Energy-saving air conditioning cabinet using condensate water to purify air and purification method

The invention discloses an energy-saving air conditioning cabinet using condensate water to purify air and a purification method. A first conical separation plate and a second conical separation plate are symmetrically installed in a cabinet body. A mixing cavity A is formed between the first conical separation plate and an end plate of the cabinet body. A venturi scrubber is welded between the first conical separation plate and the second conical separation plate. A deflection plate demisting device, a surface cooling coil pipe device, a fan and a humidity sensor are sequentially arranged at the large end near the second conical separation plate. One end of a condensate water sucking pipe is connected with a liquid spraying hole in a venturi scrubber throat pipe, and the other end of the condensate water sucking pipe is connected with a condensate water outlet connector on the surface cooling coil pipe device. An electric adjustment valve is arranged on the condensate water sucking pipe and is in linkage wit
