Filter material heat resistance problem
Feb 10, 2020
Environmental protection has become a global human issue. When we do not have a better ecological environment, human beings are already awakened. In China, we have promoted afforestation for thousands of families. When we raged on the earth, we did not expect our planet to be closely related to our lives. Now we take action to protect the planet, the planet that protects us but never complains.
Rhenium is tested on a 6t / h boiling furnace in a coal mine. The first stage of the furnace is pre-treated with a multi-tube cyclone, and the second stage is a rotary blow-proof bag filter. From the perspective of temperature resistance, life and price, temperature resistance 130 has water and oil resistance. C's industrial polyester filter material. The tested soot can reach the standard of 50mg / m3.
After that, 8 bag filters were installed in the process, which mainly solved the following problems: the heat resistance of the filter material
Because of the use of bag filters, due to the heat resistance of the filter material, the boiler exhaust temperature has become an important consideration. The manufacturer offers three filter materials with a temperature resistance of 130, 180 and 250 respectively. Considering that the temperature of the on-site flue gas is not too high, and the high-temperature-resistant filter material has a short life, this is to reduce the influence of water vapor and other reasons. We use waterproof and oil proof functions to withstand a temperature of 130 ℃, and the instantaneous temperature resistance of the filter material is as high as 150. This system uses multi-tube cyclone pretreatment as a pretreatment, which has the effect of reducing the temperature of the flue gas. In the case of excessively high flue gas temperatures, the manufacturer of the heat sink refers to the cooling measures of the wall cooler. The environment is something we humans must protect. In this age that requires our protection, everything is real, not false, and we must make mistakes. We can no longer deceive ourselves, because it will ruin our future.
