Abstract
The utility model discloses an efficient freezing drier, which is used for the purification of compressed air and is provided with secondary filtration. The utility model is characterized in that the front of a heat exchanger is provided with a prefilter with a thick filter core, and an outlet of the prefilter is integrally combined with the heat exchanger; the outlet of an evaporator is provided with a fine filter core, and an inlet of the fine filter is integrally combined with the evaporator. Because the filter, the heat exchanger and the evaporator are combined together, the utility model has the advantages of low cost, small volume and convenient installation and transportation. Meanwhile, because low temperature is used for the filtration, the utility model has the advantages of high dehumidifying efficiency, etc.
Description
The utility model relates to gas purifying equipment, particularly the freezing type drier of purification of compressed air.
Compressed air because safe in utilization, control is convenient, cost is low, thereby is used as power source widely in fields such as pneumatic means, application, blowing, conveying.Containing a large amount of moisture content, dust, mist of oil in the compressed air without the purge drying processing, is a kind of inferior thick gas.Cause the pneumatic equipment fault easily with this thick gas source that is used as power, its efficient is reduced, the lost of life is until influencing product quality.In the compressed air purifier, what generally use is freezing type drier at present, but existing freezing type drier is single dehumidification function.In order to satisfy the compressed-air actuated purification requirement of high-cleanness, high, before and after freezing type drier, also must dispose fore filter and post-filter again, just common operation can reach the air cleaning purpose.
Adopt existing compressed air purification system, hold facility is many, and floor space is big, and pipeline is long, and efficient is low, Operation and Maintenance and transportation inconvenience etc.Therefore a kind of volume of needs is little, dehumidification rate is high, the compressed air cleaning equipment that function is many, easy to use.
The utility model purpose just provides a kind of improved compressed air freezing type drier, can obtain all very low purification of compressed air of impurity content such as moisture, dust, greasy dirt with a this freezing type drier.
Task of the present utility model is that following mode is finished:
High-efficiency freezing formula drying machine is made up of preposition forecooler, prefilter, heat exchanger, evaporimeter, fine filter, condenser, cold coal compressor etc., its characteristics are that the gas outlet of prefilter and the inlet of coarse gas of heat exchange are combined into one, and the air inlet of accurate filter and the gas outlet of evaporimeter are combined into one
Body, the gas outlet of accurate filter is connected with the purified gas of heat exchanger inlet.
Prefilter described in the utility model is made up of upper shell, lower shell, air inlet pipe, drainpipe, filter core, is characterized in that upper shell and heat exchanger are combined into one, and directly enters heat exchanger through the gas behind the filter element filtering; Lower shell connects airtight with upper shell mutually by flange, bolt.
Heat exchanger described in the utility model by thick gas import and export, purified gas import and export and cylindrical shell, heat exchanger tube form, be characterized in being that inlet of coarse gas and prefilter are combined into one, thick gas outlet is connected airtight with the air inlet of pipeline and evaporimeter, and purified gas import and fine filter connect airtight by pipeline.
Fine filter described in the utility model is made up of upper shell, lower shell, air inlet pipe, drainpipe, precision Filter element, be characterized in that upper shell and evaporimeter are combined into one, gas through evaporator cools directly enters fine filter, and connect airtight with the low temperature purification gas import of pipeline and heat exchanger its gas outlet; Lower shell connects airtight with upper shell mutually by flange, bolt.
The utility model owing to have the effect of cascade filtration, thereby does not need in addition configuration filter separately compared to the prior art again, owing to adopted filter at low temperature, has improved dehumidification rate, has also simultaneously that volume is little, a transportation, advantage such as convenient for installation and maintenance.
Below with reference to accompanying drawing structure of the present utility model is described in further detail.
At first 1. entering preposition forecooler by inlet without the damp and hot compressed air that purifies 2. cools off, 3. compressed air after the precooling enter prefilter through pipeline, the process filter core is most of aqueous water of elimination and greasy dirt 4., enters 5. further cooling of heat exchanger behind the dust of large-size.Enter evaporimeter then and 6. force cooling, make the vaporous water in the compressed air condense into aqueous water, the compressed air of low temperature directly enters fine filter, through the 8. clean compressed air of elimination aqueous water and greasy dirt and dust of filter core, is 7. exported by escape pipe by the heat exchanger back of 5. heating up again.
Condensed water in prefilter and the fine filter, greasy dirt, dust through blow-off pipe 9., 10. discharge, (12) are cold coal compressor in the accompanying drawing, (11) are condenser.
Claims (3)
1, a kind of high-efficiency freezing formula drying machine that is used for the compressed air purification, it comprises preposition forecooler, prefilter, heat exchanger, evaporimeter, fine filter, it is characterized in that prefilter is located at the thick gas air inlet of heat exchanger, fine filter is located at the evaporimeter gas outlet.
2, high-efficiency freezing formula drying machine according to claim 1 is characterized in that the upper shell gas outlet of prefilter directly is connected with the thick gas air inlet of heat exchanger, and the lower shell of prefilter closely is connected with upper shell by flange, sealing ring, sieve bolt.
