Description

A kind of leaching device for uranium-bearing waste residue
Technical field
The invention belongs to nuclear fuel cycle technologies, and in particular to a kind of leaching device for uranium-bearing waste residue.
Background technology
During nuclear fuel processing and manufacturing, uranium-bearing waste residue is inevitably resulted from, in Spent Radioactive water process, radioactivity During combustible waste burns, radioactivity cartridge is reorganized and outfit etc., uranium-bearing waste residue can be also generated, the uranium in these uranium-bearing waste residues contains Amount is very high, is a big environmental problem if do not handled, there is also criticality safety risks, handle and extract uranium therein not Only huge social benefit also has very high economic value.It extracts uranium therein and is necessarily required to acidleach process, correspondingly Need leaching device.
Uranium-bearing waste residue is divided into two classes, and one kind is the waste residue containing natural uranium, and another kind of is the waste residue containing enriched uranium.Containing natural uranium Waste residue mainly consider to leach effect, radiation protection and leakproofness, the problem of without the concern for criticality safety, leaching device not by The influence of size, shape, volume can be made very big, select cylindrical tank diameter general in the market, the material selected is done The leakproofness of good equipment.Waste residue leaching device containing enriched uranium will be considered outside above-mentioned factor, it is contemplated that critical peace Full problem, i.e. leaching device need safe by geometry, and the shape and size of device are strictly limited, and the requirement of device is high very much.Cause This, the waste residue leaching device containing enriched uranium can be common to this two classes waste residue.This patent mainly discusses the waste residue leaching containing enriched uranium Take device.
Existing leaching device is all cylindrical, and device internal diameter is less than 219mm, the high about 4000mm or so of device, due to dress It puts elongated, is not equipped with mechanical agitation, pressure sky is usually passed through in bottom and carries out auxiliary stirring, charge door is located at the top of cylinder Portion, top are docked with charging basket, are needed manually to splicing bucket, there is electric heater unit in the lower half of cylinder, it is ensured that temperature control exists (70~90) DEG C, the exhaust gas for reacting generation is taken away by vacuum, and after having reacted, leaching liquid and insoluble slag are pumped to next hilllock together Position.There are probelem in two aspects for existing device, first, the problem of stirring, presses the energy force difference of empty stirring, and not tolerant is more in device, After being deposited on bottom, mixing effect is poor;In leaching process, nitric acid and material reaction can generate big nitrogen carrier of oxygen, add in pressure Sky then increases exhausted air quantity, has aggravated the burden of washing tail gas, and easily emits slot.Second is that needing to intervene manually, operating personnel need Frequently charging basket with leaching device to be docked, disconnected, radioactivity material is caused to be exposed in environment, influence the body of operating personnel Health, it is also bad to environment, it is unsatisfactory for the requirement that country and industry operate radioactive substance.
Invention content
The purpose of the present invention is to provide a kind of leaching devices for uranium-bearing waste residue, can realize the automation of charging With requirement completely closed, that satisfaction country operates radioactive substance with industry.
Technical scheme is as follows:
A kind of leaching device for uranium-bearing waste residue, the buffering area of charging zone, middle part and the heating of lower end including upper end Reaction zone, the charging zone include the vacuum feeder, caching feed bin and gas separators of connection, and vacuum feeder is located at top Portion, interposition caching feed bin are set below vacuum feeder, and gas separators are set below caching feed bin;The gas separators For a segment pipe, connect with the discharge port of caching feed bin lower end, set on pipeline there are two Pneumatic butterfly valve, two Pneumatic butterfly valves it Between be equipped with gas feed, gas feed connection nitrogen pipeline;The buffering area includes the cylindrical glass tube of connection, bourdon tube Cylinder and circular spray tube;The bourdon tube cylinder is spring type cylinder made of elastic material, and upper end is equipped with tail gas Outlet, bourdon tube cylinder upper end are connect with gas separators lower port so that the two communicates;The circular spray tube is located at Below bourdon tube cylinder, filling opening is processed on side wall;The cylindrical glass tube is located at below circular spray tube;It is described Heating reaction zone be located at bottom, including heated cylinder and canned motor pump;The heated cylinder lower end be equipped with sewage draining exit, Pressure is empty to add in mouth and liquid outlet, and the pressure sky adds in mouth connection pressure vacant duct, and liquid outlet connection canned motor pump is described The outlet of canned motor pump sets threeway and connects two pipelines, and a pipeline connects subsequent processing, and another pipeline connects heated cylinder.
