In some narrow environments, cause installation to be not easy, so, how to lower ventilation unit length turn into research topic.For air-supply
For section, air return section, axial flow blower and reserved space for maintenance in it, do not possess the possibility of reduction unit length.For
For coil section, no matter bringing-up section or surface cooling section, to ensure temperature regulation effect, also do not possess and change coil pipe segment structure and then contracting
Subtract the possibility of ventilation blower group length, therefore, it is necessary to study it is a kind of simple in construction, it is easy to use, while filter effect is ensured
A kind of filtering segment structure of nuclear power plant nuclear island ventilation parameters unit of overall ventilation blower group length can be reduced.
Utility model content
The purpose of this utility model is to provide a kind of simple in construction, easy to use, energy while filter effect is ensured
Enough reduce a kind of filtering segment structure of nuclear power plant nuclear island ventilation parameters unit of overall ventilation blower group length.
To solve the above problems, the utility model provides a kind of fillter section knot of nuclear power plant nuclear island ventilation parameters unit
Structure, including bottom plate and machine unit shell, machine unit shell are fixed on bottom plate, and air supply section, air return section and disk are provided with machine unit shell
Pipeline section, wherein, fixed plate is set between coil section and air return section, and four sides of fixed plate are fixed by steady pin and machine unit shell to be connected
Connect, integrally formed cliche frame is provided with the middle part of fixed plate, if integrally formed on cliche frame be provided with dry lattice, grid
The integrally formed neck for being provided with strip of four edge, the side of cliche frame are equipped with high efficiency particulate air filter, high efficiency particulate air filter and grid
Match and connected and fixed by clamp in respective card slot, the opposite side of cliche frame is equipped with rough filter, poorly efficient filtering
Device is adjacent to together with again with high efficiency particulate air filter and fixed by pin.
Further, high efficiency particulate air filter is fiberglass products.
Further, high efficiency particulate air filter is cube shape structure, integrally formed thereon to be provided with some ripple type holes, height
Effect filter thickness is 30cm.
Further, rough filter is canvas or gauze or foliated glass cotton products, thickness 0.2-1cm.
Further scheme, the bottom of rough filter are provided with collection tray, and collection tray is fixed on cliche frame.For receiving
Collect the dust, rubbish etc. of bulky grain, these bulky grains hinder by rough filter and dropped in collection tray）.
To sum up, the utility model is simple in construction, easy to use, can reduce overall ventilation while filter effect is ensured
Unit length, it is specially：
The utility model changes rough filter in conventional art, has gap or space for maintenance among high efficiency particulate air filter
Set-up mode, supporting body is used as by cliche frame, by rough filter, high efficiency particulate air filter is individually positioned in the one of cliche frame
Side, makes rough filter, high efficiency particulate air filter closely,（It is to filter equivalent to the interval location of coil section and air return section
Section）, such a structure can effectively reduce unit length, need first to be loaded into high efficiency particulate air filter when installation, refill low
Filter is imitated, has fastener outside rough filter, high efficiency particulate air filter is fastened using rough filter.This structure,
Filter effect does not subtract and effectively shortens ventilation blower group length in 80-120cm.
