Description

The long flue atmospheric energy-saving of superconductor heat exchange boiler

Technical field

The utility model relates to a kind of boiler, the long flue atmospheric energy-saving of particularly a kind of superconductor heat exchange boiler.

Background technology

Existing boiler, the flue-gas temperature at its outlet flue place is higher, and the heat energy utilization rate of boiler is reduced greatly; In order to improve the heat energy utilization rate, utilize the air intake of the smoke pre-heating boiler of heat, so, the heat energy utilization rate still is undesirable.

The utility model content

The utility model is to have the low problem of boiler hot utilization rate now in order to solve, and provides a kind of heat utilization efficiency the high long flue atmospheric energy-saving of superconductor heat exchange boiler.

The utility model includes body of heater, burner hearth and traveling-grate stoker, and burner hearth is positioned at the bottom of body of heater, and traveling-grate stoker is arranged in burner hearth; The utility model also includes first heat exchanger and second heat exchanger; First heat exchanger and second heat exchanger constitute body of heater, and first heat exchanger is positioned at upper furnace, and second heat exchanger is positioned at the first heat exchanger top; First heat exchanger is made up of superconductor and at least one group of smoke pipe; Every group of smoke pipe has a smoke pipe at least, and smoke pipe is immersed in the superconductor, and smoke pipe is communicated with burner hearth; Second heat exchanger is made up of the circulating water pipe and the gaseous state superconductor of coiling, and the circulating water outlet of circulating water pipe is positioned at the second heat exchanger top, and the circulating water intake of circulating water pipe is positioned at the second heat exchanger bottom.

The course of work and the principle of the utility model are:

Fuel burns in burner hearth; The heat that produces directly heats the superconductor in first heat exchanger of top; The flue gas that burning produces is discharged through smoke pipe, owing to smoke pipe is immersed in the superconductor, so; Heat in the flue gas passes to superconductor through the thickness pipe, and the heat energy that fuel combustion is produced is fully utilized.

After superconductor is heated, gasification rapidly, the steam of superconductor enters into second heat exchanger rapidly and carries out heat exchange with the circulating water pipe that coils, and with heat transferred recirculated water, the superconductor that condenses is directly got back in first heat exchanger.

The beneficial effect of the utility model is: the thickness pipe is immersed in the superconductor, and superconductor absorbs the heat of flue gas fully, and the heat energy utilization rate of fuel is high; After superconductor is heated, gasifies rapidly and enter into second heat exchanger and carry out heat exchange, heat transferred recirculated water with the circulating water pipe that coils.

The specific embodiment

See also Fig. 1, Fig. 2 and shown in Figure 3, the utility model is made up of body of heater 1, burner hearth 2 and traveling-grate stoker 3, and burner hearth 2 is positioned at the bottom of body of heater 1; Traveling-grate stoker 3 is arranged in burner hearth 2, the first heat exchangers 4 and second heat exchanger 5 constitutes body of heater 1, the first heat exchanger 4 and second heat exchanger 5 is positioned among the body of heater 1; First heat exchanger 4 is positioned at burner hearth 2 tops; Second heat exchanger 5 is positioned at first heat exchanger, 4 tops, and first heat exchanger 4 is made up of superconductor 41 and at least one group of smoke pipe, and every group of smoke pipe has a smoke pipe 42 at least; Smoke pipe 42 is immersed in the superconductor 41, and smoke pipe 42 is communicated with burner hearth 2; Second heat exchanger 5 is made up of with gaseous state superconductor 51 circulating water pipe 52 of a coiling, and the circulating water outlet 54 of circulating water pipe 52 is positioned at second heat exchanger, 5 tops, and the circulating water intake 53 of circulating water pipe 52 is positioned at second heat exchanger, 5 bottoms.

The quantity of the circulating water pipe 52 of the coiling in said second heat exchanger 5 is decided according to actual conditions.

As depicted in figs. 1 and 2; In the present embodiment, A, B, C, D, E, F and seven groups of smoke pipes of G of arranging about first heat exchanger 4 has, D group smoke pipe has 12 smoke pipes 42; All the other group smoke pipes respectively have six roots of sensation smoke pipe 42; The rear end of A group smoke pipe and G group smoke pipe is communicated with burner hearth 2, and the front end of A group smoke pipe and B group smoke pipe is communicated with through the first outside ash door 43, and the rear end of B group smoke pipe and C group smoke pipe is communicated with through the second outside ash door 44; The front end of G group smoke pipe and F group smoke pipe is communicated with through the 5th outside ash door 47; The rear end of F group smoke pipe and E group smoke pipe is communicated with through the 4th outside ash door 46, and the front end of E group smoke pipe and C group smoke pipe all is communicated with the front end of D group smoke pipe through the 3rd outside ash door 45, and the rear end of D group smoke pipe is communicated with chimney.In addition, the quantity of the smoke pipe group in first heat exchanger 4 is not limit, and the smoke pipe quantity in every group of smoke pipe is not limit, and decides according to the tonnage and the actual needs of boiler;

The course of work and the principle of present embodiment are:

Fuel burns in burner hearth, and the heat of generation directly to the superconductor heating in first heat exchanger 4 of top, discharge through smoke pipe 42 by the flue gas that burning produces; Because smoke pipe 42 is immersed in the superconductor 41; And organize smoke pipe more and be interconnected, the smoke pipe that extended, so; Heat in the flue gas passes to superconductor 41 through thickness pipe 42, and the heat energy that fuel combustion is produced is fully utilized.
