Further, in order to make air generator be capable of providing the suitable air of pressure, the output end of the air accumulator is set
It is equipped with the pressure reducing valve of control gas pressure.
Further, it in order to eliminate the hydro carbons and carbon dioxide in air, is provided between the air accumulator and pressure reducing valve
For filtering the air filter of hydro carbons, carbon dioxide.
Detailed description of the invention
Fig. 1 is the work flow diagram of the specific embodiment of air generator.
Specific embodiment
Embodiments of the present invention are described further with reference to the accompanying drawing.
The specific embodiment of air generator of the invention, as shown in Figure 1, air generator includes sequentially connected air
Filter layer, air compressor, air dryer, two-position three-way valve, water filter I, water filter II, check valve, air accumulator, gas
Filter I, air filter II and pressure reducing valve.Water filter I is used in the present embodiment to the moisture coarse filtration in air, water filtering
Device II is to by way of the moisture refined filtration in the air of water filter I.Certainly in other embodiments, water filter I and water
Filter II can also be identical.
Air filtration layer is mounted at the air inlet of air compressor, for filtering air in impurity and dust, this reality
Applying the air filtration layer in example is that molecular sieve can also be not provided with air filtration layer certainly in other embodiments.
The air of air compressor output enters in air dryer, and air dryer is molecule membrane air dryer,
Special polymeric hollow film in molecule membrane air dryer only supplies water vapor permeation, when the higher compressed air of water content
When into special polymeric hollow film, a large amount of vapor and a small amount of compressed air penetrate special polymeric hollow film and are carried over air
Outside drier.Certainly in other embodiments, air dryer can also be not provided with and other devices is used to remove compressed air
In moisture, for example, gas-liquid separator.
In the present embodiment, reversal valve is two-position three-way valve, two-position three-way valve have working hole be connected to water filter and
The air inlet of air compressor connection and for connecting open to atmosphere discharge outlet, two-position three-way valve also have and make working hole and air inlet
The air inlet station of mouth connection and the discharge station for being connected to discharge outlet with working hole.Three mouths and two stations of two-position three-way valve
The needs of the present embodiment are just able to satisfy, two position four-way valve of analogy and two five-way valves etc. use two-position three-way valve using reversal valve
It reduces costs, certainly in other embodiments, reversal valve can also use other valve arrangements, for example, two position four-way valves etc..
The air of the endless white drying of molecule membrane air dryer output enters water filter I by two-position three-way valve
In water filter II, being equipped in water filter I and water filter II can be with the aluminium oxide loose particles of adsorption moisture, it is ensured that empty
Moisture in gas is completely removed.In the present embodiment, in order to which the moisture guaranteed in air is completely removed, two water filterings are set
Device.Certainly in other embodiments, one or three or more water filter also can be set.But a water is only set and is filtered
Device possibly can not completely remove the moisture in air.
The dry air that water filter II exports enters air accumulator by check valve.
Dry air in air accumulator filters out hydro carbons and titanium dioxide in air by air filter I and air filter II
Carbon.Filtered air by pressure reducing valve be adjusted to suitable pressure by air-out export give transformer oil chromatographic monitor
Device.In the present embodiment effective material of air filter I and air filter II be 13X-APG molecular sieve, the molecular sieve it is main
Chemical component is sodium X-type silicon aluminate crystal, can remove carbon dioxide and the hydrocarbons etc. in gas.
In the present embodiment, air filter is arranged by the output end in air accumulator and filters out hydro carbons and titanium dioxide in air
Carbon.Certainly it can also be not provided with air filter in other embodiments.
In the present embodiment, air is adjusted to by suitable pressure by setting pressure reducing valve, certainly in other embodiments
It can achieve the purpose that adjust air pressure using other structures, for example, regulating valve etc..
Course of work when air generator blowback is as follows:
When pressure reaches early warning value in air accumulator, air compressor stops working, and two-position three-way valve is switched to arrange by air inlet station
Station is put, the residual air in water filter I and water filter II is discharged by the discharge outlet of two-position three-way valve, since water filters
The adsorption capacity of pressure reduction in device I and water filter II, aluminium oxide loose particles weakens, and adsorbs in aluminium oxide loose particles
Water utilization pressure balance difference be detached from from aluminium oxide loose particles, the water being detached from from aluminium oxide loose particles is with blowback
Air pass through discharge outlet be discharged.
