Bypass system. The flue gas can be directly discharged from the bypass pipe during the inspection, and then the boiler is overhauled.
Pre-spray equipment. When the boiler is fueled, there will be a lot of fumes in the smoke. Because the soot is adsorbed on the outer surface of the bag to form a blockage, the pre-spraying equipment will spray the fuel into the boiler, and spray lime powder into the flue gas pipe to absorb the fumes in the flue gas, and then deal with the bag blockage problem.
Cool air valve. The cool air valve is equipped with an on-line temperature measurement system that monitors the flue gas temperature in real time. When the temperature of the flue gas exceeds the temperature acceptable for the bag, the cool air valve will open actively, and the precipitator will inhale a part of the natural air to cool down to the purpose of maintaining the bag.
Boiler dust collector insulation. After the fuel is incinerated by high temperature, the water in the fuel will become water vapor and smoke together into the baghouse. When the flue gas enters the bag filter, it will naturally cool down because of the large temperature difference between the surface, so that the water vapor in the flue gas will constitute the condensation water adsorbed on the outer surface of the bag. Moisture and dust will form a mud on the outside of the bag and then present a paste bag phenomenon, which makes it impossible to filter the bag. After the dust collector is kept warm, the flue gas will not be cooled after entering the dust collector, and the water vapor will not constitute condensed water to avoid the occurrence of the paste bag phenomenon.
