Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust control technology, specifically to an intelligent dust removal device. Background Technology
[0002] Dust particles generated during mining operations can easily cause environmental pollution and health hazards. Existing dust removal equipment mostly adopts a multi-stage series structure with fixed parameters, lacking intelligent control and unable to dynamically optimize energy efficiency according to dust load. Electrostatic dust removal units have fixed voltages, which wastes electricity when the dust concentration is low and has insufficient adsorption efficiency when the concentration is high. Wet dust removal systems have fixed water spray volume, which can easily lead to water mist escape or insufficient settling when humidity fluctuates. Utility Model Content
[0003] The purpose of this invention is to solve the problem that existing dust removal equipment lacks intelligent control and cannot dynamically optimize energy efficiency according to dust load. It provides an intelligent dust removal device that can adjust the electrostatic dust removal, wet spraying and demisting processes in conjunction with the feedback of dust concentration and humidity parameters, and automatically enter the energy-saving mode when the load is low.
[0004] To achieve the above objectives, this utility model provides an intelligent dust removal device, including an air inlet and a purified gas outlet. Dust-laden gas passes through a primary filtration unit, an electrostatic dust removal unit, and a wet dust removal unit sequentially from the air inlet before being discharged through the purified gas outlet.
[0005] The air inlet is embedded with a dust concentration sensor and a humidity sensor. The electrostatic dust removal unit includes an electrode plate assembly connected to a voltage regulation module. The voltage is dynamically adjusted according to the dust concentration. The wet dust removal unit includes multiple nozzles. The water inlet pipes of the multiple nozzles are equipped with electric proportional regulating valves. The water spray volume is adjusted according to humidity feedback. The purified gas outlet is equipped with a gas quality monitor to detect the dust concentration at the outlet in real time.
[0006] Preferably, the primary filtration unit includes multiple layers of filter screens, and the pore size of the multiple layers of filter screens gradually decreases along the air outlet direction of the primary filtration unit.
[0007] Preferably, the electrode plate assembly includes multiple positive electrode plates and multiple negative electrode plates, which are arranged alternately.
[0008] Preferably, a demister is provided at the outlet of the wet dust removal unit, and the centrifugal fan speed of the demister is linked to the water spray volume.
[0009] Preferably, the bottom ash discharge ports of the primary filtration unit, the electrostatic dust removal unit, and the wet dust removal unit are connected to a dust collection box.
[0010] By leveraging feedback from both dust concentration and humidity parameters, the electrostatic precipitator, wet spraying, and demisting processes are adjusted in a coordinated manner to improve dust removal efficiency. Under low load conditions, it automatically enters energy-saving mode to reduce overall energy consumption. Attached Figure Description

[0015] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0016] See Figure 1 and Figure 2 As shown, this utility model provides an intelligent dust removal device, including an air inlet 1 and a purified gas outlet 5. Dust-laden gas passes through a primary filtration unit 2, an electrostatic dust removal unit 3, and a wet dust removal unit 4 sequentially from the air inlet 1 before being discharged through the purified gas outlet 5. The chambers of the primary filtration unit 2, the electrostatic dust removal unit 3, and the wet dust removal unit 4 can be separated by a single shell or located in different shells.
[0017] The air inlet 1 has an embedded dust concentration sensor and a humidity sensor. The dust concentration sensor has a measurement range of 0-1000 mg / m³. 3The system features an accuracy of ±1.5%, a capacitive humidity sensor with a range of 0-100%RH and a response time ≤0.5s, and an embedded controller with an ARM Cortex-M7 core. It incorporates a dust concentration-voltage mapping table and a humidity-water spray volume correction algorithm. The electrostatic dust removal unit 3 includes an electrode plate assembly connected to a voltage regulation module, outputting an adjustable DC high voltage of 0-50kV with a response time ≤0.1s. The voltage dynamically adjusts according to dust concentration. The wet dust removal unit 4 includes multiple nozzles 41, each with an electrically operated proportional regulating valve controlling the water flow rate (0-500L / h) with a valve opening accuracy of ±2%. The water spray volume is adjusted based on humidity feedback. A gas quality monitor is installed at the purified gas outlet 5 to detect the dust concentration at the outlet in real time. A data storage unit records historical data (dust concentration, voltage, water spray volume) and fault logs. A touchscreen interface displays the dust concentration curve, voltage value, and water spray volume in real time, supporting remote monitoring.
[0018] A demister 42 is installed at the outlet of the wet dust removal unit 4. The centrifugal fan speed of the demister 42 is linked to the water spray volume to remove water mist from the gas.
[0019] By leveraging feedback from both dust concentration and humidity parameters, the electrostatic precipitator, wet spraying, and demisting processes are adjusted in a coordinated manner to improve dust removal efficiency. Under low load conditions, it automatically enters energy-saving mode to reduce overall energy consumption.
[0020] The primary filtration unit 2 includes multiple layers of filter screens 21, with the pore size of the filter screens 21 gradually decreasing along the air outlet direction of the primary filtration unit 2. The filter screens 21 are made of stainless steel or other metal materials, and initially intercept large dust particles.
[0021] The electrode plate assembly includes multiple positive electrode plates 31 and multiple negative electrode plates 32, which are arranged alternately. The electrode plate spacing is 10-15mm, and the surface is covered with a silicon carbide wear-resistant coating. The electrode plate assembly is connected to a voltage regulation module via a high-voltage cable to apply a high voltage, which charges the dust particles and causes them to be adsorbed onto the multiple positive electrode plates 31 and multiple negative electrode plates 32.
[0022] The bottom ash discharge ports of the primary filter unit 2, the electrostatic precipitator unit 3, and the wet dust collector unit 4 are connected to a dust collection box 6. One dust collection box 6 can be set up, with the primary filter unit 2, the electrostatic precipitator unit 3, and the wet dust collector unit 4 connected to the dust collection box 6 respectively. Alternatively, three dust collection boxes 6 can be set up and connected to the primary filter unit 2, the electrostatic precipitator unit 3, and the wet dust collector unit 4 respectively.
