Abstract
The utility model relates to a thermal insulation device for a melting furnace and belongs to the technical field of melting furnaces. The thermal insulation device for the melting furnace comprises a furnace lining and a shell. The shell is arranged outside the furnace lining, a vacuum tube is arranged between the shell and the furnace lining, and space defined by the shell, the furnace lining and the vacuum tube in a surrounding mode is filled with thermal insulation material. The thermal insulation device for the melting furnace has a good thermal insulation effect, heat loss can be effectively decreased, energy consumption inside the furnace and flue gas emission are reduced, and pollution to the surroundings is reduced.
Description
Technical field
The utility model relates to a kind of furnace insulation device, relates in particular to a kind of attemperator of melting furnace.
Background technology
The Insulation of traditional metal melting furnace is to lay insulation material in the outside of furnace lining, as asbestos, expanded polyethylene foam etc., although can reach certain insulation requirement, but heat insulation effect is not fine, the thermal loss of body of heater outside is large, very high for maintaining the energy that in stove, temperature need to consume, the flue gas producing is large, pollutes surrounding enviroment.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of melting furnace attemperator is provided, and high insulating effect, the loss of body of heater external heat is little, and energy consumption is low.
Melting furnace attemperator described in the utility model, comprises furnace lining, housing, and furnace lining outside is housing, between housing and furnace lining, vacuum tube is set, fill insulant material in the space that housing, furnace lining, vacuum tube surround into.
Vacuum tube can play good heat-blocking action, improves heat insulation effect, and insulation material is the insulation materials such as nano heat insulating material or rock wool or mineral wool.
Described vacuum tube cross section is square or circular, and vacuum tube is high aluminium material.High-Alumina goods not only can be high temperature resistant, is also good insulation material.Vacuum tube can adopt discarded high alumina vacuum tube, obsolete material can be recycled, economic environmental protection.Vacuum tube can be arranged on the surrounding of furnace roof, furnace bottom and stove, omnibearing heat insulation effect.
Described vacuum tube and the laminating of furnace lining outer surface, two adjacent vacuum tube sides are bonded to each other.
The vertical hoop of described vacuum tube is arranged in furnace lining side, and vacuum tube is horizontally disposed in furnace lining top and bottom.
Operation principle and process:
The transfer mode of heat has three kinds: radiation, convection current and conduction.Heat energy from furnace lining to housing transmittance process, due to adding of High-Alumina vacuum tube, obviously reduce in heat conducting path, owing to being vacuum state in vacuum tube, stopped heat and by convection type, transmitted in vacuum tube, and High-Alumina vacuum tube itself had both stopped that the radiation delivery of heat had reduced the conducting effect of heat.In sum, vacuum tube plays good blocking effect to the transmission of heat.
The beneficial effect that the utility model compared with prior art had is:
By using vacuum tube and fill nano heat insulating material between furnace lining and housing, can play good heat insulation effect to melting furnace, can effectively reduce the loss of heat, reduce energy consumption in stove, reduce fume emission, reduce the pollution to surrounding enviroment; Adopt discarded high alumina vacuum tube, waste wood is recycled, economic environmental protection.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1.
In figure: 1, housing; 2, insulation material; 3, vacuum tube; 4, encapsulant; 5, furnace chamber; 6, furnace lining; 7, bocca; 8, fire door.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, melting furnace comprises furnace lining 6, furnace chamber 5, fire door 8 and bocca 7, fire door 8, bocca 7 is arranged on furnace lining 6 sidepieces, furnace lining 6 inside are furnace chamber 5, furnace lining 6 outsides are housing 1, between housing 1 and furnace lining 6, vacuum tube 3 is set, vacuum tube 3 and furnace lining 6 outer surface laminatings, two adjacent vacuum tube 3 sides are bonded to each other, the vertical hoop of vacuum tube 3 is arranged in furnace lining 6 sides, vacuum tube 3 is horizontally disposed in furnace lining 6 top and bottom, vacuum tube 3 is preferentially selected round tube, housing 1, furnace lining 6, in the space that vacuum tube 3 surrounds into, fill insulant material 2, the tubing that vacuum tube 3 preferred cross-sections are circular high aluminium material, the preferential nano heat insulating material of insulation material 2.Vacuum tube 3 can adopt obsolete material, also can be by vacuumizing in the middle of high aluminum pipe, and the mode that two ends add encapsulant 4 sealings obtains.
Fig. 2 is that vacuum tube 3 is at the arrangement mode of body of heater side.
Heat energy from furnace lining 6 to housing 1 transmittance process, due to adding of High-Alumina vacuum tube 3, obviously reduce in heat conducting path, in managing, it is vacuum state, stopped heat transmits by convection type in vacuum tube 3, and High-Alumina vacuum tube 3 itself had both stopped that the radiation delivery of heat had reduced the conducting effect of heat, between vacuum tube 3 and housing 1, fill nano heat insulating material, make heat insulation effect better.
This melting furnace attemperator has good heat insulation effect, can effectively reduce the loss of heat, reduces energy consumption in stove, reduces fume emission, reduces the pollution to surrounding enviroment; Adopt discarded high alumina vacuum tube, waste wood is recycled, economic environmental protection.
