摘要:
The object of the invention is to provide a device which can, with high efficiency, polish and clean the inner surface of a pipe, dry the wet inner surface of the pipe, and perform coating, wherein the device does not require a large pump or a large motive force, and does not require a blast hose or a suction hose. More specifically, provided is an intra-pipe turbine blast system that moves along the inside of a pipe and performs work by spraying a fluid toward the inside of the pipe, wherein: a gas injected from a fluid supply device to the upstream-side end inside the pipe imparts speed to a mixed phase fluid consisting of a liquid and solid particles which are likewise injected into the pipe; the flow speed of the mixed phase fluid is set to 3 m per second which is the critical speed at which solid particles can float without precipitating in the liquid, and as a result of such setting, there is a great effect on reducing the energy required for causing the mixed phase fluid to move; and the mixed phase fluid with such setting is injected at a high speed from a rotation nozzle of a turbine crawler which moves inside the pipe, thereby polishing the inner surface of the pipe, and following the polishing work, the turbine crawler can clean, dry and coat the inner surface of the pipe.
