Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, specifically to a pulse-jet bag filter. Background Technology

[0002] Baghouse dust collectors efficiently filter particulate matter in flue gas through filter bags, purifying the emitted gas. They are widely used in flue gas systems in industries such as power and metallurgy to treat high-temperature and corrosive gases, meet environmental emission standards, and ensure air quality.

[0003] In existing flue gas treatment systems, bag filters use centralized exhaust for backflushing, resulting in limited air pressure allocated to each group of bags. This limits the backflushing cleaning intensity, affecting the cleaning effect and long-term filtration reliability. Therefore, a pulse-jet bag filter is proposed. Utility Model Content

[0004] To address the problems in existing technologies, this utility model provides a pulse-jet baghouse dust collector, which offers a dust removal mechanism with good reverse-blowing cleaning effect for smoke exhaust systems. Through the cleaning component, the high-pressure air generated by the pulse mechanism is individually discharged above the opening of each group of bags in the baghouse dust collector, allowing the high-pressure air to blow dust from the exhaust of each group of bags individually. This enables the dust particles adhering to the outside of the bags to be better cleaned by reverse-blowing, ensuring the reliability of the bags for long-term use.

[0005] The technical solution adopted by this utility model to solve its technical problem is a pulse bag dust collector, including a bag dust collector, a pulse mechanism and a dust removal component. The pulse mechanism is located at the bottom of one end of the bag dust collector, and the dust removal component is located at the top inside the bag dust collector.

[0006] The dust removal assembly includes an XZ axis moving assembly, a cover plate, and a nozzle. The cover plate is disposed on the XZ axis moving assembly, and the nozzle is connected to the bottom of the cover plate. The air inlet end of the nozzle is provided with an air inlet connector, and the air inlet connector is disposed on the top of the cover plate.

[0007] By adopting the above technical solution, a dust removal mechanism with good reverse-blowing cleaning effect is provided for the smoke exhaust system through the components consisting of bag dust collector, pulse mechanism and dust removal component. The dust removal component discharges high-pressure air generated by pulse mechanism to each group of bags in the bag dust collector individually, so that the high-pressure air blows dust into each group of bags. This allows the dust particles adhering to the outside of the bags to be better cleaned by reverse-blowing, ensuring the reliability of the bags for long-term use.

[0008] Specifically, the XZ axis moving assembly includes a Z-axis lead screw and an X-axis lead screw. Two sets of Z-axis lead screws are provided and are rotatably connected to the top two ends of the bag filter housing via bearings. A Z-axis threaded sleeve is threaded onto the Z-axis lead screw. A guide rail is provided inside the bag filter and at the bottom of the Z-axis lead screw. A slider is slidably connected to the guide rail, and the top of the slider is connected to the Z-axis threaded sleeve.

[0009] The bottom of the slider is connected to a mounting base, and the two ends of the X-axis lead screw are respectively rotatably connected to the mounting base at the corresponding position through bearings. A first servo motor is mounted on the back of the mounting base below one set of Z-axis lead screws, and the drive end of the first servo motor is connected to the rotation shaft at one end of the X-axis lead screw.

[0010] Specifically, an X-axis threaded sleeve is threaded onto the X-axis lead screw, the cover plate is installed at the bottom of the X-axis threaded sleeve, a guide rod is provided on one side of the X-axis lead screw, the two ends of the guide rod are connected to the mounting base at the corresponding positions, and one end of the X-axis threaded sleeve is sleeved on the guide rod.

[0011] By adopting the above technical solution, through the setting of the X-axis lead screw and the X-axis sleeve, the first servo motor drives the X-axis lead screw, which in turn drives the X-axis sleeve to move in the X-axis direction above the bag opening in the bag dust collector, so that the nozzles under the cover plate can move one by one to the top of the bag opening in the X-axis direction.

[0012] Specifically, a second servo motor is installed on the top of the outer side of the bag filter. The drive end of the second servo motor and the rotating shaft ends of the two sets of Z-axis lead screws are all equipped with synchronous pulleys. The synchronous pulleys are connected to each other by a synchronous belt. A support wheel is rotatably connected to the bag filter on the top side of the second servo motor through a bearing. The bottom of the synchronous pulley rests on the top of the support wheel.

[0013] By adopting the above technical solution, through the setting of synchronous pulleys and synchronous belts, after the corresponding synchronous pulleys are driven by the second servo motor, the two sets of Z-axis lead screws are rotated based on the synchronization of the synchronous belt. This causes the mounting base to move in the Z-axis direction within the bag filter based on the guide rail, enabling the nozzle to move in the Z-axis direction and work above the bag opening in the Z-axis direction.

[0014] Specifically, a pipe joint is provided at the top of one end of the housing of the bag filter. The pulse mechanism includes an air compressor and a pressure tank. The exhaust end of the air compressor is connected to the inlet end of the pressure tank. The exhaust end of the pressure tank is connected to the pipe joint through a pipe. Solenoid valves are installed on both the inlet and exhaust ends of the pressure tank.

[0015] The pipe joint and the air inlet joint are connected by a flexible hose.

[0016] By adopting the above technical solution, the air discharged from the air compressor is stored in the pressure tank of the pulse mechanism. When pulse cleaning of the filter bag is required, the solenoid valve at the exhaust end of the pressure tank is opened, allowing high-pressure air to enter the nozzle through the pipe joint and the air inlet joint. The nozzle discharges the high-pressure air into the filter bag below, so that the filter bag receives high-pressure back-blowing cleaning treatment.

[0017] The beneficial effects of this utility model are as follows: The assembly consisting of a bag filter, a pulse mechanism, and a cleaning component provides a dust removal mechanism with good back-blowing cleaning effect for the flue gas system. The cleaning component delivers high-pressure air generated by the pulse mechanism individually to the top of each group of bags in the bag filter, allowing the high-pressure air to blow dust from each group of bags separately. This ensures that the dust particles adhering to the outside of the bags are better cleaned by back-blowing, guaranteeing the long-term reliability of the bags. This solves the problem in existing flue gas treatment systems where bag filters, due to centralized exhaust back-blowing, have limited air pressure allocated to each group of bags, resulting in limited back-blowing cleaning intensity and affecting the cleaning effect and long-term filtration reliability.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1-4 As shown, the present invention provides a pulse-jet bag filter, which includes a bag filter 1, a pulse mechanism 2, and a cleaning assembly 3. The pulse mechanism 2 is located at the bottom of one end of the bag filter 1, and the cleaning assembly 3 is located at the top inner part of the bag filter 1.

[0026] The dust removal assembly 3 includes an XZ axis moving assembly, a cover plate 310, and a nozzle 311. The cover plate 310 is disposed on the XZ axis moving assembly, and the nozzle 311 is connected to the bottom of the cover plate 310. The air inlet end of the nozzle 311 is provided with an air inlet connector 312, and the air inlet connector 312 is disposed on the top of the cover plate 310.

[0027] This utility model also includes the XZ axis moving assembly comprising a Z-axis lead screw 31 and an X-axis lead screw 36. Two sets of Z-axis lead screws 31 are provided and are respectively rotatably connected to the top two ends of the housing of the bag dust collector 1 through bearings. A Z-axis sleeve 32 is threaded on the Z-axis lead screw 31. A guide rail 33 is provided inside the bag dust collector 1 and located at the bottom of the Z-axis lead screw 31. A slider 34 is slidably connected on the guide rail 33. The top of the slider 34 is connected to the Z-axis sleeve 32.

[0028] The bottom of the slider 34 is connected to a mounting base 35. The two ends of the X-axis lead screw 36 are respectively rotatably connected to the mounting base 35 at the corresponding positions through bearings. A first servo motor 39 is mounted on the back of the mounting base 35 below a set of Z-axis lead screws 31. The drive end of the first servo motor 39 is connected to the rotation shaft at one end of the X-axis lead screw 36.

[0029] The present invention also includes an X-axis threaded sleeve 38 threaded on the X-axis lead screw 36, a cover plate 310 installed at the bottom of the X-axis threaded sleeve 38, a guide rod 37 provided on one side of the X-axis lead screw 36, the two ends of the guide rod 37 being connected to the mounting base 35 at the corresponding positions, and one end of the X-axis threaded sleeve 38 being sleeved on the guide rod 37.

[0030] In use, by using the X-axis lead screw 36 and X-axis sleeve 38, the first servo motor 39 drives the X-axis lead screw 36, which in turn drives the X-axis sleeve 38 to move in the X-axis direction above the bag opening in the bag dust collector 1, so that the nozzles 311 below the cover plate 310 can move one by one to the top of the bag opening in the X-axis direction.

[0031] This utility model also includes a second servo motor 313 installed on the top of the outer side of the bag dust collector 1. The drive end of the second servo motor 313 and the rotating shaft ends of the two sets of Z-axis lead screws 31 are all equipped with synchronous pulleys 314. The synchronous pulleys 314 are connected to each other by a synchronous belt 316. A support wheel 315 is rotatably connected to the bag dust collector 1 on the top side of the second servo motor 313 by a bearing. The bottom of the synchronous pulley 314 rests on the top of the support wheel 315.

[0032] In use, based on the synchronous pulley 314 and synchronous belt 316, the corresponding synchronous pulley 314 is driven by the second servo motor 313. Based on the synchronization of the synchronous belt 316, the two sets of Z-axis lead screws 31 are rotated, which causes the mounting base 35 to move in the Z-axis direction within the bag filter 1 based on the guide rail 33. This allows the nozzle 311 to move in the Z-axis direction and work above the bag opening in the Z-axis direction.

[0033] The present invention also includes that a pipe joint 11 is provided at the top of one end of the housing of the bag dust collector 1, the pulse mechanism 2 includes an air compressor and a pressure tank, the exhaust end of the air compressor is connected to the inlet end of the pressure tank, the exhaust end of the pressure tank is connected to the pipe joint 11 through a pipe, and a solenoid valve is installed on both the inlet end and the exhaust end of the pressure tank.

[0034] The pipe joint 11 and the air inlet joint 312 are connected by a flexible hose.

[0035] In use, the pulse mechanism 2 stores the air discharged from the air compressor through the pressure tank in the pulse mechanism 2. When pulse cleaning of the filter bag is required, the solenoid valve at the exhaust end of the pressure tank is opened, allowing high-pressure air to enter the nozzle 311 through the pipe joint 11 and the air inlet joint 312. The nozzle 311 discharges the high-pressure air into the filter bag below, so that the filter bag receives high-pressure back-blowing cleaning treatment.

[0036] In use, the exhaust end of the flue gas treatment system is connected to the bottom of one end of the bag filter 1. The filter bag in the bag filter 1 isolates the flue gas from the top of the bag filter 1. The exhaust end of the bag filter 1 is then connected to the chimney behind it. The power supply components in the work site provide power to the electrical mechanism in this application.

[0037] During operation, the incoming flue gas is filtered through the filter bags in the baghouse dust collector 1, and relatively clean air is discharged from the top of the baghouse dust collector 1. After long-term use, personnel can use the pulse mechanism 2 to supply high-pressure air to the dust removal assembly 3 to back-flush and clean the filter bags in the baghouse dust collector 1 one by one. The pressure tank in the pulse mechanism 2 stores the air discharged from the air compressor. When pulse cleaning of the filter bags is required, the solenoid valve at the exhaust end of the pressure tank opens, allowing high-pressure air to enter the nozzle 311 through the pipe joint 11 and the air inlet joint 312. The nozzle 311 discharges the high-pressure air into the filter bags below, so that the filter bags receive high-pressure back-flushing cleaning treatment. During the back-flushing cleaning, the corresponding synchronous pulley 3 is driven by the second servo motor 313. After step 14, based on the synchronization of the synchronous belt 316, the two sets of Z-axis lead screws 31 are rotated, and the mounting base 35, guided by the guide rail 33, drives the X-axis lead screw 36 to move in the Z-axis direction within the bag filter 1, enabling the nozzles 311 to move in the Z-axis direction and work above the bag opening in the Z-axis direction. The first servo motor 39 drives the X-axis lead screw 36, which in turn drives the X-axis sleeve 38 to move in the X-axis direction above the bag opening in the bag filter 1. This allows the nozzles 311 below the cover plate 310 to move one by one to the top of the bag opening in the X-axis direction, realizing independent backflushing cleaning of the top of each set of bags. This improves the backflushing cleaning and maintenance effect of each set of bags and ensures the reliability of the long-term filtration use of the bags.
