基本原理:
BASIC PRINCIPLE
喷雾干化器是将污泥通过喷雾成雾状细滴分散于热气流中,雾化的液滴从塔顶喷下,而高温热气流或从塔顶与雾化液滴并流而下,经气-液数秒钟的接触传热。水分气化,干污泥产品从塔底引出,尾气则经旋风分离器分离后,进一步净化。
Sludge is sprayed into fine droplets and dispersed in the hot air stream. The high temperature hot air stream flows down from the top of the tower in parallel with the atomized droplets. The water is vaporized by gas-liquid contact heat transfer for several seconds. Dry sludge products are extracted from the bottom of the tower, and the tail gas is further purified after being separated by cyclone separator.
