The present invention provides an ultra-low ozone based electrostatic air purifier with a constant current and a restricted voltage. The air purifier comprises a base plate. Four sides that are perpendicular to the base plate are provided with a front cover, a rear cover, a right-side plate and a left-side plate, and an upper opening defined by the front cover, the rear cover, the right-side plate and the left-side plate is provided with a top cover. An air duct, an exhaust fan, an ozone decomposing and filtering screen, an activated carbon filtering screen and an electrostatic dust removal device are provided in turn in a direction from the rear cover to the front cover. The electrostatic dust removal device comprises a dust collection sheet holder, a first positive electrode high voltage dust collection sheet group, a negative electrode dust collection sheet group, and a second positive electrode high voltage ionizing wire. The first positive electrode high voltage dust collection sheet group and the negative electrode dust collection sheet group are provided on two sides of the dust collection sheet holder. The first positive electrode high voltage dust collection sheet group and the negative electrode dust collection sheet group are stacked in a staggered manner at intervals. The second positive electrode high voltage ionizing wire is provided on a front side of the first positive electrode high voltage dust collection sheet group. A high voltage power supply box supplies power to the first positive electrode high voltage dust collection sheet group and the second positive electrode high voltage ionizing wire. The high voltage power supply box is further capable of maintaining a constant current and voltage restriction, and automatic voltage compensation.
Description
technical field [0001] The invention relates to an air purifier, in particular to a constant-current-limited-voltage ultra-low ozone electrostatic air purifier. Background technique [0002] Severe air pollution has spawned various air purification technologies, including HEPA technology and photocatalyst technology. Considering the high resistance, high energy consumption and expensive cost of regular replacement of consumables of HEPA technology, it has greatly hindered the promotion and application of HEPA technology in air purifiers; photocatalyst technology has better degradation of formaldehyde, benzene, and VOC. However, the timeliness is not good, and it has no purification effect on PM2.5 and other particulate matter that can enter the lungs, so the photocatalyst can only be used as an auxiliary means of air purification; although the traditional electrostatic air purifier has the advantage of not needing to replace consumables, the purification efficiency is not go...
