Abstract
The utility model relates to a novel horizontal hot-air boiler, which comprises a heat exchange tube (7) transversely arranged between a front smoke box (1) and a back smoke box (9), wherein the back smoke box (9) via a smoke ascending branch below is connected with a combustion chamber (11), and the smoke inlet of a first return heat exchange tube is mounted with a ceramic tube (8) inside. The utility model arranges a ceramic tube in the first return heat exchange tube, to reduce local high-temperature load of the heat exchange tube, to protect the heat exchange tube, thereby improving the service life of the heat exchange tube from 3-5 years to 8-10 years. And the utility model arranges deflection bricks to distribute the smoke in the heat exchange tube uniformly, to improve the temperature of the hot-air outlet of 20 DEG C around, thereby improving heat exchange efficiency of the hot-air furnace.
Description
Technical field
The utility model relates to a kind of horizontal hot air boiler.
Background technology
Mainly there is following shortcoming in existing hot air boiler; the first, heat exchanger tube generally adopts the Q235 seamless steel pipe; but take safeguard measure owing to do not exchange heat pipe, under the effect of expanding with heat and contract with cold, high-temperature flue gas exchange heat pipe corrodes more serious; the first backhaul heat exchanger tube smoke inlet end particularly; environment temperature reaches 800--900 ℃, causes heat exchanger tube shorter service life, has not only increased the boiler operation cost; and increased the work load that heat exchanger tube is changed, influenced production efficiency.The second, the flue gas ascent stage between the combustion chamber and the first backhaul heat exchanger tube smoke inlet end, smoke distribution is even inadequately, causes the hot-blast outlet temperature on the low side, influences the heat exchange efficiency of hot-blast stove.
Utility model content technical problem to be solved in the utility model is, a kind of novel horizontal hot air boiler is provided, first, prolong heat exchanger tube service life, second, improve the heat exchanger effectiveness of hot air boiler by taking safeguard measure.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme.
A kind of novel horizontal hot air boiler comprises laterally being installed in front smoke box and the back heat exchanger tube between the smoke box, and back smoke box below is characterized in that by-flue gas ascent stage connection combustion chamber: the first backhaul heat exchanger tube go into flue gas end inside, earthenware is installed.
The length of earthenware is the 15%--20% of single heat exchange tube length overall.
Be adhesively fixed by high-temperature-resistant adhesive between the earthenware and the first backhaul heat exchanger tube.
Back smoke box connects the flue gas ascent stage by dividing firebrick; Dividing firebrick is the refractory brick that offers some longitudinal holes.
Good effect of the present utility model is: (1), by in the first backhaul heat exchanger tube, earthenware being installed, having alleviated heat exchanger tube localized hyperthermia load, the exchange heat pipe plays a protective role, and makes heat exchanger tube bring up to 8--10 by original 3--5 service life.(2), make the smoke distribution that enters heat exchanger tube more even, the hot-blast outlet temperature has been improved about 20 ℃, the heat exchange efficiency of hot-blast stove is improved by install dividing a firebrick.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the shell of this hot air boiler is an insulation shell 16, surrounds combustion chamber 11 by refractory concrete 13, is provided with slag removing chamber 12 and falling dust room 14 below combustion chamber 11, falling dust room's 14 arranged outside shoot doors 15.
Laterally be provided with heat exchanger tube 7 in the heat exchange zone above combustion chamber 11, one end of heat exchanger tube 7 is the front smoke boxs 1 that have outlet flue 2, the other end is the back smoke box 9 that connects the flue gas ascent stage by minute firebrick 10, wherein, divides firebrick 10 for offering the refractory brick of some longitudinal holes.Above heat exchanger tube 7, be provided with air inlet 4 and air outlet 6.In heat exchange zone, also be vertically arranged with median septum 5.The left end of heat exchanger tube 7 promptly probes into front smoke box 1 end and is fixed on front smoke box 1 one sides by graphite-seal ring 3.The right-hand member of heat exchanger tube 7 promptly probes into back smoke box 9 ends and is fixed on back smoke box 9 one sides by graphite-seal ring 3.
At the right-hand member of the first backhaul heat exchanger tube, to float earthenware 8 is installed, the length of this earthenware 8 is the 15%--20% of single heat exchange tube length overall.Earthenware 8 is installed in the first backhaul heat exchanger tube inside, is adhesively fixed by high-temperature-resistant adhesive between them.
Burning and flue gas loop have been formed in outlet flue 2, front smoke box 1, heat exchanger tube 7 inside, back smoke box 9 and combustion chamber 11, air outlet 6, air inlet 4, median septum 5 and the heat exchanger tube 7 peripheral common hot-air circuit of forming, combustion chamber 11, falling dust room 14, branch firebrick 10, back smoke box 9, heat exchanger tube 7 and front smoke box 1 etc. are formed heat-exchanging loop.
Claims (4)
1. novel horizontal hot air boiler, comprise the heat exchanger tube (7) that laterally is installed between front smoke box (1) and the back smoke box (9), back smoke box (9) below connects combustion chamber (11) by a flue gas ascent stage, it is characterized in that: the first backhaul heat exchanger tube go into flue gas end inside, earthenware (8) is installed.
2. novel horizontal hot air boiler according to claim 1 is characterized in that: the length of earthenware (8) is the 15%--20% of single heat exchange tube length overall.
