Description

Technical Field

[0001] The present invention relates to the technical field of flue gas purification, and particularly to a flue gas particulate matter purification device for air pollution. Background Art

[0002] Bag dust collectors (also known as cartridge dust collectors) are suitable for collecting fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, and the fibrous fabric is used to filter the dust-containing gas. When the dust-containing gas enters the bag dust collector, dust with large particles and high specific gravity settles down due to the action of gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, and the gas is purified. The flue gas treatment equipment is to effectively treat the toxic and harmful substances contained in the flue gas to below the specified concentration, and corrosion or blockage of the equipment should be avoided. When filtering the floating dust particles in the flue gas, it is necessary to remove and clean the filter equipment inside the purification equipment, which is rather cumbersome. Chinese Patent Publication No.: CN113350909B discloses "A Bag Dust Collector". In this patent, by setting a striking device, when there is a lot of dust adsorbed on the filter bag or the dust caking occurs, the driving member is started. The driving member drives the rotating shaft to rotate, the rotating shaft drives the one-way ratchet to rotate, the one-way ratchet drives the striking rod to move, and the return spring makes the striking rod return to its original position, so that the striking rod intermittently strikes the inner side wall of the filter bag, causing the filter bag to deform, so that the dust or dust caking is separated from the filter bag, and the dust and dust caking settle to the ash hopper, improving the dust removal effect of the filter bag.

[0003] In the existing flue gas particulate matter purification device for air pollution, due to the defect of the structural design, there are problems that the air inlet flow rate of the filter cartridge closer to the air inlet pipe is relatively large, the filter cartridge is subjected to a relatively severe impact and is prone to breakage, and the impurities in the flue gas are easily agglomerated and deposited at the bottom of the purification equipment and are difficult to discharge.

[0008] Among them, the air distribution mechanism includes an air distribution pipe. The position of the air distribution pipe surface close to the end face is fixedly installed on the inner side of the purification box. A net plate is fixedly connected to the inner side of the air distribution pipe. A first screw slide is fixedly connected to the top of the air distribution pipe. The output end of the first screw slide is fixedly connected with a dust scraping component.

The magnetic ring is placed at the bottom of the inner side of the filter cartridge. The flue gas is transported to the inside of the purification box through the air inlet pipe. The air outlet pipe is externally connected to a fan so that the flue gas passes through the filter cartridge for filtration. The purified gas is led out through the air outlet pipe. The flue gas is transported to the inside of the air distribution pipe. The air distribution pipe is arranged directly below a plurality of filter cartridges. The magnetic attraction between the electromagnet and the magnetic ring makes the filter cartridge in a straightened state, avoiding the filter cartridge being blown up and damaged when the wind pressure is too high. The flue gas is shunted by the air distribution pipe.

[0010] Preferably, an electromagnet is fixedly connected to the top of the support frame. The number of the net plates is two. Holes are opened at positions on the air distribution pipe surface close to the net plates. The number of the wind guiding components is two.

The first screw slide drives the right-angle strip to reciprocate on the surface of the air distribution pipe. The inner sliding ring is arranged on the inner side of the air distribution pipe. When the flue gas impacts on the surface of the inner sliding ring, the flue gas is blocked by the inner sliding ring. Part of the flue gas is guided to the net plate through the openings on the surface of the air distribution pipe. The number of the net plates is set to two.

When the electromagnet is energized, it attracts the magnetic ring, so that the filter cartridge is straightened and not easily blown by the air pressure. At the same time, when the hydraulic cylinder drives the support frame to move up and down, the support frame will make the filter cartridge shake up and down through magnetic attraction, and cooperate with the air flusher to spray high-pressure gas into the inner side surface of the filter cartridge.

Soot and easily sticky particles such as metal particles fall to the upper position of the opening plate. The second lead screw slide drives the inclined plate to move horizontally back and forth, so that the extension roller moves back and forth on the top of the opening plate. While the extension roller is moving, the second motor drives it to rotate, and the spiral blade is driven to rotate at the upper position of the opening plate.

The extension pipe supports and fixes the right-angle bar and the arc plate, and the right-angle bar and the arc plate are used to scrape the outer side of the air distribution pipe. The inner sliding ring scrapes the inner side of the air distribution pipe driven by the first lead screw slide. Under the blowing of the flue gas, the dust particles are not easily adhered to the surface of the air distribution pipe, and the dust and sticky particles fall to the upper position of the opening plate.

[0020] The present invention provides a flue gas particulate matter purification device for air pollution. It has the following beneficial effects:

[0021] 1. For this flue gas particulate matter purification device for air pollution, under the obstruction of the ash scraping component, part of the flue gas flows through the holes of the air distribution pipe to the mesh plate, and the remaining part of the flue gas flows through the air distribution pipe to the air guiding component. The mesh plate evenly disperses the flue gas, and the air guiding component throws the flue gas towards the filter cartridge away from the air inlet pipe. The ash scraping component scrapes off the dust deposited on the inner and outer sides of the air distribution pipe. During this process, the flue gas is evenly guided to the filter cartridge, solving the problem that the air inlet flow rate of the filter cartridge closer to the air inlet pipe is relatively large, and the filter cartridge is easily damaged due to the relatively strong impact.

[0022] 2. For this flue gas particulate matter purification device for air pollution, driven by the first lead screw slide, the position where the flue gas is discharged from the air distribution pipe is different. The remaining part of the flue gas passes through the inner sliding ring and flows along the air distribution pipe. Subsequently, this part of the flue gas impacts on the surface of the guide vane. The structure of the guide vane is spiral, and the side of the guide vane surface close to the first motor expands outward. When the first motor drives a plurality of guide vanes to rotate, the flue gas is thrown out so that this part of the flue gas can be evenly dispersed into the purification box, enabling the flue gas to evenly pass through a plurality of filter cartridges, and the purification efficiency of the filter cartridges is higher.

[0023] 3. For this flue gas particulate matter purification device for air pollution, the second lead screw slide drives the stirring component to move above the opening plate. The stirring component mixes the dust and sticky particles and then drops them to the upper position of the pushing component. When the electric cylinder controls the pushing component to move upward and then push downward, the dust is pushed out of the ash discharge cylinder. The guiding of the inclined frame enables the pushing component to obstruct the dust particles when resetting, avoiding the dust particles from sticking to the inner wall of the ash discharge cylinder and being difficult to discharge, and solving the problem that the impurities in the flue gas are easily stuck into lumps and deposited at the bottom of the purification equipment and are difficult to discharge.

[0024] 4. In the flue gas particulate matter purification device for air pollution, there is a certain distance between the inner side surface of the spiral sheet and the extension roller. The soot can pass through the inner side surface of the spiral sheet and is not easily adhered to the surface of the spiral sheet. At this time, the ash pushing plate is located below the surface of the inclined frame. The ash pushing plate and the L-shaped strip obstruct the soot particles. A soot layer is formed at the position between the perforated plate and the ash pushing plate. The soot layer ensures that the wind pressure of the flue gas passing through the filter cartridge is large enough. The wrapping of the particles by the soot can effectively prevent the particles from sticking to the inner side surface of the ash discharge cylinder and being unable to be discharged.

[0025] 5. In the flue gas particulate matter purification device for air pollution, when the ash pushing plate is driven by the electric cylinder to move upward, one end of the connecting strip slides out of the ash pushing plate. At the same time, the other end of the connecting strip slides on the inner side surface of the L-shaped strip. The ash pushing plate is lifted, and the soot particles are discharged from the ash discharge cylinder through the position between the ash pushing plate and the L-shaped strip. When the ash pushing plate is driven to move downward, the soot particles are intermittently discharged, which can prevent excessive accumulation and caking of the soot and blockage, and also prevent the flue gas from overflowing from the bottom of the ash discharge cylinder.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] The first embodiment: As Figures 1-3 shown, the present invention provides a technical solution: A flue gas particulate matter purification device for air pollution, including a frame body 1, a purification box 2 is fixedly connected to the top of the frame body 1, an air impactor 3 is fixedly connected to the top of the purification box 2, a filter cartridge 6 is fixedly connected to the upper position of the inner side surface of the purification box 2, an air inlet pipe 4 is fixedly connected to the lower position of the surface of the purification box 2, an air outlet pipe 5 is fixedly connected to the upper position of the surface of the purification box 2, an ash discharge cylinder 7 is fixedly connected to the bottom of the purification box 2, and further includes:

[0038] An air distribution mechanism 8, the surface of the air distribution mechanism 8 is fixedly installed at the position of the inner side surface of the purification box 2 close to the air inlet pipe 4, the air distribution mechanism 8 is arranged directly below the filter cartridge 6, and the air distribution mechanism 8 is used for guiding the gas to be purified and downward limiting the bottom of the filter cartridge 6;

[0039] An ash discharge mechanism 9, the surface of the ash discharge mechanism 9 is fixedly installed on the inner side surface of the ash discharge cylinder 7, and the ash discharge mechanism 9 is used for stirring and mixing dry dust and sticky particles and intermittently pushing and discharging the mixture;

[0040] Among them, the air distribution mechanism 8 includes an air distribution pipe 81. The position of the air distribution pipe 81 close to the end face on the surface is fixedly installed on the inner side surface of the purification box 2. A net plate 82 is fixedly connected to the inner side surface of the air distribution pipe 81. A first lead screw slide 86 is fixedly connected to the top of the air distribution pipe 81. The output end of the first lead screw slide 86 is fixedly connected with a dust scraping component 87. One end of the air distribution pipe 81 far from the air inlet pipe 4 is fixedly connected with a wind guiding component 88;

[0041] The air distribution mechanism 8 further includes a hydraulic cylinder 83 and a magnetic ring 85. The bottom of the hydraulic cylinder 83 is fixedly installed on the surface of the air distribution pipe 81. The output end of the hydraulic cylinder 83 is fixedly connected with a support frame 89. The magnetic ring 85 is placed at the bottom of the inner side surface of the filter cartridge 6;

[0042] The top of the support frame 89 is fixedly connected with an electromagnet 84. The number of the net plates 82 is two. Holes are formed in the position of the air distribution pipe 81 close to the net plate 82. The number of the wind guiding components 88 is two.

[0043] During use, the flue gas is conveyed into the interior of the purification box 2 through the air inlet pipe 4. The air outlet pipe 5 is externally connected to a fan so that the flue gas passes through the filter cartridge 6 and is filtered. The purified gas is led out through the air outlet pipe 5. The flue gas is conveyed into the interior of the air distribution pipe 81. The air distribution pipe 81 is arranged directly below a plurality of filter cartridges 6. The magnetic attraction between the electromagnet 84 and the magnetic ring 85 makes the filter cartridge 6 in a straightened state, avoiding the filter cartridge 6 being damaged due to being blown upward when the wind pressure is too high. The flue gas is distributed by the air distribution pipe 81. Blocked by the dust scraping component 87, part of the flue gas flows through the holes of the air distribution pipe 81 to the net plate 82, and the remaining part of the flue gas flows through the air distribution pipe 81 to the wind guiding component 88. The net plate 82 evenly disperses the flue gas. The wind guiding component 88 throws the flue gas towards the filter cartridge 6 far from the air inlet pipe 4. The dust scraping component 87 scrapes off the dust deposited on the inner side surface and the outer side surface of the air distribution pipe 81. During this process, the flue gas is evenly guided to the filter cartridge 6, solving the problem that the air inlet flow rate of the filter cartridge closer to the air inlet pipe is relatively large, and the filter cartridge is easily damaged due to the relatively strong impact.

[0044] The second embodiment: As Figures 3-6 shown, the dust scraping component 87 includes an extension pipe 871. The top end of the extension pipe 871 is fixedly installed at the output end of the first lead screw slide 86. The bottom end of the extension pipe 871 is fixedly installed with an arc-shaped plate 872. The dust scraping component 87 further includes a right-angle strip 873. The top end of the right-angle strip 873 is fixedly installed above the surface of the extension pipe 871. The bottom of the output end of the first lead screw slide 86 is fixedly connected with an inner sliding ring 874. The wind guiding component 88 includes a fixed disk 881. The surface of the fixed disk 881 is fixedly installed at the position of the air distribution pipe 81 close to the end face. The middle position of the surface of the fixed disk 881 is fixedly connected with a first motor 882. The output end of the first motor 882 is fixedly connected with a guide vane 883.

[0045] During use, the air distribution pipe 81 diverts the flue gas. The first lead screw slide 86 drives the right-angle strip 873 to reciprocate on the surface of the air distribution pipe 81. The inner sliding ring 874 is arranged on the inner side surface of the air distribution pipe 81. When the flue gas impacts on the surface of the inner sliding ring 874, the flue gas is blocked by the inner sliding ring 874, and part of the flue gas is guided to the mesh plate 82 through the openings on the surface of the air distribution pipe 81. The number of mesh plates 82 is set to two. After the flue gas passes through the mesh plates 82, it is attracted upward and passes through the filter cartridge 6 to achieve filtration. Driven by the first lead screw slide 86, the positions where the flue gas is discharged from the air distribution pipe 81 are different. The remaining part of the flue gas passes through the inner sliding ring 874 and flows along the air distribution pipe 81. Subsequently, this part of the flue gas impacts on the surface of the guide vane 883. The structure of the guide vane 883 is spiral, and the side of the guide vane 883 surface close to the first motor 882 expands outward. When the first motor 882 drives a plurality of guide vanes 883 to rotate, the flue gas is thrown out so that this part of the flue gas can be evenly dispersed into the purification box 2, enabling the flue gas to uniformly pass through a plurality of filter cartridges 6, and the purification efficiency of the filter cartridges 6 is higher.

[0046] Third embodiment: As Figure 3 、 Figure 7 shown, the position of the air distribution pipe 81 surface close to the end face is fixedly installed on the inner side surface of the purification box 2. The inner side surface of the air distribution pipe 81 is fixedly connected with a mesh plate 82. The top of the air distribution pipe 81 is fixedly connected with a first lead screw slide 86. The output end of the first lead screw slide 86 is fixedly connected with a dust scraping assembly 87. One end of the air distribution pipe 81 far from the air inlet pipe 4 is fixedly connected with a wind guiding assembly 88;

[0047] The air distribution mechanism 8 further includes a hydraulic cylinder 83 and a magnetic ring 85. The bottom of the hydraulic cylinder 83 is fixedly installed on the surface of the air distribution pipe 81. The output end of the hydraulic cylinder 83 is fixedly connected with a support frame 89. The magnetic ring 85 is placed at the bottom of the inner side surface of the filter cartridge 6;

[0048] The top of the support frame 89 is fixedly connected with an electromagnet 84. The number of mesh plates 82 is two. Openings are provided at the positions of the air distribution pipe 81 surface close to the mesh plates 82. The number of wind guiding assemblies 88 is two. The ash discharging mechanism 9 includes an opening plate 91. The surface of the opening plate 91 is fixedly installed at the upper position of the inner side surface of the ash discharging cylinder 7. The top of the ash discharging cylinder 7 is fixedly connected with a second lead screw slide 92. The output end of the second lead screw slide 92 is fixedly connected with a stirring assembly 93. The ash discharging mechanism 9 further includes an electric cylinder 94. The top of the electric cylinder 94 is fixedly installed at the bottom of the opening plate 91. The output end of the electric cylinder 94 is fixedly connected with a pushing assembly 96. The inner side surface of the ash discharging cylinder 7 is fixedly connected with an inclined frame 95.

[0049] During use, when the electromagnet 84 is energized, it attracts the magnetic ring 85, making the filter cartridge 6 straight and not easily blown by the wind pressure. At the same time, when the hydraulic cylinder 83 drives the support frame 89 to move up and down, the support frame 89 will magnetically attract the filter cartridge 6 to shake up and down. In cooperation with the air flusher 3 spraying high-pressure gas onto the inner side of the filter cartridge 6, the soot and easily sticky particles on the surface of the filter cartridge 6 are shaken off to the upper position above the perforated plate 91. When the electromagnet 84 is de-energized, the filter cartridge 6 is inspected and repaired. The second lead screw slide 92 drives the stirring assembly 93 to move above the perforated plate 91. The stirring assembly 93 mixes the dust and sticky particles and then drops them to the upper position above the pushing assembly 96. When the electric cylinder 94 controls the pushing assembly 96 to move upward and then push downward, the soot is pushed out of the ash discharge cylinder 7. The guiding of the inclined frame 95 enables the pushing assembly 96 to obstruct the soot particles when resetting, preventing the soot particles from sticking to the inner wall of the ash discharge cylinder 7 and being difficult to discharge, solving the problem that the impurities in the flue gas are easily sticky and agglomerated and deposited at the bottom of the purification equipment and difficult to discharge.

[0050] Fourth Embodiment: As Figure 7 , Figure 8 , Figure 9 shown, the stirring assembly 93 includes an inclined plate 931. The top of the inclined plate 931 is fixedly installed at the output end of the second lead screw slide 92. A second motor 932 is fixedly connected to the lower position on the surface of the inclined plate 931. The stirring assembly 93 further includes an extension roller 933. One end of the extension roller 933 is fixedly installed at the output end of the second motor 932. A spiral blade 934 is fixedly connected to the surface of the extension roller 933. The pushing assembly 96 includes an L-shaped strip 961. The middle position on the surface of the L-shaped strip 961 is slidably installed on the inner side of the inclined frame 95. A chute 962 is formed on the surface of the L-shaped strip 961. The pushing assembly 96 further includes a telescopic rod 963. The telescopic rod 963 is slidably installed on the inner side of the L-shaped strip 961. A connecting strip 964 is slidably connected to the position on the surface of the L-shaped strip 961 near the chute 962. A dust pushing plate 965 is slidably connected to the surface of the connecting strip 964. The top of the dust pushing plate 965 is fixedly installed at the output end of the electric cylinder 94.

[0051] During use, soot and easily sticky particles such as metal particles fall to the upper position above the perforated plate 91. The second lead screw slide 92 drives the inclined plate 931 to reciprocate horizontally, causing the extension roller 933 to reciprocate on the top of the perforated plate 91. While the extension roller 933 moves, the second motor 932 drives it to rotate, and the spiral piece 934 is driven to rotate at the upper position above the perforated plate 91. The soot and particles are stirred and mixed, causing the soot to wrap the easily sticky particles and fall to the lower position below the perforated plate 91. There is a certain distance between the inner side surface of the spiral piece 934 and the extension roller 933, and the soot can pass through the inner side surface of the spiral piece 934 and is not easily adhered to the surface of the spiral piece 934. At this time, the ash pushing plate 965 is located below the surface of the inclined frame 95. The ash pushing plate 965 and the L-shaped strip 961 obstruct the soot particles, and a soot layer is formed at the position between the perforated plate 91 and the ash pushing plate 965. The soot layer ensures that the wind pressure for the flue gas to pass through the filter cartridge 6 is large enough. The wrapping of the particles by the soot can effectively prevent the particles from sticking to the inner side surface of the ash discharge cylinder 7 and being unable to be discharged.

[0052] The fifth embodiment: As Figure 6 , Figure 9 shown, the top end of the extension pipe 871 is fixedly installed at the output end of the first lead screw slide 86. The bottom end of the extension pipe 871 is fixedly installed with an arc-shaped plate 872. The ash scraping assembly 87 further includes a right-angle strip 873. The top end of the right-angle strip 873 is fixedly installed at the upper position on the surface of the extension pipe 871. The bottom of the output end of the first lead screw slide 86 is fixedly connected with an inner sliding ring 874. The middle position on the surface of the L-shaped strip 961 is slidably installed on the inner side surface of the inclined frame 95. A sliding groove 962 is formed on the surface of the L-shaped strip 961. The pushing assembly 96 further includes a telescopic rod 963. The telescopic rod 963 is slidably installed on the inner side surface of the L-shaped strip 961. A connecting strip 964 is slidably connected to the position on the surface of the L-shaped strip 961 close to the sliding groove 962. The ash pushing plate 965 is slidably connected to the surface of the connecting strip 964. The top of the ash pushing plate 965 is fixedly installed at the output end of the electric cylinder 94.

[0053] During use, the extension pipe 871 supports and fixes the right-angle strip 873 and the arc-shaped plate 872. The right-angle strip 873 and the arc-shaped plate 872 are used to scrape the outer side of the air distribution pipe 81. The inner sliding ring 874 scrapes the inner side of the air distribution pipe 81 driven by the first screw slide 86. Under the blowing of the flue gas, the dust particles are not easily adhered to the surface of the air distribution pipe 81. The dust and viscous particles fall to the position above the perforated plate 91. The telescopic rod 963 is slidably installed on the inner side of the L-shaped strip 961. One end of the connecting strip 964 away from the L-shaped strip 961 is slidably installed on the inner side of the ash pushing plate 965. When the ash pushing plate 965 is driven by the electric cylinder 94 to move upward, one end of the connecting strip 964 slides out of the ash pushing plate 965. At the same time, the other end of the connecting strip 964 slides on the inner side of the L-shaped strip 961, and the ash pushing plate 965 is lifted. The dust particles are discharged from the ash discharge cylinder 7 through the position between the ash pushing plate 965 and the L-shaped strip 961. When the ash pushing plate 965 is driven to move downward, the dust particles are intermittently discharged, which can avoid excessive accumulation and caking of dust and blockage, and can also prevent the flue gas from overflowing from the bottom of the ash discharge cylinder 7.
