Description

Technical Field

[0001] This invention relates to the field of dust removal technology, specifically to a high-efficiency dust collector for sintered plates using zoned directional pulse jet cleaning. Background Technology

[0002] Sintered plate dust collectors (also called plastic sintered plate dust collectors) are pulse dust collection equipment that uses rigid polymer sintered plates as filter elements. The core is surface filtration, which is specially designed to solve the difficult dust conditions of bag / filter cartridges being easily clogged, stuck with dust, and blocked.

[0003] During the dust removal process of sintered plates, dust-laden gas passes through the sintered plate, and the dust is trapped on the outer surface of the sintered plate. Pulse gas is sprayed out from the inner cavity of the sintered plate to back-blown the dust attached to the surface, thus completing the dust removal. Due to the large vertical height of the sintered plate, the dust-laden airflow flows upward from the bottom of the plate, resulting in a dust layer on the surface of the sintered plate that is thicker at the bottom and thinner at the top. The pulse back-blowing airflow tends to leak out preferentially from the upper area with less resistance, resulting in insufficient back-blowing impact pressure at the bottom of the sintered plate. The dust attached to the plate surface is difficult to be fully peeled off, thereby reducing the dust removal efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a high-efficiency dust collector for sintered plates with zoned directional pulse jet cleaning, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a high-efficiency dust collector for sintered plates using zoned directional pulse jet cleaning, comprising a main body, a negative pressure fan fixedly connected to the top of the main body, an inspection door hinged to the right side of the main body, and two inspection windows hinged to the side of the main body near the inspection door, and further comprising:

[0007] The cleaning mechanism is installed inside the main body to improve the uniformity of pulse backflushing cleaning.

[0008] The cleaning mechanism includes several telescopic tubes installed inside the main body. The bottom of the telescopic tubes is fixedly connected to a perforated hollow plate, and the perforated hollow plate is connected to the telescopic tubes.

[0009] An auxiliary mechanism is located at the bottom of the porous hollow plate to balance the pulse backflush pressure.

[0010] The auxiliary mechanism includes two flexible layers disposed on the side wall of the air outlet assembly, and several connecting rings are fixedly connected to the bottom of the flexible layers.

[0011] Furthermore, the main body includes:

[0012] The limiting component is installed inside the main body and is used to hold the filter media;

[0013] The connecting component is installed at the bottom of the main body to allow dusty gas to enter and impurity particles to exit.

[0014] Furthermore, the cleanup agencies also include:

[0015] An exhaust assembly is installed on the side wall of the porous hollow plate to allow pulsed backflushing gas to be ejected downwards.

[0016] The fixing component is installed on the outer surface of the telescopic tube.

[0017] Furthermore, the auxiliary mechanisms also include:

[0018] The guide component is installed at the bottom of the perforated hollow plate.

[0019] Furthermore, the limiting component includes a perforated plate fixedly connected inside the main body, with a blowpipe bolted to the top of the perforated plate;

[0020] Several blow pipes have air tanks fixedly connected to their input ends, and the air tanks are fixedly connected inside the main body.

[0021] Two sintering plates are installed at the bottom of the blowpipe, and the sintering plates are bolted to the bottom of the tube sheet.

[0022] Furthermore, the connecting assembly includes a discharge box fixedly connected to the bottom of the main body, and an air inlet is fixedly connected to the side wall of the discharge box.

[0023] Furthermore, several telescopic tubes are arranged in pairs at equal intervals;

[0024] Two telescopic tubes are bolted inside the blow pipe, and the telescopic ends of the telescopic tubes extend into the interior of the sintering plate.

[0025] The air outlet assembly includes several air outlets opened at the bottom of the porous hollow plate, and the several air outlets are arranged in pairs at equal distances.

[0026] The porous hollow plate has a gap between its outer wall and the inner wall of the sintered plate, allowing it to slide up and down along its height inside the sintered plate.

[0027] Several holes in the porous hollow plate isolate the inner cavity of the porous hollow plate, allowing only the plate body to pass through. During filtration, clean gas flows upward through the holes without obstructing normal filtration and ventilation.

[0028] The air outlet extends to the bottom of the porous hollow plate, from which pulsed airflow is ejected downwards, aiming at the lower part of the inner cavity of the sintered plate.

[0029] Furthermore, the fixing component includes two T-shaped plates fixedly connected to the outer surface of the telescopic tube, and several insert rods fixedly connected between the two T-shaped plates, with the insert rods arranged at equal distances in pairs;

[0030] The insertion rod corresponds to the holes in the porous hollow plate.

[0031] Furthermore, the flexible layer is fixedly connected to the outer wall of the T-shaped plate away from the insertion rod;

[0032] The connecting ring is slidably connected to the outer surface of the insertion rod.

[0033] Furthermore, the guide assembly includes three fixing strips fixedly connected to the bottom of the T-shaped plate;

[0034] Several fixed strips are fixedly connected to inclined frame one at the end away from the T-shaped plate, and inclined frame two is fixedly connected to the bottom of inclined frame one;

[0035] The inclined frame one and the inclined frame two are arranged with a wider upper opening and a narrower lower opening. The inclined surfaces of the inclined frame one and the fixing strip can guide the downward-sprayed gas to the inner wall of the sintering plate.

[0036] The present invention has the following beneficial effects:

[0037] 1. In this invention, when a large amount of gas is ejected downward through a porous hollow plate, the resulting jet reaction force will push the porous hollow plate to slide upward. At this time, the porous hollow plate will slide to the upper part of the inner cavity of the sintering plate, and the pulsed airflow will move upward synchronously with the porous hollow plate. The ejected pulsed airflow will sweep across the entire inner cavity of the sintering plate from bottom to top. This can ensure that the lower part of the inner cavity of the sintering plate receives sufficient pulse pressure first, while improving the uniformity of the pulsed backflushing airflow in stripping dust adhering to the surface of the sintering plate and improving dust removal efficiency.

[0038] 2. This invention reduces the leakage of pulsed airflow from the holes of the porous hollow plate itself, ensuring the downward jet intensity of the air outlet, maintaining stable backflush thrust, and reducing the situation where the airflow pushes the porous hollow plate upward under the reaction force of the pulsed jet, resulting in a large initial thrust and a smaller subsequent thrust, which leads to inconsistent endpoints of the upward sliding of the porous hollow plate each time it is ejected. This ensures the consistency of the pulse backflush action and improves the stability and continuity of the dust removal effect.

[0039] 3. In this invention, when the porous hollow plate continues to slide under the reaction force of the jet, the contraction of the telescopic tube driven by the porous hollow plate will cause the inclined frame one and inclined frame two to slide synchronously. When the inclined frame one and inclined frame two slide upward, part of the airflow impacts the inner wall of the sintering plate through the channel between the inclined frame one and inclined frame two; the angle of the inclined plane forms a throttling damping effect on the airflow, slowing down the upward speed of the porous hollow plate. Under the premise of ensuring the intensity of pulse cleaning, it avoids the hollow plate from hitting the tube sheet at too fast an upward speed, thus ensuring the long-term stable filtration of the sintering plate.

[0040] 4. In this invention, when the porous hollow plate and T-shaped plate slide down after the pulsed gas disappears, the deformed flexible layer slides down between the T-shaped plate and the inner wall of the sintered plate, forming a downward pressure on the gas remaining between the sintered plate and the porous hollow plate. This ensures the backlash pressure and strength of the gas penetrating outward in the sintered plate, further enhancing the cleaning strength of the gas backlash in the sintered plate and improving the cleaning efficiency.

[0041] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0056] Please see Figures 1-10 As shown, this invention is a high-efficiency dust collector for sintered plates with zoned directional pulse jet cleaning, including a main body 1. A negative pressure fan 101 is fixedly connected to the top of the main body 1. An inspection door 102 is hinged to the right side of the main body 1. Two inspection windows 103 are hinged to the side of the main body 1 near the inspection door 102. The invention also includes:

[0057] Cleaning mechanism 2 is installed inside the main body 1 to improve the uniformity of pulse backflushing cleaning;

[0058] The cleaning mechanism 2 includes several telescopic tubes 201 installed inside the main body 1. The bottom of the telescopic tubes 201 is fixedly connected to a perforated hollow plate 211, and the perforated hollow plate 211 and the telescopic tubes 201 are connected in a communication manner.

[0060] The auxiliary mechanism 3 includes two flexible layers 301 disposed on the side wall of the air outlet assembly 21, and several connecting rings 302 are fixedly connected to the bottom of the flexible layers 301.

[0061] Entity 1 includes:

[0062] Restriction component 11 is installed inside the main body 1 and is used to carry the filter medium;

[0063] The connecting component 12 is installed at the bottom of the main body 1 to allow dust-laden gas to enter and impurity particles to be discharged.

[0064] Cleanup agency 2 also includes:

[0065] The air outlet assembly 21 is disposed on the side wall of the porous hollow plate 211 and is used to allow the pulse backflushing gas to be sprayed downward.

[0066] Fixing component 22 is installed on the outer surface of telescopic tube 201.

[0067] Auxiliary mechanism 3 also includes:

[0068] Guide component 31 is installed at the bottom of the porous hollow plate 211.

[0069] The limiting component 11 includes a perforated plate 111 fixedly connected inside the main body 1, and a blow pipe 112 is bolted to the top of the perforated plate 111.

[0070] Several blow pipes 112 have air tanks 113 fixedly connected to their input ends, and the air tanks 113 are fixedly connected inside the main body 1.

[0071] Two sintering plates 4 are provided at the bottom of the blow pipe 112, and the sintering plates 4 are bolted to the bottom of the tube sheet 111;

[0072] First, the staff connects the inlet of the air tank 113 to the external pressure tank, bolts the sintering plate 4 to the underside of the tube sheet 111, and then inserts the porous hollow plate 211 into the inner cavity of the sintering plate 4.

[0073] The connecting assembly 12 includes a discharge box 121 fixedly connected to the bottom of the main body 1, and an air inlet 122 fixedly connected to the side wall of the discharge box 121.

[0074] Several telescopic tubes 201 are arranged in pairs at equal intervals;

[0075] Two telescopic tubes 201 are bolted to the inside of the blow pipe 112, and the telescopic ends of the telescopic tubes 201 extend into the inside of the sintering plate 4.

[0076] The air outlet assembly 21 includes a plurality of air outlets 212 formed at the bottom of the porous hollow plate 211, with the plurality of air outlets 212 arranged in pairs at equal distances.

[0077] Among them, a gap is maintained between the outer wall of the porous hollow plate 211 and the inner wall of the sintered plate 4, which can slide up and down along the height inside the sintered plate 4.

[0078] The porous hollow plate 211 has several holes that isolate the inner cavity of the porous hollow plate 211 and only allow the porous hollow plate 211 to pass through. During filtration, the clean gas flows upward through the holes without obstructing normal filtration and ventilation.

[0079] The air outlet 212 extends to the bottom of the porous hollow plate 211, from which the pulsed airflow is ejected downwards and aimed at the lower part of the inner cavity of the sintering plate 4.

[0080] The fixing component 22 includes two T-shaped plates 221 fixedly connected to the outer surface of the telescopic tube 201. A number of insert rods 222 are fixedly connected between the two T-shaped plates 221. The insert rods 222 are arranged in pairs at equal distances.

[0081] The insertion rod 222 corresponds to the hole on the porous hollow plate 211.

[0082] The flexible layer 301 is fixedly connected to the outer wall of the T-shaped plate 221 away from the insertion rod 222;

[0083] The connecting ring 302 is slidably connected to the outer surface of the insertion rod 222.

[0084] The guide component 31 includes three fixing strips 311 that are fixedly connected to the bottom of the T-shaped plate 221;

[0085] Several fixing strips 311 are fixedly connected to one end of the T-shaped plate 221 with a first inclined frame 312, and the bottom of the first inclined frame 312 is fixedly connected to a second inclined frame 313.

[0086] The inclined frame 312 and the inclined frame 313 are arranged with a wider upper opening and a narrower lower opening. The inclined surfaces of the inclined frame 312 and the fixing strip 311 can guide the downwardly sprayed gas to the inner wall of the sintering plate 4.

[0087] The bottom of the porous hollow plate 211 will form a large gap with the inclined frame 312. At the same time, part of the airflow ejected downward through the porous hollow plate 211 will be guided on the inclined surface of the inclined frame 312 to impact the inner wall of the sintering plate 4, ensuring the impact strength of the pulse airflow on the inner wall of the sintering plate 4.

[0088] In use, the staff first connects the inlet of the air tank 113 to the external pressure tank, bolts the sintering plate 4 to the underside of the tube sheet 111, then inserts the porous hollow plate 211 into the inner cavity of the sintering plate 4, then connects the negative pressure fan 101 to the external pipeline, connects the air inlet 122 to the dust-laden gas conveying pipeline, connects the bottom of the discharge box 121 to the dust collection box, and then installs a sensor in the blowpipe 112 located at the top outlet of the sintering plate 4.

[0089] During dust removal operations, the negative pressure fan 101 is started. When the negative pressure fan 101 is working, it will form a negative pressure adsorption force inside the main body 1, causing the dust-laden gas to pass through the sintering plate 4. At this time, the impurities in the gas will be trapped on the surface of the sintering plate 4, while the clean gas will flow upward through the cavity inside the sintering plate 4. When the gas penetration resistance of a certain section of the sintering plate 4 reaches the set threshold, the section will be marked as the area to be cleaned. The other sections will maintain normal filtration. The pulse valve on the air tank 113 of the section will be opened, so that the pulse airflow will form a pulse airflow inside the sintering plate 4, peeling off the dust on the surface of the sintering plate 4. The dust will fall into the discharge box 121 by gravity and be discharged outward, thus realizing the dust removal operation.

[0090] Among them, the porous hollow plate 211 can be made of ultra-high molecular weight polyethylene material, which is lightweight, has good impact resistance and corrosion resistance, is not easy to adhere to dust, and can be easily pushed by the reaction force of the jet.

[0091] When the pulsed airflow is ejected into the sintering plate 4 through the blowpipe 112, the pulsed gas enters the porous hollow plate 211 through the telescopic pipe 201. A large amount of airflow is ejected downward instantaneously through the air outlet 212 opened at the bottom of the porous hollow plate 211, preferentially acting on the lower region of the inner cavity of the sintering plate 4, ensuring the pulse backflushing intensity in the lower region of the sintering plate 4. At the same time, the jet reaction force generated when a large amount of gas is ejected downward through the porous hollow plate 211 will push the porous hollow plate 211 to slide upward. At this time, the porous hollow plate 211 will slide to the upper part of the inner cavity of the sintering plate 4, and the pulsed airflow will move upward synchronously with the porous hollow plate 211. The ejected pulsed airflow will sweep across the entire inner cavity of the sintering plate 4 from bottom to top, which can preferentially ensure that the lower part of the inner cavity of the sintering plate 4 receives sufficient pulse pressure, while improving the uniformity of the pulse backflushing airflow in stripping dust adhering to the surface of the sintering plate 4, and improving dust removal efficiency.

[0092] When the porous hollow plate 211 slides upward under the reaction force of the pulse jet, it drives the telescopic tube 201 to retract step by step. At the same time, during the upward sliding process, the porous hollow plate 211 slides upward between multiple fixing strips 311, and the insertion rod 222 is inserted into the holes on the porous hollow plate 211 for clean gas flow, sealing the holes and reducing the leakage of pulse airflow from the holes of the porous hollow plate 211 itself. This ensures the downward jet intensity of the air outlet 212, maintains the stability of the backflush thrust, and reduces the situation where the airflow pushes the porous hollow plate 211 upward when it slides upward under the reaction force of the pulse jet, resulting in a large thrust at the beginning and a smaller thrust thereafter, which would cause the endpoint position of the porous hollow plate 211 to slide upward inconsistently each time it is sprayed. This ensures the consistency of the pulse backflush action and improves the stability and continuity of the dust removal effect.

[0093] When the pulsed airflow pushes the porous hollow plate 211 upward, a large gap will be formed between the bottom of the porous hollow plate 211 and the inclined frame 312. At the same time, part of the airflow ejected downward through the porous hollow plate 211 will be guided by the inclined surface of the inclined frame 312 to impact the inner wall of the sintering plate 4, ensuring the impact strength of the pulsed airflow on the inner wall of the sintering plate 4. Meanwhile, as the porous hollow plate 211 continues to slide under the reaction force of the jet, the porous hollow plate 211 pushes the telescopic tube 2 The contraction of 01 will cause the inclined frame 1 312 and inclined frame 2 313 to slide synchronously. When the inclined frame 1 312 and inclined frame 2 313 slide upward, part of the airflow impacts the inner wall of the sintering plate through the channel between the inclined frame 1 312 and inclined frame 2 313. The angle of the inclined plane forms a throttling damping effect on the airflow, which slows down the upward sliding speed of the porous hollow plate 211. Under the premise of ensuring the intensity of pulse cleaning, it avoids the hollow plate from hitting the tube sheet 111 at too fast an upward speed, thus ensuring the long-term stable filtration of the sintering plate.

[0094] When the porous hollow plate 211 slides upward and the insertion rod 222 is inserted into the hole on the porous hollow plate 211, the top outer wall of the porous hollow plate 211 will squeeze the connecting ring 302. After being squeezed, the connecting ring 302 will slide upward on the surface of the insertion rod 222 and push the fixing strip 311, causing the fixing strip 311 to bulge outward and deform. When the flexible layer 301 deforms outward, the flexible layer 301 will fill the channel between the inner wall of the sintered plate 4 and the T-shaped plate 221. Then, when the porous hollow plate 211 and the T-shaped plate 221 slide down after the pulse gas disappears, the deformed flexible layer 301 slides down between the T-shaped plate 221 and the inner wall of the sintered plate 4, forming a downward pressure on the gas remaining in the sintered plate 4 and between the porous hollow plate 211. This ensures the back pressure and strength of the gas penetrating outward in the sintered plate 4, further enhancing the cleaning strength of the gas backflow in the sintered plate 4 and improving the cleaning efficiency.
