Abstract
The utility model discloses a hundred-stage fan filter unit which comprises a casing. An FFU efficient filter is arranged in the casing, a diffusing cover is arranged below the FFU efficient filter, a plurality of air return punch holes are formed in the two lateral faces of the casing, and a soft curtain is further hung on the periphery of the casing. According to the hundred-stage fan filter unit, the soft curtain is hung on the periphery of the casing of the hundred-stage fan filter unit and has a guide function on clean air blown out of the hundred-stage fan filter unit, avoids the situation that cleanness of space below the hundred-stage fan filter unit cannot meet the requirement as the circulating range of the clean air is small due to the fact that the clean air fast enters an air return opening.
Description
Technical field
The utility model has related to a kind of hundred grades of laminar flow hood, belongs to purification techniques field.
Background technology
The technical fields such as electronics, medicine, national defence, science and technology, bioengineering, in the subrange of requirement toilet, reach high cleanliness factor requirement, but common toilet cannot reach requirement conventionally, therefore need to be in hundred grades of laminar flow hood of clean indoor location, make the cleanliness factor of its lower side space reach high standard, meet specific demand.But the clean air of existing hundred grades of laminar flow hood in toilet, realize in circulation time, normally the scope of circulation is very little, the return air inlet that enters laminar flow hood that the clean air blowing out is very fast has affected the cleanliness factor of its lower side space.
Utility model content
The utility model provides a kind of hundred grades of laminar flow hood, makes the circulation fully in toilet of its clean air, guarantees the cleanliness factor of its lower side space.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
Hundred grades of laminar flow hood, comprise housing, and FFU high efficiency particulate air filter is installed in described housing, and the below of described FFU high efficiency particulate air filter is provided with diffusing cover, and two sides of described housing are provided with a plurality of return air punchings, and the surrounding of described housing is also hung with soft curtain.
Aforesaid a kind of hundred grades of laminar flow hood, is characterized in that: also comprise at least one return air column, the bottom of described return air column is provided with return air window, and top is connected with described housing by return air duct.
Aforesaid a kind of hundred grades of laminar flow hood, is characterized in that: the front of described housing is also provided with a differential pressure pickup.
Aforesaid a kind of hundred grades of laminar flow hood, is characterized in that: the side of described housing is still provided with the electrical control panel for air FFU high efficiency particulate air filter.
Aforesaid a kind of hundred grades of laminar flow hood, is characterized in that: described return air column is two, is respectively used to be arranged on the both sides of housing.
Aforesaid a kind of hundred grades of laminar flow hood, is characterized in that: described soft curtain is PVC material.
The beneficial effects of the utility model are: by the surrounding at hundred grades of laminar flow hood housings, hang soft curtain, the clean air that hundred grades of laminar flow hood are blown out plays the effect of guiding, avoid clean air very fast enter return air inlet, cause the range of DO of clean air too small, make the cleanliness factor of side space under hundred grades of laminar flow hood cannot reach requirement.
Accompanying drawing explanation
Fig. 1 is the side view of a kind of hundred grades of laminar flow hood of the utility model;
Fig. 2 is the front view of a kind of hundred grades of laminar flow hood of the utility model;
Fig. 3 is the structural representation of a kind of hundred grades of laminar flow hood with return air column of the utility model.
The specific embodiment
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figure 1-Figure 3, a kind of hundred grades of laminar flow hood, comprise housing 1, FFU high efficiency particulate air filter 2 is installed in described housing, the below of described FFU high efficiency particulate air filter 2 is provided with diffusing cover 5, two sides of described housing 1 are provided with a plurality of return air punchings 4, and the surrounding of described housing 1 is also hung with the soft curtain 6 of PVC material.The clean air that FFU high efficiency particulate air filter 2 is sent enters in toilet by diffuser plate 5 is rear uniformly, by the guide effect of soft curtain 6, avoid clean air to enter very soon return air punching 4, cause range of DO too small, make the cleanliness factor of side space under hundred grades of laminar flow hood cannot reach requirement.
Under the condition allowing at toilet's area, at least one return air column 9 can also be installed in toilet, the bottom of this return air column 9 is provided with return air window 10, and top is connected with described housing 1 by return air duct 11.Now, by return air punching 4 sealings, clean air that FFU high efficiency particulate air filter 2 the sends bottom by return air column 9 is provided with after return air window 10 enters return air column 9 and gets back in hundred grades of laminar flow hood, clean air can be circulated fully, guaranteed the cleanliness factor of its lower side space.
The front of housing 1 is also provided with a differential pressure pickup 8, for showing the resistance of FFU high efficiency particulate air filter 2, in its life-span for confirmation, changes in time.
The side of housing 1 is still provided with the electrical control panel 7 for air FFU high efficiency particulate air filter 2, and operating personnel can control the work of FFU high efficiency particulate air filter 2 as required.
Under the condition that wherein ， toilet area allows, return air column 9 can be two, is respectively used to be arranged on the both sides of housing 1, makes clean air more full and uniform in the circulation of toilet.
In sum, a kind of hundred grades of laminar flow hood that the utility model provides, make the circulation fully in toilet of its clean air, guarantee the cleanliness factor of its lower side space.
More than show and described basic principle of the present utility model, principal character and advantage.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is by appending claims and equivalent circle thereof.
