Introduction

PHNIX's belt-type waste-heat low-temperature drying technology utilizes industrial waste heat sources such as flue gas, steam, and natural gas waste heat to dry sludge in a low-temperature, enclosed environment. The moisture in the sludge is converted into humid air, which is then cooled and dehumidified by the drying system to achieve the drying of the material.

This technology offers several advantages, including low exhaust temperature, strong drying capacity, high efficiency, and low operating costs. It can reduce the moisture content of sludge from 82% to 10%-60%, achieving over 50% energy savings and an 80% reduction in sludge volume.

As a low-energy, pollution-free drying and volume-reduction technology, it is widely used in the drying and volume-reduction projects of municipal and industrial sludge (such as from textile dyeing, papermaking, electroplating, chemical, leather, and pharmaceutical industries), livestock biogas residues, and animal feed.

Advantages of the process package
