The usefulness of technique scheme is:
The utility model adopts the mode that is spaced of more than one heat conduction original paper, makes the heat that heat exchanger gas phase pipe can omnibearing reception burn into dusty gas, makes the gasification of fully being heated of heat conduction complex media in the heat exchanger gas phase pipe.Fully the heat conduction complex media after the gasification contacts with the cryogenic heat exchanger liquid-phase tube that the tube wall vertical cross-section is designed to the waveform shape, and heat release liquefaction with heat transferred heat exchanger liquid phase liquid in pipe, reaches the purpose that contains corrosion component, dusty gas waste heat recovery.The utility model liquid-phase tube adopts the logical cross section of unsteady flow, and the waveform shape design of tube wall vertical cross-section has enlarged the contact-making surface of heat exchanger liquid-phase tube with gasification heat conduction complex media, makes the heat recovery rate higher.The turbulent flow that liquid forms in the heat exchanger liquid-phase tube, eddy current increase thermal conductivity factor, and it is more abundant to reclaim heat; And formed turbulent flow, eddy current can effectively wash away tube wall, have self-cleaning function, can make liquid flow smooth and easy, main is not reason make tube wall incrustation and the organic efficiency that reduces heat keeps high heat recovery efficiency.The utility model is arranged at the buffler outside with the welding position of heat exchanger liquid-phase tube and heat exchanger gas phase pipe, and the more weak link of doing corrosion is free on outside the exhaust gases passes, increases security, makes maintenance more convenient simultaneously.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the formation schematic diagram of the utility model heat exchanger liquid phase intraductal turbulance, eddy current.
The specific embodiment
The utility model now is described in conjunction with the accompanying drawings and embodiments.
As shown in Figure 1 be applicable to the waste-heat recoverer that contains corrosion component, dusty gas, be provided with an above heat conduction original paper 1 in this waste-heat recoverer housing, heat conduction original paper 1 be spaced and the heat conduction original paper between be provided with buffler 2.
As shown in Figure 1, 2, single heat conduction original paper 1 is made up of the heat exchanger liquid-phase tube 12 that a heat exchanger gas phase pipe 11 and runs through heat exchanger gas phase pipe 11.Described heat exchanger gas phase pipe 11 has certain wall thickness metal tube formation with heat exchanger liquid-phase tube 12 by holding certain pressure, the logical cross section of heat exchanger liquid-phase tube 12 pipe unsteady flows, tube wall vertical cross-section shape in wave shape.Heat exchanger liquid-phase tube 12 places buffler 2 outsides with the welding position 3 of heat exchanger gas phase pipe 11.The heat exchanger liquid-phase tube part 121 of extending heat exchanger gas phase pipe 11 is interconnected, and spaced heat conduction original paper 1 is connected as one.Be filled with heat conduction complex media 13 in the heat exchanger gas phase pipe 11 and form a pressure-bearing space 14.
The utility model waste-heat recoverer is spaced the heat conduction original paper group that forms more than one, can make and contain that corrosion component, dusty gas are omnibearing to flow around heat exchanger gas phase pipe 11, make the gasification of fully being heated of heat conduction complex media 13 in the heat exchanger gas phase pipe 11, heat conduction complex media 13 contact cryogenic heat exchanger liquid-phase tubes 12 after the gasification, heat release liquefaction, constitute the gas-liquid change procedure of a circulation, make the liquid in the heat exchanger liquid-phase tube 12 constantly absorb the heat that contains in corrosion component, the dusty gas, reach the purpose that contains corrosion component, dusty gas waste heat recovery.The utility model waste-heat recoverer conducts heat by heat conduction complex media in the heat exchanger gas phase pipe, its heat transfer will have certain start-up temperature and heat-transfer intensity to depend primarily on the wall temperature of heat exchanger gas phase pipe, thereby have heat transfer one-way, self adaptation and regulate and closing function, keep certain high wall temperature, have anticorrosive composition corrosion function.The utility model waste-heat recoverer heat exchanger liquid-phase tube and heat exchanger gas phase pipe have the metal tube formation of certain wall thickness by holding certain pressure, but the pressure that bearing capacity all gasifies and produces greater than all heat conduction complex medias in the heat exchanger gas phase pipe, thereby waste heat recovery of the present utility model dress is not afraid of dry combustion method, do not exist the heat conduction original paper booster may.As shown in Figure 2, the utility model is designed to the waveform shape with heat exchanger liquid-phase tube 12 tube wall vertical cross-sections, has enlarged the contact-making surface of heat exchanger liquid-phase tube 12 with gasification heat conduction complex media 13, and the heat recovery rate is higher.And in the heat exchanger liquid-phase tube 12, liquid has changed the Laminar Flow mode that flows and form at straight tube in flow process, and it will will form turbulent flow, eddy current in the curved portions that extends out, and increase thermal conductivity factor, and it is more abundant to reclaim heat; And formed turbulent flow, eddy current 4 can effectively wash away tube wall, have self-cleaning function, can make liquid flow smooth and easy, and main is that reason does not make tube wall incrustation and reduces the rate of recovery of heat.As shown in Figure 1, the utility model is arranged at buffler 2 outsides with the welding position of heat exchanger liquid-phase tube 12 and heat exchanger gas phase pipe 11, and the more weak link of doing corrosion is free on outside the exhaust gases passes, increases security, and maintenance is more convenient simultaneously.
Normal for guaranteeing this waste-heat recoverer operating mode operation, the utility model adopts a kind of detection method, promptly, take the waste-heat recoverer partial shell apart, as long as go to measure the temperature difference of heat exchanger liquid-phase tube 12 with a thermal detector, with the temperature difference measured and heat exchanger liquid-phase tube 12 temperature difference under the nominal situation relatively, just can draw this waste-heat recoverer or whether certain waste-heat recoverer heat exchange original paper is in normal duty, method is simple.
