Abstract
Provided is a refrigerated drier which comprises a case body. The case body is provided with a compressed air inlet, a compressed air outlet and a waterspout, the casing body is internally provided with an aluminum plate-fin heat exchanger which is formed by integrating a precooler and a vaporizer, the aluminum plate-fin heat exchanger is externally connected with a moisture trap via compressed air pipes, and the moisture trap is connected with an automatic drainer which is connected with the waterspout. The drier is not only compact in structure, but also high in heat changing efficiency.
Description
Technical field
The utility model relates to gas purifying equipment, refers in particular to a kind of freezing type drier of purification of compressed air.
Background technology
Compressed air is because safe in utilization, and control is convenient, and cost is low, thereby is used as power source widely in fields such as pneumatic means, application, blowing, conveying.Containing the moisture content about 30 grams in every cubic metre of damp and hot compressed air by air compressor output, but also contain dust and greasy dirt etc., is a kind of inferior thick gas.Cause the pneumatic equipment fault easily with this thick gas source that is used as power, make low, the lost of life of its efficient, until influencing product quality.In the compressed air purifier, what generally use is freezing type drier at present.For this reason, once open " a kind of frozen compressed air dryer " (ZL942430069 of Chinese patent, the day for announcing: August 9 nineteen ninety-five), it comprises the refrigerating plant of being with evaporimeter, the band inlet of coarse gas, the precooling heat interchanger of clarifier outlet, the precooling heat interchanger connects airtight by pipeline and evaporimeter, be characterized in being connected with between the low temperature purification compressed air inlet port of the low temperature compressed air outlet port of evaporimeter and precooling heat interchanger little water-separator of band micron order filter core, about 4% moisture that exist with the water droplet form in can elimination low temperature compressed air, the compressed air drying degree of output has only 750ppm, satisfies the gas equipment requirement fully." high-efficiency freezing formula drying machine " (ZL022304517, the day for announcing: on October 22nd, 2003), it has the high-efficiency freezing formula drying machine of cascade filtration, is characterized in being provided with the prefilter of being with coarse filter element before the heat exchanger, and the outlet and the heat exchanger of prefilter are combined as a whole; Be provided with fine filter with smart filter core at the evaporator outlet place, fine filter import and evaporimeter are combined as a whole, because filter and heat exchanger and evaporimeter are combined, have like this that cost is low, volume is little, installation and transportation are convenient, simultaneously owing to adopt filter at low temperature, dehumidification rate advantages of higher.But their heat exchange efficiencies are not very good.
The utility model content
The purpose of this utility model is to provide a kind of highly effective energy-conserving environmental-protecting type freezing type drier, and it is compact conformation not only, and the heat exchange efficiency height.
For achieving the above object, the solution that the utility model is taked is: a kind of freezing type drier, it comprises casing, this casing is provided with compressed air inlet, compressed air outlet and discharge outlet, casing is built-in with the aluminum plate-fin heat exchanger that forecooler and evaporimeter integrate, this aluminum plate-fin heat exchanger is by compressed air piping external gas separator, and moisture trap connects automatic water trap, the automatic water trap mouth of a river of running in.
The utility model is that the compressed air that utilizes refrigeration principle to make removes water correction plant.It adopts Refrigeration Technique that compressed air is forced cooling, and a large amount of aqueous vapor greasy dirts that compressed air is contained condense into drop, after moisture trap separates, outside automatic water trap discharge machine.Because the aluminum plate-fin heat exchanger that the utility model adopts forecooler and evaporimeter to integrate, compressed air enters aluminum plate-fin heat exchanger and cools off, cooled compressed air is through moisture trap elimination aqueous water, dust and greasy dirt etc., output after the compressed air of purification heats up through aluminum plate-fin heat exchanger again.Compressed air and the refrigerant contact area is big, the time is long, heat exchange is thorough, and cold-producing medium adopts the R134a environment friendly refrigerating fluid again, meets environment protection requirement; Wet, the dry-pressing air heat exchange that contracts is abundant, and compressed air is imported and exported and had a narrow range of temperature, and the chilling requirement of system is reduced significantly.Like this, it is about 25% that the power ratio known technology of refrigeration compressor reduces, and consumption of cooling-water reduces about 30% than known technology.Heat exchange area is big, and heat exchange efficiency improves more than 30% than known technology.Compact conformation reduces about 1/3 than existing drying machine size.Compressed air after the utility model is handled, its pressure leak source can reach 2 ℃～10 ℃, can satisfy most of industrial needs.
Description of drawings
Fig. 1 is the structural representation of present embodiment.
Among the figure: 1, casing, 2, compressed air inlet, 3, compressed air outlet, 4, discharge outlet, 5, aluminum plate-fin heat exchanger, 6, compressed air piping, 7, moisture trap, 8, control valve, 9, automatic water trap.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Referring to Fig. 1, a kind of freezing type drier, it comprises casing 1, this casing 1 is provided with compressed air inlet 2, compressed air outlet 3 and discharge outlet 4, casing 1 is built-in with the aluminum plate-fin heat exchanger 5 that forecooler and evaporimeter integrate, this aluminum plate-fin heat exchanger 5 is by compressed air piping 6 external gas separators 7, and moisture trap 7 connects automatic water trap 9, automatic water trap 9 mouth of a river 4 of running in.
Referring to Fig. 1, also be provided with control valve 8 between moisture trap 7 and the automatic water trap 9.
Because the present embodiment pipeline is provided with rationally, compared to the prior art, also have remarkable branch water, drain function.
