Description

Technical Field

[0001] The invention relates to the technical field of sintering smoke capture, and in particular to a split-type high-efficiency smoke capture device and method for unloading a ring cooler. Background Art

[0002] The sintering production process is that the raw materials such as concentrate powder, limestone, lime and fuels such as crushed coke and anthracite are mixed in a certain ratio, and then distributed at the head of the sintering machine. After ignition, the powder is sintered into blocks and naturally broken by its own gravity at the tail of the sintering machine. Then it is crushed by a single roller crusher, screened by a chute, and enters a ring cooler for cooling. Finally, the cooled sintered ore is screened for whole particles and sent to the sintering finished product bin by a belt to be used in the blast furnace ironmaking method.

[0003] When the cooling machine trolley turns downward to dump materials, a large amount of intermittent smoke and dust is generated, with a dust concentration of 5~15 g / m 3 The existing unloading hood has many problems. The hood structure is a square hood. There is a huge gap between the front and rear ends of the hood and the sintering machine trolley and platform, which causes a large amount of wild wind to mix into the unloading hood. The air volume of the dust removal system has to be increased to ensure the efficiency of collecting dust, resulting in great energy consumption. The overall top suction method is adopted, and the three suction hoods are far away from the dust source, which has low efficiency in collecting dust. The dust stays in the unloading hood for a long time and is easy to emerge from all sides of the hood. The unloading hood and the annular cooler platform are not tightly sealed as a whole, and some dust escapes from the gaps on both sides of the unloading hood and the annular cooler platform, which greatly pollutes the workplace environment.

[0004] Therefore, it is necessary to transform the large hood of the annular cooler unloading according to the production characteristics of the annular cooler unloading place, so as to reduce the air volume of the dust removal system, improve the smoke collection efficiency and prevent the smoke from escaping. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that the unloading hood and the annular cooler platform are not tightly sealed as a whole, and some smoke and dust escape from the gaps on both sides of the unloading hood and the annular cooler platform, which greatly pollutes the workplace environment.

When the sintered materials are transported to the top of an unloading box, the annular cooler trolleys unload the materials; then, dust is captured, the sintered materials enter the unloading box, and a plurality of air suction ports on the top of the split-type unloading hood are connected to dust removal pipes. The airflow direction of the bottom flue gas is optimized through guide plates, the suction effect of the air suction ports is enhanced, and at the same time, the particles collide with the guide plates with the inertia of the airflow, thereby removing part of the smoke dust; in the material receiving step: the sintered materials enter the unloading box; When the sintered material falls, the driving unit drives the first rotating shaft to rotate, and drives the first receiving plate to rotate, so as to preliminarily receive the fallen sintered material. Then, as the first rotating shaft rotates, the sintered material falls downward onto the second receiving plate, and the elastic force of the first spring is used to reduce the impact force of the falling sintered material. Finally, auxiliary dust suction is performed. When the sintered material falls, the smoke and dust generated rises upward. At this time, the driving unit drives the two full gears to rotate in the sealed chamber, and then a part of the rising smoke and dust is extracted through the first through hole through the first air supply channel, and then it is ejected through the second through hole through the second air supply channel, and then it is extracted through the air suction port above the guide plate.

[0017] Compared with the prior art, the present invention provides a split-type high-efficiency fume capture device and method for annular cooler unloading, which has the following beneficial effects:

[0018] The present invention is a split type high-efficiency fume capture device and method for sintering machine ring cooling unloading, comprising: a split type unloading hood, T-shaped sealing grooves are arranged on both sides of the lower end of the split type unloading hood, guide plates are arranged on both sides of the bottom of the split type unloading hood, and three specific air suction ports are arranged in the middle of the upper part of the split type unloading hood, which are connected to the dust removal pipeline, and the T-shaped sealing grooves are arranged to prevent smoke and dust from escaping by changing the structure of the split type unloading hood.

[0019] The structure of the unloading hood of the annular cooler is optimized. The convex structure can be closer to the annular cooler trolley, reduce the mixing of wild wind, and reduce the air volume of the dust removal system. At the same time, the air intake is closer to the dust generating point, which effectively improves the dust capture efficiency.

[0020] A number of guide plates are arranged at the bottom of the split-type unloading hood, which can effectively enhance the suction effect of the suction hood. At the same time, the particles hit the guide plates with the inertia of the air flow, which can remove part of the smoke and dust to achieve a pre-dust removal effect.

[0021] The first receiving plate and the second receiving plate play a buffering role when the sintered material is unloaded, reducing the impact force of the falling sintered material colliding with the sintered material at the bottom of the unloading box, thereby further preventing dust.

[0022] When the sintering material falls, the smoke and dust generated rises upward. At this time, a part of the rising smoke and dust can be extracted while the sintering material is being received, and then sprayed out through the second through hole through the second air supply channel, and then extracted through the air suction port above the guide plate, thereby further preventing dust.

[0041] A split-type high-efficiency flue gas capture method for annular cooler unloading comprises the following steps: firstly, unloading is performed, high-temperature sintered materials are collected through annular coolers, and the sintered materials are transported through annular cooler trolleys 6. When the sintered materials are transported to the top of an unloading box 1, the annular cooler trolleys 6 are used for unloading; then, dust is captured, the sintered materials enter the unloading box 1, and a plurality of air suction ports on the top of the split-type unloading hood 3 are connected to the dust removal pipeline, and the air flow direction of the bottom flue gas is optimized through the guide plate 301, the suction effect of the air suction port is enhanced, and at the same time, the particulate matter impacts the guide plate 301 with the inertia of the air flow, thereby removing a part of the smoke dust; in the material receiving step: when the sintered materials enter the unloading box 1, the driving unit drives the first The rotating shaft 7 rotates, driving the first receiving plate 701 to rotate, thereby preliminarily receiving the fallen sintering material, and then with the rotation of the first rotating shaft 7, the sintering material falls downward onto the second receiving plate 101, and the elastic force of the first spring 102 reduces the impact force of the sintering material falling; finally, auxiliary dust collection is performed, when the sintering material falls, the smoke and dust generated rises upward, and at this time, the two full gears 801 are driven by the driving unit to rotate in the sealing chamber 8, and then a part of the rising smoke and dust is extracted through the first air delivery channel 804 through the first through hole 802, and then ejected through the second air delivery channel 805 through the second through hole 806, and then extracted through the air suction port above the guide plate 301;

[0042] It should be noted that, in the present embodiment, the driving part is realized by a motor 4 and a plurality of pulley mechanisms, and the pulley mechanisms are composed of two pulley bodies and a track. Since it is a relatively commonly used structural design, it will not be described in detail here. The reducer 5 disclosed in the present embodiment mainly plays a role in changing the speed ratio, thereby increasing the speed of the gear pump composed of two full gears 801 and the sealed chamber 8. Since the sintered material needs to be discharged slowly, the first receiving plate 701 rotates slowly. When the sintered material is unloaded, the first receiving plate 701 and the second receiving plate 101 have a buffering effect, which reduces the impact force of the falling sintered material colliding with the sintered material at the bottom of the discharge box 1, thereby further preventing dust.

[0043] The split unloading cover of the present invention is in the shape of a convex character, the upper protruding part covers the ring cooler trolley, and the two side parts cover the ring cooler platforms 2 on both sides of the trolley. The overall air volume of the system is 80,000 to 200,000 m 3 / h, the air volume of the suction hood at the top of the middle of the hood is 40,000 to 120,000 m 3 / h, the air volume of each suction hood on both sides is 2~8m 3 / h, when the annular cooler trolley 6 is unloading, the high-temperature sintered material falls, causing smoke and dust to rise from the unloading chute and escape outward through the annular cooler platform 2 and the trolley part. This structure can be better attached to the annular cooler trolley 6, and the air suction hood is closer to the dust generating point, reducing the area of ​​the front and rear openings of the hood, effectively reducing the mixing of wild wind, improving the capture efficiency, and reducing the system air volume.

[0044] Among them, T-shaped sealing grooves 201 are provided on both sides of the bottom of the split unloading hood body, which are used to connect with the ring cooler platform 2 to prevent smoke and dust from escaping from the bottom of the hood body and both sides of the ring cooler platform 2.

[0045] Among them, a plurality of guide plates 301 are provided at the lower part of the split unloading hood, distributed on both sides of the suction hood. Since the suction hood is arranged in the middle of the hood body, the suction effect on the front and rear ends of the airflow in the hood body is relatively weak, especially the heights of the two sides of the lower part are relatively low, and the suction effect on the airflow at both ends is even worse. Therefore, the guide plates 301 are arranged to optimize the flow direction of the bottom flue gas airflow. The angle of the guide plates 301 is 20 to 60 degrees in the horizontal direction, preferably 30 degrees, which can effectively enhance the suction effect of the suction hood. At the same time, the particulate matter hits the guide plates 301 with the inertia of the airflow, which can remove part of the smoke and dust, thereby achieving a pre-dust removal effect.

[0046] The advantages of the present invention are as follows:

[0047] The present invention is a split type high-efficiency fume capture device and method for sintering machine ring cooling unloading, comprising: a split type unloading hood 3, two sides of the lower end of the split type unloading hood 3 are provided with T-shaped sealing grooves 201, two sides of the bottom of the split type unloading hood 3 are provided with guide plates 301, and three specific air suction ports are provided in the middle of the upper part of the split type unloading hood 3, which are connected to the dust removal pipeline, and the T-shaped sealing grooves 201 are provided to prevent the escape of smoke and dust by changing the structure of the split type unloading hood 3.

[0048] The structure of the unloading hood of the annular cooler is optimized. The convex structure can be closer to the annular cooler trolley 6, reduce the mixing of wild wind, reduce the air volume of the dust removal system, and at the same time, the air intake is closer to the dust generating point, effectively improving the dust collection efficiency.

[0049] A plurality of guide plates 301 are provided at the lower part of the split type unloading hood 3, which can effectively enhance the suction effect of the suction hood. At the same time, particles collide with the guide plates 301 with the inertia of the air flow, which can remove part of the smoke and dust to achieve a pre-dust removal effect.

When the sintered materials are transported to the top of the unloading box (1), the ring cooler trolley (6) unloads the materials; S2: Dust capture, continuing from S1, the sintered material enters the discharge box (1), connects the multiple air suction ports on the top of the split-type discharge hood (3) to the dust removal pipeline, optimizes the flow direction of the flue gas at the bottom through the guide plate (301), strengthens the suction effect of the air suction port, and at the same time, the particles collide with the guide plate (301) with the inertia of the air flow, thereby removing part of the smoke dust; S3: receiving the material. When the sintered material enters the discharge box (1), the driving unit drives the first rotating shaft (7) to rotate, thereby driving the first receiving plate (701) to rotate, thereby initially receiving the falling sintered material. Then, as the first rotating shaft (7) rotates, the sintered material falls downward onto the second receiving plate (101), and the elastic force of the first spring (102) reduces the impact force of the falling sintered material. S4: Auxiliary dust suction. When the sintered material falls, the generated smoke and dust rises upward. At this time, the driving unit drives the two full gears (801) to rotate in the sealed chamber (8), and then a part of the rising smoke and dust is extracted through the first air supply channel (804) through the first through hole (802), and then ejected through the second air supply channel (805) through the second through hole (806), and then extracted through the air suction port above the guide plate (301).
