Description

Technical Field

[0001] The present invention relates to the technical field of dust removal equipment, and in particular to a filter cartridge dust collector with a synergistic dust cleaning function and a dust removal method. Background Art

[0002] A large amount of dust is generated during the industrial and mining production process, which poses potential hazards to the surrounding environment and human body. Dust removal must be carried out to reduce the dust concentration in industrial and mining workplaces. Among them, dry dust removal is to discharge dust in a dry form. Because of its simple structure, low use requirements, and conducive to centralized dust treatment and comprehensive utilization, it is widely used in industrial and mining dust removal places such as mechanical casting and coal preparation.

[0003] For workplaces with high dust concentration, the filter cartridges collect dust too quickly and cleaning becomes very frequent, which shortens the service life of the filter cartridges and increases the operating cost of the dust removal device. In addition, the dust particle settling rate during the pulse jet cleaning process is slow, and high-concentration dust permeates the dust removal system, which not only reduces the dust removal efficiency, but is also prone to explosion, increasing the safety risks of the dust removal system.

[0005] In order to achieve the above-mentioned object, the present invention provides a filter cartridge dust collector with a synergistic cleaning function, comprising a dust collector housing, an induced boost pulse blowing device and a vibration-assisted cleaning filter cartridge installed in the dust collector housing; the induced boost pulse blowing device is located at the upper part of the vibration-assisted cleaning filter cartridge, and is used to eject high-speed airflow pulses to clean the dust accumulated inside the dust collector;

[0006] The induced boost pulse jet device comprises an air delivery pipe, a nozzle support frame, an upper cover, a first-stage reducer, a nozzle support body, a connecting nut and a second-stage reducer; the air delivery pipe is arranged in the dust collector box and is connected to a branch nozzle;

[0007] The end of the branch nozzle away from the gas delivery pipe is inserted into the upper cover body through the top wall opening of the upper cover body, and the inner diameter of the top wall opening of the upper cover body is larger than the outer diameter of the branch nozzle, so that a first annular gap air inlet hole is left at the connection between the branch nozzle and the upper cover body;

[0008] One end of the upper cover body away from the branch nozzle is inserted into the nozzle support body; the nozzle support body is connected and fixed to the nozzle support frame, and the nozzle support frame is fixed to the outer wall of the gas delivery pipe;

[0009] The first-stage reducer is inserted into the nozzle support body, and the top end of the first-stage reducer is hooked on the inner step surface of the nozzle support body; the inner diameter of the first-stage reducer decreases in the direction away from the nozzle support body; one end of the nozzle support body away from the upper cover body is inserted into the connecting nut and connected to the inner wall nut of the connecting nut;

[0012] Furthermore, the guide body includes a guide base, a contracted neck and a guide head which are integrally connected and fixed. The guide base is fixed to the inner bottom surface of the filter cartridge. The guide base and the guide head are both truncated cone-shaped, and their outer diameters increase in the direction away from the induced boost pulse injection device. The top of the guide head forms a hemispherical surface.

[0013] Furthermore, two vibrating plates are hinged on the shrinking neck, and the two vibrating plates are symmetrically arranged on both sides of the shrinking neck. A spring rope is fixedly connected to the upper surface of each vibrating plate, and one end of the spring rope away from the vibrating plate is fixedly connected to the bottom side of the outer wall of the guide head.

[0014] Furthermore, the arc ring adopts a hollow design, and the arc ring is composed of two arc-shaped tubes, and a gap is left between the ends of the two arc-shaped tubes.

[0015] Furthermore, a plurality of annular dust collecting baffles are sleeved on the outer side of the vibration-assisted dust cleaning filter cartridge, and the annular dust collecting baffles are evenly arranged along the height direction of the filter cartridge, and the annular dust collecting baffles are designed as a circular ring with an outer diameter gradually decreasing from top to bottom;

[0016] The annular dust collecting baffle includes an inclined groove baffle and an annular pleated filter; the inclined groove baffle is located on the outside of the annular pleated filter, and the inclined groove baffle is composed of a first vertical baffle, an inclined baffle and a second vertical baffle connected in sequence, and works together with the annular pleated filter to form a dust collecting cavity.

[0017] Furthermore, a plurality of supporting columns are arranged on the inner side of the annular dust collecting baffle, and the plurality of supporting columns are evenly distributed along the circumference of the annular dust collecting baffle; each annular dust collecting baffle is fixedly connected to the supporting columns; the supporting columns are hollow tubes, and the outer wall of the supporting columns is provided with blowing holes at positions corresponding to the dust collecting cavities formed by each inclined groove baffle and the annular pleated filter, and the top end of the supporting column is connected to a blowing channel.

[0018] Furthermore, an atomization device is provided on the outer side of the annular dust collecting baffle, and the atomization device includes a condensation net and a water mist baffle.

A negative pressure port for installing the negative pressure device is opened at the bottom of the side wall of the dust collector case. The filter is fixed at the negative pressure port. The negative pressure fan is located on the side of the filter away from the dust collector case. The mounting tube is fixedly connected to the outer wall of the dust collector case at the negative pressure port. The negative pressure fan is rotatably connected in the mounting tube, and the negative pressure fan has forward and reverse functions to adapt to different working requirements. The pressure controller is fixed in the mounting tube and electrically connected to the negative pressure fan.

[0020] The present invention also provides a dust cleaning and dust removal method for a filter cartridge dust collector with a synergistic dust cleaning function, using the filter cartridge dust collector with a synergistic dust cleaning function;

[0021] When the dust collector is performing adsorption dust removal, the induced draft fan connected to the air inlet draws the dust-laden airflow into the air inlet of the dust collector box and moves toward the vibration-assisted dust-cleaning filter cartridge; the dust-laden airflow first contacts the annular dust collecting baffle, and some dust particles are captured and adsorbed by the annular pleated filter screen; the remaining dust particles that cannot be captured by the annular pleated filter screen move between the intervals of each annular dust collecting baffle to the filter material surface of the vibration-assisted dust-cleaning filter cartridge, and then further adsorb and remove the dust particles in the dust-laden gas;

[0022] When it is necessary to clean the dust inside the dust collector, the high-speed jet airflow enters the induced boost pulse jet device through the air pipe. The high-speed jet airflow first enters the cavity composed of the upper cover, the first-level reducer and the nozzle support body, and then generates negative pressure to form a first-level induced airflow boost; the jet airflow increases the jet flow through the induced airflow, and then accelerates the airflow through the first-level reducer; the jet airflow that completes the first-level boost acceleration flows from the first-level reducer into the second-level reducer, and the flow of the high-speed airflow also generates negative pressure in the cavity of the second-level reducer. The external airflow is forced to enter the secondary reducer through the second annular slit air inlet hole on the secondary reducer, and then the secondary induced airflow merges with the primary induced airflow to complete the secondary boost acceleration of the jet airflow, and finally sprays from the secondary reducer to the vibration-assisted cleaning filter cartridge; under the guidance of the guide body, the high-speed jet airflow is sprayed toward the vibration plate, and under the impact of the jet airflow, the vibration plate beats the arc ring downward to generate vibration and transmit it to the hollow circular tube, and then drives the filter cartridge to vibrate through the hollow circular tube, shaking off and removing the dust particles attached to the outer surface of the filter cartridge;

[0023] At the same time, the blowing channel in the annular dust collecting baffle also introduces the blowing airflow into the supporting column, and the blowing airflow enters the dust collecting cavity formed by the inclined groove baffle and the annular pleated filter through the blowing hole, completing the cleaning of the dust particles attached to the annular pleated filter.

[0024] Part of the dust particles sprayed down from the filter cartridge and the annular pleated filter screen will fall on the inclined groove baffle and slide into the atomization device by gravity and be discharged in the form of muddy water; another part of the dust particles that cannot be captured by the atomization device will sink quickly under the action of the negative pressure device, most of the dust particles will mix with the muddy water at the bottom of the dust collector box, and the remaining small part of the dust particles will be captured by the filter screen of the negative pressure device; the muddy water gathered at the bottom of the dust collector box is discharged and regulated through the drainage device;

[0025] In addition, when the dust collector is performing adsorption dust removal, the negative pressure device can perform backblowing to clean the dust particles attached to the filter; the induced draft fan connected to the air inlet only operates during the adsorption dust removal stage, and the negative pressure device only operates during the cleaning stage to extract airflow and backblow to clean the circular filter.

[0026] Beneficial effects of the present invention:

[0027] The filter cartridge dust collector with a synergistic cleaning function of the present invention is provided with an induced pressurized pulse blowing device. A high-speed jet airflow passes through the induced pressurized pulse blowing device to form a negative pressure in its internal cavity, thereby inducing the external airflow to enter the pulse blowing device through the first annular gap air inlet hole and the second annular gap air inlet hole, thereby effectively enhancing the blowing speed and pressure of the jet airflow, thereby improving the jet cleaning effect.

[0028] By setting up a vibration-assisted cleaning filter cartridge, a high-speed pulse jet airflow drives the vibration plate to vibrate and strike the arc ring, and transmits the vibration force to the hollow circular tube. The vibration is then extended to the entire filter cartridge through the resonance effect of the hollow circular tube, removing dust particles attached to the filter material, thereby maintaining the filter cartridge in good working condition and improving the filtration efficiency.

[0029] By setting up an annular dust collection baffle, which cooperates with the vibration-assisted cleaning filter cartridge, a multi-stage dust removal and filtration effect is achieved in the dust removal stage, ensuring that most of the dust in the final airflow is effectively removed; the dust removal process ensures that the dust collector can perform dust removal efficiently and stably through the synergistic effect of the two, ensuring the normal operation of the equipment and the continuous purification of the air quality.

DETAILED DESCRIPTION

[0042] The present invention is further described in detail below in conjunction with the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0043] The invention discloses a filter cartridge dust collector with a synergistic dust cleaning function.

[0044] Reference Figure 1 and Figure 2 , a filter cartridge dust collector with a synergistic cleaning function, comprising an induced boost pulse jet device 1, a vibration-assisted cleaning filter cartridge 2, an annular dust collecting baffle 3, a negative pressure device 4, a dust collector box 5, an atomizing device 6 and a drainage device 7; wherein, the induced boost pulse jet device 1, the vibration-assisted cleaning filter cartridge 2, the annular dust collecting baffle 3 and the atomizing device 6 are all installed in the dust collector box 5, and an air inlet 52 and an air outlet 51 are provided on the outer side wall of the dust collector box; the negative pressure device 4 and the drainage device 7 are installed at the bottom of the side wall of the dust collector box 5; the induced boost pulse jet device 1 is located at the top of the vibration-assisted cleaning filter cartridge 2, the annular dust collecting baffle 3 is arranged on the outer side of the vibration-assisted cleaning filter cartridge 2, and the atomizing device 6 is located on the outer side of the annular dust collecting baffle 3.

[0045] Reference Figure 3 and Figure 4 The induced boost pulse jet device 1 is installed on the upper part of the dust collector housing 5, and is used to eject high-speed airflow pulses to clean the dust inside the dust collector. The induced boost pulse jet device 1 includes an air supply pipe 11, a nozzle support frame 12, an upper cover body 13, a first-stage reducer 14, a nozzle support body 15, a connecting nut 16 and a second-stage reducer 17. A jet installation hole 54 is opened at the top of the outer wall of the dust collector housing, and the air supply pipe 11 is passed through the jet installation hole 54 from the outside to the dust collector housing 5 and is connected to a branch nozzle 111.

[0046] Reference Figure 3 and Figure 4 The end of the branch nozzle 111 away from the gas pipe 11 is passed through the top wall opening of the upper cover body 13 and is arranged in the upper cover body 13, and the inner diameter of the top wall opening of the upper cover body 13 is larger than the outer diameter of the branch nozzle 111, so that a first annular seam air inlet hole 18 is left at the connection between the branch nozzle 111 and the upper cover body 13; the end of the upper cover body 13 away from the branch nozzle 111 is passed through the nozzle support body 15; the two sides of the nozzle support body 15 are connected to the nozzle support frame 12 by bolts, and corresponding connecting holes 19 for the bolts to pass through are opened on the nozzle support body 15 and the nozzle support frame 12, and the nozzle support frame 12 is welded and fixed to the outer wall of the gas pipe 11. The first-stage reducer 14 is passed through the nozzle support body 15, and the top end of the first-stage reducer 14 is hung on the inner step surface of the bottom end of the nozzle support body 15; the inner diameter of the first-stage reducer 14 decreases in the direction away from the nozzle support body 15; the end of the nozzle support body 15 away from the upper cover body 13 is passed through the connecting nut 16 and is connected to the inner wall nut of the connecting nut 16; the top end of the second-stage reducer 17 is sleeved outside the first-stage reducer 14, and the top end of the second-stage reducer 17 is passed through the connecting nut 16 and is threadedly connected to the inner wall of the connecting nut 16; the outer circumferential surface of the second-stage reducer 17 is provided with a second annular gap air inlet hole 110, and the second annular gap air inlet hole 110 is composed of two arc-shaped air inlet holes.

[0047] The high-speed jet airflow enters through the air delivery pipe 11 and quickly enters the interior of the induced pressurized pulse jet device 1; the high-speed jet airflow first enters the cavity formed by the upper cover 13, the first-stage tapered pipe 14 and the nozzle support 15, causing negative pressure to form in the cavity. This negative pressure phenomenon can induce the external airflow to enter the cavity through the first annular gap air inlet 18 between the air delivery pipe 11 and the upper cover 13, thereby further enhancing the pressure of the jet airflow.

[0048] Subsequently, the primary induced airflow and the high-speed injection airflow will flow from the primary reducer 14 into the secondary reducer 17. At this time, the high-speed airflow flows through the inside of the secondary reducer 17, causing negative pressure to form inside the secondary reducer 17, which then causes the external airflow to enter the secondary reducer 17 through the second annular gap on the secondary reducer 17, and then the secondary induced airflow merges with the primary induced airflow, further increasing the flow rate and velocity of the injection airflow, thereby greatly improving the injection capacity of the pulse injection device.

[0049] Reference Figure 3 and Figure 4 In order to ensure the tight connection and stable operation of each component, the connecting nut 16 firmly connects the nozzle support body 15 and the secondary reducer 17. At the same time, the upper cover 13 and the primary reducer 14 are assembled into the step groove of the nozzle support body 15 to ensure the stability of each component inside the device. The bolted connection between the nozzle support body 15 and the nozzle support frame 12 ensures the overall firmness of the device and the smoothness of the airflow channel, further enhancing the working effect and safety of the spraying system.

[0050] Reference Figures 5 to 7 A mounting plate 55 is horizontally welded and fixed in the dust collector housing 5, and a slot 56 for installing the vibration-assisted dust-cleaning filter cartridge 2 is provided in the middle of the mounting plate 55. The vibration-assisted dust-cleaning filter cartridge 2 includes a filter cartridge 26, a plurality of hollow circular tubes 21, an arc ring 24, and a guide body 22; the hollow circular tubes 21, the arc ring 24, and the guide body 22 are all located inside the filter cartridge 26, and the filter cartridge 26 is inserted into the mounting plate 55 through the slot 56, and the top end of the filter cartridge 26 is hung and bolted to the mounting plate 55.

[0051] Reference Figures 5 to 7 The hollow circular tube 21 is vertically arranged on the inner filter surface of the filter cartridge 26. In this embodiment, four hollow circular tubes 21 are provided and evenly distributed along the circumference of the filter cartridge 26. The outer wall of the hollow circular tube 21 is fitted and fixed to the inner filter surface of the filter cartridge 26. The upper and lower ends of each hollow circular tube 21 are 10 mm away from the top and bottom of the filter cartridge 26 to ensure that the hollow circular tube 21 can be stably fixed in the filter cartridge 26 without affecting the functions of its components during the cleaning process.

[0052] Reference Figures 5 to 7 The arc ring 24 is coaxially arranged with the filter cartridge 26, and the arc ring 24 is located in the middle of each hollow circular tube 21. The outer wall of the arc ring 24 is fixedly connected to the four hollow circular tubes 21. The arc ring 24 is composed of two arc-shaped tube bodies, and the ends of the two arc-shaped tube bodies are separated by a gap of 15 mm. The arc ring 24 also adopts a hollow design, so that it can vibrate under the impact of high-speed pulse jet airflow, and can effectively transmit the vibration force to the hollow circular tube 21. The design of the arc ring 24 can not only enhance the conduction effect of vibration, but also improve the vibration efficiency in the entire cleaning process, making the cleaning more thorough.

[0053] Reference Figures 5 to 7 The guide body 22 includes a guide base 221, a contraction neck 222 and a guide head 223 which are integrally connected and fixed. The guide base 221 is fixed on the inner bottom surface of the filter cartridge 26. The guide base 221 and the guide head 223 are both truncated cone-shaped, and the outer diameters of both increase in the direction away from the induced boost pulse jet device 1, and the inclination angle of the outer walls of both relative to the horizontal plane is 75°; the top of the guide head 223 forms a hemispherical surface; the design of the guide body 22 ensures that the pulse jet airflow can obtain the best dispersion and guide effect, avoids excessive concentration of the airflow, thereby improving the utilization efficiency of the airflow and the cleaning effect. The inclination angle of the guide body 22 accurately controls the directionality of the airflow, so that the pulse jet airflow in the entire cleaning process can act on the filter cartridge 26 more evenly and efficiently, thereby better achieving the purpose of removing dust accumulation and increasing the service life of the filter element.

[0054] Reference Figures 5 to 7 Two rapping plates 25 are hinged on the contraction neck 222, and the two rapping plates 25 are symmetrically arranged on both sides of the axial direction of the contraction neck 222. A spring rope 23 is fixedly connected to the upper surface of each rapping plate 25, and one end of the spring rope 23 away from the rapping plate 25 is fixedly connected to the bottom side of the outer wall of the guide head 223. Under the action of the high-speed pulse jet airflow, the rapping plate 25 can vibrate up and down and knock the arc ring 24, so that the arc ring 24 vibrates, and transmits the vibration force to the hollow circular tube 21, and then the vibration is extended to the whole filter cartridge 26 through the resonance of the hollow circular tube 21; these vibration fluctuations help remove dust particles attached to the filter material, thereby maintaining the good working condition of the filter cartridge 26 and improving the filtering efficiency.

[0055] Reference Figure 8 and Fig. 9 A number of annular dust collecting baffles 3 are provided, and the annular dust collecting baffles 3 are evenly arranged along the height direction of the filter cartridge 26. The annular dust collecting baffles 3 adopt a circular ring design with an outer diameter gradually decreasing from top to bottom. The inner diameter of the annular dust collecting baffle 3 is slightly larger than the vibration-assisted cleaning filter cartridge 2. The annular dust collecting baffle 3 is sleeved on the outer side of the vibration-assisted cleaning filter cartridge 2 to form an effective filtering space.

[0056] The annular dust collecting baffle 3 includes an inclined groove baffle 32 and an annular pleated filter 33; the inclined groove baffle 32 is located on the outside of the annular pleated filter 33, and the inclined groove baffle 32 is composed of a first vertical baffle 321, an inclined baffle 322 and a second vertical baffle 323 connected in sequence, and works together with the annular pleated filter 33 to form a dust collecting cavity, which effectively blocks the entry of dust particles.

[0057] In order to enhance the structural stability of the annular dust collecting baffle 3, a supporting column 34 is provided on the inner side of the annular dust collecting baffle 3. In the present embodiment, four supporting columns 34 are provided, which are evenly distributed along the circumference of the annular dust collecting baffle 3; each annular dust collecting baffle 3 is fixedly connected to the supporting column 34, thereby improving the stability of the overall structure.

[0058] The support column 34 is a hollow tube, and the outer wall of the support column 34 is provided with blowing holes 35 at the positions corresponding to the dust collecting cavities formed by the inclined groove baffles 32 and the annular pleated filter screen 33. The top end of the support column 34 is connected to the blowing channel 31, thereby forming a system structure similar to pulse jet cleaning, which is convenient for the subsequent removal of dust on the annular pleated filter screen 33.

[0059] The inclined groove baffle 32 is inclined at 30° relative to the horizontal plane. When the vibration-assisted cleaning filter cartridge 2 and the annular dust collecting baffle 3 work together to clean the dust, the dust on the annular pleated filter screen 33 is cleaned and falls to the upper surface of the clamping groove baffle of the next layer. Due to the inclined setting of the inclined groove baffle 32, the dust particles slide downward along the inclined angle under the action of gravity, and are further processed and discharged through the atomizing device 6 arranged on the outside, preventing the particles from entering the filtration system again.

[0060] During the operation of the dust collector, the dust-laden airflow enters from the air inlet 52. As the airflow flows, most of the dust particles in the dust-laden airflow will first be captured and adsorbed by the annular pleated filter 33. The dust particles that are not effectively captured in the first filtering stage will enter the vibration-assisted dust cleaning filter cartridge 2, and will be further adsorbed and removed by the filter cartridge 26, ensuring that most of the dust in the final airflow is effectively removed. The dust removal process ensures that the dust collector can perform dust removal efficiently and stably through the synergistic effect of the two, ensuring the normal operation of the equipment and the continuous purification of air quality.

[0061] Reference Fig.10 , the atomizing device 6 is arranged on the outer side of the annular dust collecting baffle 3 on all sides, the atomizing device 6 includes a condensation net 63 and a water mist baffle 61, and a water mist inlet 62 for supplying water mist is opened on the dust collector box 5. The water mist of the water mist inlet 62 is a straight-discharge type of water mist supply. The water mist baffle 61 is arranged on one side of the water mist inlet 62 and is welded and fixed on the bottom surface of the mounting plate 55. The setting of the water mist baffle 61 can prevent the water mist from directly and straightly moving toward the vibration-assisted dust-cleaning filter cartridge 2. When the vibration-assisted dust-cleaning filter cartridge 2 and the annular dust collecting baffle 3 are cleaned, the dust particles blown off will stay on the inclined groove baffle 32 and move to the atomizing device 6 arranged around by gravity; the dust particles moving to the atomizing device 6 will fall on the condensation net 63, and the water mist particles and condensed water droplets thereon will adsorb these dust particles, accelerating the removal of dust particles.

[0062] Reference Figure 1 and Figure 2 A portion of the dust particles sprayed from the filter cartridge 26 and the annular pleated filter screen 33 will fall on the inclined groove baffle 32 and slide into the atomizing device 6 by gravity, and be discharged in the form of muddy water. Two muddy water baffles 57 are fixed in the dust collector housing 5. The two muddy water baffles 57 are symmetrically arranged and tilted downward. The muddy water baffles 57 play a buffering and diverting role for the muddy water formed by the dust adsorbed by the atomizing device 6. A drainage port 53 is provided at the bottom of the dust collector housing 5. The drainage port 53 is connected to a drainage device 7, and the drainage device 7 is used to discharge the muddy water.

[0063] Reference Figure 1 The drainage device 7 includes a drainage pipe, a water pump and a liquid level sensor. The drainage pipe is connected to the inside of the dust collector box 5 through a drainage port 53. The water pump is installed on the drainage pipe. The liquid level sensor is installed at the bottom of the side wall of the dust collector box 5 to detect the liquid level of the muddy water. The liquid level sensor is electrically connected to the water pump. When there is too much muddy water in the dust collector box 5, the liquid level sensor is triggered, and the liquid level sensor transmits a signal to the water pump, thereby discharging the muddy water in the dust collector box 5.

[0064] Reference Fig.11 The negative pressure device 4 includes a negative pressure fan 42, a filter 43, a pressure controller 41 and a mounting pipe 44; a negative pressure port 58 for mounting the negative pressure device 4 is provided at the bottom of the side wall of the dust collector housing 5, the filter 43 is fixed at the negative pressure port 58, the negative pressure fan 42 is located on the side of the filter 43 away from the dust collector housing 5, the mounting pipe 44 is fixedly connected to the outer wall of the dust collector housing 5 at the negative pressure port 58, the negative pressure fan 42 is rotatably connected in the mounting pipe 44, and the negative pressure fan 42 has a forward and reverse rotation function to meet different working requirements. The pressure controller 41 is fixed in the mounting pipe 44 and is electrically connected to the negative pressure fan 42.

[0065] In normal working mode, the negative pressure fan 42 generates negative pressure by extracting the airflow in the dust collector. The negative pressure effect can effectively promote the sedimentation of dust particles in the dust collector and ensure the dust removal efficiency of the system. However, as time goes by and the workload increases, dust particles will accumulate on the surface of the filter 43, resulting in a decrease in the ventilation performance of the filter 43, thereby increasing the pressure difference between the negative pressure fan 42 and the filter 43. At this time, the pressure controller 41 will detect the change in pressure, identify the blockage of the filter 43, and promptly start the reversal function to make the negative pressure fan 42 run in reverse. Through the reverse rotation of the fan, the dust particles attached to the filter 43 can be removed, thereby restoring the normal air permeability and dust removal efficiency of the filter 43. When the cleaning work is completed, the system will monitor that the pressure has returned to the set normal value. When the pressure of the filter 43 drops to a certain limit, the pressure controller 41 will control the negative pressure fan 42 to resume forward rotation again and resume normal negative pressure exhaust operation. The whole process is precisely regulated by the pressure controller 41 to ensure that the dust collector maintains an efficient and stable working state during operation, and effectively avoids the reduction of dust removal efficiency due to dust accumulation.

[0066] The present invention also discloses a dust removal method of a filter cartridge dust collector with a synergistic dust cleaning function, which adopts the filter cartridge dust collector with a synergistic dust cleaning function and specifically comprises the following steps:

[0067] When the dust collector is performing adsorption dust removal, the induced draft fan connected to the air inlet 52 draws the dust-laden air flow into the air inlet 52 of the dust collector case 5 and moves toward the vibration-assisted dust-cleaning filter cartridge 2; the dust-laden air flow will first contact the annular dust collecting baffle 3, and some dust particles will be captured and adsorbed by the annular pleated filter screen 33; the remaining dust particles that cannot be captured by the annular pleated filter screen 33 will move between the intervals of each annular dust collecting baffle 3 to the filter material surface of the vibration-assisted dust-cleaning filter cartridge 2, and then further adsorb and remove the dust particles in the dust-laden gas. The double dust removal of the annular dust collecting baffle 3 and the vibration-assisted dust-cleaning filter cartridge 2 not only effectively improves the dust removal effect and ensures the cleanliness of the exhaust gas, but also effectively reduces the dust removal pressure of the filter cartridge 26, reduces the dust accumulation speed on the surface of the filter cartridge 26, reduces the frequency of cleaning inside the dust collector, and realizes long-term and efficient dust removal operations.

[0068] When cleaning the inside of the dust collector, a high-speed jet airflow enters the induced boost pulse jet device 1 from the air supply pipe 11, and the high-speed jet airflow first enters the cavity formed by the upper cover 13, the first-level reducer 14 and the nozzle support 15, and the negative pressure generated forms a first-level induced airflow boost; the jet airflow increases the jet flow rate through the induced airflow, and then accelerates the airflow through the first-level reducer 14; the jet airflow that completes the first-level boost acceleration flows from the first-level reducer 14 into the second-level reducer 17, and the flow of high-speed airflow also generates negative pressure in the cavity of the second-level reducer 17, prompting the external airflow to enter the second-level reducer 17 through the second annular seam air inlet 110 on the second-level reducer 17, and then the second-level induced airflow merges with the first-level induced airflow to complete the secondary boost acceleration of the jet airflow, and finally sprays from the second-level reducer 17 to the vibration-assisted cleaning filter cartridge 2. The high-speed jet airflow is guided by the guide body 22 and sprayed toward the vibration plate 25. Under the impact of the jet airflow, the vibration plate 25 beats the arc ring 24 downward to generate vibration and transmits it to the hollow circular tube 21, and then drives the filter cartridge 26 to vibrate through the hollow circular tube 21, shaking off and removing the dust particles attached to the outer surface of the filter cartridge 26.

[0069] At the same time, the blowing channel 31 in the annular dust collecting baffle 3 also simultaneously passes the blowing airflow into the supporting column 34, and the blowing airflow enters the dust collecting cavity formed by the inclined groove baffle 32 and the annular pleated filter 33 through the blowing hole 35, thereby completing the cleaning of the dust particles attached to the annular pleated filter 33.

[0070] A part of the dust particles sprayed down from the filter cartridge 26 and the annular pleated filter screen 33 will fall on the inclined groove baffle 32 and slide into the atomizing device 6 by gravity and be discharged in the form of muddy water; another part of the dust particles that cannot be captured by the atomizing device 6 will sink rapidly under the action of the negative pressure device 4, most of the dust particles will mix with the muddy water at the bottom of the dust collector housing 5, and other small parts of the dust particles will be captured by the filter screen 43 of the negative pressure device 4. The muddy water gathered at the bottom of the dust collector housing 5 is discharged and regulated by the drainage device 7.

[0071] In addition, when the dust collector is performing adsorption dust removal, the negative pressure device 4 can also perform backblowing in time to clean the dust particles attached to the filter 43; the induced draft fan connected to the air inlet 52 only operates in the adsorption dust removal stage, and the negative pressure device 4 only operates to extract airflow and backblow to clean the circular filter 43 in the cleaning stage.

[0072] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
