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, relate to a kind of New-type plate air preheater.
Background technology
The air preheater that station boiler adopts at present be take tubular type, fin tube type as main.Its air is walked in pipe, thereby flue gas is blown and plunderred pipeline and realize heat exchange by blower fan.Between flue gas and air, adopt cross-flow heat exchange.But this air preheater exchange capability of heat is poor, need to consume a large amount of tubing, and floor space is large, and because flue gas and heat exchanger tube are vertical contacts, cause flow resistance to increase, easily dust stratification and heat exchanger tube wearing and tearing strengthen, and affect the life-span of air preheater.
In prior art, report to plate air preheater is less, and plate type heat exchanger has compact conformation, floor space is little, heat transfer efficiency high, although but traditional plate type heat exchanger compact conformation, but runner is complicated, fume side and air side flow resistance are all very large, and the easy dust stratification of fume side blocks runner, traditional plate type heat exchanger needs seal with elastometic washer simultaneously, inapplicable and high-temperature flue gas heat exchange, it is inapplicable certainly that traditional plate type heat exchanger is introduced in the air preheater of power station, so need exploitation to be applicable to the New-type plate air preheater of station boiler.
Summary of the invention
The object of the invention is as overcoming now at present fin tube type, tubular air preheater exchange capability of heat is poor, easy dust stratification, large these shortcomings of flow resistance, thereby provide a kind of station boiler New-type plate air preheater, this air preheater has compact conformation, heat exchange area increases, flue gas is walked the oval straight channel of class, reduced fume side flow resistance, be difficult for wearing and tearing tube wall simultaneously, be difficult for dust stratification and block, even if dust stratification is also convenient to cleaning, wavy channel between air limp, turbulivity strengthens, and has improved heat transfer efficiency, and simple in structure, production cost is low.
For achieving the above object, the utility model is by the following technical solutions:
A kind of New-type plate air preheater, comprise corrugated plating heat exchange core body 1, air preheater shell 2, flue gas import and export pipeline and air import and export pipeline, it is characterized in that described corrugated plating heat exchange core body 1 is positioned at air preheater shell 2, the left and right sides of described air preheater shell 2 arranges gas approach pipeline 3 and exhanst gas outlet pipeline 3 ', and the upper and lower side of described air preheater shell 2 arranges air intlet pipeline 4 and air ports pipeline 4 '; Described corrugated plating heat exchange core body 1 is stacked together by certain form by some groups of plate bundles 5, adopts dislocation to stack between two groups of adjacent plate bundles 5; Described corrugated plating heat exchange core body 1 is divided into upper and lower plane area 9,10He corrugated regions, left and right plane district 11, and the top and the bottom of corrugated regions 11 arrange upper and lower plane area 9, and the left and right sides arranges left and right plane district 10; In upper and lower plane area 9,8 pairs of folded formation plate bundles 5 of two corrugated platings, 12 stacks of 12 pairs of crests of its crest, 13 stacks of 13 pairs of troughs of trough, the oval straight channel 6 of flue gas in formation plate bundle after plane area 9 places welding; In left and right plane district 10, adjacent two groups of plate bundles, 5 dislocation stack rear welding and form air shell side passage 7.
In the present invention, the oval straight channel 6 of flue gas class forming in the middle of described plate bundle 5 is communicated with gas approach pipeline 3 and exhanst gas outlet pipeline 3 '.
In the present invention, the air shell side passage 7 forming between described plate bundle 5 and plate bundle 5 is communicated with air intlet pipeline 4 and air ports pipeline 4 '.Described corrugated plating heat exchange core body stacks together by certain form by organizing plate bundle more.Plate bundle is by two corrugated platings, stitch welding to be connected together, and crest superposes to crest, and trough superposes to trough, forms the oval tubular conduit of flue gas class, and plate bundle and plate bundle weld and form air shell side passage after plane area stacks.
The oval straight channel of the inner flue gas class forming of described plate bundle, this ellipse straight channel passage and smoke entrance pipeline connection.
The dislocation of described plate bundle and plate interfascicular stacks passage between the air plates of formation, passage and air ports pipeline connection between this plate, two media cross-flow heat-shift.
The invention has the beneficial effects as follows:
(1) overcome the shortcoming of current tubular type, fin-tube type air preheater, heat exchange efficiency significantly improves, compact conformation, and floor space is little, high temperature high voltage resistant, long service life;
(2) New-type plate air preheater flue gas of the present invention is walked oval straight channel, and flow resistance is little, even and if be difficult for being stained with ash and be stained with ash and be also easy to deashing.
(3) New-type plate air preheater of the present invention, plate bundle welds by self plane area, and without adding edge strip, welding capacity is little, simple in structure.
(4) New-type plate air preheater of the present invention, cost of investment is little, and cost is low, and production technology is simple, and is easy to form module, easy for installation;
(5) New-type plate air preheater of the present invention, not only applicable gas-gas heat exchange, is also applicable to solution-air, the heat exchange of liquid-liquid, can be applied to food, brewages, the heat exchange field such as machinery, chemical industry, oil, power, metallurgy, electric power, boats and ships.
