Description

Oil smoke filter screen

Technical Field

The utility model relates to the technical field of oil fume filtering equipment, in particular to an oil fume filtering screen.

Background

At present, the oil fume purification in the catering industry is only simple electrostatic purification, and the oil fume is collected by a fan and a wind cabinet type negative pressure through a fume hood, guided by a flue, electrostatically adsorbed, purified and discharged into the air; when oil smoke passes through the smoke hood, the flue and the electrostatic purifier, a large amount of grease and particles are attached to the wall surface of the flue pipe, a large amount of accumulated oil can be formed in the smoke collecting hood and the flue after a long time, and serious fire safety hidden dangers exist. With the implementation of the new national standard and management method, the service life of the purifier is seriously shortened because of the motor caused by regular cleaning corrosion, oil fume corrosion, high temperature and high humidity, and the highest emission concentration of the oil fume emission standard of the catering industry is 1.0mg/m 3; because of often washing the reduction of clarifier work efficiency, the oil smoke discharges and also can not accomplish the normalized up to standard.

After the oil smoke filter screen among the prior art filters, still need to use a large amount of clear water to wash flue and clarifier when clean to can use chemicals such as industrial caustic soda in the cleaning process, during sewage directly arranges the sewer, does not possess the standard of direct emission, very big to environmental pollution.
