Title:
THERMAL DECOMPOSITION EQUIPMENT
Document Type and Number:
Japanese Patent JP3507807
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide thermal decomposition equipment in which corrosion of a heating tube of a heating gas supply part or a thermal decomposition drum is suppressed at a reduced running cost.
SOLUTION: The thermal decomposition equipment is provided with a thermal decomposition drum 12 for indirectly heating waste by heated gas supplied from the heating gas supply part 102, and for thermally decomposing the heated waste into thermal decomposition residue and thermally decomposed gas. Heat gas supply part 102 is constituted of a 1st supplying means 103 for the heating gas for the starting operation and a 2nd supplying means 104 of the heating gas for the operation after the start up. The 2nd supplying means 104 of the heating gas is provided with a thermally decomposed gas combustion chamber 110 for burning the prescribed amount of the thermally decomposed gas out of the thermally decomposed gases from the thermal decomposition drum 12, a gas mixer 111 for mixing the gas discharged from a heating gas discharge part 30 of the thermal decomposition drum 12 and recovered at a gas recovery passage 105 side with the waste combustion gas from the thermally decomposed gas combustion chamber 110 and for producing the heating gas, and a gas neutralizing treatment apparatus 113 in the gas recovery passage 105.
