Description
Technical field
The utility model relates to the improvement technology of filling ball heat accumulating type energy-saving aluminum melting furnace preheated air (or coal gas) structure.
Background technology
Nineteen eighty-two, Britain HotworkDevelopment company and BritishStation research institute cooperate, and have developed in the world First filling ball regenerative oven.At that time, the title of this development plan was: Ceramic Balls heat-accumulating burner (RegenerativeCeramieBurner) combustion system of glass-melting furnace.After that stove appearance, some industrially developed country have adopted this technology in the world, and application expands the fusing of aluminium, heating, forging and the annealing of steel to soon from the fusing of glass, and the heat treatment of steel band, steel pipe and foundry goods etc.Filling ball regenerator technology is fuel savings, reduction cost and raising output to greatest extent, has also reduced the discharge capacity of pollutant simultaneously, is a kind of extremely promising new technology.China starts late in this respect, only has so far several stoves to adopt this technology.
The filling ball regenerative oven utilizes the heating by the exhaust gases air (or coal gas) of burner hearth, and prior art adopts following two kinds of methods: the one, and regenerator (Regenerator), the 2nd, heat exchanger (Reeuperator).The tradition regenerator comprises the shell of regenerator and inner checker work grillage, all uses refractory material laying.Waste gas makes it temperature by checker work grillage and rises; After the commutation, air is by checker work grillage, and air is preheated, and checker work grillage is lowered the temperature.A stove has a pair of regenerator at least, and one is used for the heating brick grid, and one is used for warm-up combustion-supporting air.Heat exchanger, for example tubular exchanger is formed by many steel-pipe weldings.Heat exchange is carried out by tube wall in waste gas and the air pipe both sides of flowing through simultaneously, and waste gas is cooled, and air is preheated.
Preheating structure preheated air (or coal gas) effect of existing filling ball regenerative oven is bad, and warm consumes the heat in the stove, and the pre-thermal efficiency is low.
Summary of the invention
The utility model provides a kind of filling ball heat accumulating type energy-saving aluminum melting furnace, it is bad that the utility model has solved preheating structure preheated air (or coal gas) effect that has the filling ball regenerative oven now, warm consumes the heat in the stove, the inefficient problem of preheating.
For addressing the above problem, the utility model adopts following technical scheme: the filling ball heat accumulating type energy-saving aluminum melting furnace, comprise filling ball regenerative oven 1, be provided with left combustion chamber 2 and right combustion chamber 3 at filling ball regenerative oven about 1, in left combustion chamber 2 and the right combustion chamber 3 burner is installed; Also comprise left regenerator 4, right regenerator 5, reversing arrangement 6, induced-draft fan 7 and air blast 8; Below left combustion chamber 2 and right combustion chamber 3, be respectively arranged with right combustion chamber 3 and left regenerator 4; Reversing arrangement 6 connects left regenerator 4, right regenerator 5, induced-draft fan 7 and air blast 8 by pipeline.
The utility model filling ball heat storing type energy-saving smelting furnace is suitable to close in the processing of Hu aluminium its advantage: utilize the heating by the exhaust gases air (or coal gas) of burning, and effective, do not consume the heat in the stove, the pre-thermal efficiency is high.

Fig. 1 is the utility model structural representation.
Symbol description among the figure: filling ball regenerative oven 1, left combustion chamber 2, right regenerator 3, left regenerator 4, right regenerator 5, reversing arrangement 6, induced-draft fan 7, air blast 8.
The specific embodiment
The below is described in detail the utility model with best embodiment.
As shown in Figure 1, the filling ball heat accumulating type energy-saving aluminum melting furnace comprises filling ball regenerative oven 1, is provided with left combustion chamber 2 and right combustion chamber 3 at filling ball regenerative oven about 1, in left combustion chamber 2 and the right combustion chamber 3 burner is installed; Also comprise left regenerator 4, right regenerator 5, reversing arrangement 6, induced-draft fan 7 and air blast 8; Below left combustion chamber 2 and right combustion chamber 3, be respectively arranged with right combustion chamber 3 and left regenerator 4; Reversing arrangement 6 connects left regenerator 4, right regenerator 5, induced-draft fan 7 and air blast 8 by pipeline.
The utility model is installed a pair of regenerator and a pair of burner at least in its both sides.Each burner can only be equipped with a regenerator (warm-up combustion-supporting air), also can be equipped with two regenerator (simultaneously preheated air and coal gas)." burner " has two effects, and the one, organize fuel combustion, the 2nd, discharging burner hearth waste gas.Concerning the general industry stove, both effects are contradiction, and with regard to the filling ball regenerative oven, both can take into account.Because during the high temperature more than combustion air is preheating to ignition temperature, the burning of coal gas seems very easy, so the filling ball heat-accumulating burner can be designed to two coal gas and air passage port simply.They mix in stove and burn, and discharge combustion product passway over there.After each commutation, the effect of these two passwaies is exchanged once.Because the burner hearth waste gas streams is very low through the discharge temperature of regenerator, so get final product with straight carbon steel making flue and reversing arrangement.Reversing arrangement can be two five-way valves.Every stove is installed one group of (preheated air) five-way valve at least.Two stomidiums of five-way valve are waste gas outlet, and with induced-draft fan, interstitial hole is the entrance of combustion air, is communicated with air blast.Remaining two hole is communicated with two regenerator respectively, and the conversion of reversing arrangement is with compressed air or driven by power.
It should be noted that at last: obviously, above-described embodiment only is for the utility model example clearly is described, and is not the restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And the apparent variation of being amplified out thus or change still are among the protection domain of the present utility model.
