The invention belongs to the technical field of magnetic-confinement nuclear fusion. Magnetic-confinement nuclear fusion mainly comprises two kinds: one is an international thermonuclear fusion experiment reactor, wherein plasmas are sealed in an annular pipe with a radial gradient in a magnetic field, and ions easily run to a pipe wall; and the other is that plasmas are sealed in a straight fusion pipe with axisymmetric magnetic field distribution, ions cannot run to a pipe wall, and a magnetic plug is adopted, so difficult-to-block ions overflow from two ends. The magnetic plug has to be studied for many years before application. Therefore, the invention provides a magnetic confinement annular return pipe and a straight deuterium tritium (DT) fusion pipe as designed in an attached drawing of the specification. The magnetic confinement annular return pipe and the straight deuterium tritium fusion pipe consist of a straight fusion pipe 10 positioned in a superconducting coil 17, and annular return pipes 7 and 20 with two ends positioned in superconducting coils 5 and 18. Deuterium ions, tritium ions and electrons are respectively injected into the left and right ends. Under the constraint of a magnetic field, ions and electrons flow out from the two ends of the fusion pipe, pass through the annular return pipe and then flow into the fusion pipe again. In the straight fusion pipe, ions with opposite movement directions collide with each other, and hundreds of thousands of watts of deuterium-tritium fusion power is generated per cubic centimeter. The magnetic confinement annular return pipe and the straight deuterium tritium fusion pipe can be applied in several years.
