Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0032] Although the present invention can be readily embodied in various forms, only some specific embodiments are shown in the accompanying drawings and will be described in detail in this specification. It is understood that this specification should be regarded as an exemplary illustration of the principles of the present invention and is not intended to limit the present invention to what is described herein.

[0033] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0034] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various elements of this invention are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, these directional indications also change accordingly.

[0035] Currently, flue gas pollutant removal processes typically use individual units to treat one or more pollutants. Examples include desulfurization in an absorption tower, dust removal in a baghouse dust collector, and denitrification in a denitrification reactor. These flue gas treatment units are connected via ductwork. Elbows and other bends in these ductwork can cause localized losses. Furthermore, numerous ductwork increases system friction loss and leakage, leading to increased system resistance and airflow, and consequently, increased power consumption of the system fans. When treating multiple pollutants, multiple individual units are connected in series via ductwork. However, the large heat dissipation area of ​​the ductwork results in significant heat loss from the flue gas pollutant removal equipment, reducing denitrification efficiency under low-temperature denitrification conditions. Additionally, treating the flue gas with multiple individual units results in a large footprint for the entire flue gas pollutant removal system.

[0036] This utility model provides an integrated flue gas pollutant removal device that can solve some or all of the above-mentioned technical problems.

[0037] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1 This is a schematic diagram of the structure of an integrated flue gas pollutant removal device provided in an embodiment of this utility model. Figure 2 yes Figure 1 The diagram shown is a structural schematic of the integrated flue gas pollutant removal equipment from another perspective. Figure 3 yes Figure 1 The diagram shows the flue gas flow direction of the integrated flue gas pollutant removal equipment. Figure 4 yes Figure 2 The schematic diagram of the flue gas flow direction in the integrated flue gas pollutant removal equipment shown illustrates that... Figure 1 and Figure 2 The diagram shows a portion of the internal structure of the integrated flue gas pollutant removal device from the current perspective, to make the structure of the integrated flue gas pollutant removal device clearer. Figure 3 and Figure 4 The black arrows in the diagram indicate the direction of gas flow. The integrated flue gas pollutant removal equipment may include: an acid gas removal device 11, a multi-pollutant synergistic removal device 12, a dust removal device 13, a denitrification device 14, and a flue gas exhaust device 15.

[0038] The inlet of the acid gas removal device 11 is used to introduce the flue gas to be treated. The flue gas to be treated may include industrial flue gas generated by main units such as boilers, steel sintering pellets, and industrial furnaces. The flue gas to be treated can react with the quicklime in the acid gas removal device 11. Most of the strong acid gases are removed in the acid gas removal device 11. For example, the strong acid gases may include SO3, HCl, HF, etc.

[0039] The inlet of the multi-pollutant synergistic removal device 12 can be connected to the outlet of the acid gas removal device 11; the flue gas after acid gas removal can enter the multi-pollutant synergistic removal device 12, which can remove pollutants such as heavy metals, dioxins and SO2 from the flue gas. For example, heavy metals, dioxins and SO2 can be removed by quicklime and other additives (such as activated carbon) in the multi-pollutant synergistic removal device 12.

[0040] The air inlet of the dust removal device 13 can be connected to the air outlet of the multi-pollutant synergistic removal device 12, allowing the flue gas passing through the multi-pollutant synergistic removal device 12 to enter the dust removal device 13 for dust removal treatment. The dust removal device 13 includes two dust removal components 131, with the multi-pollutant synergistic removal device 12 located between and connected to the two dust removal components 131. The portion of the housing of the multi-pollutant synergistic removal device 12 closest to the dust removal component 131 is reused with the portion of the housing of the two dust removal components 131 closest to the multi-pollutant synergistic removal device 12. That is, a portion of the housing of the multi-pollutant synergistic removal device 12 and a portion of the housing of the two dust removal components 131 can share a side plate. Thus, by integrating the multi-pollutant synergistic removal device 12 and the dust removal device 13 together, the compactness of the integrated flue gas pollutant removal equipment can be improved, and the volume of the integrated flue gas pollutant removal equipment can be reduced. It is understood that the dust removal device 13 may also include three, four, or more dust removal components 131; this embodiment of the invention does not limit this.

[0041] For example, the housing of the multi-pollutant synergistic removal device 12 includes two first side plates 121 and three second side plates 122. The two first side plates 121 can be reused as part of the housing of two dust removal components 131, and the three second side plates 122 are part of the housing used independently by the multi-pollutant synergistic removal device 12. Both sides of the three second side plates 122 are connected to the two dust removal components 131.

[0042] Furthermore, compared to the multi-pollutant synergistic removal device 12 and dust removal device 13 being connected by welding or bolts, this embodiment of the invention connects the multi-pollutant synergistic removal device 12 and dust removal device 13 through a reused partial shell, forming a continuous support structure between the two devices. Bolts reduce weak points in the connection, thereby enhancing the overall deformation resistance of the structure. In addition, it also reduces the amount of material used in the manufacturing process.

[0043] The inlet of the denitrification device 14 is connected to the outlet of the dust removal device 13, and the outlet of the denitrification device 14 is connected to the flue gas exhaust device 15. After dust removal, the flue gas enters the denitrification device 14. The denitrification device 14 may include a catalyst section 141, which contains a catalyst. The denitrification device 14 utilizes the catalyst and NH3 to remove NO... X The process involves reduction to produce nitrogen and water. The purified flue gas is then discharged into the external environment through a flue gas exhaust device 15. For example, the flue gas exhaust device 15 includes an induced draft fan that can be connected to a chimney so that the induced draft fan can guide the purified flue gas to the chimney and then discharge it into the atmosphere.

[0044] In summary, this utility model embodiment provides an integrated flue gas pollutant removal device including an acid gas removal device 11, a multi-pollutant synergistic removal device 12, a dust removal device 13, a denitrification device 14, and a flue gas exhaust device 15. The dust removal device 13 includes two dust removal components 131. The multi-pollutant synergistic removal device 12 is located between and connected to the two dust removal components 131. The portion of the housing of the multi-pollutant synergistic removal device 12 closest to the dust removal components 131 is reused with the portion of the housing of the two dust removal components 131 closest to the multi-pollutant synergistic removal device 12. By integrating the multi-pollutant synergistic removal device 12 and the dust removal device 13 together, the layout compactness of the integrated flue gas pollutant removal device can be improved, and the volume of the integrated flue gas pollutant removal device can be reduced. In this way, the flue gas flow in the integrated flue gas pollutant removal device can be shortened, and the connecting flues used for connecting multiple devices in series can be reduced, thereby reducing the resistance loss, heat loss, and system air leakage of the connecting flues, achieving the effect of saving operating energy consumption and reducing the footprint.

[0045] Please refer to Figure 1 In an optional embodiment, the integrated flue gas pollutant removal device may further include a first flow guiding device 16, which is installed at the air inlet of the acid gas removal device 11. The first flow guiding device 16 may include a multi-stage blade guide to ensure uniform distribution of the airflow entering the acid gas removal device 11.

[0046] In one exemplary embodiment, the following reactions can be performed in the acid gas removal device 11:

[0047] Ca(OH)2+SO3=CaSO4·1 / 2H2O+1 / 2H2O.

[0048] Ca(OH)2 + 2HCl = CaCl2·2H2O.

[0049] Ca(OH)2 + 2HF = CaF2 + 2H2O.

[0050] Please refer to Figure 1In an optional real-time mode, the integrated flue gas pollutant removal equipment further includes a Venturi accelerator 17, located between the acid gas removal device 11 and the multi-pollutant synergistic removal device 12. The inlet of the Venturi accelerator 17 is connected to the outlet of the acid gas removal device 11, and the outlet of the Venturi accelerator 17 is connected to the multi-pollutant synergistic removal device 12. Along the flue gas flow direction, the diameter of the flue gas flow channel in the Venturi accelerator 17 can first decrease and then increase.

[0051] In the multi-pollutant synergistic removal device 12, the flue gas can first flow upward and then downward, allowing for a sufficiently long reaction time. The flue gas is accelerated by the Venturi accelerator 17, which generates intense turbulence, ensuring sufficient contact between the gas and solid within the Venturi accelerator 17 and thus improving reaction efficiency. For example, in the multi-pollutant synergistic removal device 12, heavy metals and dioxins can be synergistically removed through the physical adsorption, chemical transformation, and solid solution action of the desulfurizing agent and adsorbent.

[0052] In one exemplary embodiment, the following reactions can be carried out in the multi-pollutant synergistic removal device 12:

[0053] Ca(OH)2+SO2=CaSO3·1 / 2H2O+1 / 2H2O.

[0054] CaSO3·1 / 2H2O+1 / 2O2=CaSO4·1 / 2H2O.

[0055] Ca(OH)2 + CO2 = CaCO3 + H2O.

[0056] Please refer to Figure 2 In an optional embodiment, the air inlet 13k1 of the dust collector can be located on the side of the air outlet 13k2 of the dust collector closer to the ground. Optionally, the dust collection component 131 of the dust collector 13 includes a dust hopper 1311, filter bags 1312, a tube sheet 1313, and a pulse jet cleaner 1314; the dust hopper 1311 is installed at the lower end of the housing of the dust collection component 131; the filter bags 1312, the tube sheet 1313, and the pulse jet cleaner 1314 are all installed in the housing of the dust collection component 131 and arranged sequentially in a direction away from the dust hopper 1311. The dust hopper 1311 is located at the bottom of the dust collection component 131, which facilitates dust collection and cleaning, making the overall structure more compact.

[0057] The dust removal device 13 is connected to the multi-pollutant synergistic removal device 12 and the denitrification device 14 respectively, using a bottom-inlet and top-outlet airflow method. When the flue gas enters from the bottom of the dust removal device 13, the coarse dust particles in the flue gas naturally settle due to gravity, which can reduce the load on the filter bags 1312 in the dust removal device 13. At the same time, the rising airflow and the falling dust form a counter-movement, which enhances the inertial separation effect and improves the dust removal efficiency.

[0058] Please refer to Figure 1 and Figure 2 In an optional embodiment, the denitrification device 14 can be located between and connected to the two dust removal components 131. The portion of the housing of the denitrification device 14 closest to the dust removal components 131 is reused with the portion of the housing of the two dust removal components 131 closest to the denitrification device 14. That is, a portion of the housing of the denitrification device 14 and a portion of the housing of the two dust removal components 131 can share a side plate. Thus, by integrating the denitrification device 14 and the dust removal device 131 together, the layout compactness of the integrated flue gas pollutant removal equipment can be improved, and the volume of the integrated flue gas pollutant removal equipment can be reduced. The denitrification device 14 can be arranged adjacent to and connected to the multi-pollutant co-removal device 12. That is, the portion of the housing of the multi-pollutant co-removal device 12 closest to the denitrification device 14 can be reused with the portion of the housing of the denitrification device 14 closest to the multi-pollutant co-removal device 12. This further improves the layout compactness of the integrated flue gas pollutant removal equipment.

[0059] In one exemplary embodiment, the following reactions can be carried out in the denitrification device 14:

[0060] 4NH3 + 4NO + O2 = 4N2 + 6H2O.

[0061] 8NH3 + 6NO2 = 7N2 + 12H2O.

[0062] 4NH3 + 2NO2 + O2 = 3N2 + 6H2O.

[0063] In one exemplary embodiment, the denitrification device 14 may also be installed directly above the tube sheet 1313 of the dust removal assembly 131, or above the middle area of ​​the two dust removal assemblies 131.

[0064] In an optional embodiment, the integrated flue gas pollutant removal device may further include a second flow guiding device 18, which is installed at the outlet of the dust removal assembly 131. The second flow guiding device 18 may include multi-layer flow guiding grids and can be used to uniformly distribute the airflow entering the denitrification device 14.

[0065] In one optional embodiment, the integrated flue gas pollutant removal equipment may further include a material circulation channel L1; one end of the material circulation channel L1 is connected to the dust removal device 13, and the other end is connected to the acid gas removal device 11. Optionally, the integrated flue gas pollutant removal equipment may also include an ash discharge channel L2, one end of which is connected to the dust removal device 13, and the other end is connected to the ash silo.

[0066] Dust removal device 13 can collect dust in flue gas. Part of the dust, including unreacted absorbent, is returned to acid gas removal device 11 for reuse through material circulation channel L1. The other part of the dust is discharged through external ash discharge channel L2, on which a silo pump can be installed.

[0067] In one optional embodiment, the integrated flue gas pollutant removal equipment further includes a mounting bracket 19, on which the acid gas removal device 11, the multi-pollutant synergistic removal device 12, the dust removal device 13, the denitrification device 14, and the exhaust device 15 are all mounted. The mounting bracket 19 may be made of steel.

[0068] In one exemplary embodiment, the operation process of the integrated flue gas pollutant removal device in this utility model embodiment may include the following steps:

[0069] (1) The flue gas to be treated enters the inlet of the integrated flue gas pollutant removal equipment and passes through the first guide device 16 located at the inlet to make the airflow uniform.

[0070] (2) The flue gas flowing through the first guide device 16 enters the acid gas removal device 11, where it reacts with quicklime and circulating ash transported by the material circulation channel L1 to remove most of the strong acid gas.

[0071] (3) The flue gas flowing through the acid gas removal device 11 is accelerated by the Venturi acceleration device 17.

[0072] (4) The accelerated flue gas enters the multi-pollutant synergistic removal device 12. The flue gas with a high flow rate can achieve more sufficient gas-solid contact in the multi-pollutant synergistic removal device 12. Pollutants such as heavy metals, dioxins, and SO2 are removed in the multi-pollutant synergistic removal device 12 by quicklime and other additives (such as activated carbon).

[0073] (5) The flue gas after passing through the multi-pollutant synergistic removal device 12 enters the dust removal device 13 through the air inlet below the dust removal device 13. The upper part of the dust removal device 13 is equipped with filter bags 1312 and pulse cleaning machine 1314, and the lower part is equipped with ash hopper 1311. Part of the dust in the flue gas falls into the ash hopper 1311 by gravity, and the rest is separated on the surface of the filter bags 1312. When the dust on the surface of the filter bags 1312 reaches a certain pressure difference, the pulse cleaning machine 1314 is activated to clean the dust on the surface of the filter bags 1312 into the ash hopper 1311. Part of the dust in the ash hopper 1311 containing unreacted absorbent returns to the acid gas removal device 11 through the material circulation channel L1 to participate in the continued reaction, while the other part is discharged through the external ash discharge channel L2.

[0074] (6) The flue gas passing through the dust removal device 13 enters the denitrification device 14 through the second flow guiding device 18, so that the flue gas can pass evenly through the catalyst layer in the denitrification device 14 to carry out the denitrification reaction and generate purified flue gas.

[0075] (7) The purified flue gas is transported to the chimney by the induced draft fan and then discharged into the atmosphere.
