Abstract

The invention discloses RDF (refuse derived fuel) production equipment. The equipment includes a crushing box internally equipped with a crushing mechanism, the top of the crushing box is equipped with a feed inlet, the bottom of the crushing box is equipped with a crushing discharge port, and a mixing box communicated with the crushing discharge port is disposed under the bottom of the crushing box. The box wall of the mixing box is equipped with an additive feed inlet, the mixing box is internally equipped with a stirring shaft, one end of the stirring shaft extends out of the box wall of the mixing box and is in power connection with a stirring motor, and the other end of the stirring shaft is connected to a screw conveying extrusion moulding machine. The screw conveying extrusion moulding machine includes a shell communicated with the mixing box and a screw conveying shaft coaxially connected to the stirring shaft. The equipment also includes a heating device for heating the mixingbox or the shell of the screw conveying extrusion moulding machine. The invention also provides an RDF preparation method using the RDF preparation equipment. The equipment and method provided by theinvention can increase the combustion heat of refuse derived fuel, have no need for an adhesive, are beneficial to environmental protection and are convenient for storage and transportation.

Description

technical field [0001] The invention relates to the technical field of domestic waste treatment, in particular to RDF fuel production equipment and a preparation method of RDF fuel. Background technique [0002] Traditional domestic waste treatment technologies mainly include incineration, landfill, composting, and waste sorting and recycling. Among the conventional technologies for waste disposal, incineration has the advantages of obvious reduction effect, complete harmlessness, small footprint, utilization of waste heat energy, and less secondary pollution, which meets the strategic requirements of my country's sustainable development. Compared with traditional waste treatment technology, RDF (RefuseDerived Fuel) fuel production technology can turn waste into treasure, and compress the mixed additives of domestic waste into RDF fuel, which can greatly improve the energy density of waste, and the combustion efficiency is better than that of raw waste. Significantly improv...
