As the name suggests, the car paint room is where the car is sprayed and baked. At the same time, the operation steps in the paint room are directly related to the fire. Therefore, fire prevention measures must be taken before using the paint room. only if the fire incident occurs, the consequences will be very serious. So what caused the fire? Knowing the cause of the fire can better take corresponding measures, so let's talk about what the reasons are.
1. Unburned diesel (or waste engine oil) is trapped in the combustion chamber, mainly because during the injection process of the burner, the first injected diesel (or waste engine oil) is not ignited, and it is likely to stay at the bottom of the heat exchange system. However, its volatility space is limited and its volatility is very poor. An oil pool may be formed at the bottom, resulting in deflagration.
2. Due to the fuel of the car paint room, part of the fuel cannot be completely burned, resulting in the formation of new combustibles at the bottom.
3. The burner fails to ignite for many times, but the fuel injection does not stop, resulting in too much diesel (or waste engine oil) being deposited. This is very close to traditional carburetor cars, but many EFI cars have the function of clearing oil from the engine, and this kind of failure is reduced.
4. Due to the long-term use of the heat exchange system, the shell may rupture, resulting in the leakage of unburned fuel inside the heat exchange system to the outside.
5. In the process of heating and spraying paint in the car paint room, because some of the hot air circulating twice is the air containing paint mist inside the baking room. If the filter cotton is not good, there will be paint mist passing through the heating heat exchange system. The outer wall is reheated and eventually burns. The burning paint mist directly reaches the upper part of the top cotton under the action of the blower, causing the upper part to catch fire.
6. The bottom cotton material is too poor or overloaded, which weakens the filtering function of the bottom cotton, causing the paint mist-containing automobile paint room mixture to enter the air circulation system at a higher concentration again, resulting in paint mist pasted on the outer wall of the superheat exchange system. More.
Therefore, if workers are required to work safely and safely in the paint booth of a car, fire prevention measures must be taken when installing the paint booth, and then safety precautions must be taken before entering the paint booth. At the same time, their own operating behaviors must be standardized. When you leave the room after work, remember to turn off all power, so as to ensure greater safety in use and avoid fires.
