Description
Technical field
The invention belongs to nuclear power plant's radioaerosol process field, be specifically related to a kind of filter element processed for nuclear power plant's radioaerosol.
Background technology
High efficiency particulate air filter processes in technique in nuclear power plant's radioaerosol important effect, gulf, field nuclear power station is provided with the high efficiency filter filter element of two Russia's designs and supply in primary Ioops storage tank emission control system, for purifying the radioaerosol in aerofluxus.Because active time is longer, current filter element filtering efficiency degradation, and domestic production producer conventional filter does not all have similar products, the present invention, by this high efficiency filter filter element being redesigned in filter paper material, filter cartridge construction, equipment size, filter efficiency etc., have developed a kind of new new filter element for nuclear power plant's radioaerosol processing filters.
Summary of the invention
The purpose of the present invention, not enough for prior art, it is provided that one is easy to operation, can effectively shorten the operating time changing filter, the filter element processed for nuclear power plant's radioaerosol of support personnel's safety.
The technical scheme is that
A kind of filter element processed for nuclear power plant's radioaerosol, including sealing gasket, upper end cover, connecting rod, outer protection network, efficient filter element, pre-filter cartridge, interior protection network, bottom end cover and discharge outlet；Described upper end cover is bolted with flange, between flange and upper end cover, is provided with sealing gasket；Six roots of sensation connecting rod it is provided with between described upper end cover and bottom end cover；Described pre-filter cartridge is hollow circular cylinder tubular, its inner core is provided with interior protection network, high efficiency filter core it is cased with outside described pre-filter cartridge, described high efficiency filter core is hollow circular cylinder tubular, being cased with outer protection network outside it, described outer protection network, efficient filter element, pre-filter cartridge, interior protection network are located between upper end cover and bottom end cover.
Described upper end cover centre position is provided with through hole；Described bottom end cover centre position is provided with discharge outlet.
Described outer protection network, efficient filter element, pre-filter cartridge, interior protection network upper end fixed by fluid sealant and upper end cover, lower end is fixed by fluid sealant and bottom end cover.
Described pre-filter cartridge adopts metal sintering felt.
Described efficient filter element and pre-filter cartridge surface filter paper adopt close pleat mode.
The invention has the beneficial effects as follows:
1. the present invention reduces filter element size, saves and installs working place, reduces waste throughput；
2. filter paper forming mode is changed to close pleat mode by original big folding length mode, can reach bigger filter paper area in same space, improves filter element entirety ventilation, extends filter element service life；
3. being additionally arranged pre-filtering section, pre-filtering section adopts stainless steel metal sintering felt material, can remove the large particulate matter in tail gas, extend integral device service life；
4. filter element overall weight alleviates, and is more convenient for installing and changes, and overall weight, less than 40kg, alleviates the working strength of field personnel；
5. it is connected by screw filter element body and vessel flange face, makes equipment seal relatively reliable.
Accompanying drawing explanation
Fig. 1 is the filter cartridge arrangement figure processed for nuclear power plant's radioaerosol；
Detailed description of the invention
The one present invention proposed below in conjunction with accompanying drawing and embodiment carries out further introducing:
A kind of filter element processed for nuclear power plant's radioaerosol, including sealing gasket 1, upper end cover 2, connecting rod 3, outer protection network 4, efficient filter element 5, pre-filter cartridge 6, interior protection network 7, bottom end cover 9 and discharge outlet 10；Described upper end cover 2 is bolted with flange, between flange and upper end cover 2, is provided with sealing gasket 1；It is provided with six roots of sensation connecting rod 3 between described upper end cover 2 and bottom end cover 9；Described pre-filter cartridge 6 is hollow circular cylinder tubular, its inner core is provided with interior protection network 7, it is cased with high efficiency filter core 5 outside described pre-filter cartridge 6, described high efficiency filter core 5 is hollow circular cylinder tubular, being cased with outer protection network 4 outside it, described outer protection network 4, efficient filter element 5, pre-filter cartridge 6, interior protection network 7 are located between upper end cover 2 and bottom end cover 9.
