According to the national regulations, bag filter must be used for waste incineration tail gas treatment. Due to its complex and changeable working conditions, it is easy to cause various damages or even failures in practical application. We suggest that customers give priority to 100% PTFE to adapt to the following harsh working conditions:
1. The temperature is unstable, generally 150-200 ℃, sometimes as high as 250 ℃; the temperature resistance of filter material is very high.
2. The filter material is required to have certain wear resistance.
3. The filter material should have strong resistance to moisture;
4. It contains high oil substance. The oily substances produced in MSW incineration mainly come from the uncertain oily substances of MSW itself and the oily substances produced in the process of starting up or fueling combustion.
5. High oxygen content (oxidizing substances mainly include O2, NOx, Br2, Fe2O3, etc., with strong oxidation, sometimes as high as 15% - 30%)
At the same time, 100% PTFE has the following advantages:
A adapt to the new standards of national environmental protection and people's increasing demand for environment.
B. effective ways to control dioxins. At present, the national standard for dioxin emission is 1ng-teq / Nm3, and the local standard for developed areas such as Yangtze River Delta has been raised to 0.1ng-teq/nm3.
C can ensure that the system runs in the most safe and stable state. According to the investigation, in the current operation of more than 50 garbage power plants, the use of filter materials is not optimistic, such as bag breaking, high resistance, oxidation, membrane removal The reasons for bag quality, boiler / dust collector operation and operation management are complex and diverse. The adaptability of 100% PTFE to working conditions is very strong, which can ensure long-term stable and safe operation.
The 100% PTFE operation stability and long life can reduce the labor cost of bag changing and save the cost of boiler shutdown due to bag changing, which shows high application value.
