The pressure loss of desulfurization, denitrification and dust collector refers to the pressure drop or resistance of gas from the dust collector to the outlet. The pressure loss of desulfurization, denitrification and dust collector depends on the following three factors:

1. The pressure loss of the dust layer accumulated on the filter material.

2. Pressure loss of desulfurization, denitrification and dust collector structure.

3. Pressure loss of filter material. It is related to the properties of the filter material.

When designing or selecting a desulfurization and dust collector based on air volume, it is generally not allowed to operate the dust collector beyond the specified air volume. Otherwise, the filter bag is prone to clogging, the service life is shortened, the pressure loss increases significantly, and the dust removal efficiency also decreases; But the air volume should not be chosen too high, otherwise it will increase equipment investment and land occupation. So, desulfurization, denitrification, and dust collectors need to handle air volume frequently. The air volume to be processed is often selected based on the process conditions and experience!
