Abstract

The invention discloses a treatment method for efficiently absorbing formaldehyde, which comprises the following steps: fully mixing air with formaldehyde absorption liquid through a gas-liquid mixer,and carrying out gravity phase splitting to implement gas-liquid separation, thereby obtaining formaldehyde-removed air. The invention further discloses a treatment device for efficiently absorbing formaldehyde. The device comprises a sucking pump, a gas-liquid mixer, a liquid storage barrel and a circulating pump, wherein a gas inlet and a liquid inlet of the gas-liquid mixer are connected withthe sucking pump and the circulating pump respectively, a liquid outlet of the gas-liquid mixer is connected with the liquid storage barrel, an exhaust port is formed in the upper portion or the sidewall of the liquid storage barrel, and a liquid outlet is formed in the lower portion of the liquid storage barrel and connected with the circulating pump. The treatment device for efficiently absorbing formaldehyde provided by the invention is simple in structure and easy to operate, and after air and the absorption liquid are fully mixed, most formaldehyde is absorbed by the absorption liquid and then is subjected to gas-liquid separation with clean air, so that the effect of efficiently removing formaldehyde with high quality is achieved.

Description

technical field [0001] The invention relates to the field of cleaning technology, in particular to a treatment method and device for efficiently absorbing formaldehyde. Background technique [0002] In today's society, indoor formaldehyde hazards have become a major killer that threatens human health in today's society. [0003] In the prior art, the method of formaldehyde treatment is usually to remove formaldehyde by absorption treatment or filtration, and the device for formaldehyde absorption treatment is usually carried out through absorption tower or packed tower or multi-layer filter device, the absorption tower or packed tower is due to formaldehyde The contact surface area of ​​the formaldehyde is limited, and it is usually necessary to make the absorption tower and the packed tower large and high to facilitate the full mixing of the formaldehyde absorption liquid and air in order to obtain a certain effect. The filter device is also expensive because the filter me...
