Description

Technical Field

[0001] This utility model relates to the field of air pollution control technology, and in particular to a dust removal device for air pollution control. Background Technology

[0002] Baghouse dust collectors, due to their high efficiency, strong adaptability, and stable operation, have become one of the most widely used devices in the field of industrial flue gas treatment, serving industries such as power, metallurgy, and building materials. Their core working principle lies in the fact that when dust-laden airflow passes through filter bags (dust filter bags) made of filter cloth, dust is captured on the outer surface of the filter bags, while the purified air passes through the filter bags into the clean air chamber (located above the shelf where the filter bags are installed), and is finally discharged by an induced draft fan.

[0003] However, as a core consumable and vulnerable component of dust collection equipment, the filter bag's operating status (whether it is damaged, detached, clogged, or whether cleaning is thorough) directly affects the equipment's dust collection efficiency, operational stability, and emission compliance. In traditional baghouse dust collector structures, monitoring the filter bag's operating status presents significant challenges and limitations: High monitoring lag and significant risks: The working status of the filter bags is completely enclosed inside the equipment, making it impossible for operators to observe them in real time and visually. Under normal operating conditions, unless the equipment stops for other reasons or an alarm is triggered by an abnormal decrease in processing efficiency, it is difficult to proactively detect early problems (such as tiny holes or slight clogging in a single filter bag). Bag ruptures can lead to excessive emissions that cannot be detected in time, posing serious environmental compliance risks; while bag clogging can cause a sharp increase in filtration resistance, significantly increasing the power consumption of the induced draft fan. If not addressed in time, it may worsen into excessive equipment resistance, forcing a shutdown.

[0004] The inspection process is cumbersome and maintenance costs are high: Regular manual inspections or fault confirmation of filter bags require the equipment to be stopped first (shutdown). This necessitates significant time and manpower to open the sealed doors or manholes of the chamber (opening the chamber). This process involves complex preparatory work to ensure safety (such as cooling, depressurization, and prevention of harmful gas leaks), and maintenance personnel must enter the dusty, dark, and confined space to inspect each bag individually. This is high-risk, inefficient, and labor-intensive, and the chamber must be resealed after inspection. The entire process results in long unplanned downtime, causing significant production losses and high maintenance resource investment. Therefore, a dust removal device for atmospheric pollution control is proposed to address these problems. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0006] Therefore, one objective of this utility model is to provide a dust removal device for air pollution control, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0007] To achieve the above objectives, one embodiment of the present invention provides a dust removal device for air pollution control, comprising a support, a chamber, a funnel, and a manual valve. The top of the support is fixedly connected to the chamber, the bottom of the chamber is fixedly connected to the funnel, and the bottom of the funnel is fixedly connected to the manual valve. An input pipe is fixedly connected to the side of the chamber, and a shelf is fixedly connected to the inside of the chamber. Several positioning holes are opened on the shelf, and a dust filter bag is fixedly connected to each positioning hole. An exhaust fan is fixedly connected to the outside of the silo body, and the exhaust fan is connected to the top of the middle layer plate of the silo body; A main pipe is fixedly connected to the side of the hopper, and several secondary pipes are fixedly connected to one side of the main pipe. A high-pressure spray pipe is fixedly connected to the bottom of the secondary pipe, and a dust filter bag cylinder is correspondingly located below each of the high-pressure spray pipes. A viewing window is fixedly connected to the side of the silo body. The viewing window includes a frame and tempered glass inside the frame. A lamp is fixedly connected to the silo wall of the silo body. The illumination lamp is directed toward the shelf. A soft cover is fixedly connected to the wall of the compartment. A lens tube is fixedly connected to the center of the soft cover. The top of the lens tube has an eyepiece, and the other end of the lens tube is located above the shelf.

[0008] Preferably, in any of the above embodiments, the support is welded to the hopper body, and the diameter of the funnel gradually decreases from top to bottom.

[0009] The above technical solution is adopted: This device is specially used for air pollution control. Its basic working principle is as follows: When the induced draft fan is working, air enters the chamber through the input pipe. The air can only enter the shelf above the filter bag after passing through the dust filter bag cylinder. Finally, the purified air is output from the air outlet of the induced draft fan. Impurities and particles remain on the outside of the dust filter bag cylinder. When too many impurities accumulate, high-pressure air is introduced into the main and auxiliary pipes. The high-pressure airflow is output to the corresponding dust filter bag cylinder through the high-pressure nozzle. The dust filter bag cylinder shakes, and the dust particles on its surface fall into the funnel. The funnel can be drained by opening the manual valve.

[0010] Preferably, in any of the above embodiments, the shelf is located on the upper part of the inner side of the compartment, and the positioning holes are arranged in a linear array of multiple sets on the shelf.

[0011] Using the above technical solution: In the past, to check the condition of the dust filter bags inside the device, such as whether they were damaged, detached, clogged, or had poor dust removal performance, it was necessary to stop the machine and disassemble it.

[0012] This device features a pressure-resistant and high-temperature-resistant square viewing window installed on the side wall of the clean air chamber (i.e., the area above the shelves), with a light source nearby to ensure sufficient illumination for observation. Simultaneously, a movable lens is incorporated, sealed with a rubber cover. Using the lens in conjunction with visual inspection, staff can quickly and directly observe and check the working status of the filter bags inside the chamber, inspecting for damage, detachment, or clogging without stopping the machine or opening the chamber. Any abnormalities (such as bag rupture leading to excessive emissions) can be addressed immediately, reducing equipment damage and emission risks, and effectively solving the problems existing in current technologies.

[0013] Preferably, in any of the above embodiments, the dust filter bag is connected to the shelf via a flange, and the material of the dust filter bag is polyester fiber.

[0014] Preferably, in any of the above embodiments, the induced draft fan includes a body, a motor, and a turbine, wherein the output end of the motor is connected to the turbine, the motor is mounted on the side of the body, and the turbine is movably connected inside the body.

[0015] The above technical solution is adopted: The device structure consists of: Support structure: The support is a welded steel structure, and its top is fixedly connected to the silo body to provide stable support.

[0016] Main body and dust collection unit: A funnel is fixedly connected to the bottom of the silo body. The diameter of the funnel gradually decreases from top to bottom. A manual valve is fixedly connected to the bottom of the funnel to control dust discharge.

[0017] Filtration Unit: A fixedly connected shelf is located on the upper middle part of the inner side of the chamber. Multiple sets of positioning holes are linearly arrayed on the shelf. Each positioning hole is fixedly connected to a filter bag (made of industrial filter cloth) through a flange seal.

[0018] Airflow system: An input pipe (dust-laden gas inlet) is fixedly connected to the side of the chamber. An induced draft fan is fixedly connected to the outside of the chamber, consisting of a body, a motor, and a turbine (the motor output is connected to the turbine). The induced draft fan connects to the space above the middle shelf of the chamber (i.e., the clean air chamber) and is responsible for drawing in purified air.

[0019] Dust removal system: A main pipe (high-pressure air inlet) is fixedly connected to the side of the silo. Several secondary pipes are fixedly connected to one side of the main pipe. A high-pressure nozzle is fixedly connected to the bottom of each secondary pipe. The high-pressure nozzles are positioned directly above the filter bag cylinders, one-to-one.

[0020] Visual monitoring system: A viewing window is fixedly connected to the clean air chamber wall on the side of the silo. The viewing window consists of a metal frame and pressure-resistant, high-temperature-resistant tempered glass inside the frame. A spotlight is fixedly connected to the silo wall above (or near) the viewing window. The spotlight is explosion-proof, and its illumination direction is towards the dust filter bags on the shelf, providing a light source for observation.

[0021] A soft cover is fixedly connected to the warehouse wall below (or near) the viewing window. The soft cover is made of oil-resistant and high-temperature resistant rubber.

[0022] The lens tube is fixedly connected to the center of the soft cover. The top of the lens tube has an eyepiece for observation, and the other end of the lens tube extends to the area above the shelf.

[0023] Preferably, in any of the above embodiments, the viewing window is located below the lamp, and the lamp, viewing window, and soft cover are located above the shelf. The lamp is explosion-proof, and the soft cover is made of rubber.

[0024] This device innovatively achieves real-time, intuitive, and non-contact in-situ observation of the working status of dust collector bags by integrating a viewing window, lighting, and a lens tube with a movable sealing structure (soft cover) into the clean air chamber (the space above the shelf). Operators can quickly determine whether the dust collector bag cylinders are damaged, detached, clogged, or incompletely cleaned without stopping the machine or opening the chamber, and can respond immediately (such as marking damaged bags for later replacement). This greatly improves equipment maintenance efficiency, reduces unplanned downtime, and lowers the risk of emissions exceeding standards and further equipment damage due to the failure to detect bag abnormalities in a timely manner.

[0025] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: This dust removal device for air pollution control features a pressure-resistant and high-temperature-resistant square viewing window installed on the side wall of the clean air chamber (above the shelves). A light is installed near the viewing window to ensure sufficient illumination for observation. Simultaneously, a movable lens is installed, sealed with a rubber cover. Using the lens in conjunction with visual inspection, workers can quickly and directly observe and check the working status of the filter bags inside the chamber, looking for damage, detachment, or clogging. This eliminates the need to stop the machine and open the chamber. Any abnormalities (such as bag rupture leading to excessive emissions) can be addressed immediately, reducing equipment damage and emission risks, and effectively solving problems existing in current technologies.

[0033] Example 2: This device is specifically designed for air pollution control. Its basic working principle is as follows: When the induced draft fan 9 is working, air enters the chamber 2 through the input pipe 5. The air passes through the dust filter bag cylinder 8 before entering the shelf 6. Finally, the purified air is output from the outlet of the induced draft fan 9. Impurities and particles remain on the outside of the dust filter bag cylinder 8. When too many impurities accumulate, high-pressure air is introduced into the main pipe 10 and the secondary pipe 11. The high-pressure airflow is output through the high-pressure nozzle 12 to the corresponding dust filter bag cylinder 8. The dust filter bag cylinder 8 shakes, and the dust particles on its surface fall into the funnel 3. The funnel 3 can be drained by opening the manual valve 4.

[0034] Device structure composition: Support structure: The support frame 1 is a welded steel structure, and its top is fixedly connected to the chamber body 2 to provide stable support.

[0035] Main body and dust collection unit: A funnel 3 is fixedly connected to the bottom of the silo 2. The diameter of the funnel 3 gradually decreases from top to bottom. A manual valve 4 is fixedly connected to its bottom end to control dust discharge.

[0036] Filter unit: A shelf 6 is fixedly connected to the upper middle part of the inner side of the chamber 2. Multiple sets of positioning holes 7 are linearly arrayed on the shelf 6. A filter bag cylinder 8 (made of industrial filter cloth) is fixedly connected to each positioning hole 7 through a flange seal.

[0037] Airflow system: An input pipe 5 (dust-containing gas inlet) is fixedly connected to the side of the chamber 2. An exhaust fan 9 is fixedly connected to the outside of the chamber 2. The exhaust fan 9 includes a body, a motor, and a turbine (the motor output is connected to the turbine). The exhaust fan 9 connects to the space above the middle layer plate 6 of the chamber 2 (i.e., the clean air chamber) and is responsible for drawing in purified air.

[0038] Dust removal system: A main pipe 10 (high-pressure air source inlet) is fixedly connected to the side of the silo body 2. Several secondary pipes 11 are fixedly connected to one side of the main pipe 10. A high-pressure nozzle 12 is fixedly connected to the bottom of each secondary pipe 11. The high-pressure nozzles 12 are positioned directly above the dust filter bag cylinders 8, corresponding one-to-one.

[0039] Visual monitoring system: A viewing window 13 is fixedly connected to the clean air chamber wall on the side of the chamber 2. The viewing window 13 includes a metal frame and pressure-resistant, high-temperature-resistant tempered glass inside the frame. A spotlight 14 is fixedly connected to the chamber wall above (or near) the viewing window 13. The spotlight 14 is explosion-proof, and its illumination direction is towards the dust filter bag cylinder 8 on the shelf 6, providing a light source for observation.

[0040] A soft cover 15 is fixedly connected to the wall below (or near) the viewing window 13. The soft cover 15 is made of oil-resistant and high-temperature resistant rubber.

[0041] The lens tube 16 is fixedly connected to the center of the soft cover 15. The top of the lens tube 16 has an eyepiece for observation, and the other end of the lens tube 16 extends to the area above the shelf 6.

[0042] The working principle of this utility model is as follows: Filtration process: The induced draft fan 9 starts, creating negative pressure inside the chamber 2. Dust-laden air enters the area below the middle shelf 6 of the chamber 2 through the inlet pipe 5. The air must pass through the filter layer of the dust filter bags 8 before entering the clean air chamber above the shelf 6. Dust particles are trapped on the outer surface of the dust filter bags 8, and the purified air continues to rise into the clean air chamber, finally being discharged from the outlet of the induced draft fan 9.

[0043] Dust removal process: When the dust accumulation on the surface of the filter bag cylinder 8 reaches a certain level, the induced draft fan 9 is stopped or kept running, and high-pressure gas is introduced into the main pipe 10. The high-pressure gas is distributed to each high-pressure nozzle 12 through the secondary pipe 11. The high-pressure nozzle 12 sprays high-speed airflow downwards or at an angle downwards, directly impacting the top opening of its corresponding filter bag cylinder 8. The airflow causes the filter bag cylinder 8 to shake violently, causing the dust particles attached to its surface to fall off and into the funnel 3 below. The dust accumulates in the funnel 3, and can be discharged by periodically opening the manual valve 4.

[0044] Visual monitoring process: Routine observation: The internal environment of the chamber 2, the overall arrangement of the dust filter bags 8, and the approximate dust accumulation can be directly observed through the viewing window 13.

[0045] Detailed inspection: Turn on the light 14 to provide sufficient lighting for the interior of the chamber 2, especially the dust filter bag cylinder 8.

[0046] The operator observes through the eyepiece at the top of the lens tube 16. Because the lens tube 16 is flexibly connected to the chamber 2 via the flexible cover 15, the angle and insertion depth of the lens tube 16 can be slightly adjusted while ensuring airtightness (preventing dust leakage or the entry of outside air). Through the lens tube 16, the operator can clearly and closely observe the surface condition of the dust filter bag cylinder 8 at any location: checking for damage (holes caused by tearing of the filter bag); checking for detachment (the filter bag coming loose from the flange of the positioning hole 7); checking for clogging (the surface of the filter bag is covered and blocked by wet, sticky dust); and checking the dust removal effect (the thickness of residual dust on the surface after blowing).

[0047] Once an anomaly is detected (such as damage leading to excessive emissions), it can be addressed immediately without waiting for shutdown.

[0048] Compared with the prior art, the present invention has the following advantages: This dust removal device for air pollution control features a pressure-resistant and high-temperature-resistant square viewing window 13 installed on the side wall of the clean air chamber of the silo 2 (i.e., the area above the shelf 6). A light 14 is installed near the viewing window 13 to ensure sufficient light for observation. Simultaneously, a movable lens tube 16 is provided, sealed on the outside by a rubber soft cover 15. Using the lens tube 16, personnel can quickly and intuitively observe and inspect the working status of the filter bag cylinders 8 inside the silo 2, checking for damage, detachment, or clogging, without stopping the machine or opening the silo. Any abnormalities (such as bag rupture leading to excessive emissions) can be addressed immediately, reducing equipment damage and emission risks, and effectively solving problems existing in current technologies.
