650 m3 Blast furnace dry gas cleaning plant industrial dust collector silos
In iron and steel industry , blast furnace is the first choose to produce iron melts, during this process , it will come out lots of gas.
There were venture scrubbers and electric de-dusting system to filtering the gas in past years, but there was second pollution to water. In China market , after several years researched and practiced , then developed the pulse-jet cleaned system.
The general pressure of the BF plant gas is 0.08Mpa-0.14Mpa,the temp range 100-250 degree after cooling, the design for filter velocity range 0.3-0.6m/min, ash content 8Ng/Nm3-12Ng/Nm3.
Considering the explosion , the design for dust tube houses install explosion relief valve.
Filter media needs high temperature repellent non woven fabrics, the request of ash content after GCP less than 10mg/Nm3, even less than 3mg/Nm3 to 5mg/Nm3 in some applications, it is enough cleaning for the next process—TRT .
Different dust separation procedures require different weight and air permeability values for filter media.
The more effective the cleaning process, the more compact and heavier the filter medium can be.
The high emission control standards, the heavier the filter medium should be.
If these factors are well considered in advance, running costs like electricity for the fan or pressurized-air for the cleaning pluses can be saved later on in a great amount.
