Description

Technical Field

[0001] The utility model relates to the field of static electricity removal and dust removal, in particular to a bag dust collector with static electricity removal function. Background Art

[0002] The working principle of the electrostatic precipitator is to use a high-voltage electric field to ionize the flue gas, and the dust in the airflow is charged and separated from the airflow under the action of the electric field. The negative electrode is made of metal wires with different cross-sectional shapes, which is called the discharge electrode. The positive electrode is made of metal plates with different geometric shapes, which is called the dust collecting electrode. The performance of the electrostatic precipitator is affected by three factors: the nature of the dust, the structure of the equipment, and the flow rate of the flue gas. The resistivity of the dust is an indicator for evaluating the conductivity, which has a direct impact on the dust removal efficiency. If the resistivity is too low, it is difficult for the dust particles to remain on the dust collecting electrode, causing them to return to the airflow. If the resistivity is too high, the charge of the dust particles reaching the dust collecting electrode is not easy to be released, and the voltage gradient formed between the dust layers will cause local breakdown and discharge. These situations will cause the dust removal efficiency to decrease.

[0003] With the improvement of the quality of life, more and more people begin to pay attention to their physical health. The dust in the air can cause great harm to our lungs. At the same time, various static electricity phenomena will occur in winter. However, when the existing electrostatic precipitator is dumped, the collected dust will be scattered back into the air to form secondary dust. At the same time, it is difficult to meet the needs of some special groups of people for some moist air. Utility Model Content
