In the electrodeslagging system for acid production from zinc smelting flue gas, if the secondary voltage and current in the first electric field cannot be increased, what could be the problem? ? ?
Thread Content
After the maintenance was completed, the system was kept in operation for 5 days; neither the voltage nor the current in the primary electric field could be increased, the situation in the secondary electric field was slightly better, but the acid mist at the outlet did not meet the specifications. Rated secondary voltage: 80 KV, 600 mA. It can only reach around 40 kV and 10 mA. It is planned to disengage the primary electric field protection and increase the voltage to see if it is possible to raise the current. The air volume in the production system is now higher than before, and the internal flushing nozzles are deformed.
This shouldn’t be something that can be resolved by pipe and valve zoning, right?
Ah, I got the area wrong; no wonder the current can’t flow!
