Abstract

The utility model discloses a silicon charring smelting furnace with a composite furnace wall, which comprises a furnace head 1, a reaction zone 7, electrodes 5 and a base furnace wall 8, wherein the outer part of the base furnace wall 8 is provided with a movable and detachable thermal-insulating furnace wall 2, a burning chamber 6 with larger space for carbon monoxide is arranged between the thermal-insulating furnace wall 2 and the base furnace wall 8, and air inlets 3 are arranged between the layers of the thermal-insulating furnace wall 2. The utility model has the advantages of light furnace wall weight, less investment, high utilizing rate of burning, less environmental pollution and energy saving.

Description

A kind of carborundum smelting furnace that has compound furnace wall

The utility model relates to a kind of carborundum smelting furnace that has compound furnace wall.

In the existing technology, the furnace wall of the carborundum smelting furnace that has in layer is built into by refractory brick, leaves steam vent between layer and layer, and the shortcoming of this furnace wall is that combustion utilization efficiency is low.Also having a kind of is the network structure that the mutual snap-in of moulding refractory brick constitutes, and three layers is an integral body.Though the furnace wall of this carborundum smelting furnace can solve the low problem of combustion rate well, the weight of furnace wall is heavier.Especially a transformer will match with five smelting furnaces in the smelting process of carborundum, and the furnace wall gross investment that amounts to five smelting furnaces is just bigger.

The purpose of this utility model is that design a kind ofly can improve CO gas combustion rate, can make again that overall furnace wall is in light weight, a kind of carborundum smelting furnace that has compound furnace wall of small investment.

The utility model scheme is as follows: comprise in the smelting furnace of burner 1, reaction zone 7, electrode 5, basic furnace wall 8 in the outside of basic furnace wall 8, an insulation furnace wall 2 of being made by light-weight insulating brick being arranged.Between insulation furnace wall 2 and basic furnace wall 8 space being arranged is CO gas combustion chamber 6, between the layer of insulation furnace wall 2 and the layer air admission hole 3 is arranged.Between the layer of base furnace wall 8 and the layer steam vent 9 is arranged.Insulation furnace wall 2 is fixed into one by the framework made from channel-section steel 4, and insulation furnace wall 2 also can be movable removable.

The utility model is in light weight, since the CO gas combustion chamber that has living space bigger, the combustion utilization efficiency height.The insulation furnace wall can dismounting, therefore can match with five carborundum smelting furnaces once cover insulation furnace wall.Promptly when first carborundum smelting furnace work, the movable removable insulation furnace wall 2 and the basic furnace wall of first smelting furnace are assembled into the complete smelting furnace wall of a cover.After having smelted, insulation furnace wall 2 can be assembled into the complete smelting furnace wall of a cover again with the basic furnace wall of another smelting furnace.So circulation has reduced the investment of furnace wall, has alleviated the weight of furnace wall.Owing to the existence of the space CO gas combustion chamber between two furnace walls, CO gas can fully burn, and has not only reduced environmental pollution, has also saved energy.

Below in conjunction with accompanying drawing the utility model is illustrated:

Fig. 1-Fig. 3 is the utility model structure chart.

Fig. 1 is the utility model front view;

Fig. 2 is the utility model vertical view;

Fig. 3 is that the A-A of Fig. 2 is to view.

As shown in the figure, have air admission hole 3, framework 4 will be incubateds furnace wall 2 respectively between burner 1, insulation furnace wall 2, electrode 5,2 layers of insulated walls and the layer and basic furnace wall 8 is fixing in aggregates, basic furnace wall 8 layer and layer between steam vent 9 is arranged.Between insulation furnace wall 2 and the basic furnace wall 8 a bigger space being arranged is CO gas combustion chamber 6.In the middle of the stove is reaction zone 6.Insulation furnace wall 2 is the removable of activity.Be assembled into the complete furnace wall of a cover with the basic furnace wall 8 of five carborundum smelting furnaces.
