Description

Technical Field

[0001] The utility model relates to the technical field of flue gas treatment, in particular to a flue gas mercury removal device. Background Art

[0002] Flue gas containing mercury is usually generated during the production process in thermal power generation, steel, chemical industry and other fields. Mercury is a highly toxic and persistent harmful substance. In order to avoid the harm of mercury to the environment and human health, the flue gas needs to be demercured when it is discharged.

[0003] In actual treatment processes, using activated carbon to absorb mercury from flue gas is a common method for removing mercury. Activated carbon plates are typically installed in the demercuration device. As flue gas passes through the activated carbon plates, they absorb mercury from the flue gas. However, after long-term use, the activated carbon plates become saturated, reducing their adsorption efficiency. This often necessitates pausing the demercuration device and removing the activated carbon plates for desorption. While the activated carbon plates are being replaced, the demercuration device becomes inoperable, reducing efficiency. Therefore, this application proposes a flue gas demercuration device that can be replaced with activated carbon without shutting down. Utility Model Content

[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0027] The utility model discloses a flue gas mercury removal device, comprising:

[0028] A treatment unit 1 for removing mercury from flue gas includes a gas pipe 11 for conveying the flue gas. The inlet of the gas pipe 11 is used to receive the flue gas. A fan 12 is provided at the outlet of the gas pipe 11. The fan 12 is used to guide the flue gas out of the outlet of the gas pipe 11. The gas pipe 11 is also provided with a filter 13, which is arranged on a side of the fan 12 away from the outlet of the gas pipe 11.

[0029] The conveying component 2 is provided on one side of the processing component 1, and one end of the conveying component 2 is connected to the air delivery pipe 11. The conveying component 2 is used to spray the granular activated carbon into the air delivery pipe 11;

[0030] The collecting component 3 is arranged below the gas pipe 11, and one end of the collecting component 3 is connected to the gas pipe 11. The collecting component 3 is used to collect saturated adsorbed granular activated carbon. The above-mentioned filter 13 is used to prevent the activated carbon from being discharged from the gas pipe 11 together with the flue gas.

[0031] In a specific implementation, the flue gas is first transported from the inlet of the gas pipe 11 into the gas pipe 11. The fan 12 is started and guides the flue gas in the gas pipe 11 toward the outlet of the gas pipe 11. At this time, the conveying component 2 conveys granular activated carbon into the gas pipe 11. The activated carbon contacts the flue gas and flows with the flue gas. When the activated carbon contacts the flue gas, it adsorbs mercury in the flue gas until the activated carbon passes through the collection component 3. The collection component 3 collects and stores the activated carbon. At this time, the activated carbon content in the flue gas decreases and continues to flow in the gas pipe 11 until the flue gas passes through the filter 13 and is discharged from the gas pipe 11. When the flue gas passes through the filter 13, the filter 13 prevents the activated carbon mixed in the flue gas from leaving the gas pipe 11 with the flue gas. The activated carbon collected in the collection component 3 can then be sent to a heating device for thermal decomposition. After the thermal decomposition is completed, the activated carbon is re-transported to the conveying component 2.

[0032] In the present invention, the flue gas and the granular activated carbon are fully contacted in the gas pipe 11 by cooperating with the conveying component 2, thereby removing mercury from the flue gas. The activated carbon saturated with adsorption is collected by the collecting component 3 and recycled, and the treated activated carbon is transported to the conveying component 2 again. The entire working process does not require equipment shutdown, thereby improving work efficiency.

[0033] In one embodiment, the gas delivery pipe 11 is provided with a "J"-shaped curved pipe section 111 near the outlet;

[0034] The collecting component 3 includes a first collecting bin 31 arranged at the bottom of the bend section 111, the inner cavity of the first collecting bin 31 is communicated with the bottom of the bend section 111, and a first supporting plate 32 is rotatably provided in the first collecting bin 31. The first supporting plate 32 is used to open or close the bottom of the first collecting bin 31. A torsion spring (not shown in the figure) is provided at the rotation connection between the first collecting bin 31 and the first supporting plate 32. The torsion spring applies a torsion force for the first supporting plate 32 to rotate upward. The second collecting bin 33 is also vertically arranged. The top of the second collecting bin 33 passes through the air supply pipe 11, and the inner cavity of the second collecting bin 33 is communicated with the cavity of the air supply pipe 11. The filter 13 is arranged in the second collecting bin The connection point between the bin 33 and the gas pipe 11, the fan 12 is arranged at the outlet of the curved pipe section 111, the second collecting bin 33 is used to collect the activated carbon intercepted by the filter 13, and a second supporting plate 34 is rotatably provided in the second collecting bin 33. The second supporting plate 34 is used to open or close the bottom of the second collecting bin 33. Another torsion spring (not shown in the figure) is provided at the rotating connection between the second collecting bin 33 and the second supporting plate 34. The torsion spring applies a torque to the second supporting plate 34 to rotate upward, and also includes a storage component 35 connected to the bottom ends of the first collecting bin 31 and the second collecting bin 33 respectively, and the storage component 35 is used to store the activated carbon in the first collecting bin 31 and the second collecting bin 33.

[0035] With this design, when the flue gas carrying the activated carbon passes through the bend section 111, each torsion spring drives the corresponding supporting plate to rotate upward, and each supporting plate closes the corresponding collecting bin. The airflow guides the flue gas to move toward the outlet of the gas pipe 11, and the activated carbon falls on the first supporting plate 32 under the influence of gravity. As the gas pipe 11 continues to work, the activated carbon on the first supporting plate 32 gradually accumulates until the gravity of the activated carbon on the first supporting plate 32 is greater than the torsion of the torsion spring at the rotation connection between the first collecting bin 31 and the first supporting plate 32. At this time, the first supporting plate 32 rotates downward, the bottom of the first collecting bin 31 opens, the corresponding torsion spring is compressed, and the activated carbon on the first supporting plate 32 falls into the storage component. When When the gravity of the activated carbon on the first supporting plate 32 is less than the torsion force of the corresponding torsion spring, the corresponding torsion spring drives the first supporting plate 32 to rotate upward, and the bottom of the first collecting bin 31 is closed. When the smoke passes through the filter 13, the activated carbon in the smoke that does not fall into the first collecting bin 31 is intercepted by the filter 13 and falls onto the second supporting plate 34. When the activated carbon on the second supporting plate 34 accumulates to an appropriate amount, the torsion spring on the second supporting plate 34 is compressed and causes the second supporting plate 34 to rotate downward, and the activated carbon on the second supporting plate 34 falls into the storage component. When there is not enough weight of activated carbon on the second supporting plate 34, the corresponding torsion spring drives the second supporting plate 34 to rotate upward, and the second collecting bin 33 is closed.

[0036] In one embodiment, the storage assembly 35 includes a storage bin 351 arranged below the gas pipe 11, the bottom ends of the first collection bin 31 and the second collection bin 33 are connected to the storage bin 351, and the inner cavities of the first collection bin 31 and the second collection bin 33 are connected to the inner cavity of the storage bin 351, and a storage cabinet 352 is also slidably inserted in the storage bin 351. When the storage cabinet 352 is inserted in the storage bin 351, the storage cabinet 352 is used to store and transfer the activated carbon collected in the first collection bin 31 and the second collection bin 33.

[0037] With this design, when the first supporting plate 32 and the second supporting plate 34 rotate downward, the activated carbon on the first supporting plate 32 and the second supporting plate 34 falls into the storage cabinet 352. When there is enough activated carbon stored in the storage cabinet 352, the staff will pull the storage cabinet 352 out of the storage bin 351 and transfer the activated carbon to the heating device for thermal analysis processing.

[0038] In one embodiment, a cleaning component 4 is provided on the second collecting bin 33, and the cleaning component 4 includes a first power unit 41 arranged on the top of the second collecting bin 33. The moving end of the first power unit 41 is vertically inserted into the chamber of the second collecting bin 33 and is provided with a scraper 42. The scraping surface of the scraper 42 is in contact with the filtering surface of the filter 13. When the first power unit 41 drives the scraper 42 to move vertically back and forth, the scraper 42 is used to scrape off the activated carbon attached to the filter 13. A gathering component 43 is also provided on the moving end of the first power unit 41. When the scraper 42 cleans the filter 13, the gathering component 43 is used to collect the activated carbon scraped by the scraper 42.

[0039] With this design, when the filter 13 intercepts the activated carbon in the flue gas, part of the activated carbon will adhere to the filter 13. To prevent the filter 13 from being blocked, the first power unit 41 drives the scraper 42 and the gathering component 43 to move downward together. When the scraper 42 moves, it contacts the filtering surface of the filter 13 and scrapes off the activated carbon attached to the filter 13. The gathering component 43 collects the activated carbon scraped off by the scraper 42 to prevent the activated carbon from being affected by the airflow blown by the fan 12 and adhering to the filter 13 again, until the scraper 42 moves to the bottom of the filter 13. At this time, the airflow no longer interferes with the activated carbon at the gathering component 43, and the activated carbon falls onto the second supporting plate 34 due to gravity.

[0040] Preferably, the first power unit 41 may be a cylinder in the prior art.

[0041] In one embodiment, the aggregation assembly 43 includes a collection cover 431 arranged on the moving end of the first power unit 41. The side of the collection cover 431 close to the filter 13 is connected to the scraper 42, and the other side surfaces are fitted with the corresponding side surfaces in the inner cavity of the second collection bin 33. When the collection cover 431 moves downward, the collection cover 431 is used to prevent the activated carbon scraped off by the scraper 42 from diffusing upward.

[0042] With this design, when the first power unit 41 drives the scraper 42 and the collecting cover 431 to move downward, the scraper 42 will scrape off the activated carbon attached to the filter 13, and the collecting cover 431 will gather the scraped activated carbon together and drive the activated carbon to move downward, thereby avoiding the activated carbon floating near the filter 13 from diffusing upward and attaching to the filter 13 again due to the influence of the airflow of the fan 12.

[0043] In one embodiment, the conveying component 2 includes a storage box 21 arranged on one side of the inlet of the gas pipe 11, and granular activated carbon is stored in the storage box 21. A conveying pipe 22 is also provided above the storage box 21. The inlet of the conveying pipe 22 is inserted in the storage box 21, and the outlet of the conveying pipe 22 is inserted in the gas pipe 11. The conveying pipe 22 is used to convey the activated carbon to the gas pipe 11. A second power unit 23 is also provided at the top of the storage box 21. The second power unit 23 is connected to the conveying pipe 22. The second power unit 23 is used to provide power for the conveying pipe 22 when conveying activated carbon.

[0044] With this design, when the activated carbon needs to be transported into the gas pipe 11 , the second power unit 23 is started, the second power unit 23 introduces the activated carbon into the delivery pipe 22 , and moves the activated carbon in the delivery pipe 22 until it is discharged from the outlet of the delivery pipe 22 .

[0045] Preferably, the second power unit 23 can adopt a wind conveyor in the prior art.

[0046] In one embodiment, a plurality of air guide strips 5 are spirally distributed on the inner wall of the gas pipe 11 , and each air guide strip 5 is used to guide the smoke and activated carbon in the gas pipe 11 to be spirally transported.

[0047] With this design, when the flue gas and activated carbon enter the gas pipe 11, the flue gas and activated carbon close to the inner wall of the gas pipe 11 rotate along the spiral direction of the air guide strip 5 and drive the flue gas and activated carbon in the gas pipe 11 away from the inner wall of the gas pipe 11 to rotate, thereby promoting the mixing of the flue gas and activated carbon in the gas pipe 11, making the activated carbon evenly filled in the flue gas, and further improving the adsorption efficiency of the activated carbon.

[0048] In one embodiment, a demisting plate 6 is provided at the inlet of the gas delivery pipe 11;

[0049] A spray component 7 is provided below the inlet of the gas pipe 11, and the spray component 7 includes a spray chamber 71 provided below the inlet of the gas pipe 11, and an air inlet 711 for introducing flue gas is provided on one side of the spray chamber 71. A liquid storage tank 72 for storing absorption medium is also provided on one side of the spray chamber 71. A third power unit 73 is also provided in the spray chamber 71, and a spray pipe 74 for spraying absorption medium is vertically provided on the output end of the third power unit 73. A plurality of spray ports are distributed on the spray pipe 74. The input end of the third power unit 73 is connected to the liquid storage tank 72. A partition plate 75 is provided between the spray pipe 74 and the third power unit 73, and the partition plate 75 is used to prevent the absorption medium from contacting the third power unit 73.

[0050] With this design, before the flue gas is introduced into the gas pipeline 11, the flue gas first enters the spray box through the air inlet 711. At this time, the third power unit transports the absorption medium into the spray pipe 74 and sprays it out from each spray port in the form of mist. The absorption medium contacts the mercury in the flue gas and undergoes a chemical reaction to generate mercury compounds, which drip onto the partition plate 75. The flue gas that has undergone preliminary demercuration rises and passes through the demister plate 6. The demister plate 6 dehumidifies excess moisture in the flue gas, thereby preventing the flue gas in the gas pipeline 11 from being too wet. The mercury content in the flue gas after the preliminary demercuration is reduced, thereby extending the effective working time of the activated carbon.

[0051] Preferably, the third power unit 73 may adopt a pump in the prior art.

[0052] It should be noted that the demisting plate 6 and the spray chamber 71 are common knowledge to those skilled in the art, so their structures and functions are not described in detail here.

[0053] It should be noted that the absorption medium may be a chemical absorbent made of sodium sulfide and hydrogen sulfide.

[0054] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention. In addition, "multiple", "multiple groups", and "several" refer to more than two.
