Description

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

Technical field

The present invention 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.

Summary of the invention

The present invention has 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.

Body of heater, burner hearth and traveling-grate stoker have been the present invention includes, burner hearth is positioned at the bottom of body of heater, traveling-grate stoker is arranged in burner hearth, and the present invention also includes first heat exchanger and second heat exchanger, and first heat exchanger and second heat exchanger constitute body of heater, first heat exchanger is positioned at upper furnace, second heat exchanger is positioned at the first heat exchanger top, and first heat exchanger is made up of superconductor and at least one group of smoke pipe, and every group of smoke pipe has a smoke pipe at least, 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 of the present invention and principle 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 by smoke pipe, because smoke pipe is immersed in the superconductor, so, heat in the flue gas passes to superconductor by 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 invention has the beneficial effects as follows: the thickness pipe is immersed in the superconductor, and superconductor absorbs the heat of flue gas fully, the heat energy utilization rate height of fuel; 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 present invention is by body of heater 1, burner hearth 2 and traveling-grate stoker 3 are formed, burner hearth 2 is positioned at the bottom of body of heater 1, traveling-grate stoker 3 is arranged in burner hearth 2, first heat exchanger 4 and second heat exchanger 5 constitute body of heater 1, first heat exchanger 4 and second heat exchanger 5 are 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, first heat exchanger 4 is made up of superconductor 41 and at least one group of smoke pipe, every group of smoke pipe has a smoke pipe 42 at least, and 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 the circulating water pipe 52 and the gaseous state superconductor 51 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 described second heat exchanger 5 is decided according to actual conditions.

As depicted in figs. 1 and 2, in the present embodiment, the A that arranges about first heat exchanger 4 has, B, C, D, E, seven groups of smoke pipes of F and G, 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, the front end of A group smoke pipe and B group smoke pipe is communicated with by the first outside ash door 43, the rear end of B group smoke pipe and C group smoke pipe is communicated with by the second outside ash door 44, the front end of G group smoke pipe and F group smoke pipe is communicated with by the 5th outside ash door 47, the rear end of F group smoke pipe and E group smoke pipe is communicated with by the 4th outside ash door 46, 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 by 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, the heat that produces is directly to the superconductor heating in first heat exchanger 4 of top, the flue gas that burning produces is discharged by smoke pipe 42, 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 by thickness pipe 42, and the heat energy that fuel combustion is produced is fully utilized.

After superconductor 41 is heated, gasification rapidly, gaseous state superconductor 51 enters into second heat exchanger 5 rapidly and carries out heat exchange with the circulating water pipe 52 that coils, and with heat transferred recirculated water, the superconductor that condenses is directly got back in first heat exchanger 4.
