Abstract

The invention discloses a hospital waste gas treatment device and method which can sterilize and disinfect waste gas exhausted by a hospital and can prevent the hospital waste gas from carrying viruses, disease treatment bacteria and fungi. The hospital waste gas treatment device comprises an air suction pipe, a U-shaped ultraviolet sterilization pipe, an exhaust fan, a first filter, a booster fan, a disinfection tank and a second filter. The hospital waste gas treatment method comprises the steps that S1, the air volume of an exhaust fan is adjusted to enable the air volume in an air suctionpipe to be 5-15 m <3> / min; S2, the wavelength of an ultraviolet lamp is controlled to be 250-270 nm through an ultraviolet lamp controller; S3, a booster fan is adjusted to enable the air pressure torange from 30 pa to 80 pa; S4, 84 disinfectant with the effective chlorine concentration of 1000 mg / L is added into the disinfection tank; and S5, a heating device is arranged at the bottom of the disinfection tank, so that the temperature in the disinfection tank is 30-45 DEG C. By adopting the hospital waste gas treatment device and method, the risk of disease infection caused by hospital wastegas can be effectively reduced; the purification effect can be effectively improved; and the hospital waste gas treatment cost is reduced.

Description

technical field [0001] The invention relates to hospital waste gas treatment, in particular to a hospital waste gas treatment device and method. Background technique [0002] It is well known that the existing hospital exhaust gas treatment generally only extracts the air through the exhaust fan, and then installs an air purifier in the treatment room, so as to realize the purification of the air in the hospital. However, the treatment of the air excluded from the outside world in the hospital is less, and the sterilization and disinfection are not thorough enough, so it is easy to cause infectious diseases to spread and spread through the air. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hospital waste gas treatment device capable of sterilizing and disinfecting hospital waste gas and preventing hospital waste gas from carrying viruses, pathogenic bacteria and fungi. [0004] The technical solution adopted...
