Description

A kind of board-like gas gas-heat exchanger
Technical field
The present invention relates to waste heat recovering energy conserving equipment technical field, especially a kind of New-type plate gas gas-heat exchanger, can It is applied to station boiler, industrial heating furnace, pyrolysis furnace etc..
Background technology
Heat exchanger heat transfer type is broadly divided into three kinds:Heat transfer, convection current and radiation.Gas gas-heat exchanger is belonging to convection current Heat-conducting mode, heat is partially transferred to the relatively low part of temperature or is delivered to what is contacted from thing body temperature is higher The process of the relatively low another object of temperature is referred to as heat transfer, abbreviation heat conduction.Gas gas-heat exchanger is exactly temperature gas transmission high Equipment of the heat to the low space of temperature.
The gas gas-heat exchanger that current station boiler is used is based on tubular type, fin tube type.Its air is walked in pipe, flue gas Blown by blower fan and plunder pipeline so as to realize heat exchange.Exchanged heat using cross-flow between flue gas and air.But this gas gas-heat exchanger is changed Hot ability is, it is necessary to consume substantial amounts of tubing, floor space is big, and because flue gas and heat exchanger tube are perpendicular contacts, cause stream Resistance increase, easy dust stratification and heat exchanger tube abrasion are increased, and influence the life-span of air preheater.
Conventional corrugation plate formula heat exchanger (heat-exchangers of the plate type) is by stamping Concavo-convex stainless steel plate composition.Concave convex texture between two adjacent plates is into 180 degree relative combinations, therefore the plate of heat-exchangers of the plate type two Concavo-convex crestal line between piece forms contact point staggeredly, after contact point is combined in vacuum welding mode, is formed board-like The high pressure resistant staggeredly currency structure, these currency structures for interlocking of heat exchanger are so that the cold fluid and hot fluid in heat-exchangers of the plate type is produced Give birth to strong turbulent flow and reach heat transfer effect high.Heat-exchangers of the plate type is made up of one group of wavy metal plate, there is four corner apertures on plate, Two kinds of liquid for conducting heat pass through.Metal sheet has in the framework of fixed plate and movable pressure plate installed in a side, is used in combination Fishbolt is clamped.Gasket seal is housed on plate, fluid passage is sealed, and guide fluid alternately to flow to respective stream In road, heat exchange is formed.The flow of fluid, physical property, pressure drop and temperature difference determine the quantity and size of plate.Ripple Plate not only increases turbulent extent, and forms many supporting-points, it is sufficient to bear the pressure differential between medium.Metallic plate and portable plate Pressure strip is suspended on top guide bar, and is positioned by lower guide rod, and rod end is then fixed on the support columns.
In the prior art, the report to board-like gas gas-heat exchanger is less, and heat-exchangers of the plate type has compact conformation, accounts for Ground area is small, and the features such as heat transfer efficiency is high, although Conventional plate-type heat exchanger compact conformation, runner is complicated, fume side with Air-side flow resistance is all very big, and the easy dust stratification obstruction runner of fume side, while Conventional cryogenic heat-exchangers of the plate type needs rubber Rubber sealing or spring are compressed, or use welding structure, are not applied to and are exchanged heat with high-temperature flue gas, by Conventional plate-type heat exchanger Be introduced into power station as in air preheater using being certainly inapplicable, so needing to develop a kind of New-type plate gas gas heat exchange Device, can be applied to the fields such as station boiler, industrial heating furnace, pyrolysis furnace.
The content of the invention
Present invention aim to overcome the board-like gas gas of now current fin tube type, tubular air preheater or other forms The exchange capability of heat of heat exchanger is poor, easy dust stratification, big these shortcomings of flow resistance, so that a kind of board-like gas gas-heat exchanger is provided, There is the board-like gas gas-heat exchanger compact conformation, heat exchange area to increase, and flue gas walks class ellipse straight channel, reduces flue gas effluent Dynamic resistance, while being difficult the tube wall that weares and teares, is difficult dust stratification obstruction, even if dust stratification also allows for cleaning, wavy channel between air limp is rapid Mobility strengthens, and improves heat transfer efficiency, and simple structure, low production cost.
To achieve the above object, the present invention uses following technical scheme:
A kind of board-like gas gas-heat exchanger, including corrugated plating heat exchange core body, board-like gas gas-heat exchanger shell, first gas medium The import and export pipeline, second gas medium inlet and outlet pipeline;Described corrugated plating heat exchange core body is outside board-like gas gas-heat exchanger In shell, the upper and lower side of corrugated plating heat exchange core body is provided with first gas medium inlet and outlet pipeline, the left and right two of corrugated plating heat exchange core body Side is provided with second gas medium inlet and outlet pipeline;
The corrugated plating is stamped and formed out plane area, plate inner plane area and corrugated regions and constitutes by flat board;
The corrugated plating heat exchange core body is welded on one with corrugated plating according to two adjacent panels beams by multigroup plate beam after plane area is stacked The form for rising, crest is superimposed to crest, and trough is superimposed to trough, and plate beam is internally formed first gas medium class ellipse tubulose and leads to Road, welding forms second gas medium shell side passage after plane area is stacked between two adjacent panels beams.
Further, the first gas medium class ellipse straight channel that the plate beam is internally formed, be and first gas medium Import and export pipeline connection.
Further, between the two adjacent panels beam after plane area is stacked welding formed second gas medium shell side lead to Road, be and second gas medium import and export pipeline connection.
Further, first gas medium and second gas medium cross-flow heat-shift.
Further, the first gas medium is flue gas, and second gas medium is air.
Further, plate inner plane area is provided with inside corrugated plating, two adjacent panels beams are folded by plate inner plane area Put, play a part of reinforcement, support whole air preheater structure.
Further, interconnected by welding metal expansion joint between two adjacent corrugated plate heat exchange core bodies.The metal is swollen Swollen section can the lower thermal expansion for absorbing corrugated plating heat exchange core body in working order.
The method have the advantages that:
(1)Current tubular type, the shortcoming of fin-tube type air heat exchanger are overcome, heat exchange efficiency is greatly improved, compact conformation, taken up an area Area is small, high temperature high voltage resistant, long service life;
(2)The board-like gas gas-heat exchanger flue gas of the present invention walks oval straight channel, and flow resistance is small, even and if being difficult to be stained with ash and being stained with ash Also it is easy to deashing.
(3)The board-like gas gas-heat exchanger of the present invention, plate beam is welded by own layer area, without adding edge strip, welding capacity It is small, simple structure.
(4)The board-like gas gas-heat exchanger of the present invention, cost of investment is small, low cost, simple production process, and is easy to composition Module, it is easy for installation;
(5)The board-like gas gas-heat exchanger of the present invention, is not only applicable gas-gas heat exchange, is also applied for solution-air, liquid-liquid heat exchange, can be with Be applied to food, brewage, the field of heat exchange such as machinery, chemical industry, oil, power, metallurgy, electric power, ship.
