A carbinol separation device in a device for producing fatty alcohol relates to a carbinol separation device in a device for producing fatty alcohol, which is mainly designed for solving the problems that when a carbinol distilling tower of an existing carbinol separation device is abruptly powered off, circulated cooling water is disconnected to cause that tower pressure is rapidly elevated. The carbinol separation device comprises a carbinol distilling tower, wherein a feeding inlet is arranged on the carbinol distilling tower, an air cooler is arranged on the upper portion of the carbinol distilling tower, the carbinol distilling tower is provided with a pipe line to connect with the air cooler, the air cooler is provided with a pipe line to downwards connect with a return tank and upwards connect with a secondary condenser, the secondary condenser is downwards provided with a pipe line to connect with the return tank, and is upwards connected with a blowdown pipe to discharge carbinol gas which is not con
