Cooling method for high temperature flue gas of bag filter:

1. Natural cooling, lengthening the length of the pipeline carrying the gas, natural convection and radiation heat dissipation of the pipeline and the surrounding air to cool the gas. It is mostly used for metal pipes. It can be used as an s-type for longer intervals. This method is simple, the cooling is weak, and the space occupied is large.

2. Cooling with water: There are two ways, one is to spray water directly into the high-temperature flue gas, and it can be used as a special spray cooling tower. The cross-section wind speed of the cooling tower is usually 2-3.5 m/s, in order to prevent water. The mist enters the baghouse and can be adjusted using a temperature control system. Another method is to use a cooling water pipe, which is installed in the pipeline for conveying gas, which can prevent the water mist from entering the bag filter and corrosion problem. This method has strong cooling capacity, small space occupation, and possibly water mist. Bag filter to make it damp or corroded.

3. Mixing cold air and inhaling a certain amount of air from the surrounding environment means mixing with high-temperature flue gas to lower the temperature. When using a trap to trap high-temperature flue gas, it can inhale ambient air together. Briefly, but the volume of the filtered gas is added a lot.
