The invention discloses a back-pack integrated
enzyme decontamination device comprising an
oxygen supply device, a decontamination device, a
mask and a spray gun, wherein the
oxygen supply device and the decontamination device are arranged on a back plate with straps together; one end of a fluid transfer tube is connected with the outlet end of a pressure-limiting valve; the inlet end of the pressure-limiting valve is connected with one end of a three-way tube; the other two ends of the three-way tube are connected with the fluid outlet tube of a fluid storage box and a
guide tube led to the spray gun respectively; and the other end of the fluid transfer tube and an
oxygen tube are led to the
mask. According to the back-pack integrated
enzyme decontamination device, the
oxygen supply device and the decontamination device are fixed on the back plate with the straps together to realize integrated arrangement, thus improving the portability of the device; and an
enzyme decontamination agent is divided into two paths after being pressurized via an electric pump, one path of the enzyme decontamination agent is conveyed into the
mask after being atomized via by an atomizer, and the other path of the enzyme decontamination agent enters the spray gun via the
guide tube. The device can also be used for conveying oxygen and atomized enzymes to the mask while being used for disinfecting a
polluted environment; and enzymes have the properties of detoxifying, repairing wounds, enhancing
nutrition and the like due to the characteristics of
detoxication and
nutrition enrichment after being inhaled by operating personnel.
