Description
Technical field
The utility model relates to field of heat exchangers, specifically a kind of heat pipe wind-warming unit.
Background technology
At extremely frigid zones, boiler winter operation needs to utilize steam air heater to carry out preheating to inlet air of boiler, if use the electric heater units such as resistance wire to carry out preheating, then can cause waste of energy.For boiler, the heat of its tail gas may be used for the preheating of air inlet, and therefore, often use the steam air heater of heat exchange type at present, wherein modal is heat pipe wind-warming unit.Heat pipe is a kind of heat transfer element with high heat conductivility, and it has the advantage such as high thermal conductivity, good isothermal by carrying out transferring heat at the evaporation and condensation of Totally enclosed vacuum intraductal working medium.The operation principle of heat pipe wind-warming unit is: heat pipe heat side absorbs waste-gas heat, and heat is passed to intraluminal fluid state working medium, to evaporate with the formal transformation of boiling for steam after working medium heat absorption, steam rises to cold side under differential pressure action, condense into liquid simultaneously and release the latent heat of vaporization, heat passes to the cold fluid of cold side, and in-tube condensation liquid relies on gravity reflux to heat side.
In concrete use, there is following defect in existing heat pipe wind-warming unit: 1) tube surface is main heat-transfer surface, and it is smooth cylinder, and heat exchange area is little, and heat transfer effect is bad; 2) contain sulfide and nitride in flue gas, acid etching is caused on easy opposite heat tube surface, causes heat pipe to reduce service life, changes frequent; 3) both ends of heat pipe are separately positioned in heat-absorbing chamber and heat release chamber, and heat-absorbing chamber and heat release chamber are opened by baffle for separating, and heat pipe is directly inserted on dividing plate, and this kind of mounting means is difficult to ensure sealing property and do not utilize heat pipe to change.
Utility model content
The technical problems to be solved in the utility model is to provide that a kind of good effect of heat exchange, wear resistant corrosion resistant are strong, heat pipe disassembling, assembling and replacing heat pipe wind-warming unit easily.
For solving the problems of the technologies described above, heat pipe wind-warming unit of the present utility model comprises superposed heat release chamber, heat-absorbing chamber in bottom and the dividing plate be horizontally installed between heat-absorbing chamber and heat release chamber, the many heat pipes longitudinally arranged are installed at dividing plate is embarked on journey interval in column, the two ends in heat release chamber offer cold wind import and cold wind outlet respectively, the two ends of heat-absorbing chamber offer gas approach and exhanst gas outlet respectively, its design feature is that the middle part of described heat pipe is arranged on dividing plate, the upper tubular section of heat pipe and lower tubular section arrange helical fin respectively, helical fin, the upper tubular section of heat pipe and lower tubular section are all coated with anticorrosive coat.
On described dividing plate, multiple through hole is offered at interval, and through hole is the shoulder hole that top is macropore, bottom is aperture, and the middle part of heat pipe is fixed with the chuck adapted with shoulder hole macropore, and chuck is arranged in shoulder hole macropore.
Between the middle part of described heat pipe and chuck, sealing ring is set.
The bottom surface of described chuck arranges seal washer.
Described anticorrosive coat is glassy layer.
Described anticorrosive coat is ceramic layer.
The beneficial effects of the utility model are: by establishing helical fin on heat pipe, heat exchange area can be increased, thus make heat transfer effect better, the surface of heat pipe and helical fin establish glassy layer or ceramic layer as anticorrosive coat, increase surface abrasion resistance to damage and corrosion resistance, thus increase heat pipe service life, reduce heat pipe replacement frequency; Heat pipe utilizes the structure installment of chuck and shoulder hole on dividing plate, and disassembling, assembling and replacing is convenient; Seal washer and sealing ring are set, the isolation effect between heat-absorbing chamber and heat release chamber can be ensured, avoid flue gas to be mixed into boiler air inlet.In sum, the utility model has good effect of heat exchange, wear resistant corrosion resistant is strong, heat pipe disassembling, assembling and replacing is convenient and the advantage of good seal performance.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A portion structure for amplifying schematic diagram in Fig. 1;
Fig. 3 is the structural representation of the wherein portions of heat pipe in the utility model;
