In prior art, new wind and waste gas carry out mixed heat transfer, have caused the oxygen content deficiency of the new wind that enters combustion chamber, cause burning insufficient.In the utility model, air intake is taken over and is connected with air intake vent through Heat Room, is guaranteeing the heating effect of new wind in Heat Room, the oxygen content that has also guaranteed to enter burning indoor fresh air simultaneously.
These features of the present utility model and advantage will be below the specific embodiment, accompanying drawing in detailed exposure.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further:
Fig. 1 is the front view of a kind of heating furnace waste-heat recovery device of the utility model;
Fig. 2 is the side view of a kind of heating furnace waste-heat recovery device of the utility model.
The specific embodiment
The utility model provides a kind of heating furnace waste-heat recovery device, comprise heating furnace, described heating furnace is provided with combustion chamber and blast pipe, described combustion chamber is provided with combustion gas adapter, air intake takes over and waste gas is taken over, described waste gas is taken over and is connected with blast pipe, described waste gas is taken between described blast pipe and is provided with Heat Room, and described Heat Room is provided with air intake vent, and described air intake is taken over and is connected with described air intake vent through Heat Room.By taking between blast pipe a Heat Room be set at waste gas, heat in the waste gas that can make to discharge carries out heat exchange with the new wind of coming in from air intake vent in Heat Room, new wind is preheated, not only reduce the temperature of the waste gas of discharging, and novel wind energy after preheating is enough and combustion gas mixing after, also combustion gas is preheated, finally make combustion efficiency better, burn more abundant.In prior art, new wind and waste gas carry out mixed heat transfer, have caused the oxygen content deficiency of the new wind that enters combustion chamber, cause burning insufficient.In the utility model, air intake is taken over and is connected with air intake vent through Heat Room, is guaranteeing the heating effect of new wind in Heat Room, the oxygen content that has also guaranteed to enter burning indoor fresh air simultaneously.
Accompanying drawing below in conjunction with the utility model embodiment is explained and illustrated the technical scheme of the utility model embodiment, but following embodiment is only preferred embodiment of the present utility model, not all.Based on the embodiment in embodiment, those skilled in the art are other embodiment that obtains under the prerequisite of not making creative work, all belong to protection domain of the present utility model.
Shown in seeing figures.1.and.2, a kind of heating furnace waste-heat recovery device, comprise heating furnace, the blast pipe 4 that described heating furnace is provided with combustion chamber 1 and vertically arranges, the below of blast pipe 4 is located in combustion chamber 1, described combustion chamber 1 is provided with combustion gas adapter, air intake adapter 2 and waste gas and takes over 9, described waste gas is taken over 9 and is connected with blast pipe 4, between described waste gas adapter 9 and described blast pipe 4, be provided with Heat Room 3, be provided with air intake vent 7 at the top of Heat Room 3, described air intake is taken over 2 and is connected with described air intake vent 7 through Heat Room 3.A dust cover is installed in air intake vent 7 positions, prevents that dust or foreign material etc. from entering air intake and taking in 2, causes combustion chamber 1 to burn insufficient; As simple replacement, in air intake vent 7 positions, an anti-dust filter mesh is installed, for blocks dust or foreign material; Or, at the aperture position of dust cover, anti-dust filter mesh is installed.When concrete enforcement, between waste gas adapter 9 and Heat Room 3, be communicated with by instlated tubular.Meanwhile, in order to guarantee the heat insulation effect of the new wind after heat exchange, take over outer wall parcel one layer of heat preservation material at new wind, as: asbestos, heat insulation sponge etc.
In the present embodiment, further improved, in described Heat Room 3, be provided with heat pipe, take full advantage of the Rapid Thermal hereditary property of heat-conduction principle and phase change medium, see through heat pipe the heat of thermal objects is delivered to rapidly outside thermal source, its capacity of heat transmission exceedes the capacity of heat transmission of any known metal.Described heat pipe comprises heat absorbing end and release end of heat, and described heat absorbing end is taken over 9 with described waste gas and contacted, and described release end of heat is taken over 2 with described air intake and contacted.
