Description
Technical field
The utility model belongs to metallurgical engineering technical field, particularly relates to a kind of heat exchanger tube.
Background technology
In a lot of practical applications of metallurgical engineering technology, usually need to heat or heat treatment samples such as metal material, nonmetallic materials or workpiece, and test accordingly.A kind of method conventional is at present heated workpiece to be processed by gas-fired heater.But general gas-fired heater is interior is all generally directly be blown in heating furnace by air blast for combustion-supporting air, the waste gas with very high heat that burning produces simultaneously is all generally direct discharge, or directly enter emission-control equipment to process, such one side causes very large waste to the energy, and the waste gas of high temperature also easily produces potential safety hazard on the other hand.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this utility model is to provide a kind of heat exchanger tube, thus effectively reduces EGT, avoids producing potential safety hazard; Effective raising enters the air themperature in heating furnace, reduces energy waste.
In order to realize above-mentioned object, the utility model have employed following technical scheme:
A kind of heat exchanger tube, comprise inner and outer tubes, described interior pipe and outer tube are hollow steel pipe, arrange every dead level between interior pipe and outer tube, and the bottom of described interior pipe is provided with into mouth, and the top of interior pipe is provided with outlet flue; Described outer tube is provided with air inlet and air outlet; Evenly be provided with multiple fin between the outer wall of described interior pipe and the inwall of outer tube, thus form multiple gas channel.Waste gas after heating furnace burning is discharged by the outlet flue of interior pipe, air blast is connected with the air intake vent of heat exchanger tube, air is blown into heating furnace by the air outlet of outer tube, exchange heat is carried out between the two by fin and inner pipe wall, the EGT of discharging is made to reduce on the one hand, improve the temperature of the air entered in heating furnace on the other hand, reduce thermal loss and energy waste.
As preferably, described air inlet is arranged on the bottom of outer tube, and air outlet is arranged on the top of outer tube.
As preferably, described air inlet is arranged on the top of outer tube, and air outlet is arranged on the bottom of outer tube.
As preferably, described inner and outer tubes roll by steel plate and are welded.
As preferably, described air inlet is provided with air inducing circle.Air inducing circle is set, makes air inlet smooth, more concentrated during inlet air, also can play the effect reducing noise simultaneously.
Compared with prior art, the beneficial effects of the utility model are: by the structural design that heat exchanger tube is special, waste gas after heating furnace is burnt is by the discharge of pipe in heat exchanger tube, air blast is blown into heating furnace air by the air outlet of heat exchanger tube outer tube, exchange heat is carried out between the two by fin and inner pipe wall, make the EGT of discharging reduce on the one hand, improve the temperature of the air entered in heating furnace on the other hand, reduce thermal loss and energy waste.
In addition, by arranging air inducing circle, make air inlet smooth, more concentrated during inlet air, also can play the effect reducing noise simultaneously.

Fig. 1 is the structural representation that heat exchanger tube coordinates with air blast.
Fig. 2 is the structural representation of heat exchanger tube.
Fig. 3 is the top view of heat exchanger tube.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is made a detailed explanation.
A kind of heat exchanger tube as shown in FIG. 1 to 3, comprises interior pipe 3 and outer tube 4, and described interior pipe 3 is hollow steel pipe with outer tube 4, and interior pipe 3 is rolled by 1Cr13 corrosion resistant plate and is welded, and outer tube 4 is rolled by Q235 steel plate and is welded.The diameter of interior pipe 3 is between interior pipe 3 and outer tube 4, because diameter is different thus formed every dead level (figure does not mark).Be provided with into mouth 5 in the bottom of interior pipe 3, the top of interior pipe 3 is provided with outlet flue 6; The upper end of outer tube 4 is provided with air inlet 7, and the lower end of outer tube 4 is provided with air outlet 8, and the air inlet 7 of outer tube 4 upper end is connected with air blast 1, and the air outlet 8 of outer tube 4 lower end passes into the inside of heating furnace by pipeline; Between the outer wall and the inwall of outer tube 4 of interior pipe 3, be evenly provided with multiple by fin 9, described fin 9 be made up of Q235 steel plate.Fin 9 be arranged between interior pipe 3 and outer tube 4 in dead level, and and between interior pipe 3 and outer tube 4, form multiple gas channel 10.
When mounted, air inlet 7 realizes being flexible coupling by canvas 12 and air blast 1.Canvas 12 is adopted to be flexible coupling, with low cost, implement simple, effectively can absorb the vibrations produced when air blast 1 works, effectively prevent because vibrations cause pipeline to leak in junction.The air inducing circle 11 of inner wall smooth is provided with at air inlet 7 place.Arrange air inducing circle 11, canvas 12 can better be coordinated with air inlet 7, simultaneously due to the inner wall smooth of air inducing circle 11, when making inlet air, air quantity is more concentrated, also can play the effect reducing noise simultaneously.
Time in real work, the waste gas after heating furnace burning enters in interior pipe by the mouth 5 that enters of interior pipe 3, discharges eventually through outlet flue 6.In the process, the waste gas of high temperature is by inner pipe wall and fin heat temperature raising.Air blast 1 air by the air inlet 7 of outer tube 4 be blown between outer tube 4 and interior pipe 3 in dead level, after air contacts with fin with inner pipe wall, through heat transfer, the temperature of air rises, air after final heating enters inside heating furnace by air outlet 8, by this structural design, make high-temp waste gas and air, at inner pipe wall and fin place, exchange heat occur, the EGT of discharging is made to reduce on the one hand, improve the temperature of the air entered in heating furnace on the other hand, reduce thermal loss and energy waste.
Above content described in this description is only to the explanation of the utility model example.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment; only otherwise depart from the content of the utility model description or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.The such as position of air inlet 7 and air outlet 8 arrange can be adjusted to air outlet 8 upper, air intake vent 7 under.
