In the absence of conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other.

[0035] Sintering dust ash is generated during the sintering production and transportation of sintered finished products. It has good comprehensive utilization characteristics as raw materials. Most of the sintering dust ash in the industry is returned to the sintering batching system for comprehensive utilization. The sintering process of the iron and steel plant produces 4500t to 5000t of dust ash per month. Before the transformation, the sintering dust ash was transported and comprehensively utilized through ash unloading and ash transportation, dust humidification, belt conveyor, centralized and closed ash unloading of dust ash, closed tank truck transportation, mixing of sintering dust ash with other raw materials, pre-batch, belt conveyor, sintering batching and other processes. Although it meets the requirements of environmental protection control, it has problems in actual operation such as long utilization process, many dust emission points, poor environmental quality in some links, and high operating costs.

[0036] In view of this, this application provides a sintering dust removal ash treatment system, please refer to Figure 1 , Figure 1 1 is a wireframe diagram of a sintering dust ash processing system in an embodiment of the present application. The sintering dust ash processing system 100 includes N conveying components 101 and a dust ash batching bin 102. Each conveying component 101 includes M dust collectors 1011 and a feeding pipe 1012. The dust collectors 1011 and the feeding pipes 1012 correspond to each other one by one, wherein N and M are positive integers greater than or equal to 1.

[0037] The dust collector 1011 has an ash bin 1013 for collecting sintering dust. The dust collector 1011 includes areas such as the head of the sintering machine 103, the sintering area of ​​the sintering machine 103, and the tail of the sintering machine 103. The exhaust gas output from each area of ​​the sintering machine 103 is sent to the dust collector 1011, and the dust collector 1011 filters the sintering dust in the exhaust gas and collects it in the ash bin 1013.

[0038] The inlet of the feed pipe 1012 is connected to the outlet of the ash bin 1013 of the corresponding dust collector 1011, and the outlet of the feed pipe 1012 is connected to the inlet of the dust ash batching bin 102, so as to transport the sintered dust in the ash bin 1013 to the dust ash batching bin 102. The sintered dust stored in the dust ash batching bin 102 is then sent to the sintering machine 103 for recycling.

[0039] The sintering dust ash treatment system 100 provided in the embodiment of the present application removes dust from the waste generated by the sintering device through the dust collector 1011 in the conveying component 101, and collects the sintering dust ash in the ash bin 1013, and sends the sintering dust ash in the ash bin 1013 to the dust ash batching bin 102 for storage through the feeding pipe 1012 for recycling by the sintering machine 103, thereby reducing the ash unloading and conveying, dust humidification, belt conveying, centralized and closed ash unloading of dust ash, and transportation by closed tank trucks required for processing sintering dust ash in the prior art, streamlining the processing process of sintering dust ash, and allowing the dust humidifier and dust closed conveying machinery to be shut down, thereby reducing the average daily operating time of each dust humidifier, dust closed conveyor, and belt, saving electricity, while reducing other operating and maintenance costs of related equipment and avoiding a long sintering dust ash recycling process.

[0040] On the other hand, the sintering dust ash treatment system 100 provided in the embodiment of the present application realizes the thorough clean transportation of sintering dust ash during the recycling process, avoids the phenomenon of dust emission during the transportation of dust ash vehicles that does not meet the government's environmental protection control requirements, and significantly improves the environmental quality of the sintering operation area; since the number of transport vehicles transporting dust ash by more than 150t per day is reduced, the cost of automobile transportation and mixing and adding transportation at the raw material yard is reduced, and at the same time, the operating cost of the corresponding transportation and batching equipment in the raw material yard is reduced, thereby reducing the overall operating cost.

[0041] like Figure 2 As shown, in some optional embodiments, the sintering dust ash treatment system 100 further includes: a main pipe 201 , and the outlet of the feed pipe 1012 is connected to the inlet of the dust ash batching bin 102 through the main pipe 201 .

[0042] The sintering dust ash output by multiple conveying components 101 is centrally delivered to the dust ash batching bin 102 through the main pipe 201, and the dust ash with different characteristics is simultaneously delivered to the dust ash batching bin 102, so that the sintering dust ash is mixed while entering the dust ash batching bin 102, which is beneficial to the stability of the sintering mixture composition under the sintering dust ash batching conditions.

[0043] In some optional embodiments, Figure 2As shown, the sintering dust ash processing system 100 also includes: a first level meter 206, which is arranged on the dust ash batching bin 102 and is used to detect the material level of the dust ash batching bin 102, and the ash bin 1013 of each dust collector 1011 in the M dust collectors 1011 has a second level meter 207, and the second level meter 207 is used to detect the material level of the ash bin 1013.

[0044] During the production process of the sintering machine 103, the material level information of the sintering dust ash batching bin 102 and the ash bin 1013 is monitored by the material level meter, so as to effectively control the recycling of the sintering dust ash.

[0045] In some optional embodiments, Figure 2 As shown, it also includes a gas source 202, N gas supply pipes 203, N air pumps 204, and a control mechanism 205; the gas source 202 stores gas, the N gas supply pipes 203 correspond one-to-one to the feed pipes 1012 of the N conveying components 101, and each of the N gas supply pipes 203 connects the inlet of the corresponding feed pipe 1012 to the gas source 202; the N air pumps 204 correspond one-to-one to the N gas supply pipes 203, and each of the N air pumps 204 is arranged on the corresponding gas supply pipe 203, and the gas supply pipe 203 is connected when the air pump 204 is turned on, and the gas supply pipe 203 is disconnected when the air pump 204 is turned off.

[0046] The control mechanism 205 is electrically connected to the first level meter 206 , the second level meter 207 and the air pump 204 respectively, and is used to receive the level information of the dust ash batching bin 102 sent by the first level meter 206 , and determine the adjustment of the dust ash addition amount according to the level information of the dust ash batching bin 102 .

[0047] The control mechanism 205 also receives the material level information of the ash bin 1013 of the dust collector 1011 sent by the second material level meter 207, and controls the number of air pumps 204 to be opened according to the material level information of the ash bin 1013 and the preset standard material level information.

[0048] When the control mechanism 205 controls the air pump 204 to open, the corresponding air supply pipe 203 is connected, and the high-pressure gas of the gas source 202 is injected into the feeding pipe through the air supply pipe 203, so as to blow the sintering dust ash entering the feeding pipe from the ash bin 1013 to the dust ash batching bin 102, and the sintering dust ash in the dust ash batching bin 102 is circulated to the sintering machine 103 for utilization. During the production process of the sintering machine 103, when the material level of the sintering dust ash in the dust ash batching bin 102 is too low, there will be a problem of insufficient supply to the sintering machine 103. At this time, it is necessary to increase the number of connected air supply channels to deliver more sintering dust ash to the dust ash batching bin 102. When the material level of the sintered dust ash in the dust ash batching bin 102 is too high, the number of the air supply channels that are open can be appropriately reduced to reduce the amount of sintered dust ash delivered to the dust ash batching bin 102 and avoid excessive accumulation of sintered dust ash in the dust ash batching bin 102.

[0049] The control mechanism 205 includes a first controller 2051 and a second controller 2052. The first controller 2051 is electrically connected to the first material level meter 206, and determines the adjustment of the dust ash addition amount according to the material level information of the dust ash batching bin 102. The outlet of the dust ash batching bin 102 is connected to the sintering machine through a pipeline, such as Figure 2 As shown, a discharge motor 1021 is provided on the outlet pipe of the dust ash batching bin 102, and the first controller 2051 is electrically connected to the discharge motor 1021. The first controller 2051 determines the adjustment of the dust ash addition amount according to the material level information of the dust ash batching bin 102, specifically including: adjusting the rotation speed of the discharge motor 1021 according to the material level information of the dust ash batching bin 102.

[0050] Specifically, when the material level of the dust ash batching bin 102 is too low, the first controller 2051 controls the speed of the discharge motor 1021 to decrease, so as to reduce the consumption of dust ash in the dust ash batching bin 102. When the material level of the dust ash batching bin 102 is too high, the first controller 2051 controls the speed of the discharge motor 1021 to increase, so as to increase the consumption of dust ash in the dust ash batching bin 102. From the operation form, just input different hourly discharge amounts in the control computer operation interface, and confirm it. The first controller 2051 automatically converts the hourly discharge amount into the corresponding speed of the discharge motor 1021 at the lower part of the dust ash batching bin 102 through the program, so as to achieve the adjustment of the material level in the dust ash batching bin 102.

[0051] The second controller 2052 is electrically connected to the second level meter 207 and the air pump 204 to receive the level information of the ash bin 1013 of the dust collector 1011 sent by the second level meter 207, and controls the number of times the air pump 204 is opened according to the level information of the ash bin 1013 and the preset standard level information.

[0052] It can be understood that the first controller 2051 is also electrically connected to the second controller 2052. When the dust ash in the dust ash batching bin 102 is consumed more and the material level of the dust ash batching bin 102 is too low, the first controller 2051 can send a signal to the second controller 2052, and the second controller 2052 controls the number of air pumps to increase so as to increase the amount of dust ash in the dust ash batching bin 102.

[0053] When the dust ash in the dust ash batching bin 102 is consumed less and the material level in the dust ash batching bin 102 is too high, the first controller 2051 can also send a signal to the second controller 2052, and the second controller 2052 controls the number of air pumps to reduce to reduce the amount of dust ash in the dust ash batching bin 102.

[0054] In some optional embodiments, Figure 2 As shown, the sintering dust removal ash processing system 100 also includes:

[0055] N pressure transmitters 208 correspond to the N gas supply pipelines 203 one by one. Each of the N pressure transmitters 208 is disposed on a corresponding gas supply pipeline 203 to detect an actual pressure value of the gas passing through the corresponding gas supply pipeline 203.

[0056] The control mechanism 205 is electrically connected to the pressure transmitter 208, and is used to determine the number of air supply pipes 203 that need to be connected based on the material level information of the dust ash batching bin 102, the material level information of the ash bin 1013 and the preset standard material level information; receive the actual pressure value sent by the pressure transmitter 208, and determine the number of air supply pipes 203 that are actually connected based on the actual pressure value and the pressure value of the air source 202, and determine the target number of controlling the air pump 204 to be turned on or off based on the difference between the number of air supply pipes 203 that need to be turned on and the number of air supply pipes 203 that are actually turned on, and control the air pump 204 to be turned on or off based on the target number; wherein the target number of controlling the air pump 204 to be turned on or off includes a first target number of controlling the air pump 204 corresponding to the connected air supply pipes 203 to be turned off, or a second target number of controlling the air pump 204 corresponding to the disconnected air supply pipes 203 to be turned on.

[0057] When the number of air supply pipes 203 that need to be connected is less than the actual number that is connected, the first target number is the actual number connected minus the number that needs to be connected, and the air pumps 204 corresponding to the air supply pipes 203 that have been connected can be closed according to the first target number.

[0058] Similarly, when the number of air supply pipes 203 that need to be connected is greater than the number that are actually connected, the second target number is the number that needs to be connected minus the number that are actually connected, and the air pumps 204 corresponding to the air supply pipes 203 that have been connected can be turned on according to the second target number.

[0059] It is understandable that when multiple air supply pipes 203 share one gas source 202, the more air supply pipes 203 are connected, the lower the gas pressure is, and the smaller the power for transporting sintering dust is. Therefore, the number of air supply pipes 203 that are connected must be controlled within an appropriate range.

[0060] It is understandable that the control mechanism controls the air delivery pipeline 203 to be connected by controlling the opening of the corresponding air pump 204 , or controls the air delivery pipeline 203 to be disconnected by controlling the closing of the corresponding air pump 204 .

[0061] In some optional embodiments, the sintering dust removal ash processing system 100 further includes:

[0062] The main pipe valve 209 is arranged on the main pipe.

[0063] The feed pipe valve 210 is disposed on the feed pipe 1012 .

[0064] The control mechanism 205 is electrically connected to the main valve 209 and the feed pipe valve 210 , and is used to control the on and off of the main valve 209 and the feed pipe valve 210 .

[0065] If the main pipe valve 209 and the feed pipe valve 210 are valves with adjustable opening, illustratively, the first controller 2051 is electrically connected to the main pipe valve 209, and the second controller 2052 is electrically connected to the feed pipe valve 210. When the dust ash material level in the dust ash batching bin 102 is too low, the first controller 2051 can also directly control the main pipe valve 209 to increase the opening to increase the conveying amount of dust ash in the main pipe 201. The second controller 2052 can also control the feed pipe valve 210 on the already connected feed pipe 1012 to increase the opening to increase the conveying amount of dust ash in the feed pipe 1012. The second controller 2052 can also control the air pump 204 and the feed pipe valve 210 corresponding to the feed pipe 1012 in the non-conducting state to open simultaneously when receiving the signal sent by the first controller 2051, so as to increase the conveying amount of dust ash.

[0066] Similarly, when the dust ash material level in the dust ash batching bin 102 is too low, the first controller 2051 can also directly control the main pipe valve 209 to reduce the opening, so as to reduce the conveying amount of dust ash in the main pipe 201. The second controller 2052 can also control the opening of the feed pipe valve 210 on the already connected feed pipe 1012 to reduce the conveying amount of dust ash in the feed pipe 1012. The second controller 2052 can also control the air pump 204 and the feed pipe valve 210 corresponding to the feed pipe 1012 in the conductive state to be closed at the same time when receiving the signal sent by the first controller 2051, so as to reduce the conveying amount of dust ash.

[0067] In some optional embodiments, the distance between two adjacent dust collectors 1011 is less than or equal to 30 meters.

[0068] Each conveying assembly 101 includes a plurality of dust collectors 1011 and a feed pipe 1012. The feed pipe 1012 is used to converge the plurality of dust collectors 1011 into a main pipe 201. When the distance between two adjacent dust collectors 1011 is greater than 30 meters, the excessively long distance is not conducive to converging into the same main pipe 201. Therefore, limiting the distance between the dust collectors 1011 is beneficial to saving manufacturing costs.

[0069] In some optional embodiments, the inlet of each of the M dust collectors 1011 is connected to a source of exhaust gas containing smoke, and the sintering dust collected in the ash bin 1013 of each of the M dust collectors 1011 is smoke. The source of exhaust gas containing smoke is usually the head of the sintering machine, and the dust collector 1011 is connected to the head of the sintering machine to remove the smoke from the exhaust gas output by the head of the sintering machine. Exemplarily, the dust collector 1011 connected to the head of the sintering machine can be an electrostatic precipitator.

[0070] In some optional embodiments, the inlet of each of the M dust collectors 1011 is connected to a dust-containing waste gas source, and the sintering dust collected in the ash bin 1013 of each of the M dust collectors 1011 is dust. The dust-containing waste gas source is usually the sintering area, tail of the sintering machine, etc. The dust collector 1011 is connected to the sintering area or tail of the sintering machine to remove the smoke and dust in the waste gas output from the sintering area or tail of the sintering machine. Exemplarily, the dust collector 1011 connected to the tail of the sintering machine can be an electrostatic precipitator or a bag dust collector.

[0071] The characteristics of smoke and dust are different, and the corresponding recycling process parameters are different. Classified collection is conducive to the use of unified parameters for recycling and facilitates unified management.

[0072] In some optional embodiments, a window is provided on the top of the dust ash batching bin 102, and the window is used to release the gas in the dust ash batching bin 102; the window is provided with a dust filtering mechanism 211, which is used to filter the sintering dust ash in the gas released from the window; a fan 212 is provided on the side of the dust filtering mechanism 211 away from the dust ash batching bin 102, which is used to blow the sintering dust ash adsorbed on the dust filtering mechanism 211 back to the dust ash batching bin 102.

[0073] The sintering dust ash in the ash bin 1013 is transported to the dust ash batching bin 102 by gas. The gas is filled into the dust ash batching bin 102, which increases the pressure of the dust ash batching bin 102 and hinders the subsequent feeding. The gas in the batching is released through the window to reduce the pressure of the dust ash batching bin 102, which is convenient for feeding. The dust filtering mechanism 211 blocks the sintering dust ash carried by the gas to prevent the sintering dust ash from being discharged from the dust ash batching bin 102 with the gas and polluting the environment. The fan 212 blows the sintering dust ash adsorbed on the dust filtering mechanism 211 back to the dust ash batching bin 102 to prevent the sintering dust ash adsorbed on the dust filtering mechanism 211 from blocking the gas release channel.

[0074] The combination of the dust filtering mechanism 211 and the fan 212 can be understood as constituting a dust collector. The gas released from the window set at the top of the dust ash batching bin 102 passes through the dust collector, filters the sintered dust ash and retains it in the dust ash batching bin 102, and the dust-collected gas can be directly discharged.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.

[0076] In the description provided herein, a large number of specific details are described.

In some instances, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this description.
