NOVELTY - Polycrystalline silicon ingot cooling generation system comprises a water heat exchanger and heat exchanger pump to pump water from the river and supplying to heat exchanger, where the water pump and heat exchanger is connected via pipeline, and further comprises a filter and water flow power generation device for generating electric power connected through pipeline. The filter is set with a water pump and heat exchanger connected with a pipeline and filtering water flow through pipeline. The filter comprises e.g. first filter, second filter, the first pipe, the second pipe and third pipe.    USE - Used as polycrystalline silicon ingot cooling generation system.    ADVANTAGE - The system saves energy consumption, and can filter river water.    DETAILED DESCRIPTION - Polycrystalline silicon ingot cooling generation system comprises a water heat exchanger and heat exchanger pump to pump water from the river and supplying to heat exchanger, where the water pump and heat exchanger is connected via pipeline, and further comprises a filter and water flow power generation device for generating electric power connected through pipeline. The filter is set with a water pump and heat exchanger connected with a pipeline and filtering water flow through pipeline. The filter comprises first filter, second filter, the first pipe, the second pipe, the third pipe, the fourth pipe, the fifth pipe, main water inlet pipe and a water outlet pipe. The first pipe and third pipe are connected with first filter. The second pipe and fourth pipe is connected with the second filter. The first filter is set with the first filter screen. The first filter first compartment is set with first inlet chamber and first outlet chamber. The second filter is provided with a second filter screen. The second filter second compartment is set with second inlet chamber and second outlet chamber. The first pipe is connected with first inlet chamber. The third pipe is connected with first outlet chamber. The second pipe is connected with second inlet chamber. The fourth pipe is connected with second outlet chamber. The first outlet chamber is connected with second outlet chamber through the fifth pipe. The first filter bottom part and first inlet chamber is connected with first drain valve. The second filter bottom part and second inlet chamber is connected with second drain valve. The first pipe, the second pipe, the third pipe, the fourth pipe, and the fifth pipe is provided with control valve. The power generation device is connected with the heat exchanger.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the polycrystalline silicon ingot cooling generation system.
