The invention discloses a novel high-efficiency internal circulation reactor. The novel high-efficiency internal circulation reactor comprises a reactor body, a circulating pump and a pressure-stabilizing box, wherein the reactor body consists of a reactor upper part and a reactor lower part, which are connected with each other through a connecting flange; connecting devices are arranged on the side surfaces of the reactor upper part and the reactor lower part; the reactor upper part and the reactor lower part are respectively provided with a fixed block; the fixed blocks are connected with each other through an air cylinder; a feeding hole and an auxiliary material adding hole are formed in the top of the reactor upper part; a heating pipe is arranged in the reactor upper part; the pressure-stabilizing box is arranged below the heating pipe; one end of the pressure-stabilizing box is connected with the circulating pump through a circulating output pipeline; the circulating pump is connected with the reactor upper part; a filter screen is arranged on the reactor lower part; a liquid discharging hole is formed in the bottom of the reactor lower part. The novel high-efficiency internal circulation reactor is high in practicality, and convenient to install, maintain and operate; the reaction time of materials in the reactor is shortened; operation automation is realized, and thus the working efficiency is improved.

The invention discloses an internal circulation reactor for tritium removal of water. The internal circulation reactor comprises a top cover, an outer cylinder, a central area air inlet pipe, an annular gap area air inlet pope, a sintering plate, a flow guide cylinder, theta-ring filler, a tritium-containing water inlet pipe, a tritium-containing hydrogen exhaust pipe, an annular pipe type distributor and a low-tritium water outlet pipe. The top cover is arranged on the top of the outer cylinder, the annular pipe type distributor is located inside the outer cylinder, the tritium-containing water inlet pipe and the tritium-containing hydrogen exhaust pipe are both communicated with the outer cylinder, and the tritium-containing water inlet pipe is connected with the annular pipe type distributor. The bottom space in the outer cylinder is divided into a central area and an annular gap area by the glow guide cylinder, wherein the central area is communicated with the flow guide cylinder, and the annular gap area is communicated with the bottom of the outer cylinder. The sintering plate is fixed inside the outer cylinder. The central area and the annular gap area are filled with the theta-ring filler. The low-tritium water outlet pipe is communicated with the annular gap area. The internal circulation reactor has the advantages of being large in gas-liquid phase contact area and high in reaction efficiency, and tritium-containing water can flow in a fixed direction; meanwhile, the standing time of the liquid phase can be controlled, and thus the content of gas-phase tritium and the content of liquid-phase tritium after a reaction can be quickly and accurately controlled.
