The economizer that present station boiler adopts is based on tubular type, fin tube type.Its condensate water is walked in the pipe, plunders pipeline realization heat exchange thereby flue gas blows by blower fan, adopts the cross-flow heat exchange between flue gas and the condensate water.But this economizer compactness is low, needs to consume a large amount of tubing, and floor space is big, and because flue gas is vertical the contact with heat exchanger tube, causes flow resistance to increase, and the wearing and tearing of dust stratification and heat exchanger tube strengthen easily, influence the life-span of economizer.
In the prior art, patent publication No. provides a kind of station boiler board-like economizer for the utility model patent of CN202253576U.This patent has influenced the smoke entrance flow and has strengthened flue gas resistance because smoke entrance plate plane area spacing has only half of ripple height.Simultaneously, the corrugated cardboard sheet of this board-like economizer is that the light face is straight-through, though can reduce flue gas resistance, fume side does not have the heat transfer measure of reinforcement, must cause the fume side coefficient of heat transfer low, can cause the result of whole economizer heat-transfer effect difference unavoidably.In addition, because flue gas and water ratio, density and coefficient of heat transfer gap are bigger, and the water side heats up not obvious, if do not consider the series connection of water side, then can only remedy inevitable like this volume and the cost that can increase economizer by increasing heat exchange area.
The utility model content
The purpose of this utility model is that flue gas and water density, the coefficient of heat transfer differ too big in the prior art in order to overcome, the water side not obvious problem that needs to increase aquaporin length that heats up, thus a kind of station boiler shell-and-plate economizer is provided.
Shell-and-plate economizer compact conformation, heat exchange area that the utility model provides are big, and have increased the turbulivity of flue gas fluid, therefore, good effect of heat exchange, have from the deashing function and are not easy dust stratification and fouling, and production cost is low.
For achieving the above object, the utility model is by the following technical solutions:
A kind of shell-and-plate economizer, comprise the corrugated plating heat exchange core body, outer cover of heat exchanger, first, second water entrance water tank, first, second smoke entrance pipeline, wherein, described corrugated plating heat exchange core body is located in the outer cover of heat exchanger, the upper and lower side of corrugated plating heat exchange core body front side is respectively equipped with first, second water entrance water tank, and the upper and lower both sides of corrugated plating heat exchange core body are provided with first, second smoke entrance pipeline.
Described corrugated plating heat exchange core body comprises that end plate and some groups vertically insert the plate bundle of end plate with a determining deviation, and the spacing of adjacent panel bundle (5) is 0～100mm.
Described plate bundle is that the corrugated plating of the upset that is adjacent by a corrugated plating is formed by stacking, the contact that leans of the crest of adjacent two corrugated platings, and two corrugated cardboard sheets are against the position sealing of contact, and the space between the adjacent seals line is formed with the tubulose circulation canal.Described sealing means is preferably laser welded seal, and potted line is sealing wire.
Adjacent two potted lines are distributed on the plate bundle equidistantly; A wherein end of potted line links to each other with front side or the rear side of plate bundle, and the other end is 0～100mm apart from the distance of plate Shu Houduan or front end.Why potted line is not connected with the front end of plate bundle or rear end simultaneously is tubulose circulation canal in the middle of forming.
Described tubulose circulation canal is communicated with first, second water entrance water tank, and the flow media in the tubulose circulation canal is water.
Adjacent plate bundle intersection dislocation horizontal positioned, the space that adjacent plate interfascicular forms is shell side.
Flow media in the described tubulose circulation canal is water, and the flow media in the shell side is flue gas, and two media becomes the form heat-shift of cross-flow, adverse current and cross-flow.
The utility model has the advantages that:
(1) medium all heat exchange surfaces in heat exchange core body all are one-time surfaces, and heat exchange efficiency significantly improves, compact conformation, and floor space is little;
(2) the utility model shell-and-plate economizer had both kept the plate type heat exchanger compact conformation, characteristics of high efficiency, the characteristics that have the shell-and-tube heat exchanger high temperature high voltage resistant again make it have the heat transfer efficiency height, and the pressure loss is little, be difficult for dust stratification and block, even dust stratification also is convenient to cleaning;
(3) solved because flue gas and water density differ too big, the water side heats up, and not obvious needs repeatedly circulate or the problem of needs increase aquaporin length,
(4) plate interfascicular staggered superposition forms the shell side passage, and flue gas is walked the shell side wavy channel, has increased the turbulivity of flue gas fluid, has improved heat transfer efficiency;
(5) the utility model shell-and-plate economizer, cost of investment is little, and cost is low, and production technology is simple, and is easy to form module, and is easy for installation.
