Abstract
The utility model provides a silicon carbide smelting furnace comprising a furnace head, an electrode, furnace walls and a frame. The furnace walls is made by refractory brick masonry and is provided with vent holes therein as well as inlet holes at outside. The refractory bricks are provided with through holes therebetween. The utility model is convenient in brick masonry, due to the regular vent through holes provided between layers after masonry, environment pollution can be reduced, and energy can be saved as well.
Description
The utility model relates to sic smelting furnace.
In the existing technology, the furnace wall of sic smelting furnace is by refractory brick being built in layer, layer and the layer between with the mortar pad every reserving steam vent, the CO gas that generates when this furnace wall can only make reaction is in the external firing of stove, thereby efficiency of combustion is low, for the designer of this this utility model once designed " a kind of furnace wall of sic smelting furnace " and obtained patent right (ZL97223674).The furnace wall of this sic smelting furnace has well solved the problems referred to above.But above-mentioned furnace wall is owing to be made up of for three layers stove interior wall, stove exterior wall, intermediate layer wall, and steam vent only just can form when build furnace wall, thereby the shortcoming that has lay inconvenience, pore opening to differ.Especially the steam vent in intermediate layer, exact grasp when being difficult in lay.
The purpose of this utility model is convenient, the steam vent sic smelting furnace of the same size of a kind of lay of design.
Scheme of the present utility model is as follows:
This sic smelting furnace comprises burner, electrode, furnace wall and framework, and furnace wall is to be formed by fire-resistant brick system, and the furnace wall the inside is provided with steam vent, and the outside is provided with air admission hole, is provided with through hole in the middle of the refractory brick.
The utility model lay is convenient, and the steam vent size is consistent.Furnace wall is an individual layer, but has the effect in inner furnace wall, outer furnace wall and intermediate layer.The nature that concerns owing to groove between the layer of brick and the layer forms the passage of gas.The furnace wall brick is after furnace wall is built into, and neat exhaust hole between layer and the layer has formed the CO combustion chamber.Reduce environmental pollution, saved energy.
Below in conjunction with drawings and Examples the utility model is illustrated:
Fig. 1 is the structural representation of the utility model furnace wall outside.
Fig. 2 is the structural representation of the utility model furnace wall the inside.
Fig. 3 is the utility model vertical view.
Fig. 4 is the single firebrick structure schematic diagram of the utility model (front view, vertical view, left view).
The single band groove of Fig. 5 the utility model firebrick structure schematic diagram (front view, vertical view, A-A are to generalized section).
As shown in Figure 1, 2, 3, this sic smelting furnace comprises burner 1, electrode 5 and furnace wall 2, and the middle part is a reaction zone 10.Furnace wall 2 is to be formed by fire-resistant brick 3 systems of building, and furnace wall 2 the insides are provided with steam vent 9, and the outside is provided with air admission hole 8, and steam vent 9 is more than air admission hole 8.Whole furnace wall 2 is fixed by the framework 4 that refractory concrete and channel-section steel are composited.As shown in Figure 4, be provided with the vertically full through hole 6 that connects in the middle of the refractory brick 3, after furnace wall 2 systems of building were finished, through hole 6 up/down perforations formed the CO gas combustion chamber.As shown in Figure 5, refractory brick the inside also is provided with laterally half groove 7 that connects, and lucky and through hole 6 forms " L " type passage, is beneficial to discharge CO gas CO is burnt preferably.
