Abstract

The invention discloses a formalin neutralization box. The formalin neutralization box comprises a formalin gas inlet, a gas outlet and an electric air valve, wherein the formalin gas inlet is connected with an ammonia gas generator, the ammonia gas generator is connected with a urotropine collection device, and the urotropine collection device is connected to the gas outlet; a controller is arranged in the formalin neutralization box. The formalin neutralization box further comprises an ozone generator, an ozone gas outlet and an electric air valve. The formalin neutralization box disclosed by the invention can be used for transferring the neutralization process of formaldehyde gas and ammonia gas, which is performed in a sterilized space in the past, into the neutralization box for neutralization reaction, effectively collecting generated urotropine white crystals in the neutralization box and facilitating cleaning of urotropine; meanwhile, the purpose of thoroughly removing the residual formaldehyde gas in the sterilized space can be realized.

Description

technical field [0001] The invention relates to a disinfection and sterilization device, in particular to a formalin neutralization box. Background technique [0002] The aqueous solution containing 37%-40% formaldehyde is called formalin. After heating formalin into gas, it has a broad-spectrum and high-efficiency sterilization effect. It has been widely used in hospitals, pharmaceutical factories and other places that require thorough sterilization. . Since formaldehyde has a strong smell and is harmful to the human body, it is necessary to neutralize the formaldehyde still contained in the sterilized space. Previously, people used ammonia vapor to pass into the sterilization space for neutralization. The chemical reaction equation is: [0003] 6 HCHO+4 NH 3 →C 6 h 12 N 4 +6H 2 o [0004] C 6 h 12 N 4 Hexamethylenetetramine, also known as urotropine, is a non-toxic and odorless white crystal, which forms C after neutralization 6 h 12 N 4 Will remain on w...
