Example Embodiment
[0044] Example 1
[0045] Adopt the indoor air circulation purifier of the present invention in 30m 3 The performance test is carried out in the standard test chamber. In this embodiment, the indoor air circulation purifier has two airflow channels (only one of the airflow channels is opened in the test), and the cross-sectional area of each airflow channel is 0.08m 2 , the photocatalytic unit is arranged in a V shape (oblique air intake), the angle between the photocatalytic unit and the horizontal direction is 64°, and the air passage area of the photocatalytic unit is 0.18m 2 , the air volume of the axial fan is 1350m 3 / h. The initial formaldehyde concentration is 1.11ppm, and the air exchange volume is 975m 3 / h, the filtration efficiency of formaldehyde reached 92.9% after running for 1 hour.

Abstract
The invention discloses a circulation purifier for indoor air. The circulation purifier comprises a shell, filter screens and photocatalysis filter layers. Two or more airflow channels are formed between an air inlet and an air outlet; the filter screens are horizontally arranged in the airflow channels; the photocatalysis filter layers are arranged on the downstream portions of the filter screensand detachably and hermetically connected into the airflow channels, each photocatalysis filter layer is composed of multiple photocatalysis units which are arrayed in a broken line, and each photocatalysis unit comprises a catalysis plate, two grilling lamp panels and an axial flow fan; the catalysis plates are foam ceramic plates loaded with photocatalytic active components; every two grillinglamp panels are parallelly arranged at the two sides of each catalysis plate respectively, and multiple ultraviolet LED light sources are evenly distributed on grid bars of the grilling lamp panels. According to the circulation purifier for the indoor air, through the broken line array of the photocatalysis units, the air passing area of the unit cross section is increased, the wind resistance islowered, and the filtering efficiency is improved; the photocatalysis units are obliquely arranged, inflow airflow can form vortexes at openings of the foam ceramic plates, and contact of gas and a catalyst is enhanced.
Description
technical field [0001] The invention relates to the field of industrial waste gas purification, in particular to an indoor air circulation purifier. Background technique [0002] When the concentration of volatile organic compounds (VOCs) in indoor air is too high, it is easy to cause acute poisoning. In mild cases, headache, dizziness, cough, nausea, vomiting or intoxication may occur; in severe cases, liver poisoning or even coma will occur soon. Some may even be life-threatening. Living or working indoors polluted by VOCs for a long time can cause chronic poisoning, damage the liver and nervous system, cause general weakness, drowsiness, itchy skin, etc. Benzene and xylene may also damage the system and even cause leukemia. However, VOCs pollution in existing workshops is generally discharged through ventilation, and is only processed and detected at the end of the air exhaust, lacking indoor environmental detection and processing methods. The construction cost of the a...
