A formaldehyde removal device for indoor decoration

Abstract

The invention discloses a formaldehyde removal device for indoor decoration, which belongs to the field of indoor formaldehyde treatment. It is a formaldehyde removal device for indoor decoration. Through the setting of the device, the pull ring can be pulled downward and the bottom plate can be pushed upward, so that the whole bag body The inward bending deformation and compression will cause the horizontal pull rope to tilt downward. With the function of self-tilting flipping of the fish bone, it can move downward and tilt to the middle, which can flip the formaldehyde adsorbent particles in a wider range. Make it loose, and then realize that the formaldehyde adsorbent particles located inside and outside can change in a certain position, thereby increasing the gap between the formaldehyde adsorbent particles, improving the adsorption efficiency of indoor formaldehyde, and when the bag is deformed, it will automatically The role of the dredging brush ring can dredge the curved transparent ring, thereby effectively improving the permeability of the curved transparent ring, thereby effectively ensuring the continuous adsorption of indoor formaldehyde by the device.

Description

technical field [0001] The invention relates to the field of indoor formaldehyde treatment, and more specifically relates to a formaldehyde removal device for indoor decoration. Background technique [0002] Formaldehyde, colorless and irritating gas, chemical formula HCHO or CH 2 O, molecular weight 30.00, also known as formaldehyde. Colorless, irritating 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%, usually 40%, which is called formaldehyde water, commonly known as formalin (formalin). Reducing, especially in alkaline solution, the reducing ability is stronger. Can burn, vapor and air form explosive mixture, explosion limit 7%-73% (volume). The ignition point is about 300°C. It can be produced by the dehydrogenation or oxidation of methanol under the cataly...

Problems solved by technology

[0004] During interior decoration, due to the use of various coatings and various furniture boards, more formaldehyde gas will be generated in the newly decorated room, resulting in indoor gas below the healthy standard, so generally just decorated The house needs to be vacant for a period of time, and the formaldehyde content can be reduced through ventilation or green plants. However, this method of natural ventilation or plant adsorption and reduction of formaldehyde takes a long time, and the efficiency of reducing the concentration of indoor formaldehyde is low, so it will choose to use formaldehyde. The adsorbent is used for formaldehyde adsorption. However, in order to ensure that the adsorbent is not easy to leak, the space of the carrier for the adsorbent is generally small, but on the one hand, it is easy to cause poor permeability and affect the adsorption efficiency of formaldehyde. On the other hand, due to the small space, it leads to and Blocked by dust in the air, resulting in further poor permeability
