Description
Technical field
The utility model relates to low-temperature flue gas afterheat generating system in a kind of vertical heat pipe organic media evaporation, belongs to the energy and environment technical field.
Background technology
At present; Middle low-temperature flue gas afterheat generating system adopts the tedge and the down-comer of boiler to carry out heat exchange, and it can take place to corrode and break after using certain hour because of the Long contact time with flue gas; Organic working medium is leaked in the flue; Cause the waste of organic working medium and the decline of heat exchange efficiency, and the replacing of the tedge of boiler and down-comer is very difficult, is unfavorable for the normal operation and the cost control of system.
Heat pipe is the primary element of heat exchange of heat pipe, from its outward appearance, and common pipe that fin or non-finned are arranged normally, its primary structure characteristics show in the pipe.Heat pipe is made up of shell, capillary porous material (tube core) and vapor chamber (steam channel).See that from heat transfer conditions heat pipe can be divided into evaporator section, adiabatic section and condensation segment three parts vertically.During work, evaporator section makes the hydraulic fluid evaporation in its capillary materials because of being heated, and the steam flow condensation segment makes steam condense into liquid owing to receive cooling here, and liquid leans on the capillary force effect to flow back to evaporator section along porous material again.So circulate endlessly, heat reaches the other end by an end of heat pipe.Because the latent heat of vaporization is big, so under the minimum temperature difference, just can reach condensation segment to great amount of heat from the evaporator section of heat pipe.
The tube core of heat pipe is a kind of capillary structure of being close to inner wall of tube shell, is close to inwall to reduce thermal contact resistance with multiple layer metal silk screen or fiber, cloth etc. with the lining form usually, and lining also can be made up of porous ceramics or sintering metal.The tube core of function admirable should have:
enough big capillary pumped pressure head;
less liquid flowing resistance, existing higher permeability;
good heat transfer characteristic promptly has less radially thermal resistance.Thereby; The structure of tube core has a variety of, is broadly divided into following several types:
is close to the individual layer and the multilayer web-roll core of tube wall;
sintered powder tube core, it is to be formed at the inside pipe wall face by the metal dust of certain order number or woven wire sintering;
axial slot formula tube core; It is to open axial stria at inner wall of tube shell; So that capillary pressure head and liquid reflux channel to be provided; The cross sectional shape of groove can have rectangle, and is trapezoidal etc. multiple;
combined die.General tube core often can not be taken into account capillary suction force and permeability simultaneously, and combined die can be taken into account capillary force and permeability, thereby obtains high axial heat conduction ability, and the radially thermal resistance of most of tube cores is very little.He is basically the tube core separated into two parts, and a part plays the capillary swabbing action, and a part plays the liquid reflux channel effect.
The working solution of heat pipe will have the higher latent heat of vaporization, thermal conductivity factor, suitable saturation pressure and boiling point, lower viscosity and good stable property.Hydraulic fluid also should have the bigger surface tension and the ability of wetting capillary structure, makes capillary structure and produce necessary capillary force to the working solution effect.Working solution can't produce dissolution to capillary structure and tube wall, destroys capillary structure otherwise dissolved material will be accumulated in evaporator section.
