Air purifier for filtering out respirable particulate matters

Abstract

The invention provides an air purifier for filtering out respirable particulate matters. The air purifier comprises a coarse filtering device and a DEP purifying treatment unit, wherein a flow equalizing plate is arranged between the outlet of the coarse filtering device and the DEP purifying treatment unit, so as to enable air to uniformly flow into the DEP purifying treatment unit, the DEP purifying treatment unit comprises M DEP purifying electrode plates, the arrangement direction of the M DEP purifying electrode plates is parallel or approximately parallel to gas inlet direction, and the DEP purifying electrode plates are flat plates or arc-shaped plates or of shapes formed by connecting a limited number of flat plates and / or arc-shaped plates. According to the air purifier, the coarse filtering device is adopted to filter relatively large dust particles, so as to play a role in protecting the DEP purifying treatment unit; in addition, due to the adoption of the flow equalizing plate, the air passing through the central part of the flow equalizing plate undergoes high resistance, the air passing through the peripheral part of the flow equalizing plate undergoes low resistance, and then, the density of the air is regulated, so that automobile exhaust gas gently and uniformly flows through a purification system, and thus, the purification efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of material purification treatment, in particular to an air purifier for filtering particulate matter that can enter the lungs. Background technique [0002] With the development of society and economy, on the one hand, the consumption of fossil energy and the discharge of pollutants are constantly increasing. On the other hand, in order to live a more comfortable and healthy life, people have higher and higher requirements for environmental cleanliness. In order to deal with the environmental problems caused by high pollution, the country has put forward more and more strict requirements on the concentration of pollutants discharged into the air, water and soil. In order to achieve a lower concentration of emissions, companies need dust removal equipment with better performance. At present, there are many kinds of dust removal equipment for dust particles in the air, including mechanical dust collectors, e...

Problems solved by technology

However, the above-mentioned dust collectors are mainly used to deal with larger dust in the air. For the particles that can enter the lungs, the existing dust removal equipment is not effective in dust removal. The use of such dust removal equipment has buried hidden dangers for the health and safety of the public.

[0003] In addition, when the air flow is flowing, there is a phenomenon of uneven flow in the plane perpendicular to the flow velocity direction. Therefore, it is necessary to design the inlet of the purifier so that the air flow flows through the purifier smoothly and evenly to improve the purification efficiency.
