The following three methods are more effective in judging whether the oil fume purifier should be cleaned. As long as the oil fume purifier is in use, it must be cleaned.

With the launch of the blue sky defense war, all localities have paid close attention to the issue of cooking fume emission. In order to respond to the national policy, it is an inevitable measure for the catering industry to install an efficient oil fume purifier to discharge oil fume, and the oil fume purifier is a good choice. However, after installing the fume purifier, it needs regular maintenance and cleaning to maintain the efficient performance of the equipment. The following small series tells you how to judge whether the fume purifier needs cleaning.

1. The purification effect is not ideal after being used for a period of time

At present, the national catering industry should install oil fume purifiers and meet the local emission requirements, and most of the installed regular oil fume purification equipment need to achieve the smoke-free effect by visual inspection. No matter which brand of oil fume purification equipment is installed, after a period of use, the effect is not as good as when it was just installed. If you can still see a little bit of oil fume with the naked eye or smell an odor even at the exhaust outlet, then you are telling catering users that the equipment should be cleaned and maintained.

2. Abnormal sound or noise occurs in the oil fume purification equipment

After the installation of the oil fume purification equipment produced by ordinary manufacturers, there is no abnormal sound and noise during operation. You may hear the sound at a close distance. It is normal for the fan to make noise, so don't worry about it.

However, if there is abnormal noise and noise in the oil fume purification equipment, and the oil fume purification equipment has not been cleaned and maintained for a long time, a lot of oil stains will accumulate inside, which may cause abnormal noise. If you hear abnormal noise, you should maintain and clean the oil fume purification equipment.

3.? On-line monitoring equipment for lampblack

Environmental-friendly on-line monitoring equipment for lampblack can monitor the lampblack concentration, non-methane total hydrocarbon concentration, particulate matter concentration, sensor status, lampblack purifier status, fan status, maintenance status, product installation area and so on in real time on the mobile phone or PC, and can freely set the alarm limit of lampblack concentration emission. When it exceeds the standard, the platform will automatically give an alarm. At this time, it tells you that the lampblack purification equipment should be cleaned and maintained.
