Exchanger.
Background technology
At present used by station boiler thermal energy converter based on tubular type, fin tube type.Its air is walked in pipe, and flue gas leads to
Cross blower fan blow plunder pipeline so as to realize heat exchange.Exchanged heat between flue gas and air using cross-flow.But this thermal energy converter heat-energy transducer
For power difference, it is necessary to consume substantial amounts of tubing, floor space is big, and because flue gas and heat exchanger tube are perpendicular contacts, causes flow resistance to increase
Add, easy dust stratification and heat exchanger tube abrasion increasing, influence the life-span of thermal energy converter.
In the prior art, it is less to the report of composite plane type gas thermal energy converter, and plate type heat exchanger has structure
It is compact, the features such as floor space is small, and heat transfer efficiency is high, but Conventional plate-type heat exchanger is although compact-sized, but runner is complicated,
Fume side and air-side flow resistance are all very big, and the easy dust stratification obstruction runner of fume side, while Conventional plate-type heat exchanger needs
Seal with elastometic washer, do not apply to and exchanged heat with high-temperature flue gas, it is not certainly that Conventional plate-type heat exchanger, which is introduced into the thermal energy converter of power station,
Applicable, so needing to develop the New-type plate air preheater suitable for station boiler.
The content of the invention
Present invention aims at for overcome now current fin tube type, tubular type thermal energy converter exchange capability of heat it is poor, easy dust stratification, stream
These big shortcomings of dynamic resistance, so as to provide a kind of station boiler composite plane type gas thermal energy converter, the thermal energy exchange utensil
There is compact-sized, heat exchange area increase, flue gas walks class ellipse straight channel, reduces fume side flow resistance, while not easy to wear
Tube wall, dust stratification obstruction is not easy, even if dust stratification also allows for clearing up, wavy channel between air limp, turbulivity enhancing, improves heat transfer
Efficiency, and it is simple in construction, production cost is low.
To achieve the above object, the present invention uses following technical scheme：
A kind of composite plane type gas thermal energy converter, including corrugated plating heat exchange core body 1, thermal energy converter shell 2, flue gas

Interior, the left and right sides of the thermal energy converter shell 2 sets gas approach pipeline 3 and exhanst gas outlet pipeline 3 ', and the heat energy is handed over
The upper and lower side of parallel operation shell 2 sets air intlet pipeline 4 and air ports pipeline 4 '；If the corrugated plating heat exchange core body 1 by
Dry group plate beam 5 stacks together by certain form, is stacked between adjacent two groups of plate beams 5 using dislocation；The corrugated plating heat exchange
Core body 1 is divided into lower planes area 9, left and right plane area 10 and corrugated regions 11, and the top and the bottom of corrugated regions 11 set lower planes
Area 9, the left and right sides set left and right plane area 10；In lower planes area 9, two pieces of corrugated platings 8 form plate beam 5, its crest to folded
12 pairs of crests 12 are superimposed, and trough 13 is superimposed to trough 13, and flue gas ellipse straight channel 6 in plate beam is formed after being welded at plane area 9；
In left and right plane area 10, adjacent two groups of dislocation of plate beam 5 are welded after stacking and form air shell side passage 7.
In the present invention, the flue gas class ellipse straight channel 6 formed among the plate beam 5 goes out with gas approach pipeline 3 and flue gas
Mouth pipeline 3 ' connects.
In the present invention, the air shell side passage 7 and air intlet pipeline 4 and the sky that are formed between described plate beam 5 and plate beam 5
Gas the import and export pipeline 4 ' connects.The corrugated plating heat exchange core body is stacked together by multigroup plate beam by certain form.Plate beam be by
Two pieces of corrugated platings are connected together to stitch welding, and crest is superimposed to crest, and trough is superimposed to trough, are formed flue gas class ellipse tubulose and are led to
Road, plate beam weld after plane area stacks with plate beam and form air shell side passage.
The flue gas class ellipse straight channel that the plate beam is internally formed, the oval straight channel passage connect with smoke entrance pipeline
It is logical.
The plate beam and the dislocation of plate interfascicular stack passage between the air plates to be formed, passage and air ports pipeline between the plate
Connection, two media cross-flow heat-shift.
The beneficial effects of the invention are as follows：
(1) the shortcomings that overcoming current tubular type, fin-tube type thermal energy converter, heat exchange efficiency greatly improves, compact-sized, accounts for
Ground area is small, high temperature high voltage resistant, service life length；
(2) NEW TYPE OF COMPOSITE plane gas thermal energy converter flue gas of the present invention walks oval straight channel, and flow resistance is small, and
It is not easy to be stained with ash and is also easy to deashing even if ash is stained with.
(3) NEW TYPE OF COMPOSITE plane gas thermal energy converter of the present invention, plate beam are welded by own layer area, without addition
Edge strip, welding capacity is small, simple in construction.
(4) NEW TYPE OF COMPOSITE plane gas thermal energy converter of the present invention, cost of investment is small, and cost is low, simple production process,
And it is easy to comprising modules, it is easy for installation；
(5) NEW TYPE OF COMPOSITE plane gas thermal energy converter of the present invention, not only be applicable gas-gas heat exchange, be also applied for gas-
Liquid, liquid-liquid heat exchange, can apply to food, brewage, the heat exchange such as machinery, chemical industry, oil, power, metallurgy, electric power, ship is led
