Device filter core, for purifying the radioaerosol in exhaust.Because active time is more long, current filter element filtering
Efficiency degradation, and domestic production producer conventional filter, without similar products, the present invention is by filter paper
The aspects such as material, filter cartridge construction, equipment size, filter efficiency are carried out again to the high efficiency filter filter element
Design, have developed a kind of new new filter core for nuclear power plant's radioaerosol processing filters.
The content of the invention
The purpose of the present invention, in view of the shortcomings of the prior art, providing one kind is easy to operation, can effectively shorten more
Change the operating time of filter, the filtering for nuclear power plant's radioaerosol treatment of support personnel's safety
Device flange connecting pipe filter core.
The technical scheme is that：
A kind of filter flange connecting pipe filter core for nuclear power plant's radioaerosol treatment, including flange connects
Pipe, upper end cover, support bar, outer protection network, efficient filter core, pre-filter cartridge, interior protection network, fluid sealant,
Bottom end cover and discharge outlet, wherein the flange connecting pipe is fixed on upper end cover by screw, the logical screw of flange is consolidated
Due to flange connecting pipe top；Six roots of sensation support bar, the pre-filtering are provided between the upper end cover and bottom end cover
Core is hollow circular cylinder tubular, and the interior protection network is located at pre-filter cartridge inboard cylinder wall surface, described efficient
Filtration core is placed on pre-filter cartridge outside；The high efficiency filter core is located between upper end cover and bottom end cover, described
Upper end cover center is provided with circular open, and be open, the circle concentric with pre-filter cartridge upper surface inner ring
Opening diameter is less than pre-filter cartridge internal diameter, and the bottom end cover center is provided with discharge outlet.
Sealing gasket A is provided between the flange connecting pipe and the flange of its upper end.
Sealing gasket B is provided between the flange connecting pipe and the upper end cover of its lower end.
The pre-filter cartridge uses metal sintering felt.
The efficient filter core and pre-filter cartridge surface filter paper use close pleat mode.
The beneficial effects of the invention are as follows：
1. filter element size has been reduced significantly, installation operation space has been saved, waste throughput has been reduced；
2. filter paper forming mode is changed to close pleat mode by original big folding length mode, and same space interior energy reaches
Bigger filter paper area, improves filter core entirety ventilation, extends filter element service life；
3. pre-filtering section is additionally arranged, and pre-filtering section sinters felt material, can remove tail gas using stainless steel metal
In large particulate matter, extend integral device service life；
4. filter element overall weight mitigates, and is more convenient for installing and changes, and overall weight is no more than 60kg,
Alleviate the working strength of field personnel；
5. installed by intervening flange connecting pipe, substitute mode changes, the design after improvement is changed more
Simply.
Brief description of the drawings
Fig. 1 is the filter flange connecting pipe filter core for nuclear power plant's radioaerosol treatment；
Specific embodiment
Below in conjunction with the accompanying drawings with embodiment to proposed by the present invention a kind of at nuclear power plant's radioaerosol
The filter flange connecting pipe filter core of reason is further introduced：
A kind of filter flange connecting pipe filter core for nuclear power plant's radioaerosol treatment, including flange connects
Pipe 2, upper end cover 4, support bar 5, outer protection network 6, efficient filter core 7, pre-filter cartridge 8, interior protection network
9th, fluid sealant 10, bottom end cover 11 and discharge outlet 12, wherein the flange connecting pipe 2 is fixed by screw
On end cap 4, the logical screw of flange is fixed on the top of flange connecting pipe 2；The upper end cover 4 and bottom end cover 11 it
Between be provided with six roots of sensation support bar 5, the pre-filter cartridge 8 is hollow circular cylinder tubular, the interior protection network 9
Located at the inboard cylinder wall surface of pre-filter cartridge 8, the high efficiency filter core 7 is placed on the outside of pre-filter cartridge 8；Institute
State high efficiency filter core 7 to be located between upper end cover 4 and bottom end cover 11, the center of the upper end cover 4 is provided with
Circular open, is open concentric with the upper surface inner ring of pre-filter cartridge 8, and the circular open diameter is less than pre- mistake
The internal diameter of filter core 8, the center of the bottom end cover 11 is provided with discharge outlet 12.
