Energy -saving heat exchanger can effectively improve heat exchange efficiency, increase hot exchange area for the heat exchange is carried out to gaseous fully the contact with microthermal air of waste heat, effectively reduces the gaseous temperature of waste heat, reduces and discharges the pollution that causes the environment, carries the high energy utilization efficiency, and is energy -concerving and environment -protective, reduction in production cost.
Description
Technical field
The utility model relates to heat-exchange device, particularly relates to a kind of energy-saving heat exchanger.
Background technology
The green-keeping machine hot blast drum-type that current most of tealeaves factory uses, be connected with hot-blast stove by cylinder type water-removing machine, the dry-heat air utilizing hot-blast stove to supply completes to tealeaves.The emission gases of carrying out completing after process still has a large amount of waste heats, direct discharge is big for environment pollution, energy waste is large, therefore the waste heat gas of discharge after the process that completes is used for carrying out preheating to the input air of hot-blast stove, thus the power consumption of hot-blast stove can be reduced, reduce Tea Production cost.Traditional at present to carry out the heat exchanger effectiveness of the heat exchanger of heat exchange for waste heat gas and input air low, and effectively the heat of waste heat gas can not be passed to input air, energy-saving effect is not good, and the temperature of the gas of final discharge is still higher, contaminated environment.
Utility model content
The technical assignment of technical problem to be solved in the utility model and proposition improves prior art, there is provided a kind of energy-saving heat exchanger, the heat exchanger effectiveness solving heat exchanger in current technology is low, and energy-saving effect is poor, the temperature of emission gases is high, the problem of contaminated environment.
For solving above technical problem, the technical solution of the utility model is:
A kind of energy-saving heat exchanger, comprise outer tube and interior pipe, it is characterized in that, in described outer tube, interior pipe is set, and the two ends of outer tube are provided with capping, the two ends of interior pipe penetrate out capping, form confined space between outer tube wall and outer wall of inner tube, the outer wall of described interior pipe is provided with fin, and fin helically structure vertically, the outer rim of fin abuts in outer tube wall, and the two ends of outer tube are respectively arranged with air inlet and gas outlet.Energy-saving heat exchanger described in the utility model utilizes the spiral fin of outer wall of inner tube that the space between interior pipe and outer tube is separated into spiral passage, the waste heat gas entered from the air inlet of outer tube is along spiral passage flow, improve the heat-exchange surface sum processing time, make waste hot air body fully can carry out heat exchange with the Cryogenic air passed through in interior pipe, improve heat exchanger effectiveness, thus the heat of waste heat gas is passed to Cryogenic air to the greatest extent to greatest extent, reduce exhaust temperature, reduce the pollution to environment, air after preheating only needs less energy consumption just can reach required temperature in hot-blast stove, reduce the production cost of Tea Processing, energy-conserving and environment-protective, and the Cryogenic air heated directly does not contact with waste heat gas, guarantee the cleanliness factor of the air after preheating, avoid polluting tealeaves, ensure the quality of tealeaves.
Further, described outside pipe is set with heat insulation layer, prevents the heat of preheating gas outwards to scatter and disappear from outer tube, improves the utilization ratio of heat.
Further, between described capping and outer tube, be provided with sealing ring, avoid waste heat gas to leak in pipe outside, guarantee that waste heat gas fully fully carries out heat exchange with the Cryogenic air passed through in interior pipe.
Further, described interior pipe adopts copper pipe, and fin is made of copper, the good heat conductivity of copper, and the heat of waste heat gas can be made to pass to air to be heated to the greatest extent to greatest extent, improves heat exchanger effectiveness.
Further, the two ends of described interior pipe are provided with flange, and convenient connection, improves sealing.
Compared with prior art, the utility model advantage is:
Energy-saving heat exchanger described in the utility model effectively can improve heat exchanger effectiveness, increase heat exchange area, waste heat gas is fully contacted with the air of low temperature and carries out heat exchange, the temperature of effective reduction waste heat gas, reduce discharge pollution on the environment, improve efficiency of energy utilization, energy-conserving and environment-protective, reduce production cost; The utility model structure is simple, is easy to manufacture, and load and unload easy to maintenance, low cost of manufacture, business efficiency is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
