Fresh air ventilator with electrostatic dust collection device and electrostatic dust collection device for fresh air ventilator

Abstract

The invention discloses a fresh air ventilator with an electrostatic dust collection device. The fresh air ventilator comprises a shell, wherein an air inlet and an air outlet are formed in the shell; a centrifugal fan is arranged in the shell corresponding to the air outlet, and an electrostatic dust collection device is arranged in the shell corresponding to the air inlet; the electrostatic dust collection device comprises a top plate, a bottom plate and two side plates arranged between the top plate and the bottom plate; positive plates and negative plates are arranged between the two side plates; the positive plates and the negative plates are alternately arranged at intervals, and a channel is reserved between every two adjacent plates; and the length direction of the side plates is perpendicular to the air inlet direction of the fresh air ventilator. According to the fresh air ventilator, the air inlet direction of the electrostatic dust collection device in the fresh air ventilator is perpendicular to the air inlet direction of the fresh air ventilator, that is, fresh air enters from the side portion of the electrostatic dust collection device for dust collection and filtration, the magnetic field area is large, the purification efficiency is high, and the size of the needed fresh air ventilator is small. Correspondingly, the invention further provides an electrostatic dust collection device for the fresh air ventilator.

Description

technical field [0001] The invention relates to the field of fresh air fans, in particular to a fresh air fan with an electrostatic dust collection device and an electrostatic dust collection device for the fresh air fan. Background technique [0002] In recent years, with the continuous development of the economy and the continuous improvement of people's living standards, the problem of air quality has attracted people's attention. In order to resist the hazards of smog and maintain their health, people have higher and higher requirements for indoor air quality. The fresh air fan is an effective air purification equipment that can circulate the indoor air. On the one hand, it discharges the indoor dirty air to the outside, and on the other hand, the fresh outdoor air is sterilized, disinfected, filtered and other measures, and then input into the room. Realize indoor air replacement, effectively improve the indoor air quality, and make the room full of fresh air all the ti...

Problems solved by technology

When the fresh air fan is used for a period of time, a certain amount of dust will accumulate on the support plate, causing the support plate to generate charges; at this time, an electric field will be formed between the support plate and the aluminum plate, which may short-circuit and cause sparks, which is more dangerous during use; and now Some electrostatic dust collection devices are mostly fixed and not easy to disassemble. When the dust accumulates a lot, it is difficult to clean, so it is necessary to replace a new electrostatic dust collection device, and the use cos
