DETAILED DESCRIPTION

[0021] It should be noted that the embodiments and features in the present application can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0022] Please refer toFigure 1 and Figure 2 The application provides a dust removal device, which comprises a device shell 100, a dust removal chamber 101 arranged in the device shell 100, an air inlet 110 and an air outlet 120 arranged on the device shell 100, a spraying assembly 200 arranged in the dust removal chamber 101, the spraying assembly 200 comprising a first liquid inlet 201 and a second liquid inlet 202, the first liquid inlet 201 being used for connecting to a water source, and the second liquid inlet 202 being used for connecting to an anti-freezing liquid, and a first filter component 300 arranged in the dust removal chamber 101, the spraying assembly 200 being opposite to the first filter component 300, the spraying assembly 200 being used for spraying the water source or the anti-freezing liquid on the first filter component 300, and the airflow flowing through the first filter component 300 after being introduced into the air inlet 110 being discharged through the air outlet 120.

[0023] According to the dust removal device provided by the application, the device shell 100, the spraying assembly 200 and the first filter component 300 are provided, the dust removal chamber 101 is arranged in the device shell 100, the air inlet 110 and the air outlet 120 are arranged on the device shell 100, the spraying assembly 200 is arranged in the dust removal chamber 101, the spraying assembly 200 comprises the first liquid inlet 201 and the second liquid inlet 202, the first liquid inlet 201 is used for connecting to the water source, the second liquid inlet 202 is used for connecting to the anti-freezing liquid, the first filter component 300 is arranged in the dust removal chamber 101, the spraying assembly 200 is opposite to the first filter component 300, the spraying assembly 200 is used for spraying the water source or the anti-freezing liquid on the first filter component 300, and the airflow flowing through the first filter component 300 after being introduced into the air inlet 110 is discharged through the air outlet 120. The spraying assembly can automatically select the water source or the anti-freezing liquid for atomization according to the ambient temperature, and the spraying assembly is used in cooperation with the first filter component, so that the dust capture efficiency is greatly improved. The high-precision filtering design of the first filter component ensures that the dust is completely removed, and the damage of the dust to the environment and the device is reduced. The device can effectively operate in an extremely cold environment of 0℃ to -40℃, solves the problem that the traditional wet dust removal method fails due to water icing in a low-temperature condition, and ensures that the mine area can still effectively control dust in winter.

[0024] By using the anti-freezing liquid, the freezing and sticking phenomenon of the device in an extremely cold condition is effectively prevented, the key devices such as the belt conveying system are protected, the service life of the key devices is prolonged, and the replacement and maintenance costs are reduced.

[0025] Specifically, as Figure 1As shown, the dust removal device further comprises: a first pipe communicating with the first liquid inlet 201 for supplying water into the spraying assembly 200, the first pipe being provided with a first control valve for controlling the opening and closing of the first pipe; and a second pipe communicating with the second liquid inlet 202 for supplying antifreeze into the spraying assembly 200, the second pipe being provided with a second control valve for controlling the opening and closing of the second pipe. Through automatic or manual control of the first control valve and the second control valve, the dust removal device can intelligently switch between water supply and antifreeze supply when the temperature changes, ensuring efficient dust removal performance under different temperature conditions. When the temperature is higher than 0℃, the device supplies water through the first pipe for wet dust removal with lower cost; when the temperature is lower than 0℃, the device automatically switches to supply antifreeze through the second pipe to avoid the freezing of water mist after atomization, affecting the dust removal effect and equipment operation, while the antifreeze is recycled, reducing the operating cost.

[0026] In the specific implementation process, the dust removal device further comprises: a recovery pipeline 400; and a recovery tank 500, both ends of the recovery pipeline 400 communicating with the dust falling chamber 101 and the recovery tank 500 respectively, so that the mixture after dust falling of the water source or the antifreeze is recovered into the recovery tank 500 through the recovery pipeline 400. Through the recovery pipeline 400 and the recovery tank 500, the water source or the antifreeze after dust falling can be collected and purified for reuse in the wet dust removal process. This avoids the waste of liquid, especially when the antifreeze with higher cost is used, which can greatly reduce the operating cost. Recycling and reusing the water source or the antifreeze reduces the impact on the environment and avoids pollution caused by direct discharge of a large amount of liquid into water bodies. At the same time, through the efficient filtration of the second filter component, the cleanliness of the recovered liquid is ensured, and the complexity and cost of subsequent treatment are reduced.

[0027] Through the antifreeze circulation system, the risk of damage to the equipment due to water freezing in extremely cold conditions is avoided, thereby prolonging the service life of the equipment, especially for the protection of key transportation equipment such as the belt conveyor, reducing the production interruption and maintenance cost caused by equipment damage.

[0028] The dust removal device further comprises: a second filter component 600 arranged in the recovery tank 500, the second filter component 600 dividing the recovery tank 500 into a sedimentation tank body 510 and a clean tank body 520; the recovery pipeline 400 communicating with the sedimentation tank body 510, the water source or the antifreeze in the sedimentation tank body 510 penetrating into the clean tank body 520 after passing through the second filter component 600. The arrangement of the second filter component 600 effectively utilizes the dual mechanisms of gravity settling and filtration separation, which can efficiently separate the dust in the mixture after dust falling from the liquid (water source or antifreeze), ensuring that the dust content in the liquid is extremely low and improving the purification effect of the system.

[0029] By dividing the recovery tank 500 into the sedimentation tank body 510 and the cleaning tank body 520, the sedimentation tank body 510 is used to collect and precipitate the dust in the mixture, and the cleaning tank body 520 is used to store the filtered cleaning liquid. This design can realize the recycling of the liquid and reduce the operation cost of the wet dust removal equipment.

[0030] In the specific implementation process, the recovery tank 500 includes oppositely arranged first and second inner wall surfaces, the first inner wall surface is provided with a first sliding groove, the second inner wall surface is provided with a second sliding groove, and the two ends of the second filter component 600 are respectively inserted into the first and second sliding grooves. The sliding groove design makes the installation and replacement of the second filter component 600 very simple. Maintenance personnel do not need complex tools and long disassembly and assembly process, and only need to slide the second filter component into or out of the sliding groove to complete it. This not only saves maintenance time, but also reduces maintenance cost. The sliding groove can provide stable support for the second filter component to avoid displacement or deformation under the action of liquid flow or dust impact, ensuring the structural stability of the filter component and the reliability of the filtering effect.

[0031] The second filter component 600 can be easily taken out of the recovery tank for cleaning or replacement. This design ensures that the filter component maintains good cleanliness, thereby prolonging the service life of the equipment and reducing maintenance problems caused by filter component blockage. The sliding groove design allows the second filter component to be replaced according to actual needs, such as quickly replacing filter components with different mesh densities when the dust particle size changes, improving the adaptability and flexibility of the equipment.

[0032] The dust removal equipment also includes a circulation pipeline 700, the two ends of the circulation pipeline 700 are respectively communicated with the cleaning tank body 520 and the second liquid inlet 202; and a third control valve is arranged on the circulation pipeline 700, the third control valve is communicated with the circulation pipeline 700, and the opening and closing of the circulation pipeline 700 is controlled through the third control valve. The arrangement of the circulation pipeline 700 enables the antifreeze liquid filtered by the second filter component to be directly pumped back to the spraying assembly from the cleaning tank body 520, realizing the rapid recycling of the antifreeze liquid, reducing the storage amount requirement of the antifreeze liquid, and also reducing the consumption of fresh antifreeze liquid by the system, further reducing the operation cost. The arrangement of the third control valve makes the operation of the equipment more flexible. When antifreeze liquid is needed for dust removal, the circulation pipeline 700 can be opened through the control valve to make the antifreeze liquid circulate smoothly; and when water can be used for dust removal due to temperature, the third control valve can be closed to stop the circulation of the antifreeze liquid, so as to switch to the water source circulation system, and automatically adjust the type of dust removal liquid according to environmental changes.

[0033] The combination of the circulation pipeline 700 and the third control valve ensures stable supply of antifreeze in extremely cold conditions, reduces system instability factors caused by temperature changes, and improves the reliability and continuous operation capability of the entire dust removal equipment.

[0034] Further, the dust removal equipment further comprises: a power component 710 arranged on the circulation pipeline 700 and in communication with the circulation pipeline 700; and a third filtering component 720 arranged on the circulation pipeline 700 and in communication with the circulation pipeline 700, the third filtering component 720 being located at the liquid outlet end of the power component 710, and the antifreeze or water source in the cleaning pool body 520 flows back to the second liquid inlet 202 after passing through the third filtering component 720. The addition of the power component 710 (such as a pump) provides stable power for the circulation of the antifreeze or water source, ensuring continuous supply of liquid from the cleaning pool body 520 to the spray assembly 200, and ensuring sufficient liquid amount for efficient wet dust removal even in extremely cold conditions. The third filtering component 720 is located at the liquid outlet end of the power component 710, further filtering the liquid flowing back to the spray assembly, ensuring that the antifreeze or water source does not decrease its performance, such as the antifreeze effect of the antifreeze and the atomization effect of the spray assembly, during the circulation process. By fine filtering the antifreeze or water source in the circulation through the third filtering component, the wear of the spray assembly and the power component caused by solid impurities is reduced, the equipment failure rate is reduced, and the service life of the equipment is prolonged.

[0035] Improved dust removal efficiency: the addition of the third filtering component not only improves the purity of the liquid, but also optimizes the performance of the entire wet dust removal equipment, because clean liquid is easier to atomize and can form more uniform droplets in the dust removal chamber 101, thereby improving dust capture efficiency and improving air quality.

[0036] The dust removal equipment further comprises: a blowdown pipeline 800 in communication with the sedimentation pool body 510, the mixture settled in the sedimentation pool body 510 being discharged through the blowdown pipeline 800; and a fourth control valve 810 arranged on the blowdown pipeline 800 and in communication with the blowdown pipeline 800, the blowdown pipeline 800 being controlled by the fourth control valve 810. Through the blowdown pipeline 800, the mixture (including dust and impurities) settled in the sedimentation pool body 510 is periodically discharged, avoiding the problem of excessive accumulation of sediment in the pool body, which leads to decreased filtration efficiency or equipment blockage. This not only simplifies the maintenance work of the equipment, but also ensures long-term stable operation of the equipment. The fourth control valve 810 can be linked with the control system of the equipment, and the blowdown pipeline can be automatically opened or closed according to the amount of sediment in the sedimentation pool or the regular maintenance time, realizing automatic management of the equipment, reducing the need for manual operation, and improving work efficiency.

[0037] In the present application, the device housing 100 is provided with a liquid outlet 130, and a dust falling chamber 101 is provided with a flow guide channel, one end of which is arranged below the spray assembly 200, and the other end is inclined towards the direction of the liquid outlet 130. The design of the flow guide channel can guide the liquid (water or antifreeze) after dust falling to flow smoothly to the liquid outlet 130, ensuring that the liquid can be quickly and completely discharged from the dust falling chamber, avoiding the accumulation of liquid in the chamber, thereby reducing the secondary pollution and equipment corrosion risk caused by liquid accumulation. At the same time, the liquid directly enters the recovery pipeline or discharge system through the liquid outlet 130, simplifying the liquid recovery process and improving the recovery efficiency. The liquid can be quickly discharged, reducing the residence time in the dust falling chamber and reducing the humidity in the chamber, which helps to reduce the corrosion of the internal structure of the equipment.

[0038] In extremely cold environments, preventing liquid accumulation in the dust falling chamber is crucial for the stable operation of the equipment. The flow guide channel and inclined design help to quickly discharge the liquid after dust falling, avoiding the liquid from freezing or icing due to low temperature, protecting the equipment from freezing damage and enhancing the safety of the equipment in extremely cold conditions.

[0039] The dust removal equipment also includes a vibration component arranged on and attached to the first filter component 300, which is used to generate an amplitude to drive the first filter component 300 to vibrate. During vibration, the first filter component 300 will shake off the water and coal slurry attached to it onto the flow guide channel, and then discharge along the flow guide channel. Vibration can effectively prevent dust accumulation on the first filter component, reduce the blockage of the filter mesh, and ensure the sustained high filtration efficiency of the filter component. Through periodic or continuous slight vibration, dust can be more easily removed from the filter material, avoiding the problem of declining filtration efficiency over time.

[0040] In extremely cold regions, liquid is prone to freeze, and the vibration component can prevent water and coal slurry from freezing on the first filter component, reducing the damage to the component and system failure caused by freezing, and ensuring the long-term stable operation of the equipment. Vibration makes it easier for water and coal slurry attached to the first filter component to fall off and flow smoothly along the flow guide channel, avoiding the accumulation of liquid in the equipment, reducing the risk of secondary pollution caused by liquid accumulation, and optimizing the liquid recovery process and improving resource utilization. The efficient vibration and cleaning of the first filter component 300 not only reduce the burden on the subsequent second filter component, but also improve the liquid circulation and purification efficiency of the entire system, enhancing the environmental adaptability and sustainability of the equipment.

[0041] Optionally, the first filter component 300 and the second filter component 600 are filter screens, the third filter component 720 is a filter, and the vibration component is an ultrasonic generator or a rotary vibrator.

[0042] The dust removal equipment provided by the application solves the problem of wet dust removal in winter in cold regions, guarantees the running time and dust removal efficiency, reduces the operation and maintenance cost, prevents the equipment from being frozen and stuck, prolongs the service life of the belt conveying system, and lays a solid foundation for further comprehensive treatment and research on the problems of wet dust removal and equipment freezing in large and super-large open-pit mine belt systems in similar conditions in winter, so that the stripping process of open-pit mines in high-cold regions can continue in winter.

[0043] In the dust removal equipment, the negative pressure air wet dust removal method is adopted, the anti-freezing liquid is used for atomization dust removal, the anti-freezing liquid is directly recycled, filtered and then enters the anti-freezing liquid tank, and then is conveyed through the anti-freezing liquid station and enters the atomization assembly to play the anti-freezing and sticking effect on the mining equipment.

[0044] When the temperature is greater than 0 DEG C, water can be used as the atomization liquid of the dust removal fan, and the water slurry can be directly discharged; when the temperature is less than 0 DEG C, the anti-freezing liquid is used as the atomization liquid of the dust removal fan, the anti-freezing liquid is recycled by the recycling device and reused, and the economic cost is reduced.

[0045] The dust-containing air is collected, the wet atomization dust removal fan is used as a negative pressure equipment, is connected with the dust-containing closed space through a pipeline, and under the negative pressure effect of the dust removal fan, the dust-containing air is extracted to reduce the dust concentration.

[0046] In winter, the atomization liquid of the wet atomization dust removal fan is the anti-freezing liquid, the dust is captured by the atomized anti-freezing liquid in the fan, is filtered through the vibrating string net and is discharged into the anti-freezing liquid recycling device in the form of water slurry, and the purified air is directly discharged to the outdoor.

[0047] The recycled anti-freezing liquid is used continuously after sedimentation and filtration, and the anti-freezing liquid pump (power component 710) is used as a power source to make the anti-freezing liquid sequentially pass through the filter, the circulation pipeline, the wet dust removal fan, the recycling pipeline and the recycling pool to form a circulation loop.
