Description
Technical field
The utility model relates to a kind of energy-saving appliance, particularly a kind of boiler hot exchange system energy-saving appliance.
Background technology
Heat-exchange system water side adopts continuous circulation heat exchange, normal pressure operational mode, test pressure: 1.2Mpa, operating pressure: < 0.2MPa.System is provided with and is independently incubated regulating tank, and the no matter boiler whether moisturizing that is in operation has soft water all the time at flow recovery waste heat can store heat of atmospheric circulating in chimney heat exchanger, and current energy-saving appliance inside adopts heat-exchange tube more, and its heat exchanger effectiveness is low.
Summary of the invention
In order to solve the problem of prior art, the utility model provides a kind of boiler hot exchange system energy-saving appliance, the heat in recovery boiler flue gas, the thermal efficiency of raising boiler.
Described technical scheme is as follows:
A kind of boiler hot exchange system energy-saving appliance, comprise housing, the upper and lower both sides of described housing arrange respectively cylinder and lower cylinder, on described upper cylinder, be provided with exhanst gas outlet, on described lower cylinder, be provided with gas approach, described housing upper right side is provided with cooling water inlet, described housing lower right side is provided with coolant outlet, enclosure interior is provided with plate pipe group, in plate pipe group, flow respectively cooling water and flue gas, and described plate pipe group is stamped to form by plate.
Plate strikes out emboss pit as runner, and two runners form a plate bundle, and two or more plate bundles form plate pipe group.
This heat exchanger is welded into plate pipe by plate with argon arc welding machine, and plate pipe is comprised of housing, upper cylinder and lower cylinder three parts again.
Plate is stainless sheet steel, and thickness is 0.7mm.Because of condensed water nitrogenate acidity, so selected 316L material.Corrosion resistant plate is struck out to convex-concave cross section as runner, the part in the middle of it, the top of tongue is relative to the top of tongue the strong point, maintains the spacing between plate, forms the intermediate distance of runner.Two runners form a plate bundle, and two or more plate bundles form plate pipe group.A runner stream flue gas, another runner stream chilled water.The upper lateral part of plate pipe group is provided with chilled water inlet, and side lower part is provided with chilled water outlet.Chilled water and flue gas are the heat exchange of cross flow in plate both sides, by heat transfer process, first the flue gas of 170 ℃ is reduced to 58 ℃ of dew points and discharges after sensible heat, then the flue gas cool-down to 30 of 58 ℃ ℃ is discharged to Latent heat and crosses cold sensible heat.
Plate strikes out convex-concave cross section as runner, has improved the rigidity of thin plate, can guarantee again the cross section requirement of flue gas flow channel and chilled water runner.
The beneficial effect that the technical scheme that the utility model embodiment provides is brought is:
(1) heat transfer efficiency is high: have heat transfer efficiency high, the advantage such as heat exchange amount is large, and fluid pressure drop is little, and radiation loss is little;
(2) applied widely: because plate tube bank and pressure strip all adopt stainless steel Welding Structure, according to welding performance, flue gas heat-exchange unit can move under the operating mode of temperature≤500 ℃.
(3) compact conformation: floor space is little, easy for installation, reliable.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural front view of a kind of boiler hot exchange system energy-saving appliance of the present utility model;
Fig. 2 is the structure left view of a kind of boiler hot exchange system energy-saving appliance of the present utility model;
Fig. 3 is the structure top view of a kind of boiler hot exchange system energy-saving appliance of the present utility model.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
Embodiment mono-
A kind of boiler hot exchange system energy-saving appliance, comprise housing 1, described housing arranges respectively cylinder 2 and lower cylinder 3 in both sides Shang Xia 1, on described upper cylinder 2, be provided with exhanst gas outlet 4, on described lower cylinder 3, be provided with gas approach 5, described housing 1 upper right side is provided with cooling water inlet 6, described housing 1 lower right side is provided with coolant outlet 7, housing 1 inside is provided with plate pipe group 8, interior cooling water and the flue gas of flowing respectively of plate pipe group 8, and described plate pipe group 8 is stamped to form by plate.
Plate strikes out emboss pit 9 as runner, and two runners form a plate bundle, and two or more plate bundles form plate pipe group.
Flue gas flows into plate tube bank runner 10 from bottom to top, and chilled water is restrained runner 10 from upper cross to flowing into plate, and flows out from side lower plate tube bank runner, forms " distributary and adverse current " heat exchange.With two stainless steel corrugated cardboard sheets, form a plate pipe group, effect that corrugated design has quiet " stirring " can form turbulent flow under lower Reynolds number, and to improve heat exchange efficiency, its principle is as follows:
The first step, first reduces exhaust gas temperature to close dew temperature, to utilize the sensible heat of flue gas;
Second step, by the steam of dewfall again heat release to dew point water, to utilize H in flue gas
2the latent heat of O steam-condensation (utilizing higher calorific value).
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
Claims (2)
