Double-filtering back-flushing self-decontamination water taking device and working mode thereof
The invention discloses a double-filtering back-flushing self-decontamination water taking device which comprises a water taking opening. The water taking opening penetrates through a dam and is provided with a filtering device. The water taking opening is connected with a water taking pipe. A back-flushing pipe is arranged on the water taking pipe. Back-flushing supercharging devices are arranged on the water taking pipe and the back-flushing pipe. The water taking opening is in a loudspeaker shape. One end, with small opening diameter, of the water taking opening is arranged in the dam. The filtering device comprises a coarse filtering screen and a fine filtering screen. One end, with large opening diameter, of the water taking opening is provided with the coarse filtering screen. The fine filtering screen is arranged in the middle of the water taking opening. According to the double-filtering back-flushing self-decontamination water taking device, the problems that in the prior art, a water taking opening filtering screen is blocked, decontamination difficulty is high, and equipment normal operation is affected are solved. The reliability and the safety of water supply system equipment operation are greatly improved, the fact that a unit can generate much power safely and continuously, and the power generation efficiency of an enterprise is improved.
