Description

Remove formaldehyde ware and remove formaldehyde device

Technical Field

The utility model belongs to remove formaldehyde product field, concretely relates to remove formaldehyde ware and adopt this formaldehyde removal device who removes formaldehyde ware.

Background

The world health organization lists formaldehyde as one of the main indoor pollutants in the indoor air quality health guide (hereinafter referred to as the guide) and indicates that the formaldehyde has serious influence on human health. About 200 articles on "cross-linking of formaldehyde with DNA proteins", "formaldehyde with genotoxicity and blood and lymphatic system", "formaldehyde with cancer and meta-analysis" and the like searched by information retrieval systems are pointed out in the guideline, and literature studies have shown that formaldehyde is associated with allergy, asthma, irritation of the trachea, narrowing of the bronchi, irritation of the eyes, inflammation, irritation of the nose, lungs, illness of infants, trigeminal nerve irritation. Studies have shown that exposure to formaldehyde at a concentration of 0.36 mg/cubic meter for 4 hours causes irritation to the human eye, and exposure to formaldehyde at a concentration of 0.6 mg/cubic meter increases the frequency of blinking and redness of the conjunctiva. Studies have shown that asthma in children is associated with low formaldehyde exposure, and that the exhalation of children is significantly increased by nitric oxide when the formaldehyde concentration is higher than 0.06 mg/cubic meter.

With the development of civilization and improvement of living standard of human society, the decoration of the environment changes the living space in the traditional sense, so that the ecology of the house space is diversified day by day, however, just for the demand, the danger is natural while people enjoy the peace and happiness, and related statistics are carried out by indoor air detection enterprises or departments in China, and more than 90 percent of harmful gas (mainly formaldehyde) in newly decorated rooms is displayed to be out of standard. In order to ensure the human health in the residential house, the aldehyde in the residential house needs to be removed and controlled.

China is a large consumption country of artificial boards, and the output and sales of artificial boards are famous in the second place in the world nowadays. Formaldehyde pollution in indoor environments is mainly caused by artificial boards (such as plywood, core board, medium density fiberboard, particle board, etc.) used as interior decorations, and the artificial boards are also widely used for furniture, doors, floors, etc. made of the artificial boards. According to investigation, a set of artificial board wardrobe needs to consume 30-35kg of formaldehyde, and the estimation is carried out according to the following conditions: the artificial board adopted for decorating one hundred square meters of three living rooms consumes more than 100 and 200kg of formaldehyde, which is a great hazard to the human body living in the board. However, the formaldehyde release process in furniture made from wood-based panels is slow and it takes a long time (months to years) for a new house to reduce the formaldehyde concentration to a level that is only slightly harmful or harmless to the human body. Therefore, in order to better ensure the health of human bodies, products for purifying and removing formaldehyde are necessary to be used.

At present, the products for purifying and removing formaldehyde on the market and the working principle thereof are mainly three types:

the first one is physical adsorption (such as publication numbers CN205073797U (a filter device for formaldehyde treatment) and CN208547087U (a fresh air system capable of removing formaldehyde)), which is mainly used for various air purifiers, but the main performance of the physical adsorption is to adsorb suspended matters in air, and has a certain adsorption effect on indoor formaldehyde. Although simple and safe in this way, it is slow to take effect and requires a certain time.

Secondly, harmful gas adsorber (such as publication No. CN107174936A (pretreatment system and operation method of high concentration VOC waste gas containing phenol and formaldehyde)) adopts catalysis technology or chemical reaction technology to decompose harmful odorous gas in the air into harmless tasteless substance, belongs to chemical adsorption, and decomposes while adsorbing, and has strong pertinence and high efficiency, but chemical adsorption has certain potential safety hazard and needs attention.

And thirdly, a material sealing technology, namely a sealing material, namely a formaldehyde sealing agent (photocatalyst) is adopted. The formaldehyde gas sealing agent is used for sealing formaldehyde gas in furniture and artificial boards, thereby effectively reducing the formaldehyde emission in various artificial boards. However, the method is a method for treating symptoms and root causes, and although the indoor formaldehyde concentration is reduced, formaldehyde is not removed fundamentally, and potential safety hazards still exist. Moreover, such sealing materials are still under development with a certain uncertainty.

From the above, most formaldehyde removing devices in the prior art have the following disadvantages:

1. long time consumption, complex treatment process and unsatisfactory treatment effect

Free formaldehyde in the air is adsorbed or decomposed (in the using process, consumables for adsorption or decomposition need to be replaced in time, otherwise the treatment effect is greatly reduced, but the use cost of a user is increased), the formaldehyde is difficult to prevent from entering the human body, and the formaldehyde can only be used as a passive precaution measure. And to effectively reduce the formaldehyde content requires a treatment time during which the human body is preferably not exposed to such an environment for a long period of time.

2. The product has more complex structure and higher price

Many of the purification devices on the market are expensive and have poor formaldehyde purification capacity. Therefore, new houses and new furniture can not be used for the first time after the purchase, the life of people is greatly unchanged, and the formaldehyde-free board is too expensive and can not be removed from the source.

Based on this, the applicant considers to design a formaldehyde remover which can effectively remove formaldehyde released by furniture and has lower cost. And further consider to design a formaldehyde removing device adopting the formaldehyde removing device.
