Abstract

The invention discloses a formaldehyde fumigation method and a formaldehyde fumigation device. According to the invention, the contact time of formaldehyde and potassium permanganate can be well controlled, so that formaldehyde can fully react, and no formaldehyde liquid being left is ensured, and the effect of fumigation for a sealed room is achieved; formaldehyde and potassium permanganate reacts after an operator leaves the room to be disinfected, so that open fire is avoided during the whole fumigation process, and the safety of the operator is ensured.

Description

technical field [0001] The invention relates to a method for fumigation and disinfection of formaldehyde, and also relates to a device for fumigation and disinfection of formaldehyde. Background technique [0002] The currently used formaldehyde fumigation method is to add formaldehyde into a stainless steel container, place the container on a stand, heat it with an alcohol lamp, and evaporate the formaldehyde in the indoor fumigation method. The disadvantage of this method is that the operation is cumbersome and there are potential safety hazards: The method needs to light the alcohol lamp before the operator can leave the room. At this time, the formaldehyde has begun to volatilize, which will affect the health of the operators who have not left the room, and even cause symptoms of formaldehyde poisoning. Severe formaldehyde poisoning will be life-threatening; the alcohol lamp is an open flame. , may cause a fire hazard. Contents of the invention [0003] In order to so...
