Description

A New Type of Glass Furnace

technical field

The utility model relates to a glass furnace, in particular to a wall structure of a novel glass furnace regenerator.

Background technique

At present, there are mainly two types of conventional glass furnaces, one is the glass furnace using natural gas, as shown in Figure 1, this glass furnace using natural gas includes a left air regenerator 11 and a right air regenerator 21 Two air regenerators, a middle partition wall 2 is arranged between the left air regenerator 11 and the right air regenerator 21, and surrounding walls 5 are arranged around the air regenerator; the other is a glass that utilizes gas Furnace, as shown in Figure 2, this kind of glass kiln utilizing gas not only includes two air regenerators, left air regenerator 11 and right air regenerator 21, but also includes left gas regenerator 12 and The right gas regenerator 22 has two gas regenerators, a middle partition wall 2 is arranged between the left air regenerator 11 and the right air regenerator 21, and a middle partition wall 2 is arranged between the left gas regenerator 12 and the right gas regenerator 22. A partition wall 2 is also provided, and a partition wall 2 is also provided between the gas regenerator and the air regenerator. However, we found that during the use of the above two conventional glass furnaces, due to the high local temperature of the middle partition wall 2 or the low softening temperature of the refractory material under load, the actual temperature of the middle partition wall 2 reaches the load of the refractory material. When the softening temperature and creep temperature are reached, the refractory material creeps and shrinks and deforms. Since the middle temperature of the regenerator is the highest, the temperature in the middle of the corresponding middle partition wall 2 is also high, and the creep shrinkage is the most severe, and the temperatures on both sides are relatively high. As a result, the creep shrinkage of the same section of the wall is not the same, and the wall collapses downward and bends. The temperature at the place is not the same, resulting in a different amount of slump, resulting in cracking of the wall, causing fire leakage in the regenerator, especially when the upper and lower materials are different, the amount of slump is even more different, and the wall is cracked The phenomenon is more serious, which affects the normal operation and service life of the kiln; especially in the gas regenerator, once the wall collapses and cracks, the gas will run through the gap to the gas regenerator on the other side for combustion, thus further accelerating the burning of bricks around the crack. The collapse and burning of the body will cause the cracks to grow larger and merge with the lattice body, causing the lattice body to collapse, thus affecting the normal operation and service life of the kiln. The service life of the kiln is terminated, and the surrounding wall 5 around the regenerator has one side directly in contact with the outside world, which can dissipate part of the heat. The corrosion of the wall and the lower seat are not serious. When the middle partition wall 2 can no longer be used, The furnace has to be shut down for maintenance, and the surrounding wall body 5 can continue to be used for several years or even longer, but the partition wall 2 needs to be dismantled around the wall body connected to each other in the maintenance, thereby causing a large amount of waste of manpower and material resources.

Contents of the invention

The technical problem to be solved by the utility model is to provide a new type of glass kiln, which changes the wall structure between the regenerators of the original glass kiln, prolongs the service life of the glass kiln, and reduces the waste of manpower and material resources.

In order to solve the above technical problems, the utility model provides a new type of glass kiln, which includes two air regenerators, a partition wall is arranged between the two air regenerators, and a cooling The channel and the wall connecting brick connect the walls on both sides of the partition wall and the cooling channel into a whole through the wall connecting brick.

The regenerator wall structure of the glass kiln adopts this technical solution. Since the cooling channel and the wall connecting brick are arranged in the middle partition wall, the cooling channel divides the middle partition wall into two parts, and these two parts pass through the wall. The body connecting bricks are connected to form an overall structure, which not only cools down the middle partition wall, but also ensures the stability of the structure.

The channel uses the principle of heat convection to make the cooling channel of the partition wall take away part of the heat through the cooling air, thereby reducing the ambient temperature of the partition wall, making the actual temperature below the softening temperature of the refractory material, avoiding The refractory material deforms when it reaches the creep temperature, so as to prevent the wall from collapsing downward and prolong the service life of the regenerator of the glass furnace.

The above-mentioned technical scheme is applicable to all glass furnaces as long as they include two air regenerators, including glass furnaces using natural gas or heavy oil and glass furnaces utilizing gas, because these three glass furnaces The furnace has two air regenerators, and a partition wall is arranged between the two air regenerators. Bricks connect the two sides of the partition wall and the cooling channel into a whole.

Further, because the currently used glass kiln utilizing gas also includes two gas regenerators, a middle partition wall is also provided between the two gas regenerators, and the gap between the gas regenerator and the air regenerator is There is also a partition wall between the two gas regenerators, so it is further defined that the partition wall between the two gas regenerators and the partition wall between the gas regenerator and the air regenerator are also provided with cooling channels and wall connections. Bricks, through the wall connecting bricks, the walls on both sides of the partition wall and the cooling channel are connected into a whole.

Furthermore, the middle and lower part of the cooling channel defined in the partition wall is provided with a cooling air inlet, and the upper part is provided with an air outlet, so that the entire partition wall is like a small chimney, and the middle and lower part of the wall is cooled by cooling wind (natural wind). ) inlet, and the upper part is the air outlet. This structure is simple and effective, and reduces the ambient temperature of the partition wall.

Furthermore, in the above technical solution, the middle and lower cooling air inlets and upper air outlets are provided with detachable blocking bricks for sealing the air outlets. This structure utilizes the method that the middle partition wall is made of bricks, By opening the number of sealing bricks, that is, the size of the air inlet, the air volume of the air inlet is adjusted to lower the partition wall, so that the temperature of the partition wall is moderate, and the temperature of the partition is neither too high nor too low, so that It not only guarantees the service life of the partition wall, but also does not waste too much heat in the cooling air belt. Of course, the upper air outlet is also adjusted in this way, and the specific adjustment is adjusted according to the temperature adapted to the wall.

Considering that in the later stage of the kiln, the partition wall in the regenerator is further corroded and thinned. At this time, the service life of the partition wall can be extended by accelerating the flow of wind speed, that is, further reducing the temperature of the partition wall. The above-mentioned cooling air inlet is provided with a forced air supply device to cool the wall, so as to prolong the life of the wall of the regenerator.

In addition, a collection device may also be provided at the upper air outlet to recycle the hot air to achieve the purpose of saving energy and reducing consumption.
