Embodiment Construction

[0025] as attached figure 1 As shown, the present invention mainly includes feeding device 1, pyrolysis furnace 2, turning grate 3, hydraulic device 4; Feed chute 11 and separation device 12.

[0026] Under the action of the high-temperature pyrolysis fan 6, the high-temperature flue gas enters from the hot air pipe 7, enters the pyrolysis furnace 2 through the pipe 5, and heats the broken paint bucket at a high temperature, and the heated flue gas is sent to the incinerator again through the pipe 8 to burn. Under the toasting of the continuously entering high-temperature hot air, the paint bucket fragment iron sheet in the pyrolysis furnace 2 is separated from the iron sheet after high-temperature carbonization. After being heated at a high temperature, the fire grate 3 is rotated and turned over. Simultaneously, the flap valve 9 is opened, and the processed paint bucket iron sheet enters the separation device 12 through the discharge chute 11. In this way, the iron sheet...

Abstract

The invention discloses a method and a device for applying waste heat of a solid waste incineration system to treatment of waste paint buckets. By application of the method and the device, high-temperature flue gas generated in an original rotary kiln (or fluidized bed) and secondary combustion chamber integrated incineration system is fed into a pyrolyzing furnace through a pyrolyzing fan to realize pyrolysis of the waste paint buckets, products obtained by pyrolyzing are sent into a mechanical separation device, generated pyrolysis tail gas is sent into the original rotary kiln (or fluidized bed) and secondary combustion chamber integrated incineration system to realize further treatment, tail gas generated after treatment passes through an original flue gas purification system, and purified flue gas is directly discharged into a chimney. The products obtained by pyrolyzing are separated in the mechanical separation device to recover waste metals, and residues are sent to the original rotary kiln (or fluidized bed) and secondary combustion chamber integrated incineration system to realize retreatment. Due to systematic combined design, reasonability and compactness in connection of integrated devices are realized, structural maturity of adopted equipment is realized as well, and high economy and social benefits are achieved.

Description

technical field [0001] The invention relates to a method and a device for utilizing waste heat of a solid waste incineration system to separate and recycle broken paint barrels after carbonization treatment, and to reprocess carbonized paint. Background technique [0002] With the development of social economy and industrialization, especially in the construction, installation, shipbuilding industry and other industries, a large number of waste paint buckets are produced. The waste paint buckets produced every year not only occupy a large number of sites and warehouses, but also create certain environmental pollution. Pollution and potential safety hazards restrict the development space of enterprises. This problem has become a headache for many industries. Taking a shipyard in Zhoushan as an example, the waste paint barrels produced after the paint used in the shipbuilding reach nearly 1,000 tons per year, and the existing site has a backlog of more than 20,000 tons of rese...
