Abstract

The utility model relates to a novel air hot blast furnace. The utility model has the advantages of high heat efficiency, small unit calorie investment, big heat source selection, convenient maintenance, and no easy damage after the shutdown of the utility model. Components of the utility model comprises a heat source flowing path and a hot blast flowing path. A heat absorbing end and a cooling end are respectively formed in two apart cavity bodies. The two cavity bodies are distributed nearly, and heat pipes or metal pips which are respectively positioned on the two cavity bodies can be in a vertical structure or a horizontal structure. The heating load of the utility model can be adjusted, and the length of the casing and the height of the utility model are limberly designed. The utility model is suitable for heating in life and industry.

Description

Air hot-blast furnace

The utility model belongs to technical field of heat exchange, and specifically a kind of is the air heat-exchanging device of Heat Conduction Material by metal or superconductive medium.

General water or other liquid of adopting of family's heating is made thermal medium, utilizes the pipeline circulation to realize heat supply, and this heat-supplying mode thermal efficiency is lower, and needs the pipeline investment, and investment cost is higher in domestic heating.

The utility model purpose is to disclose a kind of Air hot-blast furnace, has the heat exchange efficiency height, and equipment investment is little, the advantage that the thermal source range of choice is big.

The utility model is made up of a thermal source runner and hot blast runner, it is characterized in that thermal source runner and hot blast runner are that levels is arranged or inside and outside sleeve type is arranged, between two runners, erect many heat pipes or fume pipe are arranged, one end or the fume pipe metallic object of heat pipe absorb heat in the thermal source runner, and the other end or flue gas tube wall another side dispel the heat in the hot blast runner.Heat pipe outer wall in the hot blast runner is covered with the heat radiation wing.

Below with reference to embodiment description of drawings ins and outs.

Fig. 7 is the main cutaway view of the utility model embodiment 3.

Fig. 8 is the cutaway view of the utility model embodiment 4.

Fig. 1 is a vertical vacuum heat pipe air hot-blast stove, lower bottom part is placed with thermal source 4, between thermal source runner 1 and the hot blast runner 2 dividing plate 5 is arranged, left the cigarette space, a blower fan 7 between heat pipe 3 lower end gain of heat plates 6 and heat pipe, dry from top hot blast runner, blow out hot blast by hot wind outlet 8, deliver to the place that needs heat supply, to the top exhaust opening 9 smoke exhaust pipe 10 is housed from dividing plate 5, the choked flow blade is arranged, to increase the absorption of fume afterheat in the smoke exhaust pipe.

Fig. 4 to Fig. 6 is a horizontal vacuum heat pipe air hot-blast stove, the bottom cavity is formed by central dividing plate and termination portion back flow plate 11 can turn round runner, there is dividing plate 5 on the upper strata with following interlayer, make levels form individual cavity, erect many heat pipes between two chambeies, upper strata hot blast runner can divide several independent runners, and each is converged by the blower fan air outlet of blowing.

Fig. 7 is vertical tubular type air air-heater, the vertical clapboard 12 densely covered multilayers that are arranged in parallel are arranged many airducts 13, housing sidewall is imported and exported, exposed to airduct, by return air plate 14, make group airduct 15 form the hot blast loops, and by the fan air feed, following group airduct is separately by a blower fan air feed with organizing airduct 16 down, the place converges at air outlet, and flue gas is guided to exhaust opening by vertical clapboard.

Fig. 8 is a horizontal pipe air air-heater, flue gas is sucked from one group of smoke pipe by air-introduced machine, its this group smoke pipe air outlet changes two groups of smoke pipes over to through back flow plate, so form reverse-flow type thermal source runner 1, form the hot blast chamber by smoke pipe outer wall place cavity, can be divided into several individual cavity by blower fan air feed separately, converge at the other end.

The utility model is blown at a high speed by blower fan, outwards transmit heat in the hot-air mode, thermal source absorbs heat by heat pipe and smoke pipe,, by the high speed winds that blower fan produces heat is taken away in the cavity of hot blast runner place by heat-conducting medium in the heat pipe or the heat conduction of metal tube own.

The utility model unit's kilocalorie counts that cost is low, and fuel savings is applicable to multiple supplying heat source, and thermal efficiency height does not have dangerously, and the speed that heats is fast, is not afraid of bursting by freezing during the blowing out heat supply, can be used as family, factories and miness etc. little in the heating of big heat supply district.

Claims (1)

1, a kind of Air hot-blast furnace, a thermal source runner (1) and hot blast runner (2) are arranged, it is characterized in that: thermal source runner (1) is that levels is arranged or inside and outside sleeve type is arranged with the hot blast runner, between two runners, erect many heat pipes (3) or fume pipe are arranged, one end of heat pipe or fume pipe metallic object absorb heat in thermal source runner (1), and the other end or flue gas tube wall another side dispel the heat in the hot blast runner.
