The resistance of the drying tower has increased
Thread Content
Recently, the resistance in the drying tower during the production process has often exceeded twice the design value. Normal production can be resumed each time a shutdown is requested to replace the drying mesh foam catcher. What could be the reason for the drying mesh foam catcher getting clogged so easily? Our factory produces acid from lead smelting flue gas
What is the electric fog configuration? For example, in the case of a two-stage conductive fiberglass electrosmog system, what is the secondary current of the electrosmog? What are the purification indicators (dust, fog, water, arsenic, fluoride)?
Secondary electrostatic fog: Secondary current for #1 is 60 mA, and for #2 it is 80 mA. As for other purification parameters, the factory’s laboratory does not have the necessary technical capabilities to measure them; operations are carried out based on experience
From the perspective of the electric fog operation parameters, they are not ideal. By looking through the upper viewing mirror of the secondary electrostatic fogger, can one see whether the inside of the electrostatic fog is filled with mist or clear and transparent? The dust and water mist parameters at the fan outlet still need to be analyzed. As expected, the metal mesh in the dryer tower of this device is likely to be clogged due to excessive dust levels.

The eyepiece is not very clear anymore; it hasn’t been replaced in 12 years, and it doesn’t seem to have any fogging at first glance. Recent analyses show that the lead content in the purified filter residue is around 50%, sulfur around 7%, arsenic around 2%, and selenium around 12% – which seems unbelievable
May I ask how often you clean the electrostatic demister, and what is the situation regarding the discharge of waste from the purification system?
The two electrostatic mist removers are cleaned once each during the morning shift, for half an hour each time. There are three to four tanks of sludge in the purification filter daily, and the water supply for purification is 2 cubic meters per hour
The dust removal efficiency of the electrostatic precipitator and that of the subsequent purification stages are not satisfactory, resulting in an increase in the pressure drop across the equipment downstream.
The cause lies at the source; recently, the interval between cleaning and drying the silk traps has been around 10 days, while normally 1–3 months is sufficient. It’s unclear what components are in the raw material that give it such a strong destructive effect
I’ve been to many factories, and it’s difficult to find an experienced lab supervisor (or keep one in place).
