Description

Technical Field

[0001] This utility model relates to the field of industrial dust removal equipment technology, and in particular to an electrostatic precipitator-to-bag dust collector. Background Technology

[0002] Electrostatic precipitator-to-baghouse dust collectors are high-efficiency purification devices that transform traditional electrostatic precipitators into hybrid electrostatic-baghouse dust collectors or pure baghouse dust collectors. They are widely used in flue gas dust removal in industries such as power, steel, and cement. Through the synergistic effect of electric field pre-charging and filter bag filtration, the concentration of particulate matter in flue gas can be reduced to below 10mg / m³, meeting stringent environmental emission requirements.

[0003] The existing technology has the following problems: Dust collected during the dust removal process tends to accumulate and clump on the inner wall of the ash hopper, especially in flue gas environments with high humidity. This can easily cause ash buildup and blockage of the ash hopper, requiring frequent shutdowns for manual cleaning, which leads to decreased equipment operating efficiency and a significant increase in maintenance costs. Utility Model Content

[0004] The main purpose of this utility model is to provide an electrostatic precipitator converted into a bag filter, which can effectively solve the problem of dust accumulation and blockage in the ash hopper affecting operation.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An electrostatic precipitator-to-bag filter includes a support frame, a main body of the device is arranged inside the support frame, an air bag is arranged outside the main body of the device, a dust hopper is arranged at the bottom of the main body of the device, a dust discharge component is arranged at the bottom of the dust hopper, an air inlet is arranged outside the main body of the device, an exhaust outlet is arranged outside the main body of the device, an anti-accumulation mechanism is arranged outside the support frame, and a monitoring mechanism is arranged outside the main body of the device. The anti-accumulation mechanism includes a housing, the outer side of which is fixedly connected to the outer side of a support frame. A motor is installed inside the housing, and a turntable is fixedly connected to the output end of the motor. An eccentric shaft is fixedly connected to the outer edge of the turntable. A hollow frame is slidably connected to the outer periphery of the eccentric shaft. A toothed block is fixedly connected to one end of the hollow frame. A support rod is fixedly connected inside the housing, and a rack is slidably connected to the outer periphery of the support rod. A rubber block is fixedly connected to the top of the rack. The monitoring mechanism includes two pressure sensors and a housing. The two pressure sensors are fixedly connected inside the air inlet and the air outlet, respectively. The outer side of the housing is fixedly connected to the outer side of the main body of the device. A second motor is installed inside the housing. A protrusion is fixedly connected to the output end of the second motor. A guide rod is fixedly connected inside the housing. A spring is sleeved on the outer periphery of the guide rod. A connecting rod is slidably connected to the outer periphery of the guide rod. A connecting block is fixedly connected to the outer side of the connecting rod. An electrode plate is fixedly connected to the top of the connecting rod. An electrode plate is installed inside the housing. A warning light is fixedly connected to the top of the housing.

[0006] Preferably, the hollow frame is rotatably connected to the inside of the outer shell, and the toothed block and the toothed rack mesh with each other.

[0007] Preferably, the outer side of the rack is slidably connected to the inside of the outer casing, and the rubber block and the ash hopper abut against each other.

[0008] Preferably, a controller is disposed inside the housing, and a battery is disposed inside the housing.

[0009] Preferably, one end of the spring is fixedly connected inside the housing, and the other end of the spring is fixedly connected to the outside of the connecting rod.

[0011] Preferably, the outer side of the connecting rod is slidably connected to the inside of the housing.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model provides an electrostatic precipitator modified into a bag filter. The anti-accumulation mechanism is driven by a motor to rotate a turntable. The turntable drives a hollow frame to swing through an eccentric shaft. The hollow frame drives a toothed block to reciprocate and mesh with a rack. The rack drives a rubber block to strike the ash hopper at high frequency, which can quickly disperse agglomerated dust and prevent dust from accumulating and agglomerating on the inner wall of the ash hopper, thus avoiding the need for frequent shutdowns for manual cleaning, reduced equipment operating efficiency, and significantly increased maintenance costs.

[0013] 2. This utility model provides an electrostatic precipitator for bag filters. The monitoring mechanism collects the pressure difference between the inlet and outlet in real time through a pressure sensor. When the difference exceeds a threshold, the controller starts motor 2 to drive the protrusion to rotate. The protrusion pushes the connecting block to drive the connecting rod to slide down along the guide rod. When the connecting rod compresses the spring, the spring pushes the connecting rod when the protrusion disengages from the connecting block. The connecting rod drives electrode 1 and electrode 2 to contact each other, and the warning light flashes to provide an immediate alarm. This enables early warning of filter bag blockage, damage and other faults, avoids excessive emissions, and significantly enhances environmental compliance. Attached Figure Description

Detailed Implementation

[0016] 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.

[0017] like Figure 1-6 As shown, an electrostatic precipitator converted to a bag filter includes a support frame 1, a device body 2 inside the support frame 1, an air tank 3 outside the device body 2, a dust hopper 4 at the bottom of the device body 2, a dust discharge assembly 5 at the bottom of the dust hopper 4, an air inlet 6 outside the device body 2, an exhaust outlet 7 outside the device body 2, an anti-accumulation mechanism 8 outside the support frame 1, and a monitoring mechanism 9 outside the device body 2. The anti-stacking mechanism 8 includes a housing 80, which is fixedly connected to the outside of the support frame 1. A motor 81 is installed inside the housing 80. A turntable 82 is fixedly connected to the output end of the motor 81. An eccentric shaft 83 is fixedly connected to the outer edge of the turntable 82. A hollow frame 84 is slidably connected to the outer periphery of the eccentric shaft 83. A toothed block 85 is fixedly connected to one end of the hollow frame 84. A support rod 86 is fixedly connected inside the housing 80. A rack 87 is slidably connected to the outer periphery of the support rod 86. A rubber block 88 is fixedly connected to the top of the rack 87. It should be noted that the main body 2 of the device is equipped with a filter bag assembly and an electric field pre-charge device. The air tank 3 provides a pulse cleaning air source. The anti-accumulation mechanism 8 drives the turntable 82 to rotate through the motor 81. The turntable 82 drives the hollow frame 84 to swing through the eccentric shaft 83. The hollow frame 84 drives the toothed block 85 to reciprocate to mesh with the rack 87. The rack 87 drives the rubber block 88 to strike the ash hopper 4 at high frequency, which can quickly disperse the agglomerated dust.

[0018] The monitoring mechanism 9 includes two pressure sensors 90 and a housing 91. The two pressure sensors 90 are fixedly connected inside the air inlet 6 and the exhaust port 7, respectively. The housing 91 is fixedly connected to the outside of the main body 2. A second motor 92 is installed inside the housing 91. A protrusion 93 is fixedly connected to the output end of the second motor 92. A guide rod 94 is fixedly connected inside the housing 91. A spring 95 is sleeved on the outer periphery of the guide rod 94. A connecting rod 96 is slidably connected to the outer periphery of the guide rod 94. A connecting block 97 is fixedly connected to the outer side of the connecting rod 96. An electrode plate 98 is fixedly connected to the top of the connecting rod 96. An electrode plate 99 is installed inside the housing 91. A warning light 910 is fixedly connected to the top of the housing 91.

[0019] It should be noted that the pressure sensor 90 collects the pressure difference between the inlet and outlet in real time. When the difference exceeds the threshold, the controller 911 starts the motor 92 to drive the protrusion 93 to rotate. The protrusion 93 pushes the connecting block 97 to drive the connecting rod 96 to slide down along the guide rod 94. The connecting rod 96 compresses the spring 95. When the protrusion 93 disengages from the connecting block 97, the spring 95 pushes the connecting rod 96. The connecting rod 96 drives the electrode plate 98 and the electrode plate 99 to contact. The warning light 910 flashes to immediately alarm and prompt the staff to check whether the filter bag is blocked, damaged or otherwise faulty.

[0020] like Figure 4 As shown, the hollow frame 84 is rotatably connected to the inside of the outer shell 80, and the toothed block 85 and the rack 87 mesh with each other.

[0021] It should be noted that the rotating connection of the hollow frame 84 ensures that the hollow frame 84 can swing back and forth, and the meshing between the toothed block 85 and the rack 87 enables the toothed block 85 to drive the rack 87 to move.

[0022] like Figure 2 , Figure 4 As shown, the outer side of the rack 87 is slidably connected to the inside of the outer casing 80, and the rubber block 88 abuts against the ash hopper 4.

[0023] It should be noted that the outer casing 80 provides a sliding guide for the rack 87, and the rubber block 88 abuts against the ash hopper 4, so that the rubber block 88 can knock the ash hopper 4 to shake off the dust.

[0024] like Figure 6As shown, a controller 911 and a battery 912 are installed inside the housing 91.

[0025] It should be noted that the controller 911 has a preset pressure difference threshold. When the detected value exceeds the threshold, the second motor 92 will be automatically started, and the battery 912 can provide power to the second motor 92.

[0026] like Figure 6 As shown, one end of the spring 95 is fixedly connected to the inside of the housing 91, and the other end of the spring 95 is fixedly connected to the outside of the connecting rod 96.

[0027] It should be noted that the spring 95 can be compressed by the connecting rod 96 to generate elastic force. When the protrusion 93 disengages from the connecting block 97, the spring 95 pushes the connecting rod 96 to cause the electrode plate 1 98 and the electrode plate 2 99 to contact each other, making the warning light 910 light up. Then, the connecting rod 96 is pulled to reset, the electrode plate 1 98 and the electrode plate 2 99 separate, the warning light 910 goes out, and the warning light 910 flashes continuously.

[0028] like Figure 6 As shown, protrusion 93 and connecting block 97 abut against each other, and electrode plate 1 98 and electrode plate 2 99 abut against each other.

[0029] It should be noted that the protrusion 93 and the connecting block 97 abut against each other, so that the protrusion 93 can push the connecting block 97, and the electrode plate 1 98 and the electrode plate 2 99 abut against each other, so that the warning light 910 can light up.

[0030] like Figure 6 As shown, the outer side of the connecting rod 96 is slidably connected to the inside of the housing 91.

[0031] It should be noted that the housing 91 can provide additional guidance for the connecting rod 96, enabling the connecting rod 96 to move stably.

[0032] Working principle: Dust-laden flue gas enters the main body 2 of the device through the inlet 6. After being pre-charged by the electric field, the particulate matter is intercepted by the filter bag. The purified flue gas is discharged from the exhaust port 7. The collected dust falls into the ash hopper 4. The ash discharge component 5 continuously discharges the dust. The anti-accumulation mechanism 8 is activated simultaneously. The motor 81 drives the turntable 82 to rotate. The turntable 82 drives the hollow frame 84 to swing through the eccentric shaft 83. The hollow frame 84 drives the toothed block 85 to reciprocate and mesh with the rack 87. The rack 87 drives the rubber block 88 to strike the ash hopper 4 at high frequency, quickly breaking up the agglomerated dust. Pressure sensor 9... 0. Real-time monitoring of the pressure difference between the inlet and outlet. When the difference exceeds the threshold, the controller 911 starts the motor 2 92 to drive the protrusion 93 to rotate. The protrusion 93 pushes the connecting block 97 to drive the connecting rod 96 to slide down along the guide rod 94. The connecting rod 96 compresses the spring 95. When the protrusion 93 disengages from the connecting block 97, the spring 95 pushes the connecting rod 96. The connecting rod 96 drives the electrode plate 1 98 and the electrode plate 2 99 to contact. The warning light 910 flashes to immediately alarm and prompt the staff to check whether the filter bag is blocked, damaged or otherwise faulty.
