Description

Technical Field

[0001] This application belongs to the technical field of lime kiln components, and more specifically, relates to an air intake beam for reducing overall energy consumption. Background Technology

[0002] The suction beam is a special pipe structure installed at the top of the cooling zone of a lime kiln. It is buried in the stone inside the kiln and connected to an external induced draft fan to extract the waste gas from the kiln.

[0003] The existing air intake beam includes an air intake pipe with air intake ports located on both sides of its bottom. The air intake pipe is embedded in the stone, and the stone naturally forms a V-shaped air duct at the bottom of the air intake pipe.

[0004] The air inlets on both sides of the suction pipe are close to the stone, which increases the local resistance of the air inlets. At the same time, the airflow from both sides collides in the pipe after being drawn in, generating eddies and turbulence losses, which leads to an increase in the load on the induced draft fan and an increase in energy consumption. Furthermore, the airflow at the air inlet can only be drawn in from the limited area of ​​the gaps between the stones, which increases the wind speed and wind pressure, making it very easy for the stones to be drawn into the pipe or block the air inlet. Utility Model Content

[0005] The purpose of this application is to provide an air intake beam that reduces overall energy consumption, in order to solve the technical problems in the prior art, such as large local resistance at the air intake, increased load on the induced draft fan, and increased energy consumption; and that the airflow at the air intake can only be drawn in from the limited area of ​​the stone gaps, which increases wind speed and wind pressure, and makes it easy for the stone to be sucked into the pipe or block the air intake.

[0006] To achieve the above objectives, the technical solution adopted in this application is: to provide an air-absorbing beam that reduces overall energy consumption, including an air-absorbing pipe located inside the stone, wherein the air-absorbing pipe has multiple air-absorbing ports along its own length direction, the air-absorbing ports opening downwards and located at the middle position of the bottom of the air-absorbing pipe.

[0007] In one possible implementation, based on the above technical solutions, the air-suction beam further includes: Two cooling support beams are connected below the air intake pipe and are hollow inside. The two cooling support beams are located on both sides of the air intake. An air intake channel communicating with the air intake is formed between the two cooling support beams.

[0008] In one possible implementation, based on the above technical solutions, the air-suction beam further includes: A short intake tube is provided at the intake port and extends downward into the intake channel.

[0009] In one possible implementation, based on the above technical solutions, the air inhalation tube is cylindrical.

[0010] In one possible implementation, based on the above technical solutions, the outer surface of the cooling support beam that contacts the stone is a vertical plane or an inclined plane that slopes outward from top to bottom.

[0011] In one possible implementation, based on the above technical solutions, the air-suction beam further includes: A cooling sleeve is fitted over the outside of the intake pipe, forming a cooling air duct between the cooling sleeve and the intake pipe, and the short intake pipe extends downward through the cooling sleeve; and Multiple support fins are located within the cooling air duct and connected to the cooling sleeve and the air intake pipe.

[0012] In one possible implementation, based on the above technical solutions, the air-suction beam further includes: Several cooling guard beams are arranged on the outside of the air intake pipe, and the interior of the cooling guard beams has cooling air ducts that directly contact the outer wall of the air intake pipe.

[0013] In one possible implementation, based on the above technical solutions, one end of the cooling guard beam is connected to the cooling support beam.

[0014] In one possible implementation, based on the above technical solutions, the cooling guard beam has three beams, one of which is located at the middle of the top of the air intake pipe, and the other two are symmetrically arranged on both sides of the top of the air intake pipe.

[0015] In one possible implementation, based on the above technical solutions, the bottom of the air intake pipe is provided with multiple support plates, and each support plate is located between two adjacent air intake ports.

[0016] The beneficial effects of the suction beam for reducing overall energy consumption provided in this application are as follows: Compared with the prior art, this application avoids airflow concentration on one side by setting the suction port in the middle of the bottom, allowing airflow to enter the suction pipe more evenly from all directions, thereby improving suction efficiency; and by reasonably setting the position of the suction port, this application increases the distance between it and the stone, effectively reducing local resistance; the reduction of local resistance reduces the resistance that the induced draft fan needs to overcome during operation, thereby reducing the load on the induced draft fan, which directly leads to a decrease in energy consumption, achieving the goal of reducing overall energy consumption; due to the increased distance between the suction port and the stone, the airflow at the suction port is no longer limited to being drawn in from the limited area of ​​the stone gaps, and the wind speed and wind pressure are relatively stable, reducing the possibility of stone being sucked into the pipe or blocking the air vent.

[0025] In the description of this application, "multiple" means two or more, and "several" means one or more, unless otherwise expressly and specifically defined.

[0026] The present application will now describe an air-absorbing beam that reduces overall energy consumption.

[0027] like Figure 1 As shown, one embodiment of this application provides an air-absorbing beam for reducing overall energy consumption, including an air-absorbing pipe 1 located inside the stone. The bottom of the air-absorbing pipe 1 is provided with a plurality of air-absorbing ports 11 spaced apart along its own length direction. The air-absorbing ports 11 open downwards and are located at the middle position of the bottom of the air-absorbing pipe 1.

[0028] This embodiment provides an air intake beam that reduces overall energy consumption. Compared with the prior art, by setting the air intake 11 at the middle of the bottom, the airflow is prevented from concentrating on one side, so that the airflow can enter the air intake pipe 1 more evenly from all directions, thereby improving the air intake efficiency.

[0029] Furthermore, by reasonably setting the position of the air intake 11, this application increases the distance between it and the stone, effectively reducing local resistance. The reduction in local resistance reduces the resistance that the induced draft fan needs to overcome during operation, thereby reducing the load on the induced draft fan. The reduction in the load on the induced draft fan directly leads to a decrease in energy consumption, achieving the goal of reducing overall energy consumption.

[0030] As the distance between the air intake 11 and the stone increases, the airflow at the air intake 11 is no longer limited to being drawn in from the gaps between the stones, and the wind speed and wind pressure are relatively stable, reducing the possibility of the stone being sucked into the pipe or blocking the air intake.

[0031] like Figure 1 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The intake beam also includes two cooling support beams 2, which are connected below the intake pipe 1 and are hollow inside. The two cooling support beams 2 are located on both sides of the intake port 11; an intake channel communicating with the intake port 11 is formed between the two cooling support beams 2.

[0032] For cooling, the cooling support beam 2 is hollow inside, and its outer end can be connected to a blower to bring in outside air. When outside air enters the cooling support beam 2, it can exchange heat with the suction pipe 1, thereby cooling the suction pipe 1. Cooling the suction pipe 1 through the cooling support beam 2 can effectively reduce the temperature of the suction pipe 1 and extend its service life. Furthermore, the gas discharged from the cooling support beam 2 can provide secondary combustion support for the lime kiln.

[0033] The two cooling support beams 2 and the air inlet channel further increase the distance between the air intake 11 and the stone, which helps to reduce local resistance and prevent blockage. At the same time, the cooling support beams 2 can also provide stable support for the air intake pipe 1. Inside the lime kiln, the air intake pipe 1 needs to withstand a certain pressure and weight. The cooling support beams 2 provide additional support for the air intake pipe 1, ensuring its stability and safety in complex working environments.

[0034] like Figure 1 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The air intake beam also includes an air intake short pipe 3, which is located at the air intake port 11 and extends downward into the air intake channel.

[0035] During the inhalation process, the inhalation port 11 is subjected to significant airflow pressure and impact, making it prone to damage or deformation. The inhalation short tube 3 is equivalent to adding a reinforcing structure to the inhalation port 11, improving its strength and stability and reducing the risk of damage.

[0036] When airflow enters the intake pipe 1 from the intake port 11, the intake short pipe 3 guides the airflow in a specific direction and path, preventing turbulence or eddies from forming at the intake port 11. This orderly airflow helps improve intake efficiency, reduce energy loss, and further lower overall energy consumption.

[0037] like Figure 1As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The inhalation tube 1 is cylindrical.

[0038] The cylindrical intake pipe 1 has a relatively regular internal space, and the airflow experiences less resistance when flowing through it. The cylindrical structure allows the airflow to pass through more smoothly, reducing collisions and friction of the airflow inside the pipe, thereby reducing energy loss.

[0039] Furthermore, the cylindrical shape is relatively simple to manufacture, has a lower cost, and is easier to connect and cooperate with other components during installation.

[0040] like Figure 1 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The outer surface of the cooling support beam 2 that contacts the stone is a vertical plane or an inclined plane sloping outward from top to bottom. In this embodiment, it is specifically a vertical plane.

[0041] The outer surface of the cooling support beam 2 that contacts the stone is a vertical plane or an inclined plane that slopes outward from top to bottom, which can provide stable support for the air intake pipe 1 and improve the stone's resistance to pressure.

[0042] Furthermore, the outer surface of the cooling support beam 2 can block and support the stone, thereby increasing the size of the V-shaped air duct below the suction pipe 1 and making it more stable. The increase in the size of the V-shaped air duct provides a wider flow space for the airflow, which helps to reduce airflow resistance and improve suction efficiency.

[0043] like Figure 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The air intake beam also includes a cooling sleeve 4 and multiple support fins 5; the cooling sleeve 4 is sleeved on the outside of the air intake pipe 1, and a cooling air duct is formed between the cooling sleeve 4 and the air intake pipe 1, and the short air intake pipe 3 passes through the cooling sleeve 4 downward; the multiple support fins 5 are located in the cooling air duct and are connected to the cooling sleeve 4 and the air intake pipe 1.

[0044] The outer end of the cooling sleeve 4 can be connected to a blower to bring in outside air. When the outside air enters the cooling duct, it can fully exchange heat with the suction pipe 1, thereby cooling the suction pipe 1. In conjunction with the cooling support beam 2, the cooling sleeve 4 can cool the suction pipe 1 from the outside, forming a comprehensive cooling system that greatly improves the cooling effect on the suction pipe 1. Furthermore, the gas discharged from the cooling sleeve 4 can also provide secondary combustion support for the lime kiln.

[0045] like Figure 3As shown, in some possible embodiments, the intake beam further includes several cooling guard beams 6, which are disposed on the outside of the intake pipe 1, and have cooling air ducts inside the cooling guard beams 6 that directly contact the outer wall of the intake pipe 1.

[0046] To simplify the structure and reduce costs, a cooling beam 6 can be used instead of the cooling sleeve 4 and the support fins 5. The cooling beam 6 is fixed to the intake pipe 1 along its length, which enhances the strength of the intake pipe 1 and achieves a cooling effect. The cooling beam 6 has a cooling air duct inside that directly contacts the outer wall of the intake pipe 1, and its outer end can be connected to a blower to bring in outside air. When outside air enters the cooling air duct, it can exchange heat with the intake pipe 1, thereby cooling the intake pipe 1.

[0047] In addition, to further reduce costs, both ends of the cooling beam 6 can be directly connected to the outside atmosphere. The density and pressure differences formed by the temperature difference between the cooling support beam 2 and the cooling beam 6 cavity allow the air inside the cooling beam 6 to flow naturally.

[0048] Optionally, one end of the cooling guard beam 6 is connected to the cooling support beam 2.

[0049] A single blower can achieve simultaneous gas flow within both the cooling support beam 2 and the cooling guard beam 6, reducing equipment costs and energy consumption. After the gas enters the cooling support beam 2 from the blower, a portion of the gas can enter the cooling guard beam 6 through the connecting port, achieving comprehensive cooling of the intake pipe 1.

[0050] Specifically, the cooling guard beam 6 has three beams, one of which is located at the top center of the intake pipe 1, and the other two are symmetrically arranged on both sides of the top of the intake pipe 1.

[0051] The uniformly distributed design allows the cooling beam 6 to cool the top of the intake pipe 1 evenly, avoiding local overheating; it helps to improve the performance and service life of the intake pipe 1 and reduce thermal stress and deformation caused by uneven temperature.

[0052] In terms of cooling, the cooling guard beam 6 works in conjunction with the cooling support beam 2 below to form a comprehensive cooling system. The cooling support beam 2 cools from below the intake pipe 1, while the cooling guard beam 6 cools from the top of the intake pipe 1. The two work together to more effectively reduce the temperature of the intake pipe 1.

[0053] Optionally, the bottom of the suction pipe 1 is provided with multiple support plates, each support plate being located between two adjacent suction ports 11.

[0054] Each support plate is located between two adjacent air inlets 11, providing additional support for the air inlet tube 1, increasing the support points of the air inlet tube 1, and improving the stability of the air inlet tube 1.
