Technical background
Compressed air is produced people, various fields in life obtains using more and more widely, this is not only as a kind of power, with respect to kinds of drive such as mechanical, electric, hydraulic pressure, compressed air has its original advantage, is also depending on the progressive and perfect day by day of compressed air drying and purification techniques to a greater extent.
We know, contain a large amount of moisture content in the air, after air is compressed, relative humidity will become bigger (being in saturation state under most of situation), if do not take any measure, moisture wherein just enters pipeline along the line and all gas equipments, makes their corrosions, damage, in fact, the Wet Compression air of drying processing does not have Practical significance to a great extent.
Traditional freezing type drier comprises forecooler, evaporimeter and moisture trap, and forecooler is connected with evaporimeter, is connected with moisture trap by second connecting pipe by first connecting pipe, and evaporimeter is connected with moisture trap by the 3rd connecting pipe; Forecooler is provided with to be accepted from the air inlet of the Wet Compression air of air compressor machine and the gas outlet that will discharge through dried dry air; Moisture trap is provided with the discharge outlet that condensed water is discharged.
The technical conceive of traditional freezing type drier is: enter forecooler, evaporimeter, moisture trap in the drying machine successively from the Wet Compression air of air compressor machine, discharge through forecooler more afterwards.Air is cooled in evaporimeter, the water that exists with steam condition becomes liquid state at this, in moisture trap air and moisture from, water is discharged from outside the machine, the wet saturated air of low temperature carries out heat exchange with the high warm and humid saturated air that at first enters forecooler in forecooler, temperature raises and becomes the lower air of relative humidity, that is dry air is admitted to the downstream.
But forecooler, evaporimeter, the moisture trap of this traditional freezing type drier interconnect by steel pipe, occur the problem of pipeline rust easily, and the anvil cinder that constantly produces because of corrosion can stop up runner and pipe fitting at any time, threaten the operation of equipment; And owing to use pipeline to connect each parts, caused also that volume is big, Heavy Weight, heat exchanger effectiveness is low, energy consumption is high, the delivery air aridity is low shortcoming.
Summary of the invention
For overcoming the above-mentioned shortcoming of prior art, it is little to the invention provides a kind of volume, in light weight, and operation energy consumption is low, avoids taking place the integrated-type precooling evaporator of the freeze drier of corrosion.
The integrated-type precooling evaporator of freeze drier comprises the forecooler from the preliminary cooling of the wet saturated air of air compressor machine, the moisture trap that the evaporimeter and the condensed air of the air setting after the precooling carried out gas-water separation; Described forecooler is provided with the gas outlet of discharging dry air, be distributed with first fin that the forecooler inner chamber is separated into some air flow channels in the described forecooler, be provided with second fin that the evaporimeter inner chamber is separated into some condensation runners and refrigerant channel in the described evaporimeter;
It is characterized in that: described air flow channel comprises hot-air runner that is connected with air compressor machine and the cold air runner that is communicated with the outlet of described moisture trap, described hot-air runner and cold air runner are arranged at interval, the outlet of the hot-air runner of described forecooler is communicated with the import of the condensation runner of described evaporimeter, and the outlet of described condensation runner is communicated with the import of described moisture trap; Described condensation runner and refrigerant channel are provided with at interval.
Further, the adjacent setting of described forecooler and evaporimeter directly communicates.
Further, the adjacent setting of described evaporimeter and moisture trap directly communicates.
Further, the adjacent setting of described moisture trap and forecooler directly communicates.
Further, the integrated-type precooling evaporator of described freeze drier is characterized in that: described first, second fin is the plate fin structure of flat type or porous type.
Technical conceive of the present invention is: the wet saturated air from air compressor machine passes through the condensation runner that the hot-air runner enters into evaporimeter, and air is cooled in the condensation runner, and the water that exists with steam condition becomes aqueous water at this, with air separation; Condensed air enters into moisture trap, and moisture trap separates airborne moisture, obtains dry cold air; Cold air is discharged by the gas outlet by the cold air runner in the forecooler.
Through test, the present invention is used for treating capacity per minute 6M 3Drying machine, the complete machine gross weight is reduced to 110 kilograms by original 180 kilograms, and power consumption is reduced to 1.2 kilowatts by 1.5 kilowatts, and the dew point of giving vent to anger is reduced to-18 ℃ by-13 ℃.
The present invention is used for treating capacity per minute 8M 3Drying machine, the complete machine gross weight is reduced to 130 kilograms by original 210 kilograms, and power consumption is reduced to 1.5 kilowatts by 2 kilowatts, and the dew point of giving vent to anger is reduced to-17 ℃ by-12 ℃.
The present invention is used for treating capacity per minute 10M 3Drying machine, the complete machine gross weight is reduced to 170 kilograms by original 280 kilograms, and power consumption is reduced to 2 kilowatts by 2.5 kilowatts, and the dew point of giving vent to anger is reduced to-17 ℃ by-12 ℃.
Forecooler of the present invention, evaporimeter, moisture trap three are one, and no any pipeline links to each other between the three, and it is little, in light weight to have a volume, and operation energy consumption is low, avoids taking place the advantage of corrosion.
