Description
Technical field
The technology belongs to filter device field, and in particular to a kind of filtering for remote disassembling in high-level cell
Device.
Background technology
Element shears hot cell using the pre- exhaust filtering system of push-in type set on wall behind hot cell, and spent fuel element is put
Penetrating property activity is very high and a large amount of radioactive dusts are generated in shear history so that cartridge is carrying out hot cell gas filtration
Cheng Zhong, dosage rate raising are very fast.It is very high for filter requirement on machining accuracy since pre- exhaust-air filter push-in channel is long,
And only by-pass filtration, filter area is smaller, filter efficiency is low, it is impossible to meet technological requirement.And operating personnel were carrying out
Filter core can not be observed in place when replacing, and there are blind operations, easily lead to position inaccurate, and exhausting duct is made to be led directly to hot cell so that
There is part radioactivity air-flow to be filtered without filter core, the air draft of pre- air exhausting device is directly entered from the gap between contact surface
Mouthful, cause the middle and high effect cartridge dosage in follow-up exhaust Air Cleaning case exceeded, need to frequently replace；Influence hot cell exhaust gas purification
System normal operation causes process system to stop and generate a large amount of height and puts (or α) waste, increases the processing load of solid waste
With operating personnel's radioactive dose.
Therefore need to design one kind suitable for post processing working environment, that is, hot dust atmosphere, and purification efficiency is high,
The filter device of favorable sealing property, service life length.
Invention content
It is an object of the invention to：A kind of filter device for remote disassembling in high-level cell is provided, is had
It is simple in structure, purification efficiency is high, treating capacity is big and the features such as favorable sealing property.
Technical scheme is as follows：A kind of filter device for remote disassembling in high-level cell, including
Filter B, filter A, filter B and filter A are connected by air hose between grade；The connection of air hose and filter B between its middle rank
There are water inlet pipe, annular water seal cavity B, annular water seal cavity B connections overflow pipe B in place, and filter B is mounted among filter housings B,
The top end cap water seal cavity of filter B；End cap water seal overflow pipe；End cap water seal water inlet pipe, wherein end cap water seal cavity are around filtering
Device B tops one are enclosed, filter B upper part mushroom head B, mushroom head B top for end cap, by end cap by filter B top
Portion covers；
The connecting portion of air hose and filter A have overflow pipe A, annular water seal cavity A, annular water seal cavity A connections water inlet pipe between grade
The lower end of A, filter A are filter lower face, and filter material is installed in the middle part of filter A, and the top of filter A is filter upper end
Face, the upper part of filter A is mushroom head A.
Air hose is fixed by base fixing device and ground between the grade.
When needing replacing filter B or filter A, mushroom head is connected using Automatic hook block, thus by filter B or filtering
Device A is sling, and filter B or filter A are positioned on the positioning sleeve of ground after slinging.
Suppression shake pouring weight is placed on the filter upper surface.
The remarkable result of the present invention is：After completing filter device items improvement, carry out plus water water seal, development are filtered
Device differential pressure verification test, primary filter differential pressure is using the impulse between hot cell negative pressure measurement pipe and first medium effeciency filter on air hose
Pipe, which combines, to be measured, and medium effeciency filter pressure difference is used between core grade high efficiency particulate air filter import pressure guiding pipe and first medium effeciency filter on air hose
Pressure guiding pipe, which combines, to be measured, and the pressure measured everywhere is with R02 hot cells negative pressure and the import wind pressure ratio of purifying box to can accurately judge
The actual resistance of four filter cores in work.And consider to replace at a distance using power hand, manipulator verification cartridge
(demolition, installation) operating characteristics opens water seal valve water filling verification filter sealing performance.
Show that the equipment meets the technical requirement of hot cell radioactive dust place air draft through operation after a period of time,
Favorable sealing property, filter effect is good, by power hand and the compounding practice of manipulator, verifies first, medium effeciency filter core just
In replacing at a distance, medium effeciency filter housing in (demolition, installation) operation and replacement process is solid and reliable..
