Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described.
Inner-tube structure of the present invention as shown in Figure 2, comprises cylindrical shell 1, salient mounting end socket 2, recessed dress end socket 3, some flue gas arms 4, some flue gas disturbed flow pipes 5, flue gas house steward 8 and some anode stubs 6; Wherein, salient mounting end socket 2 is contained in the top of cylindrical shell 1, recessed dress end socket 3 is arranged on the bottom of cylindrical shell 2, flue gas arm about 4 is inner through cylindrical shell 1, the top of flue gas arm 4 is communicated with (as shown in Figure 4) with the bottom of flue gas house steward 8, the bottom of flue gas arm 4 is communicated with the lower space of recessed dress end socket 3, and the top of flue gas house steward 8 is through salient mounting end socket 2.Form a water storage cavity closed between cylindrical shell 2, flue gas arm 4, flue gas house steward 8, salient mounting end socket 2 and recessed dress end socket 3, flue gas disturbed flow pipe 5 is placed in flue gas arm 4, and the top and bottom of flue gas disturbed flow pipe 5 is communicated with water storage cavity respectively.The body of anode stub 6 is placed in this water storage cavity through the salient mounting end socket 2 at top; as sacrificial anode to protect water storage to the corrosion of inner bag inwall; and flue gas house steward 8 is provided with some anode stubs crosses cover 61; the two ends up and down that cover 61 runs through flue gas house steward 8 crossed by this anode stub; anode stub 6 crosses cover 61 through anode stub; and be not in contact with it, to ensure that the sacrificial anode function of anode stub 6 can not lose efficacy.
The maximum improvement of the present invention is, at the lower surface of recessed dress end socket 3, some first weldering nails 31 are installed, the inwall of smoke pipe 4 secures some second weldering nails 41, and the design of flue gas disturbed flow pipe 5, the outer wall of this flue gas disturbed flow pipe 5 is provided with some 3rd weldering nails 51, this flue gas disturbed flow pipe can play the function identical with flue gas spoiler, namely the chance that flue gas contacts with smoke pipe is increased, improve the holdup time of flue gas in smoke pipe, in addition flue gas disturbed flow pipe 5 inner hollow, and be all communicated with water storage cavity up and down, after water heating, a hot water cyclesystem can be formed, increase the thermal convection current intensity of water storage in inner bag, 3rd weldering nail 51 also serves the effect increasing flue gas disturbed flow pipe 5 heat exchange area, in addition, the design of this programme Multi exhaust, considerably increase inner bag overall heat exchange area, take full advantage of the heat energy in flue gas, thus increase effectively the overall heat exchange ability of inner bag, improve the utilization ratio of heat energy.
In order to increase heat exchange area further, the first weldering nail 31, second welds nail 41 and the 3rd weldering nail 51 all adopts nail to establish threaded welding screw with it, thus effectively increase the heat exchange area of weldering nail, as shown in Figure 3.
In order to promote the heat transfer effect of inner bag further, the lower surface of recessed dress end socket 3 is designed to concavity curved surface by inventor, thus increases the heat exchange area of its lower surface further, promotes the heat transfer effect of inner bag.
The distributed architecture schematic diagram of what accompanying drawing 4 showed is flue gas arm 4, flue gas house steward 8 and anode stub 6.
By reference to the accompanying drawings 2, operation principle of the present invention is as follows:
Recessed dress end socket 3 lower space places a burner 7, combustion gas is burnt by burner 7 and is produced high-temperature flue gas, high-temperature flue gas and recessed dress end socket 3 lower surface and lower surface weld first welds nail 31 and contacts, pass through heat exchange, heat is passed in the water in water storage cavity, simultaneously, flue gas continues to rise by smoke pipe 4, in the process that flue gas rises, heat exchange is carried out further with smoke pipe 4 and flue gas disturbed flow pipe 5 and flue gas house steward 8, again heat is passed in the water in water storage cavity, and the second weldering nail 41 increases the heat exchange area of smoke pipe, 3rd weldering nail 51 increases the heat exchange area of flue gas disturbed flow pipe 5, cold water bottom flue gas disturbed flow pipe rises after heating, then by top connected entrance, be circulated to the top of water storage cavity, increase the thermal convection current intensity in water storage liner, thus greatly improve overall heat exchange efficiency, flue gas is collected in flue gas house steward 8 finally by each flue gas arm 4 and discharges.This programme is compared with the traditional inner-tube structure mentioned in background technology, and heat the identical water yield to identical temperature, the fuel that this programme consumes is less, and therefore, this programme is also more energy-conservation than traditional scheme.
