Integrated composite air purifier and air purification method

Abstract

The invention belongs to the technical field of indoor air purification, and specifically relates to an integrated composite air purifier. The integrated composite air purifier comprises a shell, a perforated air outlet plate, an air inlet mechanism and a purification mechanism; the air inlet mechanism comprises a fan casing and an eddy fan; the purification mechanism comprises an active carbon retainer, an airflow sealing plate, an upper active carbon fixed plate and a discharge dust collection module; and the discharge dust collection module comprises an active carbon pole plate and a discharge pole plate. The invention further relates to an air purification method, comprising the steps of corona discharge and air ionization, ionization degradation of particulate matter charges and VOCs gas molecules, charged particulate matter deposition and VOCs oxidative degradation. An electrostatic dust collection technology, a radial-flow active carbon dust collection electrode, an active carbon adsorption technology and an ozone catalytic oxidation technology are integrated into a separate process, and the adsorbed VOCs are continuously degraded by using ozone, so that the active carbon in the purifier can keep efficient adsorption performance for VOCs for a long term, secondary pollutants caused by ozone are avoided, and pollutants are really transformed from traditional collection to purification degradation.

Description

technical field [0001] The invention belongs to the technical field of indoor air purification, and in particular relates to an integrated composite air cleaner and an air purification method. Background technique [0002] With the deterioration of air quality, the phenomenon of smog weather has increased, which directly endangers people's health. In the northern part of our country, the smog weather is becoming more and more serious. How to ensure that people can live in an environment with better air quality is an important problem that needs to be solved urgently. As a device for purifying the air, air purifiers are becoming more and more popular. [0003] Traditional air purifiers are generally divided into two categories. One is the air purifier with filtration and adsorption as the main treatment technology. In terms of particle purification, it is mainly realized by HEPA filter. Replacement; in the purification of gaseous pollutants, activated carbon adsorption is c...

AI Technical Summary

Problems solved by technology

Electrostatic dust removal technology generally has the problem of ozone secondary pollution. Although some purifiers use positive high-voltage discharge to reduce the generation of ozone, it is still difficult to completely eliminate the impact of ozone on the indoor environment. The dust accumulation area is small, and the dust accumulation will affect the electrostatic precipitator effect, and the dust collecting plate needs to be cleaned regularly

The air purification technology uses activated carbon as the VOCs adsorbent. The removal of gaseous pollutants mainly depends on the adsorption performance of activated carbon. After a certain amount of VOCs is adsorbed by activated carbon, its adsorption performance will decrease. In general, there is no big difference in the adsorption performance of activated carbon in the reverse release of gaseous pollutants. Due to the limited amount of activated carbon in the purifier, it is necessary to replace the filter membrane, filter screen and activated carbon several times during the entire life cycle of the purifier. , which puts higher requirements on the structure of the whole equipment, and increases the risk of damage to the purifier and the long-term use cost
