Description

Technical Field

The high-temperature slag after incineration contains a lot of recyclable resources. During the resource recovery process, the slag needs to be cooled and dried. Therefore, in view of the above problem, a slag cooling and treatment device for coal-fired boiler is specially proposed. Utility Model Content

The condensate output end of the condenser 2 is fixedly connected to the first connecting pipe 1012, and the condensate input end of the condenser 2 is fixedly connected to the second connecting pipe 1013. The first connecting pipe 1012 is movably fixedly connected to the surface of the first annular pipe 109, and one end of the second connecting pipe 1013 is fixedly connected to the surface of the second annular pipe 1010.

[0027] By adopting the above technical solution, by setting the annular heat sink 105 and the circulating condenser 106, when the slag needs to be cooled, people pour condensate into the circulating condenser 106 through the condenser 2, the first connecting pipe 1012 and the liquid inlet pipe 107, and the high temperature on the surface of the polyphenylene sulfide heat exchange tube 104 can be absorbed by the annular heat sink 105, and then the annular heat sink 105 can be cooled by the condensate in the circulating condenser 106.
