Abstract

The invention relates to an electro-catalytic air purifier and an air purification method of the electro-catalytic air purifier. The first aim of the invention is to provide an electro-catalytic air purifier, which is small and exquisite in structure, low in electricity consumption, quick in formaldehyde removal and environment-friendly. The second aim of the invention is to provide an electro-catalytic air purification method aiming at the air purifier. The first aim of the invention is achieved by the following technical scheme: the electro-catalytic air purifier comprises a shell, an electrolyte circulating pump, as well as an air suction fan, a spraying head, a plurality of three-dimensional electrode reactors and a liquid storage tank which are arranged in the shell sequentially from top to bottom. The second aim of the invention is achieved by the following technical scheme: the electro-catalytic air purification method comprises the following steps: (1) dissolving formaldehyde into Na2SO4-Na2CO3 mixed electrolyte by using the air suction fan and the electrolyte spraying head; (2) enabling the electrolyte in the step (1), into which the formaldehyde is dissolved, to vertically flow into the three-dimensional electrode reactors; and (3) introducing direct current into the three-dimensional electrode reactors so as to oxidize the formaldehyde into sodium formate.

Description

technical field [0001] The invention relates to an electrocatalytic air purifier and a method for purifying air. Background technique [0002] Formaldehyde is currently the largest source of pollution in the living room. Formaldehyde (molecular formula: HCHO), also known as formic aldehyde, is the simplest form of aldehyde and is usually a flammable, colorless and irritating gas. Soluble in water, alcohol and ether. Formaldehyde is a highly toxic substance, and formaldehyde ranks second on the list of toxic chemicals controlled in my country. Formaldehyde is defined as carcinogenic and teratogenic shape material by the World Health Organization, is the allergen of generally acknowledging, also is one of potential strong mutagen. Long-term exposure to low-dose formaldehyde can cause chronic respiratory diseases, nasopharyngeal cancer, colon cancer, brain tumors, menstrual disorders, gene mutations in the nucleus, DNA single-strand cross-linking and DNA-protein cross-linkin...
