[0024] Clearly, the described embodiments are only a 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 of ordinary skill in the art without creative efforts fall within the protection scope of the present application.

[0025] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0026] Referring to Figs. 1 to 4 The present embodiment provides a dynamic self-adjusting sintering flue gas desulfurization device, which comprises a device main body, the device main body comprises an air inlet zone 2, a transition zone 5, a desulfurizer zone 6 and an air outlet zone 7; the air inlet zone 2 is arranged at the bottom of the device main body and communicates with the flue gas to be treated through an air inlet channel 1, the air outlet zone 7 is arranged at the center of the upper region of the air inlet zone 2, and the top of the air outlet zone 7 is communicated with the outside of the device main body through an air outlet channel 9; the desulfurizer zone 6 is arranged around the four sides of the air outlet zone 7, the transition zone 5 is arranged around the four sides of the desulfurizer zone 6, and the bottom of the transition zone 5 is communicated with the air inlet zone 2; the flue gas passes through the transition zone 5 and then passes through the desulfurizer zone 6 radially to enter the air outlet zone 7; the top of the desulfurizer zone 6 is provided with a charging hole 10, and the bottom is provided with a discharging channel 3 which passes through the device main body and is provided with a rotary discharger 11.

[0027] The above design can make the flue gas pass through the transition zone 5 and then pass through the desulfurizer zone 6 radially, greatly increase the contact area of the flue gas and the desulfurizer and make the contact more uniform, effectively avoid the problem of insufficient desulfurization caused by the dead angle of airflow in the traditional layout, and improve the desulfurization efficiency; on the other hand, the flow field design of bottom air inlet and center air outlet cooperates with the buffering and shunting effect of the transition zone 5, reduces the turbulent flow of the flue gas, significantly reduces the system pressure loss, and reduces the operation energy consumption; the top charging hole 10 and the bottom discharging channel 3 with the rotary discharger 11 form a complete material circulation structure of "charging-reaction-discharging", which provides support for the real-time update of the desulfurizer from top to bottom, can timely supplement fresh desulfurizer and discharge saturated desulfurizer, guarantees the continuous activity of the desulfurizer, avoids the decrease of the desulfurization efficiency, the overall structure is compact and the functions are smoothly connected, which lays a foundation for the dynamic self-adjusting desulfurization of the device, and the function of each region is clear and the connection is smooth, the overall structure is compact, the space utilization rate of the device is optimized, and the working condition demand of the sintering flue gas treatment in the industrial scene is adapted.

[0028] In some optional embodiments, bulk desulfurizer is filled in the desulfurizer zone 6, and the bulk desulfurizer flows in the desulfurizer zone 6 from top to bottom in real time under the adjustment of the rotary discharger 11.

[0029] Further, the detection mechanism is arranged at the outer end of the gas outlet area 7, and is used for monitoring the concentration of sulfur dioxide in the exhaust flue gas. The rotary discharger 11 adjusts the discharging speed in real time according to the data detected by the detection mechanism.

[0030] Further, the bulk desulfurizer can be in the shape of a sphere, a cylinder or the like, and preferably is an activated carbon adsorption desulfurizer.

[0031] By loading the bulk desulfurizer in the shape of a sphere, a cylinder or the like in the desulfurizer area 6, and by adjusting the rotary discharger 11 to realize the real-time flow of the desulfurizer from top to bottom, and by combining the monitoring data of the detection mechanism outside the gas outlet area 7 on the concentration of sulfur dioxide in the exhaust flue gas to dynamically adjust the discharging speed of the rotary discharger 11, the design of the shape of the bulk desulfurizer can increase the contact area with the flue gas, and the selection of the activated carbon can further strengthen the adsorption effect of sulfur dioxide, thereby laying a foundation for efficient desulfurization. The adjustment of the discharging speed based on the real-time concentration of sulfur dioxide can accurately match the update rhythm of the desulfurizer with the content of flue gas pollutants. When the concentration of sulfur dioxide increases, the discharging is accelerated to supplement fresh desulfurizer, thereby avoiding the decrease of the desulfurization efficiency caused by the saturation of the desulfurizer. When the concentration of sulfur dioxide decreases, the discharging is slowed down to reduce the waste of materials, thereby ensuring the stability of the desulfurization effect under different working conditions, significantly improving the utilization rate of the desulfurizer and reducing the operation cost. In addition, the real-time flow of the desulfurizer can also avoid the adsorption failure caused by the long-term residence of the local desulfurizer, thereby further optimizing the overall desulfurization performance of the device.

[0032] In some optional embodiments, the baffle 4 is fixed in the inlet area 2, and is used for making the flue gas in the inlet area 2 flow to the transition area 5 after being divided.

[0033] The structure of the baffle 4 fixed in the inlet area 2 can orderly divide and guide the flue gas entering the inlet area 2, thereby avoiding the local airflow disturbance caused by the direct impact of the flue gas on the internal structure of the device, and reducing the system pressure loss caused by the airflow turbulence. In addition, the flue gas divided by the baffle 4 can uniformly flow to the transition area 5, thereby providing a stable and uniform airflow basis for the subsequent radial flow of the flue gas through the desulfurizer area 6, effectively avoiding the formation of a desulfurization dead angle caused by the local airflow concentration or uneven distribution, ensuring the sufficiency of the contact between the flue gas and the desulfurizer, further improving the desulfurization efficiency in cooperation with the overall partition layout of the device, and meeting the design goal of low resistance and efficient treatment of the sintering flue gas.

[0034] In some optional embodiments, the baffle cone 8 is fixed in the gas outlet area 7, and is used for guiding the flue gas in the gas outlet area 7 to converge and be discharged from the gas outlet of the gas outlet area 7.

[0035] The structure of the draft cone 8 fixed in the gas outlet area 7 can effectively guide the flue gas in the gas outlet area 7 to converge towards the gas outlet of the gas outlet area 7, avoiding the formation of vortex or stagnant dead angle of the flue gas inside the gas outlet area 7, which not only reduces the additional system pressure loss caused by turbulent flow, but also ensures that the flue gas after desulfurization flows smoothly and efficiently through the gas outlet 9. The diversion effect of the baffle plate 4 in the gas inlet area 2 forms a complete and smooth flow field of "ordered diversion of gas inlet - radial penetration of desulfurizing agent - directional convergence of gas outlet", which further optimizes the overall gas flow organization of the device, adapts to the working condition characteristics of large sintering flue gas volume, and ensures that the device maintains stable exhaust efficiency while efficiently desulfurizing, meeting the design requirements of low resistance and efficient treatment of sintering flue gas.

[0036] In some optional embodiments, the transition area 5 and the desulfurizing agent area 6 are separated by an outer basket, and the gas outlet area 7 and the desulfurizing agent area 6 are separated by a central tube; the outer basket and the central tube are both composed of V-shaped grids, the V-shaped grids are composed of several triangular prisms surrounded by arc-shaped mesh, and the spacing of each triangular prism is less than the outer diameter of the bulk desulfurizing agent, and the height of the triangular prism is consistent with the height of the outer basket or the central tube.

[0037] The transition area 5 and the desulfurizing agent area 6 are separated by the outer basket, and the gas outlet area 7 and the desulfurizing agent area 6 are separated by the central tube, both of which are V-shaped grids composed of triangular prisms fixed on the arc-shaped mesh by resistance contact welding, and the spacing of the triangular prisms is less than the outer diameter of the bulk desulfurizing agent. This has many technical advantages: on the one hand, the clear zoning structure can force the flue gas to penetrate the desulfurizing agent area 6 radially after passing through the transition area 5, avoiding direct short-circuiting of the flue gas and ensuring sufficient contact between the flue gas and the desulfurizing agent; on the other hand, the spacing of the triangular prisms being less than the outer diameter of the desulfurizing agent can effectively prevent the loss of desulfurizing agent, and in combination with the structural characteristics of the V-shaped grid, it can avoid the problem of easy clogging of traditional wire mesh or perforated plate, reduce the increase in system pressure drop caused by clogging, and ensure smooth airflow, further realizing low resistance and efficient sintering flue gas desulfurization effect in cooperation with the overall design of the device.

[0038] Further, the triangular prisms are made of corrosion-resistant smooth metal material and are welded on the arc-shaped mesh by resistance contact welding.

[0039] The triangular prisms made of corrosion-resistant smooth metal material can adapt to the working conditions of complex sintering flue gas composition containing corrosive substances, prolonging the service life of the device, and the resistance contact welding connection method ensures the overall strength of the V-shaped grid, meeting the long-term industrial operation requirements.

[0040] In some optional embodiments, the cross section of the triangular prism is an isosceles triangle, several triangular prisms are arranged in a linear array, the isosceles triangle tip of the cross section of the triangular prism is arranged towards the gas outlet area 7 or the transition area 5, and the isosceles triangle base of the cross section of the triangular prism is arranged towards the desulfurizing agent area 6.

[0041] The tip of the isosceles triangular section is directed towards the transition zone 5 or the gas outlet zone 7 on the side of the gas flow, which can greatly reduce the impact resistance when the flue gas flows, adapt to the working condition of large sintering flue gas flow, further reduce the system pressure loss, and match the low resistance design target of the device; and the bottom surface is directed towards the desulfurizing agent zone 6, which can stably support the bulk desulfurizing agent through a larger support surface to avoid local accumulation and displacement of the desulfurizing agent due to gas flow impact or self-flowing, ensure the uniformity of the desulfurizing agent layer, and provide stable conditions for the flue gas to pass through the desulfurizing agent radially; at the same time, the regular layout along the linear array can ensure the uniformity of the overall structure of the V-shaped grid, so that the gas flow is more evenly distributed when passing through the grid, reduces local gas flow turbulence or dead angles, and improves the desulfurization efficiency.

[0042] In the embodiment, the outer basket has a diameter of 1-9.6 m and a height of 2-18.5 m; the center tube has a diameter of 1-2.5 m and a height of 3-18.5 m; the triangular prism has a bottom side length of 5-20 mm and a waist length of 8-30 mm; and the triangular prism has a wedge-shaped gap width of 4-10 mm.

[0043] In some optional embodiments, a blind plate is arranged at the top end of the outer basket and the center tube, and the height of the blind plate is 5-15% of the overall height of the outer basket or the center tube.

[0044] The blind plate can block the flue gas from bypassing the desulfurizing agent zone 6 and directly forming a "short circuit" path between the transition zone 5 and the gas outlet zone 7 from the top, forcing all sintering flue gas entering the device to pass through the transition zone 5 and then pass through the desulfurizing agent zone 6 radially before entering the gas outlet zone 7, completely avoiding the problem of untreated flue gas being directly discharged due to "short circuit" of the flue gas, ensuring sufficient contact between the flue gas and the desulfurizing agent, and further improving the desulfurization efficiency; at the same time, the height of the blind plate is controlled within a reasonable range of 5-15%, which can effectively realize the "anti-short circuit" function, and will not increase the flow resistance of the flue gas due to the excessive height of the blind plate, which is consistent with the overall design target of "low resistance and high efficiency" of the device, and can ensure that the device still maintains good desulfurization effect under the premise of maintaining low pressure loss of the system, which is suitable for the industrial scene requirement of sintering flue gas composition and flow fluctuation.

[0045] In some optional embodiments, multiple groups of the gas inlet channel 1 are symmetrically arranged at the bottom of the device body.

[0046] In combination with the core working condition characteristics of large sintering flue gas volume, the multiple groups of symmetric gas inlet channels 1 can make the flue gas to be treated enter the gas inlet zone 2 from multiple symmetric positions at the bottom of the device simultaneously, avoiding the problem of local concentration of flue gas and airflow deflection caused by a single group of gas inlet channels 1.

[0047] In some optional embodiments, multiple groups of the charging holes 10 are symmetrically arranged at the top of the desulfurizing agent zone 6, and the discharging channels 3 are arranged corresponding to the charging holes 10.

[0048] The multiple sets of symmetrical charging holes 10 can enable fresh bulk desulfurizer to be filled synchronously from multiple symmetrical positions at the top of the desulfurizer area 6, avoiding the problems of local accumulation and uneven filling of desulfurizer caused by single set or asymmetric charging, and ensuring the formation of a uniform and stable desulfurizer layer in the desulfurizer area 6, providing a material basis for the full contact of flue gas with desulfurizer when the flue gas passes through radially; and the design of the discharge channel 3 corresponding to the charging hole 10 can enable the desulfurizer to flow from top to bottom under the action of gravity, forming a stable material circulation path of "top symmetrical charging - middle uniform reaction - bottom corresponding discharge", effectively avoiding the situation of stagnant dead angle or poor flow of desulfurizer in the desulfurizer area 6, ensuring the uniformity of real-time updating of desulfurizer, and preventing the local desulfurizer from reducing the desulfurization efficiency due to long-term stagnation and adsorption saturation.

[0049] In some optional embodiments, sealing valves are arranged in the gas inlet channel 1 and the gas outlet channel 9.

[0050] From the aspects of operation flexibility and maintenance convenience, when the device needs to be shut down for maintenance, replacement of desulfurizer or adjustment of working conditions, the sealing valves can realize the rapid cutting and isolation of the gas channel without the need to shut down the entire flue gas conveying system, improving the operation rate of the device, and preventing the overflow of internal residual harmful flue gas during the maintenance process, ensuring the safety of operation; in addition, in cooperation with the structure of multiple sets of symmetrical arrangement of the gas inlet channel 1, the sealing valves of each gas inlet channel 1 can be individually controlled in terms of opening and closing state and opening degree, assisting in realizing the fine adjustment of the gas inlet amount, further optimizing the initial distribution of flue gas in the gas inlet area 2, and synergistically improving the uniformity of airflow with the shunt effect of the baffle plate 4, providing support for subsequent efficient desulfurization, and meeting the design goal of the device of "high efficiency, stability and adaptation to industrial working conditions".

[0051] The details of the present application are well known to those skilled in the art.
