Incineration method of household waste and manufacturing method of inorganic molding using the incineration material

摘要

The present invention continuously and quickly incinerates various wastes such as food waste, such as residues from the kitchen, dehydrated cakes after sewage treatment, tap water sludge, and other combustible wastes such as mine wastes. The present invention relates to a method of incineration of household waste and to a method of manufacturing an inorganic molded product using the incineration ash, which has been processed, molded by adding other raw materials to the incineration ash, and fired to produce a harmless and environmentally friendly ceramic product. In the process of crushing household wastes such as trash, the net magnetic trash which has been removed with magnetic material is crushed, and the sorting machine selects bulky combustible materials, and the residue is kneaded with continuous dehydration sludge (water content 30-40) %) And sewage treatment dehydrated cake (water content 30-40%) and tap water The sludge (water content 25-30%) is stored directly in the box feeder, and the dehydration liquid is filtered through a filter press (water content 25-30%) in the sludge box feeder, and the filtrate is pollution prevention facility. It is used as a spraying water and cooling water for incineration, and it is evaporated and consumed. 0-30 weight% of kneaded pumice (calorie value 1200-3000kcal / kg) is coarsely pulverized (12-30 mesh), and then kneaded and kneaded. Extrusion molding (moisture content 14-20 weight%) is used in the mold, and the shape of the mold is a tube with a circular hole in the center of the cross section, so that oxygen can be easily supplied when heated, Bulk combustible material is charged to the kiln and dried and burned at the baking table (700-1000˚C), and the combustion gas is sent to a known pollution prevention facility by spraying and removing slaked lime slurry and water. Clay at 80% weight 20-40% by weight and 0-5% by weight of limestone are added after mixing and stirring by pulverizing and grinding after the grinding process, and then molded into a mold by vacuum molding, and the molding is dried or calcined by pressure molding. Through the process, the calcining temperature is carried out in a range of 700-1000 ° C., the firing temperature is 1000-1300 ° C., and the firing time is fired within a range of 10-30 hours.
