Abstract

The invention discloses a circulating air suction and release type indoor formaldehyde removal device and a use method, and belongs to the technical field of air purification. According to the scheme,a vertical pulling rod is pulled downwards, on one hand, a movable round plug plate can be driven to move downwards, and therefore air on the lower side of the movable round plug plate is extruded outwards; a formaldehyde purification adsorbent in a side ventilation filter bag sleeve is dispersed by means of air flow, the possibility of mutual agglomeration of the formaldehyde purification adsorbent is reduced, and therefore the formaldehyde absorption efficiency of the formaldehyde purification adsorbent is improved; on the other hand, an elastic connecting rope in a built-in storage box canbe pulled downwards, effervescent powder in the elastic connecting rope is enabled to fall into a water solution, carbon dioxide gas can be generated, and the movable round plug plate is pushed to continue to move downwards; and meanwhile, by means of a generated chlorine dioxide solution, formaldehyde entering from a second gas path one-way valve can be absorbed, carbon dioxide and water are continuously generated, and therefore indoor formaldehyde is continuously absorbed.

Description

technical field

[0001] The invention relates to the technical field of air purification, and more specifically, relates to a circulation suction and discharge type indoor formaldehyde removal device and a use method thereof. Background technique

[0002] Formaldehyde, colorless and irritating gas, chemical formula HCHO or CH 2 O, molecular weight 30.03, also known as formaldehyde. Irritant to human eyes and nose. The relative density of gas is 1.067 (air=1), and the density of liquid is 0.815g / cm 3 (-20°C). Melting point -92°C, boiling point -19.5°C. Soluble in water and ethanol. The concentration of the aqueous solution can reach up to 55%, generally 35%-40%, usually 37%. It is called formaldehyde water, commonly known as formalin (formalin). powerful. Can burn, steam and air form explosive mixture, explosion limit 7%-73% (volume), ignition point is about 300 ℃, can be produced by dehydrogenation or oxidation of methanol under the catalysis of silver, copper and othe...
