Description
Technical field
The utility model relates to a kind of heat-exchange device, particularly a kind ofly is used for the heat exchange of heat pipe that waste heat utilizes again.
Background technology
In the prior art, a kind of integrated thermal heat exchanger is arranged, form by the many single heat pipes of many rows multiple row.Its heat pipe one end is arranged in the condensation chamber, the other end is arranged in the evaporation cavity, rely on median septum that condensation chamber and evaporation cavity are separated, median septum is passed at the middle part of heat pipe, and being provided with sealing device with the coaxial setting of heat pipe with the median septum contact site, although in the prior art, two kinds of gases can be accomplished not gang up mutually, but from structural principle, still have the potential safety hazard that the user is worried, ablating as median septum makes flue gas gang up mutually with coal gas.
In the prior art, also has a kind of separated heat pipe heat exchanger, comprise condensation chamber casing and evaporation cavity casing, condensation chamber casing and evaporation cavity casing are separatedly installed, each casing adds housing by many heat extractions pipe pipe group and forms, and the tedge of dependence outer setting and down-comer link up the heat pipe of condensation chamber casing and evaporation cavity casing.The absolute altitude of condensation chamber casing is much larger than the absolute altitude of evaporation cavity casing, can make just that the working medium in the heat pipe heat is subjected to the steam of thermal evaporation to flow to condensation chamber along tedge in the evaporation cavity.Working substance steam condensed condensate liquid in condensation chamber is back in the every heat extraction pipe of the evaporation cavity pipe group along down-comer.Although the separated heat pipe heat exchanger since condensation chamber casing and evaporation cavity casing in the large space scope, isolate, security is good, but it exists, and radiation loss is big, metal consumption is big, occupy spatial volume and area is big, pipeline structure is complicated, on-the-spot installations, working medium can, suppress that difficulty is big, the engineering time is long, and the passivating film corrosion is impaired and cause the life-span than shortcomings such as weak points in the pipe.
The utility model content
The purpose of this utility model provides a kind separated heat pipe heat exchanger, and its body structure and effect are similar to the separated heat pipe heat exchanger, have better security.
The purpose of this utility model is achieved in that a kind separated heat pipe heat exchanger, comprise the condensation chamber casing, evaporation cavity casing and heat pipe, the heat pipe upper end is passed in the upper perforated plate that is provided with in the condensation chamber, the lower perforated plate that is arranged at the evaporation cavity bottom is passed in the lower end of heat pipe, the middle part of heat pipe and heat pipe are coaxially arranged with double end external screw thread sealing shroud, the condensation chamber bottom is provided with median septum, the evaporation cavity top is provided with down median septum, on, isolated between the following median septum through air barrier, double end external screw thread sealing shroud two ends are passed respectively, the stepped bore that is provided with on the following median septum, the path section of stepped bore and double end external screw thread sealing shroud external diameter are suitable, double end external screw thread sealing shroud two ends are respectively equipped with the suitable locking nut of big footpath section with stepped bore, described stepped bore, be provided with the soft graphite sealing ring in the annular space that forms between locking nut and the double end external screw thread sealing shroud.
In the utility model use, in heat pipe, be encapsulated into heat transfer medium, feed high-temperature flue gas in the evaporation cavity casing, feed the coal gas or the air of low temperature in the condensation chamber casing, during work, the heat transfer medium evaporation of absorbing heat in the evaporation cavity casing is risen and to be entered heat pipe top, then in the condensation chamber casing heat release and condensing reflux to the heat pipe bottom, the heat transfer medium heat release makes coal gas or atmosphere temperature rising, reaches the purpose that waste heat utilizes again; The utility model is realized sealing by screwing upper and lower locking nut with the distortion of extruding soft graphite, make evaporation cavity and condensation chamber realize two way seal, the setting of air barrier is isolated condensation chamber, evaporation cavity mutually, realized being similar to the technique effect of separated heat pipe heat exchanger, in the use, can not gang up mutually between flue gas and coal gas or the air, have good security; Because do not have outside heat dissipation pipeline, the utility model radiation loss is little, the heat exchange efficiency height, its metal consumption is few, occupy spatial volume and area is little; The utlity model has long service life, good seal performance, safe and reliable, be easy to advantages such as consolidation.Can be applicable to the place that various fume afterheats utilize again.
