Abstract
The utility model provides a combined type residual heat recovering steam generating plant which can be simultaneously suitable for high temperature shift and low temperature difference heat transmission. The steam generating plant comprises a heat exchanger, a steam pocket and a pipeline system, wherein the heat exchanger comprises a finned tube vapour generator and a heat pipe vapour generator, the finned tube vapour generator is arranged in a chimney flue high-temperature section and connected with the steam pocket through a boiler water pipeline system, the hot side of the heat pipe vapour generator is arranged in a chimney flue low-temperature section, the cold side thereof is arranged in the steam pocket, and the cold side and the hot side are connected through a heat pipe working medium pipeline system. The steam generating plant maximizes the energy recovery in high and low grades of flue gas by utilizing the high adaptability to the flue gas temperature variation of the finned tube vapour generator and the superconductivity of low temperature difference heat transmission of a heat pipe in the heat pipe vapour generator.
Description
Technical field
The utility model relates to and is used for industrial circle high-temperature flue gas waste-heat recovery device, relates in particular to a kind of combined type waste heat recovery steam raising plant that high temperature becomes and hang down the temperature difference that adapts to.
Background technology
The high energy-consuming industry field, as chemical industry, oil, electric power, coal, industries such as building materials based on the needs of energy-saving and emission-reduction and environmental protection, have a large amount of high-temperature flue gas to discharge after waste heat recovery.Common waste-heat recovery device has following several big class at present: one, fin tube type steam generator; Two, go up lower drum formula waste heat boiler; Three, separation sleeve tubing hot-pipe steam generator.They conduct heat and layout aspect characteristics are respectively being arranged, but generally speaking, all will be according to the employed concrete environment of waste-heat recovery device, as the flue arrangement space, smoke entrance humidity etc. are selected and are determined concrete heat exchanger kind and capacity.
But above-mentioned existing waste-heat recovery device all can't be adapted to the excessive occasion of flue-gas temperature excursion.Because of it only adopts a kind of heat-exchange device of form, when flue-gas temperature exceeds or be lower than the predetermined operating mode scope of waste-heat recovery device, then possibly can't make and discharge flue gas and reach discharge standard, or cause the waste heat recovery decrease in efficiency.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of high temperature that can be applicable to simultaneously and becomes and hang down the combined type waste heat recovery steam raising plant of temperature difference heat transfer.
The utility model comprises heat exchanger, drum and pipe-line system, and described heat exchanger comprises finned tube steam generator and heat pipe steam generator; The finned tube steam generator is arranged at the flue high temperature section, and is connected with drum by furnace water pipe road system; The hot side of heat pipe steam generator is arranged at the flue low-temperature zone, and cold side is arranged in the drum, and cold side is connected by the heat-pipe working medium pipe-line system with hot side.
The adaptive capacity that the high-temperature that the utility model utilizes the finned tube steam generator to have changes, carry out the recuperation of heat of fume high-temperature relict in the flue high temperature section, the superconductivity that the low temperature difference of utilizing heat pipe steam generator to have is simultaneously conducted heat, hang down temperature difference waste heat recovery in the flue low-temperature zone, thereby make that the utility model can be so that high low-grade energy of flue gas reclaims maximization, can utilize fume afterheat fully, improve utilization rate of waste heat, and guarantee that fully the flue gas discharge temperature reaches discharge standard.
In order to make waste-heat recovery device that better applicability and operation stability be arranged, the utility model can be provided with two drums, and the finned tube steam generator is connected with first drum by furnace water pipe road system, forms first steam generating system; The cold side of heat pipe steam generator places in second drum, and is connected with the hot side of heat pipe steam generator by the heat-pipe working medium pipe-line system, forms second steam generating system.First vapour system and second vapour system are separate, and operating condition is independent, does not influence each other, and actual setting and operation that this helps carrying out according to working conditions change waste-heat recovery device are more conducive to apparatus moduleization.
The utility model utilizes the combination of finned tube steam generator and heat pipe steam generator, both can adapt to flue-gas temperature variation high temperature difference heat exchange greatly, has the superconductivity that the low temperature difference is conducted heat again; Also can realize combined modular easily simultaneously, be convenient to quick assembling.

Fig. 1 is the utility model general structure schematic diagram.
Among the figure:
The hot side 9-heat-pipe working medium of the 1-heat-pipe working medium down-comer 2-stove water down-comer 3-first drum 4-, second drum 5-heat pipe steam generator cold side 6-stove riser 7-waterborne finned tube steam generator 8-heat pipe steam generator tedge
The specific embodiment
As shown in Figure 1, the utility model comprises being respectively two relatively independent steam generating systems of heat exchanger with finned tube steam generator and heat pipe steam generator.
As shown in Figure 1, the first steam generating system structure is as follows: finned tube steam generator 7 is arranged in the gas approach high temperature section, stove water in first drum 3 is sent into fin steam generator 7 by stove water down-comer 2, steam water interface after the heat absorption is got back in first drum 2 by stove riser 6 waterborne, separates back steam through carbonated drink and outwards sends.
As shown in Figure 1, the second steam generating system structure is as follows: the hot side 8 of heat pipe steam generator is arranged in the low-temperature zone of exhanst gas outlet, and heat pipe steam generator cold side 5 places in second drum 4; The vaporization of in hot side 8, absorbing heat of working medium in the heat pipe, deliver to 5 heat releases of heat pipe steam generator cold side by heat-pipe working medium tedge 9, working medium is got back to hot side 8 by heat-pipe working medium down-comer 1 and is finished circulation after the condensation, be vaporizated into steam after the stove water heat absorption in second drum 4, after carbonated drink is separated, outwards send.
