Problems solved by technology

The activated carbon adsorption method tends to lose its adsorption performance as the adsorption reaches saturation, and the activated carbon is low in strength and fragile, which is easy to cause secondary pollution. Photocatalytic oxidation can effectively decompose indoor VOC, but its decomposition products cannot be controlled, causing more serious pollution

Abstract

The invention relates to an aldehyde removal air purifier based on thermal catalytic oxidation. An air inlet duct and a thermal catalytic oxidation aldehyde removal duct are arranged between an air inlet and an air outlet; a first air inlet and a second air inlet are arranged in the bottom of the air inlet duct, and a conversion valve is arranged between the first air inlet and the second air inlet; a copper tube is arranged in the thermal catalytic oxidation aldehyde removal duct, and a granulated nano-manganese dioxide catalyst is attached to the outer surface of the copper tube; one end ofthe copper tube is connected with a solar vacuum tube, the other end of the copper tube is connected with a water box through a water outlet pipeline, and the water box is connected with the solar vacuum tube through a circulating water pump; a solar concentrator is arranged on the lower portion of the solar vacuum tube, and the solar vacuum tube is located at the parabolic focus of the solar concentrator. By rotating the conversion valve, the air is introduced from indoors or outdoors, formaldehyde concentration of an enclosed room can be reduced, and the aldelyde removal air purifier can beused as a fresh air system.

Description

technical field [0001] The invention relates to an air purifier, in particular to an aldehyde-removing air purifier based on a thermal catalytic oxidation method. Background technique [0002] People spend 70%-90% of their time indoors in their lives, and the quality of indoor air is closely related to people's health. At present, with the rapid increase in the number of newly built and renovated houses in cities in our country, the resulting indoor pollution has had a huge impact on human health. Formaldehyde, benzene, xylene and other pollutants are commonly found indoors in residential buildings in my country. Formaldehyde is the primary pollutant and has the characteristics of a wide range of sources, a large concentration range, and a long release cycle. At present, the removal methods of indoor formaldehyde in the market mainly adopt methods such as activated carbon adsorption, photocatalytic oxidation and thermal catalytic oxidation. The activated carbon adsorption ...
