Technical field
The utility model relates to a kind of heat exchanger, relates in particular to a kind of mainly surpassing under 1000 ℃ the operating mode in temperature use the radiant type high-temperature heat-exchanging that adopts radiation mode to carry out heat exchange.
Background technology
Advocate under the overall background of low-carbon economy in current country, heat exchanger is being indispensable equipment aspect minimizing fuel consumption and the energy-saving and emission-reduction.In general, temperature in the heat exchange more than 700 ℃ mainly take radiant heat transfer as main, and 700 ℃ with next mainly be convection heat transfer' heat-transfer by convection, with regard to gas-gas heat exchange field, the various forms of heat exchangers that occurred at present are such as heat pipe-type, finned, what plate type heat exchanger was mainly taked is the mode of heat convection, but wherein can with the equipment more than the dielectric heating to 700 ℃ seldom, mainly contain many-sided reason.At first be material thermal stress issues at high temperature, weld seam usually occur at high temperature by the phenomenon of drawing crack; Next is the restriction of metal material attribute, and under hot conditions, especially after working temperature surpassed the allowable temperature of material itself, the strength of materials can sharply descend, and stabilization of equipment performance descends; In addition, the oxide etch under worst hot case also is the key factor of restriction equipment performance.For example Chinese patent application file 94244784.0 discloses " a kind of telescopic coal-fired indirect-heating hot air stove ", body of heater by a plurality of cross section radiuses different but central axis all overlapped cylindrical metal cylinder form, by guide shell and radiant panel are set, utilized to a certain extent hyperthermia radiation heat, eliminate heat exchanging corner, but the deficiency that this equipment exists is, do not consider that thermal expansion that equipment exists causes the problem of weld seam drawing crack under worst hot case, and this equipment requires high to material behavior, need material to keep sufficient intensity under worst hot case.Again such as " indirect hot air stove " mentioned in the patent 200320110982.7 although this high-temperature service has expansion joint at the central interior channel setting, but when air is heated to more than 500 ℃, the metal material of two media side all can have larger thermal stress, and this equipment is not adopted an effective measure for thermal expansion problem outside under the worst hot case, although equipment has adopted the high temperature stainless steel inner bag in addition, has certain corrosion resistance, but only rely on the characteristic of stainless steel itself can not effectively solve the high temperature oxidation and corrosion of metal material, and adopt in a large number high temperature stainless steel also to cause the increase of cost.Therefore, a kind of high-temperature heat-exchanging of exigence satisfies the needs of actual environment.
Summary of the invention
The equipment strength decreased that the utility model is prone under worst hot case for heat exchanger in the prior art just, the problems such as corrosion-deformation and heat-transfer effect are poor, the use of optimal design and high thermal conductivity coefficient nonmetallic materials by device structure, provide a kind of high temperature resistant, anticorrosive, heat transfer efficiency is high, the relatively simple radiant type high-temperature heat-exchanging of structure.
The technical solution of the utility model is as follows, a kind of radiant type high-temperature heat-exchanging, comprise heat exchanger body and the shell that is arranged on this body exterior, it is characterized in that described body comprises inner barrel and jacket cylinder, the bottom of described body is provided with the high-temperature medium import, the top of body is provided with the high-temperature medium outlet, one side of high-temperature medium import is provided with the cryogenic media outlet, one side of high-temperature medium outlet is provided with the cryogenic media import, and described high-temperature medium import department is provided with the carborundum thermal insulation layer of high thermal conductivity coefficient.
As a kind of improvement of the present utility model, described body comprises central high-temperature medium passage and around the cold medium channel around it, central high-temperature medium passage is mainly take radiation heat transfer as main, and cold medium channel is mainly take heat convection as main.According to the heat convection principle, as can be known heat output Φ=
=
, at temperature and pressure
In the certain situation of heat exchange area A, owing to having adopted the high thermal conductivity coefficient castable, can guarantee the thermal conduction resistance of castable
Smaller, same because the heat transfer of high-temperature flue gas side is provided with the radiation deflector take radiation heat transfer as the master and at centre gangway, increased hot side heat transfer coefficient
Value, can guarantee the high temperature side thermal resistance
Smaller, and cold-side fluid is mainly in the mode of heat convection as main.
As a kind of improvement of the present utility model, described inside and outside cylindrical shell is provided with expansion joint, adopts two expansion joints can effectively solve the weld seam drawing crack problem that the thermal stress of metal causes under the worst hot case, and expansion joint can be set to single ripple or many ripples according to operating mode.
As a kind of improvement of the present utility model, be provided with heat exchange fin in the described cold medium channel, this heat exchange fin the heat exchange area that has increased cold medium channel is set
And the flow-disturbing of further strengthening cold side improves
Value, thereby reduce the thermal resistance of cold side
, owing to having adopted above-mentioned these measures further to improve the heat transfer efficiency of heat exchanger integral body.
For prior art, radiant type high-temperature heat-exchanging advantage is as follows: simple in structure, and modern design, this heat exchanger by the parts of complexity, only is not to change for structure on the basis of existing technology, has just solved a difficult problem of the prior art; Cost is lower, and is safe and reliable, easy to operate; Heat transfer efficiency is high, and this heat exchanger can use under ultra-high temperature condition.
