Indoor air quality monitoring and purifying system

Abstract

The invention relates to the technical field of air purification, and discloses an indoor air quality monitoring and purifying system which comprises a mixing chamber and a water tank. A capillary water absorption column is arranged in the water tank, an ultrasonic atomizer is arranged on the side wall of the water tank, and the capillary water absorption column is connected with the water inlet end of the ultrasonic atomizer; a guide pipe is arranged on the side wall of the mixing chamber, and a needle-shaped electrode is arranged in an inner cavity of the guide pipe; an electrode plate is arranged on the outer wall of the mixing chamber, and the needle-shaped electrode and the electrode plate are electrically connected with positive and negative electrodes of a high-voltage power supply;an air inlet pipe with an exhaust fan and an air monitor is arranged at the bottom of the mixing chamber; and an exhaust pipe with an air-mist separation mechanism is arranged on a top cover of the mixing chamber. According to the indoor air quality monitoring and purifying system, water mist is generated through ultrasonic atomization, an electric field is applied to the water mist to enable thewater mist to be electrified, the water mist is rapidly and efficiently mixed with air entering the mixing chamber, finally, clean air is obtained through separation of the air-mist separation mechanism, and the purification efficiency is high; and the charged water mist has a certain killing effect on microorganisms carried on particles or suspended matters.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an indoor air quality monitoring and purification system. Background technique [0002] At present, most of the human activity space is indoors, so the indoor air quality greatly affects people's health. With the rapid construction of urbanization, the harm of indoor dust pollution to the human body is increasing. The dust pollutants in indoor air include dust particles and other suspended solids; especially the particles with a diameter of less than or equal to 2.5 microns, also known as dust particles. Inhaled lung particulate matter (PM2.5), the diameter is less than 1 / 20 of the hair, compared with the coarser atmospheric particulate matter, PM2.5 has a small particle size, a large area, strong activity, and is prone to toxic and harmful substances (such as , heavy metals, microorganisms, etc.), and the residence time in the atmosphere is long, so it has a great impa...
