Description

Technical Field

[0001] This invention relates to the field of desulfurization and dust removal technology, and in particular to a desulfurization and dust removal device and system. Background Technology

[0002] Desulfurization and dust removal equipment is a key piece of equipment for industrial flue gas treatment. It mainly addresses the problem of excessive sulfur dioxide (SO2) and particulate matter (PM) emissions in flue gas from coal-fired boilers, steel smelting, cement kilns, and other similar environments, helping enterprises meet environmental emission standards (such as SO2 concentration ≤100mg / Nm³). 3 Particulate matter ≤30mg / Nm 3 Most existing desulfurization and dust removal devices remove sulfur dioxide and particulate matter from flue gas simultaneously through physical or chemical methods.

[0003] Desulfurization and dust removal equipment includes two processes: dust removal and desulfurization. Most existing desulfurization and dust removal equipment adopts electrostatic precipitators, bag filters, wet electrostatic precipitators, or cyclone filters, which separate particulate matter through electric field force, filter bag interception, or centrifugal force. For example, bag filters capture fine particulate matter of 0.1-10μm through filter bag fibers, with an efficiency of over 99.9%. During desulfurization, SO2 is converted into sulfate or elemental sulfur through chemical absorption processes such as limestone-gypsum method, ammonia method, and sodium alkali method, or physical methods such as activated carbon adsorption and electron beam irradiation. For example, the limestone-gypsum method sprays limestone slurry to make SO2 react with CaCO3 to generate CaSO3, which is further oxidized to gypsum (CaSO4·2H2O) for recycling.

[0004] Existing desulfurization and dust removal equipment mostly utilizes a desulfurization reaction slurry to react with the continuously introduced sulfur-containing waste gas after dust removal and cooling. The reaction between the desulfurizing agent slurry and the waste gas is generally divided into two categories: spray reaction and direct reaction. Direct reaction requires the pre-storage of a certain amount of desulfurizing agent slurry, which reacts directly with the introduced waste gas. Direct reaction has a faster reaction rate than spray reaction, and the subsequent treatment of by-products is also more convenient. However, because the concentration of the desulfurizing agent slurry changes continuously as it reacts with the waste gas, and the sulfur content of the introduced waste gas also changes continuously, if the sulfur content of the waste gas changes significantly, it is easy for the sulfur-containing waste gas and the desulfurizing agent slurry to react incompletely or for too much desulfurizing agent slurry to be introduced, resulting in unnecessary energy consumption. It is also difficult to make quick and flexible adjustments according to the continuous changes in the sulfur content of the waste gas, resulting in poor desulfurization treatment effect. Summary of the Invention

[0005] The purpose of this invention is to provide a desulfurization and dust removal device and system that can continuously and quantitatively deliver waste gas through certain components and detect a specified volume of waste gas so that a corresponding volume of desulfurizing agent slurry can be exported based on the detection results for reaction, making the reaction between waste gas and desulfurizing agent slurry more thorough and resulting in a better final desulfurization effect.

Detailed Implementation

[0031] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0032] In the description of this invention, it should be understood that "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] Please see Figures 1 to 11 This invention provides a desulfurization and dust removal device and system, comprising a working support 101, a gas guide box 102, and a reaction assembly. The reaction assembly includes a reaction cylinder 103, a rotary drive mechanism 104, a top support 105, a circulating gas guide component, a connecting component, and a material control component. The circulating gas guide component includes an inner plug rotating plate 201, a rotating motor 202, and a connecting support 203. The connecting component includes a three-way connector 301, an air inlet channel 302, an exhaust channel 303, and a synchronous control component. The material control component includes an upper support 401, an upper screw 402, an upper motor 403, and a discharge component. The synchronous control component includes a flow control valve 501, an external bevel gear 502, a synchronous bevel gear shaft 503, and a synchronous motor 504. The discharge component includes a material guide top frame 601, a pusher plate 602, a screw ejection mechanism 603, and a guide frame 604. This solution addresses the shortcomings of existing desulfurization and dust removal methods. When desulfurizing sulfur-containing waste gas after dust removal and cooling, most desulfurization equipment utilizes a desulfurization reaction slurry to react with the continuously introduced sulfur-containing waste gas. The reaction between the desulfurizing agent slurry and the waste gas is generally divided into two categories: spray reaction and direct reaction. Direct reaction requires the pre-storage of a certain amount of desulfurizing agent slurry, which reacts directly with the introduced waste gas. Direct reaction has a faster reaction rate than spray reaction, and the subsequent treatment of by-products is also more convenient. However, because the concentration of the desulfurizing agent slurry changes continuously as it reacts with the waste gas, and the sulfur content of the introduced waste gas also changes continuously, if the sulfur content of the waste gas changes significantly, it is easy for the sulfur-containing waste gas and the desulfurizing agent slurry to react incompletely or for too much desulfurizing agent slurry to be introduced, resulting in unnecessary energy consumption. It is also difficult to make quick and flexible adjustments according to the continuous changes in the sulfur content of the waste gas, leading to poor final desulfurization treatment results.

[0034] Furthermore, the gas guide box 102 is fixedly installed on the working support 101, the reaction cylinder 103 is rotatably installed on the working support 101, a partition is provided inside the reaction cylinder 103 to divide the reaction cylinder 103 into two independent areas, the rotary drive mechanism 104 is connected to the working support 101 and is used to drive the reaction cylinder 103 to rotate, the top sleeve 105 is fixedly installed on the working support 101 and is sleeved on the top of the reaction cylinder 103, the circulating gas guide component is connected to the gas guide box 102 and is used to complete the circulation of waste gas in and out, the connecting component is connected to the gas guide box 102 and is used to connect the gas guide box 102 to the top sleeve 105, and the material control component is connected to the reaction cylinder 103 and is used to regulate the desulfurizing agent slurry inside the reaction cylinder 103.

[0035] Specifically, the reaction area at the top of the reaction cylinder 103 is divided by a partition, so that the reaction area at the top of the reaction cylinder 103 is divided into two independent reaction areas, so that the waste gas per unit volume can be circulated through two different sections inside the reaction cylinder 103.

[0036] The top of the reaction cylinder 103 is provided with the top sleeve 105, which is provided with an air inlet slot and a desulfurizing agent slurry inlet. The upper and lower parts of the reaction area at the top of the reaction cylinder 103 are hollow structures. The outer ring of the top of the reaction cylinder 103 is provided with two sets of air inlet fitting holes and inlet fitting holes, which correspond to two independent reaction areas respectively.

[0037] The rotary drive mechanism 104 consists of an outer ring gear and a gear drive structure. The outer ring gear located at the bottom of the reaction cylinder 103, in conjunction with the corresponding gear drive structure, drives the reaction cylinder 103, enabling it to rotate on the working support 101. The rotation of the reaction cylinder 103 causes the two independent reaction zones at the top of the reaction cylinder 103 to alternate.

[0038] The side of the top frame 105 with the air inlet slot is the air inlet reaction station, and the side with the desulfurizing agent slurry inlet is the slurry inlet / outlet station. When one independent reaction area of ​​the top frame 105 introduces waste gas, the other independent reaction area of ​​the top frame 105 will complete the desulfurizing agent slurry outlet and the introduction of a new round of desulfurizing agent slurry. After one independent reaction area completes the introduction of a unit volume of waste gas, the desulfurizing agent slurry in the other independent reaction area is introduced. Then, the reaction cylinder 103 will rotate under the action of the rotary drive mechanism 104, so that the two independent areas alternate stations. Then, the desulfurizing agent slurry after reacting with the waste gas is exported, and the newly added desulfurizing agent slurry will react with the re-introduced unit volume of waste gas. This cycle continues, realizing the cyclic treatment of a unit volume of waste gas.

[0039] In actual operation, the exhaust gas is introduced through the gas guide box 102 in conjunction with the circulating gas guide component, with the volume of the gas guide box 102 itself as the unit. The introduced exhaust gas enters a corresponding independent area located in the reaction cylinder 103 through the connecting component and the top frame 105, and then reacts with the desulfurizing agent slurry in the corresponding independent area. Afterwards, the rotary drive mechanism 104 drives the reaction cylinder 103 to rotate, so that the desulfurizing agent slurry after the reaction can be discharged under the action of the material control component and the next round of desulfurizing agent slurry can be introduced. Thus, the reaction cylinder 103 is set up... The two independent reaction zones, in conjunction with the air guiding and material guiding structure of the top frame 105, complete the circulation treatment of a unit volume of waste gas. Moreover, the material control component can adjust the amount of desulfurizing agent slurry introduced according to the waste gas detection structure in the air guiding box 102, so as to ensure that the subsequent waste gas and desulfurizing agent slurry react fully and thoroughly. This enables the continuous quantitative delivery of waste gas through the provided components, and the detection of a specified volume of waste gas, so that the corresponding volume of desulfurizing agent slurry can be exported for reaction based on the detection results, making the reaction between waste gas and desulfurizing agent slurry more thorough and resulting in a better final desulfurization treatment effect.

[0040] Furthermore, the inner plug rotating plate 201 is rotatably installed inside the air guide box 102, and the air guide box 102 is divided into two independent areas, left and right, by the provided inner partition and the inner plug rotating plate 201; the output shaft of the rotating motor 202 is connected to the inner plug rotating plate 201, and the rotating motor 202 is fixedly installed on one side of the air guide box 102; two connecting brackets 203 are installed on one side of the air guide box 102, and the two connecting brackets 203 are respectively connected to the left and right areas of the air guide box 102.

[0041] In this embodiment, when in use, the air guide box 102 is provided with an inner partition, and the two connecting brackets 203 are installed inside the inner partition. The two connecting brackets 203 have opposite conduction directions. The inner plug rotating plate 201 is also rotatably installed inside the air guide box 102. The inner plug rotating plate 201 is driven by the rotating motor 202.

[0042] In actual operation, the rotating motor 202 drives the inner plug rotating plate 201 to rotate. The rotation of the inner plug rotating plate 201, in conjunction with the inner partition set inside the air guide box 102, allows the two independent left and right areas to continuously expand and compress respectively. The side that is continuously expanding will draw in exhaust gas, while the side that is continuously compressing will expel exhaust gas. In this way, by the continuous back and forth rotation of the inner plug rotating plate 201, a certain volume of exhaust gas can be drawn in and discharged, thereby achieving the guiding of a unit volume of exhaust gas.

[0043] Furthermore, the first interfaces of the two three-way connectors 301 are respectively connected to the two connecting brackets 203; the air intake channel 302 is connected to the second interfaces of the two three-way connectors 301; one side of the exhaust channel 303 is connected to the third interfaces of the two three-way connectors 301, and the other side of the exhaust channel 303 is connected to the top bracket 105; the synchronous control component is connected to the three-way connectors 301 and is used to synchronously control the two three-way connectors 301.

[0044] Furthermore, each of the three-way connectors 301 is equipped with a flow control valve 501; each of the flow control valves 501 is fixedly mounted with an external bevel gear 502; the synchronous bevel gear shaft 503 is rotatably mounted on one side of the air guide box 102, and the synchronous bevel gear shaft 503 is provided with two bevel gears with the same transmission direction, and the two external bevel gears 502 are respectively connected to the two bevel gears on the synchronous bevel gear shaft 503; the output shaft of the synchronous motor 504 is connected to the synchronous bevel gear shaft 503, and the synchronous motor 504 is fixedly mounted on one side of the air guide box 102.

[0045] In this embodiment, the connecting bracket 203 is fixed with the three-way connector 301 on each side. The two three-way connectors 301 are respectively connected to the air inlet channel 302 and the exhaust channel 303 on both sides. The exhaust channel 303 is connected to the air inlet slot of the top bracket 105. The air inlet channel 302 is connected to the exhaust gas inlet of the dust removal structure so as to facilitate the introduction of sulfur-containing exhaust gas through the air inlet channel 302.

[0046] The three-way connector 301 is equipped with the flow control valve 501. The flow control valve 501 has an "L"-shaped conduction structure. By rotating the flow control valve 501, one of the air intake channel 302 and the exhaust channel 303 can be connected to the corresponding connecting bracket 203.

[0047] Since the exhaust gas in the air guide box 102 is drawn in and expelled by the rotation of the inner plug rotating plate 201, the two connecting brackets 203 will continuously draw in and discharge gas due to the rotation direction of the inner plug rotating plate 201. Therefore, the flow control valve 501 is needed to switch the connection of the two connecting brackets 203 according to the rotation direction of the inner plug rotating plate 201, so that the air intake channel 302 and the exhaust channel 303 can continuously draw in and discharge exhaust gas.

[0048] The flow control valves 501 inside the two three-way connectors 301 have opposite conduction directions. When the flow control valve 501 in the upper three-way connector 301 guides the upper connecting bracket 203 to connect with the air intake channel 302, the flow control valve 501 in the lower three-way connector 301 will guide the lower connecting bracket 203 to connect with the exhaust channel 303, thereby realizing the continuous intake and exhaust of exhaust gas.

[0049] Both flow control valves 501 are fixed with external bevel gears 502 on their outer sides. The two external bevel gears 502 respectively cooperate with two bevel gears on the synchronous bevel gear shaft 503. The synchronous bevel gear shaft 503 is driven by the synchronous motor 504. When the synchronous motor 504 drives the synchronous bevel gear shaft 503 to rotate, the synchronous bevel gear shaft 503 will drive the two external bevel gears 502 and the two flow control valves 501 to rotate, so as to realize the synchronous drive of the two flow control valves 501.

[0050] Furthermore, the two upper support brackets 401 are slidably installed at the bottom of the reaction cylinder 103, and the two upper support brackets 401 respectively cooperate with two independent areas of the reaction cylinder 103; the two upper screw rods 402 are threadedly connected to the two upper support brackets 401 respectively; the output shafts of the two upper motors 403 are respectively connected to the two upper screw rods 402, and the two upper motors 403 are fixedly installed at the bottom of the reaction cylinder 103; the discharge component is connected to the top sleeve 105, and is used to discharge the desulfurizing agent slurry after reaction inside the reaction cylinder 103 in a timely manner.

[0051] Furthermore, the material guide top frame 601 is fixedly installed on the top of the sleeve top frame 105; the material pusher plate 602 is slidably installed on one side of the material guide top frame 601; the screw ejection mechanism 603 is connected to the material guide top frame 601 and is used to drive the material pusher plate 602; the guide frame 604 is fixedly installed on one side of the material guide top frame 601.

[0052] In this embodiment, the two upper support brackets 401 are respectively adapted to the two independent areas separated by the reaction cylinder 103. Each upper support bracket 401 is equipped with a set of upper screw 402 and an upper motor 403 for driving. The upper motor 403 drives the upper screw 402 to rotate, and the rotation of the upper screw 402 drives the upper support bracket 401.

[0053] The movement of the two upper support brackets 401 in the independent area at the top of the reaction cylinder 103 can adjust the reaction space in the independent areas on both sides of the reaction cylinder 103, so that the appropriate reaction space can be adjusted according to different doses of desulfurizing agent slurry, so that the introduced gas can react quickly with the added desulfurizing agent slurry. At the same time, the slurry in the corresponding area of ​​the reaction cylinder 103 can be pushed out by the movement of the upper support brackets 401.

[0054] The material guide top frame 601 is installed on the slurry inlet / outlet station of the top frame 105. The material guide top frame 601 is equipped with the material pusher plate 602 for cooperation. The material pusher plate 602 is driven by the screw push mechanism 603. The screw push mechanism 603 has the same composition and driving principle as the upper push screw 402 and the upper push motor 403. The guide frame 604 is installed on the side of the material guide top frame 601.

[0055] When discharging the slurry inside the reaction cylinder 103, the ejector bracket first pushes the slurry out from the top of the reaction cylinder 103, allowing the slurry to enter the guide bracket 601. Then, excess slurry will be discharged through the guide bracket 601 and the guide frame 604. At the same time, the pusher plate 602 provided on the guide bracket 601 will also push the slurry inside the guide bracket 601 horizontally under the action of the screw ejection mechanism 603, so that the slurry can be discharged through the guide frame 604. At the same time, the slurry at the top of the upper bracket 401 can also be scraped off and pushed out, reducing the impact of residual slurry on subsequent new slurry.

[0056] Preferably, the reaction assembly provided by the present invention further includes a mounting bracket 701, a transfer bracket 702, a flip motor 703, a monitoring component, and a purging component. The monitoring component includes a clamping monitoring instrument 801, a turn lever 802, a compression frame 803, and a compression spring 804. The purging component includes a top cover 901, a lead screw lateral movement mechanism 902, a double-pass frame 903, a one-way valve 904, and an air pump 905.

[0057] Furthermore, the mounting bracket 701 is fixedly installed on the top of the gas guide box 102; the transfer frame 702 is rotatably installed inside the mounting bracket 701; the output shaft of the flip motor 703 is connected to the transfer frame 702, and the flip motor 703 is fixedly installed on one side of the mounting bracket 701; the monitoring component is connected to the transfer frame 702 and is used to detect the sulfur content of the exhaust gas inside the gas guide box 102; the purging component is connected to the gas guide box 102 and is used to purge and clean the detection element.

[0058] Furthermore, the two card-mounted monitoring instruments 801 are respectively installed on both sides of the transfer frame 702; each card-mounted monitoring instrument 801 has a fixed rotating rod 802 on its surface; the compression frame 803 is slidably installed on the side of the transfer frame 702 near the card-mounted monitoring instrument 801, and the two compression frames 803 are respectively arranged in a one-to-one correspondence with the two card-mounted monitoring instruments 801 set on the transfer frame 702; the two sides of the compression spring 804 are respectively connected to the compression frame 803 and the transfer frame 702, and the two compression springs 804 are respectively arranged in a one-to-one correspondence with the two compression frames 803.

[0059] In this embodiment, the mounting bracket 701 is positioned above the air guide box 102. The mounting bracket 701 has corresponding openings on both its upper and lower sides. The mounting bracket 702 is rotatably mounted inside the mounting bracket 701. The mounting bracket 702 has mounting slots on its upper and lower sides for mounting the mounting monitoring instrument 801. Each mounting slot is also provided with the compression frame 803 and the compression spring 804.

[0060] The surface of the card-mounted monitoring instrument 801 is an inductive element. By directly contacting the exhaust gas with the inductive element, the sulfur content of the exhaust gas can be measured. This allows for adjustment of the volume of the subsequently introduced slurry based on the detection results. The bottom of the card-mounted monitoring instrument 801 is provided with a protruding card. The card slot in the transfer frame 702 also has a corresponding outer ring card slot. When the card-mounted monitoring instrument 801 is pressed into the bottom of the card slot in the transfer frame 702, the operator can use the rotating lever 802 on the surface of the card-mounted monitoring instrument 801 to rotate it, causing the card-mounted monitoring instrument 801 to lock into place. Within the mounting bracket 702, as the mounting monitoring instrument 801 is pressed into the mounting slot, it continuously compresses the compression bracket 803 and the compression spring 804. This causes the compression spring 804 and the compression bracket 803 to apply pressure to the mounting monitoring instrument 801 after it is locked in place, ensuring stable installation of the mounting monitoring instrument 801. Furthermore, the compression bracket 803 and the compression spring 804 also allow the mounting monitoring instrument 801, which has lost its mounting limit, to be ejected directly from the mounting slot when the user twists or removes it.

[0061] The card-mounted monitoring instrument 801 can be either wired or wireless. When using wireless monitoring, the card-mounted monitoring instrument 801 needs to have its own power supply. Although it is more convenient to remove, replace, and access the device, the power supply needs to be replaced and maintained regularly. When using wired monitoring, the wiring structure inside the transfer frame 702 needs to be designed so that the wiring does not affect the normal flipping of the transfer frame 702.

[0062] The transfer frame 702 is equipped with two card-mounted monitoring instruments 801. The transfer frame 702 is driven by the flip motor 703. The two card-mounted monitoring instruments 801 can perform alternating monitoring, which avoids the situation where the monitoring sensitivity of one card-mounted monitoring instrument 801 decreases due to prolonged contact with sulfur-containing waste gas. At the same time, when one card-mounted monitoring instrument 801 is repaired or replaced, the other card-mounted monitoring instrument 801 can still work normally.

[0063] Furthermore, the top cover 901 is slidably mounted on the top of the mounting bracket 701; the lead screw lateral movement mechanism 902 is connected to the top cover 901 and is used to drive the top cover 901; the double-pass bracket 903 is fixedly mounted on the top cover 901; the one-way valve 904 is connected to one side of the double-pass bracket 903 through a conduit, and the one-way valve 904 is mounted on the top of the air guide box 102; the air pump 905 is connected to the double-pass bracket 903 through a conduit, and the air pump 905 is fixedly mounted on the top of the air guide box 102.

[0064] In this embodiment, the top cover 901 is adapted to the top opening of the mounting bracket 701. The top cover 901 is driven by the lead screw lateral movement mechanism 902. The lead screw lateral movement mechanism 902 has the same structural principle as the lead screw ejection mechanism 603. The top opening of the mounting bracket 701 can be opened by sliding the top cover 901, thereby allowing the installation and removal of the clamping monitoring instrument 801 on the transfer frame 702.

[0065] The top cover 901 is also equipped with the double-pass frame 903. The double-pass frame 903 has two independent conduction areas. The two conduction areas are connected to the one-way valve 904 and the air pump 905 respectively through conduits. The air inlet of the one-way valve 904 is connected to the double-pass frame 903, the air outlet of the one-way valve 904 is connected to the air guide box 102, and the air outlet of the air pump 905 is connected to the double-pass frame 903.

[0066] When the mounting monitoring instrument 801 on the transfer frame 702 is rotated to the top, the air pump 905 can introduce gas into the top of the transfer frame 702 through the conduit and the double-pass frame 903. Then, the airflow is used to blow the residual exhaust gas impurities on the mounting monitoring instrument 801 at the top back into the air guide box 102 through the one-way valve 904, so as to complete the automatic blowing and cleaning of the mounting monitoring instrument 801. In this way, the periodic alternation of the two mounting monitoring instruments 801 and the cyclic cleaning can greatly improve the working life and detection accuracy of the mounting monitoring instrument 801.
