Detailed description of the invention
For making those skilled in the art better understand the technical solution of the utility model, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 and Fig. 2 is the schematic diagram of the both direction of the utility model embodiment tube-sheet heat exchanger.In the present embodiment, tube-sheet heat exchanger comprises housing 1, is arranged on housing 1 both sides and the installing plate 2 be tightly connected with housing 1, two ends seal the heat exchange tube sheet 3 be arranged on installing plate 2 as can be seen from Figure.As seen from Figure 1, installing plate 2 can be provided with the air hole of multiple installation heat exchange tube sheet 3; Heat exchange tube sheet 3 to be arranged on installing plate 2 through the air hole arranged corresponding on two installing plates 2 and to be tightly connected with installing plate 2.Housing 1 also have inflow and outflow that smoke ventilator supplies high-temperature flue gas.Setting like this, the seal cavity that housing 1 and installing plate 2 are formed is isolated into by heat exchange tube sheet 3 separate air duct and exhaust gases passes, heat exchange tube sheet 3 to achieve Cryogenic air the air duct that heat formed from high-temperature flue gas in exhaust gases passes to heat exchange tube sheet 3 inner chamber conduction as intermediate thermal conductivity body, achieved the effect of high-temperature flue gas heat recovery and utilization.
In the present embodiment, heat exchange tube sheet 3 has long limit 31 and minor face 32, and wherein long limit 31 is parallel to the flue gas flow direction of tube-sheet heat exchanger, minor face 32 approximately perpendicular to the flue gas flow direction of heat exchange tube sheet 3.Minor face 32 has curved section, and that is minor face 32 is not be entirely straightway to be formed.The minor face 32 of the heat exchange tube sheet 3 of such setting has water conservancy diversion flue gas, increases the effect of flow of flue gas, makes flue gas form good advection effect, adds the actual flue gas area with heat exchange tube sheet 3 surface contact, improve heat transfer effect.
Fig. 3 and Fig. 4 is respectively the schematic diagram of two kinds of heat exchange tube sheets 3 that the utility model embodiment tube-sheet heat exchanger adopts.Heat exchange tube sheet 3 wherein in Fig. 3 forms with the arc being positioned at straightway both sides by being positioned at middle straightway, and arc is connected with the long limit 31 of heat exchange tube sheet 3; Fig. 4 directly have employed the minor face 32 of circular arc.Should expect, owing to adopting arcuate structure design, also can avoid preferably when processing heat exchange tube sheet 3 producing wedge angle in the junction of long limit 31 and minor face 32 and stress is concentrated, improve crudy and the durability of heat exchange tube sheet 3.
Can expect, in order to Leakage prevention flue gas, the installing plate 2 of heat exchange tube sheet 3 and both sides should be and is tightly connected; Optionally, the mode be tightly connected can adopt high-temperature sealing material bonding, also can adopt welded seal.Consider that heat exchange tube sheet 3 in use breakage may occur, the mode preferably adopting high-temperature material bonding, the convenient replacing to specific heat exchange tube sheet 3 and maintenance.
Same, the present embodiment is preferred, and installing plate 2 is also dismountable is fixedly mounted on housing 1.Housing 1 reality in the present embodiment for cross section be rectangle loop configuration, define heat transfer space by the cooperation of the installing plate 2 of both sides.The link of installing plate 2 and housing 1 can be arranged to the formation of ring flange and increase the sealing of seal washer form in the two contact position.
Heat exchanger heat-exchanging tube plate 3 in the present embodiment is larger relative to its cross-sectional width, therefore under the effect of long-duration static load and thermodynamic activity, zone line may occur bending and deformation, for reducing flexural deformation degree, in housing 1 in the present embodiment, be also provided with the gripper shoe 4 supporting heat exchange tube sheet 3.Because heat exchange tube sheet has achieved the isolation of exhaust gases passes and air duct, therefore the cooperation of gripper shoe 4 and heat exchange tube sheet 3 does not need sealing.In order to ensure the support force of gripper shoe, gripper shoe should be fixed on housing 1 or with housing 1 has good strength to conduct.
Also can find out from Fig. 1 and Fig. 2, the arrangement of heat exchange tube sheet in the present embodiment 3 in matrix form, installing plate 2 horizontal and vertical on all there is multiple smoke ventilator.Result in formation of the heat exchange intermediary of multiple flue gas and air, improve heat exchange efficiency by the form increasing heat exchange area, and then improve heat recovery speed.
In order to improve the flow effect of flue gas further, increase the heat exchange efficiency of unit interval, the width of the exhaust gases passes between the long limit 31 on adjacent two the heat exchange tube sheets 3 in the present embodiment is greater than the distance outside a long limit 31 of heat exchange tube sheet 3.For a heat exchange tube sheet 3, because the contact area of its long limit 31 and flue gas is comparatively large, heat exchange efficiency is higher.5:1 can be set to the length ratio of minor face 32 in long limit 31 in actual use.Certainly, this is an optimal proportion determined according to specific flue gas characteristic and air circulation characteristics; As under other conditions, other ratio also can be arranged to.In the present embodiment, the wall thickness of heat exchange tube sheet 3 can be between 0.5mm-30.0mm, can select one of them suitable numerical value according to the height of flue-gas temperature, ensure heat exchange tube sheet 3 not only can reservoir part heat, but also the better transmission of both sides heat can be realized.
In more than describing, heat exchange tube sheet 3 and installing plate 2, all should to be tightly connected between installing plate 2 and housing 1, concrete sealing adhesive or encapsulant should adopt polytetrafluoroethylene (PTFE) etc. to have good high-temperature stability and sludge proof encapsulant.
In the present embodiment, heat exchange tube sheet 3, housing 1 and installing plate 2 adopt high-quality glass steel or stainless steel.Because the sour gas such as such as sulfur dioxide can be produced after smoke combustion, in heat transfer process in flue gas steam freeze sulfur dioxide absorption gas define in strong acid be further oxidized to strong acid, possible heat exchanging tube sheet 3, housing 1 and installing plate 2 produce corrosiveness.The resistant material such as gold mining genus, high silicon boron glass, enamel, pottery, carborundum, can prevent the metal stainless steel of the actual use of the corrosion of sour gas to whole heat exchanger from can adopt 304 type stainless steel or ordinary carbon steels preferably, determine according to the high-temperature flue-gas in actual heat-exchanging state.
Tube-sheet heat exchanger in above the utility model embodiment is described in detail.Apply specific case herein to set forth principle of the present utility model and embodiment; the explanation of above embodiment just understands core concept of the present utility model for helping; when not departing from the utility model principle; also can carry out some improvement and modification to the utility model, these improve and modify and also fall in protection domain of the present utility model.
