Uranium dioxide hydrofluorination reactor in-built type gas filtering device

Abstract

The invention provides a uranium dioxide hydrofluorination reactor in-built type gas filtering device. The gas filtering device has a main structure of an inverted-cone shaped cone, the top of the cone is provided with an outlet pipe, and a reactor is arranged below the bottom of the cone; the bottom of the cone is connected with an upper flange, the top of the reactor is connected with a lower flange, and the connection of the cone and the reactor is achieved by connecting the upper flange and the lower flange; a positioning plate is arranged between the upper flange and the lower flange and in the bottom of the cone; a plurality of filter elements are uniformly distributed in positioning holes in the positioning plate; the lower ends of the plurality of filter elements are placed inside the reactor; evaginable edges of the upper ends of the plurality of filter elements are clamped on the positioning plate, and then are tightly pressed by a press plate arranged above the positioning plate. The device can effectively filter material dust entrained by tail gas and realizes a fact that a material is recycled and further participates in reaction in the reactor, and the filtering effect can reach more than or equal to 90%.

Description

technical field [0001] The invention relates to a uranium dioxide hydrofluorination reactor, in particular to a built-in gas filter device for the uranium dioxide hydrofluorination reactor. Background technique [0002] During the hydrofluorination reaction of uranium dioxide, the inside of the reactor body is in a positive pressure state. During the reaction, the excess gas flows to the next container through the outlet pipe. Due to the influence of the positive pressure in the reactor body, the reactor When the air flow in the furnace flows out, a large amount of mixed materials of uranium dioxide and uranium tetrafluoride will be entrained and removed at the same time. With the loss of energy, a large amount of dust material adheres to the subsequent pipelines, causing blockage of system pipelines and valves. And then affect the stable operation of the whole system of uranium dioxide hydrofluorination. Contents of the invention [0003] In view of the characteristics ...
