The invention relates to a 
pipe plug removal device and a plug removal method, in particular to a 
crude oil coagulated 
pipe plug removal device and a plug removal method with the plug removal device. The problems that existing 
pipe coagulated pipe plug removal is high in cost, and environmental 
pollution is easily caused are solved. The 
crude oil coagulated pipe plug removal device is characterized in that a liquid inlet pipe, a liquid outlet pipe and a stirrer transmission shaft are installed in a sleeve in a sleeved mode, the liquid inlet pipe is connected with a 
liquid injection pump, the stirrer transmission shaft is connected with a motor, the liquid outlet pipe is connected with a liquid 
infusion pump, and the stirrer transmission shaft is connected with a stirring head of a stirrer. The plug removal method includes the steps of judging the position of a coagulated pipe section, determining an available opening of the pipe, inserting the sleeve into the available opening, and enabling the stirring head to be in contact with coagulated 
crude oil; starting the motor to drive the transmission shaft to drive the stirring head to 
crash the coagulated crude oil; starting the 
liquid injection pump to pump plug removal liquid into the coagulated crude oil section; starting the liquid 
infusion pump to pump out mixing liquid; when plug removal is finished, shutting down the 
liquid injection pump and the motor, then shutting down the liquid 
infusion pump, pulling out the sleeve, recovering the original appearance of the pipe, and finishing plug removal. The device and method are used for crude oil coagulated pipe plug removal.
