Description

Three machine integrated devices of freezing type compressed-air drier
Technical field
The utility model relates to the air drying equipment field, especially precooling, evaporation and gas-liquid separation integral type freezing type compressed-air drier.
Background technology
Air dryer is used for drying and purification of compressed air, makes subsequent compression air use equipment obtain the source of the gas of clean dried, is widely used in industrial production.The freezing type compressed-air drier is to utilize the refrigerant heat exchange that the compressed air of humidity is lowered the temperature, and oversaturated moisture content is separated out from air and separated, thereby realizes the drying of air, generally comprises forecooler, evaporimeter and three main parts of gas-liquid separator.
The forecooler 200 of prior art and the evaporimeter 300 general heat exchanger structures that adopt shell-tube type, as shown in Figure 1, warm-humid air 101 feeds the many heat exchanger tube that be arranged in parallel 204 inside from the warm-humid air inlet 201 of forecooler housing 203 1 sides, do heat exchange with the low temperature drying air 104 of housing inner chamber and realize precooling, air 102 concentrates on after the precooling air chamber 207 and enters evaporimeter 300 after the precooling; Low temperature drying air 104 feeds inner chamber from the cool air inlet 206 of forecooler housing 203 opposite sides, and complications are advanced under the effect of housing inner chamber polylith deflection plate 205, and discharging from dry air outlet 202 after the heat exchange is dry air 105.Entering after the precooling of evaporimeter 300 air 102 continues to walk around deflection plate 302 complications at evaporator shell 301 inner chambers and advances, and this moment heat exchanger tube 303 inner logical be refrigerant 106, freon etc. for example further cools off the back to air after the precooling 102 and forms Cryogenic air 103 and export gas-liquid separator 400 to from Cryogenic air outlet 304.
The gas-liquid separator 400 of prior art adopts the cyclone separating structure usually, as shown in Figure 2, housing 403 side wall upper part at columniform pressure vessel are provided with tangential air inlet pipe 401, the top is provided with gas outlet 402, the bottom is provided with discharge outlet 405, the Cryogenic air 103 that has liquid particles after the cooling tangentially pours from pressure vessel, in container, form the air-flow of rotation at a high speed, because gas is different with density of liquid, therefore discharge outlet 405 is flowed out in the heavier separated sinking of liquid, and the gaseous disk after the dehydration screws off and falls the back and rise along central authorities in the turning to back at the bottom awl end 404, discharge low temperature drying air 104 by center tube and gas outlet, enter the cool air inlet 206 of forecooler 200 again, warm-humid air 101 is carried out precooling.
Three main parts forecooler, evaporimeter and gas-liquid separators of the freezing type compressed-air drier of prior art are independent separately, and volume is very huge, production cost height, installation and maintenance complexity.The heat exchanger effectiveness of shell and tube exchanger structure is low, and the gap between dividing plate and the housing causes the air-flow short circuit easily, has had a strong impact on the efficient of heat exchange.The cyclone type gas-liquid separator is difficult for isolating the less mist pearl of quality in the air-flow, has also reduced dry efficient.
