(1)Pressure loss and ash clearing period
With the increase of inlet concentration, the ash deposition rate is fast and the pressure loss increases with the same filter area. The result is that the ash removal frequency has to be increased.
(2) the wear of filter bag and box
In the case of strong abrasiveness of dust, the amount of wear can be considered proportional to the concentration of dust.
(3) whether there is a need for the precollected dust
Pre dust collection is to add a level of dust removal equipment before the entrance of the dust collector, also known as the pre stage dust removal.
(4)Ash discharging capacity of ash discharging device
The ash removal capacity of the ash removal device shall be based on the dust that can be discharged. The dust quantity is equal to the inlet dust concentration to be treated by the volume of air.
(5)Operation mode
The bag filter is divided into two operation modes: positive pressure and negative pressure. In order to reduce fan wear, the positive pressure operation mode is not suitable for large inlet concentration.
The advantages of the wet dust removal of the desulfurization and dust remover are easy to maintain and can be prepared by different dedusting agents, at the same time, the effect of dust removal and desulphurization is achieved. The following is the design principle of the desulfurization and dust removal device.
1, reduce the investment and operation cost of desulphurization system as far as possible. After the completion of the desulfurization system, the maximum social and economic benefits can be achieved by the optimized process.
2, choose advanced and reliable desulfurization process to ensure the efficiency and safety of the system while ensuring the desulfurization efficiency.
3, fully combining the objective conditions and requirements of the user, according to local conditions, maximizes the use of existing resources and limited space space, optimizes the combination, and establishes a pertinent and practical technical scheme.
4, paying attention to the efficiency of equipment, we should minimize the operation cost of the system and pay attention to the rational selection of equipment.
