650m3 Volume Dust Control Systems Carbon Steel Installing Explosion Relief Valve

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 rule:

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.

Tip:

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.
