Description
Technical Field
The utility model relates to an electric melting furnace water jacket, concretely relates to doublestage water jacket for electric melting furnace belongs to glass electric melting furnace technical field.
Background
Glass kilns are classified according to the nature of the energy used and can be classified into flame kilns, electric melting-assistant kilns and all-electric melting kilns.
The electric boosting and all-electric melting furnaces basically use molybdenum electrodes as power-up devices, and most furnaces are powered up by cylindrical molybdenum electrodes. Because the molybdenum electrode has the characteristic of high-temperature oxidation in the air, the molybdenum electrode of the electric heating kiln needs a water jacket to protect the molybdenum electrode.
In the use engineering of the water jacket, the upper part of the water jacket head is contacted with molten glass, the internal circulating water pipe of the water jacket adds water into the water jacket body to cool the upper part of the water jacket head, keeps the temperature of the upper part of the water jacket head not high, and closes the gap between the molybdenum electrode and the inner pipe of the water jacket in a cooling state, thereby protecting the molybdenum electrode at the lower part of the water jacket head from being oxidized; meanwhile, the water can be introduced into the water jacket to cool the electrode bricks around the water jacket, so that the service life of the refractory material is prolonged.
However, in the long-time use process, the electrode bricks are gradually eroded, when the kiln is used for about 3 years, the electrode bricks are eroded to a certain degree, the part of the electrode bricks close to the center of the kiln is completely eroded, the water jacket head is basically exposed in glass liquid, the protection of refractory materials is lost, the temperature of the water jacket head is increased, the water jacket head is continuously flushed due to the fact that the glass liquid flows from top to bottom, the water jacket head is damaged, particularly, the water jacket stops water during the operation process, the temperature of the water jacket head is higher, the erosion of the glass liquid to the water jacket head is more serious, and finally the inner side of the water jacket head leaks water and the water jacket is damaged.
After the water jacket is damaged, the water jacket cooling circulating water pressure cannot be opened to normal pressure, if the normal pressure is kept, water can enter the glass liquid inside the kiln to form a bubbling phenomenon, so that part of unmelted batch enters the lower part of the kiln, the quality of the glass liquid is poor, and the quality of a product is seriously influenced, so that the pressure can be reduced only, the glass liquid can enter the cavity of the water jacket, the cooling part of the water jacket moves downwards, and the erosion of the glass liquid to an electrode brick and the head of the water jacket is more serious; simultaneously because the entering cooling return water pipeline of glass liquid blocks up, for solving the cooling return water pipe and blockking up, closed water jacket becomes open water jacket, adds the water yield and increases, and a large amount of heats can be taken away to water, makes the unit energy consumption of glass liquid increase, and according to statistical data analysis, the water jacket is normal and melts the energy consumption ratio of unit glass liquid when the water jacket damages and is about 1: 1.3.
all current water jackets are single-stage water jackets, and the water jackets cannot be replaced after being damaged, and only a large amount of water can be cooled outside the water jackets, but the effect is poor, the energy consumption is increased, the safety risk of the kiln is increased, and the service life of the kiln is shortened.
