Sludge is the product of sewage treatment. The main characteristics of sludge are high water content (up to 99% or more), high organic content, easy to decompose and smell, which requires sludge drying treatment. The current sludge treatment process Among them, the drying method of sludge treatment still ranks first. Today, the editor summarized some technical solutions for sludge drying for your reference.
1. What does the product temperature mean in the drying process?
Sludge is a kind of ultra-fine powder with high organic content. The purpose of sludge drying is first to reduce and sanitize. Regardless of the final disposal method, sludge drying itself does not change the properties of the sludge, that is, temperature does not cause degradation of the sludge product or quality problems. In view of this, whether from the perspective of the quality of the sludge product or the efficiency of the dryer, the higher the temperature, the better. However, due to safety issues, most drying processes tend to reduce the temperature of the product as much as possible, that is, reduce the ignition energy of the so-called dust explosion.
