Description
Technical field
The utility model relates to a kind of gas-drying apparatus, particularly with the gas-drying apparatus of semiconductor refrigerating technology to compressed air cooling and drying.
Background technology
At present, the compressed air of medical air compressor mainly carries out drying (as the PB840 compressor, the Drager compressor) with molecular sieve.Molecular sieve is artificial synthetic crystal type aluminium silicate salt, adsorbs or repel the molecule of different material according to the size in its crystals hole, thereby is called " molecular sieve " visually.Molecular diameter can enter molecular sieve crystal less than the material of molecular sieve crystal hole diameter, thereby can be adsorbed, otherwise is ostracised.Because the diameter of water in air vapour molecule is less than molecular sieve crystal hole diameter, therefore steam is adsorbed to inside, molecular sieve hole, and molecular diameter then directly flows through from molecular sieve than big oxygen and the nitrogen of molecular sieve crystal hole diameter, thereby realizes the purpose of dry air.Price according to existing market valency molecule sieve drier is about 3000 yuan, therefore uses the compressed-air actuated cost of molecular sieve drying than higher.In addition, air compressor can only be put the object of length less than 400mm into, and reaches molecular sieve filter length that we filter requirement at present all greater than 450mm, is difficult to put in the air compressor.Based on above 2 points, we determine to design the semiconductor refrigerating drying proposal that is more suitable for air compressor.
The refrigeration drying principles is: compressed air when compression pump comes out temperature about 80 ℃, because under the constant situation of water in air vapor content, temperature and relative humidity are inversely proportional to, along with compressed air enters refrigerator, himself temperature constantly reduces the corresponding continuous rising of its relative humidity.When compressed-air actuated temperature drops to below the room temperature 5 ℃, steam vapour amount in the compressed air has arrived saturated under corresponding relative humidity, and redundant moisture is separated out from compressed air, when and then dried compressed-air actuated temperature is elevated to room temperature, this moment, compressed-air actuated relative humidity diminished, thereby reached the purpose with compressed air drying.
Semiconductor cooler is to use semi-conducting material to make cooler.See also Fig. 2, its refrigeration principle is: a N-type semiconductor element and a P-type semiconductor element are coupled to thermocouple with copper brace 14, connect dc source after, the transfer that will produce the temperature difference and heat in the joint.A superincumbent joint, the sense of current is n → p, temperature descends and absorbs heat and formation cold junction 13.And a following joint, the sense of current is p → n, temperature rising and heat release and form hot junction 15.Semiconductor thermocouple being together in series on circuit some by shown in Figure 3, then is in parallel aspect heat transfer, connect dc source after, be to be the hot junction below the cold junction above this thermoelectric pile, this has just constituted a common refrigerant thermopile.By means such as heat exchangers, constantly dispelled the heat in the hot junction of thermoelectric pile and keep certain temperature, the cold junction of thermoelectric pile is put into removes absorbing and cooling temperature in the working environment, the operation principle of Here it is semiconductor cooler.(this principle is found at Frenchman's Peltier in 1834.)
