Why should the fume purifier be cleaned regularly?

1、 Importance of oil fume purifier to catering industry

With the rapid development of economy, people have higher and higher requirements for the living environment, but lampblack is very harmful to the environment and the body. As carcinogens such as benzomiao, volatile nitrosamines and heterocyclic amines suddenly change human cell tissues in kitchen fume, cancer occurs. Acrolein is the main component of lampblack. Invasion into the respiratory tract will cause chronic pharyngitis, rhinitis, tracheitis and other respiratory diseases. The strong permeability and viscosity of lampblack also have a great impact on the surrounding environment. The lampblack purifier is a device for purifying lampblack generated in the process of cooking and food processing.

2、 Working principle of electric lampblack purifier

The prefilter flows large oil particles into the oil tank under its neutral action through mechanical action. The remaining small particle pollutants enter the secondary device - high-voltage electrostatic field, and there are two levels in the electrostatic field. The first is the ionizer. The strong electric field charges the particles to become charged particles. When these charged particles reach the secondary dust collector, they are immediately absorbed by the collecting electrode and returned to the special oil collecting basin. Clean air is discharged from the outside.

Regular cleaning and maintenance is of great significance to the oil fume purifier.

According to the working principle of the oil smoke purifier, the oil smoke purifier should be cleaned and maintained regularly during use to maintain the working efficiency of the oil smoke purifier. Irregular cleaning and maintenance will cause the following hazards:

1. For the oil fume purifier itself, it is mainly based on the physical principle to remove the oil fume, so as to achieve the effect of oil fume purification. As the use time of the fume purifier goes by, the internal oil stain will gradually deposit. If it is not cleaned and maintained regularly, it will not achieve the function of filtering lampblack. It will also cause kitchen lampblack, leading to a decline in the kitchen environment, and even burning the lampblack purifier may cause a fire;

2. When the oil stain deposited in the oil fume purifier reaches a certain level, the oil fume purifier will lose its function, and the oil fume cannot be directly purified and discharged, causing environmental pollution. It is easy to cause complaints from surrounding residents. According to the provisions of Article 91 of the Law on the Prevention and Control of Atmosphere, in violation of the provisions of this law, food service operators that discharge lampblack do not install lampblack purification facilities, the lampblack purification facilities are used abnormally, or other lampblack purification facilities are not used. Those who discharge lampblack in excess of the discharge standards shall be ordered to make corrections and fined not less than 5000 yuan but not more than 50000 yuan by the supervisory and administrative department designated by the local people's government at or above the county level; Those who refuse to correct,

3. After the oil smoke purifier loses its effect, it is easy to cause the kitchen oil smoke to be unable to be discharged, resulting in the deposition of kitchen oil stains, which is not conducive to kitchen cleaning; There are a lot of aldehydes in lampblack, which have different degrees of pungent odor and toxicity, and are harmful to human health. The smoke smell is mainly caused by unsaturated aldehydes. Polycyclic aromatic hydrocarbons (PAHs) are carcinogens and do great harm to kitchen staff. The hazards of cooking fume are far more than what we mentioned, but the reason for these hazards is that the fume purifier is not cleaned regularly.
