Abstract

The invention discloses a perforated plate fresh air introducing and purifying device and belongs to the technical field of air energy recycling and high efficiency energy saving in ventilation equipment. The device comprises a perforated plate purifying, energy recycling and heating core, a fresh air machine, an exhaust fan and an electric cabinet, wherein the size of the perforated plate purifying, energy recycling and heating core is 160mm*160mm to 350mm*350mm; the perforated plate purifying, energy recycling and heating core comprises 45 to 2400 pieces of perforated plate semi-closed conductive combinations and corrugated pieces; each perforated plate semi-closed conductive combination comprises a perforated plate, conductive bands, purifying copper sheets A and B, and heating copper sheets A and B; a square hole shaped fresh air channel with the side length being 1 to 20mm is formed in the perforated plate; the conductive bands are printed or sprayed on the two outer surfaces of the perforated plate; the purifying copper sheets A and B and the heating copper sheets A and B are respectively adhered to the two ends of the conductive bands on the two outer surfaces of the perforated plate; the perforated plate semi-closed conductive combinations and the corrugated pieces form 90 degrees and are assembled alternately and crosswise. The perforated plate fresh air introducing and purifying device has the benefits that new pollutant, such as ozone and the like, is not produced, energy can be efficiently recycled, condensation cannot be produced when the device is used in cold regions, and meanwhile the purification efficiency is high.

Description

technical field [0001] The invention relates to a fresh air introduction device, in particular to an orifice-type fresh air introduction and purification device, which belongs to the technical field of air energy recovery, high efficiency and energy saving in ventilation equipment. Background technique [0002] With the exposure of PM2.5 and severe indoor air pollution, the airtightness of buildings and the improvement of thermal insulation performance. The state attaches great importance to the control of indoor air pollution and the energy saving of buildings and indoor ventilation. pollution control. [0003] The main source of PM2.5 is outdoors. Because its particles are small and pervasive, according to the monitoring situation in Beijing from July to August 2013, the pollution level of PM2.5 indoors tends to exceed that of outdoors. Since indoors are the main activities and living places of human beings, the pollution of PM2.5 to indoors has reached a very serious le...
