Environment-protection process capable of effectively preventing formaldehyde in furniture from harming human body health

Abstract

The invention provides an environment-protection process capable of effectively preventing formaldehyde in furniture from harming the human body health. The process comprises the concrete steps that the furniture is placed into a sealed cabin, a door of the sealed cabin is closed, a strong force exhaust fan is started for forcibly extracting out the formaldehyde on the furniture surface, the negative pressure stillness is maintained for 5 to 10 hours, the furniture is subjected to high-temperature wax spraying polishing in the negative pressure state, and the wax sealing on the formaldehyde ingredient inside the furniture is realized. The extracted air is conveyed into a formaldehyde absorption tower to be subjected to water spraying collection recovery, and the spraying water is cyclically utilized. The environment-protection process has the beneficial effects that the method process is environment-friendly, feasible and practicable, the practicable on the furniture surface can be forcibly eliminated, and in addition, the volatilization of the formaldehyde inside the furniture can also be effectively prevented through the wax sealing, so the harm of the formaldehyde in the furniture to the human body health can be avoided.

Description

technical field [0001] The invention relates to the technical field of purification, in particular to an environmental protection process capable of effectively preventing furniture formaldehyde from harming human health. Background technique [0002] The latest research shows that formaldehyde has become the first carcinogen. Formaldehyde causes human nasopharyngeal cancer, nasal cavity cancer and sinus cancer, and can cause leukemia. According to the national mandatory standard, after closing the doors and windows for one hour, the amount of formaldehyde released in each cubic meter of indoor air shall not exceed 0.08 mg; if it reaches 0.1-2.0 mg, 50% of normal people can smell the odor; if it reaches 2.0-5.0 mg , the eyes and trachea will be strongly stimulated, and symptoms such as sneezing and coughing will appear; if it reaches more than 10 mg, it will cause dyspnea; if it reaches more than 50 mg, it will cause pneumonia and other critical diseases, and even cause deat...
