DETAILED DESCRIPTION
[0028] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.
[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.
[0030] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.
[0031] Example:
[0032] like Figure 1-Figure 3 As shown, the flue gas treatment device provided in this embodiment includes a desulfurization component and a decarbonization component; the desulfurization component includes a desulfurization chamber 1, and the decarbonization component includes a decarbonization chamber 2. The desulfurization chamber 1 and the decarbonization chamber 2 are both provided with an air inlet and an air outlet, and the air outlet of the desulfurization chamber 1 is connected to the air inlet of the decarbonization chamber 2; the desulfurization chamber 1 is used to hold the sulfur treatment solution; the decarbonization chamber 2 is provided with a dispersion member 3 and an adsorption member 4, and the dispersion member 3 is provided between the air inlet and the air outlet of the decarbonization chamber 2, and is used to divide the decarbonization chamber 2 into an air inlet chamber and a treatment chamber; as shown Figure 4 As shown, the dispersion component 3 is provided with a plurality of air equalization holes 30 connecting the air inlet chamber and the processing chamber. The adsorption component 4 is arranged in the processing chamber and faces the dispersion component 3. The adsorption component 4 is used to adsorb carbon-containing gas in the gas entering the processing chamber.
[0033] The flue gas treatment device provided in this embodiment is used for desulfurization of sulfur-containing gases in flue gas, and for emission reduction of carbon-containing gases in flue gas, such as sulfur oxides and carbon-containing gases such as carbon dioxide.
[0034] When using the flue gas treatment device to treat flue gas, the flue gas can be first passed into the desulfurization chamber 1 through the air inlet of the desulfurization chamber 1. At this time, the flue gas will flow into the sulfur treatment solution (alkaline solution) contained in the desulfurization chamber 1 and react with it to achieve the desulfurization effect. After desulfurization treatment, the flue gas will continue to flow and enter the air inlet cavity of the decarbonization chamber 2 through the air outlet of the desulfurization chamber 1 and the air inlet of the decarbonization chamber 2. In the decarbonization chamber 2, the detached flue gas will first reach the air inlet cavity, and then pass through the multiple air equalization holes 30 on the dispersion component 3 to flow to the treatment cavity, and then the carbon-containing gases such as carbon dioxide in the flue gas are adsorbed by the adsorption component 4 to achieve the decarbonization effect.
[0035] It should be noted that the flue gas will be dispersed when passing through the air equalizing holes 30 on the dispersion component 3. When the flue gas reaches the adsorption component 4 in the treatment chamber, the flue gas is more evenly distributed and contacts the adsorption component 4 more fully, thereby effectively improving the treatment effect of the adsorption component 4 on carbon dioxide and other carbon-containing gases.
[0036] It should also be noted that since the flue gas treatment device can perform decarbonization treatment on the flue gas after desulfurization treatment, the device can integrate desulfurization treatment and carbon dioxide emission reduction on the same device and perform them successively. It has a compact structure and a high degree of integration. There is no need to carry out the desulfurization process and decarbonization process separately on two independent devices, which effectively improves the flue gas treatment efficiency.
[0037] Compared to existing technologies, the flue gas treatment device provided in this embodiment integrates the desulfurization and decarbonization processes into the same device by connecting the gas outlet of the desulfurization chamber 1 with the gas inlet of the decarbonization chamber 2. This allows desulfurization and carbon dioxide emission reduction to be performed sequentially, eliminating the need for separate treatments in two independent devices, effectively improving flue gas treatment efficiency. Furthermore, the flue gas treatment device can evenly distribute the gas entering the decarbonization chamber 2 through the dispersion element 3, thereby increasing the contact area between the flue gas and the adsorption element 4 and effectively improving the carbon dioxide treatment effect.
[0038] like Figure 4 As shown, in order to further enhance the air uniformity effect of the dispersion member 3 on the flue gas, the multiple air uniformity holes 30 on the dispersion member 3 can be distributed at equal intervals.
[0039] In order to allow the flue gas to flow smoothly in the desulfurization chamber 1 and the decarbonization chamber 2, the flue gas treatment device may further include an air pump for driving the flow of the flue gas.
[0040] like Figure 1 and Figure 2 As shown, a first detection structure 5 is provided at the gas outlet of the desulfurization chamber 1 , and the first detection structure 5 is used to detect the sulfur content of the gas discharged from the gas outlet of the desulfurization chamber 1 .
[0041] The first detection structure 5 detects the sulfur content of the gas discharged from the outlet of the desulfurization chamber 1 to determine whether the sulfur content of the flue gas after desulfurization meets the emission requirements. If the emission requirements are met, the flue gas can be introduced into the decarbonization chamber 2 for the next decarbonization process. If the emission requirements are not met, the flue gas can be introduced into the desulfurization chamber 1 and the desulfurization process can be repeated until the sulfur content in the flue gas meets the emission requirements.
[0042] In order to facilitate the return of flue gas whose sulfur content does not meet the emission requirements to the desulfurization chamber 1, Figure 1 and Figure 2 As shown, a first circulation pipe 6 is connected between the gas outlet and the gas inlet of the desulfurization chamber 1. The first circulation pipe 6 is used to connect the gas outlet and the gas inlet of the desulfurization chamber 1 when the sulfur content of the gas detected by the first detection structure 5 is higher than the sulfur content standard.
[0043] Further, such as Figure 1 As shown, the air inlet of the desulfurization chamber 1 can be connected to the air inlet pipe 10. At this time, one end of the first circulation pipe 6 can be connected to the air outlet of the desulfurization chamber 1, and the other end can be connected to the pipe body of the air inlet pipe 10.
[0044] like Figure 2As shown, the first detection structure 5 can include a first detector 50 and a first detection box 51, the first detection box 51 is arranged at one side of the gas outlet of the desulfurization chamber 1, and the side wall of the first detection box 51 facing the desulfurization chamber 1 is provided with an inlet, and the inlet is communicated with the gas outlet of the desulfurization chamber 1; the side wall of the first detection box 51 away from the desulfurization chamber 1 is provided with two outlets, for example, Figure 1 As shown, the first circulation pipe 6 is communicated between one of the outlets of the first detection box 51 and the gas inlet of the desulfurization chamber 1, and the other outlet of the first detection box 51 is communicated with the gas inlet of the decarburization chamber 2 through a gas conveying pipe 7; the first detector 50 is fixed on the first detection box 51, and the probe of the first detector 50 extends into the first detection box 51.
[0045] The first detector 50 is used to detect the sulfur content of the flue gas entering the first detection box 51 through the probe thereon, and the first detector 50 can adopt a concentration sensor.
[0046] In order to improve the automation degree of the flue gas treatment device, the two outlets of the first detection box 51 can be provided with electric control valves, and the electric control valves of the two outlets are communicated with the first detector 50, the two electric control valves can receive the sulfur content information detected by the first detector 50, and one of the two electric control valves is opened according to the sulfur content information. Specifically, when the sulfur content of the gas detected by the first detector 50 reaches the emission requirement, the electric control valve at the outlet of the first detection box 51 communicated with the gas conveying pipe 7 is automatically opened, thereby connecting the gas outlet of the desulfurization chamber 1 and the gas inlet of the decarburization chamber 2, so that the gas after desulfurization and reaching the emission requirement flows to the decarburization chamber 2. When the sulfur content of the gas detected by the first detector 50 does not reach the emission requirement, the electric control valve at the outlet of the first detection box 51 communicated with the first circulation pipe 6 is automatically opened, thereby connecting the gas outlet of the desulfurization chamber 1 and the gas inlet, so that the gas after desulfurization and not reaching the emission requirement flows to the desulfurization chamber 1 again.
[0047] In the embodiment, as shown in Figure 1 and Figure 3 As shown, the gas outlet of the decarburization chamber 2 can be provided with a second detection structure 8, and the second detection structure 8 is used to detect the carbon content of the gas discharged from the gas outlet of the decarburization chamber 2.
[0048] By detecting the carbon content of the gas discharged from the gas outlet of the decarburization chamber 2 through the second detection structure 8, it can be judged whether the carbon content in the gas after decarburization reaches the emission requirement. If it reaches the emission requirement, the gas can be discharged to the outside through the gas outlet of the decarburization chamber 2. Further, as shown in Figure 1 and Figure 3As shown, the gas outlet of the decarburization chamber 2 is connected to an exhaust pipe 20, and the gas is discharged to the outside through the exhaust pipe 20. If the emission requirements are not met, the gas can be introduced into the decarburization chamber 2 to restart the decarburization process until the carbon content in the decarburized gas meets the emission requirements.
[0049] It should be noted that existing flue gas treatment devices treat sulfur oxides and carbon dioxide in a single pass before directly discharging them, making it difficult to determine whether they meet the emission standards, which presents certain deficiencies. However, this embodiment, by providing a first detection structure 5 and a second detection structure 8, can separately detect the sulfur and carbon contents of the desulfurized and decarbonized gas, thereby facilitating determination of whether the gas meets the emission standards and ensuring the eligibility of flue gas emissions.
[0050] In order to facilitate the return of flue gas whose carbon content does not meet the emission requirements to the desulfurization chamber 1, Figure 1 and Figure 3 As shown, a second circulation pipe 9 can be connected between the air outlet and the air inlet of the decarburization chamber 2. The second circulation pipe 9 is used to connect the air outlet and the air inlet of the decarburization chamber 2 when the carbon content of the gas detected by the second detection structure 8 is higher than the carbon content standard.
[0051] Further, such as Figure 1 As shown, one end of the second circulation pipe 9 can be connected to the pipe body of the gas transmission pipe 7, and the other end is connected to the gas outlet of the decarbonization chamber 2.
[0052] like Figure 3 As shown, the second detection structure 8 may include a second detector 80 and a second detection box 81. The second detection box 81 is arranged on one side of the gas outlet of the decarburization chamber 2, and the side wall of the second detection box 81 facing the decarburization chamber 2 is provided with an inlet, which is connected to the gas outlet of the decarburization chamber 2; the side wall of the second detection box 81 facing away from the decarburization chamber 2 is provided with two outlets, as shown in FIG. Figure 1 As shown, the second circulation pipe 9 is connected between one of the outlets of the second detection box 81 and the pipe body of the gas supply pipe 7, and the other outlet of the second detection box 81 is connected to the exhaust pipe 20; the second detector 80 is fixed on the second detection box 81, and the probe of the second detector 80 extends into the second detection box 81.
[0053] The second detector 80 is used to detect the carbon content of the flue gas entering the second detection box 81 through the probe thereon. The second detector 80 can also be a concentration sensor.
[0054] In order to further improve the degree of automation of the flue gas treatment device, both outlets of the second detection box 81 can also be provided with electric control valves, and the electric control valves at the two outlets are connected to the second detector 80. The two electric control valves can receive the carbon content information detected by the second detector 80 and open one of them according to the carbon content information. Specifically, when the carbon content of the gas detected by the second detector 80 reaches the emission requirements, the electric control valve at the outlet of the second detection box 81 connected to the exhaust pipe 20 automatically opens, and then connects the gas outlet of the decarburization chamber 2 and the exhaust pipe 20, so that the gas that has been decarburized and has a carbon content that meets the emission requirements is discharged to the outside. When the carbon content of the gas detected by the second detector 80 does not meet the emission requirements, the electric control valve at the outlet of the second detection box 81 connected to the second circulation pipe 9 automatically opens, and then connects the gas outlet of the decarburization chamber 2 and the gas pipe 7, so that the gas that has been decarburized and has a carbon content that does not meet the emission requirements flows back to the decarburization chamber 2.
[0055] like Figure 1 As shown, a slow flow structure 11 is provided in the desulfurization chamber 1 , and the slow flow structure 11 is used to prolong the flow time of the flue gas between the air inlet and the air outlet of the desulfurization chamber 1 .
[0056] The slow flow structure 11 can prolong the residence time of the flue gas in the desulfurization chamber 1, thereby prolonging the reaction time between the sulfur oxides in the flue gas and the sulfur treatment solution (alkaline solution) in the desulfurization chamber 1, making the desulfurization more thorough.
[0057] The slow-flow structure 11 may be a wave-shaped plate structure.
[0058] Or, as Figure 1 As shown, the slow flow structure 11 includes multiple upper baffles and multiple lower baffles; from the air inlet to the air outlet of the desulfurization chamber 1, the multiple upper baffles and the multiple lower baffles are staggered in sequence, and the multiple upper baffles are fixed at intervals on the top of the desulfurization chamber 1, and the bottom of each upper baffle is spaced apart from the bottom of the desulfurization chamber 1; the multiple lower baffles are fixed at intervals on the bottom of the desulfurization chamber 1, and the top of each lower baffle is spaced apart from the top of the desulfurization chamber 1.
[0059] This arrangement allows multiple upper baffles and multiple lower baffles to be distributed in a staggered manner in the desulfurization chamber 1. Compared with the wavy plate structure, it can further extend the residence time of the flue gas in the desulfurization chamber 1, thereby further improving the desulfurization effect.
[0060] like Figure 1 As shown, the desulfurization assembly further includes a spray structure, which includes a liquid pump 12 and a plurality of nozzles 13 . The plurality of nozzles 13 are installed in the desulfurization chamber 1 and are all connected to the liquid pump 12 . The liquid pump 12 is used to supply the sulfur treatment solution to the plurality of nozzles 13 .
[0061] Among them, the liquid pump 12 is used to extract the sulfur treatment solution in the desulfurization chamber 1 and transport it to multiple nozzles 13, so that the sulfur treatment solution is sprayed through multiple nozzles 13, effectively increasing the contact area between the sulfur treatment solution and the flue gas, so that the sulfur treatment solution can fully combine with the sulfur oxides in the flue gas and react, further improving the desulfurization effect.
[0062] In order to improve the spraying effect of the sulfur treatment solution, in this embodiment, it is preferred that the multiple nozzles 13 are fixed on the top of the desulfurization chamber 1, and the multiple nozzles 13 can be distributed at equal intervals.
[0063] When the desulfurization component also includes a spray structure, such as Figure 1 As shown, the air inlet of the desulfurization chamber 1 can be arranged at a position near the top of the side wall of the desulfurization chamber 1. This arrangement makes the air inlet of the desulfurization chamber 1 close to the nozzle 13, thereby effectively shortening the distance between the flue gas and the spray solution, and further improving the desulfurization effect and desulfurization efficiency.
[0064] Further, such as Figure 1 As shown, the liquid pump 12 is arranged outside the desulfurization chamber 1, and is provided with a liquid inlet and a liquid outlet; the desulfurization chamber 1 is also provided with a liquid outlet, the liquid inlet of the liquid pump 12 is connected to the liquid outlet of the desulfurization chamber 1, and the liquid outlet of the liquid pump 12 is connected to multiple nozzles 13 through a spray pipe 14.
[0065] The liquid pump 12 is arranged outside the desulfurization chamber 1 to protect the liquid pump 12. In order to reduce the space occupied by the device, Figure 1 As shown, the liquid pump 12 can be arranged at the top of the desulfurization chamber 1 .
[0066] It should be noted that when the liquid inlet of the liquid pump 12 is connected to the liquid outlet of the desulfurization chamber 1, the liquid pump 12 can also act as a circulation pump. At this time, the liquid pump 12 can re-pump the sulfur treatment solution that falls into the desulfurization chamber 1 after spraying to multiple nozzles 13, thereby achieving the effect of recycling the sulfur treatment solution.
[0067] like Figure 1 As shown, the desulfurization chamber 1 may include a treatment chamber 15 and a precipitation chamber 16. The precipitation chamber 16 is arranged below the treatment chamber 15, and a conducting hole is provided at the bottom of the treatment chamber 15, and an opening is provided at the top of the precipitation chamber 16. The treatment chamber 15 and the precipitation chamber 16 are connected through the conducting hole and the opening.
[0068] The air inlet and outlet of the desulfurization chamber 1 can be arranged on the processing chamber 15. Correspondingly, multiple nozzles 13 and slow flow structures 11 are arranged in the processing chamber 15; the liquid outlet of the desulfurization chamber 1 is arranged on the precipitation chamber 16.
[0069] The treatment chamber 15 is used for carrying out the flue gas desulfurization process, and the sedimentation chamber 16 is used for recovering the sulfur treatment solution after spraying.
[0070] It should be noted that after the sulfur treatment solution has been recycled multiple times, to ensure the desulfurization effect, the recycled sulfur treatment solution can be discharged through a waste liquid pipe connected to the precipitation chamber 16. In this case, a liquid addition pipe can also be connected to one side of the precipitation chamber 16. After the sulfur treatment solution is discharged through the waste liquid pipe, the sulfur treatment solution can be replenished into the precipitation chamber 16 through the liquid addition pipe.
[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
