Abstract

The invention discloses an air purifying device with a hollow fiber membrane. The air purifying device comprises a shell, wherein a first filter cavity, a draught fan cavity and a second filter cavity are formed in the shell; an air inlet which is used for communicating the first filter cavity with external air is formed in the shell; the first filter cavity is internally provided with a hollow fiber membrane filter assembly which is used for filtering air entering the first filter cavity from the air inlet; the draught fan cavity is internally provided with a draught fan which is used for sucking the air filtered by the hollow fiber membrane filter assembly in the draught fan cavity; an air inlet of the draught fan is connected with an air generation opening of an end cover, and an air outlet is located in the draught fan cavity; a communicating opening which is used for enabling the air in the draught fan cavity to enter the second filter cavity is formed between the draught fan cavity and the second filter cavity; the second filter cavity is internally provided with an activated carbon filter assembly which is used for filtering the air entering the second filter cavity. According to the air purifying device with the hollow fiber membrane, disclosed by the invention, clean oxygen-containing fresh air can be supplied to a room, and the room is kept in low carbon dioxide concentration, so that people in a relatively-closed environment can feel fresh and natural indoor air.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a hollow fiber membrane air purification device. Background technique [0002] In recent years, people pay more and more attention to indoor air quality. Hollow fiber membrane air purification device can filter outdoor dirty air through PTFE hollow fiber membrane. However, since the PTFE hollow fiber membrane mainly filters some dust particles, the effect on toxic and harmful gases is not obvious enough. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hollow fiber membrane air purification device, which can strengthen the air purification effect and improve the filtering ability of toxic and harmful gases. [0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: a hollow fiber membrane air purification device, including a housing, the inside of ...
