INDUSTRIAL WASTE TREATMENT SYSTEM UTILIZING COMBUSTIBLE GAS PRODUCED BY THERMAL DECOMPOSITION

Japanese Patent JP3770948

B2

PROBLEM TO BE SOLVED: To provide a system wherein industrial wastes are thermally decomposed to produce a high-temperature combustible gas, the gas is burnt while it is forming a flame, and the thermal energy of the waste gas is used in industrial waste treatments chiefly including the incineration of industrial wastes in an incinerator, the melting of aluminum scraps as industrial wastes in an aluminum melter, and the neutralization and drying of waste concrete in a sludge dying oven.
SOLUTION: Waste plastics as industrial wastes are thermally decomposed in a double-kettle type carbonizer 1 to make a formed gas and activated coal. The activated coal can be used in many purposes such as an adsorbent for sewage treatment, a dry activated carbon adsorbent, a deodorizing agent and an earthquake-proofing material, and the formed gas is used as a fuel for an incinerator 3. Industrial wastes are burnt in the incinerator. The thermal energy of the waste gas is used to dissolve aluminum scraps as industrial wastes in an aluminum melter 5, and the melt is made into recycled aluminum. The heat of the waste gas is used to dry sludge in a sludge drier 8 to recycle the sludge. Water-soluble substances and soot are removed from the waste gas by means of a submerging apparatus 10, its heat is used in a heat exchanger 12, and the gas is converted into nonpolluting waste gas by utilizing the adsorptive action of the dry activated carbon 14.
