Rotary kiln burning energy at high temperature can bring great convenience to our lives, but it is also dangerous. Its explosion-proof measures are particularly important to our people, so we need to take explosion-proof measures for the kiln equipment. So, the following article will explain it in detail for everyone, let's take a look at it together.

1. Equipment and pipelines should have a complete control device and an explosion-proof system composed of detection instruments, which mainly include: the air pressure, temperature, flow rate, meters of the rotary kiln, the outlet gas pressure, humidity meters, and gas high and low pressure alarm devices; Light signal, automatic stoker, ash dispenser contact device, pressurizer, blower interlocking device and sound and light alarm device; flammable and explosive gas dynamic detection alarm device to prevent gas leakage and explosion; kiln air main pipe, dust removal system , After cooling, the equipment and gas semi-clean pipes, distribution main pipes, etc. should be equipped with explosion-proof membranes. The front and back of the gas system should be equipped with non-reverse water seals to prevent the main pipe gas from returning when the furnace is shut down.

2. During the operation of the rotary kiln, it is necessary to debug the interlock setting of the alarm instrument before starting the furnace, adjust the pressure value of the alarm and interlock action, and test whether each interlock valve switch is correct, and then perform a few steps. A comprehensive total interlocking test; oxygen content analysis should be carried out before the coal gas is connected to the grid, and the oxygen content should be less than 1%; during the production process, special attention should be paid to the temperature and pressure changes of the gas and air. Indicators should be dealt with in a timely manner.

3. When the fire is overhauled: When the gas equipment and pipeline are overhauled, the gas source should be reliably cut off, the gas inside the gas facility should be purged and replaced, the upper and lower inlet holes, and the vent pipe should be opened; Analysis of carbon monoxide content confirms that no explosive mixture will be formed during the whole process of hot fire. In case of fire extinguishing, the gas should be stopped first, and the furnace should be analyzed after passing the ignition before re-ignition.

   This is the introduction to the explosion-proof measures of the rotary kiln. Comprehensively speaking, you can generally understand how the explosion-proof measures of this equipment are, mainly divided into three aspects. The product of kiln combustion transfers heat to the product in the form of convective heat transfer and radiation heat transfer. Therefore, it is very important to grasp the explosion-proof measures and work in the production process.
