Solution to Explosion of Environmental Protection Lime Kiln

The newly built environmentally friendly lime kiln will contain a large amount of water in the nature. Although the building has been formed, it has not really become a solid building. Some problems may occur in the lime burning process. If these problems are not well solved in the early stage, the later repair will not only affect the progress of the project, but also affect the service life of the building. The real meaning of baking is that it can heat the water in the refractory brick, and prevent the building from being affected by a large amount of water vapor caused by the high temperature of lime during the burning process by burning the water in advance. Therefore, the refractory brick cracks. Now, the environmental protection lime kiln manufacturer will introduce the solution to the explosion of environmental protection lime kiln equipment.

The lime kiln equipment usually has stable performance and strong bearing capacity of the unit, but as a mechanical device, it is inevitable that it will be used for a long time because there will be no other texture, such as common lime kiln equipment cracking, that is, a thick layer of materials will be broken during the operation of the rotary kiln. How to solve this problem?

Generally speaking, the phenomenon of lime kiln equipment explosion is related to the ball. When the dry ball and wet ball collide with each other, the internal pressure of the lime kiln equipment is too high, which will cause explosive. This phenomenon can be solved by the following methods:

1. In the process of use, the rotary kiln shall be opened first to evaporate the internal water.

2. Prevent rapid expansion of wet bulb volume.

3. Keep the air pressure in the rotary kiln balanced, so that the ball pressure increases rapidly;

4. Keep the thickness of wet material layer of lime kiln equipment, and do not change it at will.

The energy-saving and environment-friendly lime kiln is designed with five layers of furnace shell, namely, high alumina bricks+light insulating bricks+insulating filler+insulating fiber+steel furnace shell, 1000mm thick. The outer furnace shell is slightly good. The design life of the refractory insulation layer in the furnace is more than 5 years. In order to effectively use energy, the whole kiln body is fully sealed, which greatly reduces the loss of heat from the upper and lower parts. Combustion supporting air is blown from the lower part of the kiln body. After passing through the cooling zone, it becomes hot air through heat exchange, and then it is blown into the furnace. The upper raw materials are added to the pre heating zone for heat exchange with the rising high-temperature flue gas. Due to two-way heat exchange, the temperature of the discharged finished ash is below 40 ℃, The temperature of the flue gas discharged from the upper part is below 140 ℃. After actual measurement, the calorific value and utilization rate of the fuel are above 80%.
