摘要： PROBLEM TO BE SOLVED: To prevent the clogging inside a waste heat recovery boiler due to the smoke ash contained in the exhaust gas of shredder dust, improve the boiler efficiency of the boiler, reduce the frequency of periodic cleaning of the boiler, and increase the quantity of the treated shredder dust.
SOLUTION: The first and second supply pipes 14 and 15 are provided on the ceiling part 11b on one end side of a furnace body 11. Shredder dust is fed inside the furnace body through the first supply pipe, and compressed oxidative gas is fed inside the furnace body through the second supply pipe, respectively. Flames are emitted inside the furnace body from a burner 12 provided on the wall part 11a on one end side of the furnace body to burn the shredder dust, and the exhaust gas generated by this combustion is allowed to pass through a waste heat recovery boiler 18 provided outside the furnace body to recover the waste heat of the exhaust gas. The shredder dust is fed inside the furnace body, and simultaneously, or after the combustion of the shredder dust, a reforming material is fed at a rate of 3 to 30 wt.% to the shredder dust of 100 wt.%.

摘要： PURPOSE:To provide a concentrate injecting device for preventing the concentrate leakage from a tuyere pipe and stabilizing the concentrate injecting operation, extremely effective for the safety and environment. CONSTITUTION:An outer cylinder 18 (a part of a tuyere pipe 3a) is fixed by welding coaxially to the tip part of an inner cylinder as the main body of the tuyere pipe 3a through a flange 19. A ceramic 20 having excellent wear resistance is formed by casting in the inner peripheral surface of this outer cylinder 18. Since the concentrate energetically dropped from a divided passage 4a by air flow is hit against the ceramic 20 of the tuyere pipe 3a, the damage to the tuyere pipe 3a is prevented. An annular projecting part 4c of a tuyere box 4 is fitted to the recessed part 3e of a reinforcing metal fitting 3. A screw part 18a is formed on the outer periphery of the tip part of the outer cylinder 18 and screwed with the screw part formed in the inner surface of the annular projecting part 4c of the tuyere box 4. That is, the tuyere pipe 3a is screwed into the tuyere box 4.

摘要： PURPOSE:To provide a recovering device for tellurium possible to enhance the contact efficiency of a solution containing tellurium with a packing material reactive with tellurium in the solution to shorten the reaction time. CONSTITUTION:The recovering device for tellurium recovers tellurium from the solution containing tellurium and is provided with a reaction tower 3 packed with a packing agent 2 forming a reactional product by reacting with tellurium in the solution, a tank 4 storing the solution, a pump 7 to feed the solution from the tank 4 to the bottom of the reaction tower 3, a return pipe line 8 to return the solution overflowing from the upper part of the reaction tower into the tank 4 and a drain 9 to discharge the reactional product precipitated in the tank 4.
