Description

Energy saving and environment friendly combustion gas crucible furnace

One, technical field

The utility model relates to a kind of industrial crucible furnace, especially a kind of combustion gas crucible furnace that utilizes the fuel gas buring heating.

Two, background technology

The industrial crucible furnace that uses in that sell in the market and the factory, all be to adopt with coke, diesel oil or gas burner system crucible furnace as the energy, the large quantity of exhaust gas that produces during its burning directly is discharged in the atmosphere, environment has been caused great pollution, be detrimental to health, and have a large amount of waste heats in the waste gas, thermal loss is big, utilization rate is low, and the thermal efficiency of crucible furnace is low.

Three, the content of utility model

The purpose of this utility model is intended to overcome the deficiency of above-mentioned prior art, and provides a kind of thermal efficiency high energy saving and environment friendly combustion gas crucible furnace.

For achieving the above object, the utility model is achieved in that a kind of energy saving and environment friendly combustion gas crucible furnace, mainly comprise the body of heater shell, air blast, body of heater and be positioned at its burner hearth, place the crucible of burner hearth top, be loaded on the gas burner of burner hearth bottom, body of heater is having a fire hole that stretches out the body of heater shell near the bottom of burner hearth, the top body of heater of burner hearth is provided with flue, its special character is, between body of heater shell and body of heater, a waste heat apotheca that is communicated with flue is arranged, in the waste heat apotheca air heat exchanger is housed, the upper end of air heat exchanger is connected with air delivery pipe, the bottom is connected to the hot air delivery pipe that links to each other with gas burner, air blast is connected with the other end of air delivery pipe, hot air delivery pipe is connected with the fiery gas pipeline of the master of gas burner, also is provided with little kindling material combustion head in the gas burner and is attached thereto the little kindling material gas pipeline that connects.

The utility model compared with the prior art because the waste gas that has a large amount of waste heats is discharged in the waste heat apotheca, by air heat exchanger with air heat, hot-air and combustion gas mixing, not only improved efficiency of combustion, and saved the energy, fuel gas buring is abundant, the fume emission that produces is in atmosphere, environmentally safe, environmental protection, and thermal efficiency height, improved the operating efficiency of crucible furnace greatly, economical and practical.

Four, description of drawings

Fig. 1 is a structural representation of the present utility model.

Five, the specific embodiment

As shown in Figure 1, energy saving and environment friendly crucible furnace described in the utility model mainly is by body of heater shell 12, air blast 1, body of heater 10 and be positioned at its burner hearth 20, place the crucible 13 of burner hearth top, be loaded on that the gas burner 5 of burner hearth bottom constitutes, be filled with fire-resistant composite soil 8 in the space of the bottom of burner hearth 20 and body of heater 10, body of heater 10 is having a fire hole 9 that stretches out body of heater shell 12 near the bottom of burner hearth 20, on the body of heater of the top of burner hearth 20, have flue 14, the top of body of heater shell is provided with chimney 17 and reflection covers 16, transferring of radiation lid is waste heat district 15, in the bottom of burner hearth, the both sides of gas burner respectively have a pressure relief vent 6; Between body of heater shell 12 and body of heater 10, a waste heat apotheca 18 that is communicated with flue 14 is arranged, air heat exchanger 3 is housed in the waste heat apotheca 18, the upper end of air heat exchanger 3 is connected with air delivery pipe 2, the bottom is connected to the hot air delivery pipe 4 that links to each other with gas burner 5, air blast 1 is connected with the other end of air delivery pipe 2, hot air delivery pipe 4 is connected with the fiery Gas Pipe 19 of the master of gas burner, on the main fiery Gas Pipe 19 switch 7 is housed; Be provided with little kindling material combustion head 22 in the gas burner 5 and be attached thereto the little kindling material Gas Pipe 21 that connects; Between body of heater 10 and the body of heater shell 12, between body of heater 10 and the waste heat apotheca 18, all be provided with heat insulation foam 11 between waste heat apotheca 18 and the body of heater shell 12.

After the combustion gas process blowing type gas burner combustion, produce a large amount of thermal energy in the burner hearth, be used for raw material in the heating crucible, along with constantly flowing of hot-fluid, thermal current is carrying partial heat energy and is being discharged in the waste heat apotheca, because heat insulation foam is all arranged around the burner hearth, still keep high temperature so flow into the waste heat of waste heat storage type, come not only but also further keep the interior high temperature of burner hearth simultaneously, waste heat in the waste heat apotheca by air heat exchanger with the air preheat that air delivery pipe transports, reach after the uniform temperature again by hot air delivery pipe in hot-air is transported to gas burner with combustion gas mixing after burning again.

During use, light little kindling material combustion head earlier, open air blast then, air enters air heat exchanger through air delivery pipe, when air preheat after uniform temperature, enter hot air delivery pipe, open the switch on main or the gas pipeline this moment, combustion gas enters in the pipeline with after hot-air mixes, again by gas burner, meanwhile, produce in a large amount of heat energy radiation crucibles, in the burner hearth with the material in the fusion crucible, the part preheating enters the waste heat apotheca by flue, constantly send heat energy to air heat exchanger,, save the energy in order to preheated air; Carry the flue gas of a small amount of hot gas and discharge by chimney, the flue gas of discharge covers at the raw material that will waste heat wherein be used in the preheating waste heat district through reflection, rationally utilizes energy savings.
