Air compressor machine, the heat exchanger（1）Both ends pipeline parallel connection cold wind adjust branch（3）, the cold wind adjusting branch（3）On be provided with
Control valve（4）, the heat exchanger（1）Connect and be provided with thermometer on the pipeline of pocket type pulse valve for duster（5）.This practicality is new
Type is simple in structure, adjusts branch in the both ends parallel connection cold wind of heat exchanger, the cold wind of the hot wind and cold wind adjusting branch of heat exchanger mixes
Close to adjust to sack cleaner and suitably press air temperature, control is accurately measured by thermometer, can prevent that deduster condensation is rotten
Erosion, protection pulse valve film is without damage, extends the service life of sack cleaner.This application is disadvantageous in that, no
It can be used for the direct heat transfer of off-air, heat exchange efficiency is low.
Therefore, a kind of off-air is designed, dust can be filtered, ensures that the air of the air cleaning in heat exchange area changes
Hot device is with regard to necessary.
Utility model content
The utility model will overcome existing off-air Btu utilization difficult, the low deficiency of heat exchange efficiency, there is provided a kind of
Air heat exchanger, can be done directly the air heat-exchange of off-air, and heat exchange efficiency is high.
To achieve these goals, the utility model adopts the following technical solution.
A kind of air heat exchanger, including the protective housing of tubulose and the heat exchange tube core being located inside protective housing, protective shell
The one end of the both ends of body respectively with off-air import and export is connected, and the side wall of protective housing is equipped with inlet of cold air and hot-air goes out
Mouthful, the outer end of off-air import is equipped with dust filtration device, and dust filtration device includes the air inlet disk for being located at off-air inlet side, air inlet disk
For disc, the lower end of air inlet disk is equipped with dust-exhausting port.
Heat exchange tube core uses straight pipe, prevents heat exchanger tube in-core dust stratification, improves the heat exchange efficiency of air heat exchanger；Dust filtering fills
The dust of filtering off-air is put, reduces the Dust Capacity of heat exchanger tube in-core, improves the heat exchange efficiency of air heat exchanger, improves heat exchanger tube
The service life of core, movement outside of the air-flow along air inlet disk, due to the effect of centrifugal force, dust concentrates on the outer of air inlet disk
Side, drops out in the lower end of air inlet disk from dust-exhausting port, improves the filter effect of filtration apparatus, reduces the dust into heat exchanger tube in-core
Amount, improves the service life of heat exchange tube core.
Preferably, the internal diameter of air inlet disk cross section is equal with the internal diameter of protective housing cross section.It is convenient to complete protective shell
The sealing of body, prevents protective housing gas leakage, improves the heat exchange efficiency of air heat exchanger.
Preferably, being equipped with air inlet on the upside of the outer end of air inlet disk, air inlet disk is equipped with some close to the side of protective housing
Air holes is crossed, air holes is crossed and is equipped with dirt filtrating screen.Off-air flows to heat exchanger tube in-core via after dirt filtrating screen from air holes excessively, improves off-air
Dust removing effects.
Preferably, the downside of air inlet disk be equipped with the downward truncated cone-shaped of apex angle receive dirt groove, dust-exhausting port is positioned at receiving dirt groove
Bottom surface.Receive dirt groove can air heat exchanger using when play the role of accommodate dust, prevent dust from being raised in air inlet disk, carry
The Dust Capacity of high heat exchanger tube in-core, improves heat transfer efficiency.
It is uniformly arranged preferably, crossing air holes in air inlet disk on the side wall of protective housing one end.Under centrifugal force effect,
Heat exchanger tube in-core is flow to by crossing air holes with the off-air that large dust particle separates, advantageously reduces and enters heat exchanger tube in-core
Dust, while be conducive to off-air and uniform can must enter heat exchanger tube in-core from the port of heat exchange tube core.
The utility model has following usefulness：
1st, heat exchange tube core uses straight pipe, prevents heat exchanger tube in-core dust stratification, improves the heat exchange efficiency of air heat exchanger；
