is arranged at the other output shaft end of the double-shaft motor 12, the intermittent gear 14 is rotatably connected outside the outer wall of the water-cooled box 10, the intermittent gear 14 is connected with a second pulley 123 through a connecting rod 124, and the first pulley 121 and the second pulley 123 are connected through a conveying belt 122, so that when the double-shaft motor 12 operates, the vane fan 13 and the heat dissipation roller assembly 30 are driven to rotate synchronously, which on the one hand reduces the occupied space of the device, and on the other hand, the rotating direction of the vane fan 13 is opposite to the rotating direction of the heat dissipation roller assembly 30, so that the heat dissipation roller assembly 30 collides with the cooling medium in the cooling cavity, thereby further improving the heat dissipation effect of the high-temperature flue gas.

[0034] Specifically, the support 332 can be fixed with the inner side wall of the pipe body 331, and the support 332 can be provided with a through hole at the position of the axis in the pipe body 331, and the transmission rod 333 can be in sliding connection with the support 332 through the through hole; the spoiler rings 335 arranged on the transmission rod 333 are in abutment with the inner side wall of the pipe body 331, so that the transmission rod 333 is limited in the radial direction and can only move in the radial direction, and when the transmission rod 333 moves in the radial direction, the spoiler rings 335 slide along the axis on the inner side wall of the pipe body 331, and the spoiler rings 335 can scrape the wall of the pipe body 331, so that the dust deposited on the inner wall of the pipe body 331 can be effectively removed during the cooling process, and the heat dissipation sub-pipe 33 is prevented from being blocked.

[0035] Further, the elastic member 334 can be a high-temperature-resistant spring structure, the plurality of protrusions 1121 arranged at intervals in the annular groove 112 can have an interval distance selected according to actual needs, and an arc surface (not shown in the figure) can be arranged on one side of the protrusion 1121, the arc surface can be arranged in a convex or concave manner, and is mainly used for guiding the transmission rod 333 and reducing the resistance of the transmission rod 333 sliding through the protrusion 1121, so that one end of the transmission rod 333 slides from the bottom of the protrusion 1121 to the top of the protrusion 1121, and the end surface of the protrusion 1121 away from the arc surface can be arranged as a vertical surface (not shown in the figure), so that when the transmission rod 333 slides to the top end of the protrusion 1121, the transmission rod 333 is instantly pulled from the top end to the bottom end of the protrusion 1121 by the spring, so as to change the uneven speed of the spoiler rings 335 reciprocating along the inner wall of the pipe body 331 and improve the dust removal efficiency of the dust deposited on the inner wall of the pipe body 331.

[0036] In some embodiments, please refer to Figure 9The cooling supply assembly 20 includes a coolant circulation box 21 and a water pump 22.
