The invention discloses a combined type subway air purification handling unit. The combined type subway air purification handling unit comprises a shell, a filtering module, an automatic spraying purification module, a surface cooling module, a draught fan module and a controller module. The filtering module, the automatic spraying purification module, the surface cooling module and the draught fan module are sequentially arranged in the shell from the air inlet side to the air outlet side, aluminum alloy closed valves are arranged at the top and the side wall of the shell correspondingly, andthe aluminum alloy closed valves are located on the air inlet side of the shell; and the controller module is connected with the automatic spraying purification module and the draught fan module. According to the combined type subway air purification handling unit, the investment is low, the efficiency is high, power consumption is low, the operating cost is low, air supply is far, the air quantity is large, and the air supply amount per hour reaches 5000 m<3> or over 5000 m<3>; and the air purification quality is good, the cooling effect is obvious, timed starting-up and shutting-down and timed automatic washing can be conducted according to needs, and intelligent control is actually achieved.
