为探讨利用舰艇机械通风设备排除舱室染毒空气的可能性,我们测定了A型舰和B型舰的机械通风能力,并推算它们在某些染毒情况下的排毒时间。 结果表明,该两舰主要舱室换气次数为5.6～103次/小时,在沙林低浓度(0.4～1.5mg/m~3)染毒时,通风排毒时间为数至几十小时,在高浓度(50mg/m~3)染毒时,排毒时间在几百小时以上。调查认为,舱室空气低浓度染毒时,通风排毒具有一定效果。但需进一步加强舱室气密性、加强机械通风能力及配备空气喷雾消毒装置等,以提高舰艇化学防护能力。
In order to explore the possibility of using vessel mechanical ventilation to exclude airborne contaminants in the cabin, we measured the mechanical ventilation capacity of Type A and Type B ships and estimated their detoxification time under certain exposure conditions. The results showed that the ventilation rate of the two main vessels was 5.6 ~ 103 times per hour, and the detoxification time was several hours to several tens of hours at the low concentration of sarin (0.4 ~ 1.5mg / m ~ 3) (50mg / m ~ 3) when the poisoning, detoxification time in hundreds of hours or more. According to the survey, ventilation and detoxification have some effect when the cabin air is exposed to a low concentration of air. However, it is necessary to further enhance the airtightness of the cabin, enhance the mechanical ventilation capability, and equip the air spray disinfection device to enhance the chemical protection capability of the warship.
