Portion forms seven relatively independent cavitys, respectively spaced inlet chamber 5 and outlet chamber 6.When the air in ward is taken out
When taking, by air inlet pipe 2, in the inlet chamber 5 entered into casing 1, then it is forced to pass through from filter element 4, realizes net
Change, be finally discharged in escaping pipe 3 from outlet chamber 6, enter into elsewhere.
Reference picture 1, Fig. 2, offers six mounting grooves 7, the shape of mounting groove 7 and the shape of filter element 4 on casing 1
It is roughly the same, filter element 4 preferably with the interference fit of mounting groove 7.When filter element 4 when mounted, the installation in filter element 4
Frame 4-1 is directly plugged into mounting groove 7, installing frame 4-1 and the direct interference clamping of mounting groove 7, is set in the outside of installing frame 4-1
There is handle 4-11 to realize the force to installing frame 4-1 so that no matter in dismounting or installation, the easy stress of installing frame 4-1.
Reference picture 2 and Fig. 3, casing 1 are provided with a positioning rod 8, locating rod 8 and casing 1 in the side at the two ends of mounting groove 7
Between connection is realized by a bearing pin, while the lower surface of locating rod 8 is directly pushed against with the surface of casing 1；When installing frame 4-1 peaces
After being attached to mounting groove 7, be covered in a part for locating rod 8 on mounting groove 7 by rotational positioning bar 8, and the other end abuts to mounting groove
On the casing 1 of 7 opposite side so that installing frame 4-1 is spacing in mounting groove 7, secondary fixation is played, prevent installing frame 4-1
Come off from casing 1.
Filter element 4, reference picture 3 and Fig. 4, are provided with two-layer filter 4-2, respectively activated carbon mistake in installing frame 4-1
Filter screen 4-21 and high efficiency particulate air filter 4-22, both are separately fixed in installing frame 4-1, with dismounting and the casing 1 of installing frame 4-1
Realize fixed or separate.When air in ward passes through filter element 4, harmful substance can be remained in activated charcoal strainer 4-
On 21 and high efficiency particulate air filter 4-22, the purification to air is realized.
Fig. 1 is returned to, the side of air inlet pipe 2 includes four isocons 9, and opposite side is provided with four blast pipes 10, isocon 9
Front end is directly connected in the front end of inlet chamber 5, while blast pipe 10 can be connected from different pipelines so that when air from
After blast pipe 10 enters, concentrated in air inlet pipe 2, then again on four isocons 9 of runner, when entering into inlet chamber 5,
Due to the front end of inlet chamber 5 for closing is set so that air can only be forced to be flowed out from the filter element 4 of both sides, enter into side
On outlet chamber 6.
A valve 11 is provided with each blast pipe 10（The upper right side of reference picture 1）, valve 11 is ball valve, by valve
Door 11 can be opened and closed individually to the blast pipe 10, to realize individually controlling different pipeline situations.
With continued reference to Fig. 1, escaping pipe 3 is provided with the header 12 connected with outlet chamber 6 towards the outlet chamber 6 of casing 1, when
Air is entered into header 12 after entering into outlet chamber 6 from inlet chamber 5 by concentration, then passes through after being aggregated into escaping pipe 3
Airduct 13 discharges casing 1.
Two breather pipes 14 are also plugged with each inlet chamber 5 of casing 1（Reference picture 1）, breather pipe 14 and casing 1 it
Between by being welded and fixed, while the casing 1 of both sides is extended at the two ends of breather pipe 14, valve is provided with every breather pipe 14
11（The lower left of reference picture 1）, can equally realize individually controlling the break-make of breather pipe 14；Positioned at the breather pipe of the side of escaping pipe 3
14 connect on an air supply pipe 15, are supplied by 15 pairs of every breather pipes 14 of the air supply pipe.Breather pipe 14 is arranged on and leans on
The side of nearly filter 4-2 parts, thus after air enters into inlet chamber 5, the certain heat carried in air can be retained in logical
On tracheae 14, final heat is absorbed by the air in breather pipe 14, realizes the recovery to atmospheric heat.
The process of circulation of air：Air enters into air inlet pipe 2 from blast pipe 10, is entered into casing 1 by isocon 9 afterwards
Each inlet chamber 5, then entered into inlet chamber 5 by filter element 4, then enter into header 12 from inlet chamber 5,
Finally discharged from escaping pipe 3.Be arranged on a part of heat transfer in inlet chamber 5 during by inlet chamber 5 by air
Air in breather pipe 14, to improve the utilization rate of heat.
Embodiment two, reference picture 5：
A kind of fresh air exchange system, including a fresh air interchanger 16, fresh air interchanger 16 are a kind of to contain Total heat exchange core body
Fresh air, exhaust ventilation equipment.On the one hand the air of foul indoor is discharged outdoor, on the other hand outdoor ozone is passed through
After the processes such as sterilization, sterilization, filtering, then air is input to interior, advanced heat exchange is used during air exchange
Technology, so as to reach the function of energy regenerating, room air keeps fresh simultaneously to reduce indoor energy loss.
Fresh air exchange system also includes exhaust pipeline 17 and air draught pipeline 18, when both are connected with fresh air interchanger 16,
The purifier in an above-described embodiment one is also connected with, the air inlet pipe in the multiple pipelines in air draught pipeline 18 and purifier
Blast pipe 10 in 2 is connected so that air is before fresh air interchanger 16 is entered into, and air realization purification, and waste heat is preliminary
Conversion, at the same time the discharge pipe 13 on header 12 is communicated with the pipe 16-1 that calls prisoners in after letting them out for exercise in fresh air interchanger 16, finally by new
Wind interchanger 16 is discharged into air.
On breather pipe 14, the every other end of breather pipe 14 is connected in a supply pipeline communication in exhaust pipeline 17
On pipe 15, the air supply pipe 15 is connected with the air feed pipe 16-2 of fresh air interchanger 16, realizes air heat in purifier
Reuse, be ultimately discharged into in ward.
Specific embodiment is only explanation of the invention, and it is not limitation of the present invention, those skilled in the art
The modification without creative contribution can be made to the present embodiment as needed after this specification is read, but as long as in this hair
All protected by Patent Law in bright right.
