Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of new trend system for building, more specifically to a kind of high efficiency low resistance matrix active static electricity auxiliary new fan filter section for building. BACKGROUND

[0002] Particulate matter (PM) and pathogenic microorganisms suspended in the air are the main sources of indoor air pollution, which can induce complex diseases such as respiratory system, cardiovascular system and reproductive system. Modern people spend about 80% to 90% of their time in indoor environment, so the demand for indoor air purification has also increased significantly. As an important equipment for improving indoor air quality and promoting air circulation and introducing external fresh air, the new trend system for building has been widely used in recent years, and its filtering capacity is gradually improving.

[0003] However, the existing fresh air system has good filtering efficiency during use, but generally has the problems of large filtering resistance and insufficient dust holding capacity. At present, the filtering methods of the fresh air system for buildings are mainly divided into three types. The first type is a non-woven fabric structure filtering system: the non-woven fabric structure filtering system generally uses non-woven fabric materials with different tightness and thickness as filter materials, which are divided into primary, medium and high efficiency filter materials and can be used in combination. When configured, they are arranged in sequence along the air flow direction. The primary and medium efficiency filter screens have good filtering effect on medium and large particles, and the high efficiency filter screen has good filtering effect on small particles. The non-woven filter material structure is dense and has small pores, although the filtering efficiency is high, but the filter resistance is large, the filter screen has limited dust holding capacity, needs to be replaced frequently, has high energy consumption and cost, and a large amount of waste filter material will also cause environmental pollution. The non-woven filter material only intercepts the pathogenic microorganisms, does not kill them, and the pathogenic microorganisms are easy to attach and reproduce on the filter material, release odor, and cause secondary pollution after desorption. The bacteria killing is usually realized by configuring ultraviolet lamps, but the ultraviolet lamps and interfaces are easy to break, and the radiation is easy to cause aging of the filter material and surrounding parts; the second type is a static electric field filtering system. In order to enhance the filtering efficiency of the filter material and reduce the filter resistance, the static electric field technology can be used to make the non-woven or sponge structure filter material load space charge and dipole charge. In addition to the general mechanical filtering effect, the Coulomb force generated by the electric charge can realize the capture of dust, greatly improve the capture effect of small particles, and also realize the capture, inhibition and killing effect of microorganisms. Compared with the high efficiency filter screen, the filtering efficiency is improved, the filter resistance is small, and the dust holding capacity is slightly increased. However, the filter screen has the problems of storage charge consumption and escape, the filtering efficiency will decrease with time, the filter material replacement cycle is increased, or the charging module is increased, but the complexity of the equipment and the maintenance cost are also increased. It is generally used together with the non-woven fabric structure filtering system; the third type is an electrostatic precipitator (ESP) or negative ion filtering system. The electrostatic precipitator ionizes the gas to generate positive and negative ions, and the dust captures the negative ions and migrates to the electrode plate under the action of the electric field force. It has good removal efficiency for large particles or high concentration dust, and small resistance. However, the removal efficiency for small particles is low, and the filtering efficiency is greatly affected by environmental factors such as humidity. The ion generating part is made of relatively fragile tungsten wire, has short service life and is difficult to clean. It is often used together with the non-woven fabric structure filtering system. Negative ion dust removal uses the adsorption and sedimentation effect of negative ions released by the sharp tip on particulate matter to purify air, can avoid the use of tungsten wire structure, can be used alone for air purification, and can also be used with traditional filter screens to improve filtering efficiency. However, the current negative ion generating device has low ion concentration and limited range of action.
