Abstract
The utility model relates to an energy-saving smelting furnace which comprises a furnace body, a hearth, a combustion chamber and a combustion engine. A waste gas exhaust port is formed in the upper end of the furnace body, a heating calancria is arranged on the waste gas exhaust port, one end of the heating calancria is connected with an air blower arranged outside the furnace body through an input air pipe, and the other end of the heating calancria is connected with the combustion engine through an output air pipe. According to the energy-saving smelting furnace, high temperature waste heat of waste gas exhausted out of the furnace is utilized to preheat combustion air led into the combustion engine to enable the temperature of the combustion air to be increased to about 300 DEG C, so that on one hand, combustion velocity of a fuel in the furnace can be accelerated to improve combustion efficiency, on the other hand, the energy utilization rate is also greatly improved, and the greatly advocated energy saving requirement in factory production is met.
Description
Technical field:
The utility model relates to a kind of smelting equipment, particularly a kind of smelting furnace through reducing energy consumption.
Background technology:
The major function of smelting furnace is to utilize high temperature, high-velocity combustion that solid ingot is molten into liquid equipment.During burning, need to enter combustion air to stove internal combustion power traction is burnt fuel, and current smelting furnace is mainly, by air blast, room air is directly introduced to combustor, therefore the temperature of combustion air is lower, under the weather of sweltering heat in summer, at most also with regard to tens degree, other seasons are lower, thereby cause combustor fuel often to need the long period could realize fully, burn completely, efficiency of combustion is very low, needs to be improved.
Utility model content:
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, and a kind of energy-saving smelting furnace that improves energy utilization rate and efficiency of combustion is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of energy-saving smelting furnace, comprise body of heater, burner hearth, combustion chamber and combustor, described body of heater upper end is provided with a waste discharge gas port, the top of described waste discharge gas port is provided with heating calancria, one end of this heating calancria is connected with the air blast that is arranged on described body of heater outside by input airduct, and the other end is connected with described combustor by output airduct.The top of described heating calancria is provided with exhaust fume collecting hood, and this exhaust fume collecting hood is connected with an exhausting pipeline.Described heating calancria is the design of coiled coil shape.
The beneficial effects of the utility model are: the high-temperature residual heat while utilizing the interior waste gas of stove to discharge carries out preheating to introducing the combustion air of combustor, after preheating, the temperature of combustion air rises to 300 ℃ of left and right, thereby can accelerate on the one hand the burning velocity of stove fuel, improve efficiency of combustion, also greatly improve on the other hand energy utilization rate, met the energy-conservation requirement of advocating energetically in plant produced.
Accompanying drawing explanation:
Fig. 1 is the structural representation of the utility model energy-saving smelting furnace.
The specific embodiment:
As shown in Figure 1, a kind of energy-saving smelting furnace providing according to the utility model, comprise body of heater 1, burner hearth 2, combustion chamber 3 and combustor 4, body of heater 1 upper end is provided with a waste discharge gas port 5, the top of waste discharge gas port 5 is provided with heating calancria 6, one end of heating calancria 6 is connected with the air blast 8 that is arranged on body of heater 1 outside by input airduct 7, and the other end is connected with combustor 4 by output airduct 9.During work, by air blast 8, room air is introduced to heating calancria 6, the high-temp waste gas that utilizes waste discharge gas port 5 to discharge carries out preheating, and it is combustion-supporting that after preheating, air enters combustor 4 again.
The top of heating calancria 6 is provided with exhaust fume collecting hood 10, and this exhaust fume collecting hood 10 is connected with an exhausting pipeline 11, in order to by the waste gas of discharging from waste discharge gas port 5, smog etc. concentrated be discharged to outdoor.Heating calancria 6 is the design of coiled coil shape, and design can make the air that enters combustor 4 obtain abundant preheating like this.
Above-described embodiment is only for illustration of the utility model; and be not limitation of the utility model; the those of ordinary skill in relevant technologies field; in the situation that not departing from spirit and scope of the present utility model; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
Claims (3)
