Description
Technical field
The present invention relates to fermentation, the air pretreatment device field of pharmaceutical industry, is specially that one kind is used for energy-saving air
The heat exchange channel structure of pretreatment unit.
Background technology
The patent of invention of Patent No. ZL200910208228.9 discloses a kind of energy-saving air preprocessing method and dress
Put, which can substitute steam to heat air, or substitute steam and be used as lithium bromide system by the Waste Heat Recovery in compressed air
The power of cold, energy-saving effect are very notable.
In the device, using rib heat exchanging pipe in the bobbin carriage of air cooling de-watering apparatus, heat exchanger tube in vertical and
It is arranged side by side, the both ends of heat exchanger tube are each passed through tube sheet and are fixed with Tube-sheet Welding.First group of pipe of air cooling de-watering apparatus
Case carries out heat exchange with high temperature air at first, the cooling water in its heat exchanger tube is heated and is changed into hot water, after long-term work, once
It is again started up, if cutting off the water supply when cutting off the water supply or clean bobbin carriage in the heat exchanger tube in first group of bobbin carriage, high temperature air（120 DEG C of ＞）By
After first group of bobbin carriage, heat exchanger tube will be made to produce expansion, the temperature of high temperature air is higher, and heat exchanger tube swell increment is bigger, due to changing
Heat pipe is fixed welding with tube sheet, therefore will drive tube sheet bulk expansion together, when being again introduced into cooling water, heat exchanger tube
Just it is easy to be retracted stress and draws bad, causes to leak.
The content of the invention
In view of the above-mentioned problems, the present invention provides a kind of heat exchange channel structure for energy-saving air pretreatment unit,
It can solve first group of bobbin carriage of existing air pretreatment device, since its heat exchanger tube is fixedly welded on tube sheet, there is heat exchange
The problem of pipe risk of leakage.
Its technical solution is such：A kind of heat exchange channel structure for energy-saving air pretreatment unit, it includes
Fin heat exchange pipe and tube sheet, the both ends of the fin heat exchange pipe are each passed through tube sheet, it is characterised in that：It further includes U-shaped elbow,
The fin heat exchange pipe is set in upper and lower multilayer, and the every fin heat exchange pipe is in being horizontally disposed with, positioned at described in same layer
In fin heat exchange pipe, the head and the tail of adjacent two fin heat exchange pipes are connected by the U-shaped elbow respectively, every layer of wing
The input end of piece heat exchanger tube is connected with water inlet pipe, and the port of export of every layer of fin heat exchange pipe is connected with outlet pipe, described
Water inlet pipe one end is closed, and the other end is connected with water inlet, outlet pipe one end closing, and the other end is connected with water outlet.
It is further characterized by：
By being welded and fixed between the fin heat exchange pipe and the U-shaped elbow.
The fin heat exchange pipe positioned at same layer is in be staggered up and down.
It further includes supporting rack, and support frame as described above is horizontally set on below the fin heat exchange pipe of bottom, the tube sheet
It is respectively perpendicular on the top surface for being fixed in support frame as described above.
Cooling medium in the fin heat exchange pipe is soft water.
The beneficial effects of the invention are as follows：
Without welding between the fin heat exchange pipe and tube sheet of the present invention, one is connected into by U-shaped elbow between fin heat exchange pipe
It is overall, when fin heat exchange pipe and high temperature air progress heat exchange, even if cutting off the water supply in pipe causes the tube swelling that exchanges heat, its expansive force
Can be digested by U-shaped elbow, tube sheet can't deform, therefore will not run into again lead to cold water when fin heat exchange pipe be retracted power draw it is bad
And the phenomenon leaked, so as to ensure that equipment installs reliability service.
