1, high-voltage electrostatic fume purifier (plasma), the use of high-pressure gas ionization and electric field force, so that the dust particles charged from the gas separation, the submicron oil particles can also be efficiently captured, equipment fume purification power of 98% or more, is recommended to use.

2, the use of fume collection hood to collect fumes, through the exhaust fan to exhaust fumes to the outdoors. Transfer the oil smoke, purification rate of 0%.

3, water spray scrubbing tower purification technology using fume hood collection sent to the absorption tower (spray, screen, filler) method of purification, and then discharged through the exhaust fan. This product removes soot rate of about 80 to 90%. Although the removal rate meets the requirements, but the equipment device space, and the system is messy, did not reach the widespread effect.
