Abstract
The utility model relates to a heat pipe type air-air heater which is formed by that a plurality of heat pipes are assembled in a shell, wherein one end of each of the heat pipes is a heat radiating end, the other end is a heat absorbing end; the heat radiating end and the heat absorbing end are separately arranged in an ambient air passage and a flue gas passage, and an isolation layer is arranged between the two passages. The device can make full use of the characteristics of the heat pipes to recover the residual heat in a gas flue for heating the ambient air into the high-temperature air, can effectively recover the residual heat in the gas flue, can effectively save the energy, and can effectively protect the environment. The utility model has the advantages of simple structure, little land occupation, high heat exchanging efficiency, no energy consumption and no environment pollution.
Description
One, technical field
The utility model relates to a kind of heat pipe-type gas-gas heater.
Two, background technology
Heat pipe is one of the most effective heat transfer element, and it can need not additionaling power by very little sectional area transmission with a large amount of heats.Its operation principle is that a pipe is evacuated, charges into working media, one end of pipe is that evaporator section also is a bringing-up section, the other end is that condensation segment also is a cooling section, when an end is heated the liquid medium carburation by evaporation, heat is passed to the other end, emit heat and condense into liquid, liquid flows back to evaporator section again, so circulation.Though utilize the device of heat pipe with the waste heat recovery in the flue and have at present, complex structure, life-span weak point, thereby maintenance difficult often cause the equipment downtime maintenance, surpass to use under 500 ℃ the operating mode in the cigarette temperature to have many problems.
Three, summary of the invention
The purpose of this utility model provides a kind of heat pipe-type gas-gas heater, the characteristic that this heater can make full use of heat pipe is with the waste heat recovery in the flue and surrounding air is heated into high temperature air sends in the blast furnace, improve furnace temperature, it is simple in structure, effectively reclaim the waste heat in the flue, capable of saving fuel, remarkable in economical benefits need not consumes energy, no bath sound, free from environmental pollution.
The purpose of this utility model is achieved in that this heat pipe-type gas-gas heater, be positioned in the housing by some heat pipe combinations, one end of heat pipe is that heat absorbing end, the other end are radiating end, heat absorbing end is in exhaust gases passes, radiating end is in the surrounding air passage, the surrounding air passage has surrounding air air inlet and surrounding air gas outlet, exhaust gases passes that smoke air inlet and flue gas gas outlet are arranged, empty air inlet of environment and surrounding air gas outlet, exhaust gases passes have smoke air inlet and flue gas gas outlet, between surrounding air passage and the exhaust gases passes separation layer are arranged.
The utility model is to utilize the heat pipe recovery waste heat, its advantage is: because of various accidental causes make a certain thermotube wall in the flue gall or damage and also surrounding air can not sneaked in the exhaust gases passes, heat pipe in the equipment is separate disconnected, thus the normal and continuous operation of the equipment of assurance; Since heat pipe heat exchanging device security, reliable, continuous operation for a long time; Its compact conformation, thereby the occupation of land space is less; The heat exchange efficiency height, so energy-saving effect is remarkable, the rate of return on investment height; Waste heat in its recyclable useless cigarette makes exhaust gas temperature reduce greatly, has protected air ambient preferably, and is also free from environmental pollution.
Four, description of drawings
Fig. 1 is a front view of the present utility model.
Five, the specific embodiment
Among Fig. 1, heat pipe-type gas-gas heater, be positioned in the housing 2 by 1 combination of some heat pipes, one end of heat pipe 1 is that heat absorbing end 3, the other end are radiating end 4, heat absorbing end 3 is in exhaust gases passes 5, radiating end 4 is in passage 6, and surrounding air passage 6 has surrounding air air inlet 7 and surrounding air gas outlet 8, exhaust gases passes 5 that smoke air inlet 10 and flue gas gas outlet 11 are arranged, and between surrounding air passage 6 and the exhaust gases passes 5 separation layer 9 is arranged.
When having a large amount of high-temperature flue gas to pass through in the flue, heat absorbing end 2 by heat pipe 1 is taken out the waste heat of high-temperature flue gas, and the surrounding air in the surrounding air passage 6 is heated into high temperature air, high temperature air 7 is discharged and is admitted to the blast-furnace roasting chamber from the gas outlet, but fuel saving, improves stove hall temperature.
