在解决振动落砂机除尘问题上,吹吸式气幕除尘系统,已日益广泛地得到重视和应用。这种除尘系统的除尘装置,是靠条缝风口喷出的平面空气射流,经由吸风口吸入形成气幕,从而隔断两侧的空气,达到了防止落砂时含尘气体外逸的目的。同时,吹风射流又诱导含尘气体进入吸风罩。装置中由于吹吸气流的相互作用,改善了单一吸入气流的特性。据有关资料介绍,其排风量比单一的侧面吸尘罩通风装置减少了40～70％,并增加了对旁侧气流的抗干扰性能,提高了吸风效果。
In solving the vibration shakeout dust removal machine, blowing suction air curtain dust removal system, has been increasingly widely valued and applied. The dedusting device of the dedusting system is a plane air jets jetted by the slit tuyere and sucked into the air curtain through the air suction opening to cut off the air on both sides so as to achieve the purpose of preventing the escape of the dusty gas during falling sand. At the same time, the hair jet also induced the dust-laden gas into the suction hood. Due to the interaction of the suction flow in the device, the characteristics of the single suction flow are improved. According to the relevant information, the exhaust air volume is reduced by 40-70% compared with that of a single side dust cover ventilation device, and the anti-interference performance on the side air flow is increased, thereby improving the suction effect.
