1. Treated air volume (Q)

Treatment air volume refers to the volume of gas that can be purified by the dust removal equipment in a unit time. The unit is cubic meters per hour (m3/h) or standard cubic meters per hour (Nm3/h). It is one of the most important factors in the manufacturer design of bag grinding dust remover.

When the bag grinding dust remover manufacturer is designed or selected according to air volume, generally speaking, the grinding dust remover manufacturer cannot be made to run under the condition that the grinding dust Remover manufacturer exceeds the specified air volume. Otherwise, the filter bag is easy to be blocked and the service life is shortened. The pressure loss increases greatly, and the dust removal efficiency also decreases. But also can not choose too much air volume, otherwise increase the equipment investment and cover an area. The reasonable choice of treatment air volume is often determined according to the process situation and experience.

2. Use temperature

For bag type grinding dust remover manufacturer, its use temperature depends on two factors, * is the filter material's maximum withstand temperature, the second is that the gas temperature must be above the dew point temperature. At present, due to a large number of glass fiber filter material selection, its maximum use temperature up to 280℃, higher than the temperature of the gas must be taken cooling measures, lower than the dew point temperature of the gas must be taken temperature measures. For bag grinding dust remover manufacturer, the relationship between service temperature and dust removal efficiency is not obvious, which is different from electric grinding dust remover manufacturer. For electric grinding dust remover manufacturer, The change of temperature will affect the specific resistance of dust and affect the efficiency of dust removal.

3. Dust concentration at the entrance

The inlet dust concentration is determined by the process of the dust point. When designing or selecting the bag grinding dust remover manufacturer, it is another important factor second only to the processing air volume. In terms of g/m3 or g/Nm3.

For the bag grinding dust remover manufacturer, the inlet dust concentration will directly affect the following factors:

⑴ Pressure loss and cleaning period. With the increase of inlet concentration, the ash accumulation speed in the same filtration area is fast, and the pressure loss is increased accordingly. As a result, the cleaning times have to be increased.

⑵ Wear and tear of filter bag and box. In the case of strong abrasive dust, the amount of wear can be considered to be proportional to the dust concentration.

It is necessary to collect dust in advance. Pre-dust collection is to add a grinding dust remover device before the manufacturer entrance, also known as pre-dust removal.

(4) The ash discharge capacity of the ash discharge device. The ash discharge capacity of the ash discharge device shall be based on the dust that can be discharged completely. The dust quantity is equal to the dust concentration at the inlet multiplied by the air volume treated.

⑸ Mode of operation. Bag type grinding dust remover manufacturer can be operated in positive pressure and negative pressure modes. To reduce fan wear, it is not appropriate to use the positive pressure mode if the inlet concentration is large.

4. Dust concentration at the outlet

The outlet dust concentration refers to the emission concentration set at the manufacturer of grinding Dust remover. The grinding dust concentration at the outlet is the same as that set at the manufacturer of grinding dust Remover. The outlet dust concentration should be determined by the local environmental protection requirements or the customer's requirements. The emission concentration of bag grinding dust remover manufacturer can generally reach below 50 g/Nm3.
