Description
Technical field
The utility model is related to the technical field of heat exchangers in mechanical equipment, especially a kind of flue gas high-performance heat exchanger.
Background technology
In station boiler, kiln gas exhaust apparatus, to reduce exhaust gas temperature, desulphurization and denitration, purifying and dedusting work are improved
Skill efficiency, much using the heat exchanger of traditional straight type light-pipe structure, and the light pipe arrangement big heat exchange efficiency in gap is low, flue gas into
Part is complicated, and flow field arrangement limitation causes its dust stratification serious, and it is very big inconvenient to come for maintenance of equipment cleaning tape, simultaneously because exchanger body
Product is huge, and physical device cost and operating cost are very big.
The content of the invention
The purpose of this utility model is aiming at the above problem existing for traditional straight trip light-pipe structure heat exchanger and deficiency
Part provides a kind of energy-saving and environment-friendly flue gas high-performance heat exchanger.
The concrete scheme of the utility model is：A kind of flue gas high-performance heat exchanger has chan frame, phase on chan frame
To being disposed with left tube sheet and right tube plate, side block aerofoil is additionally provided in the front and rear sides of chan frame, between left tube sheet and right tube plate
Equipped with several heat exchanger tubes, the both ends of heat exchanger tube it is protruding on right tube plate from left tube sheet respectively and with the Tubesheet Welding of corresponding one side
It is connected together, the heat exchanger tube is distortion type pipe, and all heat exchanger tubes are bundled into an entirety using steel band.
According to the difference of the heat exchange tube diameter of different size and its degreeof tortuosity, the row of all heat exchanger tubes in the utility model
Any one mode that cloth section may be employed in the wrong row three of square, equilateral triangle and Unequal distance is arranged.
After cold and hot fluid enters heat exchanger by pipeline in the utility model, fluid is along the direction of heat exchange tube wall distortion
Flowing, changes the outer flow direction for sweeping away heat exchanger tube of direct current in traditional pipe, pipe, and heat exchanger tube is turned round according to the caliber of different size
Qu Chengdu is different, and arrangement form has wrong row of square, equilateral triangle, Unequal distance etc., greatly improves its heat exchange efficiency.
Heat exchanger tube dust stratification problem greatly reduces cleaning conveniently in the utility model heat exchanger, and heat exchange efficiency improves, Er Qiehuan
Hot device is compact-sized, and operating cost is low.
Description of the drawings
Fig. 1 is the structure diagram of the utility model（Containing partial sectional view）；
Fig. 2 is the utility model side-looking direction structure diagram.
In figure：1-chan frame, 2-left tube sheet, 3-side block aerofoil, 4-heat exchanger tube, 5-steel band, 6-right tube plate.
Specific embodiment
The utility model is a kind of flue gas high-performance heat exchanger, positioned opposite on chan frame to have a left side with chan frame 1
Tube sheet 2 and right tube plate 6 are additionally provided with side block aerofoil 3 in the front and rear sides of chan frame, are equipped between left tube sheet and right tube plate several
Heat exchanger tube 4, the both ends of heat exchanger tube are protruding on right tube plate from left tube sheet respectively and Tube-sheet Welding with corresponding one side is one
It rises, the heat exchanger tube is distortion type pipe, and all heat exchanger tubes are bundled into an entirety using steel band 5.
According to the difference of the heat exchange tube diameter of different size and its degreeof tortuosity, the arrangement of all heat exchanger tubes in the present embodiment
Any one mode that section may be employed in the wrong row three of square, equilateral triangle and Unequal distance is arranged.
Heat exchanger tube in the present embodiment, which is tied up, may be employed first regional area steel band and ties up, then the whole shape tied up with steel band
Formula carries out.
After cold and hot fluid enters heat exchanger by pipeline in the utility model, fluid is along the direction of heat exchange tube wall distortion
Flowing, changes the outer flow direction for sweeping away heat exchanger tube of direct current in traditional pipe, pipe, and heat exchanger tube is turned round according to the caliber of different size
Qu Chengdu is different, and arrangement form has wrong row of square, equilateral triangle, Unequal distance etc., greatly improves its heat exchange efficiency.
Heat exchanger tube dust stratification problem greatly reduces cleaning conveniently in the utility model heat exchanger, and heat exchange efficiency improves, Er Qiehuan
Hot device is compact-sized, and operating cost is low.
