Abstract

The formaldehyde purification device comprises an air inlet and an air outlet, an air extractor, a formaldehyde adsorption part, a first detection sensor and a second detection sensor are sequentially communicated between the air inlet and the air outlet through an airflow pipeline, the first detection sensor and the second detection sensor are arranged at the two ends of the formaldehyde adsorption part respectively, and meanwhile a backflow part is further arranged. The formaldehyde adsorption part is used for controlling circulating adsorption of air which does not reach the standard and comprises an adsorption tower and a formaldehyde adsorption layer, the two ends of the adsorption tower are communicated with airflow pipelines respectively, and the adsorption tower is filled with the formaldehyde adsorption layer. According to the formaldehyde purification device, air which does not meet the set purification effect can be purified again through the backflow pipeline, it is ensured that the concentration of formaldehyde exhausted into the air reaches the standard, and the air purification effect can be further ensured through arrangement of the spoiler and dual adsorption of the potassium permanganate adsorption layer matched with the activated carbon adsorption layer.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a formaldehyde purification device. Background technique [0002] Indoor air pollution includes chemical pollution, biological pollution and physical pollution. Among them, chemical pollution refers to the pollution caused by chemical substances, such as formaldehyde, benzene series, ammonia, ammonia and its daughters and suspended particles. Formaldehyde, a colorless and irritating gas, has become one of the main indoor pollutants due to its wide source, high toxicity and long pollution time. It not only affects the upper respiratory tract and lungs of the human body, stimulates allergies, causes liver function, immune function, and nervous system abnormalities, resulting in partial loss of central function, and long-term exposure to high-quality formaldehyde can lead to the occurrence of various cancers. Formaldehyde-based pollutants pose a serious threat to human he...
