Electrostatic field adsorption device with single-pole matrix type discharge structures

Abstract

The invention designs an electrostatic field adsorption device with a unipolar matrix discharge structure, which includes several negative plates placed in parallel, and is characterized in that: each negative plate corresponds to a positive plate, and the positive plate and the negative plate are located on the same horizontal plane , there is a gap between the positive plate and the negative plate. Several discharge needles are arranged on the end face of the positive plate facing the negative plate. The discharge needles on all positive plates are parallel to each other. The gap width between the positive plate and the negative plate is 3-40mm. The advantage of the present invention is that the positive and negative plate modules are composed of independent structures, which can completely get rid of the insulation trouble of cross-connection, and the ventilation airflow and the charge movement direction are on the same plane to maintain direct docking, and the adsorption force is greatly increased. Under the condition of equal electric field section size, The number of positive and negative plates can be doubled, thereby doubling the charge release and dust collection capacity of the electrostatic field per unit volume.

Description

technical field [0001] The invention relates to an electrostatic field adsorption device with a unipolar matrix discharge structure. Background technique [0002] The traditional electrostatic field used in the field of air purification has a common feature, that is, high pressure and high adsorption, low pressure and low adsorption, while high pressure and high ozone, low pressure and low ozone. Before the critical technology of ozone generation is not fully grasped, this state cannot be solved for a long time, so the electrostatic devices with a voltage higher than 4000V are the first to be eliminated, and there are only a very small number of voltages not higher than 4000V to ensure that the ozone does not exceed the standard. The electrostatic device designed through the technical approach of improving the adsorption efficiency has found a road to application in theory. For example, the three-stage sub-high voltage electrostatic field and the bipolar two-stage pulse sub...

Problems solved by technology

However, the common feature of these four generations is that the electric field structure belongs to the vertical cross mode. The inherent disadvantage of this mode is that in order to ensure the strict insulation requirements between the positive and negative electrodes of the cross installation, it brings great technical difficulties to the structural design. At the same time, the direction of charge movement in the electric field is perpendicular to the direction of ventilation, which reduces the coefficient of adsorption efficiency, and the complex structure makes production and maintenance more difficult.
