Description
Technical field
The present invention relates to a kind of compressed-air drier, especially a kind of freezing type high temperature compressed air drier.
Background technology
Frozen compressed air dryer is that the compressed air being made using principle refrigeration removes water correction plant, contain the compressed air of a large amount of saturation vapours by after cooling treatment from upstream pipe network, most water vapor condensations are into liquid water droplets, gone out after gas-water separation, the drying compressed air for being obtained can occasionally meet most industry needs.
Precooling regenerator and evaporator are the critical pieces of frozen compressed air dryer, generally use multichannel through type pipeline or the circulating pipeline of single channel, the defect such as the pipeline of above two form has cooling stroke short or cold medium flux is few.In high temperature environments or for the compressed air of higher temperature, condensation drying effect is not good enough.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of freezing type high temperature compressed air drier, pipeline and air direct in optimization design precooling regenerator and evaporator, solves the above problems.
In order to solve the above-mentioned technical problem, the technical scheme is that：
A kind of freezing type high temperature compressed air drier, including cold medium compressor, air cooled chiller, precooling regenerator, evaporator, air cooled condenser, moisture trap, automatic drain valve, reservoir, air inlet is located at air cooled chiller side, air cooled chiller connects precooling regenerator, precooling regenerator connects evaporator, moisture trap is connected with precooling regenerator and evaporator, automatic drain valve is installed on moisture trap lower section, cold medium compressor, air cooled condenser, evaporator, reservoir is sequentially connected by pipeline, form refrigerant circulation passage, it is characterized in that：The interior copper pipe by drying cold air of precooling regenerator is U-shaped, is inverted the flow direction that the guiding of H type baffle plate dries cold air.
Evaporator is divided into upper and lower two passages by lagging, after air enters into evaporator from precooling regenerator, upper channel and lower channel is passed sequentially through, subsequently into moisture trap.
Described cold medium compressor uses high temperature full seal type reciprocating compressor.
The outer wall of described precooling regenerator and evaporator inside copper pipe is cased with aluminum fin-stock.
The present invention by precooling regenerator by dry the copper pipe of cold air be set to it is U-shaped, set up in precooling regenerator inversion H type baffle plate, lagging is set up in evaporator, it is ensured that while drying cold air flows, increase cooling stroke, improve cooling effectiveness.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Specific embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
The saturation moisture content of compressed air is relevant with temperature, and during temperature drop, water content also declines.Assuming that into the pressure before drier be 0.7Mpa, 40 DEG C of temperature, then the water content of per kilogram is about 5.7874 grams；To 3 DEG C, the aqueous tolerance of compressed air is about 0.5899/Kg for temperature drop.One kilogram of compressed air from drop to 3 DEG C for 40 DEG C when, there are about 5.1984 grams of water recovery Cheng Shui.Refrigeration compressed air dryer is exactly that, by pressure-air cooling to about 3 DEG C, the condensed water for cooling down is discharged by automatic drain valve so that the water content of compressed air is substantially reduced.
A kind of freezing type high temperature compressed air drier, as shown in Figure 1, including cold medium compressor 3, air cooled chiller 4, precooling regenerator 5, evaporator 6, air cooled condenser 7, moisture trap 8, automatic drain valve 9, reservoir 10, air inlet 1 is located at the side of air cooled chiller 4, the connection precooling of air cooled chiller 4 regenerator 5, precooling regenerator 5 connects evaporator 6, moisture trap 8 is connected with precooling regenerator 5 and evaporator 6, automatic drain valve 9 is installed on the lower section of moisture trap 8, cold medium compressor 3, air cooled condenser 7, evaporator 6, reservoir 10 is sequentially connected by pipeline, form refrigerant circulation passage.
Compressed air flows into precooling regenerator 5 and carries out heat exchange with the cold air that dries of the discharge of evaporator 6 after being radiated into air cooled chiller 4 from air inlet 1 so that enter the temperature reduction of the compressed air of evaporator 6；Compressed air after heat exchange flows into evaporator 6, liquid freon in evaporator 6 is by compressed air heating evaporation, heat is absorbed simultaneously, heat in compressed air is taken away by freon, itself is cooled down rapidly, condensate moisture therein is separated through the moisture trap 8 of high speed rotation into water droplet with air, and the water after separation flows out from automatic drain valve 9.Air after cooling is discharged by the internal pipeline of precooling regenerator 5 from exhaust outlet 2.
Precooling regenerator 5 is that the cold air that dries discharged using evaporator 6 carries out precooling treatment to compressed air, if without precooling regenerator 5, high temperature compressed air is directly entered evaporator 6, refrigeration power consumption is increased about one times.The energy has not only been saved in the setting of precooling regenerator 5, also causes to dry air temperature and gone up so that it is too low and dew condensation phenomenon occur that discharge duct outer wall is not temperature.The present invention by precooling regenerator 5 by dry the copper pipe of cold air be set to it is U-shaped, while guarantee dries cold air flows, increase cooling stroke, improve cooling effectiveness, be lowered into the temperature of the compressed air of evaporator 6, be inverted H type baffle plate 11 play a part of guiding dry cold air stream to.
Precooling regenerator 5 is using U-tube road, change the flow direction of compressed air, therefore lagging 12 is set in evaporator 6,12 points by lagging of evaporator 6 is upper and lower two passages, after air enters into evaporator from precooling regenerator, upper channel and lower channel are passed sequentially through, the transformation of air flow is completed, while so that air contacts more abundant with refrigerant.
The outer wall of precooling regenerator 5 and the inside copper pipe of evaporator 6 is cased with aluminum fin-stock, can reduce impact of the air to copper pipe while heat exchange area is increased, it is to avoid brass tube fracture.
Gaseous state freon after evaporation enters cold medium compressor 3 after drop and preheating are separated through reservoir 10 from the pipe outlet of evaporator 6, and cold medium compressor 3 exports the gaseous state freon of HTHP.The gaseous state freon of HTHP is condensed into the liquid freon of normal temperature high voltage by air cooled condenser 7.
Described cold medium compressor 3 uses high temperature full seal type reciprocating compressor, and compact conformation, small volume, lightweight, noise are low, Energy Efficiency Ratio is high.
The above, specific embodiment only of the invention, but protection scope of the present invention is not limited thereto, and any change or replacement expected without creative work should all be included within the scope of the present invention.Therefore, protection scope of the present invention should be determined by the scope of protection defined in the claims.
