Treatment of waste from coal burning thermal power plant
专利汇可以提供Treatment of waste from coal burning thermal power plant专利检索，专利查询，专利分析的服务。并且PURPOSE: To treat the acidic waste and alkaline waste from a coal burning thermal power plant at lessened water consumption in the state of without causing pollution by mixing said waste then separating fine materials from the liquid and circulatively using the neutralizig liquid thereof.
CONSTITUTION: The waste gas of a coal burning boiler 1 is flowed via a pipeline dust collector 2 into an absorption tower 7c. If water contg. limestone powder is sprayed from spray nozzles 7e, the SO
3 and SO
2 is the waste gas react to form CaSO
4 . The fly ashes captured in an electrical dust precipitator 2 are supplied into a hopper 14, and the proper amount thereof is fed to a mixer 15, where it is humidified by the water sprayed from a nozzle pipe. The muddy gypsum extracted from the bottom part of the tower 7c is fed to a thickener tank 28, the supernatant whereof 9W10pH is supplied to a waste water treatment tank 29. Part of the humidified flyashes are removed from the mixer 15 and are supplied to the tank 29.
