Active formaldehyde absorption and disposal integrated system and working method thereof

Abstract

The invention relates to an active formaldehyde absorption and disposal integrated system which comprises a gas-collecting hood. A gas inlet of the gas-collecting hood is communicated with the lower portion of a bio-processor through a spiral absorption tube component, absorption liquid for dissolving formaldehyde is placed in an inner cavity of the spiral absorption tube component, an inner cavity of the bio-processor is filled with biological stuffing, and a gas outlet is formed in the upper portion of the bio-processor. The invention further relates to a working method of the active formaldehyde absorption and disposal integrated system. The active formaldehyde absorption and disposal integrated system is simple and reasonable in structural design, can efficiently, conveniently and rapidly degrade the formaldehyde and has a wide application prospect.

Description

technical field [0001] The invention relates to an active formaldehyde absorption and disposal integrated system and its working method. Background technique [0002] In recent years, due to indoor air pollution directly endangering health and life, coupled with the continuous enhancement of people's awareness of environmental protection, more and more decoration owners are no longer satisfied with simple decoration, but require a comfortable, healthy and elegant Living Environment. Among these various harmful gases, formaldehyde is the most harmful to the human body. Studies have shown that formaldehyde has strong carcinogenic and cancer-promoting effects. Among all contacts, children and pregnant women are particularly sensitive to formaldehyde and are more harmful. Therefore, in order to maintain the health of yourself and your family, it is imperative to do a good job in indoor formaldehyde treatment. Doing a good job in indoor formaldehyde treatment is equivalent to t...

However, most of the formaldehyde treatment on the market can only target the free formaldehyde in the air, and has no effect on the unreleased formaldehyde inside the board, or the effect is not ideal, that is, after the treatment is completed, the air quality is only temporarily improved. After a month, it may rebound again, because the free formaldehyde inside the wood-based panels or other furniture is released again. Therefore, this passive treatment method can only treat the symptoms but not the root cause.

[0003] The traditional formaldehyde treatment methods are mainly physical adsorption and chemical oxidation. The physical adsorption is mainly based on the adsorption of activated carbon. This adsorption method is easy to cause adsorption saturation, and the adsorption material must be replaced continuously, which is low in efficiency and high in cost; while chemical oxidation is usually It uses the strong oxidizing properties of reagents, especially the use of titanium dioxide. This method requires long-term spraying, which is easy to cause air pollution, and the light energy efficiency of titanium dioxide catalyst in the photocatalyst is only about 3%, and the treatment effect is far from theoretical. Ideal, and long-term use will also affect the color of the furniture surface, and the production cost is high, lacking practicality and safety

In addition, the above-mentioned treatment methods are single-time treatment of gaseous substances, and the treatment efficiency is low. Therefore, how to find a high-efficiency and low-cost treatment method is a hot spot in current market research.
