Using being adhesively fixed between road and strip of paper used for sealing 13, this assembly method is lower compared to traditional welding manner cost, processes also more
It is convenient；The outside of plate wing heat-exchanging component is compressed with frame 14, and frame 14 adds the form of screw rod using channel steel, to guarantee between plate
It is tightly compacted, the nut on screw rod is screwed, is exactly fin plate 11, the application compression prestressing force of plate 23 of heat exchanging component, to subtract
Both small heat transfer contact thermal resistance.
The aerial cooler 2 of the present embodiment is made of three groups of heat exchange units 20, length of the heat exchange unit 20 along shell 40
Direction arrangement, every group of heat exchange unit 20 include fin heat exchange pipe 21, upper tube box 22 and the lower tube box 23 of tubular, fin heat exchange pipe 21
It is vertically to the length direction setting of shell 40, upper tube box 22 and lower tube box 23 symmetrically cover the upper and lower ends for being located at fin heat exchange pipe 21
Opening, upper tube box 22 and lower tube box 23 stretch out outside shell 40 respectively, are removably covered with and are welded with into water on upper tube box 22
Adapter tube 241 and the upper cover plate of water outlet pipe 242 24, the lower end of lower tube box 23, which is removably covered with, is welded with blowdown connection 251
Lower cover plate 25；Upper tube box 22 is rectangular tube 222, the rectangle tube sheet 221, rectangular flange by being welded on fin heat exchange pipe 21
223 and tube side demarcation plate 224 form, rectangle tube sheet 221 is weldingly fixed in rectangular tube 222, the plane of rectangle tube sheet 221
Length and width size is both less than 21 diameter of fin heat exchange pipe, and thickness is between 12~20mm, the structure and upper tube box 22 of lower tube box 23
It is essentially identical, the difference is that 224 few one pieces of tube side demarcation plate of the tube side demarcation plate 224 of lower tube box 23 than upper tube box 22,
Tube side demarcation plate 224 is set according to number of tube passes, if number of tube passes is 2, without tube side demarcation plate 224 in lower tube box 23, on
Cover board 24 and lower cover plate 25 are symmetrically arranged rectangle cover board, and upper cover plate 24 and 25 sealing cover of lower cover plate are located at upper tube box 22 under
The top and bottom of bobbin carriage 23, upper cover plate 24 and lower cover plate 25 pass through the rectangular flange on bolt and upper tube box 22 and lower tube box 23
223 detachably connected fixations, hinged bolt when needing open upper cover plate 24 or lower cover plate 25, to bobbin carriage inside and heat exchange
It is cleaned inside pipe, as long as heat exchange unit 20 is provided with two groups or more, so that it may which realization is cleaned one by one, does not influence shell side air
Normal circulation；Cooling water from the water inlet adapter tube 241 of upper cover plate 24 enter upper tube box 22, inside fin heat exchange pipe 21, lower tube box 23,
Again upwards through inside fin heat exchange pipe 21, upper tube box 22, finally from water outlet pipe 242 draw；Every group of heat exchange unit 20 can become deformed
Same or different cooling waters, the on-off of every group of 20 cooling water of heat exchange unit can operate respectively, it can lower in cooling load
Winter-spring season dismantled cleaning one by one to bobbin carriage in the case where shell side air circulation.This non-stop-machine on-line cleaning,
Reduce production run cost；The air entered from the air intlet 1a of air heater 1 is through evaporator section 12, air bypass passage
Enter the cooling of aerial cooler 2 from first interface 1b after 14, wherein water vapour is cooled, condenses, and the condensed water of precipitation condenses upon
21 surface of fin heat exchange pipe is accumulated in bottom by gravity flow down, and shell 40, quilt is discharged by the first leakage fluid dram 26
The minor diameter liquid mist drop of air-flow entrainment enters subsequent gas-liquid separator 3.
The right side for being located at aerial cooler 2 in shell 40 is arranged in gas-liquid separator 3, and gas-liquid separator 3 is public using patent
The equipment of the number of opening 201811387224, gas-liquid separator 3 include multiple separative unit pipes 31, and separative unit pipe 31 is along shell 40
Length direction level be evenly arranged on the circular section that air flows through, since aerial cooler 2 is combined with gas-liquid separator 3 same
In shell 40, air circulation cross-section is not mutated, and needs not move through rectification, and humid air evenly distributes flow naturally and enters each point
From unit pipes 31；Separative unit pipe 31 includes water conservancy diversion and constant-current stabilizer 311, and the end of separative unit pipe is equipped with 312 He of exhaust outlet
Drain interface 313,40 bottom rear of shell are equipped with the second row of the drop discharge generated after cohesion, centrifugal sedimentation for humid air
Liquid mouth 32, humid air enters inside, and since water conservancy diversion generates rotation, wherein drop is agglomerated by multiple impact, and centrifugal sedimentation exists
