A high-efficiency through-wall fresh air purification device

Abstract

The invention discloses an efficient wall-penetrating-type fresh air purifying device, and belongs to the technical field of fresh air purifying. The efficient wall-penetrating-type fresh air purifying device comprises an indoor face plate, a wall penetrating body, an inner barrel, an outer barrel and an outdoor air-inlet rain cover. The outer barrel is in sliding fit with the inner barrel, and the outer side of the outer barrel is in close fit with the inner wall of a wall hole. An HEPA filter, a low efficiency filter and a full-plastic-packaging axial flow fan are arranged in the wall penetrating body. The HEPA filter is an HEPA folded conical core filter. The HEPA folded conical core filter comprises an HEPA folded filtering conical core, a top positioning disc and a bottom air stopping disc. The HEPA folded filtering conical core is connected with the bottom air stopping disc through hot melt adhesive and connected with the top positioning disc through hot melt adhesive. The diameter of the top of the HEPA folded filtering conical core ranges from 100 mm to 500 mm, the diameter of the bottom of the HEPA folded filtering conical core ranges from 30 mm to 400 mm, and the height of the HEPA folded filtering conical core ranges from 100 mm to 300 mm. A circular air hole is formed in the middle of the top positioning disc, and the diameter of the circular air hole ranges from 70 mm to 470 mm. The efficient wall-penetrating-type fresh air purifying device has the beneficial effects of being low in density, small in air resistance, large in air volume, long in service life, low in cost and ideal in dust removal effect.

Description

technical field [0001] The invention relates to a wall-through fresh air purification device, in particular to a high-efficiency wall-through fresh air purification device, which belongs to the technical field of fresh air purification. Background technique [0002] With PM2.5 exposure and serious indoor air pollution. The country attaches great importance to the control of indoor air pollution, and has issued a series of national standards, requiring fresh air to be introduced into civil buildings and control of indoor air pollution. 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 level. Degradation of indoor particle pollution has become a top priority in Chin...
