High-efficiency energy-saving emulsion system used for cold continuous rolling unit

The invention relates to a high-efficiency energy-saving emulsion system used for a cold continuous rolling unit. The high-efficiency energy-saving emulsion system used for the cold continuous rollingunit comprises two emulsion circulation loops, each emulsion circulation loop comprises an emulsion box, an ash filter, a working pump and a lifting return pump, the output end of each emulsion box is connected with the working pump, the output end of the working pump is connected with an injection system of a rack through a pipeline, the output end of the lifting return pump is connected with the ash filter and used for sending emulsion recovered by the rack back to the ash filter so that filtering can be carried out, the output end of the ash filter is connected with emulsion box, each emulsion box corresponds to at least one ash filter, each emulsion circulation loop further comprises a circulation pump, one end of each circulation pump is connected with the corresponding emulsion box,the other end of each cir
