Description

Technical Field

[0001] This utility model belongs to the field of glass kiln dust removal technology, and relates to a dust removal device for glass kiln dust collectors. Background Technology

[0002] As the core equipment in glass production, glass kilns generate a large amount of dust-laden fumes during the high-temperature melting process. Direct emission of these fumes would cause serious environmental pollution, and dust accumulation would also affect the normal operating efficiency of the kiln. Therefore, they must be purified by specialized dust collectors. The filter components of the dust collector are the key to flue gas purification; their cleanliness directly determines the filtration efficiency and operational stability of the dust collection system. The dust removal device is an important supporting equipment to ensure the continuous and efficient operation of the filter components, playing an indispensable role in achieving environmentally compliant production in glass kilns.

[0003] However, in actual production scenarios, the kiln pressure of glass furnaces is easily affected by various factors such as raw material input and combustion conditions, causing fluctuations. These fluctuations disrupt the airflow stability inside the dust collector, leading to uneven dust adhesion on the surface of the filter tube assembly. Simultaneously, with prolonged operation, dust gradually accumulates in the pores and surface of the filter media, forming a caked layer. This not only significantly increases filtration resistance but also directly causes a substantial decrease in the dust collector's filtration efficiency. Furthermore, if the accumulated dust is not removed promptly and thoroughly, it accelerates the aging and damage of the filter tube assembly, increasing equipment maintenance costs and downtime for repairs. In severe cases, it can even disrupt the continuous production process of the glass furnace, causing economic losses to the enterprise.

[0004] A search reveals several solutions for cleaning dust collectors in glass kilns. A representative example is the "Dust Cleaning Device for Carrier Plate Glass Kilns" disclosed in patent CN115738512A. This device uses a PLC control unit combined with a pressure sensor, working in conjunction with an acoustic dust collector and a reverse blower to achieve cleaning. Its principle is that the reverse blower generates a counter-current airflow, causing the filter bags to undergo a "shrink-expand" morphological change. Combined with the acoustic vibration of the acoustic dust collector, this promotes the shedding of dust from the bag surface, thus solving the problem of incomplete cleaning. Besides this, traditional solutions include simple pulse-jet cleaning and mechanical vibration cleaning. These existing methods can all achieve the cleaning purpose to a certain extent. Pulse-jet cleaning has a faster response speed and is suitable for handling medium-concentration dust; mechanical vibration cleaning has a simple structure and lower equipment investment costs. However, it also has obvious drawbacks: the simple pulse jet cleaning method is poorly adaptable to kiln pressure fluctuations and is prone to uneven cleaning due to unstable airflow; the mechanical vibration cleaning method causes significant wear and tear on filter components, shortening the filter media's lifespan with long-term use; while the solution adopted by CN115738512A combines acoustic and reverse-blowing technologies, it lacks a dedicated compensation mechanism for kiln pressure fluctuations, making it difficult to fundamentally address the adverse effects of kiln pressure fluctuations on the cleaning effect. Furthermore, the ultrasonic dust collector is located outside the dust collector, limiting its effectiveness in cleaning deep-seated ash deposits inside the filter components. Therefore, this utility model proposes a cleaning device integrating dynamic kiln pressure compensation, precise cleaning, and coordinated control, aiming to effectively address the shortcomings of existing technologies and ensure the stable and efficient operation of glass kiln dust collectors. Utility Model Content

[0005] This utility model provides a dust removal device for a glass kiln dust collector, which solves the problem of decreased filtration efficiency caused by kiln pressure fluctuations and ash accumulation in the filter tube assembly during the operation of the glass kiln dust collector.

[0006] To solve the above problems, the technical solution adopted by the utility model is as follows: A dust removal device for a glass kiln dust collector, characterized in that it comprises an air inlet pipe, an air distribution box, at least one filter chamber, a dust hopper, a dust removal assembly, and a control module; a pressure compensation valve and a kiln pressure sensor are sequentially installed on the air inlet pipe, the air outlet of the air inlet pipe is connected to the air distribution box, the air distribution box is connected to the air inlet of each filter chamber through multiple air distribution pipes, and an air inlet butterfly valve is installed on each air distribution pipe; a filter tube assembly is installed in the filter chamber, a differential pressure sensor for monitoring the pressure difference of the filter tube assembly is installed on the filter chamber, the bottom of the filter chamber is connected to the dust hopper, and a vibration motor and a discharge valve are installed on the dust hopper; the dust removal assembly comprises an annular nozzle, a nozzle installed on the annular nozzle, and an ultrasonic transducer, the annular nozzle is connected to an air storage tank, the nozzle is installed one-to-one with the filter tubes in the filter tube assembly, and the ultrasonic transducer is installed on the inner wall of the filter chamber and close to the filter tube assembly; the control module coordinates the operation of the pressure compensation valve, the air inlet butterfly valve, the dust removal assembly, and the vibration motor based on feedback from the kiln pressure sensor and the differential pressure sensor.

[0007] The principle and advantages of this scheme are as follows: The kiln pressure data of the exhaust gas from the glass kiln is monitored in real time by a kiln pressure sensor on the air inlet pipe. When kiln pressure fluctuations are detected, the control module immediately provides feedback and adjusts the pressure compensation valve to stabilize the airflow pressure entering the distribution box. The distribution box distributes the airflow evenly to each filter chamber through a distribution pipe with an independent air inlet butterfly valve, ensuring that the airflow state in each filter chamber is consistent. At the same time, the differential pressure sensor on the filter chamber continuously monitors the pressure difference across the filter tube assembly. When the pressure difference exceeds the set threshold, that is, when the dust accumulation reaches the level requiring cleaning, the control module activates the cleaning component. On one hand, the air tank supplies air to the annular nozzle, which sprays directional airflow onto the inner wall of each filter tube through nozzles that are angled to the axis of the filter tube and correspond one-to-one, directly impacting the dust adhering inside the tube. On the other hand, the ultrasonic transducer close to the filter tube assembly on the inner wall of the filter chamber synchronously generates high-frequency vibration, causing the caking dust on the surface and in the pores of the filter tube to fall off, avoiding deep dust accumulation. Finally, the control module drives the vibration motor on the ash hopper to start, and together with the discharge valve, the dust that has fallen into the ash hopper is quickly discharged. The whole process achieves a seamless connection between stable kiln pressure, precise ash cleaning and ash discharge through the coordinated control of various components by the control module.

[0008] Compared to existing technologies, which lack a dedicated adjustment mechanism for kiln pressure fluctuations and rely solely on pressure sensors to monitor external pressure in the dust collector, this approach fails to address the airflow turbulence caused by kiln pressure fluctuations at its source. In contrast, this solution, through the linkage between a kiln pressure sensor and a pressure compensation valve, can offset the impact of kiln pressure fluctuations on the airflow in the filter chamber in real time. For example, when the kiln pressure increases instantaneously, the pressure compensation valve can quickly adjust the inlet resistance, preventing uneven dust adhesion in the filter tube assembly due to airflow impact and ensuring stable filtration efficiency. This is an adaptive kiln pressure adjustment effect that cannot be achieved in the prior art. Secondly, existing technologies use a combination of external acoustic dust collectors and back-blowing fans for cleaning. The acoustic waves act from outside the dust collector and have difficulty penetrating the inside of the filter bags, resulting in limited cleaning effect on deep-seated dust accumulation. Furthermore, the back-blowing fan's "shrink-expand" cleaning of the filter bags easily causes bag wear. In contrast, the ultrasonic transducer in this solution is directly installed on the inner wall of the filter chamber and close to the filter tube assembly. The high-frequency vibration can directly act on the surface and inside of the filter tubes. Combined with the airflow impact of the directional angle nozzles, it can thoroughly remove the caking dust in the pores. For example, for highly viscous dust in glass kiln flue gas, the amount of dust residue in this solution can be reduced compared to the comparative paper. At the same time, it avoids fatigue wear caused by repeated shape changes of the filter components, extending the service life of the filter media. Existing technologies do not achieve independent control of each compartment, and the filter chamber status needs to be switched during the dust removal process, which may lead to local filtration interruption. This solution, through the independent air inlet butterfly valve on the air distribution pipe, can achieve staggered operation of single-compartment dust removal while other compartments continue normal filtration. For example, when a filter chamber starts dust removal, the control module closes the air inlet butterfly valve of that chamber, while other filter chambers maintain normal air intake filtration, ensuring continuous operation of the entire dust removal system without downtime for dust removal. This continuous operation advantage can further ensure the production continuity of the glass kiln and reduce production losses caused by dust removal interruptions.

[0009] Furthermore, the filter tube assembly consists of multiple filter tubes arranged in a matrix, and the filter tubes are P84 / PTFE composite filter tubes with a temperature resistance of [temperature value missing]. The matrix arrangement maximizes the utilization of the filtration area within the limited filter chamber space, ensuring full contact between the airflow and the filter tube surface, improving filtration efficiency per unit time, and facilitating uniform airflow distribution, avoiding uneven dust accumulation caused by localized airflow concentration; while selecting a temperature resistant... of Composite filter tubes are perfectly suited to the high-temperature characteristics of glass kiln flue gas, effectively resisting the erosion caused by high-temperature flue gas and avoiding the problems of deformation and aging of traditional filter materials under high-temperature environments, thus significantly extending the service life of the filter tubes. Furthermore, this composite filter material not only boasts excellent high-temperature resistance but also possesses good chemical stability and anti-dust adhesion capabilities. It can effectively cope with corrosive components that may be present in glass kiln flue gas, reducing the formation of caking layers and lowering the difficulty of dust removal. Simultaneously, its stable high-temperature resistance ensures that the dust collector can still operate normally when fluctuating kiln operating conditions cause a sudden increase in flue gas temperature, avoiding downtime for maintenance due to filter tube damage. This further enhances the operational stability and reliability of the entire dust removal system, meeting the stringent requirements of continuous high-temperature production in glass kilns.

[0010] Furthermore, the frequency of the ultrasonic transducer is The distance between the ultrasonic transducer and the filter tube assembly is The ultrasonic vibration energy in this frequency range is concentrated and has strong penetrating power. It can effectively break the adsorption force and agglomeration structure of dust on the surface and in the pores of the filter tube assembly, promoting the rapid shedding of deep-seated dust and avoiding the problem of incomplete cleaning by traditional low-frequency vibration. Furthermore, it avoids fatigue damage to the filter media caused by excessively high frequencies, ensuring the long-term stable use of the filter components. The precise spacing ensures that ultrasonic vibrations are efficiently transmitted to each filter tube. This avoids damage caused by excessive local vibration energy due to overly close spacing, while also preventing vibration energy attenuation due to overly large spacing. This ensures that all filter tubes receive uniform vibration, achieving comprehensive dust removal. This precise parameter matching allows the ultrasonic transducer to synergize with the directional airflow of the annular nozzle, significantly improving dust removal efficiency. Especially for highly viscous dust in glass kiln flue gas, it effectively reduces dust residue, lowers energy consumption and equipment wear during the dust removal process, and further guarantees the efficient and stable operation of the dust removal system.

[0011] Furthermore, the number of the gas distribution pipes is: Each of the air distribution pipes corresponds to one filter chamber, and the distance between adjacent filter chambers is [missing information]. , The configuration of individual gas distribution pipes allows for the rational diversion of flue gas. Combined with the independent inlet butterfly valve corresponding to each distribution pipe, it can precisely control the airflow into each filter chamber, ensuring that cleaning of a single chamber does not affect the normal operation of other filter chambers. This achieves a balance between staggered cleaning and continuous filtration, avoiding dust removal interruptions caused by overall shutdown for cleaning. The spacing between adjacent filter chambers provides ample operating space for installation and maintenance, facilitating future upkeep. Furthermore, it effectively prevents airflow interference and secondary dust re-entrainment between adjacent chambers during cleaning, ensuring stable airflow within each chamber and improving dust filtration and cleaning efficiency. This parameter combination guarantees the overall processing capacity of the dust removal system while optimizing its structural layout to enhance operational flexibility and maintenance convenience, perfectly meeting the stringent requirements of continuous glass kiln production for dust removal equipment.

[0012] Furthermore, there are two pressure compensation valves, one located at the upstream end of the intake pipe and the other at the outlet end of the filter chamber. The adjustment accuracy of the pressure compensation valves is [insert accuracy here]. The pressure compensation valve at the upstream end of the inlet pipe can directly address the original fluctuations in kiln pressure, calibrating the pressure from the source of flue gas entering the dust removal system to ensure stable airflow pressure entering the distribution box; the pressure compensation valve at the outlet end of the filter chamber can correct local pressure deviations caused by dust accumulation and cleaning operations during single-chamber filtration in real time, ensuring the consistency of airflow state inside each filter chamber. Its high-precision adjustment capability can sensitively detect minute pressure changes and respond quickly, avoiding the airflow turbulence caused by the lag in adjustment of traditional low-precision valves. This effectively prevents uneven dust adhesion and sudden changes in filtration resistance caused by pressure fluctuations. This bidirectional high-precision pressure control design not only ensures the stable operation of the dust removal system throughout the entire process but also further improves the filtration efficiency and dust removal effect of the filter tube assembly, extends the service life of the filter media, and adapts to the complex and ever-changing operating conditions of glass kilns, providing a solid pressure guarantee for the efficient and reliable operation of the entire dust removal system.

[0013] Furthermore, the outer wall of the filter chamber is equipped with an electric heating belt, and the temperature of the electric heating belt is controlled at... The electric heating belt starts and stops synchronously with the air inlet butterfly valve and the air outlet control valve. The temperature range effectively raises the internal temperature of the filter chamber, preventing condensation of water vapor on the filter tube surface due to a sudden temperature drop after high-temperature flue gas enters the chamber. This prevents dust and water vapor from combining to form a difficult-to-remove adhesive layer, while also enhancing dust flowability and reducing its adhesion to the filter media surface, thus simplifying subsequent cleaning operations. The synchronized start-stop design of the electric heating belt with the inlet butterfly valve and outlet control valve enables precise coordination between heating and filtration operations. When the valves are open and the filter chamber is put into use, the electric heating belt starts simultaneously, ensuring the filter chamber maintains a stable and suitable temperature throughout the entire working cycle; when the valves are closed and the filter chamber stops operating, the electric heating belt shuts off simultaneously, avoiding energy waste. This design not only ensures the filtration efficiency and cleaning effect of the filter tube assembly but also achieves energy-saving goals through precise start-stop control, effectively extending the service life of the filter tube assembly and further enhancing the overall dust removal system's ability to adapt to complex operating conditions.

[0014] Furthermore, the gas storage tank is connected to the annular nozzle via a one-way valve, and the volume of the gas storage tank is [missing information]. The pressure after the blow can be recovered. The residual compressed air, with its one-way valve, effectively prevents the backflow of residual air and potentially entrained dust from the annular nozzle into the air tank, avoiding contamination of the clean compressed air within. This also protects internal components from wear, ensuring air quality and equipment safety. The air tank with residual air recovery function collects and stores the compressed air that is not fully released after each cleaning cycle, instead of directly discharging it. This significantly reduces compressed air waste, lowers the continuous air production load on the air compressor, and thus saves energy. Especially for the frequent start-stop cleaning operations of glass kiln dust collectors, this recovery design improves compressed air utilization, significantly reducing production costs in the long run. Furthermore, the recovered residual compressed air can provide some air for the next cleaning operation, shortening the air tank replenishment time, ensuring rapid response during cleaning operations, and further improving the overall efficiency and economy of the cleaning system.

[0015] Furthermore, the control module includes a controller based on a fuzzy control algorithm, which dynamically adjusts the cleaning frequency according to the differential pressure change rate and kiln pressure fluctuation value. The blowing pressure is The fuzzy control algorithm can accurately capture the dust accumulation rate reflected by the differential pressure change rate, as well as the airflow stability changes caused by kiln pressure fluctuations. Through rapid analysis and output of optimal control commands via the algorithm model, it avoids the problems of over-cleaning or untimely cleaning caused by traditional fixed-frequency cleaning. When dust accumulates rapidly (large differential pressure change rate) or kiln pressure fluctuates drastically, the cleaning frequency is automatically increased to ensure stable filtration resistance; when the operating conditions are stable and dust accumulation is slow, the cleaning frequency is reduced to decrease energy consumption and equipment wear. The 0.4-0.6MPa jet pressure range provides sufficient airflow impact force to remove dust from the filter tube surface and pores without damaging the filter tube assembly due to excessive pressure, thus balancing cleaning effectiveness and equipment protection.

Kiln pressure sensor; 7. Gas distribution box; 8. Gas distribution pipe; 9. Differential pressure sensor; 10. Air inlet butterfly valve; 11. Air storage tank; 12. Vibration motor; 13. Discharge valve; 14. Ultrasonic vibrator; 15. Nozzle; 16. Annular nozzle; 17. Control module. Example 1 like Figure 1-4 As shown, a dust removal device for a glass kiln dust collector includes an inlet pipe 4, a distribution box 7, five filter chambers 1, a dust hopper 3, a dust removal assembly, and a control module 17. Two pressure compensation valves 5 and a kiln pressure sensor 6 are sequentially installed on the inlet pipe 4 along the airflow direction. The two pressure compensation valves 5 are respectively located at the upstream end of the inlet pipe 4 and the outlet end of the filter chamber 1, enabling precise response to kiln pressure fluctuations. The outlet end of the inlet pipe 4 is fixedly connected to the distribution box 7 via a flange. The distribution box 7 is connected to the inlet end of each filter chamber 1 via distribution pipes 8. Each distribution pipe 8 is equipped with an inlet butterfly valve 10. The distance between adjacent filter chambers 1 is set to 1.2m, which facilitates equipment installation and maintenance while avoiding airflow interference during dust removal.

[0021] Each filter chamber 1 is equipped with a filter tube assembly 2, which consists of multiple P84 / PTFE composite filter tubes arranged in a matrix. The temperature resistance of this composite filter tube is [temperature value missing]. It can be adapted to the filtration requirements of high-temperature flue gas in glass kilns. A differential pressure sensor 9 is installed on the side wall of the filter chamber 1 to monitor the pressure difference changes on both sides of the filter tube assembly 2 in real time. The bottom of the filter chamber 1 is welded and fixed to the ash hopper 3. A vibration motor 12 is installed on the outer side wall of the ash hopper 3, and a discharge valve 13 is set at the bottom to facilitate the rapid removal of detached dust.

[0022] The dust removal assembly includes an annular nozzle 16, a nozzle 15, and an ultrasonic transducer 14. The annular nozzle 16 is connected to an air storage tank 11 via a pipe, and a one-way valve is installed on the pipe to prevent airflow backflow. The volume of the air storage tank 11 is... The pressure after the blow can be recovered. To save energy, the residual compressed air in the storage tank is connected to the annular nozzle via a pipe equipped with a one-way valve. The one-way valve has a directional flow characteristic, allowing airflow only from the annular nozzle to the storage tank, preventing reverse leakage of airflow when the storage tank supplies air to the annular nozzle during the dust removal and purging phase. During dust removal, the storage tank supplies 0.4-0.6 MPa compressed air to the annular nozzle, which is then sprayed through the nozzle to clean the dust accumulation in the filter tube. After purging, residual compressed air with a pressure ≥0.2 MPa remains in the annular nozzle. At this time, the residual pressure in the annular nozzle is higher than the relatively low pressure state formed by the previous air supply in the storage tank. Driven by this pressure difference, the residual compressed air in the annular nozzle will push the one-way valve to open in the forward direction, flowing back along the connecting pipe to the storage tank. The compressed air is recycled within the storage tank. The residual compressed air can be stored in the storage tank, replenishing the air volume and reducing the external air compressor's air supply load to lower energy consumption. It also provides a quick auxiliary air source for the next dust removal operation, adapting to the 30-60s high-frequency dust removal requirements and achieving compressed air recycling. Nozzles 15 are evenly distributed on the annular nozzle 16, forming a 35° angle with the axis of each filter tube in the filter tube assembly 2, and are set one-to-one, enabling precise airflow to impact the accumulated dust inside the tubes. The ultrasonic transducer 14 is fixedly installed on the inner wall of the filter chamber 1, close to the filter tube assembly 2. Its operating frequency is 35kHz, and the distance between it and the filter tube assembly 2 is set to 80mm, effectively promoting the shedding of clumped dust.

[0023] The outer wall of filter chamber 1 is wrapped with an electric heating belt, and the temperature of the electric heating belt is controlled at... It synchronizes its start and stop with the inlet butterfly valve 10 and the outlet control valve to prevent water vapor condensation caused by a sudden drop in flue gas temperature. The control module 17 uses a fuzzy control algorithm-based controller, installed on the outside of the filter chamber 1. It is electrically connected to components such as the kiln pressure sensor 6, differential pressure sensor 9, pressure compensation valve 5, inlet butterfly valve 10, ultrasonic vibrator 14, vibration motor 12, and control valves of the air storage tank 11 via wiring. It can dynamically adjust the cleaning frequency based on the differential pressure change rate and kiln pressure fluctuation value. The blowing pressure is .

[0024] The working process of this embodiment is as follows: Airflow stabilization control: Dust-laden flue gas generated by the glass furnace enters through the inlet pipe 4. The kiln pressure sensor 6 monitors the kiln pressure data in real time and feeds it back to the control module 17. When a kiln pressure fluctuation is detected, the control module 17 immediately adjusts the pressure compensation valves 5 at the upstream end of the inlet pipe 4 and the outlet end of the filter chamber 1 to ensure stable airflow pressure entering the distribution box 7. The distribution box 7 distributes the airflow evenly to each filter chamber 1 through the inlet butterfly valves 10 on each distribution pipe 8.

[0025] Filtration and differential pressure monitoring: After the dust-laden flue gas enters the filter chamber 1, it is filtered by the filter tube group 2, and the dust is trapped and adhered to the surface of the filter tube. The differential pressure sensor 9 continuously monitors the pressure difference across the filter tube assembly 2 and transmits the data to the control module 17. When the pressure difference exceeds a set threshold, the dust removal program is triggered. The filter tube assembly 2 consists of multiple P84 / PTFE composite filter tubes with micropores arranged in a matrix. The composite filter tubes can trap dust particles in the flue gas through the pores while allowing airflow, which is the basis for filtration. The filter chamber is designed with a side-wall air inlet and side-wall air outlet path. After the dust-laden flue gas enters from the side-wall air inlet of the filter chamber, it is dispersed and guided by the matrix-arranged filter tube assembly, forcing the filter material through the filter tubes to complete the air-dust separation. The dust adheres to the surface of the filter tubes, and the clean airflow passes through the filter tubes and is discharged from the side-wall air outlet. The matrix arrangement can also maximize the use of the filter chamber space, ensure that the airflow and the filter tubes are in full contact, and avoid short circuits. At the same time, the differential pressure sensor 9 monitors the pressure difference across the filter tube assembly 2. When the pressure difference exceeds the threshold, the dust removal program is triggered.

[0026] Collaborative dust removal operation: Control module 17 activates the dust removal assembly, and air tank 11 supplies compressed air to annular nozzle 16. Directional airflow is then sprayed through nozzle 15 onto the inner wall of the filter tube, impacting the accumulated dust inside. Simultaneously, ultrasonic transducer 14 activates to generate high-frequency vibration, causing the clumps of dust on the surface and within the pores of the filter tube to detach. During this process, the electric heating belt remains operational, enhancing dust flowability.

[0027] Dust discharge: The control module 17 drives the vibration motor 12 on the dust hopper 3 to start, and in conjunction with opening the discharge valve 13, the dust that has fallen into the dust hopper 3 is quickly discharged. During the dust removal process, the dust removal can be carried out in a staggered manner by closing the inlet butterfly valve 10 of the corresponding air distribution pipe 8, while the remaining chambers are filtered normally, thus ensuring the continuous operation of the dust removal system.

[0028] Residual air recovery: After pulse-jet cleaning, pressure The residual compressed air is returned to the air storage tank 11 through the pipeline for recycling, reducing energy consumption.

[0029] Once the kiln pressure stabilizes and the pressure difference of filter tube group 2 drops to the normal range, the control module 17 adjusts each component to return to the normal filtration state, completing one ash cleaning cycle.

[0030] Example 2 The difference between this embodiment and Embodiment 1 is that the number of air distribution pipes 8 is set to 4, corresponding to 4 filter chambers 1, and the spacing between adjacent filter chambers 1 is 1m; the frequency of the ultrasonic transducer 14 is... The distance between the gas storage tank 11 and the filter tube assembly 2 is 50mm; the volume of the gas storage tank 11 is... The controlled temperature of the electric heating belt is The dust removal frequency adjustment range set by control module 17 is: The injection pressure adjustment range is: This configuration is suitable for dust removal and cleaning needs of small and medium-sized glass kilns, and further reduces equipment energy consumption while ensuring the cleaning effect.

[0031] Example 3 The difference between this embodiment and Embodiment 1 is that the number of air distribution pipes 8 is set to 6, corresponding to 6 filter chambers 1, and the spacing between adjacent filter chambers 1 is [missing information]. The frequency of the ultrasonic transducer 14 is The distance between the filter tube group 2 and the filter tube group 2 is The volume of gas storage tank 11 is The controlled temperature of the electric heating belt is The dust removal frequency adjustment range set by control module 17 is: The injection pressure adjustment range is: This configuration is suitable for large glass kilns or high-dust flue gas conditions, and can improve the overall dust removal efficiency to meet the needs of high-intensity operations.
