Abstract
The utility model provides a novel energy saving air heat exchanger which comprises a blowing machine, a boiler, a cold air channel, a hot air channel, a cold air inlet is arranged on the right side of the top of the boiler, and a hot air outlet is arranged on the right side of the top of the boiler. The novel energy saving air heat exchanger further comprises an air heat exchanging device which includes two parallel cylindrical cold air tanks. The middle portions of the left cold air tank and the right cold air tank are communicated, and the peripheries of the two cold air tanks are respectively covered by a layer of hot air pipe. The lower end of the right cold air tank is connected with the blowing machine through the cold air channel, the top of the left cold air tank is connected with the cold air inlet on the top of the boiler, the hot air pipe is connected with the hot air outlet which is on the left side of the boiler through the hot air channel, and an opening is formed in the other end of the hot air pipe. The novel energy saving air heat exchanger has the advantages that the structure is simple, by utilizing the air heat exchanger, the temperature of the hot air can be reduced from 300 degrees to 120 degrees, the temperature of the cold air can be increased from 20 degrees to 200 degrees, the gas volume can be saved by 15 percents, energy-saving effect is remarkable, and the burning environment and conditions in the furnace can be improved effectively.
Description
Technical field
The utility model relates to the brethaid technical field, relates in particular to a kind of with the novel energy-conserving air heat exchanger of burnt gas with the combustion air preheating.
Background technology
At present, various boiler furnace burning combustion airs all adopt the outer air of body of heater, and directly enter in the burner hearth.Yet winter, outdoor temperature was lower, can absorb a large amount of heats when Cryogenic air enters burner hearth, reduce the ignition temperature in the burner hearth, not only waste Coal Energy Source, increase coal consumption, affect efficiency of combustion, and destroyed normal burning condition and burning situation in the burner hearth, reduced burning quality.In addition, the flue gas that boiler is discharged directly by smoke stack emission in atmosphere, insufficient because of heat exchange, cause heat-energy losses.
The utility model content
Problem to be solved in the utility model provides a kind of novel energy-conserving air heat exchanger that can improve the thermal efficiency, energy savings.
The technical solution of the utility model is as follows: a kind of novel energy-conserving air heat exchanger, comprise air blast, boiler, the cold air road, the hot gas road, right side, described boiler top is provided with the cold air import, described boiler left side is provided with heat outlet, it is characterized in that: also comprise air heat-exchanging device, described air heat-exchanging device comprises two cylindrical cold air buckets side by side, be respectively left side cold air bucket and right side cold air bucket, described left side cold air bucket and cold air bucket middle part, right side UNICOM, the peripheral parcel of described two cold air buckets one deck hot gas duct, cold air bucket lower end, described right side is connected with air blast by the cold air road, upper end, cold air road, described left side is connected with the cold air import of boiler top by the cold air road, described hot gas duct is connected described hot gas duct other end opening by the hot gas road with boiler left side heat outlet.
Further, described hot gas duct diameter is 2-4cm, and described hot gas duct closely is coiled in two cold air bucket outsides.
The beneficial effects of the utility model are: the utility model is simple in structure, can be reduced to 120 ℃ by 300 ℃ through air heat-exchanging device hot gas, cold air can be elevated to 200 ℃ by 20 ℃, can save 15% gas quantity, energy-saving effect is remarkable, can effectively improve burning situation and condition in the burner hearth.
