Shown in Fig. 1-2, a kind of gas cooler such as compressed air cooler, the Media Interface Connector 9,10 and the tube side blowdown apparatus that comprise bearing shell body 1, three groups of finned tube heat-exchanging components 2,3,4, cooling medium turnover pipe, wherein finned tube heat-exchanging component 2,4 is 2 tube sides, and finned tube heat-exchanging component 3 is 4 tube sides.Described bearing shell body 1 is horizontal cylindrical pressure vessel, bears compressed-air actuated pressure, in the center of the two ends, the left and right sides of bearing shell body 1 end socket an interface is arranged respectively, and the left side is an intake interface 11, and the right side is the interface 12 of giving vent to anger, thereby compressed air is walked shell side; Described finned tube heat-exchanging component 2,3,4 is made up of fin heat exchange pipe 21, upper and lower tube sheet 24,25 and upper and lower tube side collection case 22,23, and fin heat exchange pipe 21 and upper and lower tube side collection case the 22, the 23rd are communicated with; Described upper perforated plate 24 is fixedlyed connected with the upper end of fin heat exchange pipe 21, the top of described bearing shell body 1 offers the rectangle interface 14 that cooperates with upper perforated plate 24, and the fin heat exchange pipe of described finned tube heat-exchanging component 2,3,4 removably hangs by upper perforated plate 24 and is installed on the rectangle interface 14; Described upward tube side collects case 22 and is arranged on the outside of bearing shell body 1, the top of upper perforated plate 24, removably be connected and fixed with upper perforated plate 24, so only tube side collection case 22 is gone up in dismounting, just can check the in-tube fouling situation of upper perforated plate 24 and fin heat exchange pipe 21, and clean, when pressure test, also can directly observe leakage situation, simple in structure, make things convenient for installing/dismounting; Be provided with a dividing plate 27 in the last tube side collection case 22 of described finned tube heat-exchanging component 2, with last tube side collection case 22 be divided into cooling medium turnover about two Room, its top is respectively equipped with the Media Interface Connector 9,10 that is connected with cooling medium turnover pipe; Be provided with two dividing plates 27 in the last tube side collection case of described finned tube heat-exchanging component 3, with its be divided into cooling medium turnover about two Room and middle medium back flow chamber, following tube side collection case has a dividing plate, two medium back flow chambers about being divided into; The periphery of described upper perforated plate 24 is provided with installing hole, is provided with the respective threads hole around the described rectangle interface 14; Described junction of going up tube side collection case 22 and upper perforated plate 24 is provided with rectangular flange 26, the periphery of described rectangular flange 26 is provided with and upper perforated plate installing hole, the corresponding through hole in rectangle interface thread hole, and described tube side collection case 22 and upper perforated plate 24, the rectangle interface 26 gone up removably is connected and fixed by bolt; Described finned tube heat-exchanging component 2,3,4 is separate be arrangeding in parallel, and its tube side can be walked the cooling medium in different temperatures and source; Perhaps described finned tube heat-exchanging component 2,3,4 connects by external pipe, and its tube side is walked identical cooling medium; Be provided with lower perforated plate 25 between described fin heat exchange pipe 21 and the following tube side collection case 23, described lower perforated plate 25 and fin heat exchange pipe 21, fixedly connected for sealing between the tube side collection case 23 down; The described bottom of tube side collection case 23 down is provided with the tube side blowdown apparatus, described tube side blowdown apparatus comprises the blow-off pipe 8 and tube side blowdown interface 6 of connection, offer shell side blowdown interface 7 in the bottom of bearing shell body 1 and stretch out for blow-off pipe 8, the medium of tube side and shell side all seals; The inwall of described bearing shell body 1 is provided with the resiliency supported 5 that offsets with following tube side collection case 23, the quality that makes bearing shell body 1 evenly bear finned tube heat-exchanging component 2,3,4, elastic bearing 5 also can absorb finned tube heat-exchanging component 2,3,4 because the distortion of expanding with heat and contract with cold and producing; One side of described bearing shell body 1 is provided with manhole 13, can enter bearing shell body 1 inside from manhole 13, checks fin heat exchange pipe 21 outer surfaces, bearing shell body 1 inner surface and finned tube heat-exchanging component 2,3,4 sealing condition all around.
During installation, with 2,3,4 liftings of finned tube heat-exchanging component, top is by the screwed hole of above-mentioned rectangle interface 14, the installing hole of upper perforated plate 24, the through hole bolting of last tube side collection case 22, following tube side collects case 23 bottoms and contacts with the elastic bearing 5 of installation in the bearing shell body 1, make bearing shell body 1 evenly bear the quality of finned tube heat-exchanging component 2,3,4, when tube side inspection or pressure testing, as long as turn bolt, after removing tube side collection case 22, use short bolting upper perforated plate 24, just can operate.
Operation principle is such: high temperature compressed air enters from interface 11, and through fin heat exchange pipe 21 outer surface gaps, with cooling water heat exchange in the pipe, wherein the cooling medium of three groups of finned tube heat-exchanging components 4,3,2 has nothing in common with each other, and temperature from high to low.Walk hot water about 90 ℃ as the tube side of finned tube heat-exchanging component 4, finned tube heat-exchanging component 3 tube sides are walked the middle warm water about 35 ℃, finned tube heat-exchanging component 2 tube sides are walked the water at low temperature about 10 ℃, the heat that hot water has absorbed high temperature air can be used as the thermal source or the process water of hot water lithium bromide refrigeration unit, middle warm water dispels the heat with cooling tower, and the water at low temperature source is handpiece Water Chilling Units; Three grades of cooling settings like this had both been utilized the waste heat of air compressor machine, made the water consumption of handpiece Water Chilling Units minimum again, increased income and decreased expenditure, and operating cost is minimum.
Compressed air is through three grades of coolings, and temperature is reduced to pressure leak source when following, has condensed water to separate out, and discharges by shell side blowdown interface 7.Because fin heat exchange pipe 21 outer gas side heat transfer coefficients are little more a lot of than water side in the pipe, so need to increase gas side heat transfer area,, use finned tube to make when air velocity descends Guan outer fin is exactly the area that increases, good turbulence effect is also arranged, so heat transfer efficiency height, drag losses are low.In order to prevent that air from walking short circuit, must seal (omitting among the figure) with thin plate in the periphery and the space between the inner walls of finned tube heat-exchanging component 2,3,4.
When cooler need clean inspection, connecting pipe on the dismountable cooling water turnover interface tube 9,10, dismantle the bolt on the rectangular flange 26 again, after removing tube side collection case 22, as seen the mouth of pipe of all fin heat exchange pipes 21 that gather on the upper perforated plate 24, check the internal incrustation situation, but mechanical chipping, and sewage, cast etc. can be discharged from blow-off pipe 8.If suspect fin heat exchange pipe 21 or upper and lower tube sheet 24,25 problem is arranged, allow be full of compressed air in the bearing shell body 1 after, available suds are directly checked.If still be difficult to pinpoint the problems, can directly hang out the back to finned tube heat-exchanging component 2,3,4 and check.
Present embodiment is for compressed air cold air device example, can also other gases of similar use such as nitrogen, oxygen etc., and principle is similar.
