Practical intelligent reminding device for formaldehyde removal

Abstract

The invention relates to the technical field of devices for formaldehyde removal, and discloses a practical intelligent reminding device for formaldehyde removal. The device includes a casing, whereina mixed liquid is arranged inside a closed box, a transparent glass plate is connected to a position right above the closed box, and a photoresistor is arranged right above the transparent glass plate; and a sodium hydroxide solution is arranged on the left side of the inner part of a filter box, an activated carbon adsorption plate is connected to the interior of the filter box, and a quicklimelayer is connected to the interior of the filter box. After chlorine gas is introduced into a hydrogen peroxide solution, peroxide ions are oxidized into superoxide ions firstly, a further reaction isperformed on formaldehyde and the superoxide ions, and a reaction is performed between formaldehyde and hydroxide ions further; since the superoxide ions are extremely unstable, excess energy is released in the form of photons when excited-state oxygen atoms are turned into ground-state oxygen atoms, and the resistance value of the photoresistor can be changed through the brightness of red light,so that the content of indoor formaldehyde is predicted further, the transfer amount of chlorine gas is controlled accordingly, and waste of materials is avoided.

Description

technical field [0001] The invention relates to the technical field of formaldehyde removal devices, in particular to a practical intelligent reminder device for formaldehyde removal. Background technique [0002] Formaldehyde has a pungent smell and can be smelled at low concentrations. Long-term exposure to formaldehyde can cause headaches, dizziness, fatigue, sensory disturbances, decreased immunity, and drowsiness, memory loss or neurasthenia, mental depression, and chronic poisoning on the respiratory system. The harm is also huge, long-term exposure to formaldehyde can cause respiratory dysfunction and hepatotoxic lesions, manifested as liver cell damage, abnormal liver radiation energy, etc. [0003] At present, there are many kinds of formaldehyde purification equipment, such as activated carbon adsorption, which has a saturation degree and needs to be replaced frequently without reminding to replace the device, making it difficult to grasp its saturation degree. The...
