转运点物料输送过程会产生复杂的气流,其影响气流规律的因素较多。微粒在自由下落过程中会携带环境空气进入料流间隙,并随料流运动,其料流又对周围空气存在一定的拽曳作用,导致周围空气随物料运动,当物料下落并撞击底部皮带时,其夹带的空气从料流中析出,分散在空间中形成絮乱的复杂气流,而紊乱气流的运动使得吸附在煤块上的细小粉尘颗粒弥散到周围空气中造成污染。 Transfer point of material handling process will produce complex air flow, the air flow law of the factors. Particles in the process of free fall will carry ambient air into the material flow gap, and with the flow of movement, and its flow around the air there is a certain drag, resulting in the surrounding air with the material movement, when the material drops and hit the bottom of the belt , Entrained air is precipitated from the stream and dispersed in the space to form a complex flow of flocs. The movement of the disturbed airflow causes fine dust particles adsorbed on the lumps of coal to diffuse into the surrounding air and cause pollution.
