摘要
针对原有脉动流化干燥机存在的脉动效果不够理想、物料输送不够流畅等问题,研制了一种新型的脉动振动流化干燥机。它采用导流半径依次增大的导流装置,改善了气流在床层内分配的均匀性;采用三叶片式脉动装置,改善了脉动效果;增设了振动装置,使物料输送流畅;增设了导料装置,从根本上解决了物料的“反流”问题。与原有干燥机相比,其具有结构简单、质量轻、床层压降小、干燥均匀等优点,而且节能优势明显。
A new type pulsing fluid - bed dryer was developed based on the original model that had shortcoming of not ideal pulsing effect and not smooth conveying of materials. In the new dryer, the air guiding device with an orderly increased air guiding radius was introduced to improve the uniformity of airflow distributed in bed; a three -blade device was installed to get a good pulse-fluidizing effect; an vibrating device and a conducting device were additionally set up to make materials flow fluent and to overcome “reverse flow”respectively. The new type dryer is characterized not only by simple and light structure, low pressure drop and uniform drying,but also by obvious energy saving.
