Abstract
The invention discloses a shell reuse type nuclear-grade high-efficiency air filter and belongs to the technical field of nuclear-grade air filters. According to the technical scheme, the shell reuse type nuclear-grade high-efficiency air filter is characterized by comprising a shell and a filter element arranged in the shell, the filter element and the shell are assembled in a screwed mode or a riveting mode or a bonding mode, the shell is a front-and-back through cavity formed by metal plates in a welded mode or a riveted mode, the filter element is composed of a clad material and a filter material, through holes distributed in parallel are formed in the front side and back side of the clad material respectively, and the filter material is bonded to the inner side, opposite to the through holes, of the clad material through sealing glue. Only the filter element needs to be replaced, the shell can continue to be used, the waste discharge of the filter is reduced, the filter element can be integrally compressed, dismounting work of waste filter elements is saved, the labor cost is reduced, and the human risk is avoided.
Description
Technical field
The invention belongs to core level air filter technical field, be specifically related to a kind of shell multiplexing type core level high efficiency particle air filter.
Background technology
For nuclear engineering, various nuclear facilities inevitably produce have radioactive refuse, for ensureing that radioactive substance is not to release in natural environment, it is necessary to reasonably radwaste is processed. At present, process the step of high efficiency particle air filter waste and old in nuclear engineering be still manually disassemble, superpressure packing, deep Tibetan are buried, the subject matter occurred among this has: the amount of waste that 1, filter produces is big; 2, waste and old filter manually disassemble relatively difficult, waste substantial amounts of manpower; 3, it is likely to human body is worked the mischief in the process manually disassembled by alpha-contamination waste and old filter; 4, the filter paper that the filter element of high efficiency particle air filter is made up of ultra-fine fibre glass silk; in the process manually disassembled; filter paper violent is torn, is shed; cause floating in working region having trickle glass fiber; if workman is improper to respiratory protection, these tiny glass fibre can be sucked by human body becomes healthy hidden danger. Therefore developing a kind of high efficiency particle air filter being made directly compression packing, for reducing core level refuse, reduce human cost, evade human risks, protection health has positive meaning.
Summary of the invention
It is an object of the invention to for reducing core level amount of waste, reducing human cost and evade human risks and devise a kind of shell multiplexing type core level high efficiency particle air filter.
The present invention adopts the following technical scheme that for achieving the above object, shell multiplexing type core level high efficiency particle air filter, it is characterized in that including shell and being arranged at the filter element of enclosure, by being spirally connected or riveting or bonding mode is assembled between filter element with shell, shell is to be welded by metallic plate or cavity that the front and back of riveting molding are through, filter element is by being coated with material and filtrate forms, the front and back being wherein coated with material are respectively provided on two sides with the through hole of parallel distribution, and the inner side of the cladding material relative with through hole is bonded with filtrate by fluid sealant.
It is preferred that, described cladding material is the cavity through with the left and right of flat board cladding material bonding forming by U-shaped cladding material, described filtrate is V-type folding ripple filtrate, and the V-type opening of this V-type folding ripple filtrate is relative with the through hole of the parallel distribution in both sides before and after cladding material.
It is preferred that, described U-shaped cladding material is arranged with the bridge plate for fastening filter element, this bridge plate is provided with and is coated with, with flat board, the screw that material is relative, flat board cladding material is provided with the pre-sunk screw relative with screw, bridge plate and flat board cladding material are by screw and pre-sunk screw assembly connection, bridge plate is provided with the silk hole relative with shell, and shell is provided with the installation screw relative with silk hole, and bridge plate by silk hole and installs screw assembly connection with shell.
It is preferred that, described U-shaped cladding material and flat board cladding material are metallic fiber sintered felt cladding material.
It is preferred that, the outside of described flat board cladding material is provided with the sealing gasket for installing sealing between filter and fixation means.
When the present invention compared with prior art has the advantages that filter replacement, it is only necessary to changing filter element, shell can be reused, and which reduces the waste discharge amount of filter; Filter element can carry out reduced overall, and what save waste and old filter disassembles work, reduces human cost, has evaded human risks.
