A high-efficiency and energy-saving air purification device capable of removing fine particles

Abstract

The invention discloses an efficient energy-saving air purifying device capable of removing fine particulate matter. The efficient energy-saving air purifying device comprises an air inlet section, a rough-acting filter section, an intermediate-acting filter section, a PM2.5 purification function section capable of being opened and closed, a draught fan section, a cooling section / heater section, a reheating section, a humidifying section and an air outlet section which are sequentially distributed, wherein the PM2.5 purification function section capable of being opened and closed comprises a frame body, a high-intermediate-acting or second-high-acting air filter and a rotating shaft; the frame body comprises a perpendicular square frame, a high-intermediate-acting or second-high-acting air filter supporting frame and a high-intermediate-acting or second-high-acting air filter fixing frame. According to the efficient energy-saving air purifying device, work modes can be switched manually or automatically according to the PM2.5 concentration of indoor air and the PM2.5 concentration of outdoor air, and under the precondition that the PM2.5 pollutant concentration of the indoor air is effectively controlled, energy-saving operation of a draught fan system and long-service-life operation of the high-intermediate-acting or second-high-acting air filter are achieved. The efficient energy-saving air purifying device has the advantages of being multiple in function, saving energy, being environmentally friendly, safe, and convenient to use and the like, and can be suitable for central air-conditioning systems of civil architectures.

Description

technical field [0001] The invention relates to a high-efficiency and energy-saving air purification device, which belongs to the field of building indoor environment air purification, and in particular relates to a high-efficiency and energy-saving air purification device capable of removing fine particles. Background technique [0002] According to the latest statistics released by the Ministry of Environmental Protection on its website, in the first half of this year, the number of days with substandard air quality in 74 cities including the Beijing-Tianjin-Hebei region, the Yangtze River Delta region, the Pearl River Delta region, municipalities directly under the central government, provincial capitals, and cities specifically designated in the state plan accounted for almost half of the total. , and the pollution in the Beijing-Tianjin-Hebei region is the most serious, with 26% of days being "heavily polluted", and the culprit is fine particulate matter PM2.5. Usually,...

Problems solved by technology

However, due to the higher filtration efficiency of the air filter, the air resistance of the unit increases accordingly, resulting in a decrease in the air handling capacity of the air handling unit and an increase in energy consumption of the unit

Obviously, when the outdoor and indoor air quality is good, keeping the high-efficiency or sub-high-efficiency air filter in working condition for a long time is not conducive to the energy saving of the air-conditioning fresh air system, but also causes unnecessary waste of operating costs and resources
