Description

Technical Field

[0001] This invention relates to the field of waste gas processing technology, and in particular to a waste gas desulfurization and denitrification treatment device. Background Technology

[0002] Waste gas desulfurization and denitrification technology is a core process for controlling sulfur dioxide and nitrogen oxide emissions in modern industrial environmental protection. It is widely used in high-energy-consuming industries such as thermal power generation, steel smelting, chemical building materials, etc. In the standard desulfurization and denitrification process, the original high-temperature flue gas emitted from industrial furnaces must undergo a strict pretreatment process before entering the desulfurization tower or denitrification reactor. This is because the original industrial waste gas not only contains harmful gases, but also carries a large amount of high-temperature solid suspended matter, unburned carbon particles, condensed sludge, and hard slag.

[0003] In existing technologies, pretreatment of flue gas desulfurization and denitrification front-end often adopts fixed grids or scraper-equipped cleaning devices, which are installed in the main flue. They use fixed apertures to directly block large particles of waste residue in high-temperature flue gas, and the scrapers are driven by independent motors to clean back and forth. However, since the existing grid bars are mostly flat and lack the ability to squeeze and break up arches, when faced with sticky or hard scale, the waste residue is very easy to get stuck in the gaps and form bridging blockages. This causes the system wind resistance to rise sharply and seriously affects the continuous operation of downstream equipment. Secondly, during automatic cleaning and slag discharge, the cleaning and bottom conveying mechanisms usually rely on multiple independent power systems. The up and down movements are very easy to disconnect and form secondary accumulation blockages. Moreover, the fixed interception gap cannot be flexibly adjusted according to the actual particle size of the waste residue, resulting in extremely poor system adaptability, redundant structure, and easy mechanical jamming and paralysis.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0005] The purpose of this invention is to achieve in-situ compression and crushing of stuck solid waste by using a movable grid plate that moves linearly back and forth within a limiting groove, and by utilizing a structural design in which extrusion grid bars and fixed grid bars are arranged alternately and all have a rhomboid cross-section. This allows the extrusion protrusions of adjacent grid bars to approach each other and form a V-shaped interlocking gap. At the same time, the inclined rhomboid guide surface guides the crushed waste residue to flow down by gravity. This overcomes the shortcomings of existing grid bars, which are mostly flat cross-sections and lack the ability to compress and break up arches. When faced with sticky or hard scale, the waste residue is easily stuck in the gaps, forming a "bridging" blockage, which causes the system's wind resistance to rise sharply and seriously affects the continuous operation of downstream equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a waste gas desulfurization and denitrification treatment device, comprising an equipment shell and a fixed grid plate, wherein the fixed grid plate is fixedly installed on the inner wall of the equipment shell, and fixed grid strips are fixedly installed on the inner wall of the fixed grid plate; a sealing cover is provided on the top surface of the equipment shell; a limit sliding groove is provided on the inner wall of the equipment shell; an adjusting protective plate is fixedly installed on one side surface of the equipment shell; a collection groove is provided on the inner wall of the equipment shell; a debris discharge port is provided on the bottom surface of the equipment shell; a movable component is installed on the inner wall of the equipment shell; and a driving mechanism is installed on one side surface of the equipment shell.

[0007] The movable component includes a movable grid plate, a slider is installed on the outer surface of the movable grid plate, extruded grid strips are installed on the inner wall of the movable grid plate, an adjusting plate is fixedly installed on the outer surface of the movable grid plate, a slider is installed on one side surface of the movable grid plate, an adjusting hole is opened on the surface of the adjusting plate, and a linear reciprocating groove is provided on one side surface of the equipment housing.

[0008] Furthermore, there are several fixed grid strips, which are distributed in a linear array at equal intervals on the inner wall of the fixed grid plate. There are four limiting slide grooves, which are distributed in pairs on one side and the other side of the inner wall of the equipment housing. There are two adjusting protective plates, which are distributed on one side and the other side of the equipment housing.

[0009] Furthermore, the extruded grid strips are a number of linearly arrayed and equidistantly distributed on the inner wall of the movable grid plate. There are two adjusting plates, which are respectively distributed on one side and the other side surface of the movable grid plate. There are four sliders, which are distributed in pairs on one side and the other side surface of the movable grid plate. Each slider corresponds to a limiting groove, and the slider is slidably connected to the inner wall of the limiting groove.

[0010] Furthermore, there are several adjustment holes, which are arranged in a linear array on one side surface of the two adjustment plates. There are two linear reciprocating grooves, which are respectively distributed on one side and the other side surface of the equipment housing. The outer surface of the adjustment plate slides in contact with the inner wall of the linear reciprocating groove. The cross-sections of the fixed grid strips and the extruded grid strips are both rhomboid in shape, and the fixed grid strips and the extruded grid strips are arranged in an alternating manner to form a V-shaped interlocking gap between adjacent fixed grid strips and extruded grid strips.

[0011] Furthermore, the drive mechanism includes a transmission assembly and a discharge assembly. The transmission assembly includes a drive motor, which is fixedly mounted on one side surface of the equipment housing. A drive shaft is rotatably mounted on the inner wall of the collection tank. A spiral conveying blade is mounted on the outer surface of the drive shaft. Eccentric wheels are fixedly mounted at both ends of the drive shaft. A push-pull rod is mounted on the outer surface of the eccentric wheel. A reciprocating rod is rotatably connected to one end of the push-pull rod. An adjusting bolt is threadedly rotatably connected to one side surface of the reciprocating rod.

[0012] Furthermore, the output end of the drive motor is fixedly connected to one end of the transmission shaft. One end of the transmission shaft extends from the outer surface of the equipment housing to its inner wall. The eccentric wheels are two equidistantly distributed at one end and the other end of the transmission shaft. Each eccentric wheel has a push-pull rod correspondingly distributed on its outer surface, and each push-pull rod has a reciprocating rod correspondingly distributed at its end.

[0013] Furthermore, each of the reciprocating rods has an adjusting bolt distributed on one side surface. The adjusting bolt is rotatably connected to the inner wall of the adjusting hole. The two reciprocating rods correspond one-to-one with the two adjusting plates. The outer surface of the reciprocating rod is in sliding contact with the inner wall of the linear reciprocating groove.

[0014] Furthermore, the discharge assembly includes a bracket, which is fixedly installed on the bottom surface of the equipment housing. The top surface of the sealing cover is provided with a discharge inlet, and the bottom surface of the equipment housing is provided with a gas discharge outlet.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0016] 1. This waste gas desulfurization and denitrification treatment device uses a movable grid plate to move linearly back and forth in a limiting slide groove. It utilizes the structural design of extrusion grid bars and fixed grid bars arranged in an alternating manner, all with a rhomboid cross section. This allows the extrusion protrusions of adjacent grid bars to approach each other and form a V-shaped interlocking gap, achieving in-situ extrusion and pulverization of stuck solid waste. At the same time, the inclined rhomboid guide surface guides the pulverized waste residue to flow down by gravity. This compensates for the shortcomings of existing grid bars, which are mostly flat cross sections and lack the ability to extrude and break up arches. When faced with sticky or hard scale, the waste residue is easily stuck in the gap, forming a bridging blockage, which causes the system wind resistance to rise sharply and seriously affects the continuous operation of downstream equipment.

[0017] 2. The waste gas desulfurization and denitrification treatment device uses a drive motor to rotate the transmission shaft and the spiral conveying blades on its surface. The eccentric wheels at both ends of the transmission shaft synchronously pull the push-pull rod and the reciprocating rod, realizing a single-power mechanical hard linkage between the squeezing and cleaning of the upper grid and the spiral conveying of the bottom waste residue. Combined with the adjustment bolts on the reciprocating rod and the different adjustment holes on the surface of the adjustment plate, it achieves precise fine-tuning of the initial interception gap of the grid. This makes up for the shortcomings of the existing technology, which relies on multiple independent power systems for automatic cleaning and bottom slag discharge. This leads to the easy disconnection of the upper and lower movements, resulting in secondary accumulation and blockage. Moreover, the fixed interception gap cannot be flexibly adjusted according to the changing particle size of the waste residue in the actual working conditions. As a result, the entire pretreatment system has extremely poor adaptability to working conditions, redundant structure, and is prone to mechanical jamming and paralysis. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not 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 invention.

[0030] like Figures 1-9 As shown, a waste gas desulfurization and denitrification treatment device includes an outer shell 1, a fixed grid plate 101, movable components, and a drive mechanism.

[0031] Specifically, a fixed grid plate 101 is fixedly installed on the inner wall of the equipment housing 1. The inner wall of the fixed grid plate 101 is arranged in a linear array with equal spacing and a number of fixed grid strips 102 are fixedly installed. A sealing cover 103 is provided on the top surface of the equipment housing 1, and a debris discharge port 107 is opened on its bottom surface. A collection trough 106 is provided at the bottom of the inner wall of the housing.

[0032] In addition, in terms of structural guidance and protection, the inner walls of the equipment housing 1 are provided with limit sliding grooves 104 on both sides, a total of four, and two are symmetrically distributed on both sides of the inner walls. At the same time, two adjustable protective plates 105 are fixedly installed on both sides of the outer surface of the equipment housing 1. The movable components installed inside the equipment housing 1 have a drive mechanism installed on one side of the outer surface.

[0033] In this embodiment of the invention, when the eccentric wheel 303 rotates, the eccentric wheel 303 will directly pull the push-pull rod 304, converting the rotational force of the transmission shaft 301 into an oblique pulling and pushing force. After the reciprocating rod 305 is pulled, its outer surface moves downward along the straight reciprocating groove 205 set on one side surface of the equipment housing 1, and slides downward synchronously with the adjusting plate 203 and the movable grid plate 2 until the squeeze grid strip 202 is pressed tightly on the intercepted solid waste residue.

[0034] Reference Figures 1-9 Specifically, the movable component mainly includes a movable grating plate 2. On the inner wall of the movable grating plate 2, several extruded grating strips 202 are installed in a linear array and equidistantly distributed. It is worth noting that both the fixed grating strips 102 and the extruded grating strips 202 have a rhomboid cross-section, and they are arranged in an alternating pattern, thus forming a V-shaped interlocking gap between adjacent fixed grating strips 102 and extruded grating strips 202.

[0035] In terms of motion guidance, four sliders 201 are installed on the outer surfaces of both sides of the movable grid plate 2, and two sliders 201 are symmetrically distributed on both sides; the sliders 201 correspond one-to-one with the limiting grooves 104 on the inner wall of the equipment housing 1, and maintain a sliding connection with its inner wall.

[0036] In terms of adjustment and linkage, two adjustment plates 203 are fixedly installed on both sides of the movable grid plate 2, and each adjustment plate 203 has several adjustment holes 204 arranged in a linear array on one side surface. Correspondingly, two linear reciprocating grooves 205 are opened on both sides of the equipment housing 1, and the outer surface of the adjustment plate 203 extends into the linear reciprocating groove 205 and slides in contact with its inner wall.

[0037] In this embodiment of the invention, during the downward movement and opening compression process, the four sliders 201 installed on the outer surface and one side surface of the movable grid plate 2 slide precisely within the limiting groove 104 opened on the inner wall of the equipment housing 1, ensuring the absolute accuracy of the reciprocating movement direction of the movable grid plate 2 and the synchronicity of both sides. When the extruded grid strip 202 is pressed tightly and the waste residue is instantly crushed by the huge wedge-shaped lateral force, the lower half of the inclined surface of the diamond grid strip plays an extremely stable guiding and sliding role. The crushed residue loses its adhesion and falls into the collection tank 106 along the inclined surface under the influence of gravity. At the same time, since the drive shaft 301 is continuously rotating, the spiral conveying blades 302 installed on its outer surface are synchronously pushing and rotating, continuously pushing the crushed residue that has fallen into the tank towards the position where the crushed material discharge outlet 107 is opened on the bottom surface of the equipment housing 1 for discharge. This single-power linkage method with direct bottom shaft connection ensures that the ash removal mechanism always works synchronously with the slag discharge mechanism and will not cause deviations in ash accumulation and blockage due to power delay.

[0038] Reference Figures 1-9Specifically, the drive mechanism includes a transmission assembly and a discharge assembly. The power source for the transmission assembly is a drive motor 3, which is fixedly mounted on one outer surface of the equipment housing 1, with its output end fixedly connected to one end of a drive shaft 301. The drive shaft 301 extends from the outside of the equipment housing 1 into the internal collection trough 106 and remains rotatably mounted. A spiral conveyor blade 302 for slag discharge is mounted on the outer surface of the drive shaft 301.

[0039] In order to convert rotational power into linear reciprocating power and ensure synchronization on both sides, two eccentric wheels 303 are equidistantly distributed and fixedly installed at both ends of the drive shaft 301; a push-pull rod 304 is rotatably connected to the outer surface of each eccentric wheel 303, and a reciprocating rod 305 is rotatably connected to the end of each push-pull rod 304.

[0040] In terms of motion guidance and spacing adjustment, the two reciprocating rods 305 correspond one-to-one with the two adjusting plates 203 on both sides of the movable component. The outer surface of the reciprocating rod 305 maintains sliding contact with the inner wall of the linear reciprocating groove 205 on the equipment housing 1 to obtain precise linear displacement guidance; at the same time, each reciprocating rod 305 has an adjusting bolt 306 on one side surface, which passes through the reciprocating rod 305 and is threadedly rotated to the inner wall of the adjusting hole 204 on the adjusting plate 203, thereby realizing stepless adjustment of the linkage spacing between the transmission mechanism and the movable grid plate.

[0041] In this embodiment of the invention, after the gap position is changed and the protective plate is reinstalled, the drive motor 3 is restarted and rotated under control until the transmission shaft 301 drives the eccentric mechanism to operate smoothly again. The spiral conveying blades 302 and the movable grid plate 2 continue to perform subsequent synchronous slag discharge and crushing. After the desulfurization pretreatment task is completed, the drive motor 3 stops rotating, the eccentric wheel 303 rotates back to its highest point, the push-pull rod 304 withdraws its downward pulling force, and the movable component and the crushing grid bar 202 retract obliquely upward. Finally, by cutting off the external airflow, the entire treatment device is safely shut down from the harsh high-temperature exhaust gas environment. Through the above complete mechanical linkage process, the present invention successfully achieves efficient integrated treatment of desulfurization and denitrification exhaust gas filtration, in-situ high-pressure arch breaking and crushing, and automatic slag removal.

[0042] The discharge assembly includes a bracket 4, which is fixedly installed on the bottom surface of the equipment housing 1. The top surface of the sealing cover 103 is provided with a discharge inlet 401, and the bottom surface of the equipment housing 1 is provided with a gas discharge outlet 402.

[0043] Specific usage process: Before the waste gas desulfurization and denitrification treatment device of the present invention is put into operation, the entire device must be firmly fixed on the support platform of the external flue pipe by the bracket 4 fixedly installed on the bottom surface of the equipment shell 1, and the waste gas inlet pipe to be treated is firmly connected to the discharge port 401 set on the top surface of the sealing cover 103, while the gas discharge port 402 is sealed and connected to the downstream desulfurization tower equipment.

[0044] In the initial state, the drive shaft 301 is in the starting position, and the adjusting plate 203 installed on the outer surface of the movable grid plate 2 is also in the initial posture. Since the adjusting hole 204 on the surface of the adjusting plate 203 is fixedly connected to the adjusting bolt 306 on one side of the reciprocating rod 305 by thread, the push-pull rod 304 will not generate a downward traction force in the initial phase, so that the movable grid plate 2 and the extrusion grid strip 202 installed on its inner wall are in a retracted state at an angle upward. At this time, there is a sufficiently wide V-shaped safety gap between the extrusion grid strip 202 and the fixed grid strip 102 fixedly installed on the fixed grid plate 101 on the inner wall of the equipment housing 1, to ensure that the exhaust gas can pass through smoothly in the initial stage of ventilation. After the preparation is completed, the exhaust system is started. The exhaust gas carrying solid impurities flows into the equipment shell 1 through the discharge inlet 401 for desulfurization and denitrification pretreatment. In this stage, since the grid bars are all diamond-shaped and arranged in an inclined and staggered manner, the exhaust gas can pass through the gaps smoothly with extremely low wind resistance and be discharged from the gas outlet 402. Large pieces of waste residue are intercepted on the windward side. At this time, the drive motor 3 remains stationary and the grid bars will not be squeezed or rubbed relative to the waste residue.

[0045] When the device reaches the set time for dust removal, the drive motor 3, which is fixedly installed on one side of the bracket 4, starts and drives the transmission shaft 301 to rotate continuously in the inner wall of the collection tank 106. As the transmission shaft 301 rotates, the eccentric wheels 303, which are fixedly installed at both ends of the transmission shaft 301, also rotate synchronously. Since there is an eccentric linkage between the outer surface of the eccentric wheel 303 and the push-pull rod 304, when the eccentric wheel 303 rotates, it will directly pull the push-pull rod 304, converting the rotational force of the transmission shaft 301 into an oblique pulling force. After the reciprocating rod 305 is pulled, its outer surface moves downward along the straight reciprocating groove 205 set on one side of the equipment housing 1, and slides downward synchronously with the adjusting plate 203 and the movable grid plate 2 until the squeeze grid bar 202 is pressed against the intercepted solid waste.

[0046] During the downward movement and opening compression process, the four sliders 201 installed on the outer surface and one side surface of the movable grid plate 2 slide precisely within the limiting groove 104 opened on the inner wall of the equipment shell 1, ensuring the absolute accuracy of the reciprocating movement direction of the movable grid plate 2 and the synchronicity of both sides. When the extruded grid strip 202 is pressed tightly and the waste residue is crushed instantly by the huge wedge-shaped lateral force, the lower half of the inclined surface of the diamond grid strip plays an extremely stable guiding and sliding role. The crushed residue loses its adhesion and falls into the collection tank 106 along the inclined surface under the influence of gravity. At the same time, since the drive shaft 301 is continuously rotating, the spiral conveying blades 302 installed on its outer surface are synchronously pushing and rotating, continuously pushing the crushed residue that has fallen into the tank towards the position where the crushed material discharge outlet 107 is opened on the bottom surface of the equipment shell 1 for discharge. This single-power linkage method with direct bottom shaft connection ensures that the ash cleaning mechanism always works synchronously with the slag discharge mechanism and will not cause deviations in ash accumulation and blockage due to power delay.

[0047] When the crushing reaches the predetermined requirements and slag discharge continues, if the particle size and gap of the device for intercepting waste slag need to be changed due to changes in the front-end combustion conditions, the drive motor 3 will first stop rotating. The system operator will remove the adjustment protection plate 105 fixedly installed on one side of the equipment shell 1, loosen the adjustment bolt 306 and remove it from the current adjustment hole 204, and then slightly retract or extend the movable grid plate 2 by finely adjusting its position. Subsequently, the adjustment bolt 306 will be re-locked in another adjustment hole 204 on the adjustment plate 203 corresponding to different gap positions, thereby changing the initial engagement reference position.

[0048] After the gap position is changed and the protective plate is reinstalled, the drive motor 3 starts rotating again under control until the transmission shaft 301 drives the eccentric mechanism to run smoothly again. The spiral conveyor blades 302 and the movable grid plate 2 continue to perform subsequent synchronous slag discharge and crushing. After the desulfurization pretreatment task is completed, the drive motor 3 stops rotating, the eccentric wheel 303 rotates back to its highest point, the push-pull rod 304 withdraws the downward pulling force, and the movable component and the crushing grid bar 202 retract obliquely upward. Finally, by cutting off the external airflow, the entire treatment device is safely shut down from the harsh high-temperature exhaust gas environment. Through the above complete mechanical linkage process, the present invention successfully realizes efficient integrated treatment of desulfurization and denitrification exhaust gas filtration, in-situ high-pressure arch breaking and crushing, and automatic slag removal.

[0049] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
