The utility model relates to a zero-discharge atomizing continuous dyeing system, which needs no dip dyeing of cloth, and is free of feed liquid discharge and capable of continuously dyeing. A plurality of rows of gate-type atomizing pipe groups in a water-free room are vertically arrayed at intervals, liquid inlets of the gate-type atomizing pipe groups in rows are communicated with a liquid inlet pipe through electromagnetic valves, a condensing liquid receiving bath with a high end and a low end is arranged below each atomizing pipe in the gate-type atomizing pipe groups in rows, the low end of each condensing liquid receiving bath is a guide outlet and communicated with a guide pipe, the bath surface of each condensing liquid receiving bath is a moisture absorbing metal surface, the back of each condensing liquid receiving bath is a conductive heating surface, a signal control end of each electromagnetic valve is connected with a signal end of a PLC (programmable logic controller), an inlet of the liquid inlet pipe is communicated with an outlet of a booster pump, an inlet of the booster pump is communicated with a dyeing tank through a pipeline, a atomizing curtain is vertically provided with upper cloth guide rollers and lower cloth guide rollers, middle shafts at the ends of the lower cloth guide rollers are driven to synchronously rotate by a motor through a transmission mechanism, and whether the booster pump and the motor are operated or not is controlled by the PLC. The zero-discharge atomizing continuous dyeing system has the advantages of fine dyeing effect, no feed liquid discharge and no environmental pollution.
