Location of electric demisting water seal
Thread Content
The acid production system using smelting flue gas is equipped with two electrostatic demisters; the positions of the water seals in these electrostatic demisters, which were designed by different manufacturers for different systems, are not consistent； Initially, Yangzhou designed a water seal to be installed on the primary electrostatic demister inlet pipeline, with another one also installed on the secondary inlet pipeline ； Later, the water seal designed by Nanhua Institute was moved behind the secondary electrostatic precipitator and installed at the inlet of the drying tower ； Looking at it later, it was also installed between the two levels of electric mist, that is, in the secondary intake pipeline ； A recent set of electric demisting water seals has been designed for the primary intake pipeline ； Pressure and safety corresponding to different areas ； Please, fellow sailors, discuss where the safety water seal in your systems (including those for producing acid from pyrite) is located ； The safety water seal is used to protect the electrostatic demister from being collapsed or lifted and damaged ； Let’s see which location is more suitable?
After electrostatic demister No. 2, before the drying tower.
Of course, after the second layer of electrofog; if it is installed before the electrofog, it cannot provide effective protection for it
I believe that whether the safety water seal is placed at the inlet or outlet of the electrostatic precipitator, it is the design of the height of the water column in the seal that provides protection; this ensures good protection without affecting production!
