Abstract

The invention discloses a system for making sludge into regenerated solid fuel. The system comprises a sludge storage unit, a drying unit, weighing unit, a conveying unit, a granulating unit 8 and a combusting unit which are sequentially arranged. By means of the system, sludge is dried, and dried sludge, coal powder and rice straw are mixed and granulated to form sludge regenerated solid fuel high in combustion value. The system is simple in structure, small in occupied area and high in production efficiency.

Description

Technical field: [0001] The invention relates to the technical field of sludge treatment, in particular to a system for making sludge into regenerated solid fuel. Background technique: [0002] According to the "China Sludge Treatment and Disposal Market Analysis Report (2013 Edition)", by 2015, the production of wet sludge (with a moisture content of 80%) in urban sewage treatment plants across the country will be 33.59 million tons per year, that is, the daily sludge output is 9.2 tons. However, the status quo of domestic sludge treatment and disposal is not optimistic. The main methods of sludge treatment in my country are composting, building material utilization and incineration. In addition, as many as 17.76% of sludge disposal is unknown. [0003] The new process technology of sludge treatment is to turn waste sludge into renewable fuel, and through the technical process of dehydration, sterilization, deodorization, drying and loosening, the calorific value in sludg...
