Description
Technical field
The utility model relates to a kind of boiler energy-saving system, particularly the flue gas in power station boiler residual neat recovering system.
Background technology
China's station boiler fuel is based on coal and since in the thermal coal of China sulfur content than higher, therefore, SO in the boiler smoke
2Content also higher relatively, reveal corrosion in order to guarantee the equipment acid and alkali, boiler just need be controlled at more than the acid dew-point temperature to extraneous exhaust gas temperature, normally more than 130～140 ℃, but can form to a certain degree energy dissipation like this.In addition, angle from power conversion, directly return waste heat in the boiler, its utilization ratio is the highest, therefore the backheat technology is the best mode that boiler afterheat utilizes always, but the air inlet of station boiler and flue outlet bring a lot of difficulties for heat transmission equipment and pipe design at a distance of distant.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of flue gas in power station boiler residual neat recovering system of realizing the transmission of high-effect long distance energy is provided.
The purpose of this utility model is achieved in that a kind of flue gas in power station boiler residual neat recovering system, comprise station boiler, boiler air channel and boiler flue, the boiler air channel links to each other with the station boiler air inlet, boiler flue links to each other with the flue gas in power station boiler outlet, on described boiler air channel, be furnished with the hot superconduction heat-exchange system of separate type release end of heat, on described boiler flue, be furnished with deduster successively, be connected with down-comer by tedge between separate type hot superconduction heat-exchange system heat absorbing end and the desulfurizing tower, the hot superconduction heat-exchange system of separate type heat absorbing end and the hot superconduction heat-exchange system of separate type release end of heat.
The course of work of the utility model device is:
Boiler auxiliary combustion wind enters in the station boiler combustion-supporting through the hot superconduction heat-exchange system of separate type release end of heat along the boiler air channel; Boiler smoke, is discharged after the desulfurization of process desulfurizing tower through deduster, the hot superconduction heat-exchange system of separate type heat absorbing end along boiler flue.The residual heat from boiler fume liquid refrigerant is transferred to the hot superconduction heat-exchange system of separate type release end of heat from the hot superconduction heat-exchange system of separate type heat absorbing end through tedge, heat is discharged to boiler auxiliary combustion wind, get back to the hot superconduction heat-exchange system of separate type heat absorbing end along down-comer after the liquid refrigerant heat release.
Compared with prior art, the beneficial effects of the utility model are:
1, can realize the transmission of high-effect long distance energy.
2, the direct heating boiler air blast of residual heat from boiler fume, the backheat of realization efficient energy conversion.
3, can realize waste heat recovery to flue gas in power station boiler.
4, system architecture compactness, cost is low, changes easy to maintenance.
5, system is simple, does not relate to the boiler water cycle system, safety, simple, efficient.
6, effectively avoid boiler smoke acid to reveal corrosion, the life-span is long.
7, system's operation need not power-assisted, dependable performance.
Description of drawings
Fig. 1 is the structural representation of the utility model flue gas in power station boiler residual neat recovering system.
Reference numeral among the figure:
Station boiler 1, deduster 2, boiler flue 3, boiler air channel 4, tedge 5, down-comer 6, the hot superconduction heat-exchange system of separate type heat absorbing end 7, the hot superconduction heat-exchange system of separate type release end of heat 8, desulfurizing tower 9.
The specific embodiment
Referring to Fig. 1, Fig. 1 is the structural representation of the utility model flue gas in power station boiler residual neat recovering system.As seen from Figure 1, the utility model flue gas in power station boiler residual neat recovering system, comprise station boiler 1, boiler air channel 4 and boiler flue 3, boiler air channel 4 links to each other with station boiler 1 air inlet, boiler flue 3 links to each other with station boiler 1 exhanst gas outlet, on described boiler air channel 4, be furnished with the hot superconduction heat-exchange system of separate type release end of heat 8, on described boiler flue 3, be furnished with deduster 2 successively, be connected with down-comer 6 by tedge 5 between the hot superconduction heat-exchange system of separate type heat absorbing end 7 and the desulfurizing tower 9, the hot superconduction heat-exchange system of separate type heat absorbing end 7 and the hot superconduction heat-exchange system of separate type release end of heat 8.
Described tedge, down-comer, separate type hot superconduction heat-exchange system heat absorbing end and the hot superconduction heat-exchange system of separate type release end of heat link together and constitute the closed hot superconduction heat-exchange system of separate type, not the inner vacuum state that keeps of the hot superconductive system of separate type under the duty.
Be filled with liquid refrigerant in the hot superconduction heat-exchange system of the separate type heat absorbing end 7, when being heated, the liquid refrigerant evaporation forms working substance steam, flow to the hot superconduction heat-exchange system of separate type release end of heat 8 along tedge 5, working substance steam is regelation liquefy working medium after the hot superconduction heat-exchange system of separate type release end of heat 8 is outwards emitted heat, flow back to the hot superconduction heat-exchange system of separate type heat absorbing end 7 along down-comer 6, so again and again circulation.
