[0002] Crude oil is a mixture of various hydrocarbons. It is a viscous, dark brown liquid. It is very wasteful to use crude oil directly, so it is necessary to separate the components in crude oil, including crude oil pretreatment, atmospheric distillation and vacuum distillation. The pretreated crude oil is sent to the primary distillation tower of the atmospheric distillation unit after heating to distill out most of the light gasoline. The side line of the atmospheric tower enters the stripping tower, heated with water vapor or a reboiler, and the light components are evaporated to control the content of light components. Usually, the first side line is jet fuel or kerosene fraction, the second side line is light diesel fraction, and the third side line is heavy diesel or transformer oil fraction. The bottom product of the tower is atmospheric residue oil, which is heavy oil.
[0003] The heavy oil produced during the distillation separation process can be discharged through the discharge pipe. Due to the high density and viscosity of heavy oil, it will not only affect the fluidity inside the distillation tower, but also flow slowly, affecting the operating efficiency of the distillation process.

One end of the introduction pipe 23 is opposite to the shunt pipe 11. The introduction pipe 23 has a pipe passage 231 opposite to the discharge pipe 12, which can be transported from the shunt pipe 11 and the discharge pipe 12 to avoid affecting the fluidity inside the distillation tower and increase the flow rate, which can speed up the operation efficiency of the distillation process. When the piston head 211 moves, it can drive the connecting cross bar 25 to move, so that the sealing cover plate 26 moves along the surface of the introduction pipe 23, so that the sealing cover plate 26 blocks the entry hole 232, and repeats the movement to continuously accelerate the flow of the heavy oil in the introduction pipe 23.
