Description

Technical Field

[0001] This utility model relates to the field of flue gas treatment technology, specifically to a mother-daughter surface cooling pipe assembly for controllable temperature operation of high-temperature flue gas after tin ore roasting. Background Technology

[0002] In the tin ore roasting process, high-temperature flue gas (usually reaching 400-600℃) needs to be rapidly cooled through a cooling system to meet the environmental protection requirements of subsequent dust removal, desulfurization, etc. Traditional surface cooling tube groups mostly use a single pipe for cooling. In the high temperature of summer, the single-pipe surface cooling needs to operate at full load, resulting in high energy consumption and limited cooling speed. In the low temperature of winter, the surface cooling tube is prone to excessive cooling, which can lead to excessively low flue gas temperature, affecting the stability of subsequent processes. The flue gas flow direction is fixed, and it is impossible to dynamically adjust the cooling path according to the season or operating conditions, resulting in energy waste or insufficient cooling.

[0003] To solve the above technical problems, it is necessary to design a mother-daughter surface cooling pipe assembly with controllable temperature operation for the high-temperature flue gas after tin ore roasting. Utility Model Content

[0004] The purpose of this invention is to provide a mother-daughter surface cooling pipe assembly for controllable temperature operation of high-temperature flue gas after tin ore roasting. It has the advantages of flexibly adjusting the two sets of pipes to cool the flue gas, achieving good flue gas treatment effect and low energy consumption. It solves the problems of existing surface cooling pipe assemblies that use a single pipe for cooling, resulting in poor flexibility, poor cooling effect, and high energy consumption.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mother-daughter surface cooling pipe assembly for controllable temperature operation of high-temperature flue gas after tin ore roasting, comprising a surface cooling pipe assembly body, a dust settling chamber provided on the left side of the surface cooling pipe assembly body, fixed pipes connected to the front and rear sides of the top of the dust settling chamber, a fan fixedly connected to the inner wall of the fixed pipes by a support plate, the top of the fixed pipes being connected to the surface cooling pipe assembly body by a pipe, a sealing mechanism being installed through the surface of the dust settling chamber, the sealing mechanism comprising a sealing plate, a connecting plate, a threaded rod and a motor, the top of the sealing plate contacting the top of the inner wall of the dust settling chamber.

[0006] Preferably, a mother cooling pipe assembly is provided through the rear side of the top of the cooling pipe assembly body, and a daughter cooling pipe assembly is provided through the front side of the top of the cooling pipe assembly body.

[0007] Preferably, one side of the motor is fixedly connected to the dust collection chamber, the motor shaft passes through the dust collection chamber and is fixedly connected to the threaded rod, the connecting plate is threaded onto the surface of the threaded rod, and one side of the connecting plate is fixedly connected to the sealing plate.

[0008] Preferably, the end of the threaded rod away from the motor shaft is movably connected to the inner wall of the dust settling chamber, and the threads on both sides of the threaded rod surface have opposite directions.

[0009] Preferably, a liquid pump is fixedly connected to the surface of the dust settling chamber. The inlet end of the liquid pump is connected to the bottom of the surface of the dust settling chamber through a pipe, and the outlet end of the liquid pump passes through the dust settling chamber through a pipe and is connected to a horizontal pipe. The bottom of the horizontal pipe is connected to an atomizing nozzle.

[0010] Preferably, the inner cavity of the dust settling chamber is provided with a filter frame, one side of which penetrates through the dust settling chamber and is movably connected to it. A pad is fixedly connected to the inner wall of the dust settling chamber, and one side of the pad is fixedly connected to the inner wall of the dust settling chamber.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting a sealing plate, connecting plate, threaded rod and motor, can independently control the opening and closing of the front and rear fixed pipes. It can discharge flue gas into the main or sub-main cooling pipe group in the cooling pipe group body as needed. In summer, due to the high outdoor temperature, all cooling pipes will be opened for rapid cooling. In winter, due to the low outdoor temperature, the rear fixed pipe will be closed and the flue gas will be discharged into the sub-main cooling pipe group. Through comprehensive consideration and adjustment of the cooling system and the natural temperature, the temperature of the cooling pipes is kept below 150℃, which greatly reduces energy consumption and saves economic costs.

[0013] 2. This utility model uses a liquid pump to extract liquid from the bottom of the dust suppression chamber, which is then atomized and sprayed out through a horizontal pipe and atomizing nozzle.

[0016] Please see Figures 1-4 A mother-daughter surface cooling pipe assembly for controllable temperature operation of high-temperature flue gas after tin ore roasting includes a surface cooling pipe assembly body 1. A dust settling chamber 2 is located on the left side of the surface cooling pipe assembly body 1. Fixed pipes 3 are connected to the front and rear sides of the top of the dust settling chamber 2. A fan 4 is fixedly connected to the inner wall of the fixed pipe 3 through a support plate. The top of the fixed pipe 3 is connected to the surface cooling pipe assembly body 1 through a pipe. A sealing mechanism 5 is installed through the surface of the dust settling chamber 2. The sealing mechanism 5 includes a sealing plate 50, a connecting plate 51, a threaded rod 52, and a motor 53. The top of the sealing plate 50 contacts the top of the inner wall of the dust settling chamber 2. 50, connecting plate 51, threaded rod 52, and motor 53 can independently control the opening and closing of the two fixed pipes 3 at the front and rear. As needed, the flue gas can be discharged into the mother cooling pipe group 6 or the daughter cooling pipe group 7 in the cooling pipe group body 1. In summer, due to the high outdoor temperature, all cooling pipes will be opened for rapid cooling. In winter, due to the low outdoor temperature, the rear fixed pipe 3 will be closed, and the flue gas will be discharged into the daughter cooling pipe group 7. Through comprehensive consideration and adjustment of the cooling system and the natural temperature, the temperature of the cooling pipes is kept below 150℃, which greatly reduces energy consumption and saves economic costs.

[0017] Please see Figures 1-2 A mother cooling pipe group 6 is installed through the rear side of the top of the cooling pipe group body 1, and a daughter cooling pipe group 7 is installed through the front side of the top of the cooling pipe group body 1. The mother cooling pipe group 6 has sixteen rows and nine columns, and the daughter cooling pipe group 7 has sixteen rows and three columns. By setting up the mother cooling pipe group 6 and the daughter cooling pipe group 7, the flue gas can be discharged into different cooling pipe groups for cooling treatment according to the needs in different seasons, so as to make reasonable use of the cooling pipe groups and reduce energy consumption.

[0018] Please see Figures 1-4 One side of the motor 53 is fixedly connected to the dust settling chamber 2. The rotating shaft of the motor 53 passes through the dust settling chamber 2 and is fixedly connected to the threaded rod 52. The connecting plate 51 is threaded onto the surface of the threaded rod 52. One side of the connecting plate 51 is fixedly connected to the sealing plate 50. When the motor 53 rotates, it can drive the threaded rod 52 to rotate, thereby causing the connecting plate 51 to move on the threaded rod 52, which in turn drives the sealing plate 50 to move, thus achieving precise control of the opening and closing of the fixed pipe 3.

[0019] Please see Figures 1-4The end of the threaded rod 52 away from the shaft of the motor 53 is movably connected to the inner wall of the dust settling chamber 2. The threads on both sides of the surface of the threaded rod 52 turn in opposite directions. The two connecting plates 51 connected to the threaded rod 52 can move in opposite directions at the same time, thereby driving the two sealing plates 50 to move closer or further away at the same time, realizing the opening or closing of the two fixed pipes 3. The two motors 53 are independently controlled and can independently control the opening and closing of the two fixed pipes 3.

[0020] Please see Figures 1-3 A liquid pump 8 is fixedly connected to the surface of the dust settling chamber 2. The inlet end of the liquid pump 8 is connected to the bottom of the surface of the dust settling chamber 2 through a pipe. The outlet end of the liquid pump 8 passes through the dust settling chamber 2 through a pipe and is connected to a horizontal pipe 9. The bottom of the horizontal pipe 9 is connected to an atomizing nozzle 10. The liquid pump 8 draws out the liquid from the bottom of the dust settling chamber 2, and sprays it out after atomization through the horizontal pipe 9 and the atomizing nozzle 10. This can increase the contact area between the flue gas and the liquid, improve the dust settling effect, reduce the dust content in the flue gas, and provide better conditions for subsequent cooling and environmental protection treatment.

[0021] Please see Figure 3 The dust settling chamber 2 is equipped with a filter frame 11. One side of the filter frame 11 passes through the dust settling chamber 2 and is movably connected to it. A pad 12 is fixedly connected to the inner wall of the dust settling chamber 2. One side of the pad 12 is fixedly connected to the inner wall of the dust settling chamber 2. The filter frame 11 can filter the liquid, remove residual dust and impurities, and facilitate the recycling of the dust settling liquid. The filter frame 11 is movably connected to the dust settling chamber 2, which is convenient for disassembly and cleaning, and ensures the filtration effect. The pad 12 serves to support the filter frame 11 and improve the stability of the structure.

[0022] Please see Figures 1-3 The bottom of the dust settling chamber 2 is connected to an electric liquid outlet valve 13, and the surface of the dust settling chamber 2 is connected to a liquid filling door 14 via a rotating shaft. The surface of the dust settling chamber 2 is also connected to an air inlet pipe 15. The electric liquid outlet valve 13 can easily control the discharge of liquid in the dust settling chamber 2, facilitating cleaning and maintenance. The liquid filling door 14 allows for the addition of liquid to the dust settling chamber 2, ensuring the amount of liquid required for dust settling and atomization treatment. The air inlet pipe 15 is the channel for high-temperature flue gas to enter the dust settling chamber 2, facilitating gas entry.

[0023] In use, high-temperature flue gas enters the dust settling chamber 2 through the inlet pipe 15. The liquid pump 8 is started to extract the liquid stored at the bottom of the dust settling chamber 2 and transport it through the pipeline to the horizontal pipe 9. The liquid is then atomized by the atomizing nozzle 10 at the bottom of the horizontal pipe 9 and sprayed out. The atomized liquid comes into full contact with the high-temperature flue gas entering the dust settling chamber 2, so that the dust particles in the flue gas are adsorbed by the liquid, thereby effectively reducing the dust content in the flue gas. The liquid after atomization and dust settling carries the dust impurities and falls into the bottom of the inner cavity of the dust settling chamber 2. The filter frame 11 further filters the liquid to remove the residual dust impurities and realize the recycling of the dust settling liquid. The liquid can be discharged by opening the electric liquid outlet valve 13, which makes it easy to replace the dust settling liquid. In summer, when outdoor temperatures are high, all surface cooling pipe assemblies need to be fully opened to quickly cool the high-temperature flue gas. The two motors 53 start simultaneously, driving their respective threaded rods 52 to rotate. The threaded rods 52 drive the two connecting plates 51 to move in opposite directions, which in turn moves the two sealing plates 50 away simultaneously. This ensures that the fixed pipes 3 on both sides of the top of the dust settling chamber 2 are open. Under the action of the fan 4, the high-temperature flue gas enters the surface cooling pipe assembly body 1 through the two fixed pipes 3 simultaneously, and flows into the main surface cooling pipe assembly 6 and the sub-surface cooling pipe assembly 7 for cooling, thus meeting the need for rapid cooling in hot weather. In winter, when outdoor temperatures are low, the rear fixed pipe 3 is closed, and the flue gas is concentrated and discharged into the sub-surface cooling pipe assembly 7 for cooling. Under the action of the fan 4, the high-temperature flue gas mainly enters the sub-surface cooling pipe assembly 7 through the front fixed pipe 3 for cooling, avoiding over-cooling of the surface cooling pipes. Simultaneously, through comprehensive consideration of the surface cooling system and natural temperature, the surface cooling pipe temperature is kept below 150℃, reducing energy consumption.

[0024] In summary, this mother-daughter surface cooling pipe assembly with controllable temperature operation for high-temperature flue gas after tin ore roasting, by setting up a sealing plate 50, a connecting plate 51, a threaded rod 52, and a motor 53, solves the problems of existing surface cooling pipe assemblies that use a single pipe for cooling, resulting in poor flexibility, poor cooling effect, and high energy consumption.
