Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Compressed-air actuated saturation moisture content is relevant with temperature, and when temperature declines, water content also declines.Suppose that the pressure before entering drier is 0.7Mpa, temperature 40 DEG C, so the water content of per kilogram is about 5.7874 grams; Temperature drops to 3 DEG C, and the moisture tolerance of compressed air is about 0.5899/Kg.When one kilogram of compressed air drops to 3 DEG C from 40 DEG C, about there are 5.1984 grams of water recovery Cheng Shui.Refrigeration compressed air dryer is exactly that the condensed water cooled down is discharged by automatic drain valve by pressure-air cooling to about 3 DEG C, and compressed-air actuated water content is reduced greatly.
A kind of refrigeration compressed air dryer of the utility model, as shown in Figure 1, comprise cold medium compressor 3, air cooled chiller 4, precooling regenerator 5, evaporimeter 6, air cooled condenser 7, moisture trap 8, automatic drain valve 9, reservoir 10, air inlet 1 is positioned at air cooled chiller 4 side, air cooled chiller 4 is communicated with precooling regenerator 5, precooling regenerator 5 is communicated with evaporimeter 6, moisture trap 8 is communicated with evaporimeter 6 with precooling regenerator 5, automatic drain valve 9 is installed on below moisture trap 8, cold medium compressor 3, air cooled condenser 7, evaporimeter 6, reservoir 10 is connected successively by pipeline, form refrigerant circulation passage, it is characterized in that: also comprise water condenser 11, water condenser 11 is connected between cold medium compressor 3 and air cooled condenser 7, the condensed water of water condenser 11 comes from the isolated water of moisture trap, water condenser 11 is provided with discharge outlet 17.
Compressed air enters from air inlet 1 and to flow into the dry cold air that precooling regenerator 5 and evaporimeter 6 discharge after air cooled chiller 4 dispels the heat and carry out heat exchange, makes the compressed-air actuated temperature reduction entering evaporimeter 6; Compressed air after heat exchange flows into evaporimeter 6, liquid freon in evaporimeter 6 is by compressed air heating evaporation, simultaneously stability heat, heat in compressed air is taken away by freon, self cools rapidly, condensate moisture wherein becomes water droplet, and through moisture trap 8 and the air separation of High Rotation Speed, the water after separation flows out from automatic drain valve 9.Air after cooling is discharged from exhaust outlet 2 through the internal pipeline of precooling regenerator 5.
Precooling regenerator 5 is that the dry cold air utilizing evaporimeter 6 to discharge carries out precooling treatment to compressed air, if do not have precooling regenerator 5, high temperature compressed air directly enters evaporimeter 6, and refrigeration power consumption is approximately doubled.The energy has not only been saved in the setting of precooling regenerator 5, also makes dry air temperature be gone up, and makes discharge duct outer wall be unlikely temperature too low and occur dew condensation phenomenon.
The outer wall cover of precooling regenerator 5 and the inner copper pipe of evaporimeter 6 has aluminum fin-stock, can reduce the impact of air to copper pipe, avoid brass tube fracture while increasing heat exchange area.
Gaseous fluorine Leon after evaporation enters cold medium compressor 3 from evaporimeter 6 pipe outlet after reservoir 10 precipitation of liquid droplets and preheating, and cold medium compressor 3 exports the gaseous fluorine Leon of HTHP.The gaseous fluorine Leon of HTHP, successively through water condenser 11 and air cooled condenser 7, is condensed into the liquid freon of normal temperature high voltage.
High temperature full seal type reciprocating compressor during described cold medium compressor 3 adopts, compact conformation, volume are little, lightweight, noise is low, Energy Efficiency Ratio is high.
Water condenser 11 make use of the water that moisture separator 8 rotating separation goes out and carries out pre-cooled to the gaseous fluorine Leon that cold medium compressor 3 exports HTHP, under solving higher in some temperature, that dust is comparatively large, ventilation is not smooth environment, the problem that air cooled condenser 7 condensation effect is not good.Water condenser 11 is provided with discharge outlet 17, for getting rid of the water that temperature raises after heat exchange, the drainage speed of discharge outlet 17 can be regulated consistent with automatic drain valve 9, to ensure the circulation of cooling water in water condenser 11.
If the liquid freon that air cooled condenser 7 exports exceeds certain force value, be connected to super-pressure protection switch 15 deferred action on air cooled condenser 7 output channel, protect.Device for drying and filtering 14 plays the effect of impurity in filter liquid state freon.Heating power expansion valve 13 is throttle mechanism, and the liquid freon of normal temperature high voltage flows through heating power expansion valve 13, and because of its throttling action, the liquid freon being converted to Room-temperature low-pressure flows in the pipeline of evaporimeter 6, flows out evaporimeter 6, enter reservoir 10 after heat absorption evaporation.Pressure gauge is equipped with in the outlet of evaporimeter 6 gaseous fluorine Leon, and monitoring evaporimeter 6 exports the pressure of gaseous fluorine Leon.
When compressed air cools in evaporimeter 6, a large amount of condensate water is had to separate out.If freon evaporating temperature is too low, make evaporimeter 6 copper pipe surface temperature under load conditions lower than the freezing point of water, then condensate water will be frozen in evaporimeter 6, and blockade gas flow paths time serious, makes steam line paralyse.Cold medium compressor 3 export to export with air cooled condenser 7 between be connected hot gas bypass valve 16, the exit that hot gas bypass valve 16 pressure-measuring pipe is connected to evaporimeter 6 is monitored evaporating pressure.When evaporating pressure is lower than time to a certain degree, hot gas bypass valve 16 is opened automatically, and the high-temperature gas freon that cold medium compressor 3 exports directly enters evaporimeter 6, promotes evaporating temperature, avoids ice to block up phenomenon.
The above, be only specific embodiment of the utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
