Description

Technical Field

[0001] The present invention relates to the technical field of smoke equalization devices, and in particular to a smoke equalization device and method for desulfurization and denitrification. Background Art

[0002] In the various application environments of chemical plants, thermal power plants and steel smelters in the prior art, the main problem is that during the operation and production process of multiple equipment in the above-mentioned factories, the high-temperature flue gas generated inside the equipment contains excessive sulfur dioxide and nitrogen oxides during high-temperature operation. Therefore, the high-temperature flue gas is highly destructive to the environment, and the flue gas cannot be directly discharged into the environment. Therefore, the treatment system for desulfurization and denitrification of flue gas has been widely used in real life.

[0003] The desulfurization and denitrification system includes multiple devices for sequentially removing dust and desulfurizing and denitrifying the flue gas. The desulfurization and denitrification system is used for centralized dust removal and desulfurization of the flue gas produced by multiple devices in the factory. However, in actual use, the flue gas flow rate, flue gas temperature, conveying pressure and dust, sulfur dioxide and nitrogen oxide content in the flue gas produced by different equipment are quite different. When performing dust removal and desulfurization and denitrification operations, the power parameters of the dust removal equipment and the desulfurization tower will be adjusted to a relatively stable value. However, if there are large deviations in the flue gas conveying speed, temperature and impurity content, it will not only affect the desulfurization and denitrification effect of the flue gas, but also cause a waste of resources used for desulfurization and denitrification of the flue gas.

[0018] A method for equalizing smoke for desulfurization and denitrification, using the above-mentioned device for equalizing smoke for desulfurization and denitrification, comprises the following steps:

[0019] The working principle and beneficial effects of the present invention are:

[0020] In the present invention, when flue gas containing sulfur dioxide and nitrogen oxides is generated in multiple production equipment, in order to perform optimized desulfurization and denitrification treatment operations on the flue gas generated in multiple production equipment, it is necessary to maintain the same flow rate, temperature and impurity content of the flue gas generated by multiple production equipment when transported to the desulfurization tower, to ensure that the desulfurization tower performs good treatment operations on flue gases with little difference. During the use of the present invention, the flue gas exhaust channels of multiple equipment are kept connected to the flue gas conveying pipe, and then the flue gas is conveyed toward the uniform chimney body through the flue gas conveying pipe. After entering the uniform chimney body, multiple flue gases are mixed, and after being discharged through multiple exhaust holes, the flue gas is discharged evenly from the uniform chimney body, so that the flue gas enters the desulfurization and denitrification equipment evenly.

[0021] In the present invention, during the process of conveying different flue gases from the flue gas conveying pipes, when the flue gas flow rate or impurity content conveyed in any two flue gas conveying pipes is greatly different, in order to maintain the same conveying flow rate and impurity content of the flue gases between the two flue gas conveying pipes, the flue gases in the two flue gas conveying pipes are conveyed into the interconnected cylinder, and under the action of the rotating connecting component, the two flue gas conveying pipes are kept connected, and the flue gas in the flue gas conveying pipe with high pressure will flow into the flue gas conveying pipe with low pressure, thereby achieving mixing of the two flue gases, which is convenient for subsequent desulfurization and denitrification equipment to achieve good desulfurization effect on the flue gas.

[0022] In the present invention, when the flue gas in the flue gas conveying pipeline has a relatively high temperature during the conveying process, the desulfurization and denitrification equipment in the prior art usually uses the technical method of spraying desulfurization liquid to desulfurize and denitrify the flue gas. In order to ensure the effect of the desulfurization liquid on the flue gas treatment, it is necessary to ensure that the temperature difference between the flue gas and the desulfurization liquid is small. When the flue gas with a temperature higher than the desulfurization liquid circulates in the flue gas conveying pipeline, the high-temperature flue gas is selected to be conveyed into the installation cylinder, and the flue gas cooling mechanism cools the flue gas before conveying it into the uniform flue cylinder. Or when the flue gas in other flue gas conveying pipelines is slightly higher than the desulfurization liquid, the cooled flue gas can be selected to be conveyed into the flue gas conveying pipeline to mix the two flue gases, balance the temperature of the flue gas in the flue gas conveying pipeline, and ensure the working effect of the subsequent desulfurization and denitrification equipment.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0034] Example 1, as Figures 1 to 7As shown, this embodiment proposes a smoke uniforming device for desulfurization and denitrification, including a fixed support tube 1, the top of the fixed support tube 1 is fixedly connected with a smoke uniforming tube body 2, and the top of the smoke uniforming tube body 2 is provided with multiple smoke exhaust holes to transport multiple flue gases into the smoke uniforming tube body 2, and the multiple smoke exhaust holes are distributed in a circle on the top of the smoke uniforming tube body 2, so that after the multiple flue gases are mixed, the flue gases are discharged through the multiple smoke exhaust holes. During use, the smoke uniforming tube body 2 is usually set at the bottom of the inlet and outlet of the desulfurization and denitrification equipment to make the flue gas enter the desulfurization and denitrification equipment evenly.

[0035] It also includes a flue gas conveying pipe 3, the number of which is set to be multiple, and the multiple flue gas conveying pipes 3 are all arranged in the fixed support tube 1. The top of the flue gas conveying pipe 3 is connected to the flue tube body 2. It also includes a support seat 7, and the bottom of the fixed support tube 1 is fixedly connected to the support seat 7. The bottoms of the multiple flue gas conveying pipes 3 are all fixedly connected to the support seat 7. The support seat 7 is used to support the fixed support tube 1 and the flue gas conveying pipe 3, and to protect the bottom of the flue gas conveying pipe 3.

[0036] An interconnecting cylinder 4 is provided in the middle parts of multiple flue gas conveying pipes 3, and a rotating communication mechanism 100 is provided in the interconnecting cylinder 4. The rotating communication mechanism 100 is used to connect any two flue gas conveying pipes 3. The rotating communication mechanism 100 includes an annular sleeve 8, a rotating cylinder 9 and a movable communication component. The annular sleeve 8 is fixedly connected in the interconnecting cylinder 4, and the rotating cylinder 9 is rotatably arranged in the annular sleeve 8 through the rotating component. The rotating component includes a driving rotating shaft 12 and a driving motor 13. The bottom of the fixed support cylinder 1 passes through the driving rotating shaft 12 for rotation. The driving motor 13 is provided on the support seat 7. The output end of the driving motor 13 is fixedly connected to the driving rotating shaft 12. When it is necessary to adjust the rotation angle of the rotating cylinder 9 so that one of the mobile inserts 15 corresponds to the flue gas conveying pipe 3 with higher pressure, the driving motor 13 is started to drive the driving rotating shaft 12 to rotate, so that the rotating cylinder 9 adjusts its position along the center point of the driving rotating shaft 12.

[0037] A movable communication component is provided in the rotating cylinder 9, and the movable communication component includes a fixed cylinder 14, a movable plug cylinder 15 and a double-headed electric cylinder 17. The fixed cylinder 14 is fixedly connected to the inside of the rotating cylinder 9, and movable plug cylinders 15 are slidably provided on both sides of the rotating cylinder 9. A communicating hose 16 is connected between the movable plug cylinder 15 and the fixed cylinder 14. A double-headed electric cylinder 17 is provided on the rotating cylinder 9, and the output end of the double-headed electric cylinder 17 is fixedly connected to the movable plug cylinder 15, wherein an embedding groove is provided on the side of the movable plug cylinder 15 close to the communicating interface 10, and a sealing ring sleeve 18 is provided in the embedding groove. After one of the movable plug cylinders 15 corresponds to the flue gas conveying pipe 3 with higher pressure, the double-headed electric cylinder 17 is started to drive the two movable plug cylinders 15 to move in the rotating cylinder 9, so that one side of the movable plug cylinder 15 enters the communicating interface 10, and the sealing ring sleeve 18 is tightly fitted with the inner wall of the communicating interface 10, so that the two corresponding communicating interfaces 10 maintain communication;

[0038] A communication interface 10 is connected to the flue gas conveying pipe 3, and the communication interface 10 passes through the interconnecting cylinder 4. An inlet is opened on the inner arc surface of the annular sleeve 8 corresponding to the communication interface 10, and a valve is provided on the communication interface 10. A transfer pipeline 11 is connected between two adjacent communication interfaces 10, and a valve is also provided on the transfer pipeline 11. When it is necessary to maintain communication between two flue gas conveying pipes 3 that are perpendicular to each other with the driving rotating shaft 12 as the center, after the valve on the communication interface 10 is opened in the flue gas conveying pipe 3 with higher pressure, the flue gas will pass through the fixed cylinder 14 and enter the communication interface 10 on the other side, but the communication interface 10 on the other side remains closed, so that the flue gas will not enter the corresponding flue gas conveying pipe 3. At this time, the valve on the corresponding transfer pipeline 11 is opened again to allow the flue gas to enter the corresponding communication interface 10 and allow the flue gas to enter the corresponding flue gas conveying pipe 3 for transportation together, so as to facilitate the adjustment of the flue gas conveying pressure in the high-pressure flue gas conveying pipe 3 and compensate for the flue gas conveying speed in the flue gas conveying pipe 3 with lower pressure.

[0039] Each flue gas conveying pipe 3 is provided with a partition conveying assembly 200, which includes a partition cylinder 19. The partition cylinder 19 is fixedly connected to the flue gas conveying pipe 3, and a partition plate 20 is fixedly connected to the middle of the partition cylinder 19. The partition plate 20 divides the partition cylinder 19 into two gas delivery chambers. The upper and lower sides of the gas delivery chamber are connected to gas delivery interfaces 21, and valves are also provided on the gas delivery interfaces 21. One of the gas delivery chambers is connected to a delivery interface 31. In order to transport the high-temperature flue gas to the installation cylinder 5 for cooling, after opening the valve of the gas delivery interface 21 on the lower side, the high-temperature flue gas enters the two gas delivery chambers, and then the valve of the gas delivery interface 21 on the top of the gas delivery chamber connected to the delivery interface 31 is closed, so that the high-temperature flue gas enters the installation cylinder 5 through the delivery interface 31;

[0040] The installation cylinder 5 is communicated with a plurality of partition conveying components 200, a flue gas cooling mechanism 300 is provided in the installation cylinder 5, the flue gas cooling mechanism 300 is communicated with the smoke uniforming cylinder 2, a return pipe 6 is provided between the flue gas cooling mechanism 300 and the flue gas conveying pipe 3, the flue gas cooling mechanism 300 includes an annular support frame 22, a heat sink 24, a heat dissipation fin 25, a water supply component, a conveying flue 26 and a drain pipe 27, an annular support frame 22 is fixedly connected to the installation cylinder 5, a flexible expansion cylinder 23 is provided in the annular support frame 22, the flexible expansion cylinder 23 is communicated with the conveying interface 31, a plurality of grooves are provided at the bottom of the flexible expansion cylinder 23, a heat sink 24 is fixedly connected between the groove and the installation cylinder 5, a plurality of heat dissipation fins 25 are fixedly connected to the inner top wall of the installation cylinder 5, a sloped slide groove is provided in the heat dissipation fin 25, a water supply is provided on the top of the installation cylinder 5 Component, a conveying flue 26 is connected between the top of the flexible expansion cylinder 23 and the smoke distribution cylinder 2, and a return pipe 6 is connected to the conveying flue 26. A valve is also provided on the return pipe 6. The bottom of the installation cylinder 5 is connected to a drain pipe 27. The drain pipe 27 runs through the fixed support cylinder 1. When it is necessary to cool the high-temperature flue gas, the high-temperature flue gas is first transported to the flexible expansion cylinder 23. After a sufficient amount of flue gas enters the flexible expansion cylinder 23, the flexible expansion cylinder 23 will expand. The outer wall of the flexible expansion cylinder 23 will contact the heat sink 24 and the heat dissipation fins 25, and the heat of the high-temperature flue gas will be transferred to the heat sink 24 and the heat dissipation fins 25. Because after the flexible expansion cylinder 23 is inflated and expanded, the heat sink 24 and the heat dissipation fins 25 will sink into the flexible expansion cylinder 23, thereby facilitating the heat transfer of the high-temperature flue gas inside the flexible expansion cylinder 23.

[0041] The cooled flue gas is transported to the smoke distribution tube body 2 through the conveying flue 26, and by opening the valve on the corresponding return pipe 6, the cooled flue gas is transported to the corresponding flue gas conveying pipe 3 through the return pipe 6, in order to replenish the flue gas in the flue gas conveying pipe 3 or balance the flue gas temperature in the flue gas conveying pipe 3.

[0042] Water is supplied to the installation cylinder 5 through the water supply component, so that the water flows downward along the sloped groove in the heat dissipation fins 25, thereby improving the heat dissipation effect of the heat dissipation fins 25, and the heat dissipation fins 24 are immersed in the cooling water, so that the heat dissipation fins 24 can fully dissipate the high temperature in the flexible expansion cylinder 23. After the cooling water in the installation cylinder 5 is heated, it is discharged through the drain pipe 27.

[0043] The water supply assembly includes an annular water supply cylinder 28 and a drainage head 30. The annular water supply cylinder 28 is arranged at the top of the mounting cylinder 5. The annular water supply cylinder 28 is connected to a water supply pipe 29. The bottom of the annular water supply cylinder 28 is connected to multiple drainage heads 30. The drainage heads 30 correspond one-to-one to the heat dissipation fins 25. Water is injected into the annular water supply cylinder 28 through the water supply pipe 29, and the cooling water is discharged through the multiple drainage heads 30 to the upper side of the heat dissipation fins 25 in the mounting cylinder 5, so that the cooling water cools the flue gas in the flexible expansion cylinder 23.

[0044] The working principle of the smoke equalization device for desulfurization and denitrification:

[0045] First, the smoke exhausted by multiple devices is transported to the corresponding smoke conveying pipe 3, and then the smoke is transported upward in the smoke conveying pipe 3. Then, the driving motor 13 is started to drive the driving rotating shaft 12 to rotate, so that the rotating cylinder 9 is adjusted along the center point of the driving rotating shaft 12. After one of the mobile plug-ins 15 corresponds to the smoke conveying pipe 3 with higher pressure, the double-headed electric cylinder 17 is started to drive the two mobile plug-ins 15 to move in the rotating cylinder 9, so that one side of the mobile plug-in 15 enters the connecting interface 10, and the sealing ring sleeve 18 is connected to the connecting interface 10. The inner walls of the communication ports 10 fit tightly together, so that the two corresponding communication ports 10 remain connected. When the valve on the communication port 10 of the flue gas conveying pipe 3 with higher pressure is opened, the flue gas will pass through the fixed cylinder 14 and enter the communication port 10 on the other side. However, the communication port 10 on the other side remains closed, so that the flue gas will not enter the corresponding flue gas conveying pipe 3. At this time, the valve on the corresponding transfer pipeline 11 is opened to allow the flue gas to enter the corresponding communication port 10 and the corresponding flue gas conveying pipe 3 for transportation together.

[0046] In order to transport the high-temperature flue gas into the installation cylinder 5 for cooling, after opening the valve of the gas supply interface 21 at the lower side, the high-temperature flue gas enters the two gas supply chambers, and then closes the valve of the gas supply interface 21 at the top of the gas supply chamber connected to the delivery interface 31, so that the high-temperature flue gas enters the flexible expansion cylinder 23 through the delivery interface 31. After a sufficient amount of flue gas enters the flexible expansion cylinder 23, the flexible expansion cylinder 23 will expand, and the outer wall of the flexible expansion cylinder 23 will contact the heat sink 24 and the heat sink fins 25, transferring the heat of the high-temperature flue gas to the heat sink 24 and the heat sink fins 25. Because after the flexible expansion cylinder 23 is inflated and expanded, the heat sink 24 The cooling fins 25 will be sunken into the flexible expansion cylinder 23, thereby facilitating the transfer of heat from the high-temperature flue gas inside the flexible expansion cylinder 23. Water is injected into the annular water supply cylinder 28 through the water supply pipe 29, and the cooling water is discharged through multiple drainage heads 30 to the upper side of the cooling fins 25 in the installation cylinder 5, so that the cooling water cools the flue gas in the flexible expansion cylinder 23. The cooled flue gas is then transported to the flue cylinder 2 through the conveying flue 26, and by opening the valve on the corresponding return pipe 6, the cooled flue gas is transported to the corresponding flue gas conveying pipe 3 through the return pipe 6 to replenish the flue gas in the flue gas conveying pipe 3 or balance the flue gas temperature in the flue gas conveying pipe 3.

[0047] In the second embodiment, the present invention is based on a smoke equalization device for desulfurization and denitrification, and also proposes a smoke equalization method for desulfurization and denitrification, which specifically includes the following steps:

[0048] Step 1: transporting flue gas: transporting the flue gas discharged by multiple devices into the corresponding flue gas transport pipe 3, and then transporting the flue gas upward in the flue gas transport pipe 3.

[0049] The second step is to transfer the flue gas: start the driving motor 13 to drive the driving rotating shaft 12 to rotate, so that the rotating cylinder 9 rotates along the center point of the driving rotating shaft 12, and one of the movable inserts 15 corresponds to the high-pressure flue gas conveying pipe 3. Start the double-headed electric cylinder 17 to drive the two movable inserts 15 to move in the rotating cylinder 9, so that one side of the movable insert 15 enters the connecting interface 10, and the sealing ring sleeve 18 is tightly fitted with the inner wall of the connecting interface 10, so that the two corresponding connecting interfaces 10 are kept connected. After the valve on the connecting interface 10 is opened in the flue gas conveying pipe 3 with higher pressure, the flue gas will pass through the fixed cylinder 14 and enter the connecting interface 10 on the other side, but the connecting interface 10 on the other side remains closed, so that the flue gas will not enter the corresponding flue gas conveying pipe 3. At this time, the valve on the corresponding transfer pipeline 11 is opened again to allow the flue gas to enter the corresponding connecting interface 10 and allow the flue gas to enter the corresponding flue gas conveying pipe 3 for transportation together.

[0050] Step 3: Cooling the flue gas: Open the valve of the gas supply interface 21 at the bottom to allow the high-temperature flue gas to enter the two gas supply chambers. Then, close the valve of the gas supply interface 21 at the top of the gas supply chamber that is connected to the delivery interface 31, allowing the high-temperature flue gas to enter the flexible expansion cylinder 23 through the delivery interface 31. After the high-temperature flue gas enters the flexible expansion cylinder 23, it will expand the flexible expansion cylinder 23, and the outer wall of the flexible expansion cylinder 23 will come into contact with the heat sink 24 and the heat dissipation fins 25, transferring the heat of the high-temperature flue gas to the heat sink 24 and the heat dissipation fins 25.

[0051] Step 4: Water injection: Water is injected into the annular water supply cylinder 28 through the water supply pipe 29, and the cooling water is discharged through the multiple drainage heads 30 to inject water into the upper side of the heat dissipation fins 25 in the installation cylinder 5, so that the cooling water cools the flue gas in the flexible expansion cylinder 23;

[0052] Step 5, flue gas recirculation: The cooled flue gas is transported to the flue gas distribution tube 2 through the delivery flue duct 26, and by opening the valve on the corresponding return pipe 6, the cooled flue gas is transported to the corresponding flue gas delivery pipe 3 through the return pipe 6 to replenish the flue gas delivery pipe 3 or balance the flue gas temperature in the flue gas delivery pipe 3;

[0053] Step 6: Smoke distribution: eventually, the smoke in the smoke delivery duct 26 and the multiple smoke delivery pipes 3 maintains a similar flow rate to enter the smoke distribution cylinder 2, and is finally discharged through the multiple smoke exhaust holes on the smoke distribution cylinder 2.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
