The invention discloses an oil mist distributor. The oil mist distributor comprises an oil mist distributor body. An oil mist inlet, control switches and oil mist outlet connectors are arranged on the upper portion of the oil mist distributor body sequentially. An observation pipe is arranged in the middle of the oil mist distributor body. An oil discharging switch and an oil outlet connector are arranged on the lower portion of the oil mist distributor body in sequence. The oil mist inlet communicates with the control switches and the observation pipe. The control switches communicate with the corresponding oil mist outlet connectors. The oil mist outlet connectors communicate with the observation pipe, and the observation pipe communicates with the oil discharging switch. The oil mist inlet is used for receiving oil mist delivered by a pipeline and distributing the oil mist to condensation nozzles connected with the oil mist outlet connectors. The flow direction of the oil mist is changed by controlling the corresponding control switches, and the states of the condensation nozzles correspondingly connected with the oil mist outlet connectors are judged according to observed changes of the liquid level in the observation pipe.
