Description

Technical Field

[0001] The invention relates to the technical field of bag-type flue gas dust removal, and more particularly to a bag-type flue gas dust collector. Background Art

[0002] In the prior art, bag filter is an important industrial flue gas treatment equipment, which is widely used in various industrial production processes. It captures dust and particles in the flue gas through filter bags, effectively reducing environmental pollution. However, this equipment faces some problems and challenges in actual use, especially in the installation and replacement of filter bags, and the uniformity of flue gas filtration.

[0003] First, regarding the installation and replacement of filter bags, since the working environment of bag-type dust collectors is often high in temperature and contains a large amount of dust, the filter bags will wear out or even be damaged after long-term use, which requires regular replacement of filter bags to ensure dust removal efficiency. However, the existing bag-type dust collector design has certain inconveniences in replacing filter bags. In some designs, the installation and replacement of filter bags requires a lot of manual operation, which is not only time-consuming and labor-intensive, but may also require special tools or equipment. In addition, in order to replace the internal filter bags, the operator may need to enter the dust collector, which not only increases the difficulty of the work, but also may pose a safety risk.

[0004] Secondly, regarding the uniformity of flue gas filtration, existing bag-type dust collectors have certain limitations in the design of flue gas intake. Normally, flue gas enters the dust collector from one direction, which causes the filter bags close to the air inlet to be exposed to a large amount of flue gas and dust first, thereby accumulating dust more quickly. The filter bags far from the air inlet may be exposed to less dust, resulting in uneven filtration effect. This uneven filtration effect not only affects the overall efficiency of the dust collector, but may also cause some filter bags to be damaged prematurely, while other filter bags are not fully utilized. In addition, when the filter bags close to the air inlet are blocked due to excessive dust accumulation, it may cause the distribution pressure of the flue gas to increase, thereby affecting the overall operating stability of the dust collector.

The tube 19 is provided with a plurality of insertion tubes 20, each of which is provided with a plurality of air outlet holes 21, each of which is inserted into the frame 17, an air storage tank 22 and an air outlet pipe 23 are provided on the air outlet frame 2, and an intermediate tube 24 is provided on each transverse tube 19, the intermediate tube 24 is connected to the air storage tank 22, one end of the air outlet pipe 23 is connected to the air outlet frame 2, and the other end of the air outlet pipe 23 is connected to external equipment, and a plurality of cover plates 25 are provided on the air outlet frame 2, and each cover plate 25 is respectively clamped on the air outlet frame 2.

[0040] Working principle: When filtering the smoke, the smoke first enters the inner cavity 30 through the air inlet pipe 29, and then is discharged from the gap between the gas adjustment hole 32 and the fixed hole 31. At this time, the smoke enters the interior of the dispersion chamber 26, and then the smoke is pressed on the telescopic part 15 so that the telescopic part 15 is concave inward, thereby completing the filtering process. The filtered smoke is discharged into the air outlet frame 2 through the middle part and discharged through the air outlet pipe 23.

[0041] When the filter bag needs to be replaced, the operator first contracts the multiple elastic sheets 6 at the upper end of the top plate 3 to move it in the direction of the axis, thereby driving the toggle rod 7 to rotate, and the toggle rod 7 slides along the wave groove 12. At this time, the toggle rod 7 expands outward and rises in the vertical direction relative to the position of the block 10. The block 10 is driven to move upward under the action of the tension spring 9, thereby releasing the clamping connection between the lateral groove 13 and the clamping ring 11, and then the clamping ring 11 can be taken out, thereby completing the removal of the multiple telescopic parts 15, and then the new filter bag is sleeved on the frame 17, the connecting ends of the multiple telescopic parts 15 are fitted on the frame 17, and the bottom sleeve 18 is sleeved on the bottom ring 16, and then the clamping ring 11 is inserted into the block 10. At this time, the block 1 0 is still in a state of being pulled upward, so it can be fixed. When dust removal is performed, since air is taken in from the outside to the inside, the multiple telescopic parts 15 will be recessed inward, and then the gas will blow upward. At this time, since the gas is blown upward, it will first contact the multiple elastic sheets 6, and then the multiple elastic sheets 6 will have a tendency to expand outward, and then drive the toggle rod 7 to shrink toward the axis. Therefore, the position of the toggle rod 7 relative to the card block 10 will be downward, and a downward force will be applied to the card block 10, and then the clamping force will be turned to the outside under the action of the inclined cone 8, and then the lateral groove 13 will abut against the clamping ring 11. Since the length of the toggle rod 7 on the elastic sheet 6 is much greater than the length at the lower end, the strength of the toggle rod 7 at the lower end is greatly amplified, thereby providing a larger clamping force to ensure the stability of the clamping.

[0042] When pulse dust blowing is performed, the gas storage tank 22 releases high-pressure gas and discharges it through the multiple air outlets 21 on the insertion tube 20, and then pulse dust removal is performed on the telescopic part 15. Since the multiple telescopic parts 15 will be concave inwards during dust removal, the telescopic parts will be in a concave state before pulse dust removal, and then the multiple telescopic parts 15 will be squeezed outwards by the high-pressure gas, so they will be in a rapid expansion state, so that the telescopic part 15 is in an expanded state from the concave state. The speed at this time is very large, so it will produce great vibration, thereby improving the dust removal efficiency. The effect of dust removal is achieved, and when pulse dust removal is performed, the gas will first be discharged from the air outlet 21 at the uppermost end, so the elastic sheet 6 will be subjected to the thrust of expansion, so that the toggle rod 7 is in a contracted state, so that the clamping block 10 and the clamping ring 11 are pre-clamped. When the clamping ring 11 is subjected to the downward force, the clamping block 10 will be driven downward more, and the clamping block 10 will provide a clamping force to the clamping ring 11 more downward, and since the upper end of the toggle rod 7 is much longer than the lower end, there will be a large torque stuck on the clamping block 10, thereby ensuring the stability of the clamping ring 11.

[0043] After a pulse dust removal is completed, the dust will fall into the collection shell 40, and then the discharge valve 41 is opened to discharge the dust, thereby completing the dust discharge process.

[0044] See also Figure 10 to Figure 13 , the support frame 1 is provided with an adjustment mechanism, the adjustment mechanism includes a dispersion chamber 26, an annular ring 27, an adjustment disk 28 and an air inlet pipe 29, the dispersion chamber 26 is installed on the support frame 1, the air outlet frame 2 is connected to the dispersion chamber 26, an inner cavity 30 is provided in the dispersion chamber 26, a plurality of annular rings 27 are provided, and the plurality of annular rings 27 are respectively and equidistantly installed in the dispersion chamber 26, each dispersion chamber 26 is rotatably connected to the adjustment disk 28, a plurality of fixing holes 31 are provided on the annular ring 27, a plurality of adjustment holes 32 are provided on the adjustment disk 28, one end of the air inlet pipe 29 is connected to the inner cavity 30, and the other end of the air inlet pipe 29 is connected to the air inlet device, and the adjustment A diffusion sleeve 33 is coaxially provided on the section disk 28, and a plurality of diffusion strips 34 are provided on the surface of the diffusion sleeve 33, and each diffusion strip 34 is respectively aligned with its adjustment hole 32, and an adjustment column 35 is coaxially provided on the adjustment disk 28, and an adjustment rod 36 is provided on the adjustment column 35, and a plurality of indicator blocks 37 are provided on the dispersion chamber 26, and a nut 38 is threadedly provided on the adjustment column 35, and a resistance disk 39 is slidably provided on the adjustment column 35, and one side of the resistance disk 39 is affixed to the diffusion chamber, and the other side of the resistance disk 39 is affixed to the nut 38, and a collecting shell 40 is provided on the support frame 1, and a discharge valve 41 is provided on the collecting shell 40, and the collecting shell 40 is connected to the dispersion chamber 26.

[0045] Working principle: the air inlet pipe 29 first passes the gas into the inner cavity 30, and then the gas can circulate around the inner cavity 30, and then the rotation of the adjustment rod 36 will drive the rotation of the adjustment column 35, and the nut 38 will abut on the abutment plate 39, and the abutment plate 39 will press on the side of the dispersion chamber 26, so that the sealing effect can be guaranteed. The rotation of the adjustment plate 28 can drive the multiple adjustment holes 32 and the fixed holes 31 to adjust their positions. During the adjustment, the position of the adjustment rod 36 can be indicated by the indicator block 37, thereby ensuring the convenience of adjustment, thereby changing the gas output. Since only one-side air intake will cause the telescopic part close to the air inlet pipe 29 to be 15 will filter more smoke, and the amount filtered at a position far away from the air inlet pipe 29 is lower, which will cause unevenness, and may also cause unevenness up and down. The air intake volume at each location can be adjusted by adjusting the positions of the adjusting holes 32 and the fixed holes 31 on the multiple adjusting disks 28, thereby reducing the uneven filtering on one side, and when the smoke passes through the adjusting holes 32 and blows onto the diffusion sleeve 33, the direction of the air intake will be changed, so that it avoids the situation where resistance is generated by blowing against each other in the multiple adjusting holes 32, thereby ensuring the uniformity of the blowing, and the filtered smoke is discharged through the air outlet frame 2 and the air outlet pipe 23, thereby completing the dust removal process.

[0046] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which will not be described one by one here. In the above, all fixed connections are preferably welded.
