一、前言吹吸式通风是利用吹出气流和吸入气流的联合作用控制室内污染物的一种方法,具有工作稳定可靠、不影响工艺操作、排风量小等优点,因而得到日益广泛的应用。吹出气流输送能力强,速度衰减慢,隔断能力强,但吸入气流分布正好相反,两者联合作用消 I. INTRODUCTION Blow-aspirated ventilation is a method that uses the combined action of blowing air flow and inhalation air flow to control indoor pollutants. It has the advantages of stable and reliable operation, no effect on process operation, and small amount of exhaust air. It has been increasingly widely used. The blowing airflow has strong conveying capacity, slow speed attenuation, and strong blocking ability, but the distribution of inhaled airflow is just the opposite and the two combine to eliminate
