Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to an integrated photocatalytic adsorption purification unit. Background Art

[0002] As people's requirements for environmental quality increase, air purification units have become an indispensable part of people's lives and work. There are many kinds of air purification units on the market, such as air purification units mainly prepared by photocatalytic modules, which are mainly used to purify acetylene and other hydrocarbon gases in the air, and air purification units mainly prepared by activated carbon adsorption modules, which are mainly used to remove odors in cold storage. The activated carbon filter bed serves as the damping layer of the air purification unit, which can reduce noise and stabilize the airflow. In the existing independent photocatalytic modules, part of the airflow will flow out directly through the gap between adjacent ultraviolet lamps, and the purification effect is poor; the existing independent activated carbon adsorption modules generally load the adsorption material directly into the cloth bag, which has large airflow resistance and uneven purification, and the purification effect is poor. In addition, most of the frames used are formed by bending and welding, such as Figure 1 As shown, the process is complicated and prone to distortion and deformation, which is not only time-consuming and labor-intensive, but also prone to leakage of adsorption materials. At the same time, most of the existing air purification units are independent photocatalytic modules or independent activated carbon adsorption modules, and the adsorption effect is poor.
