Description
Technical Field
The utility model belongs to flue gas waste heat exchanger field, more specifically say, relate to a novel pipeline formula fin spiral-flow heat exchanger.
Background
A large number of boilers are used in the steel industry, a large amount of smoke can be generated by the boilers, a large amount of waste heat can be taken away by the smoke, and resource waste is caused. So technicians are always studying the reuse of the flue gas waste heat.
The boiler combustion needs to enter a large amount of air, and the direct entering of cold air can cause resource waste. At present, a fin self-preheating burner heated by smoke waste heat is generally used, and air with a certain temperature can enter the burner. The air after the waste heat can greatly improve the combustion temperature in the boiler.
After long-term use, the heat exchange efficiency of the existing fin self-preheating burner is low, the utilization rate is less than 10%, the use cost is high, the temperature of the discharged flue gas is high, the waste heat is not fully utilized, and waste energy is caused.
In view of this, technical personnel have developed a novel pipeline formula fin spiral-flow heat exchanger, have improved the temperature of the air that the nozzle got into by a wide margin, and the temperature of flue gas is not high moreover, and the heat exchange is abundant, improves energy utilization, reaches energy-conserving effect, and this technique need not change the nozzle simultaneously, practices thrift the cost.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims to provide a novel tubular fin spiral-flow heat exchanger has improved the temperature of the air that the nozzle got into by a wide margin, and the temperature of flue gas is not high moreover, and the heat exchange is abundant, improves energy efficiency, reaches energy-conserving effect, and the nozzle need not be changed to this technique simultaneously, practices thrift the cost.
In order to achieve the above purpose, the utility model provides a following technical scheme:
the utility model provides a novel tubular fin spiral-flow heat exchanger, corresponding with flue gas pipeline, its characterized in that: comprises an air inner pipe, an air outer pipe and a flue gas pipeline; the air inner pipe penetrates through and is arranged in the smoke pipeline, and the smoke pipeline penetrates through and is arranged in the air outer pipe; the lower end of the air inner pipe penetrates through the side face of the flue gas pipeline, and the air inner pipe is communicated with the air outer pipe; the outer surface of the flue gas pipeline is provided with a plurality of fins which are hollow and communicated with the air outer pipe; the inside of air inner tube is provided with a spiral helicine spinning disk, and the spinning disk setting is intraductal and both ends communicate flue gas pipeline respectively in the air.
As an optimized technical scheme, two ends of the flue gas pipeline are respectively provided with a connecting flange; a connecting flange is arranged at the air inlet end of the air outer pipe; and a connecting flange is arranged at the air outlet end of the air inner pipe.
As an optimized technical scheme, a buffer cavity is installed on the side edge of the lower portion of the flue gas pipeline, the buffer cavity is not communicated with the flue gas pipeline, and two ends of the buffer cavity are respectively communicated with the air inner pipe and the air outer pipe.
As an optimized technical scheme, a plurality of fins are arranged on the outer surface of the air inner pipe, the fins are designed to be hollow, and the fins are communicated with the air inner pipe.
Since the technical scheme is used, compare with prior art, the utility model discloses utilize air outer tube and fin to carry out the heat transfer for the first time, reuse air inner tube, spinning disk and fin carry out the heat transfer for the second time, the secondary heat transfer can fully carry out the heat exchange, has improved the temperature of the air that the nozzle got into by a wide margin, and the temperature of flue gas is not high moreover, and the heat exchange is abundant, improves energy utilization and rates, reaches energy-conserving effect, and this technique need not change the nozzle simultaneously, practices thrift the cost.
The present invention will be further explained with reference to the drawings and examples.
