Description

Technical Field

[0001] This utility model relates to the field of industrial dust removal technology, specifically an energy-saving wet industrial dust removal device. Background Technology

[0002] Industrial production processes generate a large amount of waste gas containing dust. In order to reduce the harm of dust to the environment and human health, wet industrial dust collection devices are widely used.

[0003] Traditional wet industrial dust collection systems utilize water resources in a rather inefficient manner. Most of the water used in the spray system is discharged directly without a proper recycling or filtration mechanism, resulting in significant water waste. Even in some systems that attempt to recycle water, the lack of efficient filtration methods, such as multi-layered, finely filtered water filters, makes it difficult to guarantee the quality of the recycled water, hindering truly effective water recycling. This not only increases water costs for businesses but also contradicts environmental protection principles and the requirements of sustainable development.

[0004] Therefore, it is necessary to design an energy-saving wet industrial dust removal device to solve the problems mentioned above. Summary of the Invention

[0008] The dust collector housing is equipped with multiple layers of staggered water filter screens located inside and above the waste hopper, with the mesh openings of adjacent layers of water filter screens being staggered.

[0009] As a preferred embodiment of this utility model, both the output fan and the input fan are driven by variable frequency motors.

[0010] As a preferred embodiment of this utility model, a water quality monitoring sensor is installed inside the water tank. The water quality monitoring sensor is electrically connected to the control device and is used to monitor the acidity, alkalinity and turbidity of the water in the water tank in real time. When the water quality does not meet the standards, the control device issues an alarm and starts the water quality treatment program.

[0011] As a preferred embodiment of this utility model, the inner wall of the waste hopper is provided with an inclined guide plate with an inclination angle of 30°-45°, which can guide dust and sewage to flow smoothly into the circulating water pump and prevent waste from accumulating in the waste hopper.

[0012] As a preferred embodiment of this utility model, the output end of the input fan is connected to the internal casing of the dust collector and a filter cartridge is installed thereon for preliminary filtration of large dust particles in the gas input into the dust collector.

[0013] As a preferred embodiment of this utility model, the circulation pipe is equipped with a flow regulating valve and a filter. The flow regulating valve is used to regulate the flow rate of the circulating water, and the filter adopts a high-precision filter screen, which can filter impurities in the circulating water, prevent impurities from entering the water tank and spray pipe, and ensure the cleanliness of the circulating water.

[0014] As a preferred embodiment of this utility model, the control device includes a PLC controller, a display screen, and operation buttons.

[0015] As a preferred embodiment of this utility model, a temperature sensor and a humidity sensor are also installed inside the dust removal box.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model, through the design of an energy-saving wet industrial dust collector, achieves the following effects: 1. This device uses a multi-layered, staggered water filter with misaligned mesh to efficiently filter the sprayed wastewater, effectively intercepting dust and other impurities.

The output and input fans are driven by variable frequency motors. The control device is electrically connected to the variable frequency motors, enabling real-time adjustment of the fan speed based on the pressure and gas flow data within the dust collector chamber. When the gas flow is low, the fan speed is automatically reduced to decrease energy consumption; when the gas flow is high, the speed is appropriately increased to ensure effective dust removal. This intelligent adjustment method avoids energy waste caused by continuous high-power operation of the fan, achieving energy-saving operation and reducing the company's energy costs; 3. The inner wall of the waste hopper is equipped with inclined guide plates with an inclination angle of 30-45°, which can guide dust and sewage to flow smoothly into the circulating water pump, effectively preventing waste from accumulating in the waste hopper, ensuring the cleanliness of the equipment interior, maintaining the normal operation of the equipment, and reducing the risk of failure caused by waste accumulation; 4.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] For examples, please refer to Figure 1-4 This utility model provides a technical solution:

[0028] An energy-saving wet industrial dust collector includes a dust collection box 1. A support frame 2 is fixedly installed at the bottom of the dust collection box 1, and a removable sealing plate 3 is installed at the top of the dust collection box 1. An output fan 4 and an input fan 5 are respectively installed on the left and right sides of the dust collection box 1. A water tank 6 is installed at the rear of the support frame 2. A spray pipe 8 is installed inside the dust collection box 1 through a water delivery pipe 7 at the upper output end of the water tank 6. A micro-drive pump 9 for powering the water is also installed on the spray pipe 8. A waste hopper 10 is installed at the bottom of the dust collection box 1, and a circulating water pump 11 is connected to the lower output end of the waste hopper 10. The other side of pump 11 is connected to the inside of water tank 6 through circulation pipe 12. Control device 13 is also fixedly installed on the base surface of dust collector 1. Bracket 2 supports dust collector 1, and removable sealing plate 3 covers the top of dust collector 1 for easy equipment inspection and maintenance. Input fan 5 sends dust-laden gas into dust collector 1, and output fan 4 discharges purified gas. Water in water tank 6 is pressurized by micro drive pump 9 through water delivery pipe 7 and sent to spray pipe 8 for spray dust removal. Wastewater after dust removal falls into waste hopper 10 and is then sent back to water tank 6 by circulating water pump 11 through circulation pipe 12. Control device 13 is responsible for coordinating the operation of each component.

[0029] Specifically, a multi-layered water filter screen 14 is installed inside the dust collector 1 and above the waste hopper 10, with the mesh openings of adjacent layers of water filter screen 14 being staggered. During the fall of the sprayed wastewater, it first passes through the multi-layered water filter screen 14 above the waste hopper 10 inside the dust collector 1, where impurities are intercepted, and the filtered water enters the waste hopper 10. The multi-layered water filter screen 14 with staggered mesh openings can effectively intercept impurities of different particle sizes, improve the cleanliness of the circulating water, ensure that the spray nozzles of the spray pipe 8 are not easily clogged, maintain the spray dust removal effect, and extend the service life of the equipment.

[0030] Specifically, the output end of the input fan 5 is connected to the internal casing of the dust collector 1, where a filter cartridge 15 is installed. This filter cartridge is used to perform preliminary filtration of large dust particles in the gas input into the dust collector 1. After the dust-laden gas is output from the input fan 5, it first passes through the filter cartridge 15 connected to its output end. Large dust particles are intercepted by the filter cartridge 15. The gas after preliminary filtration then enters the dust collector 1 for spray treatment. The filter cartridge 15 pre-filters large dust particles in the gas, reducing the pressure of subsequent spray dust removal, improving the overall dust removal efficiency, and reducing equipment wear.

[0031] Specifically, both the output fan 4 and the input fan 5 are driven by variable frequency motors. The control device 13 is electrically connected to the variable frequency motor and can adjust the fan speed in real time according to the pressure and gas flow data in the dust collector 1 to achieve energy-saving operation.

[0032] Specifically, a water quality monitoring sensor is installed inside the water tank 6. The water quality monitoring sensor is electrically connected to the control device 13 to monitor the pH, turbidity, and other indicators of the water in the water tank 6 in real time. When the water quality does not meet the standards, the control device 13 issues an alarm and starts the water quality treatment program. The water quality monitoring sensor in the water tank 6 continuously detects the pH, turbidity, and other indicators of the water and transmits the data to the control device 13. When the indicators do not meet the standards, the control device 13 issues an alarm and starts the water quality treatment program, such as adding chemicals to neutralize the pH and starting the filtration device. This ensures the water quality in the water tank 6 in real time, preventing water quality problems from affecting the spray dust removal effect and equipment performance. Timely handling of water quality problems extends the service life of the equipment and reduces failures and maintenance costs caused by water quality.

[0033] Specifically, the circulation pipe 12 is equipped with a flow regulating valve and a filter. The flow regulating valve is used to regulate the flow rate of the circulating water, and the filter uses a high-precision filter screen to filter impurities in the circulating water, preventing impurities from entering the water tank 6 and the spray pipe 8, thus ensuring the cleanliness of the circulating water. During the process of the circulating water pump 11 sending sewage back to the water tank 6, the flow regulating valve on the circulation pipe 12 adjusts the circulating water flow rate according to actual needs. The high-precision filter screen of the filter further filters the circulating water, preventing impurities from entering the water tank 6 and the spray pipe 8. The flow regulating valve enables precise control of the circulating water flow rate to adapt to different dust removal conditions. The filter ensures the cleanliness of the circulating water, prevents nozzle clogging, ensures stable operation of the spray system, and improves dust removal efficiency.

[0034] Specifically, the inner wall of the waste hopper 10 is equipped with an inclined guide plate with an inclination angle of 30°-45°, which can guide dust and sewage to flow smoothly into the circulating water pump 11, preventing waste from accumulating in the waste hopper 10. After the dust and sewage generated by dust removal fall into the waste hopper 10, they are quickly slid into the inlet of the circulating water pump 11 under the guidance of the inclined guide plate with an inclination angle of 30°-45° on the inner wall of the waste hopper 10. This prevents dust and sewage from accumulating in the waste hopper 10, prevents blockage, ensures smooth sewage circulation, reduces the frequency of manual cleaning, and improves the continuity and stability of equipment operation.

[0035] Specifically, the control device 13 includes a PLC controller, a display screen, and operation buttons. The PLC controller is electrically connected to the micro-drive pump 9, the circulating water pump 11, the water quality monitoring sensor, the output fan 4, and the input fan 5. The display screen can show the equipment operating parameters in real time, and the operation buttons are used to manually set and adjust the equipment operating mode. Operators can set the equipment operating mode and parameters through the operation buttons of the control device 13. The PLC controller receives data from the micro-drive pump 9, the circulating water pump 11, the water quality monitoring sensor, the output fan 4, and the input fan 5 in real time and displays the operating parameters on the display screen. The PLC controller automatically adjusts the operating status of each device according to the data, realizing intelligent and automated control of the equipment, facilitating real-time monitoring and adjustment by operators, improving the accuracy and coordination of equipment operation, and ensuring the efficient and stable operation of the dust removal device.

[0036] Specifically, the dust collector housing 1 is also equipped with a temperature sensor and a humidity sensor, both of which are electrically connected to the control device 13. These sensors are used to monitor the temperature and humidity inside the dust collector housing 1 in real time. When the temperature or humidity exceeds the set range, the control device 13 automatically adjusts the equipment operating parameters. The temperature and humidity sensors inside the dust collector housing 1 monitor the internal temperature and humidity data in real time and transmit it to the control device 13. When the temperature or humidity exceeds the set range, the PLC controller of the control device 13 automatically adjusts the equipment operating parameters, such as adjusting the fan speed and spray volume. This creates a suitable operating environment for the dust collector, preventing abnormal temperature and humidity from affecting the dust removal effect and equipment performance. The automatic adjustment function ensures stable operation of the equipment under complex working conditions and extends the equipment's service life.

[0037] The working process of this utility model is as follows: When using this energy-saving wet industrial dust collector, the dust-laden gas first enters the dust collector through the input fan 5. Before entering the dust collector housing 1, it first passes through the filter cartridge 15 installed at the output end of the input fan 5. The filter cartridge 15 intercepts large dust particles in the gas, completing the preliminary filtration process and reducing the burden on subsequent dust removal. The gas that has passed the preliminary filtration enters the dust collector housing 1. Water in the water tank 6 is pressurized and transported to the spray pipe 8 through the water delivery pipe 7 under the action of the micro drive pump 9. The nozzles on the spray pipe 8 atomize the water and spray it out, which then mixes with the dust-laden gas. The gases come into full contact and, through inertial collisions and agglomeration, capture dust particles in the gas, achieving dust removal. The wastewater and dust after dust removal fall into the waste hopper 10 at the bottom of the dust collector 1. During this process, the wastewater first passes through multiple layers of staggered water filters 14 located above the waste hopper 10. The mesh openings of adjacent layers of water filters 14 are staggered, effectively intercepting impurities in the wastewater. Guided by the inclined guide plates (inclination angle 30°-45°) on the inner wall of the waste hopper 10, the filtered wastewater flows smoothly into the circulating water pump 11, and then is transported back to the water tank 6 through the circulation pipe 12. The flow regulating valve on the circulation pipe 12 adjusts the circulating water flow rate. The filter uses a high-precision filter screen to further filter the circulating water, ensuring the cleanliness of the circulating water entering the water tank 6 and achieving water resource recycling. The purified gas after spray dust removal is discharged from the dust collector 1 through the output fan 4.

[0038] The water quality monitoring sensor inside water tank 6 monitors the pH, turbidity, and other indicators of the water in real time and transmits the data to the control device 13. When the water quality does not meet the standards, the control device 13 issues an alarm and starts the water treatment program to ensure that the water quality in water tank 6 meets the requirements for spraying.

[0039] Both the output fan 4 and the input fan 5 are driven by variable frequency motors. The control device 13 is electrically connected to the variable frequency motor. Based on the pressure and gas flow data in the dust collector 1, the fan speed is adjusted in real time to ensure smooth gas discharge and achieve energy-saving operation.

[0040] The control device 13 includes a PLC controller, a display screen, and operation buttons. The PLC controller is electrically connected to the micro-drive pump 9, circulating water pump 11, water quality monitoring sensor, output fan 4, and input fan 5, respectively. Operators can manually set and adjust the equipment operating mode using the operation buttons, and the PLC controller displays the equipment operating parameters in real time on the display screen. Simultaneously, temperature and humidity sensors inside the dust collector chamber 1 monitor the temperature and humidity inside the chamber in real time and transmit the data to the control device 13. When the temperature or humidity exceeds the set range, the control device 13 automatically adjusts the equipment operating parameters to ensure stable operation of the dust collector in a suitable environment.
