The disinfectant in the disinfectant spraying unit mainly contains 50-59.9% of ethanol, 0.2-1% (w/v) of peroxyacetic acid and 0.1-0.3% (w/v) of quaternary ammonium salt by volume concentration, is convenient to use and reliable in disinfection effect, and comprises a disinfection tube and an ultrasonic atomizer; the disinfectant is atomized and simultaneously introduced into the disinfection cavity, enters the liquid outlet pipeline 402 through the main liquid inlet pipe 401, after disinfectant water mist enters the liquid outlet pipeline 402, the inner diameter of the liquid inlet end of the liquid outlet pipeline 402 is the largest, the inner diameter of the liquid outlet pipeline 402 is in a three-section step shape along the flow direction of the disinfectant water mist, the inner diameter of the liquid outlet pipeline 402 is reduced in a step shape along the flow direction of the disinfectant water mist, the flow rate corresponding to the small pipe diameter is large, so that the flow in the whole liquid outlet pipeline 402 is approximately the same, the pressure of the disinfectant water mist in the whole liquid outlet pipeline 402 is ensured to be close, the pressure of the liquid outlet 403 far away from the main liquid inlet pipeline 401 is prevented from being too small, the water mist is difficult to be sprayed out or the defect that large liquid drops or liquid films are formed at the liquid outlet 403, the quantity and the pressure of the disinfectant water mist provided for the lead clothes in the disinfection cavity are basically consistent, and the spraying angle and the, the full-coverage type disinfection solution mist quantity can be more uniform for lead clothes in the disinfection cavity, and the liquid level effect in the disinfection cavity is ensured. And the amount of the disinfectant mist in the same disinfection chamber is more uniformly distributed when being sprayed, so that the concentration of the disinfectant is uniformly distributed, and the overall disinfection effect of the lead clothes is ensured. The utilization rate of the liquid outlet 403 and the mist outlet rate are also improved, and the spraying is ensured to be uniform. It should be noted that the number of the liquid outlet pipes 402 can be increased or decreased according to the specific disinfection chamber, so as to adapt to the liquid level of the uniform spraying inside. The function of the fan on the ultrasonic atomizer also enables the liquid outlet 403 entering the liquid outlet pipe 402 to have enough pressure, so that the problem that the normal operation of the ultrasonic atomizer is influenced due to the defect that the pressure of the liquid outlet 403 far away from the main liquid inlet pipe 401 is too small, water mist is difficult to spray out or large liquid drops or liquid films are formed at the liquid outlet 403 is avoided; meanwhile, the disinfectant has the advantages of dual effects of disinfection and decontamination, and the like, and the disinfection has no influence on the surface color of the lead protective clothing, the performance of the inner lead material and the outer nylon material; thereby prolonging the service life of the lead protective clothing.
More specifically, the specification of the ultrasonic atomizer is JYCS-18, the empty liquid generated by the built-in fan is used as power to atomize the disinfectant and simultaneously introduce the disinfectant into the disinfection chamber, the disinfectant enters the liquid outlet pipeline 402 through the main liquid inlet pipe 401, after the disinfectant mist enters the liquid outlet pipeline 402, the inner diameter of the liquid inlet end of the liquid outlet pipeline 402 is the largest, the inner diameter of the liquid outlet pipeline 402 is in a three-stage step shape along the flowing direction of the disinfectant mist, the inner diameter of the liquid outlet pipeline 402 is reduced in a step shape along the flowing direction of the disinfectant mist, the flow rate corresponding to the small pipe diameter is large, therefore, the flow rate in the whole liquid outlet pipeline 402 is equivalent to approximately the same, the pressure of the disinfectant mist in the whole liquid outlet pipeline 402 is ensured to be close, the pressure of the liquid outlet 403 far away from the main liquid inlet pipe 401 is prevented, the water mist is difficult to be sprayed out or the defect, therefore, the quantity and the pressure of the disinfection liquid mist supplied to the lead clothes in the disinfection cavity are basically consistent, the spraying angle and the spraying coverage area of the water mist quantity sprayed from the liquid outlet 403 are the same, the full-coverage type disinfection liquid mist quantity of the lead clothes in the disinfection cavity can be more uniform, and the liquid level effect in the disinfection cavity is ensured. And the amount of the disinfectant mist in the same disinfection chamber is more uniformly distributed when being sprayed, so that the concentration of the disinfectant is uniformly distributed, and the overall disinfection effect of the lead clothes is ensured. The utilization rate of the liquid outlet 403 and the mist outlet rate are also improved, and the spraying is ensured to be uniform. It should be noted that the number of the liquid outlet pipes 402 can be increased or decreased according to the specific disinfection chamber, so as to adapt to the liquid level of the uniform spraying inside. The effect of the fan on the ultrasonic atomizer also makes the liquid outlet 403 entering the liquid outlet pipe 402 have sufficient pressure, and prevents the pressure of the liquid outlet 403 far away from the main liquid inlet pipe 401 from being too low, and the normal operation of the ultrasonic atomizer is affected by the defect that water mist is difficult to spray or large liquid drops or liquid films are formed at the liquid outlet 403.
