Description

Remove formaldehyde purifier

Technical Field

The utility model relates to an air purification technical field specifically is a remove formaldehyde purification device.

Background

Along with the progress of the industrial society, formaldehyde pollution in the decoration materials is generated, and the formaldehyde has potential, slow and serious harm to human bodies and is listed as a carcinogen by the world health organization. The artificial board is mainly an artificial board which is used in large amount as decoration materials, and the artificial board contains a large amount of adhesive resin which accounts for more than 30% of the mass of the artificial board. There are three main types of common adhesive resins: urea-formaldehyde resin obtained by condensing urea and formaldehyde; phenol-formaldehyde resins obtained by condensation of phenol and formaldehyde; melamine resin obtained by condensing melamine and formaldehyde. In the condensation process of the resins, free formaldehyde which does not participate in the reaction is carried due to incomplete reaction, the free formaldehyde is very volatile, and the low-concentration formaldehyde mixed in the air cannot be detected by human beings, so that chronic injury is easily caused.

Chlorine dioxide also has excellent removal effects on indoor air pollutants such as formaldehyde, hydrogen sulfide, ammonia, nitrogen oxides, tar, nicotine, mold and the like, and is safe and harmless. Therefore, the method is also suitable for removing decoration pollution, treating indoor air pollution, disinfecting air in a vehicle and the like. However, chlorine dioxide itself is unstable and rapidly decomposes under the influence of light and temperature, and although there is no residue or side effect after use, it is difficult to maintain the disinfection and purification effect for a long time.

At present, chlorine dioxide is mainly used as a chlorine dioxide slow-release agent, the existing chlorine dioxide slow-release agent is mainly prepared by simply mixing sodium chlorite, solid acid or liquid acid, and is suitable for fruit and vegetable fresh-keeping and treatment and application of pollutants in air, but the release amount of the chlorine dioxide slow-release agent meets the requirement of evaluation of air disinfection. At present, chlorine dioxide slow release agent products mainly comprise two types:

1) sodium chlorite is reacted directly with liquid or solid acid. Such product defects are: the storage and transportation of the liquid acid are unsafe, the chlorite and the acid directly react during the use, the burst release is caused, the release is not uniform, and if no good stable technology exists, the active sodium chlorite easily reacts with the acid under the unactivated condition, so the danger is generated.

2) The chlorine dioxide is absorbed by polymer or substance with large specific surface area and is released slowly when in use. Such product defects are: free chlorine dioxide exists in the product, and the chlorine dioxide can be continuously released even if the product is not used, so that the product can not meet the quality guarantee period requirement of a disinfectant; due to the limitation of absorption capacity, the content of the effective chlorine dioxide released by the product is very low, and the requirement of disinfection technical specifications cannot be met.

In addition, in order to increase the effective chlorine dioxide content and increase the reaction rate, many techniques combine the components such as acid and chlorite in a solid-liquid two-phase manner, and the components are separated by a diaphragm or other structures, and are mixed to release chlorine dioxide when in use. The method has the risk of liquid leakage in the process of storage and transportation; the oxidative properties of chlorine dioxide can also cause damage to other items if activated to release large amounts of chlorine dioxide in a confined space; even an explosion may result if a large amount of chlorine dioxide is not immediately available.
