Description
Technical field
The utility model is related to pipe transportation technology field, especially a kind of double-deck heat exchanging air duct.
Background technology
At present, domestic foodstuff grain drying almost all is using coal-fired drying tower, and the heat produced by boiler fired coal passes through
Heat exchange is exchanged, and hot blast feeding drying tower, the horn shape box through being distributed in tower blows to cereal around, and the hot related Grain Dust of moisture passes through
Moisture exhausting port horn shape box is arranged to outside tower.Tower body chaotic state in which corrupt practices prevail is dried in drying course.The advantage of fire coal drying cereal is that drying tower is thrown
Money is small, and drying expense is low, has the disadvantage that the coal-fired great amount of carbon dioxide that produces pollutes air, boiler fired coal produces dust and drying tower row
Grain Dust produced by wet, has a strong impact on environment, and fire coal drying grain equipment is eliminated quickly.For heat pump grain heat-drying,
Cycling hot-blast heating is difficult to, because the damp-heat air of grain drying tower discharge, contains a large amount of dust, circulating air meeting
Heat pump heat exchanger fin is blocked, therefore, the heat that look in air draft that can only be helplessly is thrown away in vain.
Utility model content
The utility model offer is a kind of can be carried out reclaiming profit in drying course to the heat in the hot and humid gas of discharge
With, the air channel that is not easily blocked.
To reach above-mentioned purpose, using following technical scheme：
A kind of double-deck heat exchanging air duct, includes internal layer air channel and the outer layer air channel being enclosed on the internal layer air channel, described interior
The cylindrical spaces for being available for liquid to flow, the cylindrical spaces and the internal layer are formed between layer air channel and the outer layer air channel
Flowed respectively in air channel and be sealedly connected with a number of heat superconducting on hot fluid and cold fluid, the tube wall in the internal layer air channel
Pipe, the super heat-conductive pipe includes evaporator section, adiabatic section, condensation segment, and the evaporator section is arranged in cylindrical spaces, the condensation segment
It is arranged in internal layer air channel.
Medium evaporation and condensation in super heat-conductive pipe are that, by gravity operation, the super heat-conductive pipe is obliquely fixed on internal layer
On the tube wall in air channel, its angle of inclination is 30 °~70 °.
Further, it is provided with fin outside the condensation segment.Other end evaporator section is then light pipe, it is not easy to blocked.
As a preferred embodiment, the internal layer air channel and outer layer air channel are made up of galvanized iron sheet.
The super heat-conductive pipe is fixed on by way of welding on inner tube wind path wall.
The condensation segment and the evaporator section are equipped with fin.
The outside of the super heat-conductive pipe is copper pipe.
The equipment is by setting double-deck air channel structure, and the liquid temperature of inside and outside laminar flow is different, the evaporation of super heat-conductive pipe
Section plays a part of draw heat, by the exothermic effects of the condensation segment in the super heat-conductive pipe other end, is discharged through heat slave unit
Hot-fluid matter in heat transfer give in the liquid that newly sucks, especially effect is notable in the application of gas liquid.In addition, being
Directly by reclaiming heat in air channel, it is not easy to produce the phenomenon blocked.
Brief description of the drawings
Fig. 1 is the structural representation of double-deck heat exchanging air duct in the utility model；
Fig. 2 is the profile of double-deck heat exchanging air duct；
Fig. 3 is the structural representation of super heat-conductive pipe.
Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of double-deck heat exchanging air duct, includes inner tube air channel 1 and is enclosed on the internal layer wind
Outer layer air channel 2 on road 1, forms a tubular for being available for liquid to flow empty between the internal layer air channel 1 and the outer layer air channel 2
Between, flowed respectively in the cylindrical spaces and the internal layer air channel 1 on hot fluid and cold fluid, the tube wall in the internal layer air channel 1
A number of super heat-conductive pipe 3 is sealedly connected with, the super heat-conductive pipe 3 includes evaporator section 31, adiabatic section 32, condensation segment 33, institute
State evaporator section 31 to be arranged in cylindrical spaces, the condensation segment 33 is arranged in internal layer air channel 1.
Because the medium evaporation and condensation in super heat-conductive pipe are that, by gravity operation, the super heat-conductive pipe 3 is obliquely fixed
On the tube wall in internal layer air channel 1, its angle of inclination is 30 °~70 °.
The outside of condensation segment 33 is provided with fin 34.Other end evaporator section 31 is then light pipe, it is not easy to blocked.
The internal layer air channel 1 and outer layer air channel 2 are made up of galvanized iron sheet.
The super heat-conductive pipe 3 is fixed on by way of welding on the tube wall in internal layer air channel 1.
The condensation segment 33 and the evaporator section 31 are equipped with fin 34.
The outside of the super heat-conductive pipe 3 is copper pipe.
During work, the tubular that the hot and humid gas that drying room or drying tower are discharged are entered between internal layer air channel 1 and outer layer air channel 2
Circulated in space, the cold wind newly entered circulates out of internal layer air channel 1, the super heat-conductive pipe 3 welded on internal layer air channel 1 has quick
The effect of heat transfer, evaporator section 31 is in cylindrical spaces, the heat in hot and humid gas therein is just absorbed, in evaporator section
Working medium in 31 is activated immediately, and heat absorption vaporization becomes steam, and instant steam flows to adiabatic section 32, during arrival condensation segment 33 to the cold
Released to the cold wind newly entered and liquid is condensed into after heat, condensed fluid is back to evaporator section 31 through adiabatic section 32, heat transfer is high
Effect.Entered back into after cold wind is heated in the equipment such as dryer, saved the energy.
