Description
technical field:
The utility model relates to a kind of gas purifying equipment, particularly relates to a kind of being carried out by high temperature entrained by refrigerant and replaces the energy recovery freezing type drier reclaimed.
background technology:
Equipment for purifying air on existing market has a lot, and often use or common compressed air drier by cooler, heat exchanger, evaporimeter, compressor and air-cooled condenser connect to form, treat the compressed air inflow heat exchanger of moist high temperature, and carry out heat exchange with the cold air of discharging from evaporimeter, the temperature of the air entering vapor compression is reduced, compressed air after cooling flows into evaporimeter and refrigerant heat exchange, heat in compressed air is taken away by refrigerant, compressed air temperature declines rapidly, moisture in humid air is because the temperature that reaches capacity is condensed into water droplet rapidly, after steam-water separator is separated, condensed water is discharged from automatic drain valve.When equipment actual motion, refrigerant be in via compressor outlet flow to condenser pipeline on time carry a large amount of heat energy, its maximum temperature can reach 90 DEG C, in this partial heat energy main source board running, heat energy in compressed air is cemented out by refrigerant, the refrigerant carrying a large amount of heat energy is generally all lowered the temperature via condenser, and the energy of this part not only directly can be consumed, and too increases the load of condenser simultaneously.
summary of the invention:
The technical problem that the utility model solves is to provide a kind of reduction condenser duty, and a large amount of heat energy simultaneously produced refrigerant carry out the energy recovery freezing type drier of effective recycling.
The technical scheme in the invention for solving the technical problem is: a kind of energy recovery freezing type drier, comprise compressed air heat exchanger, be arranged on the precooler of compressed air heat exchanger porch, the evaporimeter be connected with compressed air heat exchanger outlet place, evaporator outlet is connected to compressor by coolant circulating system, steam-water separator, the entrance of described steam-water separator is connected respectively to compressed air heat exchanger and evaporimeter, described compressor is connected to the entrance of a condenser, the outlet of described condenser is connected to coolant circulating system by a heating power expansion valve, a heat reclaim unit is also connected between described compressor and condenser, this heat reclaim unit is made up of a container and the many water pipes be arranged in container, described water pipe is equidistantly laterally arranged in container, at the water outlet of described heat reclaim unit, one water regulating valve is set.
Further, in order to carry out drying process via the compressed-air actuated moisture after condenser, at described condenser, a device for drying and filtering will be set with being also connected between heating power expansion valve.
The beneficial effects of the utility model are: the technical program increases heat reclaim unit in drying machine; replace via the heat entrained by compressor refrigerant out; improve the water temperature in water pipe; not only reduce the heat entering refrigerant in condenser; simultaneously by unnecessary heat recovery; reduce the energy consumption of whole equipment use, and also play certain protective effect to flowing through the steel pipe carrying high temperature refrigerant, extend its service life.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the schematic diagram of the utility model structure.
In figure: 1, precooler 2, precooler heat radiation motor 3, condenser heat radiation motor 4, condenser 5, compressed air heat exchanger 6, delivery gauge 7, evaporimeter 8, steam-water separator 9, hot gas bypass valve 10, automatic drain valve 11, manually-operated gate 12, refrigerant low-pressure meter 13, refrigerant high and low voltage switch 14, refrigerant high pressure gauge 15, water regulating valve 16, heat reclaim unit 16-1, container 16-2, water pipe 17, heating power expansion valve 18, compressor 19, device for drying and filtering.
detailed description of the invention:
A kind of energy recovery freezing type drier as shown in Figure 1, comprise compressed air heat exchanger 5, be arranged on the precooler 1 of compressed air heat exchanger 5 porch, the evaporimeter 7 be connected with compressed air heat exchanger 5 exit, evaporimeter 7 exports and is connected to compressor 18 by coolant circulating system, steam-water separator 9, the entrance of described steam-water separator 9 is connected respectively to compressed air heat exchanger 5 and evaporimeter 7, described compressor 18 is connected to the entrance of a condenser 4, the outlet of described condenser 4 is connected to coolant circulating system by a heating power expansion valve 17, a heat reclaim unit 16 is also connected between described compressor 18 and condenser 4, this heat reclaim unit 16 is made up of a container 16-1 and the many water pipe 16-2 be arranged in container 16-1, described water pipe 16-2 is equidistantly laterally arranged in container 16-1, at the water outlet of described heat reclaim unit 16, a water regulating valve 15 is set, this water regulating valve 15 is for its recovered temperature of regulable control.
Further, in order to carry out drying process via the compressed-air actuated moisture after condenser 4, at described condenser 4, a device for drying and filtering 19 will be set with being also connected between heating power expansion valve 17.
After start, refrigerant compresses the steam being become HTHP from previous status through compressor 18, the steam of HTHP flows into condenser 4 and the time condensation by compressor 18, its heat is taken away rear temperature by heat reclaim unit 16 and is declined, the steam of HTHP is because condensation becomes the liquid of normal temperature high voltage, flow through heating power expansion valve 17 afterwards, because the throttling action pressure of heating power expansion valve 17 reduces, refrigerant is made to become the liquid of normal temperature and pressure, enter evaporimeter 7 afterwards, because the reduction of pressure, liquid refrigerants explosive evaporation becomes the gas of low-pressure low-temperature, a large amount of compressed-air actuated heat is absorbed during refrigerant evaporation, compressed-air actuated temperature is declined and reaches dry object, refrigerant after evaporation becomes the steam of low-temp low-pressure, flow back to from the air entry of compressor 18, next circulation is entered after being compressed by compressor 18.
The technical program increases heat reclaim unit in drying machine; replace via the heat entrained by compressor refrigerant out; improve the water temperature in water pipe; not only reduce the heat entering refrigerant in condenser; simultaneously by unnecessary heat recovery; reduce the energy consumption of whole equipment use, and also play certain protective effect to flowing through the steel pipe carrying high temperature refrigerant, extend its service life.
It is emphasized that, it is more than better implementation column of the present utility model, not any type of restriction is done in appearance to this utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
