Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of desulfurization and denitrification technology, and more specifically, to a desulfurization and denitrification device with a filtration mechanism. Background Technology

[0002] Desulfurization and denitrification equipment is mainly used to remove sulfur oxides and nitrogen oxides from flue gas. The filtration mechanism is usually a part of it and is responsible for pretreatment, such as dust removal. The "filtration mechanism" in desulfurization and denitrification equipment is a key component for pretreatment of industrial flue gas. Its core function is to remove particulate matter (such as dust, fly ash, etc.) from the flue gas, so as to avoid clogging of the subsequent desulfurization and denitrification reaction device and improve the overall purification efficiency.

[0003] For dry denitrification equipment with filtration mechanisms, catalysts or packing materials are required. However, due to the presence of sticky substances such as dust and tar in the flue gas, catalysts are needed to combine with the flue gas for decomposition. The catalyst should be added according to the reaction conditions, rather than adding a large amount at once, to avoid adverse reactions between excessive catalyst and the internal flue gas. When adding catalyst, workers usually shut down the machine, turn it on, and add some catalyst particles around the perimeter of the machine. However, frequently shutting down and turning the machine on and off to add catalyst will affect the desulfurization and denitrification time, and workers who inhale the substances and odors inside the equipment directly may have health problems. Utility Model Content

Compared with the prior art, the catalyst material can be added to the tank regularly through the feeding mechanism and the dispersing mechanism, which can reduce downtime, improve the overall efficiency of desulfurization and denitrification, and reduce the time required for desulfurization and denitrification.

[0047] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0048] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0049] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0050] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0051] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0052] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0053] like Figures 1-4As shown, this embodiment of the present disclosure illustrates a desulfurization and denitrification device with a filtration mechanism, including a tank 1 and an inlet pipe 2. The inlet pipe 2 is connected to the outer wall of the tank 1. It also includes a support mechanism, a screw feeding mechanism, a dispersing feeding mechanism, a support frame 3, and a rotating distributing mechanism. The support mechanism is located at the top of the tank 1, and the screw feeding mechanism is mounted on the support mechanism. The support mechanism supports the screw feeding mechanism, which is used to feed catalyst material into the tank 1. The dispersing feeding mechanism is located at the bottom of the screw feeding mechanism, which disperses the material from the screw feeding mechanism into the tank 1. The support frame 3 is fixedly connected to the top of the support mechanism, and a storage mechanism is located at the top of the support frame 3, which supports the storage mechanism and stores catalyst material. The rotating distributing mechanism is mounted on the storage mechanism, which dispenses the catalyst material into the storage mechanism in stages. Four supports 6 are fixedly connected to the bottom of the tank 1, which support the tank 1 for desulfurization and denitrification filtration.

[0054] It should be added that the interior of tank 1 includes a spray layer and a packing layer. After the worker adds the catalyst material from the top of tank 1, the catalyst material will first pass through the spray layer to be evenly sprayed into the flue gas. After the flue gas enters from the inlet pipe 2, it passes through the packing layer to increase the contact area between the flue gas and the catalyst material. At this time, the flue gas passing through the packing layer will be filtered.

[0055] In this embodiment, the support mechanism includes a fixed frame 101, support rods 102 and a support plate 103. The fixed frame 101 is fixedly connected to the top of the tank 1, and the support frame 3 is fixedly connected to the top of the fixed frame 101. Four support rods 102 are fixedly connected to the inner wall of the fixed frame 101 near the top, and the support plate 103 is fixedly connected between the four support rods 102.

[0056] In this embodiment, the spiral feeding mechanism includes a funnel 201, a motor 202, a rotating shaft 203, and a spiral blade 204. The funnel 201 is fixedly connected to the inner wall of the fixed frame 101 near the bottom. The motor 202 is installed on the top of the support plate 103. The rotating shaft 203 is fixedly connected to the output end of the motor 202. The spiral blade 204 is fixedly connected to the outer wall of the rotating shaft 203.

[0057] In this embodiment, the dispersing feeding mechanism includes a connecting shaft 301, a rotating plate 302, and a partition plate 303. The connecting shaft 301 is fixedly connected to the end of the rotating shaft 203 away from the motor 202. The bottom of the connecting shaft 301 is fixedly connected to the rotating plate 302, and the top of the rotating plate 302 is fixedly connected to four partition plates 303. The top of the partition plate 303 is set as an arc surface 4, and the top of the rotating plate 302 is set as a slope surface 5. All of these are to avoid the catalyst material from clogging and accumulating when it is stored in the tank 1, making it difficult to discharge normally downwards.

[0058] In this embodiment, the storage mechanism includes a fixed plate 401, a discharge port 402, a storage pipe 403, and a rotating groove 404. The fixed plate 401 is fixedly connected to the top of the support frame 3. The top of the fixed plate 401 has a discharge port 402. The top of the fixed plate 401 is connected to the storage pipe 403. One end of the storage pipe 403 passes through the fixed plate 401 and extends into the support frame 3. A rotating groove 404 is provided on the outer wall of the storage pipe 403 near the top of the fixed plate 401. The end of the storage pipe 403 that extends into the support frame 3 is located between two support rods 102. The purpose is to prevent the catalyst material from being blocked by the support rods 102 when it is being fed.

[0059] In this embodiment, the rotating material distribution mechanism includes a second motor 501, a rotating rod 502, a first rotating plate 503, and a second rotating plate 504. The second motor 501 is mounted on the top of the fixed plate 401. The rotating rod 502 is fixedly connected to the output end of the second motor 501. The first rotating plate 503 is fixedly connected to the outer wall of the rotating rod 502 near its top. The second rotating plate 504 is fixedly connected to the outer wall of the rotating rod 502 near the second motor 501. The first rotating plate 503 is pressed against the top of the rotating groove 404, and the second rotating plate 504 is pressed against the top of the rotating groove 404. At the bottom of 04, rotating vane 1 503 and rotating vane 2 504 are connected in a relative position. The purpose is that when the motor 2 501 drives rotating vane 1 503 and rotating vane 2 504 to rotate, when rotating vane 1 503 opens the rotating trough 404, the catalyst material will first fall onto rotating vane 2 504. Then, when rotating vane 1 503 closes the rotating trough 404 again, rotating vane 2 504 will open the rotating trough 404, at which time the catalyst material will be discharged into tank 1 through storage pipe 403.

[0060] In this embodiment, during flue gas desulfurization and denitrification, the operator first places the catalyst material in the storage pipe 403 before starting the desulfurization and denitrification process. Then, the flue gas flows into the tank 1 through the inlet pipe 2. At this time, motor 2 501 is started, driving the rotating rod 502 to rotate. Rotating discs 1 503 and 2 504, fixedly connected to the rotating rod 502, will rotate. When rotating discs 1 503 and 2 504 exchange positions, the catalyst material in the storage pipe 403 falls onto the top of rotating disc 2 504. Upon further rotation, rotating disc 1 503 blocks the catalyst material at its top, and the material on top of rotating disc 2 504 flows through the storage pipe 403 into the funnel 201. At this point, motor 1 202 can be started. Motor 202 drives shaft 203 and spiral blade 204 to rotate. The rotation of the spiral causes the catalyst material falling into funnel 201 to flow downwards, reducing accumulation. At the same time, rotating plate 302 driven by motor 202 also rotates. The catalyst material falling onto rotating plate 302 will fall into tank 1 from different directions through partition plate 303. This completes one addition of catalyst material. After the reaction in tank 1 has lasted for a period of time, catalyst material can be added to tank 1 again in the same way to maintain the normal supply of catalyst material in tank 1.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
