The novel plate type air preheater has the advantages that the novel plate type air preheater is compact in structure, high in heat transfer efficiency, long in service life, convenient to machine and low in cost, and is high-temperature-resistant and high-pressure-resistant; air flue of the novel plate type air preheater flows through the elliptical straight channels and is low in flowing resistance as compared with a tubular air preheater and a finned tube air preheater; the novel plate type air preheater cannot be contaminated by dust, and the dust can be easily cleaned even of the novel plate type air preheater is contaminated by the dust.
Description
Technical field
The invention belongs to station boiler waste heat recovering energy conserving equipment technical field, it is related to a kind of plate air preheater.
Background technology
The air preheater that station boiler is adopted at present is based on tubular type, fin tube type.Its air is walked in pipe, and flue gas leads to
Cross blower fan and blow and plunder pipeline thus realizing heat exchange.Cross-flow heat exchange is adopted between flue gas and air.But this air preheater heat-energy transducer
Power is poor, needs to consume substantial amounts of tubing, and floor space is big, and because flue gas and heat exchanger tube are perpendicular contact, leads to flow resistance to increase
Plus, easy dust stratification and heat exchanger tube abrasion increase, impact air preheater life-span.
In prior art, less to the report of plate air preheater, and plate type heat exchanger has compact conformation, takes up an area face
Long-pending little, the features such as heat transfer efficiency is high, though Conventional plate-type heat exchanger compact conformation, runner is complicated, fume side and sky
Gas effluent dynamic resistance is all very big, and the easy dust stratification of fume side blocks runner, and Conventional plate-type heat exchanger needs seal with elastometic washer simultaneously,
It is inapplicable that being introduced into Conventional plate-type heat exchanger is inapplicable certainly in the air preheater of power station with high-temperature flue gas heat exchange, so
Exploitation is needed to be applied to the New-type plate air preheater of station boiler.
Content of the invention
Present invention aim at for overcoming now fin tube type, tubular air preheater exchange capability of heat at present poor, easy dust stratification, stream
Dynamic resistance these shortcomings big, thus providing a kind of station boiler plate air preheater, this air preheater have compact conformation,
Heat exchange area increases, and flue gas walks class ellipse straight channel, reduces fume side flow resistance, is difficult the tube wall that weares and teares simultaneously, is difficult to amass
Ash blocks, even if dust stratification also allows for clearing up, wavy channel between air limp, and turbulivity strengthens, and improves heat transfer efficiency, and structure
Simply, low production cost.
For achieving the above object, the utility model employs the following technical solutions:
A kind of plate air preheater, including corrugated plating heat exchange core body 1, air preheater shell 2, flue gas import and export pipe
Road and air import and export pipeline it is characterised in that described corrugated plating heat exchange core body 1 is located in air preheater shell 2, described sky
The left and right sides setting gas approach pipeline 3 of air preheater shell 2 and exhanst gas outlet pipeline 3 ', described air preheater shell 2
Upper and lower side setting air intlet pipeline 4 and air ports pipeline 4 '；Described corrugated plating heat exchange core body 1 is by some groups of plate bundles 5
Stack together by certain form, stacked using dislocation between two groups of adjacent plate bundles 5；Described corrugated plating heat exchange core body 1 is divided
It is slit into lower planes area 9, left and right plane area 10 and corrugated regions 11, the top and the bottom setting lower planes area 9 of corrugated regions 11, left and right two
Side arranges left and right plane area 10；In lower planes area 9, to folded composition plate bundle 5, its crest 12 is to crest 12 for two pieces of corrugated platings 8
Superposition, trough 13 is superimposed to trough 13, forms flue gas ellipse straight channel 6 in plate bundle at plane area 9 after welding；In left and right plane
In area 10, welding after two groups of adjacent plate bundle 5 dislocation stack forms air shell side passage 7.
In the present invention, the flue gas class ellipse straight channel 6 being formed in the middle of described plate bundle 5 is gone out with gas approach pipeline 3 and flue gas
Mouth pipeline 3 ' connection.
In the present invention, the air shell side passage 7 and air intlet pipeline 4 and the sky that are formed between described plate bundle 5 and plate bundle 5
Gas the import and export pipeline 4 ' connects.Described corrugated plating heat exchange core body is stacked together by certain form by multigroup plate bundle.Plate bundle 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, form flue gas class ellipse tubulose and lead to
Road, plate bundle and plate bundle weld formation air shell side passage after plane area stacks.
The flue gas class ellipse straight channel that described plate bundle is internally formed, this oval straight channel passage is with smoke entrance pipeline even
Logical.
Described plate bundle and the dislocation of plate interfascicular stack passage between the air plates of formation, passage and air ports pipeline between this plate
Connection, two media cross-flow heat-shift.
The invention has the beneficial effects as follows:
(1) current tubular type, the shortcoming of fin-tube type air preheater are overcome, heat exchange efficiency is greatly improved, compact conformation accounts for
Ground area is little, high temperature high voltage resistant, long service life；
(2) Novel plate type air preheater flue gas of the present invention walks oval straight channel, and flow resistance is little, and is difficult to be stained with ash and is
Make to be stained with ash and be also easy to deashing.
(3) Novel plate type air preheater of the present invention, plate bundle is welded by own layer area, need not add edge strip, welding
Amount is little, and structure is simple.
(4) Novel plate type air preheater of the present invention, cost of investment is little, low cost, simple production process, and is easy to group
Become module, easy for installation；
(5) Novel plate type air preheater of the present invention, is not only suitable for gas-gas heat exchange, is also applied for solution-air, liquid-liquid is changed
Heat, can apply to food, brewage, the field of heat exchange such as machinery, chemical industry, oil, power, metallurgy, electric power, ship.
