Abstract
The utility model discloses a heat exchange device for high-temperature flue gas heat exchange, and aims to provide a heat exchange device which is convenient to use and high in heat exchange efficiency for high-temperature flue gas heat exchange. The heat exchange device comprises a sealed shell, an inner container and a base, wherein the inner container is arranged in the shell, and the base supports the inner container. A gas inlet pipe is arranged on the lower portion of the shell, a gas outlet pipe is arranged on the upper portion of the shell, a flue gas channel is formed in a cavity between the inner container and the shell, a separator spirally rising along the outer wall of the inner container is arranged in the flue gas channel, the spiral outside of the separator is hermetically connected with the inner wall of the shell, and the flue gas channel forms a spirally rising channel by the aid of the separator. The circulation path of high-temperature flue gas in the flue gas channel can be increased by the spirally rising channel, and the heat exchange efficiency of the high-temperature flue gas and the inner container is improved.
Description
Technical field
The utility model relates to a kind of heat transmission equipment, especially relates to a kind of heat-exchanger rig for high-temperature flue gas heat exchange.
Background technology
At present, for burning, the main equipment of roasting can produce a large amount of high-temperature flue gas in process of production, in order to improve the heat utilization efficiency of heat energy that fuel combustion produces, conventionally use heat-exchanger rig to carry out further heat exchange absorption to high-temperature flue gas, the thermal energy transfer of high-temperature flue gas, to the medium of heat-exchanger rig, is realized to the absorption recycling of high-temperature flue gas heat energy.
Existing heat-exchanger rig mainly by absorbing the inner bag of transferring heat energy, the airtight housing that holds inner bag forms.In use, because the supporting role of inner bag by support is arranged in housing, common support there will be distortion in the hot environment of high-temperature flue gas, make inner bag can not get effective support, cause the distortion of heat-exchanger rig structure, even go out sealing and decline, affect the normal use of heat-exchanger rig.Between the inner bag of this kind of heat-exchanger rig and housing, form exhaust gases passes, high-temperature flue gas is with very short path by the exhaust gases passes of heat-exchanger rig simultaneously, and the efficiency of heat exchange is not high.
Utility model content
The utility model has overcome shortcoming of the prior art, and the heat-exchanger rig for high-temperature flue gas heat exchange that a kind of heat exchange efficiency is high is provided.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of heat-exchanger rig for high-temperature flue gas heat exchange, comprises airtight housing, is arranged at inner bag in housing and supports the base of inner bag; The bottom of described housing is provided with air inlet pipe, and top is provided with escape pipe; Cavity between described inner bag and housing forms exhaust gases passes, is provided with along the spiralling separator of inner bladder outer wall in described exhaust gases passes, and the spiral outside of separator and inner walls are tightly connected; Separator makes exhaust gases passes form spiralling passage.
Preferably, described base employing refractory brick is piled up and is formed.
Preferably, between the refractory brick that described base adopts, leave gap.
Preferably, described separator is piled up and is formed by refractory brick.
Preferably, described inner bag is made by aluminium alloy.
Compared with prior art, the utlity model has following advantage:
(1) the utility model, by being provided with in exhaust gases passes along the spiralling separator of inner bladder outer wall, makes exhaust gases passes form spiralling passage by separator.After high-temperature flue gas is entered by air inlet pipe, along spiralling channel flow and arrive escape pipe and discharge.This process has increased the circulation path of high-temperature flue gas in exhaust gases passes, realizes the sufficient heat exchange of high-temperature flue gas and inner bag, effectively improves the heat-exchange capacity of this heat-exchanger rig.
(2) base employing refractory brick of the present utility model is piled up and is formed, and leaves gap between refractory brick.Refractory brick has high temperature resistant indeformable feature, support inner bag that can be stable.And gap between refractory brick can make high-temperature flue gas pass through, high-temperature flue gas is fully contacted with the bottom of inner bag, improve the efficiency of heat exchange.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of an embodiment of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Shown in Fig. 1, for the heat-exchanger rig of high-temperature flue gas heat exchange, comprise airtight housing 1, be arranged at inner bag 2 in housing 1 and support the base 3 of inner bag 2; The bottom of described housing 1 is provided with air inlet pipe 4, and top is provided with escape pipe 5; Cavity between described inner bag 2 and housing 1 forms exhaust gases passes 6, is provided with along the spiralling separator 7 of inner bag 2 outer wall in described exhaust gases passes 6, and the spiral outside of separator 7 is connected with housing 1 inner wall sealing; Separator 7 makes exhaust gases passes 6 form spiralling passage.
Described base 3 preferably adopts refractory brick to pile up and forms.Refractory brick has high temperature resistant indeformable feature, support inner bag 2 that can be stable.Described separator 7 also preferably adopts refractory brick to pile up and forms.The preferred employing of described inner bag 2 is conducted heat, high temperature resistant, on-deformable aluminium alloy is made.
Further, between the refractory brick that described base 3 adopts, leave gap (not shown).Gap between refractory brick can make high-temperature flue gas pass through, and high-temperature flue gas is fully contacted with the bottom of inner bag 2, improves the efficiency of heat exchange.
The utility model, by being provided with in exhaust gases passes along the spiralling separator 7 of inner bag 2 outer wall, makes exhaust gases passes 6 form spiralling passage by separator 7.After high-temperature flue gas is entered by air inlet pipe 4, along spiralling channel flow and arrive escape pipe 5 and discharge.This process has increased the circulation path of high-temperature flue gas in exhaust gases passes 6, realizes the sufficient heat exchange of high-temperature flue gas and inner bag 2, effectively improves the heat-exchange capacity of this heat-exchanger rig.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
