Abstract
The utility model relates to a heat storage type heat-pipe heat exchanger, comprising a flue gas inlet, a flue gas channel, a heat pipe group, a flue gas outlet, a circulating pipeline and a steam coalescer, wherein the top of the flue gas channel is provided with the flue gas inlet, and the bottom of the flue gas channel is provided with the flue gas outlet; the flue gas channel is internally provided with the heat pipe group which is connected with the steam coalescer by the circulating pipeline; and the steam coalescer is arranged at the top position of the outer side of the flue gas channel. The heat storage type heat-pipe heat exchanger further comprises a heat storage body which is arranged at the upper end of the heat pipe group in the flue gas channel. In the heat storage type heat-pipe heat exchanger, the structure is simple and reasonable, the heat storage body is added, and the damage of the heat pipe group due to temperature fluctuation of flue gas is avoided; due to heat absorbing function of the heat storage body, the working temperature of a heat storage type heat-pipe steam generator can be increased to be 1200 DEG C, and is 300 DEG C higher than the common heat-pipe heat exchanger, a waste heat recovery system is simple, and other temperature-reducing equipment is not needed.
Description
Technical field
The utility model relates to a kind of heat exchanger, relates in particular to a kind of heat-accumulation type hot heat exchange of heat pipe that can reclaim heat.
Background technology
Metallurgy industry adopts the general heat pipe steam generator to reclaim smoke discharging heat in the electric furnace arrangement for producing steel, produces steam.In a smelting cycle, interior smoke discharging temperature fluctuation is very big, is increased to 1200 ℃ from 120 ℃ usually, and then reduces to 120 ℃.The general heat pipe steam generator can not adapt to above operating mode fully, mainly has the following disadvantages:
1, general heat pipe steam generator operating temperature is not more than 900 ℃.In other words, adopt the general heat pipe steam generator can not reclaim flue gas heat fully.
2, residual neat recovering system complexity must adopt other cooling systems that flue-gas temperature is reduced to below 900 ℃.
3, alternately changing of flue-gas temperature causes heat pipe steam generator pressure parts intensity to descend, and leaks easily.
Summary of the invention
At above-mentioned shortcoming, the utility model technical issues that need to address provide a kind of heat-accumulation type hot heat exchange of heat pipe.
The technical solution adopted in the utility model is:
The heat-accumulation type hot heat exchange of heat pipe, comprise gas approach, exhaust gases passes, heat pipe pipe group, exhanst gas outlet, circulating line and steam coalescer, the exhaust gases passes top is provided with gas approach, the bottom is provided with exhanst gas outlet, exhaust gases passes inside is provided with heat pipe pipe group, and heat pipe pipe group is connected with the steam coalescer by circulating line, and the steam coalescer is located at exhaust gases passes outside top position, also comprise heat storage, heat storage is arranged at the inner heat pipe pipe of exhaust gases passes group upper end.
Heat storage by at least 2 groups, at least 2 row, at least 2 row tubuloses or solid bar by being arranged in a combination.
The utility model has the advantages that: simple and reasonable, increase heat storage, avoid heat pipe pipe group to damage because of the flue-gas temperature fluctuation produces, because the heat-absorbing action of heat storage, the operating temperature of heat accumulation type heat pipe steam generator can be increased to 1200 ℃, higher 300 ℃ than general heat pipe heat exchanger, and residual neat recovering system is simple, does not need other cooling systems.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Wherein: 1, gas approach, 2, exhaust gases passes, 3, heat storage, 4, heat pipe pipe group, 5, exhanst gas outlet, 6, circulating line, 7, the steam coalescer.
The specific embodiment
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.
With reference to shown in Figure 1, the utility model heat-accumulation type hot heat exchange of heat pipe, comprise gas approach 1, exhaust gases passes 2, heat pipe pipe group 4, exhanst gas outlet 5, circulating line 6, steam coalescer 7 and heat storage 3, exhaust gases passes 2 tops are provided with gas approach 1, the bottom is provided with exhanst gas outlet 5, exhaust gases passes 2 inside are provided with heat pipe pipe group 4 and heat storage 3, heat storage 3 is arranged at heat pipe pipe group 4 upper ends, heat pipe pipe group 4 is connected with steam coalescer 7 by circulating line 6, and steam coalescer 7 is located at exhaust gases passes 2 outside top positions.
Below the course of work of the present utility model is described further:
During work, high-temperature flue gas enters exhaust gases passes 2 from gas approach 1, flows through heat storage 3 and heat pipe pipe group 4 successively, emits heat, and temperature reduces, and discharges from exhanst gas outlet 5 at last.When flue-gas temperature is higher than 600 ℃, heat storage 3 is from the smoke absorption heat, when flue-gas temperature is lower than 600 ℃, heat storage 5 is emitted heat to flue gas, keeps flue-gas temperature stable, avoids heat pipe pipe group to damage because of the flue-gas temperature fluctuation produces, in addition, because the heat-absorbing action of heat storage, the operating temperature of heat accumulation type heat pipe steam generator can be increased to 1200 ℃, and is higher 300 ℃ than general heat pipe heat exchanger.Heat pipe pipe group 4 absorbs heat always from flue gas, saturation water follows endless tube road 6 and enters heat pipe pipe group 4 in the steam collector 7, absorb heat, form steam water interface, steam water interface is tried hard to recommend the moving steam collector 7 of getting back to again down in Natural Circulation, after the carbonated drink separation, forming steam supplies outward, so simple recovery waste heat does not need other cooling systems, more environmental protection.
