The import of component is connected；
The recuperation of heat noise reduction component includes air-to-water heat exchanger, sound attenuator and acoustical panel, and the Air-Water heat is handed over
Parallel operation, which is surround, to be set in sound attenuator, and the inside of air-to-water heat exchanger forms static pressure chamber, and several acoustical panels layerings are set to empty
The top of air-water heat exchanger, and adjacent acoustical panel stagger setting, the bottom of sound attenuator and the exhaust duct of blower outlet are close
Envelope connection, and the exhaust duct is placed in below static pressure chamber.
Further, it is enclosed with silencing cotton on the sound attenuator and acoustical panel.
Further, the air-to-water heat exchanger is fin-tube type, concurrent flow, plate-fin or shell-and-plate structure.

The utility model has the advantages that：
The utility model is applied to have big flow, the air blower test occasion of high temperature of outgoing air, is wanted meeting emptying noise reduction
While asking, the heat in evacuation of air can be recycled.
Description of the drawings：
Fig. 1 is the utility model structure chart.
Fig. 2 is the utility model section view.
Specific implementation mode：
The utility model will be further described below with reference to the accompanying drawings.
Such as Fig. 1 and Fig. 2, the utility model discloses a kind of air-to-air energy recovery silencing means, and the device is for recycling air blower
The heat of hot-air is exported, including needs hot terminal 1, recuperation of heat noise reduction component 2, circulating pump 3 and pipeline, recuperation of heat noise reduction component 2
It is connected with the exhaust duct of blower outlet, the liquid outlet of recuperation of heat noise reduction component 2 passes through pipeline and the import phase for needing hot terminal 1
Even, the liquid feeding end of circulating pump 3 is connected by pipeline with the outlet of hot terminal 1 is needed, and the outlet end of circulating pump 3 is returned by pipeline and heat
The inlet for receiving noise reduction component 2 is connected.
Recuperation of heat noise reduction component 2 in the utility model includes air-to-water heat exchanger 22, sound attenuator 23 and acoustical panel
24, air-to-water heat exchanger 22, which is surround, to be set in sound attenuator 23, and the inside of air-to-water heat exchanger 22 forms static pressure chamber 21,
The layering of several acoustical panels 24 is set to the top of air-to-water heat exchanger 22, and 24 stagger setting of adjacent acoustical panel, sound attenuator 23
The exhaust duct of bottom and blower outlet is tightly connected, and the exhaust duct is placed in 21 lower section of static pressure chamber.
To ensure noise reduction, silencing cotton is enclosed on sound attenuator 23 and acoustical panel 24.
It needs to be connected with filter 4 on the pipeline between hot terminal 1 and circulating pump 3.
The hot-air of air blower discharge is sent into the ring that 23 inner airs of sound attenuator-water heat exchanger surrounds by exhaust duct
Shape space (static pressure chamber 21), into the interlayer space between air-to-water heat exchanger and cabinet wall after heat exchanger, then according to
It is secondary by multiple baffling silencers channels, finally arranged from the top of sound attenuator 23 to air.Hot water after heating then passes through circulating pump
Being sent to needs hot terminal, can be used for producing, live or low-temperature cogeneration, needs hot terminal that the regenerative apparatus such as water tank can also be arranged,
To ensure the stability of heat supply.
Air empties after flowing through heat exchanger cooling, reduces the thermal pollution to air, simultaneously because the air side of heat exchanger
The overbottom pressure of resistance, exhaust also accordingly declines.
The noise of air-line system mostlys come from flow area mutation and pipe friction, and wherein runner mutation noise is most again
Main noise source, the sound attenuator use baffling air duct, baffling in surrounding and sole arrangement silencing cotton, top outlet inlet position
Arrange that silencing cotton, babinet air inlet use divergent structure on wind path wall, since the wind collateral resistance of heat exchanger loses, exhaust, which flows through, changes
Hot device forms pressure difference, and static pressure chamber is formed in internal annular space.Compared to traditional structure forms, the sound attenuator is due to heat exchanger
Wind side pressure is dropped, the pressure difference smaller of static pressure chamber and external environment, in addition the barometric gradient that the flaring degree of lip-rounding is linear, the abrupt change of cross-section cause
Noise be greatly lowered.Meanwhile interior noise is by multiple baffling noise elimination wind conduits, backmost heavenwards, significantly reduces pair
The noise jamming of ground and ambient enviroment.
Air-to-water heat exchanger can be the structure types such as fin-tube type, concurrent flow, plate-fin, shell-and-plate, the wind of heat exchanger
Resistance can be arranged according to the outlet pressure of air blower, when the overbottom pressure of static pressure chamber is relatively low, can suitably adjust reduction spacing of fin, increase is changed
Hot device windage, vice versa.
Air-to-water heat exchanger can also be arranged as desired to L-type or U-shaped using being circular layout.According to actual process
Needs, water is also replaced by other media, such as glycol-cooled liquid, conduction oil medium.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
It for art personnel, can also make several improvements without departing from the principle of this utility model, these improvement also should be regarded as
The scope of protection of the utility model.
