The specific embodiment
The integrated air dryer systems conjunction with figs. of the utility model description details is following:
The preferred embodiment of the integrated air dryer systems of the utility model such as Fig. 2 comprise to shown in Figure 8:
One refrigerant compression set 20 can compress refrigerant, and becomes the gaseous coolant of HTHP after refrigerant is compressed;
One refrigerant waste heat recovery plant 30 is connected the used heat of these refrigerant waste heat recovery plant 30 recyclable refrigerants after compression with this refrigerant compression set 20;
One condensing unit 40 is connected with this refrigerant waste heat recovery plant 30, the refrigerant that is flowed out by refrigerant waste heat recovery plant 30 is cooled off, and make refrigerant become the liquid refrigerants of high normal pressure and temperature;
One cold medium controller 50; Comprise a refrigerant filter 51 and an expansion valve 52; This refrigerant filter 51 is connected with this condensing unit 40; And this expansion valve 52 connects this refrigerant filter 51, and the refrigerant that is flowed out by condensing unit 40 filters and produce pressure drop and throttling through refrigerant filter 51 and this expansion valve 52, makes refrigerant become the liquid refrigerants of low-pressure low-temperature;
One vaporising device 60 is connected with this cold medium controller 50, the action that the refrigerant after handling through cold medium controller 50 is evaporated, and in the action of evaporation a large amount of absorption heat energy and produce refrigerating effect;
One heat exchange pre-cooler 70 is connected with this vaporising device 60;
One absorbed type drying unit 80; Comprise one first filter 81, one second filter 82, one first regenerator 83 and one second regenerator 84; This first filter 81 connects this vaporising device 60 and this second filter 82, and this second filter 82 connects this first regenerator 83 again, and this first regenerator 83 connects this heat exchange pre-cooler 70 again; This second regenerator 84 then connects this vaporising device 60, and ccontaining adsorbent is to carry out the absorption of moisture in this each regenerator 83,84; And
One heater 90 is connected between this refrigerant waste heat recovery plant 30 and this second regenerator 84.
More than be the structural relation of the integrated air dryer systems of the utility model, and when using, at first please cooperate and consult the sketch map that flows to for refrigerant shown in Figure 4; Refrigerant at first is collapsed into the gaseous coolant of HTHP by refrigerant compression set 20, then the gaseous coolant of HTHP flows to this refrigerant waste heat recovery plant 30, and then this refrigerant waste heat recovery plant 30 just can reclaim the used heat of refrigerant; Then refrigerant continues to flow to condensing unit 40, and condensing unit 40 becomes high temperature but the liquid refrigerants of middle temperature or normal temperature with the refrigerant cooling, then liquid refrigerants continue to flow through cold medium controller 50 and flow toward vaporising devices 60; 50 pairs of refrigerants of cold medium controller produce pressure drop and throttling, make refrigerant become the liquid refrigerants of low-pressure low-temperature, follow; The liquid refrigerants of low-pressure low-temperature flows to the action that vaporising device 60 evaporates; And in the action of evaporation a large amount of absorption heat energy and produce refrigerating effect, so far, accomplish complete freezing action; At last, refrigerant can flow back to the refrigerant compression set 20 freezing action next time that continues again;
Then; In the time will carrying out the action of gas drying; Please cooperate and consult shown in Figure 5ly, this heat exchange pre-cooler 70 of ambient atmos input produces the action of precoolings, and the air after the precooling then flows to vaporising device 60; Then vaporising device 60 produces cooling to air and makes the moisture ability of part in the air separated because of the refrigerating effect of refrigerant; This moment, the air via heat exchange pre-cooler 70 and vaporising device 60 produced preliminary drying effect, and then air produces the clean effect of filter through this first filter 81 and this second filter 82, and then air gets in this first regenerator 83; First regenerator 83 can produce the drying of the degree of depth to air, and dried gas just can be discharged via heat exchange pre-cooler 70 again and is provided with using;
The effect of this second regenerator 84 then is like Fig. 6, shown in 8, and heat exchange pre-cooler 70 partly gas is directed to this refrigerant waste heat recovery plant 30, and gas produces heat exchange through this refrigerant waste heat recovery plant 30; And be that gas is heated, then, the gas after heating continues through this heater 90; This heater 90 is the sense gasses temperature simultaneously, and when gas temperature no show still can make adsorbent reach the temperature of best regeneration effect, this heater 90 just can heat gas once more; And the temperature that gas is reached to make adsorbent reach best regeneration effect; When gas temperature reaches the temperature that can make adsorbent reach best regeneration effect, make gas flow to the regeneration action that second regenerator 84 carries out adsorbent again, so, supply gas temperature by this heater 90; The temperature that makes gas get into second regenerator 84 is to make adsorbent reach the temperature of best regeneration effect; The time that so just can reduce adsorbent reactivation, and can reach best regeneration effect, improve the adsorption efficiency of adsorbent; And can lower the burden of the each absorption of adsorbent, prolong the service life of adsorbent.
In addition; The utility model can be as shown in Figure 7 again in order to the motion flow that carries out adsorbent reactivation; It is can be with carrying out dried gas; By directly being directed to heater 90 between first regenerator 83 and the heat exchange pre-cooler 70, then heater 90 just can heat gas, and the gas after will heating again is directed to second regenerator 84 and carries out the regeneration of adsorbent; Then this flow process just need not passed through refrigerant waste heat recovery plant 30, uses as the usefulness that can't make the subsequent use renewable sources of energy of time spent when refrigerant waste heat recovery plant 30; Simultaneously, also can be as shown in Figure 8, also can make the gas of discharging directly be directed to heater 90 and heat and carry out follow-up adsorbent reactivation homing action by heat exchange pre-cooler 70.
