[0002] In the modern steelmaking process field, especially in the operation process of main steel smelting equipment such as electric furnace and converter, a large amount of flue gas will be produced. These flue gas components are complex, with the increasingly strict environmental protection requirements and the continuous pursuit of energy efficient utilization, flue gas treatment has become a crucial key link, which has the far-reaching significance that can not be ignored for the sustainable development of the whole steel industry.

[0003] These flue gas not only contains a large amount of harmful gas and particulate matter, but also usually has the problem of temperature fluctuation. The temperature difference of flue gas produced in different production processes is large, which brings not small challenge to the subsequent flue gas treatment and heat recovery. If the high temperature component in the flue gas is not effectively controlled, it may affect the normal operation of the subsequent flue gas treatment equipment, and also reduce the efficiency of the heat recovery system.

[0004] At present, in order to deal with the dust and temperature fluctuation in the flue gas, the traditional dust removal equipment mainly uses wet dust removal, bag dust removal, electrostatic dust removal and other ways for treatment.

Specific implementation

[0037] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0038] The embodiments of the present application will be described below in combination with Figures 1 to 8 .

[0039] As shown in Figure 1 , it is a specific implementation of the smoke temperature stabilizing settling chamber provided in the embodiments, which comprises a shell 1, a dust removal module 2 and a temperature stabilizing module 3.

[0040] Specifically, the shell 1 has a smoke inlet 4 and a smoke outlet 5; the dust removal module 2 is arranged inside the shell 1; the temperature stabilizing module 3 is arranged between the outlet of the dust removal module 2 and the smoke outlet 5, the part of the temperature stabilizing module 3 close to the dust removal module 2 adopts a first heat conduction group 6, the part of the temperature stabilizing module 3 close to the smoke outlet 5 adopts a second heat conduction group 7, and the heat conduction coefficient of the first heat conduction group 6 is greater than that of the second heat conduction group 7.

[0041] In this embodiment, the flue gas temperature stabilization settling chamber forms a high-efficiency flue gas treatment system through the organic combination of the shell 1, the dust removal module 2 and the temperature stabilization module 3. The temperature stabilization module 3 is arranged between the outlet of the dust removal module 2 and the flue gas outlet 5 and adjusts the temperature through two groups of heat conduction groups with different thermal conductivities. The part of the temperature stabilization module 3 close to the dust removal module 2 adopts the first heat conduction group 6 with a higher thermal conductivity, which helps to absorb the excess heat in the flue gas; and the part close to the flue gas outlet 5 adopts the second heat conduction group 7 with a lower thermal conductivity, which plays a heat preservation role to keep the temperature of the flue gas stable. Through this design, the temperature of the flue gas can be quickly and uniformly adjusted after the flue gas enters the temperature stabilization module 3, avoiding the influence of temperature fluctuation on the subsequent equipment.

[0042] It should be noted that the specific positions of the flue gas inlet 4 and the flue gas outlet 5 are not limited in this embodiment. The flue gas inlet 4 and the flue gas outlet 5 can be arranged on the upper surface of the shell 1 or on the side surface of the shell 1. According to the actual installation requirements and process requirements, the positions of the flue gas inlet 4 and the flue gas outlet 5 can be flexibly adjusted to achieve the best flue gas flow and treatment effect. If the flue gas inlet 4 and the flue gas outlet 5 are arranged on the upper surface of the shell 1, the gravity can be better utilized to promote the flow of the flue gas, and the connection with the steelmaking equipment is facilitated. If they are arranged on the side surface of the shell 1, the pipeline layout can be adjusted according to the space layout requirements, saving space and optimizing the overall design of the system.

[0043] As shown in Figure 2 , a specific embodiment of the flue gas temperature stabilization settling chamber provided in this embodiment, the temperature stabilization module 3 includes a plurality of cylindrical heat conduction pieces 8 arranged in parallel and at intervals.

[0044] Specifically, the temperature stabilization module 3 includes a plurality of cylindrical heat conduction pieces 8 arranged in parallel and at intervals. These cylindrical heat conduction pieces 8 are arranged at a certain interval to ensure that the flue gas can fully contact the heat conduction pieces when flowing through the temperature stabilization module 3, thereby achieving effective temperature adjustment. The structural design of the cylindrical heat conduction piece 8 enables it to absorb or release heat to the maximum extent during the flow of the flue gas, improving the heat exchange efficiency of the temperature stabilization module 3.

[0045] As shown in Figure 3 , a specific embodiment of the flue gas temperature stabilization settling chamber provided in this embodiment, the cylindrical heat conduction pieces 8 in the first heat conduction group 6 are made of cast iron, steel or silicon carbide material.

[0046] Specifically, the gray-filled circular cross-section is the first heat conduction group 6, and the cylindrical heat conduction member 8 in the first heat conduction group 6 adopts cast iron, steel or silicon carbide material. The selection of these materials takes into account their superior heat conduction performance and high temperature resistance characteristics, which can maintain stable heat conduction efficiency in high temperature environment. Cast iron, steel and silicon carbide materials all have high thermal conductivity, which helps the temperature stabilizing module 3 to quickly absorb and conduct heat when the flue gas flows through, thereby achieving rapid temperature regulation.

[0047] In addition, in other embodiments, the first heat conduction group 6 can also select materials with large heat conduction coefficients such as copper, aluminum and silicon nitride, which can effectively improve the heat exchange efficiency and ensure the long-term stable operation of the equipment in high temperature environment.

[0048] As shown in Figure 1 , a specific implementation of the flue gas temperature stabilizing settling chamber provided in the present embodiment, the cylindrical heat conduction member 8 in the second heat conduction group 7 adopts refractory material.

[0049] Specifically, the white-filled circular cross-section is the second heat conduction group 7, and the cylindrical heat conduction member 8 in the second heat conduction group 7 can adopt refractory materials such as refractory bricks, zirconia corundum and aluminum silicate fibers. The thermal conductivity of refractory materials is relatively low, which can effectively slow down the transfer of heat and ensure that the design of the temperature stabilizing module 3 can remain stable in the case of large changes in flue gas temperature, preventing excessive temperature from affecting the subsequent processing process. At the same time, the high temperature resistance of refractory materials can ensure that they are not damaged in high temperature flue gas environment, thereby improving the durability and service life of the equipment. This configuration helps to extend the operating cycle of the equipment and improve energy utilization efficiency while ensuring temperature stability.

[0050] As shown in Figure 4 , a specific implementation of the flue gas temperature stabilizing settling chamber provided in the present embodiment, the cylindrical heat conduction member 8 in the first heat conduction group 6 adopts a solid structure.

[0051] Specifically, the solid-filled circular cross-section is the first heat conduction group 6, and the cylindrical heat conduction member 8 in the first heat conduction group 6 adopts a solid structure, which helps to enhance the heat conduction efficiency. The solid structure of the cylindrical heat conduction member 8 can maximize the speed of heat transfer, thereby more effectively regulating the temperature of the flue gas and ensuring that the flue gas can quickly distribute heat uniformly when passing through the temperature stabilizing module 3. In addition, the heat conduction member with solid structure generally has higher heat quality than the heat conduction member with hollow structure, which can better store and conduct heat, which helps to maintain stable temperature control in the case of large fluctuations in flue gas temperature.

[0052] As shown in Figure 4As shown, this is a specific implementation of the flue gas temperature stabilization settling chamber provided in this embodiment. The cylindrical heat-conducting element 8 in the second thermal conductivity group 7 adopts a hollow structure.

[0053] Specifically, the hollow-filled circular cross-section is the second thermal conductivity group 7. The cylindrical heat-conducting element 8 in the second thermal conductivity group 7 adopts a hollow structure, which can effectively reduce the overall weight of the temperature stabilization module 3 and improve the slow heat transfer characteristics. The hollow cylindrical heat-conducting element 8 can form a certain air gap inside it. This air layer has low thermal conductivity, thereby reducing the rapid conduction of heat and helping to play a better temperature buffering role when flue gas flows through it, thus achieving more stable temperature control.

[0054] like Figure 3 As shown, this is a specific implementation of the flue gas temperature stabilization settling chamber provided in this embodiment. The temperature stabilization module 3 is a rectangular structure arranged horizontally, and the length direction of the temperature stabilization module 3 is parallel to the length direction of the shell 1.

[0055] Specifically, by arranging the temperature stabilizing module 3 parallel to the length of the housing 1, the flue gas can flow evenly through the temperature stabilizing module 3 and fully contact the cylindrical heat-conducting element 8, thereby achieving effective temperature regulation and stabilization. Simultaneously, this structural layout reduces resistance in fluid dynamics, ensuring smooth flue gas flow and efficient heat exchange. The transversely rectangular structure of the temperature stabilizing module 3 provides a large heat exchange area within a limited space, improving heat recovery efficiency. Furthermore, this arrangement facilitates modular design, making the installation, maintenance, and replacement of the temperature stabilizing module 3 more convenient, enhancing the system's flexibility and scalability.

[0056] It should be noted that the temperature stabilization effect is as follows: Figure 6 , Figure 7 As shown, the temperature at the four flue gas inlet points fluctuates between 250℃ and 900℃. After passing through the horizontally arranged temperature stabilization module 3, the flue gas temperature stabilizes between 390℃ and 510℃, fully utilizing the temperature regulation effect of the module. This ensures good temperature control of the flue gas within different temperature ranges, unaffected by temperature difference variations. This provides a more stable temperature environment for subsequent flue gas treatment and heat recovery, ensuring efficient system operation and reducing energy waste and equipment wear caused by temperature fluctuations.

[0057] like Figure 5 As shown, this is a specific implementation of the flue gas temperature stabilization settling chamber provided in this embodiment. The two ends of the cylindrical heat-conducting component 8 are fixedly installed by the support structure 9, and the cross section of the support structure 9 is a regular hexagon.

[0058] Specifically, the regular hexagonal cross-sectional shape can effectively distribute and withstand thermal stress from the heat-conducting member, ensuring that it does not deform or break down in a high-temperature environment. In addition, the hexagonal geometry can also optimize space utilization and improve the overall heat exchange efficiency of the temperature stabilization module 3. Through this structural design, the support structure 9 can evenly distribute the heat transfer between the cylindrical heat-conducting members 8, while enhancing the stability and durability of the system, further improving the working performance of the flue gas temperature stabilization settling chamber.

[0059] As shown in Figure 8 , a specific embodiment of the flue gas temperature stabilization settling chamber provided by the present embodiment, the dust removal module 2 includes a plurality of vertically spaced dust removal plate groups 10, the dust removal plate group 10 has a plurality of dust removal plates connected in sequence, and the adjacent two dust removal plates in the dust removal plate group 10 are connected at an angle.

[0060] Specifically, the plurality of dust removal plates in the dust removal plate group 10 form a group of overall structures by being connected in sequence, and the adjacent two dust removal plates are connected at an angle. Through this arrangement, the angular connection of the dust removal plates can effectively increase the resistance of the flue gas flow, prompting the particulate matter in the flue gas to be more fully collided and settled when passing through the dust removal plate group 10, thereby improving the dust removal efficiency.

[0061] As shown in Figure 1 , a specific embodiment of the flue gas temperature stabilization settling chamber provided by the present embodiment, the flue gas inlet 4 and the flue gas outlet 5 are arranged on the upper surface of the shell 1; the bottom of the shell 1 is provided with a plurality of uniformly distributed ash hoppers 11.

[0062] Specifically, the flue gas inlet 4 and the flue gas outlet 5 are arranged on the upper surface of the shell 1, ensuring the smoothness of the flue gas flow and facilitating the installation and maintenance of the equipment. The design of the upper surface helps to avoid the blockage or backflow phenomenon that may occur during the flue gas treatment process. At the same time, the plurality of uniformly distributed ash hoppers 11 arranged at the bottom of the shell 1 can effectively collect the settled dust and particulate matter, and prevent the dust from accumulating inside the equipment, thereby ensuring the long-term stable operation of the equipment. Through this design, the dust removal effect can be improved, and the later cleaning and maintenance can be facilitated.

[0063] In addition, in other embodiments, the flue gas inlet 4 and the flue gas outlet 5 are arranged on the side surface of the shell 1, which can provide more flexibility according to the actual installation space and process requirements. If the flue gas inlet is arranged on the left side, the high-efficiency separation blade can be directly arranged at the inlet, so that the flue gas can be subjected to intensive dust removal when entering the settling chamber. This arrangement design can significantly improve the dust removal effect, reduce the load of the heat storage module, and prolong the service life of the equipment.

[0064] Working principle:

[0065] The flue gas first enters the shell 1 through the flue gas inlet 4 and passes through the dust removal module 2 arranged inside the shell 1. The dust removal module 2 is composed of a plurality of vertically spaced dust removal plate groups 10, and the particulate matter is effectively removed when the flue gas passes through these dust removal plates. After dust removal, the flue gas temperature is relatively high and fluctuates to some extent, so the flue gas continues to flow through the temperature stabilizing module 3. The temperature stabilizing module 3 is composed of a cylindrical heat conducting part 8, and the material and structural design of the heat conducting part make the temperature fluctuation be adjusted. Specifically, the part of the temperature stabilizing module 3 close to the dust removal module 2 adopts a material with a higher thermal conductivity to quickly take away excess heat, and the part close to the flue gas outlet 5 adopts a material with a lower thermal conductivity to slow down heat loss, thereby maintaining the stability of the flue gas temperature. Through this design, the flue gas temperature can be stabilized within a certain range, ensuring the effect of subsequent heat recovery and flue gas emission. Finally, the stabilized flue gas is discharged through the flue gas outlet 5, and the whole process effectively realizes the purification and temperature control of the flue gas.

[0066] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes are also within the scope of the present application.
