there are many kinds of dust removal equipment for sand dryer, such as bag filter and electrostatic precipitator, which are often seen. what are the differences between these two kinds of dust removal devices?
bag dust collector has the advantages of high dust removal efficiency, wide range of air handling, simple structure and easy maintenance and operation. it is an excellent dust removal equipment. but many manufacturers of sand dryer choose esp, which is why? this is because esp is more suitable for the dust removal of sand dryer than bag filter. esp has many advantages in the dust removal system of sand dryer.
compared with bag filter, esp has the following six advantages in dust removal of sand dryer.
firstly, in the dust removal work of sand dryer, esp needs less maintenance, but its operation rate is relatively high.
secondly, the investment is relatively small, which saves much more than using bag filter.
thirdly, the esp used in sand dryer is relatively stable in operation, and the secondary voltage and current can basically maintain a relatively stable state.
fourthly, the dust removal effect is very good, and there will be no phenomenon of discharge electrode wrapping and anode wrapping. the anode of sand dryer electromechanical precipitator is usually made of stainless steel circular tube, and the upper and lower wells are not completely fixed. under certain impact vibration, the circular tube will rotate, which enhances the effect of dust cleaning. at the same time, because stainless steel is used in both cathode and anode, the surface finish of stainless steel material is higher than that of ordinary material, and the dust is easy to fall off.
fifth, the control system of electromechanical precipitator for sand drying is convenient and practical, and the failure rate is low. the control system used in the electromechanical precipitator for sand drying has a variety of operation modes, and its management function is perfect. it is convenient to supervise and control in operation, and it can set and change parameters or operation modes in operation. at the same time, a variety of protective measures are set up.
